Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When I start the truck in the morning it sounds like the engine is revved up with the loud fan noise. I had the fan clutch replaced independently and the loud noise continues and a slight loss of power at times while driving and it feels like it's taking too long shift into the next gear. The noise is really heard when you accelerate on the gas pedal.”
NHTSA complaint #10441170, filed 2011-12, 147,378 miles“I just experienced a safety defect that could have had very serious consequences. It involves the failure of the shift cable attachment to the transmission mounted shift lever. You unknowingly loose the ability to place the transmission into the park position, with the resulting vehicle movement of an apparently parked vehicle. Please contact me asap. -- thanks”
NHTSA complaint #10291318, filed 2009-11, 82,000 miles“I have a 2002 Gmc Envoy which has a destroyed transmission due to the well known (but unbeknownst to me) failure of the transmission cooling lines. This is a clear design flaw, as the routing is close to the catalyst. Besides the obvious safety concerns of an on the road transmission failure, the location makes a fire likely. The design flaw is documented in TSB pt-4722. I believe these vehicles should be recalled.”
NHTSA complaint #10282945, filed 2009-09, 153,000 miles“I own a 2002 Gmc Envoy with 70,000 miles on it. Went to drive to the store and the truck would not move. There is a wining/ spinning sound coming from the transmission. Reverse works, but all others do not. I have read quite a few forums on this topic and found this problem happens often. Please let me know want I could do about this.”
NHTSA complaint #10137672, filed 2005-09, 70,000 miles“Manufacture knew of inferior components within my vehicles transmission and did not issue a recall. Existing service bulletin #00-07-30-022c dated dec 10, 2004 (within my warranty period) indicates same issue I experienced in my vehicle on 10/23/2007. Bulletin title states replace reaction sun shell with more robust heat treated parts . This was known while my vehicle was still under warranty. Failure happened after standard warranty expired.”
