2004 Buick Rainier Vehicle speed control Problems

“While I was driving down a rural road doing about 35 to 40 MPH the speed suddenly froze at 40 and it no longer moves. I'm currently a driver for the city and this is a complete hazard when driving and can't determine your speed. I was very afraid due to the fact I couldn't understand why this happen to me which occurred in the process of acceleration . When I finally looked down my speed said 90 which I knew for a fact I wasn't going that fast at all once the vehicle got stuck on 40 it never came back down. …”

“Driving on a city street- speed limit of 35 MPH my meter read 75 MPH. I put my GPS system on to monitor my MPH. At traffic light while idling the meter read 45 MPH. 2004 Buick Rainier had been sitting outside for 3 days with the temperature in the 20's and this was the 1st time I had driven it. Tried accelerating and stopping a little suddenly hoping to jolt the meter back to normal. No results. Parked for about 30 minutes, started the car and it began to register at 65 MPH when driving 35 MPH per GPS. Idling read 25 MPH. …”

“I was in the midst of a 10 hour road trip over the holidays when the speedometer originally quit working. I was traveling at a rate of 70 MPH.

I continued on w/my trip and took the car to the dealership upon arrival in abilene, ks. They were not able to identify the problem in the cluster and checked bulletins for past problems w/speedometers. …”

“My husband and I purchased a used 2004 Buick Rainier with 33,000 miles last may 2008. One evening during the summer we were making a 20 minute trip and the speedometer just stopped working while en route. Since then the speedometer gets stuck while making 20+ minute trips and will only go down 5 MPH each time you shut off the SUV and restart. So you have to shut off and restart several times before it reaches back down to zero and it will then operate okay for a little while until you make that 20+ minute trip again. Sometimes while just driving around town running errands it will get stuck. …”
