Warning Signs Your Lincoln's Battery Needs Attention This Summer

Service  |  St. Louis, MO The signs your tires need attention before a summer road trip, and how to check them yourself in your driveway. Summer is when a Lincoln SUV earns its keep. A weekend at Lake of the Ozarks, a drive out to Hermann, a long run up I-70 toward Columbia or Kansas City. Tires that felt fine on the commute through Kirkwood or Chesterfield can act very differently with the luggage in and a few hours at highway speed. Most tire trouble gives you a warning first: a vibration you got used to, tread wearing unevenly, or a slow leak that needs air every couple of weeks. Those are easy to shrug off until you're on the shoulder of the interstate with a flat. Quick answer: Uneven wear, tread under 4/32 of an inch, cracks in the sidewall, a vibration at highway speed, or a tire that keeps losing air are all reasons to get your tires inspected before a road trip. Most of it takes a few minutes to check and it's far easier to handle at home than on the side of the road. Road trip tread 4/32 of an inch or more Legal minimum 2/32 in most states Tire age Check the date code In this post Tread depth Uneven wear Highway vibration Sidewall damage Tire age Rotation and pressure How Do You Know If Your Tread Is Too Worn? Two coins will tell you most of what you need to know. Do both before a trip. 1 The penny test Put a penny in the tread groove with Lincoln's head pointing down. If you can see all of his head, the tread is down to about 2/32 of an inch. That's the legal minimum in most states, and well past the point where a tire grips the wet. 2 The quarter test For a road trip, aim for 4/32 or more. Put a quarter in the groove with Washington's head down. If tread covers part of his head, you still have a decent margin. Wet braking distance grows noticeably below 4/32, which is why we use that number for a trip and not the legal minimum. What Does Uneven Wear Mean? Uneven wear tells you something about the vehicle, not just the tire. Wear on the outer edges often points to underinflation, and wear down the middle to overinflation. Heavier wear on one side can mean an alignment that has drifted, sometimes from a single pothole on Manchester Road. Cupping or scalloped patches, often a sign of worn suspension parts Feathering, where tread edges are sharp on one side and rounded on the other, usually an alignment issue Heavier wear on the inside or outside edge, also usually alignment Flat spots or bald patches from a wheel that's out of balance A tire can look new on the surface and still hide one of these patterns. A hands on inspection catches what a quick glance from the driveway won't. Why Does a Vibration at Highway Speed Matter? A vibration that shows up around 55 miles per hour and up usually points to a wheel that's out of balance, or a tire with a problem inside. Over a couple of hours on I-44 it puts real stress on the suspension and steering. If it comes and goes, or gets worse after a bump, get it checked before the trip and not during it. Balancing a wheel is usually a quick job. Tire Care Advice Schedule a Tire Inspection What About Sidewall Cracks and Bulges? Cracking along the sidewall, sometimes called dry rot, tends to show up on older tires even when the tread looks fine. Missouri summers are hard on rubber, and repeated heat and UV can crack a tire before the tread wears out. A bulge or bubble in the sidewall The tire's internal structure has been damaged, often by a pothole or a curb. It can fail without warning under a loaded vehicle at highway speed. Replace it before any longer drive. A tire can look new on the surface and still hide one of these patterns. Does Tire Age Matter Even If the Tread Looks Fine? Yes. Most manufacturers recommend replacing tires six to ten years after they were made, no matter how much tread is left, because the rubber breaks down over time. That matters for a second vehicle, or for a Lincoln that sits for long stretches in a garage in Frontenac or Ladue. The date is stamped on the sidewall as a four digit code, two digits for the week and two for the year. Our service team can read it for you during any visit. Should Tires Be Rotated Before a Long Trip? A rotation helps all four tires wear evenly, which stretches the life of the set. If it's been more than 5,000 to 7,000 miles since your last one, book it before the trip. St. Louis driver tip Set your pressure to the number on the sticker inside the driver's door, not the number printed on the tire. The tire's number is the maximum, not the recommendation. Underinflated tires run hotter at highway speed, and heat is a common cause of tire failure. Book it your way Schedule online, in the Lincoln app, or call us at 314-729-2700.

See Pickup and Delivery Questions Drivers Ask About Tire Wear and Replacement How often should tires be replaced? Most tires last somewhere between 40,000 and 60,000 miles, depending on the tire, how you drive, and how well they're rotated and maintained. Tread depth and age both matter, so a tire can need replacing sooner if it shows uneven wear or cracking. Can I mix new and used tires on the same vehicle? It's not recommended for most vehicles, especially all wheel drive Lincoln SUVs, since a gap in tread depth can affect handling and put uneven strain on the drivetrain. If only two tires need replacing, the newer pair usually goes on the rear axle. What does the wear bar on a tire indicate? The wear bar is a raised strip molded into the tread groove. It sits flush with the surrounding tread once depth drops to about 2/32 of an inch. If the tread is level with it across a good part of the tire, replacement should happen soon. Questions Drivers Ask About Tire Pressure What tire pressure should I use for a loaded road trip? Use the pressure on the sticker inside the driver's door jamb. Some owners add a few pounds when the vehicle is heavily loaded, which can be fine, but check the right adjustment for your Lincoln with our service team. How often should tire pressure be checked? Once a month is a good habit, plus a check before any longer trip. Pressure drops with temperature swings, so a tire that was fine in warm weather can read low once it cools off. What does the tire pressure warning light mean? It comes on when one or more tires has dropped well below the recommended pressure. Check all four with a gauge as soon as it's safe and add air to the door jamb number. If the light stays on, a sensor may need attention, and our service team can check it. Questions Drivers Ask About Tire Service How long does a tire inspection take? A basic visual check and pressure check is quick. If a rotation or balance is needed, plan for more time. Ask your advisor for an estimate when you book, so you can fit it in before a weekend trip. Is a spare tire or repair kit enough for a road trip? A properly inflated spare or a working repair kit is useful, but neither replaces four tires in good shape. A spare is meant to get you to the nearest service location, not to be driven far at highway speed. Can a tire be repaired instead of replaced? A puncture in the tread area, away from the sidewall, can often be repaired with a proper plug and patch. A sidewall puncture, a repeat puncture in the same spot, or damage near the edge of the tread usually means replacement. Questions Drivers Ask About New Tires and Setup What size tires does my Lincoln use? The size is printed on the sticker inside the driver's door jamb and in the owner's guide, and the same code is molded into the tire sidewall. Match the size and load rating for your specific vehicle, not whatever the last set happened to be. Do new tires need to be balanced? Balancing is a standard part of mounting new tires, since even a small weight difference around the wheel can cause a vibration at highway speed. It's a quick step that protects ride comfort and tire life. Should I get an alignment when I buy new tires? An alignment check is a smart companion to new tires, since a drifted alignment can wear a fresh set unevenly in a short time. If your old tires wore on one edge, checking alignment at the same visit is even more useful. Questions Drivers Ask About Seasonal Tire Care Does St. Louis weather affect how long tires last? Yes. Summer heat ages rubber faster, and winter road treatments and temperature swings add their own wear. If you drive year round in the St. Louis area, a tire check twice a year makes sense, once before summer and once before winter. Should all season tires be swapped for winter tires in St. Louis? Most St. Louis drivers do fine year round on a quality all season tire, since our winters are milder than up north. If you regularly drive in snow or ice, or want extra margin on the coldest days, dedicated winter tires are worth a look. Why does my tire pressure drop when the weather gets colder? Air contracts as temperatures fall, and tire pressure drops roughly one pound per square inch for every ten degree drop. That's why a tire that read fine in October can set off a warning on the first cold morning of the season. Planning a Road Trip Soon? Have your tires inspected before you load up and go.

Service  |  St. Louis, MO What your Lincoln's check engine light is telling you, when to keep driving, and when to pull over. The light comes on during the drive home on I-64, or while you're sitting in traffic on Manchester Road, and the first thought is usually the worst one. Sometimes the cause is minor. Sometimes it isn't. The light can't tell you which, so it helps to know what to do next. If you've been searching "check engine light near me," this covers steady versus flashing, the usual causes, what a diagnostic scan does, and how to get your Lincoln checked. Quick answer: A steady check engine light means the vehicle stored a fault and should be checked soon. A flashing light is more urgent: ease off, avoid hard acceleration, and get it looked at as soon as you safely can. A diagnostic scan reads the stored code, and a technician uses it as a starting point to find the cause. Steady light Get it checked soon Flashing light Ease off, get help now Gas cap Tighten until it clicks In this post What it means Steady or flashing Common causes The scan Safe to drive? What to tell the advisor What Does the Check Engine Light Mean on a Lincoln? The light is part of the vehicle's onboard monitoring. When a system that affects engine performance or emissions reports a reading outside its normal range, the vehicle stores a trouble code and turns the light on. It doesn't name the problem. It tells you something was detected, and a technician with the right tools still has to find the cause. Is a Steady Light Different From a Flashing One? Yes, and the difference matters. A steady light usually means a fault was logged, and the vehicle can generally be driven carefully while you arrange service. Don't ignore it for weeks, though. Flashing light The vehicle is asking for attention now. It can point to a condition that may harm parts of the exhaust system if you keep driving hard. Ease off the accelerator, avoid towing or heavy loads, and get it checked as soon as you safely can. Rough running or lost power Pull over somewhere safe and call for help. What Commonly Turns the Light On? The list of possible causes is long. A short version shows the range from simple to more involved: A loose, damaged, or missing gas cap A sensor reading incorrectly, such as one that watches exhaust or airflow An emissions component that's wearing out Ignition parts like spark plugs or coils that are misfiring Other engine or transmission faults St. Louis driver tip If the light came on right after you filled up, check the gas cap first. Tighten it until it clicks and drive normally for a bit. If the light stays on, have the vehicle scanned. What Does a Diagnostic Scan Tell You? A technician connects a scan tool to your Lincoln and reads the stored trouble codes. The code points to the system or circuit where the problem was detected, which narrows the search. A code is a starting point, not a verdict. The same code can come from more than one cause, so the technician follows up with more testing before recommending a repair. That extra step keeps you from paying to replace a part that wasn't the problem. A code is a starting point, not a verdict. Schedule Lincoln Service View Service Specials Is It Safe to Keep Driving With the Light On? With a steady light and a vehicle that drives normally, short trips to get it checked are generally reasonable. Don't let it sit for weeks, because a small issue can grow while the light stays on. With a flashing light, a rough running engine, a burning smell, or a noticeable loss of power, stop driving as soon as it's safe and have the vehicle looked at. When in doubt, call our service team and tell us what you see. What Should You Tell the Service Advisor? Details help the technician. Tell the advisor when the light first came on, whether it's steady or flashing, and whether anything changed around then, like fueling, a long trip, bad weather, or a rough start. Mention how the vehicle feels too: hesitation, odd noises, poor fuel economy, or other warning lights. You can schedule through our website or call the service department.

Pickup and Delivery is complimentary for vehicles within the new vehicle limited warranty, so we can come get the car while you stay at work. See Pickup and Delivery Questions Drivers Ask About the Warning Light What does a steady check engine light mean? It means the vehicle detected a fault and stored a code. The cause could be small or significant, so schedule a diagnostic soon instead of waiting for it to clear. Why is my check engine light flashing? A flashing light signals something more urgent than a steady one, often related to engine performance. Ease off, avoid heavy loads, and have the vehicle checked as soon as you safely can. Can the check engine light turn off on its own? Sometimes it does, for example after a loose gas cap is tightened and the vehicle completes its checks. The stored code may stay on record, so a technician can still tell you what triggered it. Questions Drivers Ask About Common Causes Can a loose gas cap turn on the check engine light? It can, because the fuel system is monitored for leaks. Tighten the cap until it clicks and give the vehicle some normal driving. If the light stays on, get it scanned. Do worn spark plugs or ignition coils trigger the light? They can. A misfire from worn ignition parts is a common reason for a warning, and it may come with rough running or hesitation. A technician can confirm which part is responsible. Can an oxygen sensor or emissions part cause the light? Yes. Sensors and emissions components are monitored closely, and a failing one can set a code. Swapping parts on a guess wastes time and money, so let testing confirm the cause first. Questions Drivers Ask About Diagnostics What does a car diagnostic scan include? A technician reads the stored codes with a scan tool, reviews related data, and then inspects or tests the system the code points to. The goal is to find the cause, not just the code. Is a free code read the same as a full diagnosis? No. A basic code read tells you what was stored. A full diagnosis goes further to find out why, and that's what lets a repair be recommended with confidence. Should I clear the code myself? Clearing a code erases information a technician can use, and it doesn't fix the cause, so the light will probably come back. Have the vehicle scanned before anything is cleared. Questions Drivers Ask About Driving and Safety How long can I drive with the check engine light on? With a steady light and normal driving, plan to schedule service promptly, within days instead of weeks. A flashing light or a rough running engine calls for much quicker action. Will the light affect an emissions inspection? An active warning light can be a problem at inspection time, since the system is tied to emissions monitoring. Check current requirements for your area, and get the issue diagnosed before your test date. Does every warning light mean a major repair? Not at all. Many causes are simple and some are minor. The point of a diagnostic is to learn which situation you have so you can make an informed decision. Questions Drivers Ask About Scheduling Service How do I schedule a diagnostic at Dave Sinclair Lincoln St. Louis? Use the service scheduling page on our website or call the service department at 314-729-2700. Describe the light and how the vehicle is driving so we can plan the visit and have a technician ready. Can the service team check other dashboard warnings too? Our technicians can look at other warning lights during the same visit. Tell us about every light you've seen, and roughly when it showed up, so nothing gets missed. What if my check engine light comes and goes? An intermittent light still means a fault was detected at some point. Note when it appears, like cold starts or rain, and share that with the advisor to help track it down. Ready for Answers?

Service  |  St. Louis, MO How to tell if your Lincoln needs an alignment after pothole season, and what to tell the advisor when you call. Every March it goes the same way around St. Louis. A hard freeze, a quick thaw, then a fresh crop of potholes on Manchester Road and the I-64 ramps. You hit one you couldn't dodge, the steering wheel jerks, and for the next few miles you wonder if something just changed. If you've been searching "wheel alignment near me," this covers what a bad alignment feels like, what an alignment does, what a pothole can do to your Lincoln, and how to describe the problem so our team finds it fast. Quick answer: A Lincoln that pulls to one side, a steering wheel that sits off center on a straight road, or tires that wear unevenly are the classic signs of an alignment problem. Potholes and curbs are common causes. Getting it checked early protects your tires and keeps the vehicle tracking straight. Common cause Potholes and curbs Classic sign A pull to one side Protects Your tires In this post The signs What alignment does Potholes Tire life Alignment or balance What to tell the advisor What Are the Signs Your Lincoln Needs an Alignment? Most alignment trouble shows up in how the vehicle drives. Watch for these: A pull to one side The vehicle drifts on a flat, straight road when you loosen your grip. A crooked steering wheel The wheel sits off center while you're driving straight. Uneven tire wear One edge of a tire wears faster than the other. Loose steering The steering wanders or doesn't settle back to center after a turn. A gentle squeal A tire squeals softly in ordinary turns. Crowned roads can pull any vehicle slightly toward the shoulder, so try a few different roads before you decide. If the pull follows you everywhere, it's worth a look. What Does a Wheel Alignment Do for Your Lincoln? Alignment is the setup of the wheels so they point the same direction and meet the road flat and square. When it's right, the vehicle tracks straight, the steering returns to center, and each tire carries its share of the work. A technician measures the current settings, compares them with what the manufacturer calls for, and adjusts whatever has drifted. You get a straighter, calmer drive and a clear record of what was found. Can a Pothole Knock Your Lincoln Out of Alignment? Yes, and it doesn't take a dramatic hit. A sharp jolt from a frost heaved pothole can nudge suspension parts enough to change how the wheels sit. Curbs, railroad crossings, and the broken edges on ramp pavement do the same thing. St. Louis driver tip If you hit something hard, don't wait to see whether the feeling goes away. A bigger impact can bend a wheel, bruise a tire sidewall, or stress a suspension part, and none of that fixes itself. Have it looked at, and tell the advisor roughly when and where it happened. Schedule Lincoln Service Tire Care Advice How Does Alignment Affect Tire Life? Tires wear evenly only when they meet the road evenly. If the wheels point slightly the wrong way, the tread scrubs against the pavement instead of rolling, and the edge of the tire pays for it. The wear often starts on the inside or outside shoulder, where it's easy to miss. That's why alignment and tires belong in the same conversation. A tire that wears out early because of alignment costs real money, and a new set on a vehicle that's still out of alignment can start the same wear all over again. Is It Alignment, or Do Your Tires Need Balancing? The two get mixed up all the time. Balance is about weight being spread evenly around the tire and wheel. When it's off, you usually feel a vibration through the steering wheel or the seat at highway speed. Alignment is about direction. When it's off, you feel a pull or a crooked wheel, or you see uneven wear. Some vehicles have both problems after a hard pothole hit, which is one more reason to describe exactly what you feel. Alignment is about direction. What Should You Tell the Service Advisor? The more specific you are, the faster the technician can narrow it down. Tell your advisor: Which direction the vehicle pulls and whether it happens on every road Where the steering wheel sits when you're driving straight Whether you hit a pothole or curb and roughly when Whether you feel a vibration, and at what speed Whether you've noticed uneven wear on the tires Ask for a tire inspection at the same visit. The tires keep a record of what the alignment has been doing, and a quick look at the tread can show whether the problem has been building for a while. Book it your way Schedule online, in the Lincoln app, or call us at 314-729-2700. Pickup and Delivery is complimentary for vehicles within the new vehicle limited warranty, so we can come get the car while you stay at work. See Pickup and Delivery Questions Drivers Ask About Alignment Symptoms Why does my Lincoln pull to one side? A steady pull on a flat road usually points to an alignment issue, though uneven tire pressure or a worn tire can cause it too. Check your pressures first, then have a technician look at the alignment and the tires together. Why is my steering wheel crooked when I drive straight? The steering wheel and the road wheels have drifted out of agreement, which is a common result of a pothole or curb hit. The fix is an alignment, and the technician will set the wheel back to center as part of it. Can uneven tire wear come from alignment? It's one of the most common causes. Tread that wears on one edge, or in a feathered pattern, often traces back to wheel direction. Rotation and pressure matter too, so a tire inspection helps sort out the cause. Questions Drivers Ask About Potholes and Winter Driving Should I get an alignment after hitting a pothole? If the vehicle pulls, the wheel sits off center, or you just hit something hard, yes, get it checked. Even a hit that seems minor can shift the settings, and checking early costs less than replacing a worn tire. Why are potholes so common in March around St. Louis? Water gets into cracks, freezes, expands, and then thaws, which breaks up the pavement. Our winters swing above and below freezing often, so late winter leaves heavily patched roads from Manchester Road to the interstate ramps. Can a curb hit cause the same trouble? It can. Scraping or bumping a curb while you park or turn can move suspension parts just like a pothole does. Tell the advisor about it, since it helps explain what the technician finds. Questions Drivers Ask About Alignment and Tires Will an alignment fix a vibration? Not usually. A vibration at highway speed more often points to wheel balance or a damaged tire. A technician can check balance and alignment in the same visit if you aren't sure which one you have. Should I have alignment checked when I buy new tires? It's a smart habit. New tires deserve to start on a vehicle that tracks straight, and an alignment check protects what you just spent. Ask your advisor to look at it when the tires go on. Does poor alignment shorten tire life? It can, sometimes by a lot. Tires that scrub instead of roll lose tread faster, and the wear is uneven, which can make a set unusable before the tread is gone across the whole tire. Questions Drivers Ask About the Service Visit What does an alignment appointment involve? A technician measures where the wheels sit, adjusts what's out of position, and often inspects steering and suspension parts for wear or damage that would keep the setting from holding. You get a summary of what was found. How long does an alignment visit take? It depends on the vehicle, what the inspection finds, and how busy the shop is. Your service advisor can give you a realistic window when you schedule. Is alignment covered by my Lincoln warranty? Coverage varies by situation and by vehicle, so check before you assume either way. Ask your advisor to review your warranty and any service plan for your vehicle. Questions Drivers Ask About Scheduling at Dave Sinclair Lincoln St. Louis How do I schedule alignment service at Dave Sinclair Lincoln St. Louis? Use the Lincoln service page on our website or call the service department at 314-729-2700. Mention the pull, the off center wheel, or the pothole so the right amount of time is set aside. What should I note before I bring my Lincoln in? Write down what you feel and when. Which way it pulls, the speed where the vibration starts, and any recent pothole or curb contact all help the technician work faster. How often should alignment be checked? There's no single interval for every driver. Follow your owner's guide and the Maintenance Schedule, and add a check after any hard impact or when you see uneven tire wear. Hit a Pothole Lately?
