I have more then one issue. First important issue. While driving down a state road with a peed limit of 50 at 50 MPH. My car lost power check engine light came on and the warning light says engine reduced power all acceleration was lost was able to drive at about 30 and was close to a repair shop so got ther they diagnosed a throttle seal. Fixed and repaired december 30, 2016. 6/14/2017 while driving at 35 MPH the same thing happened again. I have returned to the shop and discussed with gm service center they say no special notice about this issue but I see numerous complaints about the same issue in forums on line. Issue 2. The lights on the dash speed, warning info, radio light dim for no reason. Issue 3 door locks do not work from key fob or inside car have to work manually the passenger side air bag turns off even when some one in the seat. I have had this repaired once but continues to to this

While driving, the engine light came on, followed shortly thereafter by the traction control light.then the engine began to lose power and the accelerator pedal did not work. A notice appeared on the dash control: "engine power reduced" and "service traction control". If I held the accelerator pedal down all the way to the floor, after about 5 seconds the car began to accelerate quickly. I could then maintain speed by alternately stepping on and releasing the accelerator pedal quickly. Accelerating from a stoplight is a very slow and disruptive (to traffic) process. This has happened multiple times and has failed several attempts at repair. On some occasions, the car has begun to accelerate on its own during this period of malfunction, such that I have had to ride the brake pedal. On some occasions this problem has remedied itself after a couple of days, with turning the engine on and off to reboot. The problem can last for days at a time. I have replaced the throttle body sensor to no avail. Interestingly, I also owned (until last week) a 2007 lacrosse which does the exact same thing, and has also had the throttle body sensor replaced with no luck. I have seen multiple descriptions of this by people online, describing exactly the same conditions and warnings. This is a significant safety issue when it happens, as I cannot safely accelerate in busy traffic, and the car slows down to speeds unsafe for the conditions. I find it difficult to believe gm does not know about this, in that I have had the same problem with 2 lacrosses. Thank you.

There is a the federal safety agency service bulletin id # 10024713 related to a power steering leak caused by a defective part or design. The bulletin recommends a tie down strap to prevent hose wear and resulting leakage of fluid. Loss of power steering and/or damage to the power steering unit can result from this leak. I believe buick has been aware of this problem for some time. I question why gm did not recall all vehicles with this problem to replace the worn hose and attach a tie down strap before leakage was found. Loss of power steering can be a safety issue, as seen with the current ignition recalls. Gm is not providing any extended warranty on this defect.

While driving north on alternate 69 highway at 65 MPH at 5:00 p.m., my vehicle abruptly loss power even though I tried to accelerate. The engine shut off suddenly and without warning. Vehicle slowed to a complete stop. I was driving in the middle lane and was unable to get in the shoulder lane because I had no pickup (unable to give gas to accelerate) so my husband and I were caught in five 5:00 traffic with cars whipping around us on both sides and many exceeding 65 MPH. I put on my emergency lights and immediately called on-star. I was unable to restart the engine. Thank god for on-star because from that point on, I was in terror witnessing cars coming upon us not slowing until they realized I was at a stand still with lights flashing. The cars would swerve to keep from hitting us. It took the highway patrol and police 15 minutes to get to us but during that time, I relived visions of us being killed on the highway. I can't describe the horror, looking out my rear view mirror, witnessing our demise time after time. Those 15 minutes seemed like an eternity. When the highway patrol arrived they closed lanes and assisted in pushing car out of the highly traffic lanes. It took my husband and I both to turn the steering while in neutral. The car was towed to conklin fangman kc dealership and I had to replace ignition coil and module that cost me $933.16. They said these parts were not on the recall list, which I have found out since then gm has put dealerships on notice of this problem. It has something to do with supplying enough manufactured parts to take care of recall. If I could afford to purchase another car I would because I don't feel safe any longer in this car. Emotionally I am still suffering from the trauma.

The ignition control module (not the ignition switch) failed suddenly while driving on the highway, causing the engine to shut off suddenly and without warning. The car was traveling downhill, so the initial indication was loss of power steering. I was able to pull onto the shoulder and then realized that the engine had died and would not restart. While no crash or injury occurred, the potential for a serious crash was quite high.
