BUICK Complaints

The contact owns a 2014 Buick Lacrosse. The contact stated that after the vehicle was turned off, residual electrical power activated in the vehicle. The power windows and sunroof remained operational, and the instrument panel remained activated. The vehicle was taken to a local dealer, who diagnosed that the driver's door window switch was faulty and needed to be replaced; however, the vehicle was not repaired. The contact was informed that the VIN was not included in NHTSA Campaign Number: 14V317000 (Electrical System); however, the contact related the failure to the recall. The manufacturer was not yet notified of the failure. The failure mileage was 115,000.

While driving check engine suddenly illuminated following by a "warning reduced engine power" message. Car began driving sluggish and driving over 35mph caused serious trembling. After multiple diagnosis with several engine codes pointing to issues with ECM, and mass air flow sensor, and the wiring affliated . I took the vehicle to the GMC dealership to get vehicle serviced and was told the wiring had broken and melted which caused the check engine to come on and the vehicle to drive the way it did. The cause was the zip tie being tied too tight as stated in GMs own bulletin number 22-NA-008. This should be a bulletin it should be a recall!

Traction stabilization light comes on very frequently and vehicle loses power, step on gas and it sputters can’t get out of any one’s way, they throw parts at it and never fixes. From feedback off internet a big problem 2008-2017 enclaves

Car purchased new in Nov 2018. Within 3 years needed a turbocharger replacement. At this time this was covered under warranty. Recently had to undergo replacement for the turbocharger again. This time it was not covered under the warranty. In researching this problem I saw that in Feb of 2024, Buick extended the warranty on the Buick 2017-2018 Encores, due to a manufacturer defect in the turbocharger. This add'lwarranty covered the cost of the repair & was good for up to 120,000 miles. Since we purchased the car in 2018, the parts used to build it had to be the same as those used on 2018 Encores. Asking to see what we can do to see if this car, under these circumstances qualifies for the recall.

I am submitting this complaint regarding a paint defect on my 2020 Buick Enclave. The passenger-side rear door has significant top-coat peeling and flaking, exposing the primer and metal underneath. This deterioration is not normal wear for a six-year-old vehicle that has been properly maintained and protected from environmental conditions. The pattern of peeling indicates a failure of the top coat or clear coat applied during manufacturing. The paint layers are separating prematurely, reducing corrosion protection and long-term durability. Exposed metal increases the risk of rust, structural weakening, and potential failure of the door panel, which may affect occupant safety in the event of a collision. I am aware that similar paint adhesion failures have been reported across multiple General Motors vehicles, and class-action lawsuits are currently pending alleging defective basecoat and clearcoat systems that cause premature peeling, bubbling, and flaking. The number of complaints suggests a broader manufacturing issue rather than isolated consumer misuse. Although my vehicle’s limited warranty has expired, the defect is clearly premature and manufacturing-related. A properly applied top coat should not fail this early, especially on a vehicle that has been routinely washed, waxed, and stored in normal conditions. I respectfully request that NHTSA review this issue and consider opening an investigation into paint top-coat failures on Buick and other GM vehicles. Premature paint failure affects corrosion resistance, vehicle longevity, and consumer value, and may compromise the safety of occupants and other drivers if corrosion spreads or structural integrity is reduced. I am willing to provide photographs, documentation, and maintenance records to support this complaint. Thank you for your attention to this matter and for your commitment to consumer safety and manufacturing accountability.

A squealing sound was coming from the top of my engine and I had low/rough idle and it progressed to a low voltage output and check engine lights. This happened while i was driving on the highway and my speed was eratic and I had to cross 2 lanes to get the next exit. The problem has been reproduced my an indepent service center. The PCV vent constantly pulled vacuum (was stuck open to atmosphere) and the sound was only relieved by removing the dip stick. No warning lamps messages or symptoms. There is NO part number difference in the Camshaft cover between model years 2016 thru 2019 Cascadas. I believe that the 2018 should be included in the same Special coverage as the 2016 and 2019 model years. This issue has been noted in several Casada forums and is also the same as NHTSA complaint IDs: 11593462, 11587414, 11574318, 11515179.

Battery went completely dead during long distance drive, check engine light came on for fuel pump, back right tire went flat only 4k miles on the vehicle

Vehicle is a 2018 requiring valve cover replacement due to an issue that was recalled on previous years, most recently 2016. Extended warranty was offered for these repairs. TSB Special Coverage N192291620 – Camshaft Cover Replacement (later superseded by N232395320). This should be reviewed for additional recalls.

Driving home from work on interstate, 2 month old 2026 Buick enclave jolted and shut off completely while going 65mph. Barely pulled over safely to the left side (Oklahoma drivers). Restarted car, check engine light illuminated with messages of reduced engine power (limp mode up to 35mph) while stuck on highway, traction control and esc disabled. Was able to get off highway and limp to nearest GM dealer. They performed diagnostics 3 days later and replaced the fuel rail pressure sensor. It did not fix it. More codes according to dealer and they are involving engineers. Moving next week on military orders and car is still being worked on with no estimate of time to complete. Insanely concerning safety hazard for a brand new car to shut off on the highway. Could have died or killed others in accident. Unable to invoke lemon law yet but not comfortable driving the car again especially across the country on limited time.

a software glitch that causes the instrument panel display to intermittently black out or go completely blank. This safety recall (NHTSA Campaign Number 23V744 / GM Recall Number A232424320) impacts the vehicle's electrical system, specifically targeting the Virtual Cockpit Unit (VCU) module. Core Issue & Symptoms Blank Dashboard: The primary symptom is an instrument panel that intermittently blacks out.
