Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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.”
