Defect investigations
Power sliding door
Odi evaluated general motors' (gm) data, conducted consumer interviews, inspected and tested my 2005-2007 gm minivans with regard to the alleged defect of a power sliding door (psd) opening while the vehicle is out of park.odi identified a high warranty claim rate.however, these claims are related to various problems associated with doors not properly opening or closing and not specifically to doors opening while driving.the condition of the psd reversing direction during the closing sequence is consistent with an obstruction of the door, or with improper alignment of the door, and this is addressed in gm technical service bulletin # 07-08-64-007 and bulletins # 07-08-64-007a through d.odi's evaluation of the psd system notes numerous safeguards to preclude both unintentional and intentional power opening of the psd while the vehicle is in motion.a safety-defect trend has not been identified at this time.accordingly, this investigation is closed.[see document file for additional information regarding this resume.]
EA07019
Power sliding door opening
Odi has received reports that the power sliding doors opened without command while the vehicle was in motion on model year 2005 and 2006 general motors minivans (chevrolet uplander/venture, pontiac montana sv6/montana, buick terraza, and saturn relay).some reports indicate that the door may not have been closed and latched before driving away causing the door to reverse (open) at low vehicle speeds.however, other reports indicate that the door was initially shut then opened after driving for several minutes and/or miles at vehicle speeds between 20 and 70 MPH.odi has upgraded this preliminary evaluation to an engineering analysis (ea07-019) to further assess this issue.

The veh has a niose in the rearafter start up, sometimes it go away after driving for a while but it come back over and over again, I took it to the dealership they suggested I replace the controlled arm right and left and replace the steering sensor along with the thermostat and this will fix the problem the cost will be 1,500.00. Is this a recall problem.
While making a left turn onto another street at approximately 12 MPH, the left rear ball joint pulled completely unseated. This caused the wheel to no longer spin and pushed the top against the frame causing damage to the following: upper control arm, upper pivot bushing, and knuckle on the left rear wheel. I did have the ball joint replaced and currently am in need of replacing the bushing and knuckle. All in all, these repairs will have cost me: ball joint replacement and labor approximately 267.00, bushing and knuckle 165.00, and upper control arm 65.00, plus tool rentals. Luckily I was not driving any faster at the time of incident, but still it caused loss of function and steering based on that. There is a recall in canada for this issue but has not been issued in the u.s. I'm seriously considering a lawsuit against gm for this as it is used not only as my working vehicle for my job, but also to transport my family.
