Ignition locking solenoid fails to release when put into park, resulting in the key stuck in the ignition. I'm then unable to leave the vehicle unattended without threat of theft or battery failure. Dealer has not been able to fix the issue. No warnings or failure indications are observed, other than the key being stuck.

GMC Service Bulletin - PI1429B Ignition Key cannot be removed and /or does not rotate to the off position. If you place the truck in park and turn off the switch - the key does not rotate to the off position (it only goes to the accessory position) so you cannot remove the key. You have to start it back up and move the truck forward and backward a number of times until the key is able to be removed. There are numerous posts on GMC and Chevrolet forums throughout the internet on this same issue. Cannot imagine why this safety concern is not being addressed with a recall. Gear shift assembly or Part # 23397472 is the most common posts. This happened numerous times but on 03/23/2022 it has happened every time I have tried to turn the truck off.

Key gets stuck in the ignition switch. Truck will turn off but key will not come out. It is sometimes hours before the key will release. The dash lights stay on during the period the key is stuck and the battery dies. I have to leave my truck unattended, for extended amounts of time, with the key in the ignition. This has been going on since two years after the purchase of the truck, as new, in 2015. Technicians and the dealership have not been able to repair. An online search indicates this is a widespread issue and Gm has issued a bulletin. This needs to be a recall.

While being in a stationary position, my vehicle key will not come out of the ignition. If the key is inserted and immediately attempted to be removed, it will come out with no issues. However, if the key is inserted and the vehicle is driven, the key will be stuck in the accessory 'acc' position. The key will remain stuck for over 10-15 minutes until it can be removed from the ignition. (the longest wait time was 30 minutes) this issue has caused potential theft for our truck and threat to our own safety. It has also caused the vehicle battery to completely die, due to the keys being stuck in the acc position.

Several times in the past 2 years, my 2015 GMC Canyon has stalled when either coming to a stop or trying to start from a stop. Most times it shudders while stopping then the engine shuts down. 2 times I thought that I was safe from stall because it remained running after the shudder but when I stepped on the gas to go it stalled. The last time, about a week ago, it happened while trying to cross a busy intersection. Causing me to panic, throw it into neutral and start, with barely enough time to throw it into gear and get out of the way of oncoming traffic. It's scary and dangerous to both me and to other drivers. Ive attempted to take it to the dealer but they won't do anything because there aren't any warning lights on. I did get a notice on this, took it back into the dealer and again was told without warning lights they won't do anything. So does someone actually have to die or be in a life changing accident for something to be done?

Oil coolant line that is not viewable has rusted out and oil is leaking from my car, almost causing engine damage. I did not receive an oil low warning until I was out of oil. No indications the oil was leaking and even with consistent oil changes it was unable to be seen until there was a problem. I am unsure how long this has been happening since it was a slow leak and I didn't get any alerts until all my oil was gone. My truck is 4 yrs old, I bought it used September 29,2015 with 1100 miles on it, I maintain my vehicle, it has 43000 miles and I get ziebart rust proofing yearly, that I bought through the dealer when I bought my car. This should not have happened.

Fall of 2015 the heater and defrost system went out. Only cold air coming through. Entire dash board had to be removed. Vehicle in shop for over 1 week 349 days later in fall 2016 same problem. GM dealer states that the internal lever that closes the heater door broke. This occurs when vehicle is moving or stopped. Repair bill over $1,000. Vehicle still on warranty for 1,500 miles. Concern about long range reliability. One time problem but 2 times in less than a year. Windows fog up and can not see to drive.

The power steering on my 2015 GMC Canyon has failed repeatedly while driving in different road conditions. In one case, I was going straight on a surface street at low speed. However, in another I was cornering through a highway off-ramp at approximately 45 mph. When the power steering fails, there is a warning chime and the power steering and stability control warning lights activate simultaneously. It becomes extremely challenging to steer, and in the case of cornering at speed the vehicle pulls in the opposite direction of the turn [ie, it pulls towards danger]. pulling over and restarting the vehicle has 'solved' the problem each time, albeit temporarily. I took the vehicle to a GM dealer to get fixed, but they could not find any related mechanical issues or GM provided sw patches that would fix the problem. So the GM dealer had me leave without fixing any of the underlying conditions that caused the power steering failure. Needless to say, this is an extremely dangerous and apparently wide-spread issue based on the number of similar complaints I have read.

The transmission does not down shift when climbing a small hill in normal traffic at normal speeds. I constantly have to use the manual transmission to make the truck downshift or I have to press on the grass in order to bring the RPM up a little higher using more fuel than required. This in itself is dangerous since I am in then middle of traffic. When I purchased the truck none of the recall were on carafe nor did the dealer inform me that this vehicle type and model has already had several recalls affecting its performance and safety. There is also something wrong with the defrost system whether its on heat or cool. There is a rattling noise that can be heard over the fan noise when the vehicle air conditioner is switch to the defrost mode. I am truly disappointed and very concerned for my safety. GM should have pulled this vehicle off the market!

(3rd) - occurrence of the following same problem....the heater and defroster systems in my new 2015 GMC Canyon produce only cold air, regardless of the settings. This creates a fog film on the inside of the windshield making the Canyon inoperable due to lack of visibility. The GMC dealer has already replaced several "heater/defroster", but the new system continues to fail. The lack of heat problem occurs at all times (I.e. manual key start, remote start, cold engine start, warm engine start, etc.)
