Engine Shut Off Without Warning Problems of Buick Lucerne

This car just shuts down while driving. This is very serious as you lose your power steering and brakes. It has happened 3 times in the last month. Someone is going to get killed! I took it to mechanic first time he tightened a battery wire. It did start back up but died going down the road and towed it back. He then tightened wire on ignition module. It started and ran a few days and did it again. It now did it a third time. It throws no codes on the car so it is very difficult to diagnose. I have seen numerous other people have this problem.

This 2006 Lucerne engine shuts off while in motion without warning. It has shut off four times this year and two times last year. The last time it shut off, was April 11, 2017 5:00 pm central standard time on a busy city street. My wife is not strong enough to steer this car when the engine shuts down. When she had restarted the engine she was so nervous until she accidentally turned the wrong way onto a busy by-pass.

This car's engine would stop for no reason and not restart at stop signs and while driving. The power steering and power brakes would go out when this would happen which was especially dangerous when driving. It was taken to the dealership for repairs on at least 4 occasions and never fixed. It is again listed on the dealership site for sale after I took a $3,000 loss trading it in for another vehicle. I was told by the manager that the car would not be sold again, but it is on the pre-auction lot of the dealership for sale at nearly the amount I paid for the vehicle in November 2016. It was driven about 2,000 miles in the 6 months I owned it because most of the time it was broken down. It sat in the dealership lot for the last 2 months because I was told that there was "nothing wrong with your car. " I traded it in rather than have an accident where either myself or someone else may be hurt or killed due to the lack of ability to control the car when the engine shut down. The car fax for this vehicle can be seen on line with some of the repairs that were completed during the time I owned it. The repairs were for various sensors; one of them was replaced more than once. I was instructed to by one of the service managers to have the car "totaled" by the insurance company because they wouldn't be able to figure out what was wrong with the car unless it stopped running while they were working on it. I had a video of the engine stopping which showed that there was no warning. I made it because I was being asked what lights came on, etc. , before it shut down. The video was shown to the service manager, but it was useless as the car engine again stopped for no reason. It first broke down three days after I had purchased the car, but beyond the "no questions asked" return policy of having less than 150 miles on the car due to my having driven it over 200 miles.

Tl- the contact owns a 2008 Buick Lucerne. The contact stated that when making a turn, the vehicle shut down. Also while driving over a puddle, the water got into the engine and caused the engine to momentarily shut down. There was no warning. The vehicle was taken to the garber Buick GMC dealer (772-467-0835, located at 5255 us-1, fort pierce, FL 34982) where the technician was unable to diagnose the failure. The manufacturer was made aware of the failure and told the same dealer to perform a diagnostic test. The contact did not want to be financially responsible for the diagnostic test, so the failure was not diagnosed. The vehicle was not repaired. The failure mileage was approximately 5,000. Fe.
