Example complaints

“I went out one morning and started my truck and heard a rattle noise coming from the engine. I got out and opened the hood. Almost instantaneously the engine backfired and the cooling fan blew apart and fragments of metal came through the plastic shroud and into my face and head causing serious and would have been fatal injury to myself. If it were not for the fast response of the paramedics who flew me to the hospital by chopper. I am now blind missing an eye and my face and head are scared along with possible brain damage. …”
NHTSA complaint #10531539, filed 2013-07, 210,000 miles“The windshield wipers will stop in mid stroke and stay there for an extended period of time before resuming. Newer models have been recalled, but the '93 Gmc has always had the same problem. The EGR valve tends to stick open. It has been cleaned and/or replaced several times, and it's a safety issue because it drastically lowers manifold vacuum and that effects the power brakes.”
