Vehicle reduced power and displayed many errors on the dashboard, including reduced function of forward collision avoidance, reduced acceleration, ESC SES TC. A vibration/rumble was observed (unsure if it was steering assist or propulsion surging), as well as increased engine speed without vehicle acceleration and no engine speed increase while pressing the accelerator. Turns seemed to make the symptoms worse and cycling power on the truck would temporarily clear the faults. Root cause was determined to be TSB 21-NA-149 Cause 3 and diagnosis and repairs took more than a week.

Driving vehicle from work to home when the vehicle started to stutter and immediately shut down with no power or any capability to turn the vehicle off of the road. This shutdown immediately caused blockage of a major road; since the vehicle could not be moved due to no power to steering wheel nor ability to place the vehicle into neutral. Determination was that the fuel module went bad. No warning of failure of component was indicated by check engine light until after the incident happened. Luckily this shut down of all components of the vehicle did not occur on a high speed road since I did not have any control of the vehicle after the fuel module failed.

Vehicle was driven into parking lot and was idling. Without warning, it began misfiring and stalled. Vehicle would not restart and was towed to the nearest dealer. The diagnosis was a fuel pump driver module that had internally shorted. Thankfully, it failed in the parking lot. We had recently arrived at this location for the winter having driven the vehicle approximately 1500 miles over 4 days. We were lucky the failure did not occur on the highway as the unexpected stalling would potentially be a significant safety concern. Please note that this vehicle is a 2022 Chevrolet Tahoe. The 2021 Tahoe was under a recall for this same issue (see recall N212332040). The dealer said that this is a common problem with these vehicles. Perhaps the recall needs to be expanded.
