2007 GMC Yukon Owner Comments

problem #3

Aug 182007

Yukon 8-cyl

  • Automatic transmission
  • 10,229 miles


The contact owns a 2007 GMC Yukon. While driving at highway speeds or lower, the transmission shifts very hard. There is also a harsh pounding sound coming from the transmission. All of the electrical components on the instrument panel failed. The dealer changed the crankshaft sensor. While driving, the contact cannot tell when the gear is in neutral. The speedometer displays inaccurate speeds and the air bag light illuminates. The plastic on the window fell off and the front driver's side door handle sticks when it is pulled, and will not go back in. The contact hears a rubbing sound coming from the steering column. The instrument panel cluster has been replaced and the check engine light would remain illuminated. The current mileage was 29,000 and failure mileage was 10,229. Update 09/10/08 the lug nut caps were missing, the check engine light was on. The gas cap was not sealing. The dealer replaced the gas cap. Updated 09/15/08.

This new vehicle has shifting problems. Sometimes the rpms will reverse when you stomp on the gas. It doesn't respond. This is a safety issue in that if you pull out into traffic, you may or may not get the acceleration needed to avoid impact. The transmission goes crazy. The local GMC certified repair service tech said that they have been instructed not to try to work on the system. GMC is aware of the problem, but there are no solutions. It will actually miss and loose RPM's when you accelerate in mountain terrains. It is only somewhat reliable in highway travel that is flat. Someone is going to get killed soon if not addressed immediately.

Yukon 4WD 8-cyl

  • Automatic transmission
  • 20,000 miles
Driving at about 20 miles per hour, excelled to get past another vehicle and the vehicle basically stopped, threw us(kids, myself) back, almost in a whiplash type manner. As I tried to excel the engine just revved and the car would not move. I put into 3rd, but when I made a stop I had to put into 2nd. Stopped again, had to go to first, wouldn't move in any other gear and barely in first. I was near the dealer thank goodness and pulled in there.
