Vehicle stalls unexpectedly while driving and while it's just sitting. There is absolutely no warning sign as to when this will happen. It's stalled on me while driving in all weather conditions and at different speeds. The engine just quits. Sometimes it will restart after a short while, and at other times it's had to be towed. We've had it to different dealers and mechanics and no one can figure it out. Can't drive or sell it in this condition. The same problems occurred when my father owned the car. He took it in several times for repair also, and again, nothing solved the problem.

Head light failure due to passenger side relay harness module failure. Low beam lights failed on dark night on mountain road. This problem has been reported by numerous Buick Lucerne drivers. Buick obviously knows there is a problem because they offer a replacement front light harness module that must be spliced into the existing main light harness to replace the original equipment module. This is an obvious manufacturing design defect and a difficult module to replace. The replacement module is approximately $50 and the replacement labor is around 1.5 hours. With normal use this light module connections shorts out because of the overload on the module. Why hasn't this problem been considered for a recall? GM has admitted it is a design defect with the availability of the replacement light harness module wiring kit. My wife almost went off the road and wrecked when the lights went out.

Problems : a short circuit on the printed circuit board for the washer fluid heater, overheating the ground circuit board. May cause other electrical features malfunction, create an odor or cause smoke increasing the risk of fire. 2. hwfs harness. Considerable melting has occurred around the hwfs fluid chamber. Possible for the heater washers module to ignite and a fire may occur. 3.on 3 occasions the key has locked out of the run position and caused loss of power, power-steering, and power breaking; increasing the risk of a vehicle crash. I have contacted Buick about this. They stated there are no recalls on my vehicle. Customer complaint number is 8-2700897169. General service number 1-866-608-8080. I drive as little as possible because of the factors. 1st recall # 08V441000 recall date 08/28/2008. Componet: Electrical system on all 3 issues. 2. recall date 06/24/2010 recall #10V240000. 3. recall number is 14V355000 recall date 06/23/2014. Buick states these are not issues with my car but all these issues have occurred by me. These incidents for some reason these all happened while the vehicle was stopped at a traffic light, fixing to stop, or starting from a low rate of speed.

Leased Buick Lucerne 2007, nothing was wrong when I got it and they told me there was a recall on the car but it was fixed, but then 5 weeks later my car won't start...they put a fake recall inspection sticker on the car, they told me "don't put anything on the key...now they want me to pay for the payments, deductible, and diagnostic fee...

Dash cluster is very hard to read during daylight hours unless backlit by light sensor on the dash. During the day the dash cluster is almost impossible to see and read with or without sun glasses. I have to take my eyes off of the road for more than 2 seconds to see my speed, tack, gas gauge or other accessories, which takes my concentration away from driving and could result in a serious accident. I have had the car back to the dealer suss Pontiac twice. First time they replaced the entire cluster. The second time was for the same reason. The dash cluster cannot be read during daylight hours. The second time back I was told by the dealer and Buick there was nothing they could do about it, that I would have to put up with this problem. The dealer admitted that others have also complained of this exact same problem. If I cover the light sensor on top of the dash, then the night-time lights will come on and I can see, but this dims the radio so that it can't be read. Covering the light sensor is not a solution to this problem. Buick needs to make the face of the dash cluster any other color than dark blue or back light it. The service request number with Buick was 71-849515366.
