Breakdown, stranded at rest stop on CA I5
While headed out of the SF Bay Area to southern WA state, had two warning lights suddenly illuminate - icons of a car with squiggly lines behind it (ESP, per manual) and a tire with up and down arrows on it (ASR/BAS per manual) Stopped, checked owner's manual - said "drive on with care. Consult a qualified workshop as soon as possible". Lights reset after a restart. Drove on.
Lights came back on, plus ABS icon, red brake system warning lamp, and check engine icon. Speedometer stopped registering (dropped to zero) and cruise control stopped working. Vehicle seemed to run fine. Again stopped as soon as safely possible. This time the manual said "Do not drive on. Consult a qualified specialist workshop." All lights except check engine icon would reset, but would come back on after a few minutes. Called two Freightliner shops and one Mercedes shop. One had no advice, the other two said try driving it - the lights might clear. One indicated may have been caused by a wind gust. Tried to drive on but the vehicle would not shift out of first gear - only got maybe a quarter mile, then backed back to the safety of the rest stop. Now awaiting a tow truck, with no hope of having the vehicle looked at before Monday.
Anyone experienced anything similar? Seems like an electrical or electronic issue to hit so many systems simultaneously (also what one of the Freightliner techs surmised). Looking for any advice!
