Latches/locks/linkages: doors: latch
- What is wrong
- On certain minivans equipped with second-row bucket seats or captain's chairs and a power sliding door on the passenger side of the vehicle, a passenger using the interior handle to open the power sliding door could be injured.
- Risk
- If a passenger uses the interior handle to open the power sliding door and holds onto the handle while it is being opened by the motor, the passenger's arm may be pushed into the seat back or armrest and a wrist or lower arm injury may result.
- Remedy
- Dealers will replace the power sliding door interior handle on the passenger-side. If the vehicle is equipped with a power or manual sliding door on the driver-side, the interior handle will also be replaced for appearance reasons. Note: before the vehicle is serviced, gm advises owners to not use the interior door handle to open the door. The driver can open and close the door from switches at the driver's position or by using the remote key fob. The driver should tell passengers to use the switch located in front of the door to open or close it. The driver should use the override switch to prevent operation of the power door by children or by others who are not familiar with its use. The owner notification letter mailing will be conducted in phases with the first phase beginning on may 31, 2005. The second phase mailing began on july 18, 2005. The recall began on may 31, 2005. Phase 2 began on july 18, 2005. Phase 3 (final phase) began on august 24, 2005, to all remaining customers.

- Remedy
- Dealers will replace the driver air bag module. Owner notification began february 1, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact pontiac at 1‑800‑762‑2737.

Defect investigations
Power-sliding door
Subject vehicles are available with an optional power sliding door.the interior handle is oriented in the vertical position in the door panel and lines up at the elbow level when the occupant is seated in the 2nd-row outboard position.if the occupant holds the interior handle in the thumb up position during power-assisted opening, the arm/wrist can be push back with force against the 2nd-row bucket seat or captain's chair seat back creating a risk of injury (other seating configurations have ample seat to door clearance to avoid entrapment of the lower arm).among the 103 total reports, there were 102 alleged injuries including arm/wrist, thumb and shoulder injuries.a count of injuries reveals that 76 injuries were a fractured or a broken arm/wrist requiring an immobilizing cast for four-to-six weeks.all injuries involve the right side power sliding door.the left side power sliding door is on far fewer vehicles, but more importantly, it produces less force.gm notified the agency by letter dated december 21, 2004, that it will recall model year 1997 though early 2005 gm u-van vehicles equipped with a right side power sliding door and with 2nd-row bucket seats or captain chairs (the federal safety agency recall #04v597).as part of the recall remedy, gm will replace the door handle with a flush mounted handle that will prevent an occupant from grasping the handle with the palm between the handle and door panel (thumb up orientation) and thus eliminate the potential for arm/wrist entrapment.this investigation is closed.

Rear axle trailing arm failure
On november 18, 2002, odi opened a preliminary evaluation (pe02-086) to evaluate allegations of rear axle trailing arm failures in the subject vehicles (u-van) which included two reporting crashes.on april 9, 2003, odi upgraded pe02-086 to an engineering analysis (ea03-005) to continue its examination of the issue. The trailing arm design in these vehicles has been used in the u-van from my 1997 through the present.the gm analysis concluded that the subject trailing arms could crack or buckle if they were damaged during assembly, pre-delivery handling, or subjected to certain service related abuse conditions such as improper towing or jacking.analysis of odi and gm data has identified 19 incidents of rear axle trailing arm failures in the subject vehicles.there have been no new reports to odi or gm in the last 12 months and only one new complaint in the last 21 months. Due to the low complaint rate and the absence of a continuing trend in reported failures, a safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.accordingly, this investigation is closed. The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist. The agency will take further action if warranted by the circumstances. For additional information, see the attached closing report.

What 1999 Pontiac Trans Sport owners say
Most recent owner complaints, unedited.
With respect to my 1999 pontiac transport van, october of 2003 the engine started overheating and we discovered that the coolant was low. We added coolant and some type of seal into the coolant because we were told by several gm mechanics that it was probably the head gasket and this seal would help to get us by until we could have it fixed. I called the company where I purchased the van (2nd hand) and the van was no longer under warranty (over by 4,000 miles at the time). I did purchase the extended warranty. We priced around for the cost to have the head gasket repaired/replaced and found that we would have to spend between $800 and $1,000 to get it fixed. Our van is now sitting in a garage being torn apart and the head gasket was the problem. Prior to october 2003 we had the coils changed and the #5 plug was showing a malfunctioning problem which was showing up on the computer. When we brought it to the garage they replaced the plugs. We were told by the mechanic who is currently working on the gasket that the coolant was leaking out on the #5 gasket and this was the problem previously which was not picked up on by the past mechanic. This has been an ongoing problem for us since about june of 2003.
Problems with the sliding door, headlamp fell off, automatic locks/window and etc. *ph the consumer believed the vehicle has a coolant leak. The fuel modulator and spark plugs were replaced.
Intake manifold gaskets (upper & lower) need to be replaced because it is leaking engine coolant. Also need to replace thermostat and gasket. Cost $900.
Transmission failure caused by antifreeze in transmission. Corrosion of radiator causing antifreeze to mix with transmission fluid. Now is overheating caused by intake manifold gasket leaking allowing antifreeze to get into crankcase. Potentially fatal for engine.
Retractor mount not secured to upper panel, top threads into pillar not done, installed missing bolt in seat belt mount.
While exiting a parking lot, the rear sliding door opened, the dealer found that a bent bracket in the door mounting was the apparent cause of the door failing to latch properly. Nlm
While in driveway was adjusting front seat and vehicle started smelling like smoke. Consumer looked under seat, and one of the wires was completely bare. Consumer contacted dealer, and dealer did repairs. But, wires were still hanging from under seat.
The engine has been making a clicking sound or drumming sound for quite a while now. I have taken the van into the dealer on a number of occassions. I have since learned that my van is not the only van to make this noise, and that some vans have had the engine replaced because of it. Something about the pistons and wall chamber. The van has also quite running while I was driving w/children, and when braking, an awful loud noise comes, sounds like the car is falling apart. I refuse to take the vehicle back, and am having loads of problems dealing with this.
8 passenger van, tried to get 3 different types of car seats to work in the second row of seats, but seem unable to do so. The buckle part of the seat belt seems to come out to far from the seat allowing a large gap so the child seat can not fit tightly into any of the 3 seats in the second row. It is my understanding a carseat should not move anymore then an inch after it is buckled in. And when the carseats are in. The bottom corner where it buckles in, moves around quite vigorously. Allowing way more the an inch of slack.
