pack and spark plug needed to be replaced. The vehicle was taken to an independent mechanic, where all the coil packs and sparks plugs were replaced; however, the failure recurred several days later. The vehicle was taken back to the independent mechanic, where it was determined that the failure was related to TSB Number: 16-NA-383 (Engine and Engine Cooling). The dealer was contacted and informed the contact that the TSB was VIN specific, and the vehicle was not covered. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 85,900.
We purchased this vehicle in May 2016 and from the beginning had strange issues with the engine. It was in and out of the dealer with them trying to figure out the exact problem. They could not, so they contacted GM for approval for an engine replacement. We were concerned about going this route but were assured it would be taken care of for the life of the car. After the replacement in July 2016, the car seemed to be better but other weird issues arose. The engine always made a squealing noise that we were...

told was fine. We have done all required maintenance, recalls, and regular service. For the past 2 months, the car has had strange shifting issues. It was taken in to be looked at and nothing was found. The transmission received its' routine maintenance on schedule. It still was a problem and we were told to drive it until a code appeared. The car got progressively worse and had great difficulty shifting, which had us involved in a few close calls. Took it to a different dealer that also didn't find a problem. They said since there was no code, but seemed transmission related, they would drain it and replace the fluid. This also didn't work. We continued to drive the car and almost ended up stranded in the middle of the night while driving the freeway. The car became almost uncontrollable. We made it home. But, the following day while driving it to work, the car was jerking, stalled, and then lost the capability of reverse and neutral. We had to have it towed and a new transmission put in. We were told by the dealer that there was an explosion in the transmission, and we were lucky we were somewhere safe when the car died. It's very frustrating paying for a vehicle that didn't seem right from the beginning. We have put well over $6,500 in trying to repair a car that seems like it was never right in the first place. We have been fortunate that neither of us, or any of our children, have been hurt considering the major issues with our car.
Engine has a defect that causes a piece of the engine to break off and end up in the oil lines, ends up in oil pan. This defect causes the engine to freeze and owner must replace the engine. My vehicle only had 50k miles and I am unable to drive it. I now need a brand new engine and buick knows about defect but won't issue recall or fix the defect. I was driving on highway when engine shut down
When accelerating the vehicle after coming to a stop or slowing down stumbling/stuttering occurred along with the check engine light coming on and the stabilitrak/ traction control light. Continued on into the next day with the same problems except the check engine light turned off and came back on with an oil light. Waiting on dealership to inspect. Dealership mentioned multiple cars there with the same problem.
I was entering a city street from a shopping mall. As I found a small break in the traffic I pulled out and attempted to accelerate. My car did not change gears. I was forced to pull off the road quickly to prevent my car from getting hit from the rear. I had been driving around all day on the interstate and various shopping centers without any indication something was wrong with my car. I had it towed to the dealership. This is the 2nd transmission problem with this car in 4 months with now with only 27k miles. It has been in the shop for 25 days now and not sure when it will be ready this time.
