NHTSA complaint #11747114 — an unverified report by a vehicle owner.
I am reporting a serious safety issue with my 2023 Buick Encore GX that repeatedly shuts off while driving and doesn’t restart when auto stop is on, it leaves me stranded in traffic. The vehicle has been in the shop multiple times since February 13, and the issue has not been resolved. A service advisor has stated he is not comfortable putting me back in the vehicle and wants to help get me out of this car. I am requesting escalation, a case number, and immediate resolution. After having the oil changed in February, the check engine light came on soon after. Car had left me stranded prior to the battery being replaced. After 4 times in the same shop, they say a bad ground connection may now be the problem, however they also said they recharged the battery the visit prior.

Brake System Control Module Replacement - The brake system control module needs replacement due to a fault detected with 10 volts on terminal 1. Replacing this component can help maintain proper functionality of the brake system and ensure consistent performance. Why would this all of a sudden be faulty after almost 5 years?
NHTSA complaint #11708527 — an unverified report by a vehicle owner.
The brakes squeak constantly and occasionally skid or lock up. The car will occasionally have all electrical power disconnected so all screens go blank for 2-3 secs (sometimes in succession for 3 times max), the car will continue to run and drive. However, the screens will blink as if starting up each time the car does this. The car will also indicate 44 miles left until tank is empty, working 10-12 more miles the car will stop as if it’s out of gas and will not start again until you put gas it (all indications on gauges show enough gas to go 25-30 miles left). Very disappointed in the car and dealership can’t figure it out.

NHTSA complaint #11656817 — an unverified report by a vehicle owner.
I was at a stop light and the light turned green, I preceded to press the accelerator, I was just starting to move forward and the, peddle seemed to take over with my assistance went all the way down and began speeding up. I tried breaking and the car just kept going and not wanting to slow down and kept gaining speed, I had to put car in neutral and turn engine off. Same day, same trip about 4 miles down the road, I began to slow down (35mph) due to a turning vehicle and when I was clear to accelerate once again, it happened again, again, I tried the breaks, and the car kept fighting the break and kept gaining speed, once again I had to put the car in neutral and turn off the engine, the speeds reached 65 mph. before I was able to place in neutral and turn off the engine. No warning lights, car ran normally until those terrifying moments, no check engine lights on before or after the above experiences. My husband and I's safety was put at risk due to the road's travelers and Deadmans curves and cross sections, it put us at risk with a higher chance of crashing into a vehicle or accelerating before being able to make a turn safely. As soon as I made it home, I called the Buick service center and delivered the car the following morning to the service technician. It is at the Ross Downing Service Station today.

This is a new issue. Upon exiting my car last night. My car would not shift into park. Everytime I cycled the engine and shift to different gears then park. The car stated it need to be shifted into park still. Without it being in park The car could possibly roll down the hill. Also without it being able to be shifted into park. It continued to flash and keep lights and warning sign on. If not being able to shift into park. I could not leave my car until it recognized the car was in park. The car battery would have drained.

The contact owns a 2021 Buick Encore GX. The contact stated while driving at approximately 35 MPH, the brake pedal was lightly depressed and the vehicle unintentionally came to an instant stop; the vehicle then began to shudder. The contact's mom was seated in the front passenger side of the vehicle and sustained a neck injury after the failure occurred. There was no one injured that was not in the vehicle. No medical attention was required. The vehicle was drivable and was driven to a dealer who did not provide a diagnosis but informed the contact that, the failure may have been occurring due to the Vacuum Module in the braking system needing to be replaced. The vehicle was repaired; however, the failure still occurred. The manufacturer was made aware of the failure. The failure mileage was approximately 2,500.
NHTSA complaint #11610192 — an unverified report by a vehicle owner.
Brakes squeaking, squealing and screeching. Replaced once at approximately 8k miles. Dealership ground down rotors twice, brakes replaced once. Tires are worn in the center. AWD GX, steering seems off and unstable. Brake pedal sounds and feels like a faulty spring inside. Pedal gets stuck when switching from gas to brake. Bounces back with spring feel and noise. At times it feels like I can’t control the brake when traveling at a low rated of speed and having to suddenly stop. Then while stopped on an incline the brake feels as if it releases while still depressing the brake jolting forward. Nearly forcing into intersection. Having to leave larger distances between vehicles in front to prevent vehicle from forcibly trying to rear end another vehicle. Clunking noise when turning left at a low rate of speed with minimal acceleration, such as in and out of a driveway, parking lot or after coming to a stop at an intersection. Mostly heard only turn left. Steering wheel vibrates at high rate of speed. Intermittent rattling noise heard from front center/passenger side. Ratting noise occurs after driving a while 25-30 minutes. Screw fell out of vehicle after being serviced at a local dealership, took it back with said bolt and they did not put it back. To date I’m unaware of where it belongs. Dealership has oil change tech diagnosing, consistently “functioning as normal” and “can’t duplicate issue”. I do not feel safe driving. Hard to stop and feel in control. I’ve resulted in getting rides from others when possible. 2023 GX AWD is not safe. Manufacture notified.

While driving at a low rate of speed, turning or speed bumps the vehicle starts to rattle in the front end and steering wheel. Engine feels like it slips while rattling from the front. Seems like a motor mount, suspension, tie rod or some other component. Brakes are very hard and make lots of noise. When starting the vehicle on an incline it Lunsford forward out of control.

I was driving and randomly my new 2023 Buick Encore GX and two error messages popped up and my brakes started being less responsive. The two error messages that popped up was "Service ESC" and "Service Power Steering". I will be calling the service department tomorrow to get it checked to make sure nothing is wrong. This is apparently an issue with GM cars but I need to verify that it is not an ongoing issue.
NHTSA complaint #11524332 — an unverified report by a vehicle owner.
Our new 2023 Buick ENCORE GX's brakes continually GRAB whether we are approaching a slowed vehicle in front of us or not. Also, beginning yesterday, the brake pedal that I step on to start the vehicle was totally locked up and I was unable to start the car for awhile. Then, this issue went away and I could start the vehicle. More so, the constant grabbing of the brakes is dangerous. There is no rhyme or reason with this dangerous problem. The Buick dealer in Redlands says they are aware of the touchy brakes but offer no resolve. Can you help us? Thanks
