Certain parts of your car wear down over time, including the brake pads. When those get too thin, you'll start experiencing problems with braking, so it's important to get new brake pads as soon as your car shows you that you need them. You can get replacement brake pads and all other forms of brake service at your local GMC dealership. more 1. Your Brakes Get Screechy You shouldn't hear anything when you brake normally, but you will if your vehicle has exposed brake pad wear indicators. These indicators are built into the brake pads to tell you when it's time to replace them. The indicators are made of metal, so when they press against your rotor, you'll hear a metallic screeching or squealing sound. 2. Your Brake Pedal Vibrates Braking should only cause vibrations if your ABS brakes engage. Under normal circumstances, the pedal should never vibrate or pulsate. If it does, then it probably means your rotors are damaged. This can be caused by brake pads that have worn down too much, so there's metal-on-metal contact happening, damaging your rotors in the process. 3. Your Brakes Start Grinding We've mentioned that there's often a wear indicator built into your brake pads. This will continue to cause the screeching noise we discussed until you get new pads. However, if you don't get new pads, then the sound could get worse and sound more like a growling or grinding. This typically means the brake pad has completely worn away, and now your calipers are in contact with the discs. 4.  Your Brake Pads Are Visibly Thin Giving your car a once-over every few weeks may help you catch issues before your car starts having problems. One thing you might notice is thin brake pads. The pads should be at least one quarter of an inch thick, though thicker is better. You'll be able to see the brake pads by looking through the spokes of your wheels. Get your brakes inspected if the pads are looking a little thin. 5. Your Brake Pad Light Comes On Many GMC vehicles have a light that turns on specifically when the brake pads need to be replaced. This differs from the check engine light or ABS light you may be familiar with. The only thing it tells you is that the brake pads need to be replaced. Once you get new pads, you'll need to reset the Brake Pad Life Monitor through your vehicle's cluster display. Do you need your brake pads replaced or another form of service for your car? Come get it all done at Marquardt of Barrington GMC in Barrington, IL.

An all-electric powertrain, bidirectional charging, and 4-Wheel Steer are some of the innovative features you will find in the 2025 GMC Sierra EV. The full-size pickup truck comes equipped with tremendous horsepower and a long list of technologies to tackle jobs both on and off the pavement. more All-Electric Powertrain The heart of the GMC Sierra EV is an all-electric propulsion system that generates 645 hp and 785 lb-ft of torque. It incorporates two electric motors, with one positioned on each axle, and an Extended Range battery. Choosing the available Max Range battery increases the power output to a formidable 760 hp, making the truck quicker and giving it extra muscle for the worksite. In this configuration, the Sierra EV hits 60 mph in 4.5 seconds and tows 10,500 lbs. Although there are many all-electric pickup trucks on the market, only a few come close to matching the driving range of the Sierra EV. The standard Extended Range battery allows the pickup truck to drive an impressive 390 miles on a single charge. With the Max Range battery, the Sierra EV's driving range reaches an incredible 460 miles. Bidirectional Charging The electric pickup truck has access to approximately 250,000 public chargers, which include Level 2 and DC chargers. You can locate the nearest station or plan a charging stop along your route using the myGMC mobile app. When plugged into an 800V DC Fast Charger, the Sierra EV gains up to 100 miles of electric range in 10 minutes, allowing you to continue your haul after a short break. You can also charge the Sierra EV at home with a GM Energy PowerShift charger. Adding a vehicle-to-home (V2H) enablement kit to the system lets you harness the pickup truck's bidirectional charging capabilities. The Sierra EV is capable of powering your home for up to 21 days during a blackout. Revolutionary Off-Road Technology You can confidently drive deep into the wilderness thanks to the Sierra EV's traction-rich eAWD system, 8.95 inches of ground clearance, and adaptive air suspension with adjustable ride height. With the press of a button, drivers can increase the truck's ground clearance to put extra distance between the underbody and rugged terrain. The pickup truck also features a host of other innovative off-road technologies, such as 4-Wheel Steer and CrabWalk. 4-Wheel Steer enables you to make extremely tight maneuvers by turning the rear wheels in the opposite direction to the front ones. CrabWalk, on the other hand, turns all four wheels in the same direction, allowing the truck to move diagonally. Dominate your next job with the GMC Sierra EV's all-electric powertrain and innovative technology. Contact us at Marquardt of Barrington GMC in Barrington, IL to find out how you can make the pickup truck yours.

The 2025 GMC Canyon is built with versatility in mind, containing a selection of features that help it thrive on all terrain.

StabiliTrak StabiliTrak is an electronic control system that will help you keep your GMC Canyon under control in unpredictable driving situations.

It's powered by the truck's sensors, which can detect differences between the vehicle's movement and the intended direction of travel. 3. ProGrade Trailering System The ProGrade Trailering System is an app-based feature which comes as standard on the GMC Canyon, offering drivers a selection of digital tools to make towing a lot simpler. These tools include hitch guidance, to help you attach the trailer to your truck. 4. HD Rear-Vision Camera The extended length of trucks such as the GMC Canyon can make backing up tricky. Thankfully, with the Canyon's HD rear-vision camera, you'll have a clear view of the surroundings behind you, displayed on the interior display screen. The images will appear when the back tailgate is in the raised position and the vehicle is in reverse. 5. 11-Inch Diagonal Driver Information Center With the sizable driver information center, you're unlikely to miss a single piece of useful information when driving. The full-color HD screen will display alerts and vehicle information, including speed, engine temperature and fuel levels. The screen is customizable, meaning you can decide the information that you want to be most prevalent on the screen. 6. Lane Keep Assist When driving on the highway, it can be easy to accidentally drift to the side of the lane, rather than maintaining a central position. The Canyon's Lane Keep Assist feature will be able to sense when this is happening, nudging the steering wheel slightly to get you back into the middle of the lane. The feature works by analyzing the road markings with the truck's forward facing camera. With a priority on versatility and safety features, the new GMC Canyon can flourish up a rugged hill with the same ease as it can on a tarmac road. Think it may be the right option for you?

If you want to drive the latest edition of a GMC truck, SUV, or van, leasing could be your best option. Read on to learn all the leasing benefits to be enjoyed at your local GMC dealership. more Save Money Upfront On the day of drive-off, you save a lot when you lease. With a traditional loan, you're facing a sizable down payment of up to twenty percent of the truck's full value. With a lease, your initial costs are usually a fraction of that, making it a far more affordable way to start driving a new GMC. Reduce Your Monthly Costs Your monthly cashflow may also hugely benefit with a lease arrangement. As the total value of the lease is only the amount by which the vehicle depreciates during the lease term, your monthly costs are going to be far lower than with a normal loan. Cheaper Vehicle Maintenance As you're leasing a new vehicle, it will usually be covered by a robust warranty that pays for routine maintenance. This can amount to another significant reduction in costs over the year. And if you continually lease your truck (or trucks), you'll always be protected by a warranty. Afford a Larger, Better Truck If the perfect GMC vehicle is currently out of your price range, leasing may enable you to reach it. Many drivers and businesses use leasing to afford higher-end vehicles that can carry out hauling and towing tasks even more effectively, all without breaking the bank. Enjoy the Latest Features GMC is consistently at the cutting edge of tech when it comes to trucks, SUVs, and vans. As leasing allows you continual access to brand-new editions, you can always enjoy the very latest features and driver assist technology. Return the Vehicle Easily Once the lease term ends, returning the vehicle is far easier with leasing. Rather than trying to find a buyer, you simply take your leased vehicle back to the dealership and that's that. And in many cases, if you'd rather keep the truck, you have the option to buy at the end of the lease if you decide that's the best course of action. Find Out Your Personal Leasing Benefits at Your GMC Dealership We'd be happy to talk you through your leasing options and compare leasing in more detail to buying. Once you realize the financial and flexibility benefits, you're likely to become a big fan of leasing, as so many other truck, SUV, and van drivers are. Get behind the wheel of your dream GMC today at Marquardt of Barrington GMC in Barrington, IL. We've been providing the region's drivers with terrific vehicles and deals since 1950.

Your car's ignition coil is a vital piece of your engine, working to convert your battery's power into the voltage needed to create an electric spark. When it isn't working properly, it can affect your car's performance. Here are some signs you need to get it checked out at the GMC dealer. more 1. Engine Misfires One of the most common signs that something is wrong with your ignition is engine misfiring. This can feel like a stutter or hesitation when you attempt to accelerate or an overall rough and irregular engine rhythm when idling. Misfires happen when there isn't enough voltage going to the spark plugs to ignite the air/fuel mixture properly. 2. Sudden Loss of Power Does your car feel weaker than usual? If you have a faulty coil, your vehicle can feel like it's struggling to maintain power, especially when accelerating. This may be particularly obvious under heavy loads or while climbing hills. 3. Poor Fuel Economy Poor performance from your ignition can cause your vehicle's fuel efficiency to decrease noticeably. This is because the incomplete combustion caused by faulty coils requires your engine to burn more fuel to produce the same amount of power. Keep an eye on your fuel consumption. If you're making more trips to the fuel pump despite your driving habits staying the same, it could point to a problem with your coils. 4. Difficulty Starting Another indication of a potential coil issue is having difficulty starting the vehicle. A failing coil may struggle to generate the necessary voltage for an initial spark, making the engine take longer to start or requiring several attempts to get going. 5. Check Engine Light The check engine light can activate for numerous reasons, but one common cause is issues with the ignition system, including the coils. Modern vehicles are equipped with an onboard diagnostic system that triggers the check engine light when it detects irregularities in the ignition process. Using a diagnostic scan tool can confirm whether the problem is related to the ignition. 6. Engine Backfiring Have you heard loud popping noises from your car? It could be backfiring. Backfiring happens when unburned fuel exits the engine into the exhaust system, where it ignites. Faulty coils can cause backfires by failing to ignite the fuel at the right time, leading to fuel buildup in the exhaust system. 7. Rough Idling If there's a problem with your coils, your engine may idle unevenly, producing a rough or jittery idle as the engine misses regular power strokes. This uneven performance can be particularly noticeable when you are stopped at a traffic light or when the engine is first started. Visit Your GMC Dealer to Check Your Coils If you suspect the coils in your ignition are faulty, you should visit your local dealership for a thorough inspection. Our certified technicians can accurately diagnose those issues and provide any needed replacements. Having trouble with your ignition? Don't wait. Visit Marquardt of Barrington GMC in Barrington, IL, to get your ignition inspected right away.

The 2025 GMC Acadia holds its own in the highly competitive mid-size SUV segment, boasting an opulent feature-packed cabin, head-turning looks, and adult-friendly seating in all three rows. It also handles well for its size and delivers a smooth ride. Let's dive deeper into the incredible features this luxury SUV has to offer. more 1. Comfort and Convenience The spacious and well-designed interior of the 2025 Acadia is ready to comfort you and store everything you need for your commutes and road trips. You'll get 23 cubic feet behind the third row, 57.3 cubic feet behind the second row, and a whopping 97.5 cubic feet with both rear seats folded. Heated driver and front passenger seats help provide warmth during cold months, and the tri-zone automatic climate control keeps all passengers comfortable with individualized climate settings. A 15-inch GMC infotainment system with Apple CarPlay and Android Auto integration ensures seamless smartphone connectivity. An 11-inch diagonal driver information center provides key information about your car, including speed, fuel range, and warning messages. Owners will also love the active noise cancellation technology that helps leave outside noise where it belongs. 2. Power and Performance Under the hood of every new Acadia, you'll find an energetic and efficient 2.5-liter inline-four powertrain that yields up to 328 horsepower, paired with an 8-speed automatic transmission. Four-wheel antilock disc brakes prevent the wheels from locking up during braking, enhancing control and reducing skidding. Automatic stop-start technology shuts off your engine when the vehicle is stationary and restarts it when you release the brake pedal, helping to improve fuel efficiency. The fully independent suspension is tuned to ensure smooth rides and optimum handling. There's also the heavy-duty cooling system that helps the engine dissipate heat to avoid temporary overheating during adverse operating conditions. 3. Driver-Aid Systems The new Acadia comes equipped with a myriad of sophisticated driver-assist features to improve your safety and confidence on the road. Enhanced automatic emergency braking, forward collision alert, and blind zone steering assist are some of the features that work hard to prevent collisions. The HD surround vision ensures drivers are aware of everything happening around their vehicle, and the hitch view shows a close-up view of the trailer hitch. Lane keep assist and lane departure warning are also standard, as are rear cross-traffic braking, safety alert seat, and traffic sign recognition. With a maximum trailering capability of up to 5,000 pounds, the new Acadia is ready for all your family adventures. The traction control select system allows drivers to switch from up to six drive modes to tailor their ride to differing conditions.

Regular maintenance ensures your vehicle always provides peak performance. As your GMC dealership, we'd like you to know some signs you need to visit for vehicle maintenance. more Check Engine Light Your GMC contains numerous sensors, each of which is connected to an important component. The sensors receive instructions from the computer and transmit information back to it. They also inform the computer of any problem with their connected component. If something goes wrong and the computer can't correct the issue, it logs the problem with an error code and illuminates the relevant warning light on your dash. The check engine light illuminates in response to any issue affecting engine performance. It also lights up if something goes wrong with the transmission, as the engine and transmission work together to move your vehicle. A blinking engine light highlights an issue like misfiring, while a solid engine light means a major engine problem. Our technicians will investigate and repair the problem. Gas Smell You should never smell gas around your vehicle except possibly briefly if you've you just visited the gas station. The fuel system is sealed for safety and to prevent air from entering and forming air bubbles that could block the system. Air would also reduce the system pressure, leading to reduced performance. If you smell gas, it's time to visit our service department ASAP so we can find the problem. Damage to the exhaust manifold, the section of the exhaust that connects to the cylinder exhaust vents, will cause fuel vapor to leak and enter your cabin. A loose or damaged fuel cap or a fuel-rich engine will also produce a strong fuel smell. All these issues will also reduce vehicle performance. We'll find the cause of the problem, and the fuel smell will disappear as soon as we fix it. Rattling Noises Strange rattling noises under your vehicle mean something is loose. Two possible sources of this noise are a broken exhaust hanger or a severely damaged catalytic converter. The exhaust system is held in position by hangers. In time, rust or other damage can cause a hanger to break. This allows the affected exhaust section to move slightly, and it will bang against the underside of your vehicle until we replace the hanger. The catalytic converter changes dangerous engine gases into harmless ones using intense heat, crushing pressure, and chemical reactions. A worn converter can overheat, and excessive temperatures can cause the honeycomb interior to crack. Cracks will spread, and parts of the honeycomb will break off and rattle inside the converter. We can't repair this damage, but we'll replace the converter. When you need maintenance, contact the experts at Marquardt of Barrington GMC in Barrington, IL.
