Shift gear won't go into park. Emergency brake locked. Had dealer look at it and apparently a valve is blocked in transmission. Seen a number of complaints about transmission issues on this particular model yet this Vin is not on recall. GM says it needs a whole new transmission which will be $10,000. Really?? The least they could have done was fix this vehicle in good faith because of past recalls. Now I'm stuck with no vehicle and still paying for the finance.

The problematic 9 speed transmission failed at 72,000 miles on [XXX]. GM required a flush due to the significant shudder problems in the transmissions.

The transmission failed when traveling on busy highway in Aiken, SC on [XXX]. The money spent for these cars with failed transmission design/construction and the safety risk to all traffic must be addressed by the federal safety agency.

My vehicle starts displaying traction control on the dash then says reduced engine power and looses power starting until u stop turn it off and crank it back up. Sometimes it runs really rough and you have to crank it back up. The ac goes in and out on it, sometimes it jerks while driving, after having a new transmission put in, 3 starters, 2 batteries! Everyone keeps telling me it’s something electrical but can’t figure out what or where. Replaces mass air flow sensor also

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.

- Remedy
- GM will notify owners, and dealers will inspect the start-stop transmission accumulator and replace it if any bolts are missing, free of charge. The recall began December 15, 2020.

Recall number 20V668000 · Recall details
Power train: automatic transmission
- What is wrong
- General Motors LLC (GM) is recalling certain model year 2014 Buick Regal, LaCrosse, Verano, and Enclave, and Chevrolet Impala, Malibu, Cruze, and Traverse, and GMC Acadia vehicles equipped with automatic transmissions. In the affected vehicles, the transmission shift cable adjuster may disengage from the transmission shift lever. As such, these vehicles do not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 102, "Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect." They also fail to conform to FMVSS number 114, "Theft Protection and Rollaway Prevention."
- Risk
- If a vehicle's shift cable disengages from the transmission shift lever, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the driver may be able to shift the lever to the "PARK" position, but the vehicle transmission may not be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
- Remedy
- General Motors will notify owners, and dealers will inspect and replace any affected transmission shift cable adjusters, free of charge. The recall began on April 10, 2014. Chevrolet owners may contact General Motors at 1‑800‑222‑1020, Buick owners at 1‑800‑521‑7300, and GMC owners at 1‑800‑462‑8782. General Motors' number associated with this recall is 14048.

Power train: automatic transmission: lever and linkage: column shift
- What is wrong
- General motors is recalling 276,729 my 2009 buick enclave, chevrolet cobalt, hhr, malibu, traverse, gmc acadia, pontiac g5, g6 and saturn aura and outlook passenger vehicles. These vehicles fail to comply with federal motor vehicles safety standard 102, "transmission shift position sequence, starter interlock, and transmission braking effect", and fmvss 114, "theft protection and rollaway prevention". On some of these vehicles, the transmission shift cable adjustment clip may not be fully engaged. If the clip is not fully engaged, the shift lever and the actual position of the transmission gear may not match. With this condition, the drive could move the shifter to "park" and remove the ignition key, but the transmission gear may not be in "park".
- Risk
- The driver may not be able to restart the vehicle and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning.
- Remedy
- Dealers will inspect and ensure that the shift cable adjustment clip is fully engaged. In the event that the clip does not engage, the shift cable will be replaced free of charge. The recall is expected to begin on or before march 24, 2009. Owners may contact buick at 1‑866‑608‑8080, chevrolet at 1‑800‑630‑2438, gmc at 1‑866‑996‑9463, pontiac at 1‑800‑620‑7668 and saturn at 1‑800‑972‑8876 or at www.gmownercenter.com.
