What owners say
Driving on interstate sudden acceleration then when truck turned off radiator fans would not shut off ,also problems with infotainment system since truck was bought never fixed they always told me couldn’t duplicate problem
The truck has a hard downshift and when stopping and starting again at a stop sign it will lunge forward sometimes.Also,when holding speed at 50-60 mph you can feel a slight shutter like the truck is not running correctly.The dealer flushed the transmission when I purchased the truck but the issue continued so I made an appointment with the service department on march 3,2023.They took the truck on a road test and did notice the hard downshift and noted that this is a normal characteristic of this transmission(this is not normal and is unsafe)and will not offer to repair it.It is now the end of July 2023 and the issue continues and no one seems to want to do anything about it.I am going to take it back again but I am probably going to get the same answer
The transmission surges causing the truck to lunge forward when starting from a stop. The key will not turn completely off allowing the key to be removed. Both events occur occasionally so if the dealer says it did not happen to them then there is nothing they can do. Both things are being reported on the internet by numerous people. Both things are safety hazards.
The vehicle was going down hill on a very busy highway when we tapped the brakes to slow down and the brakes went to the floor and we skid about 300 yards before being able to get the truck to come to a stop. We kept tapping brakes trying to get them to grab and stop us luckily, the car a head of us turned right at the light so we did not crash into them. Then when it did stop the RPM started reeving up and the truck lunged forward then the RPM went down. We were very lucky we did not go through the intersection and wreck.
