The vacuum pump failed resulting in loss of braking assistance. Mushy and hard peddle. Very noticeable at low speeds. Mine went out while exiting the highway at highway speeds. Causing excessive speed on the off ramp and inability to safely brake. Appears to have been a recall for my year vehicle. After calling the dealer I was told M VIN was excluded from the recall.

Brake power failure, where as the brake became stiff and it was hard to bring the truck to a complete stop. The truck was moving less then 10mph and had a utility trailer on the hitch. The truck was on residential road. This happened twice more for a total of three failures under similar circumstances. Moving under 10 mph on surface streets and having a camper trailer on the hitch of the truck.

The electrical issue is sometimes the truck will just stop basically there won't be any power whatsoever, everything just shuts down and will not start, we were on tiny town road when it happened and on fort campbell blvd, we had to have someone come with jumper cables and help me start the truck it has done that at least 3 times. When we took it in they said they could T find anything. Also since I got it I have had nothing but issues. The brakes and rotors have been replaced on this vehicle at least 4 to 5 times, when we would take it on the interstate it would shake when we would put the brakes on and so we took it in more than once to fix it. Also there is something to do with the theft deterrent system as well. It just seems there is always an issue and I'm so tired of this truck.

While driving home, a stabilitrak warning appeared on the dash and my ac/radio began to stop but ramped back up after the dismissal. Once I got to my street, I made a left and the truck completed turned off. My steering wheel locked up, the wheel locked up, and there was no power to the vehicle. After about 3 minutes, the vehicle lights turned on and I was able to get to my driveway. I cannot imagine what would have happened if I was on the freeway. There's many other people on the web that have had the same issue with this truck.

Having major complications with steering while backing up, loss or power steering and brake system not working accurately

- Wylie, TX, USA

While backing the camper into a camp site with a slight upgrade, when I moving forward to straighten the truck, the brak pedal became hard to push down. Each time I pressed the brakes, it became harder to press, and I felt a pulsing sensation pushing back up on the pedal. After several tries, it became impossible to push down on the pedal. I was moving under 1 mph at the time with nothing in my way. After backing up again, I tried it again with the same results. This truck was taken to a dealer previously for the recall listed for braking booster that required recalibrating the electronic brake control module. I believe the service either didn't work, or it created a new problem. The weather was clear, warm, and everything was dry. I have never had any other braking problems.

Recall number N192217410 and local dealer wont service. Saying it must be taken to Canada to be serviced. Service brake assist error on dic. Why send recall notice if country of use is not authorizing the recall. Is it only dangerous in certain countries?

- Hickman, NE, USA

While driving in reverse and in drive at low speeds, brakes failed to engage properly. At first I was trying to stop while in reverse to go forward. I had to press the brake extremely hard to vehicle to come to a stop. When I went forward, I experienced the same thing. Brakes did not engage properly and were extremely hard to press down to get the vehicle to stop. I stopped driving at that point because I was in a tight parking lot and didnt feel I could slow quick enough to not run into other vehicles.

There is an unintended braking during drive started to happened. Usually happens in auto and 4WD mode. The truck was in the middle of freeway of around 70 to 80 miles per hour and suddenly brakes jammed by itself. This happened more than 5 times. Checked the VIN first time through NHTSA website for VIN recall and shows 2 recalls. First one for ebcm reprogramming and second one for equipment vacuum pump replacement. Bring it to chevorlet of folsom, ca and they did reprogramming without the part replacement and told that truck is running fine. But the issue still persists. Now bring it to them and they said we dont deal with salvage titles. And just for my sake checked again for recall on NHTSA website and it shows none or might be they reported it fixed. But the issue is still there.

It started with the truck losing power when making slow speed turns into driveway/parking spot which includes loss of power steering which has caused me to almost crash several times. The power used to come back up but now it is resulting in the truck just turning itself off mid turn and not just on slow turns. It happened when I was making a turn onto a street and I was forced to muscle the truck off the side of the road- no power at all so no power steering-going about 10-15 mph. When driving with cruise control on if you use the turn signal it kicks off the cruise control. The ac will just stop and the truck will just shut off. The whole time all/any of this is happening my dash is telling me stability control is off, steering assist of off drive with care....if the dash has any power that is. The trailer brake system flashes like I am using the brakes when I am sitting in the truck door open, key out. I have unplugged that thinking it was the problem but it didn't change anything. At times it is completely random that all power almost bottoms out and comes back moments later. There is definitely something wrong and as see I am not the only one having these same issues...should investigate and offer recall and get these trucks fixed before someone does crash. My truck only has 53,300 miles on it and it has a new battery and we have checked the alternator. The date below would be when I almost crashed turning the corner and truck died.
