Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

For months my GMC Canyon will start first thing in the morning, I will drive up tp the first or second stop light and my truck will begin to shake and act like it will shut off. Sometime it will die other times it just shakes. I took it into the dealership and they could not resolve the issue. This usually occurs 2-3 times per week.

On cold starts, the engine will stall at first stop. Typically this is at the first stop light or stop sign in the morning on the way to work. This is beginning to happen several times a week. It also has happened after sitting for several hours. It only appears to happen when starting the truck after the engine has cooled. Prior to stalling, the engine will hesitate and the rpms drop until ultimately stalling. I have called the GMC number and have asked the dealership to check it out. It cannot be duplicated by them and they say GM has not issued a recall or bulletin to repair.

The truck chugs and hesitates randomly when a down shift is required. Generally this random hesitation is just annoying. At times the vehicle will not downshift for a considerable time. When making maneuvers in and around traffic the trucks poor shifting causes the truck to jerk and not accelerate. When the truck will eventually does down shift the gas pedal must be all the way at the floor and accelerates at full speed. Bulletin pip5342A supposedly addresses the concern but says it is normal. GM tells the dealer not to attempt to fix. I have had multiple times where this problem has put me at risk for an accident.

I purchased this truck 3 months ago and it had around 9000 miles on it at the time of the incident. I was driving at around 25 mph when I noticed smoke coming from under my hood. I pulled over, shut the engine off, and popped the hood. I opened the hood and noticed the engine was on fire. Opening the hood just enraged it more. I slammed the hood shut, and got to a safe distance and called 911. Within minutes the truck was engulfed in flames. After the fire was put out, the firemen said it appeared to have started in the vicinity of the alternator. The bracket was melted off and all that was left of the alternator was a basket of copper. Everything minus the bed was on fire.

I wanted to reach out to you on GMC's claim that their engine achieves 305 horsepower. While it may be true that their engine achieves this figure it does so at a stated 6800 RPM. The 6800 figure is important to note because the trucks" red line indicating potential dangerous operating conditions start at 6500 RPM. So in essence in order for an owner to achieve 305 hp they would have to be operating their truck in a potentially dangerous manner. Even in the 2015 Colorado owner?S manual it indicates the danger of operating above the redline? ?do not operate the engine with the RPM?S in the warning area.? GM is stating that someone can achieve maximum hp only by operating the vehicle in a dangerous manner....really"! I believe it will only be fair for GMC to re-evaluate their maximum horsepower prior to their engine hitting the redline.
