There were no symptoms prior to the engine failure. On January 14th, 2025 while driving 58 miles per hour heard a sound that sounded like a slap on the back window. After the slap sound I noticed the engine was not running as normal. There was also a sound coming from the engine like metal rattling around. A few minutes later the check engine light appeared in the instrument panel. Had the vehicle towed to the nearest GM dealership and was informed that the thrust bearing went out which may have caused damage to the crankshaft.

Took truck to dealer for diagnosis and repairs. was called and informed That the Coolant control valve was defective and that NO parts were available at this time, and that the expected part arrival dat was the third week of January. When asked if the truck was drivable was told that it wasn't recommended due to engine overheating concern and vehicle going into LIMP mode and leaving me in an unsafe situation if traveling on a highway or at freeway speeds.

Within weeks of buying the truck the Auto STOP/START quit working. I never gave it much thought until after a service visit and it was again working. I asked the dealer and they said the battery voltage dropped below a set level, turning off the Auto STOP/START. It quit again days later and has never worked again. There is no apparent reset. My battery voltage is normal, I have a REDTIGER F7N 4K Dual Dash Cam running 24/7 but it is drawing 4.5 to 5 watts; the car is rarely left parked for more than a day. I was initially bothered that there was no On/Off for the Auto STOP/START but I am even more frustrated that it is no longer working and no apparent reset short of taking the truck to the dealer for service.

I drove it immediately to the dealership and advised service. The next day I called the dealership for a status update and was advised the engine seized. The vehicle had 3,212 miles on it at the time. The dealership ultimately received permission to replace the engine which took about three and a half weeks. The vehicle is simply not the same and has several issues since. One was a No Start and No Power.

At approximately 9k mi the engine performance (2.7L MAX Turbo) started to become intermittent. I always record the fuel milage, and always drive the same way, to/from work. NOTE: Displayed mpg calculates within 1% of actual. We can assume the driving habits are identical each time. While driving on the same tank of fuel for a week at a time: one day heading to work the indicated mpg might be 17 mpg. Driving home, about 10 minutes into the drive, it might increase 25 mpg. The following day it could be the same 17/25 mpg or it might be 25/17. The weather is somewhat dependent, whereas around =<43F the 17 mpg is almost a guarantee. While the indicated lower mpg is displayed, a direct lack of engine power is noticeable. The accelerator is dangerously non-responsive, all the while of pressing the pedal >3/4 to the floor. There is also no downshifting from the transmission whatsoever. To make the engine respond to change, the accelerator must be fully pressed to the floor, forcing the transmission into a lower gear and causing the engine to 'wake up'. When the mpg is above 20 or 21 mpg, (and temperatures >50F) the engine performs normally, where gradual accelerations to the pedal increase the engine speeds and down shift as expected. I have contacted GM through the 'MyCheverlot' app a couple of times, and have taken the truck to the dealer twice for this. Both times from the dealer it was stated that since the engine light was not on and no codes were stored, there was nothing that could be done. The dealer installed a software update and sent me on my way. Lastly, the 4WD is now making a grinding/rubbing noise, since the software update and overcomes the engine power while making turns from a stopped position. If no acceleration is applied, the truck will come to a rapid complete stop if rolling <10 mph. Truck is a LEMON!!
General Motors LLC (GM) is recalling certain 2021-2024 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with a 6.2L V8 gas engine.
