I went to a site and found others complaining of similar problems with their Buick Rendezvous. My mechanic found a used trans with only 42 miles on it. Since modulators control shift firmness, a bad modulator can result in slipping gears. The consumer knew of technical service bulletins issued for this problem. My mechanic said it is a common problem. This car is a total piece of garbage. I'm not saying that I am going to leave the old fluid in there, it is going to be changed it is just that I haven't done it yet.
I drive 100-125 miles a day, 3-4 days a week just to get back and forth to work, and it is straight highway most of the way, although it may be easier on my tranny than city driving, my transmission still runs as good as the day I got the car, also a rdvz is not meant for speed or even really for being a Sport Utility Vehicle. I wouldn't recommend anyone buy one. The service allows to compare and analyze statistics for reported problems, complaints, recalls for various manufacturers. Transmission problems have been identified for every model produced by Buick, though some years have fared better than others. I have been researching about the transmission for this vehicle and it seems after 60k miles the transmissions starts to go bad.
It's has almost all highway miles. Now I am stranded, car less, and my husband is deployed and can't help take care of the issues. I was merely giving advice like everyone else on these forums, so that somebody out there doesn't go and switch transmissions right when something seems to go wrong. You get to realize how heavy the vehicle is - it needed 3 people to push, unlike my old tericel. Later, car rolled backward and hit another car in parking lot luckily no one was injured. I called and after 2.
Don't read this wrong, I'm not saying it's not true or possible, just kinda odd. When the solenoid valve failed, metal flakes got in the fluid and ruined the rest of the trans. When they run right, they are a smooth ride. I hope the new one gives you better service than your first one, I hate for it to make a liar outta me. The problems reported vary from transmissions shifting erratically and loss of transmission fluid to transmission failure.
At 70K the passenger side wheel bearings went out. I think they need to be looked into more carefully. Can not afford to trade and should not have too. So maybe try that out before you go and overhaul your tranny. Now at 74K, the solenoid valve assembly for the transmission has gone bad. My Intrepid 1995 didn't have anything out of the ordinary go wrong until 135,000 miles, and that was the power window motors. We were informed by him that this vehicle would be accepted even under the miles progam and that our vehicle would meet and exceed those.
The car immediately started to roll backwards, as it was parked on a gradual slope. I've seen numerous posts of this problem at automotive forums. These sensors should always be checked first in the event of transmission problems with these models. Have had many close calls of being hit when this happens and have had the vehicle in 5 times to the dealer to diagnose the problem to no avail. I was trapped behind the left side passenger door until the car made a slight turn and I was able to get out from behind the door. Can't hardly tell when it shifts now.
There are also some other problems reported in Buicks which may be mistaken for transmission issues, such as potential looseness in the throttle pressure cable connecting the carburetor to the transmission in several models. I guess bottom line is that no one wants to make good on a vehicle that we have only had for 1 year. They say they can not duplicate it when they drive it. The dealer replaced the transmission. Dealer indicates that the keys cannot be removed when car is in drive. Anyhow, Buicks are nice vehicles, but I've come to the conclusion that they are all style and very little if any substance. The blower for the heat or air conditioner only works on three or above, the air conditioning no longer works, both rear coil springs must be replaced, an outer tierod is bad, two rear bushings need to be replaced, the front right control arm is broken, the drivers side window goes down but not up, it is leaking antifreeze and the tires keep going bad because they are wearing incorrectly.
In March 2009, while driving 10 mph, the contact stated that the vehicle suddenly stalled without warning and he was unable to shift into drive. After only 80,000 miles the transmission was replaced. Each rdvz is different and have different problems I was just putting my two cents in. The consumer stated the vehicle did not shift properly and accelerate properly from a stop. But that's not good enough.
The mechanic said it usually happens because the transmision fluid is too old and not changed. We explained to the gentlemen named tim that we would be making a few trips back and forth from kansas to texas. I have had 2 other people experience this problem. I am a full time employee and I am also a full time student. The approximate failure mileage was 73,000. The vehicle we purchased was a 2003 Buick Rendezvous and this was done through Toyota motor credit corporation. Every time I turn around it needs another repair.
We bought it in Nov 2004 with 16,000 miles. The solenoid is just a bad part that needs to be recalled. When diagnosing a problem with a car you don't do the most expensive thing first unless you want to , you should start with the cheapest part that you would believe to work. Anyhow mine still has problems shifting but surprisingly still makes it. . I know what you mean about the problems. So anyway we have it a year to date and I am making a trip to kansas when it goes haywire.
