On the 2021-2024 Jeep Grand Cherokee L, the Grand Cherokee L's eTorque mild hybrid system experiences 48V battery faults and stop/start malfunctions. The auxiliary battery loses charge capacity, causing the stop/start system to disable itself and triggering warning messages. The belt-starter-generator can also produce vibration during engine restarts.

Common Symptoms

  • Stop/Start system disabled message
  • ESS unavailable warning
  • Rough engine restart at stop lights
  • 48V battery warning
  • Reduced fuel economy
  • Belt chirp on engine restart

How to Fix

A dealer software update recalibrates the battery management system. If the 48V battery has degraded, it must be replaced (dealer-only part). Ensure the 12V auxiliary battery is also in good condition as a weak 12V battery stresses the eTorque system.

Owner tips & cautions

  • TipKeep both the 48V and 12V batteries healthy — a weak 12V battery causes the eTorque system to overwork and fail prematurely

On the 2021-2024 Jeep Grand Cherokee L, wL Grand Cherokee L owners repeatedly report a flat 12V battery after the vehicle sits for as little as several days. The root cause is a module that never enters sleep mode after lock-up, so residual current draw stays far above the roughly 30 mA that should remain about 30 minutes after locking. Owners and dealers have traced multiple distinct causes: an active ground fault in the rear liftgate exterior lock switch that repeatedly cycles the door locks and exterior lights, the connected-services/telematics box waking the vehicle to answer server pings, and modules left awake by incompletely debugged control-unit software. Note this is separate from the 48V eTorque battery fault - here the conventional 12V starting battery goes dead.

Common Symptoms

  • Dead 12V battery after the vehicle sits several days to two weeks
  • Door locks cycling or exterior lights flashing on their own while parked
  • Multiple warning messages on the cluster after a jump start
  • Battery repeatedly replaced under warranty with no lasting fix
  • Slow crank or no crank

How to Fix

Have a technician perform a proper parasitic draw test: lock the vehicle, wait 30-45 minutes for all modules to time out, then measure current at the 12V battery; anything above about 30 mA needs to be traced by pulling fuses to isolate the circuit. The most commonly confirmed hardware fix on the WL is replacing the rear liftgate exterior lock/release switch (which requires liftgate trim disassembly). Also apply all outstanding module software updates through the dealer, and try disabling connected services or unpairing the Jeep app if the draw follows telematics. Replace the 12V battery afterwards if it has been deeply discharged repeatedly.

On the 2021-2025 Jeep Grand Cherokee L, the Grand Cherokee L with the dual-pane panoramic sunroof is prone to water leaks caused by clogged or kinked drain tubes. The extended-length L model has longer drain tube runs than the standard Grand Cherokee, increasing the likelihood of blockage. Water pools in the sunroof channel and overflows into the headliner, dripping onto the front seats, center console electronics, and overhead console modules. The rear drain tubes are especially prone to clogging where they pass through the C-pillar.

This issue also affects: Jeep Grand Wagoneer

Common Symptoms

  • Water dripping from headliner near sunroof area
  • Wet spots on front or rear seats after rain
  • Water stains on headliner fabric
  • Musty smell inside vehicle
  • Overhead console lights or controls malfunctioning

How to Fix

Clear all four sunroof drain tubes using compressed air blown from the top opening — do NOT use a wire, which can puncture the tubes. Check that the drain tube exits under the vehicle are clear of debris. If water has already entered the headliner, pull it back to dry the insulation and check for mold. Inspect the overhead console module and ambient lighting connectors for corrosion. Stellantis has issued a TSB with revised drain tube routing for 2021-2022 models.

On the 2021-2025 Jeep Grand Cherokee L, grand Cherokee L owners frequently see the adaptive cruise control and forward collision warning systems drop out with an "ACC/FCW Unavailable, Service Required" message, or find the FCW OFF telltale permanently illuminated and unclearable through the settings menu. The forward-facing radar sensor behind the lower grille is the usual culprit: it is low and exposed, so road debris impacts, a minor front-end bump, ice or heavy road grime knock it out of alignment or damage it outright. Related complaints include the system failing to warn or brake at all in owner-conducted tests, and conversely phantom auto-braking events during parking maneuvers and intersection turns. Compounding it, any front-end body or bumper work that disturbs the sensor requires an ADAS recalibration that many general shops skip.

Common Symptoms

  • "ACC/FCW Unavailable - Service Required" message
  • Forward Collision Warning OFF telltale stuck on
  • Adaptive cruise control will not engage
  • Automatic emergency braking activating with no obstacle present
  • Blind spot monitoring warning at the same time

How to Fix

Clean the lower grille radar area and the windshield camera first - grime and ice cause a large share of temporary faults. If the message persists, have the module scanned for radar-specific faults and check the sensor bracket for impact damage or misalignment. Some cases are corrected by a dealer software update plus a reset of the programmable feature configuration. Where the sensor is damaged it must be replaced and then professionally ADAS-calibrated - the calibration is mandatory, not optional, and a replacement sensor that is never calibrated will misjudge distance. Always require documented ADAS recalibration after any front bumper or windshield replacement.

Typical repair cost:$250 - $1,600
