The morning of dec 8 I was pulling into my job parking lot and the engine shut off 3 times. After work on the way home I noted a rough idle. I pulled into a gas station and it shut off again. I was about 100 yards from my gm dealership so I parked it there for service/repair the next day. I was called on the 10th and was told it was the timing chain and this repair would cost approx. $2200. I was then told on the 12th that the timing sprocket and cam shaft would have to be replaced adding cost to this poor material or poor workmanship. I remember a recall on a engine earlier in the year that I thought the dealership repaired which I believe was something involved with the cam shaft but I know they had to go into the engine. This shutting off while the vehicle is in operation really scared me and the cam shaft, cam shaft sprocket and timing chain should have been made of a better material, a stronger material. $2000 spent earlier plus the $2200 estimated no I could have purchased an engine for $4200. My vehicle is currently at burns chevrolet being repaired since dec 8th. This is a real safety issue that should be looked into.

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 driving down the highway with my grandchildren. I was going 50 miles an hour and all of a sudden no warning the car like stalled and reduced engine power light came on . Car stalled and I started it but wouldn't let me go anywhere! It was dangerous and could have gotten us killed! I called gm to report it for a safety recall. I had to pay $120 for a tow. Took to buick dealer it was a screw that wasn't torque right on the timing chain. I had to pay $500 . I shouldn't had to pay anything. Now I no longer have the confidence in the name or my car. It runs rough and it starts terrible shaky. Only 50,000 miles on it. Can you imagine being on a highway and your car stalls. Thank god no one was behind me. I have receipts from tow company and the buick dealer but they would not give me the papers to my vehicle. That had exactly what they did. So on my receipt it says miscellaneous! They refused to give me anything else. My car has 54,000 some miles. My warranty expired in february 2016 only had the car a little over a year. For some reason I could not put the mileage below.

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.

Engine keeps stalling., it happens at intersections and randomlly after accelerating. The car dies. I have had this checked by dealers and several mechanics. Very loud noise when vehicle starts up. Runs rough and does not accelerate correctly. Shakes whenever idle and turns off randomlly. Possible ECM software update needed based on internet search for the similiar issue with this model and year. Dealer was unable to assist or even comment on any updates to software without going in and paying for inspection again. Fuses, air intake, o2 sensors filers, everything has been checked.
