My Truck has less than 35,000 miles and I've had Transmission issues. I've taken it to the Dealership and they don't have an answer to the problem other than changing the transmission fluid as that has resolved issues on other trucks. When I took it in, I would shift it out of park to drive it jerks, when I shift from drive to reverse, it jerks, when I shift from reverse back to drive it jerks. When I'm slowing down at a stop sign or stop light it shifts weird. I've been getting on a busy highway and accelerated and it downshifted so hard and kind of stalled, I swear took it at least 5 seconds to catch up and gain speed. I don't want to be on the HWY and my truck stall because no one knows what's going on or how to fix it.

Noticeable ticking noise started coming form the engine, upon further inspection it was the lifters that was causing the noise. DFM, AFM the truck is out of warranty at 76,000 mi. So i got a second opinion from another shop and got it fixed through them, not the dealer. My shop re surfaced the Heads and went a few steps further than the dealer would have done.

Dashboard and display screen doesn't shut off when key had been removed from the ignition. Constant freezing, call dropping and sound boost at random moments. Ticking sound when barely touching the gas. Hard shifts. Bluetooth connects and disconnects constantly. If GM released a defective vehicle, in which they are aware of the problems should be fixed. Not only for me but for the tons of thousands filing known major problems as well.

My truck has a vibration when going down the highway at speeds of 70 mph. The dealer has done a transmission flush but still have the same issue. I am afraid that the driveshaft or the transmission may lock up while we are on the highway with the family.

Thousands of these vehicles have Engine Lifter failure problems at early mileage and if your vehicle is out of warranty you have to pay. These are vehicles with the AFM 5.3 and many are failing. This is a well known problem and should be recalled soon. If your engine fails on the highway it can be extremely dangerous.

The transmission will sometimes hesitate/lag for a few seconds when shifting from 1st gear to 2nd gear. This seems to occur only cold starts where the vehicle has sat for a long period, such as overnight. On the most recent occurrence, I was stopped at a stop sign on my road and began to turn left (northbound) on to the busy highway. While turning from the stop sign on to the highway, the vehicle vehicle hesitated mid-shift and I lost acceleration. After a few seconds, a loud clunk was then heard, the truck jerked - throwing me forward, and acceleration was restored. This delay resulted in a near-miss collision as there was an approaching vehicle headed southbound and I was stuck in their lane since my vehicle was not accelerating. Issue reported to Heartland Chevrolet (501 Rte 291, Liberty, MO 64068) to document and investigate the issue. Vehicle taken to dealer next day. After 3 days of service, the dealer service team could not reproduce the issue and escalated to regional GM engineer (Service Manager called him directly.). Engineer stated that hesitation is normal. Still an on-going issue; work around has been to let the vehicle idle longer before driving on a cold start. Sometimes you can "feel" the hesitation and know when to let off the gas pedal few a few seconds until the shift in to 2nd to avoid the vehicle throwing you forward, being able to have better "control" of the hesitation issue.

The "service brake system" and "service ESC" lights came on, along with the service engine light and rough idle, resisted roll (slight brake applied, perhaps?) and per the dealer, no code was stored and there is no fix. Bulletin pit5728B says different and not to drive the vehicle until fixed. I am refusing to accept my vehicle back until fixed as of 27 Apr 2021.

While driving to school which is approx 70 miles from my house, I was approx 10 miles from my end location and had been driving for 1 hour and 15 minutes without issues. I was driving on I-70 at 75 mph when the truck completely shut down. The engine shut off, brakes went out, steering locked, all electrical shut off. The truck was dead for approx 4 seconds when it kicked back on on its own. The truck continued down the road like nothing had happened. The truck did the same thing about 3 miles after the first time the truck died. There were no more incidents during that trip. Later that same day I was pulling into kroger parking lot turning into a parking spot at about 5 mph when the truck completely shut down again. The truck was dead for approx 3-5 seconds each time with completely shutdown before completely restarting on its own and continuing like nothing happened.
