| The events leading up to the failure, > the gmc manufacture failure to provider adequate coolant to the vehicle. the manufacture is already aware of the issues and fails to admit or correct the problem from occurring to unaware motorist. the issue is the dexcool coolant that destroying the car performance, radiator, water pumps and main fold gaskets. once this damage has started, there is no stopping it. the car is a complete lemon and it is too late or expensive to fix the damage. there has been a class action law suit on various gm models due to this dex cool issue. unless you know about the issues and research them, this can be happening to you as a gm car owner/lesser and you would not know it. the gmc dealers down play the problems you explain to them and blame the driver or just weather conditions and state this is normal and it just happens sometimes. this should be against the law and review further because nobody should have to go through this horror. the main problem is that you don't know that your creating damage to your car because you are just driving and then one day you get a message on the dash board that the car is over heating. you do not know why, hoe or even what would cause this. by this time its too late. the radiator, water hoses and main fold gaskets have been all damaged by this acid eating dexcool component and then its financially the drivers fault to pay out of pocket expenses, ranging from ($400-$4000+). i am a single mother who purchase a new vehicle so i would not have the problems of being broke down on the road or having a used car with some one else's problems. i am no stuck with a damage 2006 grand prix, car note for the grand prix $400, insurance for the damage grand prix $300 and repair cost so far est. $3200.i can not even use or drive the car until i find a way to pay to fix something i did not know was happening. this can not and should not be allowed. *tr | |||
