When stepping on the brake my car jumps and stalls. Check engine light is on. This is 3 third time it has happened in not even a year.

While traveling at higher speeds (60+ mph), the check engine light will come on and the car will lose significant power in 4th and higher gear. This will present as speed can still be gained although very slowly in 4th gear, speed can be maintained but not gained while in 5th gear, and speed will only be lost while in 6th gear. 3rd gear and below all work fine. This issue is resolved by turning the car off for a while and then it continues to operate as it should thereafter, however, the check engine light will remain lit for a few days. The main concern is that the car loses the capability to get out of the way in the case of an emergency due to the lack of power while in this state.

Driving car locks up check engine light comes on says check power steering, we aimed to side of the shoulder car dies wouldn't start. We had to wait on side of a interstate for 3 hours to get a tow truck, very dangerous.

Our vehicle started losing pick up and go in the middle of driving about 2 weeks ago. Check engine light came on, so we took the vehicle to identify the issue. Error codes p0299 turbo/super charger underboost issue was identified. We called the dealership and were told the part is on backorder until maybe July. Even after market parts apparently are unavailable because gm is purchasing them. We contacted service manager at dealership because we are without a car that we are paying for and there is a huge concern that if the part is this difficult to obtain, there must be an undisclosed issue going on here. The service manager said they are only able to obtain updates for parts once the part is ordered, but also did confirm there is ( not necessarily a backorder, but the part is hard to come by!?!). He could not answer why. He did encourage us to contact consumer affairs to escalate our concerns. We did contact consumer affairs and were directed to contact NHTSA. We currently are without our vehicle that we continue to pay for and continue on this journey of tell this person or department and we are getting nowhere fast. Something bigger is obviously going on here and as always the paying customer continues to be the one paying for it. We want the part and it would be nice to not be inconvenienced with scrambling everyday on how to get to/from work and how to get to/ from caring for elderly parents who are in need of our assistance to eat, bath and remain safe. This issue is a huge inconvenience and truth needs to be told by gm/Buick.

Check engine light came on and then started flashing while in motion. The traction light came on and off repeatedly. The engine had reduced power and at times would only go 30-35mph even with pedal mashed all the way. I took the vehicle to o�reilly's and they checked the codes which show camshaft sensor, crankshaft sensor, cylinder 2 misfire, turbo underboost code and abs code. Seems like a lot of issues for a vehicle with only 67,000 miles.

Early this year we start having problems with the check engine light coming on then the reduce power to engine coming on, so we took it back to the dealership we bought if from. So first we had to have three sensors changed, we did that and after that was done it still kept jumping on 4 time before it stopped. Then June of this year it started back we took it back to the dealership then they tell us we need a new catalytic converter, have that replaced again it keeps doing 3 more times then it stops. Well we figure we have the problem solved, but no on 10/26/2016 as my sister is getting on highway 57 in chicago the check engine light comes on and the reduce power to engine comes on, so now she is pulled over on the entrance ramp trying to get this car to act right, finally after she had to keep starting it up and shutting it off she gets it act right , but the check engine light is still on, after she left the event she was at the check engine light was off. Now on 11/04/2018 I'm on the dan ryan expressway in chicago one of our most busiest and dangerous highways it does it again, the check engine light comes on and the reduce power to the engine activates, so now I'm pulled over praying I don't get hit by a truck, I get it to act right finally and I get off just encase it do it again, I make it to my destination and when I get ready to leave the check engine light is off. On 11/05/2018 I'm only 5 blocks from home and it does it again,I get it to act right after I have to keep starting it up and shutting it off and low and behold I get 10 blocks and it does it again get it to act right make it back home check engine light still on when I get to the dealership then turn it off and then back on and the check engine light is off. This is beginning to be a big problem cause it's going to cause a accident when it does that, and the dealership can't find the problem.

Still having problems with the throttle body took it to the dealership on 2/9/2018 paid out $545. 00 to have purge solenoid and evap flow changed and to have the throttle body cleaned and adjusted. Well 4 1/2 hours later the check engine light comes back on and it starts with this reduce power to the engine again. The reduce power to the engine did this 3 times and each time I had to shut the car off wait 30 seconds and restart the car and each time it did this I had to restart the car 4 time before it would go off and the car was able to be driven. The check engine light stayed on for 4 hours before it went off, well that didn't last long before I start having the same problem again on 2/11/2018 letting the car warm up the reduce power to the engine came on and I was still in the garage, that was 7:30 am then again at 8:05 then again at 8:37 so now again the check engine light is on. I want get on the expressway cause of this for I might get killed or injured, gm really needs to do something about this and someone needs to make them repair this problem.

Lately I'm having a issue with this car, first my check engine light came on and is still on and now all of a sudden I can be at a light or driving down the street and the engine power reduce warning comes across my display screen, I can't accelerate so I have to coast it to the side of the road, shut it off, wait 30 seconds and restart the car. Sometimes I have to do this 2 or 3 times before it drives right again, so I went on the Buick forum and see a lot of people are having the same issue, that they have had the throttle body changed and it makes no different, that it could happen again. So now I want get on the expressway just in case it wants to do it again, and I'm getting scared to drive it on the streets cause it keeps happening. Some say cause it's cold where the live but I feel it shouldn't be happening all, like on 1/8/2018 it happened this morning and the temperature outside is 35 f and that's above freezing. What can be done about this cause gm is not reporting it to the NHTSA, so if you don't go on there forum you don't know. . . . . Help scared to drive my car.

I was driving on a highway at 65mph. On a straight portion of the road the engine light came on , the engine revved up to over 4000 rpm, the power steering locked up, and many other lights came on on the dashboard display. This was a very dangerous situation trying to control the car. I was forced to slow down and when I reached 40mph the power steering came back on. The engine was still running over 4000 rpm. Most of the dashboard display lights went off except for the check engine light. Had to drive under 40 mph until I got home. While this was happening my onstar sent me a notification that there was something wrong with my transmission. The car was then towed to the gm dealer. At the gm dealer they could find nothing wrong. There were no error codes in the cars computer.

Car ran great then I stopped at a stop light. When it turned green the traction control and check engine light came on. Engine power reduced came across dash and the car failed to accelerate, the car, radio and lights were still on. Almost caused 3 different accidents trying to get out of traffic. Scan check system, p2101, per document id:[xxx] diagnosis was to replace throttle body and perform jdle relearn procedure. Information redacted pursuant to the freedom of information act (foia), 5 u.
