2005 Pontiac Montana: ABS light or ABS activating

Filed Jan 2, 2011 · Driver assistance, Electrical · 64,000 miles · MN

Since purchasing nearly 2 yrs ago from a local dealership, it has had numerous minor issues and some dangerous problems as well. My main concern is that the drivers side automatic sliding door doesn't function properly. We had the van looked at by a mechanic from the dealership and he was unable to remedy the problems with the door. The slider door opens randomly, won't shut, or just keeps opening and shutting for no particular reason. We've tried turning the switch off on the console, which for the most part keeps the door shut~ but then that door is unusable. Now for the most serious of my concerns with the console switch off, the door has on occasion opened on its own when the van is going down the road. Also, at least 3 times in the last 6 months, the door has opened on its own in the night and stayed open~ causing my battery to be dead in the morning. Another problem we have has is the ABS and the traction control lights come on randomly, we had the van serviced and still it doesn't seem like those systems are working properly.

Numerous attempts to fix the same and continuously different problems with our 2005 montana. Flickering interior lights, ABS system failure (4x), retorque harmonic balancer, replace radio that randomly changed stations, replace molding on all doors from rust (2x), right wheel bearing and hub assembly replacement (2x), replace turn signal lamps (2x), replace fuel level sensor, replace strap on rear door that fell off. We have had issues with it not turning over as well, going on for over a year, and each time it is taken into the shop they are 'unable to duplicate the problem' and send me home where of course it fails to turn over but won't do it when they have it in their possession. The incident date below is the date of the first time it was in for service.

This is a safety issue involving ABS system for my 2005 pontiac sv6 montana. On or about august 11, 2006 my ABS light came on while under normal operation of the van. This has been an intermittent problem over the past 6 weeks. I took it to a local independent shop to have it diagnosed and the local shop informed me that the codes were to new that I would have to take it to a dealership. After taking it to the dealership they diagnosed it as having an electrical problem. There were no faulty modules but that this was a wiring problem. I am the only owner of an 05 pontiac montana that I know. Recently I have had various other problems with the power sliding door intermittently opening whenever you engage the transmission into reverse (right side only). My 6 year old sits in the right rear seat. Hope this doesn't happen while driving down the highway. Does this vehicle have faulty wiring or do I just have bad luck.

The attached date is the latest of the failures. I already had a complaint submitted regarding a crash due to ABS failure on december 31, 2005. Since the damage was fixed from the accident and the ABS was supposedly fixed, we have had many more ABS failures. It has been to the dealer 3 times (this time being the 3rd) after the initial problem and each time they supposedly fix it (between the wiring harness, the ebcm, and the wheel speed sensor I don't know what is causing it now). They keep telling us it is a non-critical system, but it caused an accident. With the other failures after the accident, the ABS would kick in for no reason, I react with more pressure (since I'm not expecting the ABS to come in to play during a normal braking situation), then fail in the middle of a normal stop causing a near wheel lock-up. I believe this is a big safety problem and warrants a good look.

My daughter had un-buckled her seat belt because it had locked up, so I went to make a quick stop so I could buckle her back up. I stepped on the brakes moderately hard and the anti-locks activated for about 1 second, then suddenly the wheels completely locked up and the van went into an uncontrollable skid. I hit an 8" curb head on, jumped over it and landed on the front lawn of a motel and skidded to a stop. The front tires popped, the wheels were pushed all the way back to the back of the wheel wells, the frame is bent (body lines don't line up) and I'm sure there is much more wrong with it. The ABS light and traction control light started coming on about a week earlier every time the traction control kicked in. The information center would also say "service tracking system" and "service ABS system." I did as the manual says; turned the key off then turned it back on and the lights would go out. So I assumed everything would be ok in a bind. The dealership is trying to say it's my fault and that they will be filing with my insurance company. The police report notes the ABS light was on after the accident. I have pictures of the skid marks and the damage, and I am note sure the edr that this vehicle is equipped with would reflect the same thing or not.
