“I started my car and while I was in park the speedometer said 70mph. While I was driving it would register over 120mph. I had no idea what speed I was truly going. This is a scary feeling especially with my three children in the car. I tried turning off the car putting it in drive and back to park thinking perhaps it was stuck, but nothing works. I see this is a common problem...help??”
NHTSA complaint #10607635, filed 2014-07, 164,020 miles“First the airbag warning light came on. This has been an ongoing issue since 2008. My speedometer registered the wrong speed. My settings for the seat and mirrors quit working over time.hot air would come out of my vents when the air conditioner was on randomly. Radio, navigation, heat, air conditioner and mirrors would turn on/off randomly without touching controls. The last 3 years went through 3 batteries in 3 years. Tests showed at least 5 things are actively draining battery in the fuse box. …”
NHTSA complaint #10954363, filed 2017-02, 32,000 miles“At approximately 1:54 pm I was leaving work and I didn't get about 1,000 feet when I began to see smoke coming from the center console area where the cigarette lighter was. I pulled over into a gas station and took the cup holders out trying to search where the smoke was coming from. I then saw smoke coming from the vents on the dashboard. I also saw smoke coming from the battery compartment under the hood. I opened the hood and more smoke with coming from the vent. …”
NHTSA complaint #10629134, filed 2014-08, 136,000 miles“In the instrument cluster on my 2004 Gmc yukon, the speedometer hangs up indicating a higher speed than actually traveling. Initially, the problem occurred at intervals greater than 6 months but seems to be recurring much more frequently - every 2 weeks or so. Upon initial problem being noticed, I found that other model year yukons had this issue and were repaired, possibly under recall but my model year was excluded.”
NHTSA complaint #10253806, filed 2009-01, 60,000 miles“First my oil gauge started giving false readings on my 2004 Gmc denali, I could live with that. Then my speedometer readings are all over the place...all the time with different readings. I am scared for my safety and the safety of others. From reading online this is a very common problem on Gmc vehicles and I feel something should be done by Gmc to remedy the problem!!!”
