This vehicle has experienced repeated and ongoing serious defects with the 8L90 Transmission Torque Converter. I took delivery of this vehicle on 17SEP2016 and since it has required multiple service appointments to address the issue. To date it has not been satisfactorily repaired. Despite repeated failed repair attempts the vehicle exhibits erratic transmission slipping, jerking, hesitation and surging under acceleration. These symptoms persist even after a most recent torque converter replacement (and subsequent re-replacement as outlined below). This creates a serious safety concern particularly when accelerating into traffic, merging and driving uphill, but also in low speed maneuvers such as navigating a parking lot. The vehicle often feels like it is misfiring under acceleration when trying to merge, then surges forward erratically. In parking lots at low speeds, the downshift of this transmission is so abrupt that it often causes the driver and passengers alike to believe that the vehicle has been hit from behind. The repair history started within 2 years/24K miles as follows: - 01FEB2018 @ 28140 - Drain flush and fill transmission for Shudder/Hard Down Shift - Diagnosed as Torque converter issue. This helped for a short period of time - 26JUN2019 @ 53445 Miles - Same issue - same diagnosis - same repair attempt - this was unsuccessful in anyway. - 12NOV2019 @ 60653 Miles - Same issue and diagnosis - Torque converter replaced - 31JUL2024 @134218 Miles - Same issue and diagnosis - Flush and fill recommended since extended warranty had expired - paid $300 for transmission fluid flush and fill - 15APR2025@145963 Miles - Same issue and diagnosis - Torque converter replaced for $2956 - there was no appreciable improvement - 08AUG2025@151182 Miles - Torque Converter replaced under warranty from 15APR2025 work - No appreciable improvement - 20AUG2025@151500 Miles - Same issue - Advised to replace entire transmission

Torque converter

5th and 6th gear in the transmission quiet working due to the torque converter being bad while I was driving down interstate which caused the valve body in the transmission to go bad

Transmission completely destroyed. Transmission known to have various problems had in shop twice and still not right! Total cost so far is 4800 dollars

The transmission failed prematurely (just over 95,000 miles). Before i had it rebuilt, It was lurching forward as I was coming to a stop. It also had trouble switching gears (very rough) and a loss of power. I understand this transmission is part of a class action lawsuit. I wanted to make sure my experience was documented with the other cases. General Motors needs to correct this problem and reimburse owners for work already completed. I will dig up my transmission repair documentation and include it with this record. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission problem. Harsh and clunk noise when shifting. Hesitation when accelerating and when shifting to reverse. It only has 70,000 miles the dealer wants 7 to 8 thousand to fix it.

I have had to replace the transmission in this vehicle 3 times within a year and half time frame. Initially experienced harsh shifting, significant hesitation in shifting and the transmission overheated whilst driving on the highway to the point where smoke was clearly visible. Each of the 3 failures stemmed from the torque converter. There were no warning lamps or messages present prior to the failures.

Transmission shifts erratically, sometimes violently. It seems to shift through several gears within seconds. There is no warning lights or codes that appear. I was rolling in line to exit a parking lot, going less than a crawl, and transmission shifted. It sounded like I had been rear-ended and vehicle lunged forward. There was enough distance that I was able to avoid the vehicle that was in front of me.

Transmission valve body failure, first failure around 28-30000 miles, second failure at 44,000 miles. Truck has been at Chevy garage for two weeks, I still have no answer on part or remedy

See attached document for complaint.
