Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The transmission has been shifting rough since the vehicle was purchased new in 1991. The first incident was covered under warranty and some minor repairs/adjustments were made by the dealer. The second incident required more extensive repairs to the transmission and I was required to pay a portion of the repairs since the warranty had expired by some 2-3k miles. Upon the third incident with the drive train, I requested someone from the manufacturer to investigate. They requested that I keep a log for about two weeks of the conditions occurring while driving. …”
