Steady vs. flashing check engine light on two dashboard gauges

Is It Safe to Drive With the Check Engine Light On?

If the check engine light is steady and your vehicle drives normally, you can usually keep driving, but get it checked soon. If the light is flashing, ease off, and if it keeps flashing, pull over safely and call for service. The check engine light is one of the most common reasons drivers around Hammond and the Northshore call our service department. The good news: a lit check engine light is not always an emergency. The key is knowing the difference between a steady light and a flashing one. Steady vs. Flashing Check Engine Light Steady light Flashing light What it usually means The engine computer has detected a problem that isn't usually urgent, such as a loose gas cap or a sensor issue Often a severe engine misfire, which can overheat and damage the catalytic converter Can you keep driving? Usually, if the vehicle drives normally Ease off. If it keeps flashing, pull over safely and call for service How soon to get it checked Soon, before a small problem becomes a bigger one Right away Pull Over Right Away If You Notice Shaking or rough running A loss of power A burning smell Smoke Overheating (temperature gauge climbing or a temperature warning) Any of these along with a check engine light is a sign to stop driving. Find a safe place to pull over, turn off the engine, and call for service or roadside assistance. What to Do When the Check Engine Light Comes On Notice whether it's steady or flashing. That tells you how urgent it is. Check how the vehicle feels. If it drives normally, you can usually continue. If anything feels off, reduce speed and load. Make sure your gas cap is tight. A loose or worn cap is a common, easy fix. The light may take several drives to go off after you tighten it. Have the code read and the problem diagnosed. A diagnostic code points a technician in the right direction, but it doesn't always name the exact failed part. A proper diagnosis does. Check your owner's manual. Warning lights and recommended steps can vary by vehicle. Common Causes of a Check Engine Light Loose, damaged, or missing gas cap Oxygen sensor issues Spark plugs or ignition coils, which can cause misfires Evaporative emissions (EVAP) system leaks Mass airflow sensor problems Catalytic converter problems, often a result of another issue left unrepaired Even a steady light can point to a problem that gets worse, and more expensive, the longer you wait. Getting it checked early is usually the simplest and most affordable path. Check Engine Light FAQs Can a loose gas cap turn on the check engine light? Yes. A loose or worn gas cap can let fuel vapor escape, and the vehicle's emissions system may flag it. Tighten the cap until it clicks. The light may stay on for several drive cycles before it turns off. If it doesn't go off, have it checked. Will the check engine light turn off by itself? Sometimes. If the condition that triggered it goes away, the light may turn off after several drives. Even then, a diagnostic code may still be stored in the vehicle's computer, so it's worth having it read if the light came on more than once. Is a flashing check engine light worse than a steady one? Yes. A flashing light often means a severe misfire, which can damage the catalytic converter. Ease off, and if it keeps flashing, pull over safely and call for service. Does reading the code tell you exactly what's wrong? Not always. A code tells a technician which system reported a problem, but the root cause can take testing to confirm. That's why a full diagnosis matters before replacing parts. Check Engine Light On? We're Here to Help. Questions about your GMC or any vehicle? Ask the service team at Ross Downing GMC Hammond.

Is Synthetic Oil Worth It If You Tow With Your GMC?

Is Synthetic Oil Worth It If You Tow With Your GMC?

Is Synthetic Oil Worth It If You Tow With Your GMC? For most newer vehicles, yes. Synthetic oil is worth it, and many newer engines call for it. If you pull a boat, camper or work trailer with your Sierra or Yukon, your engine oil is working harder than you might think. Here's what our Hammond service team wants you to know. Towing, heat and your oil Towing adds load, and load adds heat. In south Louisiana summers, that heat builds fast. Synthetic oil holds up better under those conditions and resists breaking down. Some owner's manuals also list a separate maintenance schedule for heavy use like towing, so it's worth checking which one applies to you. Why synthetic oil is worth it It holds up in high heat. Synthetic oil resists breaking down when your engine runs hot, which matters in south Louisiana summers. It flows easily at startup. It helps protect engine parts in the first few seconds after you start the car. It helps most under hard use. Towing, stop-and-go traffic and turbocharged engines all make your oil work harder. What to do Check your owner's manual for the oil viscosity and specification your engine calls for. Follow your oil life monitor if your vehicle has one, and don't go past it. Ask our service team if you're not sure which oil is right for your vehicle. Frequently asked questions Should I change my oil sooner if I tow? Follow your oil life monitor, which accounts for how you drive, and check your owner's manual for any severe-service or towing schedule. Our service team can help you read it. Is synthetic oil worth it for a Sierra? Many newer GMC engines call for a specific oil that meets GM's specification. If you tow or haul, synthetic's extra protection under heat helps most. Your owner's manual lists the exact oil. Can I use synthetic oil in an older vehicle? In many cases, yes, as long as the oil meets the viscosity and specification in your owner's manual. If you're not sure, ask our service team. Can I switch between conventional and synthetic oil? Generally yes, as long as the oil meets your owner's manual specification. Mixing oils that meet the specification generally won't harm your engine, but you'll get the most benefit from the type your manual recommends. Time for an oil change? Ross Downing GMC · 1301 S.

New vs Used SUV Comparison for Gonzales GMC Shoppers

New vs Used SUV Comparison for Gonzales GMC Shoppers

A new vs used SUV comparison can start with one simple question. How much vehicle history are you comfortable taking on? A new GMC starts with zero prior owners and full factory coverage. A CarBravo GMC has prior mileage, yet it also passes a formal certification process. Therefore, the decision reaches beyond sticker price alone. Warranty structure, depreciation, financing, mileage, and planned years of ownership all deserve attention. What Does CarBravo Include? CarBravo is GM's certified used vehicle program. It adds inspection, history information, warranty coverage, roadside assistance, and transportation support to eligible used vehicles. Therefore, it sits in a different category from an ordinary used vehicle listing. Every CarBravo vehicle receives a multipoint inspection from a Certified Service technician. Vehicles under 10 model years old with fewer than 100,000 miles receive a 126 point inspection. CarBravo also provides a free CARFAX Vehicle History Report. GM requires participating dealers to complete open safety recalls before listing or selling the vehicle. Those steps give shoppers several items to review before purchase: CarBravo certification includes a technician inspection focused on key parts and vehicle operation. A free CARFAX Vehicle History Report gives prior use and reported history details. Eligible vehicles receive limited warranty coverage, roadside assistance, and transportation support after purchase. Certification does not make every used GMC identical. Mileage, prior use, trim, condition, and service records can still vary from one vehicle to another. Therefore, each CarBravo GMC still deserves its own review. How Does New Vehicle Depreciation Change the Math? A new vehicle starts losing market value from its original new vehicle price after purchase. That early value change can represent a larger share of depreciation during the first years. A used GMC has already moved through part of that period before the next owner purchases it. That does not mean every used GMC will hold its value at the same rate. Model demand, mileage, condition, equipment, and market pricing all play a role. Still, depreciation should remain separate from the amount paid at signing. Consider the timing of your purchase and the years you expect to keep the SUV. A new GMC may offer more years before age and mileage climb. A CarBravo GMC may lower the amount tied up in the initial purchase. Therefore, the more useful comparison looks at purchase price and future value together. A lower price today can change how much depreciation remains ahead. A higher new vehicle price may pair with more factory coverage and zero prior mileage. How Warranty Coverage Differs New GMC and CarBravo warranty coverage should not be treated as the same product. Each path starts from a different point in the vehicle's life. New GMC vehicles registered in the United States include bumper to bumper limited warranty coverage. That coverage lasts 3 years or 36,000 miles, whichever comes first. GMC also lists a 5 year or 60,000 mile powertrain limited warranty for most current models. Certain engines and vehicle classes can use different terms. Eligible CarBravo vehicles under 10 model years old and below 100,000 miles receive separate certified used coverage. CarBravo lists a 12 month or 12,000 mile bumper to bumper limited warranty with no deductible. Coverage terms can interact with any remaining original factory warranty. Before choosing either path, compare the exact coverage attached to the specific vehicle. Review: The date when bumper to bumper coverage ends. The mileage limit attached to each warranty. Any remaining factory powertrain coverage. The CarBravo limited warranty period tied to the certified used vehicle. A newer CarBravo GMC may still carry part of its original factory coverage. An older certified vehicle may rely more heavily on the CarBravo warranty. Therefore, vehicle age and in service date matter during this comparison. Mileage Inspection and Vehicle History Mileage changes the context around a certified used GMC. A vehicle with 15,000 miles presents a different history than one approaching 90,000 miles. The certification process adds inspection, but the odometer still tells part of the story. The CARFAX report can show reported ownership changes, service records, and other recorded events. However, shoppers should pair that report with the physical inspection and dealer records. No single document tells every detail about prior use. Look at tire condition, brake condition, service history, interior wear, and remaining warranty time. Also review whether the trim includes the equipment you want. A lower purchase price can lose appeal if the SUV lacks features you planned to use. The same review applies across the GMC lineup. A Terrain, Acadia, Yukon, or other GMC can make sense through CarBravo when its history fits your plans. Financing and Monthly Cost Financing deserves its own comparison because purchase price does not create the monthly payment by itself. Rate, loan term, down payment, incentives, taxes, and financed amount all shape the final number. New GMC models may qualify for finance programs or incentives that do not apply to used inventory. CarBravo vehicles may start from a lower purchase price, yet used vehicle rates can differ. Therefore, compare complete loan offers instead of comparing sticker prices alone. Before signing, place these figures side by side: Vehicle selling price after applicable incentives. Down payment and trade value applied to the transaction. Annual percentage rate and total loan length. Estimated total paid across the full loan term. This view can reveal a result that the sticker price hides. A lower used price may still carry a different rate. A new GMC may cost more upfront but qualify for another financing structure. Choosing Based on How Long You Plan to Own the GMC A new vs used SUV comparison becomes clearer once you choose an expected ownership period. Time changes the importance of warranty coverage, mileage, depreciation, and financing. A shopper planning several years with the same vehicle may care about starting mileage and remaining warranty time. Someone focused on lowering the initial purchase amount may place more weight on CarBravo inventory. Neither path needs to fit every household. Start with the vehicle itself. Compare mileage, service history, warranty dates, trim equipment, and final financed cost. Then look at the years you expect to keep it. A new GMC gives you a fresh ownership starting point with full new vehicle coverage. CarBravo gives you a certified used path with inspection, history information, and separate warranty protection. Ross Downing GMC can show both paths side by side so you can compare the numbers tied to each vehicle. You can also browse new GMC inventory before your visit.
