2018 BUICK ENCLAVE

STEERING

Wednesday August 6th 2025, I was coming home from work, the low engine compression and engine light came on the car was shaking and I lost power on a busy road, I had to pull it off the road quickly before I lost all power. I stayed there for a few minutes, then turned the car back on to retreat to a safer spot, I then waited for my husband to bail me out, we checked the oil on the dipstick, there was minimal oil on it. We added 1 quart of oil, then the lights went off, all seemed fine. August 23rd 2025, I was driving my car and the same thing happened car lit up with low engine compression and engine light came on car was shaking, I shit the car off. we added 1quart of oil. But the engine light stayed on after about 30 min. I shut the car off. The engine light went off after I shut the car off.

I am a [XXX] and owner of a 2018 Buick Enclave that suffered a catastrophic transmission failure which nearly killed me and my child. On Friday, [XXX], while driving westbound on [XXX] from Edison, NJ to my home in Easton, PA, my vehicle suddenly and without warning came to a complete halt in the fast lane. A driver tailgating me swerved at the last second to avoid impact. Moments later, when I tried to move again, the car lost all power and drifted helplessly across two lanes of speeding traffic, directly into the path of two tractor-trailers barreling down at highway speeds. This was the hottest day of the summer, and I was left in terror, fully aware that one wrong move would have ended our lives instantly. The fact that my child could have lost their only parent because of a mechanical defect is beyond unacceptable. The stress, fear, and trauma of this incident cannot be overstated—it was a near-fatal event that never should have happened. My mechanic has since confirmed the transmission is destroyed, with black metal fragments throughout—clear evidence of internal failure. Only two months earlier, in June 2024, the car passed inspection with no codes or signs of a problem. This was not wear and tear; it was a hidden, catastrophic defect. In December 2024, GM recalled more than 461,000 vehicles, including certain 2018 Enclave models, for transmission defects leading to rollaway and internal failure. Source: The Lemon Firm, 12/18/24 [XXX] ). My case mirrors the defect exactly, yet I never received recall notice. I demand GM confirm my VIN’s inclusion and cover the full cost of repair or replacement. I barely escaped a fatal crash. GM must act immediately before lives are lost.

POWER TRAIN

The torque converter is failing it seems this is far too common and dangerous with all Buick enclaves for this year. The vehicle shakes when applying the gas not having the power it needs to keep a steady speed without shaking. A mechanic stated the torque converter is bad known as the “GM shutter”

FUEL/PROPULSION SYSTEM

Check engine light was on due to the EVAP Purge Solenoid not sealing properly and causing a leak. Scan testing performed of the engine control module and diagnosed/cleared DTC P0496-00. Vehicle was brought to a dealership for repair.
