GMC is a great brand known for reliability, comfort, style, and performance. In our experience, some customers have had a few issues like the spark plugs. A spark plug acts as a seal in the combustion chamber and provides the gap for the spark that causes combustion in the engine. It is recommended to replace spark plugs about every 30,000 miles. There is no way to prevent plugs from failing. It just happens over time. Faulty air flow sensors are another known issue that comes up time and again. This sensor tells the computer in your vehicle to add the correct amount of fuel based on the air that is coming into the engine. When an airflow sensor starts to fail, the car will stall, idle poorly, the emissions will go up, and your gas mileage will drop. It is possible to drive with a malfunctioning airflow sensor, but it's not  good for your car.

Well once again Glenn and the crew at Foothill Auto Service come through with shining colors! My wife drove our car to work and said there was fluid leaking out when she parked (and took a picture send it to me that looked pretty serious). It looked like a lot of fluid so I went down to pick up the car and got it to Glenn to check it out. Glenn got back to me within a few hours and told me there’s no worries the car is just fine just a little excessive condensation coming out. No charge -and the confidence knowing my car is just fine for my wife to drive and not get stranded somewhere. Thank you so much Glenn for your awesome service and great way that you deal with customers. -- Kent C
