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.

This car has been a electrical/mechanical nightmare and I'm finding many, many, reports on the internet of owners having the same problem(s). 1) intake manifold gasket leaks causing catalytic converter and egr valve to clog. The result of this is exhaust gases can't escape, backing up and burning/blowing a hole in the intake manifold itself. All above items had to be replaced at a very substantial cost. 2) blinkers intermittently work. Mostly they don't work. This is caused by a defective (flasher) module located in the dash behind the 'flasher" button. This ia very, very common. 3) A/C heater blower fan stops working on speeds 1,2 then 3 resulting. This is due to resistors burning up on a module mounted behind the dash and in front of the blower motor. My question here is, at what point does someone hold the manufacturer responsible for these obvious factory defects. All you have to do is google any of the above complaints and see how many people are affected. Help !!!

There is a huge amount of oil in the coolant in my 2001 Chevy Impala. Knowing just a little about internal combustion engines probably an intake gasket leaking. For a car which has been very well maintained with under 80,000 miles on the odometer this was alarming. High engine temp and a sludge in my motor are the obvious consequences. Who knows what the long term affects will be. The car is now at the mechanics and already I am looking at 700 to 1,000 dollars which I do not have to repair.
