Grand Am ES V6

Leaking coolant (no signs though). Had to refill it weekly. A mechanic told me it was a intake manifold gasket. Sounds like everybody else had that problem. I wonder where could you report that.

Grand Am SE1 3.4L V6

  • Automatic transmission
  • 77,800 miles

Talked to the GM Dealer again. Said that they aren't going to help me at all.

Cost is over 1 grand to fix. Car is sitting at dealership right now. Still driving the G6.

I'm starting to think of going brand new now. I don't need this headache. But I believe GM should pay for at all of this.

I wish everyone who has this problem luck.

I am ready to explode. I have a 2003 Pontiac Grand Am, which I purchased with 30,400 km's on it in 2004. Then in 2006, it started leaking coolant. It overheated twice. Took it to numerous GM dealers, they said nothing's wrong. We can't find anything wrong. Had the thermostat replaced in March 2006. (This was at 70,000 km's.) Car was fine, but couldn't use air conditioning in the summer, because it would overheat. Also if the windows were down car would overheat. I knew there was something wrong, took it back and they told me the same thing as before. There's nothing wrong. Took it back in January 07, as coolant leaked completely out of reservoir. Phoned GM dealer, and they said bring it in. Took it in, what did they tell me. "We pressure tested it, and can't find no leaks." I took the car back, and over the weekend it leaked everything out AGAIN! I didn't even drive it on Monday. It sat there. I phoned the dealer told them I had to keep putting coolant in, there like bring it in we'll get you a rental. Got car back a day later, told the same thing there's nothing wrong. It continued to get significantly worse, so I took it in again. I mentioned to the service tech that I thought it was head gasket and intake manifold gasket. He disagreed with me. So far, to make a long story short, my car has been in the dealership 7 times. I'm driving a 2007 Pontiac G6 (from Enterprise) and found out the other day it's my head gasket and intake manifold gasket that are gone on my Grand Am. The service manager said it's "seeping" and it's nothing to worry about. Worry about my ass. Stay far away from the Pontiac Grand Am.

i noticed something leaking on the snow i took the car into a mechanic in Bradford, ON, he told me that it would cost me around 1 grand. just after christmas too much. i looked this up on recalls and found that this problem is happening more and more why is this not being a recall. i have extended warranty and bye the bye it better be covered or i will never buy gm cars again.

This is a nightmare, only symptom I noticed was some whitish smoke when accelerating, dealer tells me oil leaking into coolant system and vice versa, has been for some time. Now the entire engine is a complete mess, now coolant system needs complete flush, all hoses need to be replaced, etc. I have an extended warranty but they will only cover the $750 to replace the intake manifold, but not all the damage that it caused, which is more of the expense!! I do not have nor should I have to pay $1400+ for repairs that GM should cover, knowing that they produce a faulty part which leads to damages like these!! What can I do?? (So far have only authorized warranty covered repair and radiator system flush.) I am a young, low-income (for NJ, its crazy expensive here) unmarried woman and 8 months pregnant, this is really the last thing I need to be dealing with right now!!!

The Low Coolant light began coming on. I took it in to get the oil changed and told them to look at it they said they put some coolant in it and the car was fine for a week. It then came back on I called the original service provider back they had it for 1/2 a day and said it was a little low on coolant and if it happened again to take it to the dealer. Well, Light comes back on another week later! I figured it must be some sort of electrical short so I did nothing until my heater wasn't working very well and my temperature gauge started moving where it shouldn't. This time I called the dealer and $960 later and a tin can for a rental - it was the intake manifold gasket. He couldn't explain why this happened, only that he's worked on over 20 vehicles of this year and model with the same problem -

Pay attention to your dash lights and don't hesitate to get a second opinion :)

Grand Am SE

Defective intake manifold gasket allows antifreeze into the engine, contaminating the oil. Dealer admitted it's a common problem with the 3.4 L engine, but since I bought the car used, GM won't cover it. This problem should definitely be a recall.
