This electrical problem began about the first of the year when the electric door locks started to cycle while driving. It has since migrated to turning off the cruise control and causing the headlights to flash off and on. The remote start will start the car but will shut down the motor after a few seconds. These problems continue during every operation. I have been informed by the dealer that it is a p140 code and will take about 3 to 4 hours to diagnose where the problem at $80.00 per hr. Plus repair.

On 4 separate occasions my '06 buick lucerne (3.8 l)went into uncontrolable excelleration. On long road trips, with the cruise control engaged and doing approximately 70 MPH, when I excelleratedhard, instead of returning to the cruise speed it seemed to lock into a passing gear. Braking didn't stop it, putting it into did not slow the engine revs., however turning off the key and restarting after coasting a little while worked once or twice to stop the revs.. The other times I hit the brakes really hard and it disengaged the cruise and excelleration problem. Fortunately there was no accident or damage, since I had room on the highway to do this. The buick dealer where I bought the car said they never heard of this before and could not duplicate when they tried. There was approximately 60,000 miles on the car when the last incident ocurred. Ps turning off the cruise switch didn't help either.

I purchased a new 2006 buick lucerne cxl in 2006. I have numerous times experienced acceleration in my vehicle. I have taken it to a buick dealer and they drove it and say they didn't notice it. I have also talked to a gmc dealer in the last several years and asked it anyone else has had a vehicle that just speeds up on it's own. I am from a very small town in missouri and 3 other people have purchased the same buick lucerne as mine and one of them says he thinks his vehicle may have sped up before, but he thinks he may have let the cruise control on. The first time this vehicle did this to me was on my way to the lake of the ozarks. I come from a small town there is really no where that I can use the cruise control except on larger trips. We have a lot of hills and curves. Going to the lake of the ozarks the speed limit is 70. I used the cruise control. I got behind a trailer that was going very slow and traffic was a little busy, so I applied the brakes and when traffic was clear I passed the trailer. I was going to resume the cruise control, but before I even touched the button, my car took off and I was at 93 miles an hour and I hit the brake and it would not stop. I then tapped the brakes several times quickly and it started to slow down. When I got the speed down to 55, I then applied my foot back to the gas pedal and when I did, the gas pedal was not down or stuck, but I could feel a little something in it. This is something you do not feel in it all the time. I tried to figure out what happened and told my husband about it and he said you must has hit something wrong. I said no I'm telling you it did it on it's own. I go to work at 4:00 am in the morning. Where I live there is a lot of deer, so I do not drive fast for about 3 miles to work. One morning I was driving on a straight stretch and when I came to about the top of a little hill my car again did the same thing. It just takes off and it catches you off guard.

Dash instruments and gauges are not visible in daytime. Run off road trying to see speedometer to set cruise control. Dash lights are completely off in daylight, making it impossible to see dash instruments. Contacted dealer and was told that there is nothing they can do. Contacted gm and they tell me that it is a design flaw and it is not covered by warranty. I have found out that others have had same problem. It is on buick lucerne 2006, also understand 2007's have same problem. It is not on all cars as I understand it. It is dangerous to operate car. May cause to run off road or cross center and have wreck trying to figure out what speed car is going. Needs to be fixed.

Dt*: the contact stated while setting the cruise control the vehicle surges forward 5 to 7 MPH. Due to this problem the vehicle takes 15 to 30 seconds to return to the set speed.

The light to illuminate the instrument panel were not bright enough.
