Repeated attempts by jones Chevy, sumter SC, they have not identified the vibration problems with my new vehicle. 22+ days in repair, multiple visits, and GM classifies harsh vibration as "normal characteristic" and closed the case, saying its final. I have contacted GM CEO with certified letter, discussed with exec. Customer support team, and posted on social media to find any solution. GM customer service is the worse I have ever experienced. So far dealer has conducted transmission drain and flush per a tsb, changed torque converter, evaluated vibration with pico scope, and problem still exists and persist. Now today it's back at dealer for a prop shaft swap, from a new truck. My vehicle now has 6K miles, and problem started at 5K after the drain and flush. GM says the vibration is normal because of the dfm, dynamic fuel mgmt. System. I say bs. They are wrong, and no vehicle should vibrate at low or high speed to the point you feel it through the seat, steering column, steering wheel and harmonic distortion in the cab. GM knows what the problem is, they just don't want to admit. Next step, arbritration" any feedback is much appreciated to solve this vibration issue. GM - do the right thing and issue a recall before someone gets hurt. Remember the ignition problem" this problem isn't going away.

The 8 speed transmission sometimes gets hung in between gears or shifts very hard after it intermittently comes out of gear. This week, I went to cross a road on dry road conditions and the vehicle came out of gear, the engine revved and I was without a gear for 2-3 seconds, causing the oncoming traffic to be uncomfortably close by the time I regained power and was able to cross the road. There have been other times that I have been at a stop sign and I go to take off and the engine revs up as I hit the gas but it is not in gear and then abruptly snaps into gear, causing the tires to actually squeal. So this issue has happened when the truck is still moving and also when it was at a stop sign and not in motion,

Ongoing communication between local dealer and Chevy/GM executive support team to fix shudder/vibration is not resolved. Chevy states "normal characteristic" for this model vehicle, 2019 Silverado 5.3, 8 speed. I vehemently disagree. GM approved torque converts swap and then problem got much worse. They now say, resolution is final, this in normal! pleaded with dealership general mgr, to contact district supervisors to re-evaluate. Now they are going to run pico test and comparative analysis against 2 new truck on their lot. My truck only has 6K miles and should shake and vibrate, but it does and getting worse. Harmonic distortion within cab getting worse. Seems the more miles I put on it, the worse it gets. After drain and flush of transmission, per tsb, now also had delayed shifting, and having to brake hard when downshifting because it wants to lurch forward. Frustrating at best, but safety and risk of injury are my immediate concern. Need help!

Was driving back home going around 65mph when all of the sudden it down shifted and eventually lose power. I pulled over restarted truck and check engine light turned on and would not shift out of first gear. I could not take it to the dealership that day as it was Sunday and would have to wait till Monday. Monday 10/14/19 came and I took it to the dealership. Dealership has still not fixed the problem, they have already replaced the pc module, and valve body. Now they are they saying they are going to replace the wiring harness on it. I do have a GM case #9-564919828, however they are no help and basically tell me the same thing as the dealership does. Truck has been at the dealership since 10/14/19 and have still not fixed it, todays day 12/05/19.

2019 Chevy Silverado, 5.3L with 8-speed transmission. Experienced intermittent transmission shudder at 32 - 44 mph. Vehicle serviced per GM ts bulletin to drain and flush transmission, replace defective fluid with atf mobile 1 synthetic. This was done twice and problem got worse. Now shudders constantly at 32-44 mph. Dealer was informed by GM tech that this is a normal characteristic for this model. I disagree! my brand new truck with only 5K miles should not be shuddering and shaking. Was told that the active fuel management system, 2 to 4 cylinder mode is suspect and affecting torque converter shudder. But this is normal" I have requested repair or replace or buy back and contacted GM corporate directly. GM senior advisor team has not yet contacted me. I have refused to drive it, and left it at the dealership until resolved. They gave me a loaner to drive in the meantime. Appears lots of instances on the internet of similar issues and owners are not happy. Why hasn't GM engineering fixed this problem or issued a recall yet" I am currently awaiting responses from GM / Chevy for resolution. This is unacceptable.

Automatic transmission and brake pressure problems. The automation transmission jerks when accelerating from zero miles per hour or at low speeds. It can dramatically increase the rate of an incident due to the powerful movement that the movement does to the whole truck. You can then feel the whole truck sway back and fourth due to the impact. This "jerking" from the start can increase the risk of hitting anything in front of you because of it not being controlled properly when moving in close proximity areas such as high volume traffic areas, high counts of pedestrians walking across the street, parallel parking, and parking close to another car in front of you or any other type of object in front of you. The brake applications take an extreme amount of pressure to stop the vehicle at all given times. My truck is brand new and purchased on 9/18/2019.

I originally bought a new 2019 Chevrolet Silverado 1500 ld on 06/08/2019, I really liked the truck and its many features. After several weeks I noticed the whole underside frame and driveline components were rusted and corroded. I brought it back to my dealer and they immediately located a replacement vehicle for me. I picked up the 2nd new truck on 07/10/2019. This truck has the same defects as the first vehicle. Chevrolet has an issue with this model truck. I spoke to GM and they didn't seem to care blaming the dealer for not inspecting truck properly. I am very disappointed and unsure where to turn next, can you help me?

Hard shifts. It felt like someone hit me. The truck slams into gears as you are driving. Also, after doing a 3 point turn. There was an approxamententaly 3 second lag before going into gear. It hit so hard that the truck shook. It felt like a collision. It has stumbled several times and made me doubt my ability to get out of the way of traffic.
