Big thank you to the service department at Mark Wahlberg
Big thank you to the service department at Mark Wahlberg Chevrolet! I was in Columbus traveling 500 miles from home when the tire pressure light on my 2018 Silverado came on with a zero pressure indicator. The guys in service were empathetic to my situation and immediately started inspecting the tires and checking the sensors. Turns out the tires were fine. One of the sensors had gone bad. I had peace of mind to drive home eastern PA. I asked what I owed and was told no charge, glad they could help. Thanks again.
There are 4 matching cars close to your year range.
