Twenty-one owners describe a pattern of serious electrical and propulsion faults in the 2025 Grand Cherokee—most within the first few months of ownership. The most dangerous issue is sudden loss of engine power while driving, often at highway speeds (65–70 mph). Several owners report the vehicle shifting itself to park or neutral, becoming unresponsive to driver input, and stopping abruptly in traffic with no warning. One owner was rear-ended after the vehicle lost power and locked in park on the freeway; another sat stranded in a Florida intersection for 45 minutes during rush hour with a young child in the car and a heat index over 100 degrees.
Battery failures are widespread—multiple owners report complete battery drain within 3,000 miles and inability to start the vehicle. The 4xe hybrid models face a compounding problem: a high-voltage battery fire risk recall (68C) issued in October 2025 with no available repair as of December. Interim guidance tells owners not to charge the vehicle and to park it away from structures and other vehicles—rendering normal ownership impossible.
Dealerships consistently report they cannot find diagnostic codes or duplicate problems on their scanners, yet owners experience repeated failures requiring multiple service visits and 7–12 day shop stays. Several repairs involve replacement of start/stop batteries, transmission components, and hybrid control modules, but failures recur. The 4xe's transition from EV to engine operation often stalls or fails entirely. Owners also report limp mode, inappropriate autonomous braking alerts with no obstruction, and shifter malfunctions locking the transmission in park while driving.
Failure modes owners describe
Loss of Propulsion / Engine Stall While Driving
Complete loss of engine power or unexpected engine shutoff during operation, sometimes at highway speeds. Vehicle loses acceleration and comes to an abrupt halt with no warning. Some owners report the vehicle shifts itself to park or neutral involuntarily.
When: Occurring within first year of ownership; some reports at highway speeds (65–70 mph); at least one incident within 3 weeks of purchase; one at 5,000 miles; another at 12,000 miles
Symptoms owners cite: Complete loss of power while driving; Engine stalls with no warning; Vehicle unable to accelerate; Vehicle shifts to park or neutral on its own; Dashboard goes dark (all electronics unresponsive); Engine light and battery light illuminated; Inability to shift gears; Message center displays 'how to start the vehicle' instruction despite vehicle already running
Codes mentioned: AEBS alert, Engine light, Battery light
Repairs/costs cited: Dealerships cannot duplicate problem on scanner; no codes recorded. One owner reports replacement of transmission pump at 12,000 miles. Multiple owners stranded for extended periods (40+ minutes in traffic; 45 minutes at intersection).
Recalls/TSBs owners mention: NHTSA Recall 25V741 (Electrical System); no remedy available; dealerships unable to repair. One owner reports temporary repair by dealership. Another reports module replacement for 'Stop Propulsion' recall. Interim guidance advises owners not to recharge vehicle; park away from structures or other vehicles.
Battery Drain / Complete Battery Failure
Unexpected battery discharge or complete battery failure occurring within first few thousand miles, rendering vehicle inoperable without warning. Dual battery systems (start/stop and high-voltage) affected.
When: Within first 3,000 miles of ownership; one incident after 10 days of airport parking; another after 2 weeks of airport parking in December
Symptoms owners cite: Complete battery failure within first 3,000 miles; Vehicle will not start; All functionality shut down while driving or at rest; Accessory battery total drain after extended parking
Repairs/costs cited: Start/stop battery replaced after failing bench test. High-voltage battery monitoring required per recall; charging time degraded post-recall (10+ hours instead of 2.5 hours). One owner reports three separate instances across three different Jeep vehicles (2022, 2024, 2025).
Recalls/TSBs owners mention: Accessory battery replaced under warranty. High-voltage battery fire risk recall 68C issued; advises owners to refrain from recharging and park away from structures and vehicles. No timeline for remedy available.
Hybrid Battery / High-Voltage Battery Fire Risk (Recall 68C)
High-voltage battery poses fire risk even when vehicle is parked and turned off. Recall 68C issued for 2021–2026 Wrangler and Grand Cherokee 4xe but no remedy currently available. Owners advised to restrict charging and parking location indefinitely.
When: Covers 2025 4xe models; recall issued in late October 2025 with no remedy as of December 2025; affects vehicles in active use and under lease
Symptoms owners cite: Battery fire risk potential; Charging function affected post-recall; Slow charging times; Owners unable to charge vehicle safely or park near structures
Codes mentioned: NHTSA Campaign 25V74J, Chrysler recall 68C
Repairs/costs cited: No remedy available. One owner reports charging time degraded from 2.5 hours to 10+ hours after recall work. Dealerships cannot service vehicles with unresolved recalls.
Recalls/TSBs owners mention: Recall 68C issued; interim guidance states vehicle fire risk reduced when battery depleted. Owners advised to refrain from recharging and park away from structures and other vehicles. No remedy or timeline provided as of latest reports.
Transmission / Shift Control Failure
Vehicle unable to shift gears or shift control malfunction. Shifter may blink or demand operator shift to park and back to desired gear. Transmission control unresponsive during electrical failures.
When: First year of ownership; one incident within weeks of purchase; occurring while driving and at rest
Symptoms owners cite: Unable to shift vehicle into neutral or desired gear; Shifter blinking and demanding shift to park; Electronic transmission control unresponsive; Vehicle locked in park until manually manipulated; Lift gate mechanism activation causing shift to park automatically while in traffic
Repairs/costs cited: Lift gate mechanism replaced; on/off/start button replaced. Transmission pump failure requiring repair at 12,000 miles.
Limp Mode / Loss of Acceleration with Warning Lights
Vehicle enters limp mode unexpectedly, losing normal acceleration response while engine RPMs spike into red zone. Multiple warning lights illuminate. Condition clears after restart but repeats intermittently.
When: Multiple occurrences within first year; pattern repeats several times for affected owners
Symptoms owners cite: Limp mode activation; Loss of normal acceleration; RPMs spike into red zone; Multiple warning lights illuminate; Condition resolves after shutdown and restart
Repairs/costs cited: Dealer unable to duplicate problem on scanner; no diagnostic codes recorded. One owner reports radio and Apple CarPlay issues concurrent with propulsion problems.
Hybrid EV-to-Engine Transition Failure
Vehicle stalls during transition from EV battery to gas engine operation in hybrid mode. Engine fails to start or respond despite multiple restart attempts. Persists for 40+ minutes before vehicle eventually cooperates.
When: Within first months of ownership (April 2025 lease start, incident reported shortly after)
Symptoms owners cite: Vehicle stalls when EV battery attempts to switch to engine; Engine will not start; Dashboard displays engine and battery lights; Dash instructs to push brake and hit start button repeatedly; Unable to shift gears; Requires extended shutdown before restart succeeds

Repairs/costs cited: Start/stop battery replaced by dealership. On/off/start button replaced. Each repair required approximately one week in shop.
Autonomous Braking and Warning System Malfunction
AEBS (Advanced Emergency Braking System) and collision avoidance system activates inappropriately with no obstruction present, causing sudden deceleration or dashboard warnings to stop.
When: Within first 3 weeks and throughout first year of ownership
Symptoms owners cite: AEBS alert triggers with no obstacle in front of vehicle; Dashboard beeps and instructs driver to stop without cause; Shifter blinks demanding shift to park; Sudden deceleration without driver input
Codes mentioned: AEBS alert
Repairs/costs cited: One owner involved in accident when AEBS activation caused vehicle to shift to park and lose power on freeway, resulting in rear-end collision.
Recall Repair Execution Issues
