FUEL/PROPULSION SYSTEM
Potential Consequences:
I am reporting an issue with a 2020 Chevrolet Silverado 1500 equipped with the 3.0L Duramax diesel engine. The vehicle experienced a failure of the NOx Sensor Position 2, which significantly impacted performance and emissions compliance. GM previously issued Emission Recall N212351211 (March 7, 2023) for other diesel Silverado models regarding improper ECM detection of NOx sensor faults. The issue in my vehicle appears functionally identical, yet this engine and model were not included in that recall. The sensor was replaced and reprogrammed at a Chevrolet dealership at the owner's expense. After contacting Chevrolet, a customer retention check was provided, covering roughly half of the total cost. While appreciated, the remaining cost burden remains significant. If this model is eventually included in the recall, it may allow for full reimbursement and support for other affected owners. Online forums show that many 3.0L Duramax owners are experiencing similar failures, suggesting this may be a widespread and systemic defect. Due to the strong similarities with the recalled condition in other models, I respectfully request that NHTSA investigate whether this recall should be expanded to cover additional affected vehicles. This issue presents both reliability and emissions compliance concerns. In addition, the vehicle developed a separate mechanical/electrical problem shortly after the NOx sensor failure. Because it involves different systems, I will file a separate complaint regarding that issue.

Defect Description:
ELECTRICAL SYSTEM
Potential Consequences:
I’m reporting a safety concern involving a 2020 Chevrolet Silverado 1500 with the 3.0L Duramax diesel engine. The vehicle went into limp mode and died on the side of the road. AAA installed a new battery, which temporarily restored operation, though the “Service Charging System” warning remained. I drove it home, let it sit for several days, and then took it to a Chevrolet dealership. Although the warning light had cleared, I brought it in out of caution. The first dealer diagnosed a failed alternator and recommended replacement at a cost of $2,158.75. I was also told the vehicle was not included in any active recalls related to this issue. Believing the price was high and wanting a second opinion, I went to another Chevrolet dealer. They ran the same diagnostic and found no issue with the alternator or generator, charging only a diagnostic fee. They also said if the alternator had needed replacement, the cost would have been around $1,300. I mentioned to both dealers that I had seen similar alternator/charging system failures recalled on other 2020 Silverado models. Online forums and customer complaints suggest that many Silverado 1500 trucks with the 3.0L Duramax are experiencing similar problems, indicating a potentially broader issue. Given the inconsistency in diagnostics, the significant cost discrepancy, and the number of similar consumer reports, I believe this issue may be more widespread than current recalls reflect. I respectfully request that NHTSA investigate whether the existing recall should be expanded or if a new recall should be issued for 2020 Silverado 1500 models equipped with the 3.0L Duramax. This issue occurred shortly after a separate failure related to the NOx sensor, which I am submitting under a separate complaint.

I respectfully request that NHTSA investigate whether the existing recall should be expanded or if a new recall should be issued for 2020 Silverado 1500 models equipped with the 3.0L Duramax. This issue occurred shortly after a separate failure related to the NOx sensor, which I am submitting under a separate complaint.
Additional Notes:
I’m reporting a safety concern involving a 2020 Chevrolet Silverado 1500 with the 3.0L Duramax diesel engine. The vehicle went into limp mode and died on the side of the road. AAA installed a new battery, which temporarily restored operation, though the “Service Charging System” warning remained. I drove it home, let it sit for several days, and then took it to a Chevrolet dealership. Although the warning light had cleared, I brought it in out of caution. The first dealer diagnosed a failed alternator and recommended replacement at a cost of $2,158.75. I was also told the vehicle was not included in any active recalls related to this issue. Believing the price was high and wanting a second opinion, I went to another Chevrolet dealer. They ran the same diagnostic and found no issue with the alternator or generator, charging only a diagnostic fee. They also said if the alternator had needed replacement, the cost would have been around $1,300. I mentioned to both dealers that I had seen similar alternator/charging system failures recalled on other 2020 Silverado models.

Potential Consequences:
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

ENGINE
Potential Consequences:
I am reporting an issue with a 2020 Chevrolet Silverado 1500 equipped with the 3.0L Duramax diesel engine. The vehicle experienced a failure of the NOx Sensor Position 2, which significantly impacted performance and emissions compliance. GM previously issued Emission Recall N212351211 (March 7, 2023) for other diesel Silverado models regarding improper ECM detection of NOx sensor faults. The issue in my vehicle appears functionally identical, yet this engine and model were not included in that recall. The sensor was replaced and reprogrammed at a Chevrolet dealership at the owner’s expense. After contacting Chevrolet, a customer retention check was provided, covering roughly half of the total cost. While appreciated, the remaining cost burden remains significant. If this model is eventually included in the recall, it may allow for full reimbursement and support for other affected owners. Online forums show that many 3.0L Duramax owners are experiencing similar failures, suggesting this may be a widespread and systemic defect. Due to the strong similarities with the recalled condition in other models, I respectfully request that NHTSA investigate whether this recall should be expanded to cover additional affected vehicles. This issue presents both reliability and emissions compliance concerns. In addition, the vehicle developed a separate mechanical/electrical problem shortly after the NOx sensor failure. Because it involves different systems, I will file a separate complaint regarding that issue.

If this model is eventually included in the recall, it may allow for full reimbursement and support for other affected owners. Online forums show that many 3.0L Duramax owners are experiencing similar failures, suggesting this may be a widespread and systemic defect. Due to the strong similarities with the recalled condition in other models, I respectfully request that NHTSA investigate whether this recall should be expanded to cover additional affected vehicles. This issue presents both reliability and emissions compliance concerns. In addition, the vehicle developed a separate mechanical/electrical problem shortly after the NOx sensor failure. Because it involves different systems, I will file a separate complaint regarding that issue.
