Bought the car aprox. 3 years ago,a 2003 Buick Rendezvous with 30,000 miles on it,it now has aprox. 60,000 miles on it. Within the last year [ 2008 ] it has started loosing coolant,not externally,having to refill overflow tank every 1,500 to 2,000 miles,we have the vehicle serviced every 3,000 miles,using pure synthetic,with the amount of upper engine gasket failures ,apparently caused by antifreeze deterating head and intake manifold gaskets,ending in catastrophic gasket failure,and most of the coolant in oil,and the only repair is replacing defective gasket,where as the proper repair would be for the whole engine to be replaced,has there been a recall or class action taken here in the u. S. I know canada has, I am concerned because my engine now has a bottom end rattle,ie the crankshaft and or connecting rod bearings worn, I have done auto mechanic work for 30 years and I know this is a sign of premature ware,then engine failure,and I feel g. M. Should be 100% responsible for engine replacement,please advise.
Engine ran hot. Service repaired the intake manifold gasket. All coolent was lost, but no leak was found under car. Gasket was replaced.
Intake manifold gaskets corroded by gm coolant after a couple years. Specific to combination of factory coolant and factory gasket. Mechanic replaced gasket with one that doesn't corrode when in contact with the factory coolant. This required 6. 5 hours of labor plus parts totaling $600.
Intake-manifold started leaking at 69,000 and will cost me $800. 00. Was told this is a common problem with 2002-2003 Buick rendevouz's.
The first indication of the problem was that the when the heater was turned on, it would not get warm or hot. I took the car to the dealership, they stated that it was the intake manifold gasket, which is a $900 repair. What they did not tell me was that, when this gasket leaks coolant, it will mix with the engine oil and cause the engine to blow or seize. In researching on-line, I have discovered that this is a well-known problem that both general motors and Buick are well aware of. In fact, gm sent out an internal service bulletin in July 2001 stating that the intake manifold gasket was defective and that when brought in to the service dept. , it should be fixed. Only they will not recall the defective part or pay for or reimburse consumers for the repair. This is outrageous! there are thousands upon thousands of people out there stating this same exact problem, yet gm refuses to recall it! there is a class-action lawsuit in canada for this exact problem and a petition for gm to recall this defective part in the u. S. Gm should be forced to recall this defective part that they have been deceiving consumers about all along. There is no excuse for continuing to sell vehicles with this problem and not so much as do a recall. I want to gm to pay for the repair as well as recall the part. I have already spent over $700 in repairs to the car, including wheel bearing sensors, brakes, and a gas-line leak. These are also well-known issues with the Buick Rendezvous.
Failure of manifold intake gaskets, and manifold cracked, both at 43,000 miles.
2003 Buick Rendezvous cxl 75000 miles cooling temperature varied widely indicating a possible problem. Took auto to authorized repair shop who replaced intake manifold gasket at 75000 miles.
The contact owns a 2003 Buick Rendezvous. The contact stated that the vehicle began to leak antifreeze, which caused it not to produce a lot of heat. The vehicle had to have antifreeze added every month, but the contact never actually saw it leaking. The vehicle was taken to a local repair shop and they stated that antifreeze and oil were leaking into the intake manifold. The repair would cost $700. The vehicle has not been repaired. The manufacturer stated that there was no current recall; therefore, they were not liable for any expenses. The failure mileage was 30,000 and current mileage was 105,000.
