2 Vehicle Speed Control problem of the 2022 Buick Encore

Failure Date: 07/04/2025

I have had my vehicle to a gm dealer on a few occasions with the emc code stored in the vehicle and an active check engine light on. While I’m driving - now during 70 percent or more of my trips - my vehicle loses power very suddenly and lunges me forward. I’m unable to stop and go on hills of any noticeable grade and have narrowly missed being in an accident many times. The dealer’s service manager has told me I should just bf glad the car is drivable when I have expressed ongoing safety concerns. I cannot get assistance from gm nor from the dealer in having this warranty connected part replaced. I do not have any other vehicle to drive, and I know I’m unsafe. I teach school and must get back and forth to work.

3 Vehicle Speed Control problem of the 2018 Buick Encore

Failure Date: 05/05/2025

While driving, my car began to glitch out. The screens started turning on and off, the doors began locking and unlocking, and I lost my ability to steer, brake, and accelerate. It caused me to run a red light and I almost got into a severe accident. This issue has occurred several times, and during more recent occasions the car has turned off completely while driving. There were no warning lights or messages indicating that something was wrong with the car, but sometimes when I turn the car back on, it says “calibrating. ” if Buick has sold cars that are capable of losing complete control, this should be investigated immediately.

7 Vehicle Speed Control problem of the 2019 Buick Encore

Failure Date: 02/06/2024

My radar to let me know I was going to hit something didn't go offer. It has never failed before and has been overactive actually which I appreciated before. I was doing 60 with my paraplegic wife (luckily not our 5 year old as well though) in the right lane because it's safer to go slower and be there. I was distracted by a strange machine being transported on a truck to my left. This was my fault. I hear the ultimate responsibility and the majority if not all of it. I saw the road construction trucks 400 feet ahead of me at most. Maybe less than 300 and luckily no one was to my right the truck distracting me was ahead so I had room to avoid hitting the construction truck with the sign saying move over. It was doing maybe 15. I almost killed my wife. It was my fault but still the $3000 safety package failed. Almost catastrophically.

Failure Date: 04/07/2020

I had purchased a 2015 Buick Encore vehicle on March 03, 2020, that had a "not for sale" yellow sticker on the windshield. I had notice that the vehicle made a thumping sound under the hood on the driver side when riding on the highway. I took it to johnny londoff service dept. , but was told that nothing was wrong with it. In addition, to noticing that the vehicle would roll backwards on the smallest of incline. As time went on the vehicle would roll back, then roll forward on leveled grounds when I would take my foot off of the brake pedal. I took the vehicle back to johnny londoff service dept. , and again was told that nothing was wrong with the vehicle. I took it to telle tires and auto center and found that the suspension was worn out on the front and back of the vehicle, with struts and spark plugs needed. This vehicle rolls back when sitting at a traffic light, at, in line at a fast food drive through, and just everyday driving. Johnny londoff should have fixed the damages and/or repairs needed before selling me the vehicle. I would not recommend buying a vehicle or doing business with them.

Failure Date: 11/05/2019

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 car had been parked in an unheated garage for more than 24 hours. I started it, put my foot on the brake pedal, and put it in gear (r). The car lunged back at a high rate of speed. My foot was still on the brake. To avoid hitting a vehicle behind it in the driveway, I shifted to drive (d) and the car immediately started forward still at a high rate of speed. The brakes did not slow the car down. I bumped the front wall of the garage and again shifted into r. The car started moving back again and the brakes did not work. I turned the engine off and the car began slowing and came to a stop after bumping the vehicle about 20 feet behind it. My foot was on the brake pedal the whole time. I checked for obstructions around the brake pedal and found none. Afterward, when I started the car again, it drove normally without trouble. There was no apparent damage to the car as a result of either collision but the garage wall suffered some minor damage.

24 Vehicle Speed Control problem of the 2013 Buick Encore

Failure Date: 01/28/2013

Leaving a stop sign onto three lane road going down a hill,when the car had no acceleration, I put on flashers and coasted to curb,had to call wrecker and be towed to dealer,said it was a throttle body sensor,that is sensitive to cold weather,2 dealers said the same thing. New part was ordered,but I don't feel safe in our cold weather if this happens on highway and it stops I am so afraid I will be run over by traffic moving at the speed limit and my Encore just stops. Feel my new part is not the fix for this safety issue, they say they can't say it won't happen again. Also read someone in n. D. Was having same issue. Hope you can look into this.
