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

I was driving down the highway in texas, and was in the process of changing lanes to the left and accelerating when all of a sudden my vehicle completely lost power and would not go into gear. My transmission light immediately came on. The psl was 70 and thankfully I was able to move back into the right lane and navigate to the shoulder without getting hit. I eventually coasted off the hwy and had aaa tow my car to the dealership where it was determined my transmission needing rebuilding. This occurred around 30k miles. Periodically after that my car would not accelerate like I had a misfire and I'd feel a shudder or sometimes it felt my tires were spinning faster than my transmission was going. I took my car in for an oil change (no lights were on). I explained this to the dealership and my car was throwing a code turns out the torque converter needing replacing. This was under 50k miles. I am currently at 52k miles and when I go up a high I feel the same thing and have told the dealership this. They won't give me a loaner car and I can't be without my car so I have not currently brought it back in. There are no lights on but it feels like the same issue is starting back when the torque converter went out. I have always had my car serviced at the dealership so I have all the records.

Vehicle had 45000 mile's when I bought it in oct 2017 and now has 47500 miles. Car had no problems and drove and looks like new. Last week (09/07/18) it started bucking going down road at @30mph, then would jump into gears at stop. Then did not want to go into reverse. Would not shift out in forward gears. Manual would not work either. We were stuck in traffic at busy intersection...all in about 10 minutes time. Limped to aamco transmissions and left it...diagnosis was needed to rebuild transmission..cost;3400.00 have read this has happened on other 2011 models. Should have been a recall..45000 miles is still like new and this should have and could have been avoided..I was lucky to have not been in an accident. Was just driving normal in city when happened.

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.

I was driving the car at 40mph when all of a sudden it cut off and all the gauge lights came on. I was nearly side swiped by another car. I restarted the car but it would not start. I tried to start it up again. It started but would not shift out of park. The gauge lights on the dash board were still on. I restarted the car again and was able to drive it home; the signal lights and head lights did not work. When I was finally able to start it up and take it to a mechanic, I was told the problem was the ignition switch. I paid a total of $540 for them to repair this problem. Gmc knew about the problem and did not report a recall to consumers nor offer to fix it. All I'm asking is for a refund of the money I paid; $540.
