Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Around 58K miles the low coolant light came on and I was informed that there is a slight leak around the intake manifold gasket. This was a common problem due to the dex-cool antifreeze that is used. I have contacted the dealer and they won't do anything for me, and the cost would be around $700 to repair. I've been nursing this issue for several months as the leak was slight, however now it is greater and must be dealt with. I have gotten nowhere with the dealers and will have to repair it and bear the cost.

2002 Chevrolet Impala, coolant light has been on for 2 years. Took it to a dealership when it first came on, only to be informed that it was a "corrosion problem" which was not covered by my bumper to bumper warantee. Now I discovered that GM's choice of dex-cool antifreeze is very well known to cause corrosion problems, and there are a myriad of consumer complaints about dex-cool destroying head and intake gaskets as well! I expect GM to make good on a problem that they themselves caused, instead of their to-date snively policy of passing the buck back to the consumer. (in short, if this issue is not resolved to my satisfaction in a timely manner, I will never buy a GM product ever again!)

Engine coolant has turned brown and clogged up the cooling system. I have been told this is a problem with the type of coolant being used in new vehicles. I have been refered to have my engine flushed and that GM will not stand up for the repairs.

While checking cooling system noticed a build up of brown stuff on radiator cap, and brown water at radiator top. Cooling liquid breaks down and clogs up radiator/ heater core and engine. Dealer has been contacted.
