2005 Pontiac Montana Sv6 - 1GMDX33L75D- Park Rapids, MN: January 2nd, 2011
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.

My 2006 pontiac montana sv6 was parked on a small incline, and while low on fuel (it had about 3 gallons) the van acted as if it was out of gas and would not start. Gas had to be added and the van pushed to a flat surface.

2005 Pontiac Montana Sv6 - 1GMDV33L35D- Houston, TX: January 9th, 2009
I have a problem daily with the passenger side power sliding door, when i close the door it comes back open. I have to open and close the door several times for the alarm chime to stop and the door completely close. I have taken the vehicle to dealer who claims to have fixed the problem when the van was under warranty, but that's not true because the problem still continues! This is a safety issue especially since i have small children. I have taken my vehicle to 4 different dealerships who have been unable to fix the problem. I believe it should be a recall on the power sliding door for the 2005 pontiac montana.

2006 Pontiac Montana Sv6 - 1GMDV33L56D- Mulgee, OK: July 9th, 2008
The contact owns a 2006 pontiac montana sv6. When the vehicle is stopped and idling, the battery voltage begins to decrease. The vehicle has been diagnosed by the dealer several times; however, the failure continues. Also, when the contact places the vehicle into drive, the rpm's increase, but the vehicle does not accelerate. The vehicle was diagnosed for the failure, but it still persists when the contact attempts to drive. In addition, the driver side door on the vehicle does not properly shut and leaves a one inch gap between the door and the body of the vehicle. The engine will also attempt to turn for 30 seconds, but will not turn over completely. All of the failures occur intermittently and were serviced by the dealer while the vehicle was still under warranty. The current mileage was 38,000 and failure mileage was 20,000.

2005 Pontiac Montana Sv6 - 1GMDX33L95D- Plainfield, NH: March 19th, 2008
This vehicle is equipped with an all wheel drive system, which is necessary in our environment to climb icy or muddy hills to get to our house, or friends' houses, all on dirt roads. It's also very beneficial for driving on icy and slushy roads which are frequent around here. We have three vehicles, all awd or 4wd. On the 2005 pontiac montana sv6, however, there appears to be a sensor on each wheel which is integral to the awd system. This sensor is apparently easily obscured by ice, slush, or mud splashing up into the wheel wells, and when this happens the vehicle disables its all-wheel drive system, leaving the driver with a fwd vehicle, which can often be insufficient to handle conditions entered with an awd vehicle. So far we've been stranded at the bottom of icy hills and narrowly averted two crash incidents due to the awd system disabling when driving through slush puddles or mud. The dealer has been able to clear the sensor and reset the system twice - on the third incident we were told the entire right front hub assembly would have to be replaced, so apparently slush can permanently damage the awd system as well. This problem was reported to pontiac via their website and they haven't bothered to respond.

2005 Pontiac Montana Sv6 - 1GMDV03L95D- Pearl City, HI: January 10th, 2008
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.

2005 Pontiac Montana Sv6 - 1GMDV33L95D- Broomfield, CO: December 6th, 2007
The "air shocks" that propel and hold up the liftgate of our 2005 pontiac montana sv6 failed. There was no evidence of possible failure prior to the actual failure. The lift gate is extremely heavy and it poses a safety hazard. It does not hold itself up once opened and should it fall, the heavy liftgate door would slam shut injuring anything or anyone in its way. We have used it on the rare occasion that we had to, and it is extremely difficult and heavy to hold up and open, and we must gingerly close it to prevent the back window from breaking should it close too hard. We were fortunate that our failure occurred when we were trying to open it and it wouldn't open as it should. We fear that a severe injury or death could result should the failure of the liftgate occur while it is already open.

2006 Pontiac Montana Sv6 - 1GMDV33LX6D- Hudson, FL: October 13th, 2007
2006 pontiac montana van, 9,000 miles, rear stabilizer snapped completely in half while under normal driving conditions. No encountered with road debris, pot holes or other outside influences caused this problem. A loud noised was heard by the driver and she felt the rear end wobble. She pulled the van to a stop. The rear wheel and "axle" became "free floating and detached from the frame" causing the tire to roll backwards into the wheel well and the stabilizer to fall to the ground. Fortunately, this happened in parking lot while moving less than 5 mph, and not at a highway speed. The dealer who is conducting the warranty work stated that he had never seen this problem, but would report it to gm and also noted that no other area under the car had any damage, indicating that it appeared to be strictly a failed structure. The "stabilizer had apparently just snapped", he stated. The van had never been involved in any accidents and was purchase new from a certified gm dealer. The whole rear end, axle, brake lines, stabilizer and other related parts have to be replaced.

2005 Pontiac Montana Sv6 - 1G2JB524217- Sauk Rapids, MN: August 30th, 2006
Trim strips on both sides of van were rusting even though they were plastic. Was told that this was a known problem, there should be service bulletin on it, and that the paint surface was not cleaned properly before painting it, therefore iron/rust was bleeding through. This happened only on the trim strips on the front doors, no where else on van. Strips were replaced since still under warranty and no problems yet after 2 months. *jb

Since vehicle inception, all tires need air every 2-3 weeks. At 5000 miles hit a pothole and bent rh front rim outside bead (air pressure good). Took it to the dealer and they rotated the tires in a x pattern rh front to lh rear, lh front to rh rear, etc. Lh rear became rh front, which at 7200 miles while driving down the freeway the rh front rim bead breaks and the bead punctures tire causing momentary loss of control. There was no one in the area at the time and vehicle was pulled to the side of the road. *nm
