The contact owns a 2001 Buick Century. The vehicle's intake manifold gasket failed at less than 100,000 miles on a brand new engine. The contact smelled anti-freeze and brought the vehicle to a mechanic who conducted pressure testing. The failure was diagnosed as the manifold gasket. It is a replacement engine and it is demonstrating the same failure as the original engine that was replaced at 35,000 miles by arbitration order. Buick has refused to pay for any failed components concerning this motor, including replacing the catalytic converter. The converter was plugged from the original motor failure along with the subsequent failure from the intake manifold gasket on the new motor. The power window regulator failed in January of 2007 for the second time. The current mileage is 145,000 and failure mileage was 100,000.
Intake manifold gasket leak.
Car heater would not warm up. Temperature would then fluxuate between hot and cold. Took the car to the dealership, the dealership diagnosed the problem as intake manifold gasket failure. Coolant mixed in with oil in the engine. Dealership service department required to keep car overnight to fix the problem. Needed a rental car and no loaner was available. Gm agreed to split the cost of the intake manifold gasket repair 50/50, but would not cover the cost of a rental car. Effect of this gasket failure at this time is unknown and effect to engine and components. Car has 68,500 miles. Original owner off car has kept up with all scheduleed maintenance.
Manifold gasket needs to be replaced due to a small leak which is causing considerable amount of problems. All mechanics that I have taken this car to say there is a problem with this particular engine where gm changed to plastic gasket. All seem to have same diagnoses except gm and gm dealership.
The 2001 Buick Century was not shifting well and ran out of transmission fluid. When the reservoir for transmission fluid was refilled the fluid ran out quickly and I took the car into the local dealer to be repaired. They told me all the fluids were mixing and that if it was not fixed the antifreze and water would have leaked into the oil and blew the motor because the lower intake maniforld gasket was bad. The bill from the dealer accounts for leaking transmission fluid lines and the li manifold gasket. These were expensive repairs and the reason I decided to report them was that my son and daughter-inlaw both have new gm vehicles and have replaced the intake manifold gaskets on one of them 2 times and the other 1 time for a total of 4 intake manifold gaskets for out family. They have a 2001 and a 2002 alero. Now my daughter is also describing what may be the same problem.
Our well maintained 2001 Buick Century with a 3. 1 l v6 has developed an intake maniold leak at under 75,000 miles. The car has been wonderful since purchased new - until now. Internet research has revealed that gm used a "plastic" intake manifold and it has been problematic. It was also revealed through research into gasket manufacturers that the 100,000 coolant is more corrosive that gm anticipated. Now, where does the responsibility lie for the manufacturer (Buick div) to take ownership as a responsible corporate citizen and provide some replacement cost relief to the customer? I currently own 3 general motors vehicles, however only 1 with the problematic intake manifold design. I look forward to hearing from someone soon. As a marketing manager for a major company, I can assure gm that customer loyalty is what drives my business success. In order for me to select gm for my next vehicle, I would like them to tell me what they will do to remedy this design flaw problem of intake manifold gasket failure. Thanks, art pandaru.
