While vehicle was in motion on a city street,approximately 5 days ago and also 1 month prior to this it unexpectedly reduced power and within 5 seconds completely shut down the vehicle!if I was on a parkway or interstate when this occurred it could have resulted in a serious crash.my wife will no longer drive this car for fear it will cause a terrible or fatal accident.the vehicles dash read "starting disabled"service throttle!took it to the local dealer for evaluation and they could not find a solution.this a very serious safety issue that needs corrected before someone is injured or killed.this car only has 36k miles on it.

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.

Around or about october 2011, while traveling at approximately 40 MPH, my 2007 buick lucerne's engine suddenly shut off. This caused the loss of power steering and brakes (and airbag?). Fortunately, I was on a secondary road and managed to get the vehicle to the side of the road without any problem. Initial efforts to restart the vehicle were unsuccessful, so I called aaa for assistance. After about 15 minutes, and before aaa arrived, I was able to restart the car and drove home (it was a sunday). The next day I drove the car to the dealership where I had purchased it (new) just over five years before (it was just out of warranty). After what I was told was a complete check, no apparent reason for the engine quitting could be found. I drove the car home and around town for several days, when the same thing happened again. This time when I took the car to the dealership I told my service consultant that I refused to drive the car, which I occasionally used to transport my young grandchildren, until the problem had been diagnosed and repaired. We agreed that one of the mechanics could use it for his personal use until the problem reoccurred. And it did. A few days later the dealership informed me that the car had again stalled, that the problem had been diagnosed, and that there would be no charge when I picked up the vehicle. The problem, I was told, was "in a computer" that had been replaced. I drove the car for several months after that (before selling it), and the problem did not reoccur. I brought this to the attention of both general motors and on-star (the latter, just in case the shutdowns had been prompted by that system) and nobody would acknowledge that similar incidents with buicks had occurred: and they still won't. A cursory search of the internet shows similar problems with other buicks, yet they are not included in any recalls. Why not? Thank you.

While driving at 55-60 MPH in 5:00 p.m. Baton rouge, la traffic on joor road, I heard the doors automatically lock, then the engine died, I lost power including steering, brakes, and almost caused a terrible pile-up as my car stopped in heavy traffic. I had no ability to steer, brake, no power. I was at the mercy of god and this dead car, praying that no one was killed. I eventually was able to coast to a stop. Other vehicles were able to move to other lanes, abandoning me to the right hand lane of traffic. I called onstar and they should have the recording of the conversation, the terror I was in, and their instructions. I have 4 recorded incidences of the repetitive nature of this vehicle malfunction. I can provide details of all incidences, follow-ups with gm, and eventually having to payoff the piece of "junk" at a loss of over $20,000. My last gm purchase. I have since been driving toyotas. My experiences with gm management was horrific.
