I was driving down the city road and my car just shut off and lost all power to everything. I almost got hit. I then turned my car back on and the service stability trac light came on and the check engine light was flashing. I could nearly get it to go at all and my car was shaking and sputtering. It was the scariest thing I have ever dealt with. I had it put in the shop on 10/26/2018 and now it just happened to me again and its 03/26/2020.

The car was very noisy at start up. Had the oil changed, the noise was better for a while but came back in less than 2 months and now it is constant. The car will stall out in the middle of driving. I will lose everything, electrical and power steering. This would happen whether or not on a highway or during city driving. Engine light came on and I took it to my mechanic. Mechanic told me it was in reduce power mode. Camshaft coralation code.

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.

Check engine light on. Code p0011 present. Indicating over-advanced camshaft position sensor. While performing a u-turn, the vehicle died/lost engine power and steering locked in place in the middle of the road. The vehicle was spread across three lanes, as I was in the middle of my u-turn, with oncoming traffic approaching. Luckily, I was able to start the car back up and regain control just as traffic neared my position. Almost deadly situation. Also noticing engine hesitation as well as shaking of the vehicle while idling.

Bought my car from a reputable dealer. The car was a fun toy for me to drive. My 2011 regal apparently had has a transmission problem. The shop says needs a new transmission because everything is sealed and can't be serviced. Anyway multiple times I'm on the road and in town and the car drives okay, but as soon as merge onto the high way the car stalls. Heres what happens as soon as I merge onto the high way the RPM's go way up. The trassmission is stalled.the car won't accelerate. Multiple times I've almost had an accident. The instrument cluster has "d" flashing and engine light is off. I pull over the side of the road turn the car off, and then restart the car and then it works again. This sucks. It honestly a 50 50 chance the car transmission will stall when I merge onto the highway. I feel this is a recall issue. Manny people have complained about this recently around the same millage of mine. Around 100,000 miles. Only problem is buick takes blame on the same problem with the enclave,but not the regal. What a shame.

I'm writing about a concern I have regarding the transmission design for the 2011 buick regal. I purchased my car from a reputable dealer with a clean car fax in 2014. The car had roughly 45,000 miles on it, and every bit of maintenance has been performed at the appropriate intervals since I purchased it 3.5 years ago. During the time that I've owned my car, I have put an additional 30,000 miles on it total. I haven't driven it on the highway since july of 2015, and my trips are shorter than 4 miles one way. On my way to work a couple of weeks ago, my transmission completely failed without warning. I was almost broadsided twice, turning left around a roundabout. I was driving roughly 30mph, and without warning it lost power. The "check engine" light flashed, and the car stalled trying to switch gears as I accelerated. When I went to put it in park, it will slide into reverse but doesn't move in any direction. I was forced to push it uphill in a parking garage, so my tow truck driver could come and tow it to my mechanic. I had it towed to my mechanic, who informed me that this design has a fatal design flaw causing the transmission to fail. The enclave has been recalled as well for exact same failure. I then got a second opinion from his transmission expert, who was dumbfounded I was needing to replace a transmission in a car that has accumulated 30,000 miles total in 4 years time. Both my mechanic and my transmission expert informed me that the enclave had been recalled for the exact same failure, and they personally knew of buick regal owners who had their transmissions fail without warning. If I had been going faster than 30mph, or been on the highway, it could have been fatal! I spoke with my attorney, who advised me to file complaints with buick, the ftc, and the federal safety agency.

Last nite, 9:30 pm we came out of publix parking lot doing an easy left. The engine shut off, all lights lit up on dash and center console lit up saying "lower driver window.." followed by "lower passenger window"!! We coasted to side of road, put it in park then it started and we got home. This morning, a easy right onto highway and locks opened and closed by themselves at about 30 MPH! During the hwy drive, at 75mph car stutters, engine whines then catches itself, all dash lights come on and the engine light blinks 3 times then goes out! What the he**.. Could have died!
