“Shifting out of park while engine not running without the brake being on/stepped on, which resulted in the van rolling in reverse, thankfully it was in the driveway when this happen, was able to put it back into park (thank god).”
NHTSA complaint #10811171, filed 2015-12, 135,769 miles“Lower manifold and water pump are both leaking on vehicle. The water pump and the manifold gaskets needed to be replaced. The first major failure occurred the day after the consumer took delivery of the vehicle. The vehicle wouldn't come out of first gear. This was the result of the vehicle being shipped without transmission fluid. The transmission had to be replaced.”
NHTSA complaint #10044012, filed 2003-10, 42,416 miles“Transmission went out at around 44000 miles. Dealer said the "lip seal" failed inside transmission, after taking it in several times for diagnosis. Would not assist with repair cost. Ended up having it repaired at aamco. A/c is currently out on the low setting (#1). Not yet repaired. Just repaired the cooling system. Dealer said it was an internal leak. Van kept getting low on coolant, had to keep filling it up, however never saw a leak. Dealer said problem with the manifold, and coolant was leaking thru and being evaportated, therefore no telltale leak. …”
NHTSA complaint #10070207, filed 2004-01, 44,000 miles“The contact owns a 2000 Pontiac Montana. The contact started the ignition and the gear selector would not shift into any desired gear. A certified mechanic inspected the vehicle at the failure location. The gear cable was replaced. The VIN was unavailable. The failure mileage was 122,000. Updated 11/03/10.”
NHTSA complaint #10346988, filed 2010-08, 122,000 miles“We have repeatedly reported to both the dealer and the mfr. That when our transmission is in drive, our vehicle rolls backward even if only on a slight incline. It also rolls forward when in reverse. When the incline is steep, you are fighting to keep going in the direction the transmission is in gear. It is as if we have a manual transmission with a clutch. It is dangerous if someone is in front of us when we are trying to back up or vice versa. I have never had a vehicle like this. I have test driven other manufacturer's vans and it never happens. …”
