This is 2nd $40,000 canyon I've been taken for! 1st was 2016, and transmission would take off after flooring it, as it would just 'lay down' and scared the wife so much, and wouldn't drive it! Had to repurchase an 2017, with the 8 spd trans, and even worse! It shakes and shudders even after fluid flush, then new torque converter! Then was told, there's nothing more gm can do for you!?? Really? Now gm is not responding to multiple calls! $43,000 truck really? Never again, these vehicles should not be on the road! Was promised to have this resolved this afternoon,10-28-19, and once again no return calls! Will seek real council in am, as gm resolution is a joke! Don't waste your time, go strait to qualified firm.

Tl* the contact owns a 2017 gmc canyon. While driving various speeds, the vehicle shuddered and vibrated when the accelerator pedal was depressed. Afterwards, the vehicle accelerated rapidly without warning. The vehicle was taken to key chevrolet (32 key auto dr, white river jct, vt) where the transmission was flushed and the torque converter was replaced, but the failures continued. The contact stated that after two repaired when pulling ut into traffic still hesitate and shakes. The manufacturer was notified of the failures and provided case number: [xxx]. The failure mileage was 28,000.*pm *tp 'parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).'
2017 gmc canyon equipped with diesel engine will sporadically shut-off while operating when driving with a tank that is less than 1/4 full. On 1/31/19 (odometer ~14200 miles) vehicle was driving fine with an ambient air temperature of roughly 0f, fuel tank at 1/3, when all of sudden the engine died in traffic with no warning. Vehicle then needed to be towed to the dealership for service at which point they couldn't find anything wrong with it. Again on 3/4/19 (odometer ~15100 miles) vehicle was driving fine when the dash lit up with multiple codes and truck went into reduced power mode, ambient air temperature 10f gas tank at 1/8th. Got out of truck and it smelled like it was on fire. Called to have vehicle towed to dealership. Vehicle kept for multiple days at dealership, dealer worked with gm to identify an issue and no fix was found. Dealer called to instruct me to not drive the vehicle with less than 1/4 tank during winter and also mentioned that this has been an issue with a few other canyon and terrain diesel models. Gm needs to find a fix for this! It is totally unsafe and unacceptable to have a truck that will unexpectedly loose total power when driving due to a design flaw in their systems.
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 [xxx] 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.

Transmission began shifting hard. Before long whole truck rattled when shifting. Almost a grinding sound. Chevy diagnosed torque converter has gone bad. Back ordered for 2 weeks.
The gmc 2017 canyon vibrates at highway speed 60mph to 70mph. The 2nd day after I bought it took it on long trip found it had vibration problems. After taking it to the dealership for tire balance twice replaced front wheel bearing then transmission flush. Then after transmission flush had vibration between 40-45 they said it was normal that there was nothing else they could do. Due to vibrations over time this concerns me. For being stranded or worse causing an accident from something coming loose. I`ve already had to tighten up my spare tire. I bought this pickup for long trips since I`ve retired. Like the one my wife and I are going on in june of this year. I also feel if there going to sell crap like this they need to put the vibration issues on the accessory `list so buyers will have the option whether to buy or not. I would have not bought a $40,000.00 vibrator!!!
