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.

Malibu 6-cyl

  • Automatic transmission
  • 40,000 miles


I own a 2001 Chevrolet Malibu with less than 41000 miles. Recently the intake manifold gasket failed, allowing coolant and engine oil to enter mix. After doing some research, I have found that this has been an on going problem with this type of car. Chevy expects it customers to fix this problem out of their own pocket and denies any responsiblities. Again, if you investigate this matter you will find that this particular type of GM car is very prone to this failure. I believe that this is a safety issue due to the fact that once manifold gasket fails the engine may stop without warning, and then fail to start.

Driving at hwy speed check coolant light came on added coolant took to local garage. The lower intake manifold needs to be replaced at a cost of approx. $900. It only has 44,000 miles and I have had all the required servicing done to this car.the garage tech said that they have had to replace this on several other Malibu's. this must be a defective part as it should not have to replaced this soon. What can be done?

While driving coolant light illuminated on the dashboard. Consumer added coolant, and noticed coolant stains on the left side of engine. Dealership performed a diagnostic test which indicated that the lower intake manifold gasket was bad.

Since I had bought my 2001 Malibu in October of 2003 I have had to add coolant intot he car about every other day. I finally got fed up with doin that and decided to have it pressure checked. Once I did that I found out there was a leak in the intake manifold. The company that did the pressure test also told me that they have repaired this exact part in several other cars within the last two months. Please tell me what can be done about this.
