Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The push rod failed with no other engine warnings while driving at approx. 65mph. Other problems with this vehicle is that I've put 5 alternators in it, the 5th coming at 79,000 miles. That's not normal; all Pontiac says is tough! Any problems with the engine that they're not telling me? (DOT number: n/a tiresize: n/a)”
NHTSA complaint #736832, filed 2000-11“Consumer purchased vehicle on feb. 14, 2000 from used car dealer. Vehicle was towed to a mechanic who found out that engine was messed up because the rods were shot, 3-7-2000 less than 30 days after purchase. Consumer contacted the dealer. Dealer told consumer that it was bought in the shape it was, and it was consumers porblem.”
NHTSA complaint #858732, filed 2000-03“Am reporting failed engine on 1994 Bonneville for no apparent reason. Have talked to other people who have had rods go out on their engines also and thought maybe someone ought to look into manufacturers liability for producing inferior motor and selling to consumers. Had car in shop 3 or 4 times for a clicking sound and they found nothing up until this last time. Please help on this matter if you can. Don't know who else to contact.”
NHTSA complaint #753203, filed 2001-10“Consumer states while driving the vehicle at any speed and with no warning vehicle got shut off, causing consumer to pull off the road. Dealer has inspected vehicle several times, and could not duplicate or correct the problem.”
NHTSA complaint #10025004, filed 2003-06“Engine fails without warning, car stalls while sitting warming up or traveling with no warning. When engine stalls, can occasionally be restarted.
