This Problem Across All Years
2018 Yukon Denali engine failed June 2024 due to the lifter being bent. The dealership Richey Cadillac in Daytona Beach estimated the repairs at $18,862 and were going to have my vehicle for months. I took it to my mechanic who rebuilt the engine for $7181 in 30 days. My safety was placed at risk because while driving I had to pull over since I had no control with the engine failure. There were no messages prior to the failure.

The air-conditioning (A/C) unit in my 2018 GMC Yukon XL (my vehicle) is not blowing as cold as usual. The dealership (Westpoint GMC) where I purchased my vehicle says their A/C department is backed-up and that I would need to leave my vehicle with them for 2 to 3 days to run diagnostics. I took my vehicle to another General Motors dealership instead, Westside Chevy, and their A/C department or technicians state that my vehicle has a leak in the rear evaporator coil after running their leak detection tests. I purchased my vehicle new on May 4, 2018, and have not any mechanical issues nor heating, ventilating, air-conditioning (HVAC) issues since ownership. This mechanical flaw / malfunction / disruption in the cooling comfort of my vehicle during this extremely hot weather puts the life of other drivers and myself at risk of injury or fatality due to discomfort and inconvenience while driving. There are no alerts or alarms associated with the failure of this mechanical component within the HVAC of my vehicle. This condition first appeared on September 30, 2023. I understand that a possibly similar or related investigation in other GM vehicles took effect in February 2016 under Technical Bulletin 16-NA-046. Is it probable that there is a design flaw within the 2017-2019 GMC Yukon, Yukon XL and other similar builds HVAC?

It’s starting to warm up now that winter is behind us, so when we recently drove our 2018 Yukon XL, we turned on the air conditioning. Unfortunately, only warm air came out of the vents. We made an appointment and took the Yukon to the GMC dealer. We paid over $160 for their diagnostic fee (complete rip off), and they were immediately able to see that there was a leak in the AC condenser. The dealer service representative said that this has been happening quite frequently on 2014 and newer models and that they are all leaking in the same place, a weld on the driver’s side of the condenser. Our Yukon has $59,000 miles…this is way to young for a condenser replacement. Dealer is quoting us over $1200 for the repair. GMC continues to build these cars without known defects and passes on the costs to the customer! By the way, there is Special Coverage Adjustment 17336 that extends warranty coverage for this specific problem on GMCs, but only for 2015-2017 models.
