BUICK Complaints

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?

I am writing to report a serious and ongoing safety issue with my vehicle. While I was actively driving in traffic, my car suddenly shut off completely without warning. This occurred while the vehicle was in motion, creating an immediate and dangerous situation. During this incident, the steering wheel locked up multiple times while I was driving, making it extremely difficult to control the vehicle and safely maneuver through traffic. This put not only my safety at risk, but also the safety of other drivers on the road. In addition to this, there are multiple mechanical and safety-related issues with the vehicle: •The driver’s seat is stuck and cannot be adjusted. •The front doors will not lock. •The back doors will not unlock. These issues significantly increase the risk of injury or harm in the event of an emergency, accident, or even while the vehicle is parked. Given that the vehicle shut off in traffic and experienced steering lock while driving, I do not feel the car is safe to operate. I am requesting that this matter be reviewed urgently, as this vehicle presents a serious safety hazard to myself and others. Please advise on the next steps for inspection, coverage, or resolution as soon as possible. Thank you for your prompt attention to this matter

When I start at a low speed it's like it does not know which gear to go in. You push on the gas and it does not move much and then launches forward. It has done this since I purchased it in April 2025 used.When in auto stop and the engine starts up with my foot still on the brake, sometimes it will lurch and buck. Buick dealer did do a transmission fluid flush and it still does the same thing daily.

The contact owns a 2019 Buick Encore. The contact stated that after the vehicle was stopped, the gear shift lever was stuck in park(P). After several attempts, the contact was able to move the gear shifter lever. The contact stated that the drive back to the residence was rough. Two or three days later, the gear shift lever failed to function as intended. The service warning light was illuminated. The vehicle was taken to an independent mechanic who diagnosed and retrieved DTC: P171D (For transmission pressure issue and oil leak). The vehicle was not repaired. The vehicle was taken to the dealer, where the contact was provided with the same DTC and informed that the transmission had failed and was leaking fluid. The vehicle was not repaired due to the cost. Upon further investigation, the contact learned that the failure might be related to missing bolts on the transmission accumulator. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 77,000.

After filling up fuel vehicle starts and stalls out. This occurs while driving at stop signs. And also while driving loss of power. There is something wrong in the engine, timing belt, fuel, etc.

Window will not go back up. Also when the windows are Locked ( Light indicator on) THEY STILL GO DOWN. My driver window was half way down and would not go back up. The Fuse was checked and Did not need to be replaced. Approximately 6 hours later window went back up.. WEIRD

The bolts connecting sections of the exhaust system broke off at 18 months. The bolts are not separate pieces. they are part of one side of the exhaust so you have to replace an entire section the the exhaust

When I'm driving sometimes the car seems like it's about to cut off or something & the check engine light plus stabilizer track message bones on & I start losing power & it's happened more than 10 times ! I let the car sit for a few minutes & it works !

The vehicle has a safety-related defect involving the safety restraint system. A warning message/light appears indicating a malfunction affecting occupant protection. This defect raises concerns regarding proper airbag and restraint operation in the event of a crash. I presented the vehicle for warranty service, but the manufacturer refused to diagnose or repair the safety defect solely because the vehicle was not currently registered. The vehicle is otherwise under warranty. No accident has occurred yet, but continued operation with this defect poses an unreasonable risk to the driver and passengers. The defect has been observed multiple times and remains unresolved. I am reporting this issue to NHTSA to prevent potential injury or death before an accident occurs.

The vehicle’s infotainment/display screen (center touchscreen system) malfunctions. The screen flickers, freezes, becomes unresponsive, and frequently fails to connect. The malfunction creates a safety concern because the screen controls critical functions such as navigation, rear-view camera display, Bluetooth/phone connectivity, and vehicle settings. When the screen freezes or flickers, I am unable to safely access navigation or hands-free phone features, causing distraction while driving and increasing the risk of an accident. The issue has occurred repeatedly during normal vehicle operation. There were no warning lamps prior to the malfunction. Symptoms include screen flickering, freezing, delayed response, and loss of connectivity. These symptoms began intermittently and have progressively become more frequent over time.
