This problem may be covered under warranty. Ask your Chevrolet dealer.
Camshaft Positioning Sensor for the second time, (code P0341). It seems that a good number of Duramax 3.0L that was installed in the 2020 and 2021 Chevrolet vehicles are having this issue. Some are not starting at all.
On my vehicle, I am getting poor fuel consumption, it went from 24 city and 30 highway to 18 & 19 respectively.
Definitely a pain in the arse and Chevrolet, as far I have searched, do not have a solution yet.

Camshaft Positioning Sensor, (code P0341).
Although the vehicle was repaired under warranty, it is still an annoying and PIA issue, due to not being able to use the vehicle in fear of being stranded on the road or causing a server damage to the engine (as the camshaft reluctor wheel could be bent).

Within the first 300 miles of driving this truck the engine light came on. Took it to the dealer right away and was told the pig tail connecting to the Knock Sensor was crimped. Parts ordered and I was told I would be contacted when parts came in to schedule service to repair problem. I was told to continue to drive truck and that the engine was okay.

Purchased NEW June 2020. Brought into dealership 4 times for engine light comes on. Other lights on dash board light up as well. One event, the driving system shut down while on freeway. They first thought it was the hyper link module for the lift kit.
Today, the dealer put in the 2nd new module and they drove the truck over some bumps and lights came on again. When you hit a "good" bump, makes the engine light comes on. Do not know what the problem is. The dealer is still researching the issue.
