I was driving and came to a stop at a red light. When accelerating on green the transmission would not go into gear, stalling my vehicle. Nearly causing the vehicle behind me to rear end me. The vehicle eventually went into gear and started to slowly accelerate with shuttering of the transmission.

- Tucson , AZ, USA

When accelerating the transmission shakes violently under the hood. It shakes so bad that other vehicles can hear it the vibration is intense until you take your foot off the gas and then try to accelerate again it happens a few times then it-??ll stop until the next red light. Slowly accelerating makes it worse but doesn-??t matter either way.

When a Check engine light is on it's for a low voltage on the charge air coolant sensor, took to the chevy dealer, they replaced a connector to the sensor, at a cost of $600 never got off lot, light returned, they then said I need a new engine wiring harness at a cost of $100, the dealership said this is a problem with these trucks and GM knows about it but won't recall them. Now I'm struck with a 5-year-old truck that I can't use, When this light is on, I also receive an Emission system warning, and the truck deregulates and goes in limp mode. as speed is reduced it becomes dangerous to drive in traffic, as GM knows about this, they should recall these trucks and fix the problem, they even say it's because cutting corners on the wiring harness cover causes this problem. as a senior living on a fixed income there's no way my wife or I can get this repaired, so were forced to drive it in limp mode until it dies on us, hopefully not in heavy traffic.

I am writing to formally lodge a complaint regarding my Chevy vehicle, which is experiencing significant engine issues. The motor is knocking, and the check engine light has illuminated with trouble codes P0011 and P0016. These codes indicate problems with the camshaft and crankshaft timing on Bank 1 (driver's side in a V6/V8 engine). Specifically, P0011 signifies that the camshaft timing is over-advanced, while P0016 points to a correlation issue between the camshaft and crankshaft positions. These issues are often related to the Variable Valve Timing (VVT) system and may be caused by faulty camshaft or crankshaft sensors, timing chain problems, or solenoid issues. This situation directly correlates with a recent recall affecting similar VIN numbers for 2021-2024 models with similar engines. An independent service has confirmed that my truck requires a new engine, which aligns with the issues addressed in the aforementioned recall. I urge the NHTSA to investigate this matter further and consider extending the recall to include my vehicle, as the problems I am experiencing are consistent with those covered by the recall.

I had the same transmission torque converter failure shuddering jerking as the class action lawsuit as the 2015-2019 8spd that are covered but 2020 is not..it is a known issue. I had a transmission repair shop replace torque converter and service transmission to repair transmission issue. I did not have any warning or check engine light

This transmission has shifted terribly since day 1. It currently has 114,000 miles. It would slip gears going up an incline. I was told the fluid was too slick. Fluid change at 30k. Started to stumble on downshift again. Fluid / filter change done. Brass, metal in filter/ pan. It will downshift so hard that it feels like you are getting rear ended at a stop light. 1-2 seconds after a complete stop, bam. Been down 9 weeks.

- Fairbanks , AK, USA

A few month ago this 2020 Silverado check engine came on in the middle of driving. It stopped shifting and almost caused an accident because it wouldn-??t stop. I took it to the dealer and they found nothing wrong. Today, it is doing the same thing with faulty shifting, especially during first and second gears and when I initially accelerate. It is jumpy and worried and accident will happen if the car stops shifting like before. The check engine light is on again

- Upland, CA, USA

Transmission shudders started around 65k miles. Shop said it was recommended to do a transmission flush. We did that. Now at 72000 miles the transmission is locking up. It has been inspected by a reputable auto shop and they stated it needs a new transmission. The engine light came on when this issue happened. I was in the middle of traffic at a stop and when I started going it stopped abruptly and threw me forward. It was so violent that I thought I was rear ended. It did it two more times.

2020 Chevrolet Silverado with 72K miles has a bad Transmission Torque Converter. Warranty expired 2 months ago and will have to be replaced in the next 30 days. Had the truck checked out at a local transmission shop that said this is happening on every v6 Silverado that is being brought in.

The transmission has been slipping and shuttering which shouldn-??t be an issue at 119,000 miles. This opposed a huge safety risk for me and my girlfriend on the highway. I was driving and it shuttered so bad i had thought the wheel was loose and coming off. I had to pull over on the highway to check the lugs and came to find out it-??s the transmission, because it shuttered numerous times after. On top of that the entire trip was the transmission shuddering slightly making the wheels cut the the left and right. But throughout the trip, it had a slight shutter the entire time and a couple of big shutters, and one very large shutter that had my girlfriend think I ran over a bunch of wood in the road resulting in me pulling over being in danger and possibly wrecking from the shaking, and having to exit my truck on the side of the highway with 18 wheelers and other vehicles flying at 80+ miles an hour. Besides the safety issue, there should be no reason for these transmission going out like this at 60k miles and 100k miles it-??s extremely cheap of GM and a huge hazard to many families.

Transmission is changing out very hard in each gear. On tonight while I was driving, I lost speed on the interstate and when I push the accelerator, It was like back wheels were locked up. I left it at the next exit gas station and came back and towed it home. Lucky I was able to put hazard lights on and get off the side of the road but it was very slow speed. Yes I have had it look at certified dealer under Cheverolet. It was no warning light. I was going 65 and in a split second the rpm went up high and I was doing like 25. Once I finally made it to the gas station and got out the truck smell like a burning smell

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated after an independent mechanic had performed an oil change on the vehicle, the vehicle was moved and parked.

My truck rpm goes idle while driving also a loud knocking sound when accelerating

- Mesquite, TX, USA

The vehicle was being used in a normal daily driving routine. I was stopped(fortunately) at a traffic light. The light turned green and I went to proceed and began to press the gas pedal and the engine made a loud pop noise and began to barely stay running. I brought the vehicle to the shop(GM dealership) for diagnosis and repair. The motor had to be rebuilt new camshaft, lifters, etc. The vehicle is also having transmission issues, heavy vibration, hard shifts and constant fluctuations in the rpms while maintaining a set speed. The transmission issue still has not been resolved.
