general problems of the 2016 GMC Canyon

At random the power steering and traction control turn off making it difficult to drive. . This happens randomly and has become unable to steer. Once the vehicle is turned off for a period of time you can start it up and the steering returns. The issue was reported in the 2015 models. That recall needs to extend into the 2016 models since most of the parts were most likely manufactured tot eh same specs as the 2015. The vehicle was diagnosed by an independent repair shop. The dealership wanted $200 for just the diagnostics. Every time this happens it becomes very difficult to drive and is a safety issue. The issue first appeared 2 months ago and after the restart stopped. Then all of a sudden it seems to occur daily.

Transmission has been shuddering since 15,000 miles till now. Dealerships says it's normal on these transmissions, 6 fluid and filter changes and now at 72,000 miles the transmission is failing just outside of warranty. They scammed me and kept my transmission barely alive until warranty ran out and now they want 8k-10k for a replacement. They knew. Dash goes crazy from the touch screen to the digital information screen in the speedometer. They say it's normal and happens on all the units. But it's distracting and has been messing up since bought the truck new. Again they just kept saying it was nothing they can do. Now they say it needs to be replaced after my warranty has run out. Def system is failing conveniently after the warranty has run out. It's dangerous because they programmed the truck to go into limp mode when anything emissions related fails stranding me anywhere at anytime. Emission failures like sensors should not restrict travel. This is a major issue with the diesels in these trucks and they need to be forced to remove anything that's not dangerous to the health of the engine or drive train from the software or hardware from being able to restrict travel. In every situation I've been restricted to limp mode by dirty particulate sensors, but the code that pops and puts my truck in limp mode says that the nox sensor is bad. This is false and is just a way for gm to get service at their dealers. Then they charge customers a fortune to replace parts that don't need to be replaced when you can just remove and clean the four particulate sensors and the restrictions will clear themselves shortly after. Emissions related issues should not restrict travel by any means! it is dangerous to be stranded on a trip because your emission sensors may be malfunctioning.

Complete loss of power steering and traction control while driving. Very difficult to make turns. Would have to pull off the road and restart vehicle to fix problem. I have not taken it to a service center. It has not been inspected. Warning lights for loss of stabilitrak do come on.

I have not been in an incident yet, but when I slow down coming off the highway and try to come back up to traffic speed the the transmission bucks or shutters. Also when starting from a red light or stop sign the truck bucks or shutters very notable in 3-4-5th gear. I watched the tachometer and it shutters most of my drive. In all fairness, I have not brought it to the dealership yet. I see other people are having this problem with the Canyons and colorado also. Please advise!.

Driving and the stabilitrak warning comes on as well as the power steering warning. Later after the vehicle is turned off it will not restart (no crank, no start) and there is no communication with the ecm until it has had the battery disconnected for an extended period. This is very dangerous losing power steering and stabilitrak while driving is going to cause an accident. I would like to see a recall on the 2016 like there is on the 2015 with this same issue. I have not had the issue repaired yet. Waiting to get it into a shop who tells me they will likely need to replace the rack and pinion on this truck to correct the issue.

Key is not pulling out of ignition after truck has been put in park. Mechanic has replaced the shifter twice, and yet the problem is more pronounced. The dealership (anthony GMC) has now stated there is no problem, and yet the key wont come out for them either.

•water coolant valve, and torque converter. •my truck temp gage will fluctuate towards red line and back to normal. Torque converter caused my vehicle to shake, vibrate, slow accelerating, made it seem vehicle will shut off on highway or in heavy traffic. •I went to several mechanics, including the dealerships and they fixed my water coolant valve but issue persisted, the dealerships said my truck was running fine until I had requested to ride along with mechanic, that's when he guessed it would be torque converter. •has not been inspected, just test drove and replaced by mechanic •no lights indicated on dash board and I felt the shake and vibration around 08/01/2021 and reported to dealership. The water temp gage was reported back in Nov 2018 but the problem still persist.

Ignition key randomly will not release from switch. The key is stuck in the ignition in the accessory position which in turn kills the battery. As far as I can tell (and I have read about and experienced this problem for many months) the root cause is the gear shift assembly or part # 23397472. It is not reliably returning the confirmation, to the solenoid lock on the ignition switch, that the transmission is in park reliably. For the first time last w/e my dealer admitted this is a problem and that replacing 23397472 usually resolves the issue. I need gm to take responsibility and activate a recall.

Have had truck in shop several times, currently in the shop and has been there for almost 3 weeks nobody seems to know what the problem is. Vehicle losses power and goes into a limp mode. Temperature gauge keeps failing, exhaust break does not work, ac cuts out often and does not work often, keeps trying to clean exhaust filter over and over again and again.

Vehicle frequently shuts off during braking or while stopped and must be restarted before the vehicle can operate again. Vehicle experiences violent gear changes and significant lagging during periods of moderate acceleration at low speeds. Gear changes result in either severe unresponsiveness and a general lack of acceleration or an aggressive gear change that jerks the vehicle and spins the tires.

Ignition will not fully turn off and release key when truck is placed in park. I'm addition ignition and key become very hot to the touch after driving for over 20 minutes (temp outside is cool 50-60�). Truck will eventually turn off and release the key after restarting and shifting through all gears multiple times (turning off, back on, shifting, etc. ). Already attempted cleaning keys (both sets) with no change in behavior.

Traveling down city street approx 35mph vehicle unexpectedly shut off, dash went dark but infotainment system continued to work. Loss of all power. Brakes shuttered when attempting to come to a stop. Put the vehicle in park, turned it off, and back on. Vehicle drove normally after that.

Vehicle has frequent slow acceleration when entering highways. I have to step on the accelerator hard to have the engine pick-up speed, which leads to the engine over accelerating. When I slow down on sharp road turns and accelerate to pickup speed the transmission shifting the gear hard (making a thump sound). Have gone to dealer at merced GMC and turlock Chevrolet. Both state car is running the way GMC manufactured it.

While driving, the engine picks and chooses when to speed up. I press the gas peddle down and have to wait a few seconds before the vehicle responds. I have noticed the vehicle making sounds like it is sputtering almost to the point to seizing all together.

Transmission shudder that is causing drivability issues. Multiple mechanics have told me to drive it and maintain it until the transmission gives out.

Slow and go driving 20-40mph after coasting and trying to accelerate again the transmission bucks hesitates trying to find a lower gear. It can't decide which gear to go into and just sputters and chugs until I push the accelerator 1/2 way down or more the finds its gear and rockets off. This type of driving not safe at all. This happens all the time since practically new. Gm claims its normal. Bulletins to not fix anything except update the software. That doesn't accomplish anything. This is a known gm issue with colorados and Canyons and gm changed transmissions following years and no support for 2015-16.

Unpredictable acceleration limits drivers ability to safely merge with traffic or change lanes. Vehicle can take up to 3 seconds to begin acceleration after gas pedal is pressed and then can surge unpredictably. I have seen this issue reported in GMC forums by others. GMC says there is nothing wrong.

Transmission seems to be confused. It will hesitate during acceleration and shift up and down while coasting. Most sluggish shifting occurs during lower speeds. It also has a habit of downshift to low gear while coasting downhill. Always seems to be fighting with itself!.

The contact owns a 2016 GMC Canyon. On several occasions, while driving, the accelerator pedal was depressed and the vehicle failed to respond. The contact stated that the vehicle would then shift into gear extremely hard. The vehicle was taken to rimrock GMC Cadillac (located at 840 shiloh road, billings, mt 59106 (406) 651-5000) to be diagnosed. The mechanic was unable to retrieve a fault code or duplicate the failure. The manufacturer was notified of the failure. The approximate failure mileage was 11,635.

Tl the contact owns a 2016 GMC Canyon. On several occasions, while attempting to accelerate, the vehicle failed to respond. The vehicle was taken to gay Buick GMC (3033 gulf fwy, dickinson, TX 77539, (832) 769-4378) to be diagnosed, but the dealer stated that the vehicle was operating as intended. The contact was also informed by the mechanic that the vehicle should be placed in trailer mode to rectify the failure if it happened again. The contact was concerned that the vehicle could cause a crash. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 7,000. The VIN was not available.

Vehicle bogs and misfires at rpms below 2000 causing a significant safety problem. Vehicle refuses to accelerate at low rpm unless it downshifts. Research on the internet finds multiple complaints for the same issue. I test drove a 2017 GMC Canyon and it exhibited the same issues.

I bought a brand new 2016 Canyon, test drive went well, although I admit it probably wasn't long enough. Purchased on Sunday, and during the next week driving I began noticing the transmission was not shifting at the proper times. Like most people on here, the transmission appears to be very confused , especially when decelerating into the 20-35 mpg range and attempting to re-accelerate back up. It will misfire or be very unresponsive, and then clunk and jerk you forward once it decides to change gears. It also does something that I think is even more dangerous when you are going around 30-40 mpg and then simply let off the accelerator. In this instance, I feel like it down shifts instantly and it feels like the truck is being pulled back (instead of simply coasting like I would want), and then at some point it "releases" from this and the truck actually stops decelerating and speeds up a bit, even though the gas had been released many seconds ago. This is particularly dangerous in stop and go city traffic. I think the overarching problem here is the shift points that the ecm has determined (or been programmed with). You can tell this when accelerating from a stop, my truck gets to third gear by 15 miles per hour and never goes above 2k rpm's??? I admit I am a bit light-footed on driving, which compounds the problem because I eventually am giving a small amount of acceleration to a truck in 4th gear only going 20 mph, which suck. I have also read this was a common problem on 15 Canyon (obviously read after purchase), and GMC eventually came out with a few fixes, including ecm patch updates or lower valve replacement. I imagine that many of the 2016's were already off the line by the time these '15 fixes came out (in April 15 I believe), but the dealerships have not received any of these for the 2016.

Transmission hesitates dramatically between some shifts. . Long periods where transmission seems to be in neutral. Typically happens in lower gears, such as between 2 and 3 gears. Pressing accelerator them causes a clunk into gear. Also, on higher speeds, downshifts are slow to occur but then several gears seem to be skipped when the downshift finally occurs, with screaming engine rpms. This is a 4 cylinder model with 6 speed automatic trans.

The transmission does not shift properly, when you slow down from approx 40 to 20 then step on the gas the truck has a long hesitation. It is very unsafe and is going to cause an accident. The truck wants to stall out unless you floor it.

The transmission does not downshift from a high gear (5 or 6) to a lower gear when slowing down from 45 mph to 20 mph (or lower). When the accelerator is depressed to accelerate the engine bucks, vibrates, and does not accelerate. The engine rpm drops to 1,000 rpm or lower. If the accelerator is quickly floored the transmission downshifts several gears lower and jerks forward. This condition happens primarily on secondary roads while driving along the road and when pulling from one road into traffic on another road. The situation when pulling into traffic is dangerous because the truck does not accelerate as it should.

The contact owns a 2016 GMC Canyon. While the vehicle was stationary, with the brake pedal depressed, the rpms suddenly increased and the vehicle erroneously attempted to drive forward. Also, while decelerating from approximately 15 to 20 mph, the vehicle shook and shuttered when depressing the accelerator pedal and would not accelerate as normal. The cause of the failures was not diagnosed or repaired. The manufacturer and local dealer were not notified of the failures. The failure mileage was 1,000.

The throttle and transmission feel as though they were separately developed for two different vehicles and just randomly matched in the truck. The accelerator is very non-linear and unresponsive. Then the transmission is constantly in the wrong gear. This truck is a nightmare to drive in traffic or on windy hilly roads. You have to constantly guess where your foot should be to get any kind of stability or acceleration from the truck. If you are trying to pull out in traffic you better be prepared to have a lot of room because it might just shake and shutter before finding a gear and actually accelerating. This is dangerous and I find it odd that there havent been collisions attributable to this. If anyone from gm is reading this, know this will be the last gm product I ever buy. Either you dont know how to engineer a vehicle, or you simply just dont care about your customers. Im guessing the latter.

My truck will I engage into four wheel drive all by itself . Its been to the the dealership nine times and I'm feeling very uncomfortable driving this vehicle. If this vehicle goes into four wheel drive while I'm on a major highway it could be unsafe to my life and others that are driving with me. But the dealership is not taking this problem very seriously I think. This problem is this going on. Reference number 11012598.
