general problems of the 2011 Buick Regal

While driving on the highway at 60 mph, warning on dash came on saying “engine power reduced” and drop down speed to around 25 mph and I could not accelerate more than 25 mph on the highway which could have caused an accident because of the traffic flow behind me. I put a code scanner under the dash and it read code p2138, throttle pedal position sensor switch.

Preparing to park into a parking space in an off street parking lot the vehicle forcefully and rapidly accelerated on its' own and crashed into a fence. I was not accelerating. I attempted to stop the car using the brakes but they did not engage quickly enough to stop the rapid, forceful, and without warning acceleration. Buick has been contacted about the defect. Buick ran extensive diagnostics on the car and denies there is a defect. Police came to the scene and advised that given the 2 other incidents that I have experienced, the car is unsafe to drive given potential damage to others. A police report was filed.

When pulling into parking space the car rapidly accelerated on its' own and crashed into the car in the next parking space. I did not have my foot on the gas, the car was simply idling. The acceleration was so rapid that applying the brake was useless.

When I shift the car from park to drive it does a very hard jerk. And vehicle has no codes on dash or anything.

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.

Our cur completely shut off all power lights engine everything doing 80 mph on interstate 84 in idaho. A semi seen it happen jumped in the middle of both lanes to block traffic so we could get to the shoulder. In a no cell phone area 13� we disconnected the battery and had to shift srive it in limp mode. No alert lights came on we took it yo a certified dealer to find the pistons, timing chain and other things are ntoken gm/ Buick was notified they decided to decline assistance because we are out of warranty 93k miles on the car and over 5,000$ in repair and possibly another 2100$ to repair the cadilitic converter. We were in a no cell service area and had to drive in the shoulder now the headlights won't turn on at all either. The car never alert us it just shut off the dealer says the oil was very low again no oil light came on with that yhe dealer says therecould be a bcm/ecm communication issue costing 1200. 00 to 2500. 00 to fix. They can't assess completely until the piston/ timing belt issue is fixed but the car is not communicating the steering is now super tight and the only yhing it says now is service stibilatrac and the mechanic didn't even bring that up.

Icar only has approx 86,000 miles. Was riding down street car shut off. It turned right back on but it was making a very loud noise. Parked it. Next morning went to start it and it wouldn't. Had timing silenoids and starter changed. Car is read no codes and it still went start. Had taken to another shop for second opinion. They said I needed a motor. Where am I to get $2800.

I was sitting in my brothers yard with my car crunk up and when I began to put it in reverse it started making a strange noise. So when I put it back in park the noise stopped. So I put the car back in reverse so I could back out his driveway, but this time the car wound not move. So I put it in drive to see would it go forward and it did for maybe a hundred feet but it would not switch out of second gear.

None of the 4 recalls were fixed on this 2011 Buick Regal cxl 2. 4l car when I purchased this car at billion auto in iowa city, iowa. The stabilitrak is bad and was never brought up in the process of purchasing the car and I have had to change my brakes, rotors, and calipers in the rear both sides 3 times in the last 2 years. I'm not happy.

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.

While merging onto a busy highway, the transmission would not shift into 3rd gear. It lost power and almost caused an accident. There was no previous warning of a transmission problem. The traffic was heavy because of the holiday weekend. With little room to merge, I attempted to speed up with traffic when it failed. I was forced to pull over and limp along the side of the road in second gear until the next exit with cars flying by at 70-80 mph. This was caused by the "wave plate" in the transmission coming apart according to the transmission shop. They also said this is a very common problem with these transmissions. Buick knows about this problem as listed in 2007-2009 recalls but does not do anything for 2011 models. There is also a pia bulletin pi0780a for this exact same problem and model year. Gm refused to take responsibility for it. There are several forums with the same problem. It it going to get someone killed.

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.

My vehicle issue is that the exhaust valves were bent due to a valve cover bolt that released and damaged head valves and head on motor. This is a factory issue due to the bolt releasing. I am being held responsible for vehicle and only owned vehicle for less then 2 years. For replacement head cost and or replacing the motor itself is a costly situation. My vehicle was parked in city limits and when attempting to start,would try to turn over but just keep spinning without full crank. I shouldn't be replacing the motor on vehicle that is still well under 100,000 miles and no major issue prior.

Check engine light illuminated at 82000 miles. Using the scan tool from a local auto parts store, I observed that the obd-ii codes were p0016 and p0017. Around the time that the check engine light came on, I noticed that the shifting done by the automatic transmission seemed jerky, and that the engine was noisier than usual even when idling. Generally the miles on this car accumulate from equal time spent on both city and highway conditions. The engine rough idle and choppy gear shifting were apparent during both types of conditions. The check engine light remained lit for five days before I took it to the dealership for diagnosis. Dealership diagnosis said "jumped timing chain front guide came apart p0011 p0014 p0016 p0017 set in system. " the dealership replaced the timing chain using a time chain kit, replaced the intake and exhaust actuators, and replaced the oil and filter. Three days have passed since the repair was made, and the engine seems to be operating normally.

I was parking in marked space. I had turned into space, my foot was off the gas pedal. The car was 3/4 into the space when it malfunctioned and rapidly accelerated into a hardened snow bank. I instantly braked but there was not enough space to avoid collision.

Timing chain and water pump chain and all the other good things that go along with this needed to be replace on my 2011 Buick Regal 2. 4l engine just under 25000 milesthis should not have happened at this mileage. What if this decided to go while I was on the highway. . This seems like a problem that needs to be investigated.
