Catastrophic engine failure. Piston #1 damage after a fuel injector issue. The truck just hit 100k miles. This left my husband stranded over an hour away. No check engine light or warning other than a loud pop and smoke. No warranty on the truck, I’ve been quoted $12k for a new engine. I have read multiple forums (one thread of 77 posts) of the same thing/similar thing happening.
The transmission shudders terribly. It is available for inspection. It is unsafe because while in traffic situations, it doesn't get up to speed correctly. It is as if it can't find the gear, it feels like it is about to stall. It is not dependable to stay at a speed, or increase speed. The dealership said that changing the transmission fluid would help, and it did for a while. The problem came back, we had the fluid changed again. The problem came right back again.
This is the 2nd time this has happened. The 1st time making a left onto route 23 from route 296 in windham NY. Almost got t-boned. Stalled wouldn't start. Waited 5 minutes and it started again. Ran rough then died again thankfully in a more opportune spot. My car randomly & without warning loses all power and electric and shuts down. The 1st time I had it towed to matthews GMC (where I purchased 4 pick ups) and they stated it was a nox sensor and repaired it. Saturday this happened again while driving at 55 mph and stalled on a blind curve (very scary). I left a complaint on this website to hopefully prevent a fatality. I thought I would recieve a response from you the ntsb but didn't. I went online and noticed there a a number of folks that had the same problem. Do you wait for fatalities before action is taken??.
Truck turned just over 62000 miles and appears to have engine oil cooler line failure. No oil on engine just dripping in protective plastic between radiator and engine. Spraying back underneath when moving. Checked on lone and blogs are showing many others with same problem with near catastrophic failure. I have dealer appointment for Wednesday August 4th 2021 to have it checked.
Torque converter fails at 12000 miles for many. There is a GMC notice out since 2016. Mine failed at 16000 miles and the one they replaced will likely fail again in another 16k miles. This is bad. I noticed it when I pressed on the accelerator and as I increased speed up to 45 mph. It rattled and rocked badly. The GMC repairman said, "yeap. . . . . Ever since 2016 all these damn torque converters have been failing in the Canyons and colorados because gm and chevy changed the size and strength of the metal used in order to reduce the weight of trhe vehicle. We will replace it, but I can assure you it will fail again and you'll have to bring it back to use for change out again. " wow. . . . What a bunch of crap.
