2016 GMC Canyon

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.

On [XXX] at approximately 5:30p, I was driving normal highway speed when I saw what I thought was exhaust trailing behind. There were NO dash warning lights, engine temperature showing normal range, car was performing normally. I pulled over to shoulder, turned off car, released the hood latch. My husband tried to open hood but it was too hot. We then realized it was smoke coming from under hood, not exhaust. Smoke began to come inside car through vents. I quickly exited the car, and within a minute the entire front end engine area was engulfed in flames. 911 was called, fire, police, highway patrol responded. Fortunately there was no injury to myself or husband. There was also concern of starting a brushfire risk here in SoCal, but it was all extinguished thoroughly. Truck was towed to Al’s Towing, 475 W Vermont Ave, Escondido CA 92025, ph 760-745-5933. A report has been filed with our insurance USAA, inspection by adjuster is pending. I also notified Temecula GMC, where I purchased vehicle from, of the incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Purchased this vehicle brand new and paid extra for Nav and a backup camera as I am a disabled Veteran! Currently have 32000 miles or so as i don't drive that much. No other lights or warnings came up before the following happened. Recently the radio stopped playing and the infotainment system went blank. It occasionally pops up a screen that says waiting on update, other than that it stays blank most of the time. The backup camera comes on intermittently but not always when backing up, maybe 1 out of every 5 times. Also the bluetooth went dead since this all started. As a disabled Vet I depend on the backup camera and built in Navigation so this is an issue! Called the dealer and 3 other radio and entertainment car stores and they stated this is a know issue and would cost around $1000 to $1200 to replace the HMI 2.5 module behind the dash which is the known issue. Looking online this is a well known and common issue and GMC has bulletins to diagnose but no free or discounted replacement or repair, even though it's all over the internet that GMC and Chevy Infotainment centers have issues. There is a class action lawsuit going on due to this issue as well. I'm sure there are others that just haven't complained and should be fixed by the dealer.

DEF Fluid/nox sensor. My truck has 37,000 miles on it. I have been limited to 65mph, 55mph, and then 5mph 3 separate times already because DEF fluid quality poor permanent code. It all comes down to a dirty nox sensor #2 in the exhaust. The DEF fluid is not actually poor quality. I frequently travel long distance. This permanent code should not be limiting my speed. I want a full recall and have this removed from the truck. I did not buy a truck for it to tell me I can't go a certain distance for so many miles because it may be polluting a little extra. This is a safety hazard and a costly hazard when you get stranded on the side of a highway or cannot keep up with traffic because the truck is limited to a certain speed. The message also blocks all digital functions from being accessed at all times.

Ignition key randomly will not release from ignition switch. The key is stuck in the ignition in the accessory position which in turn kills the battery. Unable to remove key! I have read this is a common problem with my vehicle year / model. When placing vehicle in PARK it is not reliably returning the confirmation to the solenoid lock on the ignition switch that the transmission is in PARK. My dealer finally admitted this is a common problem. GM needs to take responsibility and activate a recall.
