I just returned from a family vacation that my wife and I took. We drove the 2014 E350 from Birmingham, AL to Flint, Mi, and back. The problem started a few hours into the drive. First, we would get the Blind Spot Assist Inop error message and then later the turn signals would quit working. When we turned the engine off and back on, everything would work again.

I disabled the Blind Spot assist thinking that might help the turn signal issue, but it did not.

Any ideas?

Thanks,
Mark

​​​​​​Mark, glad your plans did not get scrambled by this genuine issue.

This shares the same cause as the battery yoyo: silently soft-crashed CAN networking courtesy of CGW.


> SIMPLE WORK AROUNDS:
-- Drive with HEADLIGHTS:ON
-- Chassis REBOOT twice a month.

Fix being to resolder defective networking modules to preserve CGW integrity.

Please scan your car for faults so we can see consequences with a silent cause.
