Two problems related to rearview system braking have been reported for the 2020 GMC Terrain. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 GMC Terrain based on all problems reported for the 2020 Terrain.
Backup camera stopped working and displays a blue screen stating “service backup camera. ” this was an issue when the vehicle was under 3 year manufacturer bumper to bumper warranty and was fixed by dealer at no cost. Now this same issue has occurred again approximately 3-4 years later. I thought at first this was an issue specific to my vehicle but now after doing research I see this is an issue across several GMC terrian vehicles and other gm vehicles. This issue should be fixed by the manufacturer for all vehicles affected. Vehicle owners should not be responsible to fix faulty parts from the manufacturer.
None of these features have ever worked.
