B1A36 on Jeep
Manufacturer-Specific Body/Security System Code
B1A36 on Jeep vehicles indicates manufacturer-specific body/security system code. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. B1A36 is a manufacturer-specific body code that falls within the security-systems range and does not have a single standardized SAE definition. On vehicles that use this range (notably Chrysler/Stellantis and Mitsubishi) the B1A3x codes generally relate to immobilizer, key/transponder, or security-module communication faults. Without confirmation from make-specific service data the exact meaning cannot be stated. Have it read with a brand-specific scan tool to pin down the precise definition. Typical repair costs on Jeep range from $200 to $1,400, depending on the specific model and root cause.

- Power Liftgate Opens or Closes Erratically / Fails to Latch2022-2025
Owners have reported the hands-free/power liftgate on the WL Grand Cherokee opening unexpectedly, reversing while closing, beeping without completing the cycle, or failing to latch. Reports point to latch alignment issues, pinch-sensor calibration problems, weak struts, or software/body control faults. While not usually catastrophic, it is a recurring nuisance and can create injury risk or battery drain if the gate remains ajar.
