Does Your Buick or GMC Vehicle Need an Alternator?

Alternator

Whenever you're on the road, your vehicle's alternator uses the engine's power to generate electricity for the battery and other components. If an alternator malfunctions, the other electrical parts are never far behind. Here are some common warning signs that your car is in need of immediate alternator repair at your local GMC dealership.

Does Your Buick or GMC Vehicle Need an Alternator Repair?

Trouble Starting the Engine

Have you tried to turn on your car's engine and only heard a clicking sound, without a response from the engine? When a car fails to start, unless the starter itself is faulty, the battery may be dead because of a bad alternator. Try jump-starting your car; if the engine keeps going, your alternator is probably fine and your battery might have died for some other reason. 

Repeatedly Dying Battery

The battery depends on the alternator for all of its power. So if your battery keeps failing to recharge properly, either your battery is too old or your alternator is malfunctioning. You may need to have a technician diagnose the problem. 

Faint or Flickering Headlamps

If your vehicle's headlamps rapidly fade in brightness, your alternator may be to blame. If the light ahead of your car begins to flicker, the supply of voltage may be fluctuating as the alternator dies. 

Problems With Several Accessories

With a failing alternator, all of your car's electronics will also suffer. Modern cars often have a prioritization system in place in the event of an electrical supply issue. This means your nonessential accessories such as the stereo and heated seats will lose power before the headlamps and spark plugs. 

Smell of Burning Wiring

When the wiring in or connected to an alternator becomes damaged, it can cause resistance to the flow of voltage. This might cause overheating and an electrical fire, in which case you may smell something burning. An overloaded alternator might sometimes also cause burning wiring by pushing excessive voltage through the wires.

Blinking Alternator Light

Some vehicles have an "ALT" warning light that appears on the dashboard when an alternator fault is detected. Alternatively, you may see the battery warning light appear. Neither of these warning lights should be ignored, as the electrical supply is vital to the proper functioning of any modern car. 

Replace Your Alternator at Your GMC Dealer Every Seven Years

Alternators are hardy car components that usually last from 80,000 to 150,000 miles. The average driver will have to replace their alternator about once every seven years. If you're lucky, your faulty alternator may be repairable with the help of a skillful technician.

Celebrating National Seat Belt Day on November 14th

Every year on November 14th, we observe National Seat Belt Day to remind ourselves and others of the life-saving power of a simple buckle. This day is not only an opportunity to acknowledge the historical significance of seat belts but also to spread awareness about their continued importance in ensuring road safety. Why National Seat Belt Day Matters National Seat Belt Day, established in 2019 by the Governors Highway Safety Association (GHSA), Uber, and Volvo, serves as a reminder that the three-point seat belt, invented by Nils Bohlin in 1959, remains one of the most effective safety innovations in the history of automobiles. Despite its simplicity, this invention has saved countless lives and continues to be a critical component in vehicle safety. Often overlooked, the seat belt is a humble hero of road safety. Consider these compelling statistics: seat belts reduce fatalities by 45% among front-seat passengers and drivers, prevent serious injuries by 50%, and are an essential complement to airbags, which can be dangerous if passengers aren’t restrained by seat belts. How to Observe National Seat Belt Day Buckling up every time you get into a vehicle is a simple yet crucial action for your safety. By wearing your seat belt consistently, you can significantly reduce the risk of injury. Be a role model and encourage those around you to do the same, ensuring all passengers are properly buckled up, whether it's a short drive or a long journey. Spread awareness about the importance of seat belts through conversations and social media. Share stories, statistics, and experiences to emphasize why buckling up is vital. Educating children on this habit can lead to lifelong safety practices. Engage them with activities like the Buckle Up Buddy Heart craft and Ride Safe activity sheet to teach road safety effectively. The History of Seat Belts Use The history of seat belts is a testament to progress in automotive safety. From the first patent by Edward J. Claghorn in 1889 to the mandatory inclusion of seat belts in all U.S.-manufactured vehicles by 1968, the evolution of seat belt usage reflects a growing commitment to protecting lives on the road. Despite initial resistance, where critics argued that seat belts might trap passengers during accidents, the evidence soon proved otherwise. By 1968, seat belts were a federal requirement, and their use has been steadily increasing, with the national usage rate rising from 58% in 1994 to nearly 92% in 2023. Fast Facts About Seat Belts Influence on Youth: Children whose parents use seat belts are more likely to buckle up themselves. Rural vs. Urban: Despite assumptions of safety, rural areas often see higher rates of unrestrained fatalities. Back Seat Safety: Rear-seat passengers must also buckle up to ensure maximum safety during a crash. Buckle Up, Every Time, Everywhere! National Seat Belt Day is more than just a date on the calendar; it's a call to action. It’s a reminder that we hold the power to protect ourselves and our loved ones with the simple act of buckling up.

How to Prepare Your Buick or GMC for Seasonal Changes: A Comprehensive Guide

Regular Buick maintenance or GMC maintenance replaces worn or damaged components that reduce vehicle performance. The various seasons place additional demands on your vehicle, and as your Buick and GMC dealer, we want to tell you some of the specialized maintenance we offer for each season. more From Your Dealer: Buick Maintenance and GMC Maintenance for Each Season Spring Our Texas summers get hot, and you need your trusty AC to deliver cold air on demand. We ensure the belts are in good condition, the AC is oiled, and we test the compressor, condenser, and other systems to make sure they're working properly. We also check for system leaks and that the refrigerant level is full. Spring is also the time to check the wiper blades and replace them if necessary. The rubber blades lose flexibility over time and can crack and break. Damaged blades scrape against the windshield and can cause scratches that lead to cracks. In addition, worn blades won't be cleaned correctly, leaving smears that reduce visibility. Summer The engine works most efficiently between 185 F and 220 F, but the heat generated by combustion makes it even hotter. A cooling system service is vital to keep that temperature under control. We examine your radiator, hoses, and all other components and replace worn parts. We also top up the coolant or replace it as necessary. The heat also increases your tire pressure, and overinflated tires suffer increased center tread wear that can cause leaks or a blowout. Tire pressure increases naturally by 1 to 2 PSI per 10 degrees of temperature. We'll readjust the tire pressure to help prolong tire life. Fall It's time to test your battery before winter arrives. While it's not cold enough in El Paso, TX to cause the electrolyte to freeze, lower temperatures can still weaken an already worn battery, causing it to fail. We hook your battery to our computerized battery tester to identify any weaknesses and gauge the battery's remaining life. If your battery is failing, we'll replace it. Winter The longer, darker nights mean your headlights must work correctly. If the bulbs look dim, it's time to change them. Bulbs have a lifespan ranging from 500 hours to 30,000 hours but can fail sooner. We'll also check the headlight lenses are clear and scratch-free, as damaged lenses reduce headlight visibility when you need them the most.
