Since 2016 my vehicle collision alert has been inoperable and giving false alerts.. on numerous occasions, I had vehicles ignore the yield sign at high rate of speed cutting in from on my vehicle nearly causing an accident. The collision alert never went off until 45 minutes to an hour later...my vehicle has been taken to the kent county motor Buick dealership in dover, de where it was purchased for service. Numerous times they could not pinpoint the issue. GM engineer was notified by the dealership to ascertain assistance and I was informed by the service dept. That it may recognize an alert and it may not recognize an alert. For the last 3 years I've been dealing with this issue. In Jan of 2019, I personally contacted GM to complain about the ongoing issue. They gave me a case#9-4980258634 and to return the vehicle to the dealership. The dealership upgraded the softer ware and attempted to duplicate the issue but to no avail. The collision alert failed. GM senior advisor paige called me indicating "the vehicle was designed to do what is suppose to do" and the vehicle was safe. I questioned Ms. Paige and asked her how can my vehicle be safe when the vehicle collision alert is not functionally like it suppose to. All she can say is vehicle is designed to do what it's suppose to do. I informed Ms. Paige that was unacceptable and GM needs to alert consumer of the faulty collision alert. She continued saying GM can not do anything for me because "it is designed to do what is was suppose to do".

On September 1, 2016, I leased a new 2016 Buick Envision, solely to get updated safety technology that was not on my 6-year old Buick regal. I had seen the Envision at car shows, had picked up sales literature there and at local dealership, plus received online information. This vehicle was advertised as having front end collision alert with automatic braking. In April 2017, I received a letter from Buick/GM that my vehicle doesn't have the auto braking and there had been an error in their sales products. I immediately wrote to them. A couple months later I received a call offering me 1 year of onstar, 1 year extension of warranty, or $1500 accessories certificate. I explained that I don't use onstar, the existing warranty runs the length of my lease, and that there is no need for $1500 accessories on a fully-loaded $48000 car. So I wrote another letter, to which there was no response until I filed a claim with the Ohio attorney general's office. Again I was offered the same 3 selections for my "inconvenience". this isn't an inconvenience. It could be a life and death situation. The front end braking was the main reason for purchasing this vehicle. It seems false advertising requires more than a letter.

When I push the push-start button, the vehicle makes a grunting noise, but it does not start. All the lights come on and stay on including the "check engine light." It has happened four times. It happened three times when the vehicle was parked in the garage, and once when the vehicle was at a parking lot. The vehicle has been towed twice to a dealer; however, after the vehicle is thoroughly checked, they don't find anything wrong with it. Apparently, there is no trace of the problem in the memory of the vehicle. On 5 October, I was ready to go to work, but the vehicle did not start. This was the first time that the vehicle was towed to the dealer, the service manager tried to start the vehicle but it would not start. The vehicle spend the night at this dealer, but when the mechanic looked at it the following day, it started right away and they could not find anything wrong with the vehicle. The mileage on the vehicle was 4357. On 20 November 2017, I drove to work, and after a couple of hours, I needed to run an errand, but the vehicle would not start. Once again, the vehicle was towed to the closer dealer. We arrived at about 5 minutes before they closed. The following day, the mechanic took a look at the vehicle, but he could not find anything wrong with it. The mileage on the vehicle was 5359. GM did call this dealer and offer some type of support to replicate the problem; however, the problem could not be replicated. Since it has been four times that the vehicle has left me stranded, I don't feel safe. I do not have pictures, but I do have small video clips of the last two incidents.
