Common Reasons for Remote Start Failure

Remote start systems in GMC Terrains can sometimes malfunction due to various reasons. Here are the most common issues and their solutions:

Dead Key Fob Battery

A weak or dead battery in your key fob is often the culprit. Replace the battery with a new CR2032 lithium coin cell to resolve this issue.

Improper Starting Procedure

Ensure you're using the correct procedure:

  • Lock the vehicle first
  • Press and hold the remote start button for at least 2 seconds
  • Wait for the turn signals to flash

Vehicle Not in Park

The remote start system will only work if the vehicle is in Park. Double-check your gear position before attempting to start remotely.

Hood Not Fully Closed

An open or unlatched hood will prevent remote start. Ensure the hood is completely closed before attempting to use the remote start feature.

Low Fuel or Battery

If your fuel level is too low or the vehicle's battery is weak, the remote start may not function. Refuel your vehicle or charge the battery if necessary.

Technical Issues Affecting Remote Start

Check Engine Light

If the check engine light is on, the remote start system will be disabled. Have your vehicle diagnosed and address any underlying issues.

Valet Mode Activated

Some GMC Terrains have a valet mode that disables remote start. Consult your owner's manual to learn how to deactivate this mode.

Faulty Hood Latch Sensor

A malfunctioning hood latch sensor can prevent remote start. If you suspect this issue, have it checked by a professional.

Recent Repairs or Modifications

If you've recently had body work or electrical repairs, it might have affected the remote start system. Consult with the repair shop or a GMC dealer.

Troubleshooting Steps

1. Replace key fob battery

2. Verify proper starting procedure

3. Ensure vehicle is in Park

4. Check hood closure

5. Inspect fuel level and vehicle battery

6. Address any check engine lights

7. Deactivate valet mode if enabled

8. Have hood latch sensor inspected

9. Consult with recent repair technicians

If these steps don't resolve the issue, it's best to contact your local GMC dealer for a thorough diagnostic of your remote start system.
