While the vehicle was driving, there was a loss of power, at that moment sparks was seen emanating from under the hood, then the vehicle completely stopped running. Once pulled over smoke was bellowing out from the hood and subsequently ignited into flames. Fire department was dispatched and fire was extinguished. The vehicle was towed away and is still at the tow yard. The tow operator, based on visual inspection stated the fire did start in the engine compartment and spread to the fire wall, totaling the vehicle.

The oil consumption in the car is horrible, I have to atleat add oil in my car about 5 time in between oil changes, and my oil changes are done regularly, ive also have the issue of my oil and gas mixing, I did take it to the shop once and they fixed a recall that was involved with high pressure fuel pump, but im guessing they didnt fix the issue once that repair was done like they said it would.

I noticed that the car was resisting acceleration a little bit, have 48,545 miles on it and took it for oil change with fuel injection cleaner and full tank of good gas. Got on highway and the acceleration died completely and no gas was getting through, like flooring it in neutral. Pulled off the side and it restarted but continued dying along the way if I try to accelerate.

Reference the below background information on GM's L4 - 2.4L 4 cylinder engines: Please reference document id: 4821148 #12313D: Special coverage - engine balance chain and fuel pump - (June 6, 2017) this special coverage bulletin was provided by my mechanic at midas from the alldatapro.com website. Special extended warranty repairs are supposed to be covered via this bulletin for 120,000 miles or 10 years for GM vehicles that have the L4 engine including the 2011 Buick Regal. My 2011 Buick Regal is definitely exhibiting all symptoms / problems that are well known with the General Motors L4 - 2.4 L four cylinder engine. See information below about oil consumption and engine performance symptoms: Https://www.msn.com/en-us/autos/research/seven-engines-to-avoid-like-the-plague/ar-aavz7vm#page=3 I am a former GM powertrain division engineering / salaried employee where I had a 20 year career background with engines and transmissions. The L4-2.4L engine is a known safety hazard as the engine can fail while under normal operation on a highway or city street with potential catastrophic results. Even with the mechanic oe bulletin referenced above, GM refuses to cover expenses for permanent repairs for the 2011 Buick Regal. Instead dealership customer service representatives are instructing vehicle owners to just add oil frequently. (note: The low oil indicator is also defective.) please also reference the class action law suit below: Https://www.classaction.org/media/berman-et-al-V-general-motors-llc-joint-notice-of-settlement.pdf GM corporation customer service, professional mechanics, and GM's dealership network (Buick and Cadillac) all are fully aware of the catastrophic safety consequences that this engine poses to the general public; yet, a comprehensive recall and appropriate extended warranty coverage is being denied.

Nyb car has less than 69K miles and is burning through oil. I bought it used and the dealer liked warranty ended before problems started. My check engine light came on within the first 2000 miles of me driving and the dealer wanted to charge me another $200 for a diagnostic. So I went to a mechanic and he said the engine was burning through oil faster than it should. At this point the car had turned off while under 10mph twice which is dangerous as the brakes lock up along with steering becoming very stiff. A mechanic did work on the car replacing plugs and other parts that had been damaged fue to the oil being gone, but the same engine is still in the car. Now less than a year later along with regular oil changes the car still burns through oil. The engine causes the car to rock when at idle and when moving under 5mph. My fear is that ive car will shut off again. This is a fault of Buick for designing an engine that can't hold oil.

Takata recall - my Regal is 2011. I have not had any problems prior to this. My service stabilitrak ligh began coming on along with ABS light. I also explained the check engine light would come on after filling the tank and it reduced to 3/4 of tank. Last week all lights came in on car as I was parking. Took the car into to be serviced. The dealer completed a diagnosis advising I had a leak from my fuel pump. Needed new fuel pump, fuel injectors. For the ABS problem needed new bearings and sensors. I drove away for second opinion. The next day while driving slowed for a traffic light and pressed gas to take off the car would not accelerate. The engine was running. I had to turn car on and back off to get to move to the center of the road during rush hour. I sat there for a min. Was able crack and get to a safe place off the major road. I got a second opinion having the car towed to Firestone. They also saw a fuel pump code and mentioned the timing chain. I had car towed to the dealer. They replaced the fuel pump on my way home on the interstate. I slowed for the exit and hit the gas. The car stalled again. I was afraid at that point. The dealer cannot tell me what the exact issue is with the car. It is still there for diagnostic now. They had to escalate and still no answer. They are using trial and error to resolve the issue which is a dangerous and expensive joke.

I have owned my Regal since 2011. As I accelerate the car would shudder and shake, then I would get a service stabilli trac message followed by a message stating that the engine power has been reduced. After I have the issue it will reset itself after restarting and then will run fine for a while. I called on star on several occasions and they told me that it has an engine misfire or the stability trac needs to be serviced or the electronic throttle body is malfunctioning. I have taken the car to the dealer and they tried to fix without any luck. I think part of the trouble with fixing it is the fact that the computer resets itself and therefore they can't find a code. The other issue with trying to fix is the fact that the car only has the issue when it is 35-40 degrees outside and below. Other issues I have had, driver's seat heater not working, outside trunk release not working, passenger side seat belt does not connect properly and of course the recalls for the driver's seat bolt and exterior turn signals. Now for the bad news for myself is that the car is out of warranty. Given the fact that I have read many similar complaints and most of them not being resolved, I find it very hard to bring myself to take it to the dealer and have them guess to what the fix may be at my expense.

Vehicle continually stalled and died at red lights, stop signs, or when slowing for turning vehicles. Took vehicle to dealership and was told that it was not serious and was scheduled for repair 2 days later. Diagnosed as camshaft indicator. Current recall outstanding on some 2011 Buick Regals but not all. However, based on research on Buick service website, it appears to be widespread problem and was dangerous considering my vehicle died at an exit ramp leaving the interstate.

When I filled the Buick Regal with gas and at speeds 45mph and up, you start to smell gas fumes inside the vehicle. It's cold out so the windows are up and on two occasions, after I got to work I was dizzy and light-headed and my heart was pounding. Two co-workers wouldn't leave my side until my head cleared. They thought I was having a heart attack or something, but my heart and head finally cleared. I'm scared to drive it and I work an hour away and may cause an accident.
