During the past 3 years I have had to replace the battery 3 times, my daytime running lamps keep turning off, I have had to replace the ignition coil and now my car has been at the dealership for a week because there is an electrical problem they cannot figure out. The chassis control module was replaced but did not fix the problem. My personal mechanic advised the TCM was coding, but dealership said no. I am beyond frustrated! These problems started around 60000 miles and now it has 83000 miles on it and can't be driven. If GM knew about the issues (as found in multiple articles on line) why didn't they disclose?

I was driving on a 70mph highway. Went to pass slower vehicle. The car did not react to the accelerator. In fact it slowed down with the engine trying to rev up. Luckily, there were no other vehicles trying to pass at the same time because I had to drop back. Car is currently at a Buick dealership for engine propulsion repair. Do not have complete estimate for repair yet. Was told could be approx $2300. One year earlier, at 50000 miles had similar acceleration problems because of catalyst converter. The catalyst converter was replaced under warranty.

If the vehicle detects a turbo under boost condition, engine power is immediately reduced (limp mode) with no indicator light or warning to the driver. This happened on a mountain highway, I did not know the vehicle was in limp mode and as I accelerated into traffic I was almost hit by a truck from behind. I learned through experience, if no turbo boost error occurs during the next drive cycle, (ie coming home down the mountain road) the pending code is cleared and the same condition can happen again, again without setting a cel.

Battery West even a year old and it went out. Dead. Coolant was leaking. But wasn't leaking at first. I believe they damaged it. When we took it for check up the same warranty was going out and they said we will make sure everything is working. They just half fix every thing and got the money. This is a lemon.coolant leak and conditioning still don't work.what do you do.just

On 5/26/18 I test drove a used 2014 Buick Encore at gulf coast Chevrolet Buick in angleton tx. I liked the car but noticed it idled a little. I spoke with the sales associate and the service tech and they both said that was normal for the car. I decided to proceed and purchase the vehicle. Since then I have had multiple issues with the car, including the rough idle getting worse. Since May 26 2018 my car has been back at the dealership for repairs 4 times. Each of those times I requested for the rough idle to be looked further into along with the other issues it was having. This last time I took it in on 07/30/18 due to a service light coming on battery saver active, I told them for a second time there was still a chirping noise under the hood and told them again it has a rough idle that seems worse. That while in park and while sitting at a stop light or stop sign with my foot on the break its rough/shakey feeling. And when sitting at stop lights it also will sputter while sitting there in gear. They told me, they could not duplicate service code and they didn't even see it, they could not duplicate the sputtering, but it did need a new camshaft seal. That the blown seal was causing it to chirp and repairing it probably fixed the rough idle. It did not fix the rough idle! I spoke with service manager and the general manager on 08/07/18 after service called on 8/5/18 saying they couldn't duplicate all the issues I explained. Service manger said they could not get it to duplicate the rough idle and sputtering. The general manager test drop my car and then gave my key back saying your car is ready it runs fine. As I go to leave the dealership it does the issue again. I drive it over to service to get them to sit in it and feel what I'm talking about. He does and says he feels it, but its probably just the ac and hands me the key back.
