Check Engine Light On problems of the 2020 Chevrolet Silverado 1500

This truck is 2 months old and only has 2300 miles on it. On Sunday 12/27, the truck would not start. All dash panel and light indicator warnings came on including 4 wheel drive assist failure, brake system failure, tps failure, check engine, battery error, etc. After jump starting the battery, the truck turned on but the check engine light stayed on all day. On Monday 12/28, the truck did not start again however, this time, no indicator lights, dash panel or anything came on and I was also unable to even lock the truck. It was towed to the dealership and after 2 days they still have not found the problem with the truck although they have indicated there is a clear problem. The truck is still currently at the dealership.

The truck is new with 700 miles. September 26th 2020 I came to a stop at a light. As I took off the truck started to jerk and the check engine light came on. I immediately drove it home. As I was driving home while in motion the truck would jerk when it was changing gears. I received a text from gm that said to have the engine or transmission serviced within 7 days. I did not drive it until I was able to take it to chevy. September 28th 2020 on the way there the vehicle did the same thing. On September 30th 2020 the chevy technician said the truck was ready he said the problem was a transmission control module that was not placed correctly. I picked the truck up October 1st 2020 and drove it straight home just fine. October 2nd in the morning driving to work the truck started to jerk again and the check engine light came on and I received another text from gm saying to have the engine or transmission serviced within 7 days. On the way to chevy I had to stop at a light when the light changed green the truck did not want to take off and started to roll back and I almost hit a vehicle. I put the truck in park turned it off restarted it then safely drove it to chevy. Today is October 4th and I haven't heard anything from chevy I did not believe that a transmission control module would be placed incorrectly from the factory I believe this truck has some kind of defect and is unsafe to drive until chevy figures out the problem.

Tl the contact owns a 2020 Chevrolet Silverado 1500. The contact stated that the key ceased in the ignition and the vehicle would not start. Several unknown warning lights illuminated including the check engine warning light. The contact stated that several unknown dealers were contacted by phone. The contact stated that an independent mechanic was able to get the vehicle started however, the check engine warning light was again illuminated. The contact stated that the vehicle had been taken five times to several unknown dealers with the purge valve being replaced three times. The vehicle was taken to jim browne Chevrolet Buick GMC of dade city (10741 u s 301, dade city, FL 33525, (352) 567-1222) and remained at the dealer while the mechanics attempted to duplicate the failure by driving the vehicle over several days and several miles. The manufacturer was contacted and informed of the failure. The contact was referred to the dealer and provided a case number. The contact was also provided a case number. The failure mileage was 13,900.

At cold start up, the truck immediately illuminated the check engine light with a message of reduced engine power. A shut down and restart produced the same results. Shut the truck off and pulled the trouble code p26bb. Next start up, check engine light was still on, but the reduced engine power message was gone. Drove it to the dealer with no problems, where they diagnosed a faulty coolant flow valve. 38 days later it still sits at the dealer still not repaired. If this problem was to happen unexpectedly while driving, reduced engine power could produce dangerous conditions in certain situations ( ie pulling into traffic, merging).

I was driving down the road, gave it gas to go around a vehicle and it felt like the vehicle shut down. Esc caution, check engine light, and brake warning/caution all illuminated. Vehicle began to slow down drastically and if I hadn't gotten off the road quickly I would have been hit. If I had been turning into traffic from a stop and that happened I would have been hit. Pulled the vehicle over, turned it completely off, removed the key, restarted the vehicle and everything went away except the check engine light. Headed to the dealership and again I gave it some gas and it did it again. Pulled over, turned off/on and same results, everything cleared but check engine light. If this were to happen on the interstate this could cause a major incident. I was on a city street on both occasions. I had to nurse the gas pedal returning to the dealership which was about 7 miles from the initial incident. The vehicle is a 2020 chevy Silverado 1500 with the 2. 7l turbo engine.
