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.

We purchased our 2017 Chevrolet Suburban premiere 2018 at clay cooley, irving, tx and have completed every maintenance service required. When we purchased the vehicle in 2018 the certified Chevrolet Suburban premiere had 50, 000 miles. As of 11/23/20 our truck began slipping when pressing down on the accelerator pedal while driving on the highway. The truck was pausing before acceleration and noisily idling. We took the car to the dealership the next day and was told our transmission need replacement and will cost us $6, 000. Our current onstar report never reported engine problems, but only suggested maintenance due at 112, 500 miles reported 11/15/20. Our pedometer read 110, 800 miles presently 11/23/20. The service representative said we had all of the service done last month but will check it out. This is a faulty vehicle that is not safe as Chevrolet make claim these vehicle to be for family and long distance traveling. Buyer bewate and do not spend your money on this high end 2017 Chevrolet Suburban premiere.

This vehicle keeps having key fob, electrical issues, tire service maintenance issues, and now engine issues related to the key fob. The key fob keeps saying it is not detected. Recently, while driving on road at about 48 mph, key fob notification came on dashboard saying key fob was not detected, engine shut off and car had to be restarted again using fob box inside glove compartment, this was particularly alarming. The key fob has had batteries replaced and they work because the car will remote start and have tried batteries in other items. The fob does not however let you unlock the car or finish starting it out of the remote start once you get into the car and try to start it, the car tells you it cannot detect the remote. The car has had numerous key fob issues and has been taken into local Chevrolet dealer who cannot find issue. The car has also had 142 hard braking events since April 2019 to November 2019 according to on star reports. The tire service monitor keeps flashing that there are issues with tires. The rear wiper would not shut itself off even though button was in off position. All of these issues have not been able to be repaired at the Chevy dealer. This car is going back in for service 11/18/19 for these issues again. Not sure what the outcome will be until after this appointment. My guess is that it is some kind of electronic circuitry problem(s) but unfortunately the dealer says they cannot find any issue(s) or problem(s) until it completely shuts down. These events are ongoing and have been occurring intermittently since November 2018. All I can provide is photos of the dashboard showing what it relates to me unfortunately I have no documentation of engine shutting off only a photo of what dashboard showed when it happened.
