Car drains my battery and it messed up my alternator. I replaced both and once again my battery keeps being drained. I took it to the shop and the mechanic ran a diagnostic test and about 10 codes popped up saying electrical problem. Other models of this Buick has been recalled for the same electrical problem. Il drive my car and it will completely cut off on me and the check engine light comes on. Il find my paper work from the mechanic if needed. This has been happening for months now. It didnt happen just once. So I cant drive the car until its fixed.

My altenator stopped working and after it was replaced my fuse box would not read nor would my car crank. So I had it towed to a Buick dealership where I thought all of my problems would be solved. They replace my fuse box with a used one because the box has been discontinued this was in April 2017 it is now May 2017 and I've had a diagnostic tes ran on it because my fans stopped working causing my nothstar motor to overheat. The diagnostic determined that fuse box is what's causing all of my problems. Every code led straight to that same fuse box. My vehichel was on and stationary when all of a sudden my power steering connector cracked and all of my fluids started to leak out from a result of overheating and the connectors being made of plastic and basically wearing from the heat.

Vehicle is a 2006 Buick Lucerne cx with 40,000 miles. About 2 months ago it started to go dead without any warning. The first occurrence was Jan 15, 2014 with my wife driving. The next shutdown on Mar 4, 2014, occurred in rush hour traffic. There was an audible signal accompanied by a "service traction control" warning, followed immediately by a throttle control warning and complete engine shutdown. I was able to coast across 2 traffic lanes into a parking area with great difficulty while steering and braking without power assist. Tried to restart the engine but got "throttle disabled? message. After 2-4 minutes was able to restart with no warning light illuminated. The last shutdown was on March 10, 2014, on the interstate at 70 mph. I had disabled traction control earlier in hopes of avoiding another unexpected shutdown. After coasting off the interstate, I was able to restart normally after a few minutes. No warning lights appeared after the restart. Two GM dealers checked the car on Mar 11, 2014. The first was a Chevrolet dealer, and after some diagnostic work they sent me to a Buick dealer down the street. Both dealers said there were no error messages and they could not repair. They said when it happens again to bring it back in immediately for diagnosis. The 3 shutdowns have been on cold mornings, temps less than 40 degrees. I believe in all three cases the warning ?watch for icy conditions" has appeared prior to failure. This is an extremely dangerous failure mode that leaves no tracks if there is an accident! my wife now refuses to drive the car, and I am very apprehensive about it.

The warning light came on and stated service stabilitrac and then went off.two weeks later came on again, and went off.the car began to shake and vibrate as brakes were applied when stopping.about a month after that the traction control light came on and the car began applying the brakes at a speed of about 50 miles per hour and making a noise that was loud enough to hear as it sounded like the pressing of the brakes to the wheel hubs.my wife and daughter and I turned around went back home and parked the car and drove my truck to visit other family members that day.two weeks later I took the Buick 2006 Lucerne to have a GM certified mech put it on the diagnostic machine and the reported that nothing showed up as needing replaced.

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 per hr. Plus repair.

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.
