Digital Dashboard Malfunction
I have a new 2021 Allegro Red 33aa with digital dashboard. After driving about 2 hours at 70 MPH, the cruise control drops out and will not re-engage. After about another 10 minutes of driving, the check engine light comes on and ABS COMM FAIL displays. After another 10 minutes the dashboard goes “haywire.” The tach, speedometer, DEF gauge, temperature gauge, and oil pressure gauge all go to zero. Finally, a LOW VOLTAGE error appears (the spyder control reports normal voltage).
It’s been in the Freightliner shop 4 times for a total of 47 days. Each time I take it in they return it, but the malfunction repeats again after 2 hours of driving at 70 MPH.
Freightliner thinks it’s something to do with J1939 network or module. But they can’t find anything.
I’m close to hiring a consumer attorney to file suit to get Freightliner’s attention.
Any suggestions or thoughts?
