2022 Buick Envision Engine Problems

Purchased 2022 Buick Envision on October 15, 2022, currently has estimated 2400 miles. One month after purchase at 2200 miles, November 16th, a squeaking noise started coming from engine when you turn the vehicle off. Additionally, engine makes a whistling sound when accelerating/ changing gears. Took vehicle into service station, showed service tech the recorded incidents on video, it was indicated it was the turbo hose causing the engine noise. Buick Morrow, GA service station kept vehicle for two weeks - indicating time needed to order hose/replace the turbo hose. Picked vehicle back up on Monday, December 5, 2022, the squeaking sound returned - recorded incidents. Vehicle engine continue to whistle when accelerating. I am scheduled to return my vehicle back to the Buick Morrow, GA service station today, December 9th to have the same reported issue looked at again.. Note: Filed a complaint with corporate and have requested the issue be escalated due to my concerns with the vehicle safety.

This is my 2nd complaint regarding this car. On, 11/5/22, I was making a left hand turn on a highway, and heard a humming sound, that was elevating like the sound of an airplane. At first I thought it was coming from the music that was playing. I turned it down and the noise was still there. The screen then went black and had red writing on it. I have to have one set of gasses to drive and another pair to see up close. My GPS talks thru the screen and started talking, because I was turning, and I was unable to change glasses quickly enough to see what it said. I did report it to one of the owners of the dealership at the time, but received no answer back. when I went to have the oil changed recently and have the heated seat modules installed, I asked them to pull up the codes, to see if it would show what happened. The service guy told me that when that happened it was because the car had lost communication with the computer. He gave me a copy of the codes list, but I'm not sure if it is a complete list or not

On 10/12/22 I was stopped at a red light. I was the first person in line at the red light, right at the entrance to the NYS Thruway. When the light turned green, my car locked up and I was unable to proceed. People were honking at me but the car would not go out of park. Some road construction workers ran over to the car to see if they could push it out of traffic. I kept trying to turn it off and restart it. Finally, after many attempts it finally went into drive. The light was now red again, but the construction workers, held up oncoming traffic and told me to just go. I was on the same road as the the dealership where I leased it, so I called them, told them what happened and that I was on my way there. I had also received a message from Buick at the same time, saying it detected an engine/transmission problem with my car. The dealership told me not to bring it in, but I took it there anyway. I had lost my husband a month earlier, so I had no one to call at home to come get me. They kept it for a week, and said they couldn't find anything wrong, so had me pick the car up. They also said that someone had been driving it everyday, checking it, but you can see from the incident report, that they drove it a total of 3 miles. also, on the report that they put that I had said the check engine light was on. That is not true. I never told them that.

My vehicle still has a delay or hesitation with the shifting of gears while driving, causing a loss of power. At random times the vehicle has lost power while driving. Additionally, when the vehicle is turned off, there is a loud noise (knocking) coming from the front of the vehicle. Also, while driving there has been a burning smell. The vehicle is again scheduled for repair of the persistent issues that GM-certified specialists say the issues could not be duplicated. Recently the infotainment center blacked out after being the software updated. The screen produced issues with a variation of colors which disabled the use of the infotainment for several hours with the screen frozen. This is my second report of the same concerns with the same vehicle reported on 2/22/2022 as this vehicle is only six months young. The vehicle was inspected by GM's branding inspector in April of 2022. GM informed me that they did not find any issues at that time, but offered a settlement of repairs of 50,000 rewards points unbeknownst to me. As of June, GM offered another settlement offer of repairs only. However, GM has stated there are no issues. A lemon law warranty claim will be submitted.

What component or system failure or malfunction, and is it available for inspection upon request? AUTO STOP/START-POSSIBLE TRANSMISSION How was your safety or the safety of others put at risk?- The issue is the AutoStop feature and the transmission. When driving, it appears that the gears are not shifting correctly; also, while driving, the RPM has reached a high level of 5 multiple times, which is now a cause for concern. My minor son and I were driving today, and an 18 wheeler started veering into our lane. When I sped up to move over to the next lane, the vehicle hesitated, the engine revved up, and the vehicle started moving slowly. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle is en route to the dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO ? The issue is the AutoStop feature and the transmission.
