Fuse and Relay Center issue
I'm having an issue with my '19 ZL1 1LE and I'd appreciate any input.
At about 900 miles, it started badly misfiring. It would barely run and I was lucky it made it to the dealership. The car would die at idle and had no acceleration; it ran very rough.
After about a week evaluating it, the dealer told me the "Fuse and Relay Center" (part #84572691) required replacement under warranty. Apparently this issue was causing the car to run on half of the cylinders, but they had no explanation why this occurred.
FWIW, the tech comments state "ubec internal connection failure" & "found codes on current p135B 00 bank 2 ignition coil voltage supply".
It ran fine for about a month, and the issue arose again yesterday. I am bringing it back into the dealer tomorrow.
Has anyone heard of such an issue and have any suggestions?
Thanks in advance,
Mike
