Timing chain loosened due to tensioner breaking due to the bolt holding it in place widening the hole it was in over time causing the car to jump time and possibly bending all the valves in the motor. Car was being driven on the highway when it stalled and shut off. We had just made a turn so luckily we were not going fast when this happened. No warning lights came on. No codes came up on the computer either when checked.

Whenever I am driving my vehicle for an hour it starts to stall or sputter in traffic and the engine dies completely. It will restart but still continues to hesitate when accelerating. I've taken it to a mechanic and no error codes pop up when this happens so they do not know the cause or how to fix the issue.

2011 buick regal purchased from show room floor in 2011. Presentative maintenance up to date. No warning lights. Something terribly wrong with transmission, engine. While driving on city street approaching interstate at 25 MPH, car starting stalling, puttering, losing power. Pulled over, put in park. Then car would not go into gear. Would accelerate but would not go into gear or move. Had to be towed. First thing dealer service center suggest is $3000 transmission. Car only has 60,000 miles, one owner. No way! No prior symptoms or warning lights, in fact onstar diagnostics currently showing no issues found with engine/transmission system. This car is unsafe and should be recalled!!! 2011 buick regal diagnostics report from your 2011 buick regal as of 07/08/2019 no issues found

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.

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.
