Ever since my husband and I bought the van it when you put it in a gear and step on the gas it would rev the engine and hit hard in gear and causing the van to jerk hard we took it to a mechanic where we were told and he said it was the drive shaft and replaced it and it should not jerk no more but it seems to be worse than it was when they fixed it.

I have 3 children, one disabled. I should have known from day 1 when the manual sliding door broke two weeks after purchase. Almost killed my disabled child when it sprang open on him. Dealer, said he broke it, a child with full body muscle disorders who can't lift a brick. Now we have had unending problems with the engine, coolant levels, the car smells like burnt plastic often, times when I went to start it, nothing happened. Now I am told that the engine will seize soon. Interesting since I always changed the fluids on time and I have only owned it for 5 years. Both side doors do not work, automatic works sometimes, manual comes off the track. One of the rear passenger seats does not fold properly. The car often feels as though it has "bad gas" jerking back and forth while driving it. I am afraid, I have three kids in the car usually. I need a car and now with no money and no ability to buy a new one, I am told that the car will seize if I do not spend $4000 to replace the engine. I am getting a second opinion but from what I am reading, it seems feudal. Shame on gm!! Why wasn't this car recalled??? This is a van, a family car!!! You want to kill children???? I am writing my congressman and the better business bureau. This car should have been taken out of circulation until the problems were ironed out. If something happens to my children, I will make it my personal crusade to shut down all gm plants. The amount of money I put into this car is ridiculous when I had a 20 year old volvo that is still running. Shame on america! This is why our industries are failing and we must turn to foreign countries. So I have a car that I do not know what to do with. I seriously have no money to replace the engine nor buy a new car. I have children in 3 different schools the oldest needing therapies each day that I must drive him to. What am I to do?

During the first braking, the vehicle brake let go for a brief second. This happens on dry pavement during a normal stop. It was explained from the dealer that the rust build-up on the rotors may be causing the brake to lockup causing the anti-lock brakes to function. This is a very scary situation when pulling up to a stop with a car in front of you and the car will lurch forward with your foot pushing down on the brake pedal.

The center seatbelt in the second row of seats pulls out, then locks. You cannot release it to get more slack. The dealer was told about it but says it works like it is supposed to. It is a safety hazard because a young child could not release the belt; in the event of an accident requiring immediate exiting of the vehicle this occupant may or may not be able to release themselves from the restraint. The inertia wheel should not lock unless the belt is "jerked" forward such as in the case of an accident. It should allow for slack to be given under normal circumstances - also, if the occupant moves such that the belt tightens it becomes increasingly difficult to release the restraint.
