Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I had to replace the catalytic converter twice in the first year of purchase. I had to replace battery and alternator at 37500 miles (warranty expired at 37000). The motor in driver side door went bad for no reason. Had to replace rear seal and pins 4 times or more. I believed for a long time that it was just me but after reading through the other complaints, I realize it's the car! I have also had several of the same brake problems mentioned by others on this site. Purchased new, drove it off the Pontiac lot.”
NHTSA complaint #10010587, filed 2003-03, 27,000 miles“My service engine soon light keeps coming on (steady and flashing). All in less than 2 months I have had to replace the battery, path lock sensor and ignition cylinder, remote alarms and keys, spark plug wires, clean fuel injectors, replace serpentine belt and upgraded my gas octane in a v6. And now the stupid service engine soon light is on again and the engine is hesitating and the bearings on pulleys are making a noise (after replacing the serpentine belt). I have receipts for all of it so far. I am going tonight to read the code for what is wrong now!!!!! …”
NHTSA complaint #10093781, filed 2004-10, 64,172 miles“The air inlets on the breather for engine air intake are positioned at the front center of the engine compartment in front of the radiator. The angle of the radiator in relation to the road surface provides a chute for water to travel directly to the air inlets and subsequently to the intake and internal engine areas. There is also a resevoir just behind the air filter to catch any fluids prior to engine intake. Why? Water is not compressible, so disaster is waiting to happen when it is introduced into a cylinder. …”
