What Tends to Fail First on the 2021 RAM ProMaster
The systems that tend to fail first on the 2021 RAM ProMaster, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The Uconnect infotainment system can freeze or reboot, and reports of parasitic battery drain are common, often due to software glitches or various sensor faults that remain active.
