Why Is My Check Engine Light On?
Seeing the check engine light on your GMC truck or Chevy SUV can signal anything from a simple loose gas cap to a more serious issue like an exhaust system problem. If this light stays on while you're driving, it's crucial to have it checked out as soon as possible at our Mount Vernon service center.
Common Dashboard Warning Lights & Their Meanings
Oil Pressure Light
This light indicates low oil pressure, which can lead to significant engine damage if not addressed quickly. Check your oil level and schedule service if the light remains on.
Battery Alert Light
If this light appears, your vehicle's battery may not be charging properly. This could be due to a faulty alternator, battery or wiring issue. It's important to have this checked to avoid a breakdown.
ABS Light
Tire Pressure Monitoring System (TPMS) Light
This light indicates that one or more tires may be under-inflated. Check your tire pressure and inflate them to the recommended levels to ensure safe driving conditions.
Low Fuel Light
When this light comes on, it means your fuel level is low, and you should refuel soon to avoid running out of gas.
Traction Control/Stability Control Light
This light indicates that your vehicle's traction or stability control system is active, helping to maintain control on slippery surfaces. If it stays on, it may indicate a malfunction that requires attention.
Lights On Reminder
This reminder alerts you that your headlights or other exterior lights are on, which can help prevent battery drain if you forget to turn them off after parking.
Security Light
If this light is illuminated, it may indicate an issue with your vehicle's anti-theft system. This could prevent the vehicle from starting, so it's important to have it checked by a professional.
