Component or System Failure The vehicle experienced two major mechanical failures. First, the transmission failed and required full replacement shortly after the expiration of the 60,000-mile powertrain warranty. At the time of this failure, the vehicle had approximately 61,000 miles. Second, at 100,119 miles, the engine suffered a catastrophic failure that required complete engine replacement. Safety Risk The transmission failure impaired normal drivability and created a safety risk due to reduced or unreliable propulsion, which could have resulted in loss of power while driving in traffic. The engine failure rendered the vehicle inoperable and could have posed a serious safety hazard if it had occurred while the vehicle was in motion, including sudden loss of engine power. Problem Confirmation and Inspection Both failures were diagnosed and confirmed by dealership service personnel, who determined that full replacement of the transmission and later the engine was necessary. The issues were identified through inspection and standard diagnostic procedures. Warning Lamps or Symptoms There were no clear, persistent, or meaningful warning lamps, messages, or symptoms that would have reasonably alerted the driver to an impending transmission failure prior to it occurring. Any warning indicators appeared at or immediately before the failure. Similarly, there were no significant warning signs that would have predicted the engine failure prior to the need for complete replacement. Additional Information Both the transmission and engine failed at relatively low mileage for major powertrain components. The transmission failure occurred just beyond the powertrain warranty threshold, and the engine required full replacement at 100,119 miles. . These failures suggest a potential defect or durability concern affecting critical powertrain systems.

The condenser has a faulty design and cracks, causing it to leak flammable R1234YF coolant in the engine bay. Additionally, this leak causes the AC system to stop cooling, thus making the inside of the vehicle a very dangerous place, particularly during summer months, as it is impossible to cool. There are thousands of reports of this issue on all Chevy/GM models between 2015-2020 including tahoe, silverado, suburban, and yukons. The manufacturer has put out a "special coverage 17336" adjustment but it only covers the vehicles up to 60,000 miles and because it's not part of a recall it's not automatically sent out to the owners of the vehicles. Further, a large number of vehicles are well beyond the 60,000 mile limit in the special coverage before the owner ever learns of the issue. According to SAE J1739, "Manufacturers must conduct Failure Mode and Effect Analysis (FMEA) as provided in SAE J1739 (adopted 2009). Manufacturers must keep the FMEA on file for at least three years from the date of creation." I would challenge that chevrolet did not do this FMEA testing or did not do it per standard as it would have shown this issue. Instead they moved forward with production affecting hundreds of thousands of their most popular vehicles from 2015-2020 and resulting in the consumer having to pay an average of $1100 in repair costs due to a known defect from the manufacturer.
