The contact stated that while driving approximately 60-65 MPH on the interstate, the vehicle was shuddering abnormally while accelerating, and the transmission failed to properly shift into gear. The contact was concerned about safety while driving the vehicle at highway speeds. There were no warning lights illuminated, or messages displayed prior to the failure. After the most recent failure, the vehicle was driven to the residence. The vehicle was taken to a dealer to be diagnosed; however, the dealer was unable to duplicate the failure.

The vehicle was taken to an independent mechanic, and several unknown diagnostic trouble codes were retrieved. The vehicle was then taken to the dealer, but the vehicle was not yet diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 20V588000 (Service Brakes); however, the VIN was not included in the recall. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 81,000.

The turbo in my vehicle has a check engine light come on and than the engine does no act right. The repair shop that looked at car stated that the manufacture knows this is a known issue and they have not made a recall as several cars my year range has this going on. If this is a known issue why is there no recall. I worked had for my car and I can not afford the repair of a know issues with the turbo as it cost a lot and I should not have to cover this as it is apparent this is a manufacture defect that is known. It puts me as risk as the car is not preforming properly and it jumps and does not go properly when it has the issue arise. I will get hit for not going after I come to a stop and will not accelerate properly. This issue appeared 2 months after I purchased the car and I took it to a shop who told me he has tried to contact Buick to cover the repairs for others and gets no where. I think that the manufacture knows and will not repair something that is not the owners fault but there shafty part and they know this as it was a recall in other years of my vehicle.

I was driving ~72 MPH on the interstate and my car suddenly downshifted and the dash read “Speed limited to 62 MPH”. I took the nearest off ramp and the brakes completely failed. The dash initially read “service transmission” and “service breaks”. After restarting the Buick Envision, the MyBuick App diagnostics stated “service breaks” only. The car was towed to the dealership this date. I have not heard from them on what has caused the brake failure yet.

The contact owns a 2020 Buick Encore. The contact stated that while driving at an undisclosed speed, the brake pedal and accelerator pedal became extremely hot to the touch. The contact became aware that the silver heat shield was missing. Additionally, the contact stated that there was electrical activity or electricity coming from the area. No warning lights were illuminated. The vehicle was taken to a local dealer; however, the dealer was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 77,213.

Lateral arms needed replaced at 60,000 miles causing shaking, accelerated wear on tires, increasing misalignment.

Subject: Complaint Regarding Improper Handling of Safety Recall Repair Hello, I would like to file an official complaint regarding a dealership that failed to properly follow required procedures for a federally mandated safety recall repair on my vehicle. Vehicle Information: • Year/Make/Model: 2012 Buick Lacrosse • VIN: [XXX] • Recall Number (if known): Dealership Information: • Dealership Name: Castle Buick • Location: 7400 Cermak Rd, North Riverside, IL 60546 • Date of Service Attempt: May 2026 Details of the Issue: The dealership did not follow the proper safety recall repair guidelines as required under federal regulations. Despite the recall requiring specific corrective actions to ensure the vehicle is safe to operate, the dealer either: • failed to perform the full recall procedure, • refused or delayed the repair without a valid reason, or • returned the vehicle without completing required steps to ensure safety (such as proper inspection, adjustment, or alignment). This violates my rights as a vehicle owner, as federal law requires manufacturers and authorized dealers to correct safety-related defects at no cost and in full compliance with recall instructions. I am requesting NHTSA’s assistance in ensuring that the recall is properly completed and that the dealership’s non-compliance is investigated. I am concerned for my safety and the safety of others on the road. Contact Information: • Name: [[XXX]] • Phone: [[XXX]] • Email: [[XXX]] Thank you for your attention to this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2016 Buick Cascada. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal squealing sound. The vehicle was subsequently taken to the dealer, where it was diagnosed with a PCV valve failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 19,000.

The turbo failed by reducing speed all a sudden when I was driving on the freeway. Got the problem repaired and not even a month later same thing is happening again.

On June 22,2026, I was involved in a frontal impact collision while traveling at approximately 35 mph. The vehicle suffered a catastrophic failure of the entire occupant restraint system. Despite a severe, high-speed frontal impact, the frontal airbags failed to physically deploy, and the seatbelt pretensioners failed to tighten, leaving the seatbelts completely loose. Crucially, the dashboard instrument cluster displayed a message indicating that an airbag deployment event had occurred. A check of the VIN shows no open recalls, meaning the GM SDM software update (NHTSA Campaign 16V651000) was likely marked as completed by a prior owner. However, the system completely failed to function as designed during a major crash, mimicking the exact symptoms of the original defect. The vehicle is currently held at a private tow yard pending an insurance investigation and an Event Data Recorder (EDR) download.
