Two problems related to wiper 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.
Vehicle has 56801 miles and air conditioning completely went out. I have also replaced windshield wipers twice in 6 months. This is more than any other vehicle I have ever owned (I have had the vehicle 1 year now).
I am a male of 6'1" height and find it very hard to see out the rearview mirror when I drive my wife's GMC Terrain. Because of the limited mobility of the mirror, I am unable to see other cars behind my vehicle without lowering my head and reclining my seat backwards, both of which can be very dangerous to do while driving. I would like to see the mirror adjusted to be longer, or able to be adjusted further upward to improve visibility for taller people, like myself.
