Rainier 6-cyl

  • Automatic transmission

There seems to be a known safety issue with speedometer control module. The dealers know about this issue, transmission and speedometer repair shops knpw about this issue. This is a very dangerous problem as you are driving and the speed registers different & sometimes not at all.

problem #2

Rainier 6-cyl

  • Automatic transmission
  • 46,403 miles
At 46,403 miles I noticed that the engine would rev up more than normal when shifting gears. Took into the Buick dealer and upon inspection the tech found that there was scoring in the valve body of the transmission. Extended warranty took care of the issue however I was told that this was rare for raniers.
