Welcome
There has never been an official recall from General Motors regarding widespread speedometer problems, but a 2007 class action settlement qualifies certain owners for a special coverage adjustment (Special Policy Adjustment 07187a) to their standard warranty for allegedly defective speedometers.
Common symptoms include:
- Speedometer displays incorrectly
- Speedometer stops working
- Tachometer needle sticks, jumps, or pegs
- Fuel gauge flutters
- Entire instrument panel fails
The common cause for all these issues is a faulty stepper motor (XC5.168). The motor was used throughout General Motor’s entire production line from 2003 to 2007. For those with a technical bent, this includes the GMT800, K20, GM360, and GMX380 platforms.
Models effected include (click link to determine qualifying status):
- Buick LeSabre
- Buick Rendezvous
- Chevy Avalanche
- Chevy Silverado
- Chevy Suburban
- Chevy Tahoe
- Chevy Impala
- Chevy Trailblazer
- Chevy Monte Carlo
- GMC Yukon
- GMC Yukon XL
- GMC Sierra
