2007 Buick Lucerne Other or unknown Problems

“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.”

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. …”

“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. …”

“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. …”
