Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The car will momentarily hesitate when attempting to accelerate from a stopped position. It is periodic and not consistent, therefore, hard to duplicate according to the dealer. I asked GM to e-mail some of their nationwide Pontiac dealerships and ask for their input on this type of problem but they refused. This can be a very dangerous situation when entering moving traffic. So much for customer service. I will remember that when I purchase my next vehicle.”
