problem #3

Rainier 6-cyl

  • Automatic transmission
  • 37,200 miles
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.

- West Chester, OH, USA

problem #2

Jun 202007

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.

- Fort Walton Beach, FL, USA

problem #1

Rainier 8-cyl

  • Automatic transmission
  • 2,600 miles
Transmission leaking, shifting hard, revving high during shifting, and 'hunting' for gears while traveling.

- Appleton, WI, USA
