Transmission experiences torque convertor shudder. with very hard shifts at 5 and 18 mph. dealer complied with bulletin 18-na-355. had improvement in shift for a while. then hard shift return at 5 and 18 mph. during decelerations there would be a shudder. when using cruise control when reducing speed transmission would shudder. return to dealer, when oil pan was removed found aluminum chips and one metal chip. dealer replace with remanufactured transmission. drove vehicle home. then went out and drove the vehicle upon exiting drive way experience torque convertor slippage at around 12 mph with engine rpm going from 2000 to 4000. continued to drive vehicle once torque convertor reengaged. continued driving made couple of short trips in traffic continue to experience banging in drive train. i believe this vehicle puts my safety at risk
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.
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.
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. 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).
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!!!
