I own a 2000 Pontiac Montana, in the past 2 years I have had to replace the waterpumpx2 and intake manifold gasket X2. The gasket lasted 18 months and the waterpump 3 months. I feel that putting $1400 dollars into a vehicle within 18 months for the same parts is outrageous. The serviceman however stated the warranty was 1 year. Something seems very wrong with this picture.

On Sept 26, 2006, I have my Pontiac Montana my 2000 vehicle service in a dealer for issue of engine vibration occasionally. The repairing fee is about $1000 to replace spark plug and coils. At 5:36 pm of during my driving back home in I-696, my vehicle engine suddenly stop running at about 75 mile/hour which made me almost become involved in a deadly accident. At this time, I called the dealer to inform this issue and dealer made a note. When the engine stopped running, the dic was lighting up without any information. I came back to the dealer and they were not able to find anything wrong. I was asked to usa a recording data tool, however, the next a month, the vehicle was running ok without incident. Therefore, I stopped recording data for the vehicle. In January of 2007, the same problem began to happen again. 3 times when I driving the vehicle at 60 to 75 mile/hour, the vehicle engine stop running suddenly if the brake was pushed. Then I went back to dealer again for trouble shooting on 1/4/07. They still can not find anything wrong and then schedule to a full check on 1/9/07. However on 2:30 pm of 1/8/07, the vehicle can not be running and has to tow to dealer again. In the meantime, I called GM and dealer to report this incident. I had twice in a very dangerous situation and put my family and myself life in a very harmful situation. GM give me a case number 71-476-171970. The dealer informed me that they can get vehicle started but can not resolve the issue of engine suddenly stopping with brake pressed. I need to pay $711 for the vehicle running and then go from there. The dealer and GM had a talk, then GM representative told me she will pursue to reimburse me the repairing fee. Then after 4 days GM told me again they will not to reimburse me the money now since I am scared for the engine stop issue, I can not drive vehicle over 65 mile/hour.

I found that this is a common problem on this model engine either due to the dex cool coolant or the gasket. If this sin't fixed, it could lead to being stranded or stuck in a dangerous loacation.
