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. Also front rocker panel bad. Front passenger panel rotted out. Bad oxidizing on the manifold cover and exhaust manifold cover. Shame on gm for not covering all gas on the hazard light malfunction and multi switch issues.

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.

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.

Vehicle constantly overheats cooling fan does not come on. Fluid level needs replenished constantly. Engine pressure build up from the overheating. Still cannot resolve the problem and very costly to repair in the shop. Please do something with these cars have researched lots of the same issues on the internet. Estimated cost to repair 967.00. Which some people cannot afford. This is a manufacture issue as the intake manifold seem defective.
