Delay with windshield wipers, take too long to pop up and than wipe, design should have never been allowed, the couple of seconds it takes for the wipers to move from off position to when you turn them on is long enough to cause an accident on a day after it rains where you are passed by a vehicle driving through a puddle, cannot see, and could possibly injure somebody. Constantly losing power steering fluid. Transmission was replaced once due to slippage got it back and started to do so again the first 200 miles.

My 2000 pontiac montana (ext) has been accelerating on its own. I have tried to determine the cause and effect, but nothing stays constant. It may happen when the car is cold or hot, early morning or late afternoon, etc. I have taken it into a dealership and they cannot reproduce the issue. In addition, they have told me the computer did not register any codes. When the issue happens the idle. I'll put the car into park and watch the RPM move to 3500 and stay there until I turn the car off. Once I turn the car off and turn it back on then the issue stops. I have others verify the issue has happened with them or they saw the issue occur (so I'm not crazy). A mechanic at firestone (was able to reproduce the issue) and he thought the issue was related to the transmission. I'm not sure how he came to that conclusion, but they wanted to charge me $3,000 for a new transmission. At this point I think I will get a new car. Very disappointing.

At roughly 2k miles, the transmission was replaced. Then again at 28k miles, another replacement. Both were covered under warranty, but I tried to get the local dealer and gm to buy it back since it was untrustworthy for my family. The most my threats could do was get an extended 60k/$0 deductable warranty out of gm. Then at 56.5k miles, the intake manifold gasket problem got me. This also resulted in a water pump replacement.

Transmission went out at around 44000 miles. Dealer said the "lip seal" failed inside transmission, after taking it in several times for diagnosis. Would not assist with repair cost. Ended up having it repaired at aamco. A/c is currently out on the low setting (#1). Not yet repaired. Just repaired the cooling system. Dealer said it was an internal leak. Van kept getting low on coolant, had to keep filling it up, however never saw a leak. Dealer said problem with the manifold, and coolant was leaking thru and being evaportated, therefore no telltale leak. Cost $600 to repair (at 53,000) miles. I hate this van. This is the worst one I've had. Unfortunately, I did not buy an extended warranty.

There are modules that we keep having trouble with. They lock & unlock doors while driving, lock in ignition key receiver, turn on air bag warning light and disengage them, show "service engine" light, etc..I am told they control the headlights also. They are a vital part to the car\\'s saftey because they control so many elements of the car. The tranmission has had numerous problem. Wheels spin first and then engine locks in a few seconds later. They tried to repair it twice, then we drove just a few blocks from the dealership and had to bring car back (service records do not show this as an additional service) and had too bring it back again a few days later. Now we are told that they are putting in a new transmission and refuse to consider the car a lemon because a new transmission is being put in. We have lost confidence in the car and consider it unreliable and unsafe. A new transmission only addresses one of the problems. We want out of the vehicle. It is currently in repair now, and we have had a rental car for almost two weeks. Altogether, the car has been in service for about 43 days since we have owned it..just one year!!

We ought the van as a program with 20,000 miles on it,within the first month the power windows would not work all the time meaning sometimes they work and sometimes they dont. Same thing for the interior lights. In the summer of 2003 the air condition developed a sloe leak that progressed within weeks,we now have no air at all and the part aloe is going to cost $400.00. In october of 2003 on our way to a high school football game the transmission went out. There was no warning at all,it had not been leaking or acting up in any way it made a thud sound going down the hiway and that was it..no more transmission $4,000.00 to repair.
