“My ignition cylinder switch is making my car to stall and shut off while I am driving and I had it replace on 4/8/15 and was driving and it not fix, my car has cut off on me while driver 3 time since I got it from the dealership I am not driving it and what the dealership to send a tow to pick the car up. I am not safe in the car and spent $377.00 for labor and the part for it not to function correctly. I had my key replaced on a recall and when I got that service my ignition locked and the key would not turn the car on.”
NHTSA complaint #10705146, filed 2015-04, 242,796 miles“I had 2 kids in the car,the accelerator pedal stuck,car kept speeding up.. I was using both feet on brake & er brake as well!! I was swerving in & out of traffic,running red lights & praying for our lives,we got up to 85 miles per hour in a 35mph zone!! The car was revving out of control & black smoke was coming out from under the hood! I managed to slam it into park & we all jumped out & ran,very frightening & almost ended in a collision. The intake manifold gasket cracked at 1yr old and 10,000 miles,the tires needed resealing at 5000 miles. Ridiculous!!”
NHTSA complaint #10596041, filed 2014-06, 20,000 miles“Coolant leaked into engine caused problems, wouldn't start half the time, couldn't fill up without gas pump cutting off constantly (took 20 minutes to fill up). Took car to dealer and other shops spent tons of money problem not solved. Got so feed up with this car I pulled the tags and bought a honda. It is really unfair how the manufacturer of this car was allowed to get away with putting out such an inferior product. There should have been a major recall on any number of these problems. I was never notified of any recalls or the class action law suit.”
NHTSA complaint #10500953, filed 2013-03, 50,000 miles“Hi, my grandam overheated while I was driving. I noticed that the coolant compartment was empty. I did not receive a low coolant warning from the car system. I had topped off my coolant compartment about two months ago. When I look at the engine block, I can see that there is a trail of coolant coming out the engine gasket. I did some googling and noticed that this is a common problem with the grandams and that there was a class action lawsuit filed against GM a couple years ago. I do not feel safe driving this vehicle as I worry if the engine will catch fire.”
NHTSA complaint #10490674, filed 2013-01, 99,500 miles“Bought the vehicle used. 2003 Pontiac Grand Am 3.4l v6. Constant ticking from hazard light switch. Grounding problems. Looked for recalls at GM dealership. No recalls on the problem. No choice but to remove hazard light fuse until repair. Should have been covered by GM. Gonna cost us $500! The transmission cooling lines rotted away causing coolant spraying everywhere causing white smoke and overheating of the engine. Spraying the serpentine belt and water pump. With visual inspection and touching confirmed spot. 3/4 of reservoir is leaked out causing rust on sub frame. …”
