I owned a 2003 Buick Rendzveous that had a intake gasket go bad due to the use of Dexcool antifreeze. It cost me 1200.00 to repair, GM is fully aware of problem dating back to 1999, but chose to do nothing about it.

Dex-Cool radiator fluid damaged the engines and created a rusty sludge in the radiator. It damaged the manifold gaskets and created heater problems. the dealer that sold me the vehicle, a 2002 GMC Jimmy, ID 1gks13w512204722. This vehicle has been serviced regularly the lazt bell was for an oxygen senser for the heater for386.43 12/03/2007. The radiator was serviced with DEX Cool when the sensor was replaced. he mechanic informed me that DEX-COOL was the best and not to worry about the pending lawsuit.

The radiator leaks and it has caused damage to the heater and manifold resulting in probably at least 100.00 in repairs. The general inconvience has cost me to lose work hours and utilize my sick time to adjust for the repairs to this car. I purchased the car 08/09/2004 from this dealer. This vehicle only has 33139 miles. I wopul like to be compensated for my loss.

The Dex-Cool coolant in my 2002 Buick Regal has caused the intake manifold to leak, and will cost several thousand dollars to fix. I thought this coolant was good for 100,000 miles but I've flushed and refilled at the 70,000 mile mark because it was 5 years old. What can be done about this? GM refuses to repair the car.

I just recently bought a 2007 pontiac g6-gt it made a loud noise and had the smell of burning rubber, I thought it was the fuil pump-which it was not and the dealer said it was the turbo. A friend of mine informed me that that year did not have turbo, I took it to a GM dealer come to find out it was the converter or the muffler. turned out it was the muffler and a gasget, cost was over 1,000. One month later I still smell the burning which was not fixed and a low red/pink fluid. My neighbor came to see what I was talking about and told me to get the car in ASAP and not to use this coolant due to problems. I have only had the car 3 months and problems, don't know what to do. expected

I have been having cooling system problems with my 2004 Chevy Silverado with only 70,000 miles on it. I believe I have been losing coolant through the intake manifold gasket. I have had to keep a close eye on coolant levels and have been putting in at least a gallon of GM recommended Dex-Cool every month. The initial low coolant problem has caused damage to the cylinder heads, and possibly to the motor. The dealer showed me extensive sludge in the oil while performing an oil change. I have an appointment to begin repair next week. Am I covered under the class action lawsuit? It is going in for repair next week. The (non-GM) mechanic told me Castech heads may be replaced my manufacturer, but I think GM should pay for the work.

We have an 04 4x4 crew cab Chevy truck. It has 76,000 miles on it. It started to lose coolant and we had it diagnosed. It was determined that it may have a porosity problem with the cylinder heads. These heads were manufactured by Castech. We contacted GM about this. We know they knew about this problem but refuse to do anything about it. They say the truck is out of warranty so it seems its not their problem now. We would like to know if there is anything that can be done about this.

I purchased a 2003 cadillac cts in 2002. I followed all relative instructions in regards to scheduled maintenance on my car. Including the do's and don'ts of servicing my vehicle, but I can say in most cases I allowed cadillac to perform at least 95% of the maintenance such as oil changes, tune ups, inspections, etc. In 2008 I noticed my car would give off a funny smell when the a/c was turned on. I assumed it was low antifreeze so I purchased some Dexcool antifreeze as per the manual and expected better results but to no avail nothing improved. As the summer passed and winter arrived I noticed the problem got worst and I could not afford to neglect the problem as it was freezing in ny.

Therefore I took my car to cadillac and they told me my it would cost x amount of dollars to repair the problem which I could not afford. I sought a second opinion and a mechanic advised me cadillac has been using dexcool antifreeze and the antifreeze is eating away my engine and eventually my car would be completely damaged. I would like to have cadillac pay for the damages on my car due to their recommendation to only use dexcool antifreeze. The antifreeze has damaged my car and it is constantly overheating. If I run the car for 2 minutes it will overheat in another 10. Its ridiculous. I would like to be a part of any class action suit.

Dexcool was used in my car by my mechanic, because that is what GMC specified to use. This is two times now that I had to get my heat fixed, which both times cost me almost 300 dollars. Dexcool antifreeze clogged up my heat pumps, so heat was not able to flow through. My mechanic actually showed me what is looked like and it looked like a whole clump of mud.
