“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

“I purchased this vehicle new. Within 6mo the first alternator problem occurred. In the past 8years I have had 10 alternators and 4 batteries put in the vehicle. Everytime the battery guage would go low when checked I was told that the problem was the alternator. On one occassion I took my car due to the fact the dealer was closed, to another car repair shop who replaced the battery but stated there is an electrical problem and until that is fixed I will still have alternator/ battery problems. I have discussed the situation with the dealerto no satisfaction. …”

NHTSA complaint #765455, filed 2002-08

“This is the second Bonneville with the same problems listed owned. Seems Pontiac would investigate these problems a little more. Never buy another. After one engine replacement, will just replace the heap of a car next time. No safety defect mentioned.”
