Example complaints

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

“At 70,000 miles my engine had a blown head gasket and a cracked head which has cost me a total of $1000.00 for parts and labor. I contacted g.m. And they told me '93 & '92 models were reacalled for this same exact problem, however my car does not have a recall. I feel I should be reimbursed for my cost since my engine problem is identical to the previous recall.”

NHTSA complaint #726629, filed 2000-08

“Motor had a cracked head. Oldsmobile acknowledges faulty head gaskets on 1992 and 1993 models and states they have fixed the problem. The mechanic says that our head gaskets cracked in the exact locations of '92' and '93 models that he repaired. He feels that Oldsmobile did not repair the head in our 1994 achieve that was built in november 1993. We believe that Oldsmobile needs to extend their coverage to include 1994 models.”

NHTSA complaint #735575, filed 2000-11

“Cracked engine head caused antifreeze leakage, car sputters. Had to be replaced at a cost of $450 for the head core, excluding labor and additional costs. It has come to my attention that this is a common problem and that some dealers are getting this part at no cost for replacement. Would like to be reimbursed for at the very least the cost of the head core unit!”

NHTSA complaint #705158, filed 1999-03

“The vehicle cut off as the consumer was driving into the driveway. The consumer took the vehicle to the dealer regarding the recall notice received on 12/2001 (00v-287). The dealer said the motor needed to be replaced.”

NHTSA complaint #561210, filed 2001-05

“Engine lost power at 65 MPH on freeway, able to pull to right shoulder, engine was not hot, no check lights were on, checked oil & water levels, ok, tried to restart engine but it was very noisy & backfiring, and would only run at fast idle. Shut down, called tow truck. Mechanic took a compression check, no compression in # 2 & 4 cylinders. This engine has a timing chain, not a belt, timing was checked, found ok. Pulled head & found that valves on those cylinders had hit pistons, but not enough to hurt same. …”
