Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Engine stalls represent the most critical complaints across these 19 submissions. Multiple owners report complete loss of propulsion with no warning lights, occurring at highway speeds (70 mph), city speeds (30-45 mph), and during coasting. One stall incident triggered a rear-end collision after the vehicle died exiting a car wash. Restarts occur without stored diagnostic codes, making these events difficult for dealers to diagnose or replicate. Two NHTSA recalls (23V503 and 25V576) address control module and hybrid software defects causing similar symptoms.
Hybrid system failures appear frequently: battery fails to provide power assist during acceleration, creating dangerous gaps when merging. One owner after battery recall work reports check-hybrid warnings with clunk sounds and red wrench warnings that clear within minutes with no stored codes.
Engine mount noise—a thwomping sound after 30 miles of driving in gear—is widespread per owner reports and acknowledged in TSB 09-015-22, yet Jeep has not issued a recall despite acknowledging faulty older mounts. Dealers cannot reproduce the issue during short test drives, blocking warranty repairs.
Additional failures include excessive oil consumption at 3,000 miles with loud clicking on hills, charging system failures leading to dead batteries and multiple tows, unexpected automatic downshifts on interstates, and a coolant pump leak at 23,000 miles. One owner reports a $14,000-$18,000 engine replacement at just over two years old, with warranty covering only $12,500 after $5,500 owner payment.

Failure modes owners describe
Engine stall / loss of propulsion
Engine shuts down suddenly during normal driving with no warning lights or audible alarm. Occurs at various speeds (30 mph coasting, 45 mph uphill, 70 mph highway). One owner with calibration background suggests decel fuel shutoff malfunction. Another stall occurred while accelerating, with RPM increase before shutdown. Restarts after shutdown with no stored codes.
When: Between 1,000 and 85,095 miles; multiple occurrences reported within short intervals
Symptoms owners cite: Complete loss of engine power with no warning lights; No response to throttle input; Engine restart successful after stall; Loss of steering assist and braking assist during stall; No diagnostic codes recorded in some instances
Codes mentioned: Recall 25V576 (hybrid control software defect), Recall 23V503 (internal control module failure)
Repairs/costs cited: One owner paid $5,500 out-of-pocket after warranty ($18,000 total repair cost quoted); engine replacement ordered but delayed over one month with multiple missed completion dates. One case diagnosed but not yet repaired; another sent to dealer for diagnostics. Most cases have not been inspected by dealer.
Recalls/TSBs owners mention: Recall 25V576 (September 2025) and Recall 23V503 (June 2023); manufacturer was aware of one excessive oil consumption/loud clicking case but advised no fix available
Engine stalling with loss of acceleration / limp mode
Vehicle experiences loss of acceleration power or enters a limited-power state where speed cannot exceed approximately 30 mph. One instance involved hesitation followed by power loss at low speed with electrical burning odor. Another case showed RPM increase but no acceleration. Multiple occurrences within short periods.
When: 1,000 miles and repeated occurrences; some at 85,095 miles
Symptoms owners cite: Inability to accelerate beyond ~30 mph; RPM increase without corresponding acceleration; Hesitation before power loss; Electrical burning odor (one case); Loss of motive power on uphill grades; Loud clicking sound during power loss (one case)
Repairs/costs cited: One case: coolant pump replacement performed but failure continued. Most cases not diagnosed or repaired; dealers unable to replicate symptoms.
Engine mount noise / vibration
Low-frequency thwomping or knocking noise from engine area, especially on passenger side, occurring after 30 miles of driving when vehicle is in gear. TSB 09-015-22 addresses this; older engine mounts (non-NIK AG or newer) are identified as faulty. Owners report this is widespread on Jeep forums but difficult to reproduce in shop environment. Noise is a significant distraction.
When: 27,000 miles; develops after approximately 30 miles of driving
Symptoms owners cite: Low-frequency thwomping or knocking noise; Noise occurs only when in gear (D or R); Noise appears after ~30 miles of driving; Difficult to reproduce in dealership short test drives
Repairs/costs cited: Engine mount replacement suspected. TSB 09-015-22 acknowledges faulty older mounts; newer NIK AG or later versions required. No repair completed due to inability to recreate in shop.
Recalls/TSBs owners mention: TSB 09-015-22 issued; acknowledges mount design issue but no recall issued despite widespread reports
Hybrid battery system failures / loss of hybrid assist
After battery recalls (mentioned as 95B high-voltage battery recall), hybrid system fails to engage or switches unexpectedly. Battery fails to provide power assist at low speeds, creating gaps in acceleration when driver needs immediate response (merging, turning). System warnings display intermittently without stored error codes. One case involved large clunk sound and transmission/hybrid shift concern with red wrench warning.
When: Post-recall service; multiple occurrences within short intervals
Symptoms owners cite: Battery fails to kick in when accelerating from low speed; Loss of motive power / power deficit at low speeds; Intermittent hybrid system offline warning; Check hybrid system warning lights; Large clunk sound (possible transmission or hybrid shift); Red wrench warning displayed; Warning clears after ~1 minute with no stored codes
Repairs/costs cited: Multiple battery recalls performed (95B high-voltage battery recall); issue persists post-recall. Dealer unable to diagnose due to lack of stored codes.
Recalls/TSBs owners mention: High-voltage battery recall 95B issued; one owner reports battery fire risk warning advises not to charge or park near structures with no fix available
Excessive oil consumption
Engine consuming oil at abnormally high rate, requiring refill of approximately one quart every several weeks. Occurred at very low mileage (3,000 miles) and was accompanied by loud clicking noise and loss of momentum on uphill grades. Dealer advised manufacturer was aware of failure but no fix available.
When: 3,000 miles
Symptoms owners cite: Rapid oil depletion (one quart every several weeks); Loud abnormal clicking sound while driving uphill; Loss of forward momentum on uphill grades
Repairs/costs cited: Vehicle not repaired; dealer stated no fix available from manufacturer
Recalls/TSBs owners mention: Manufacturer aware of failure; no fix available per dealer report
Engine starting failures / electrical charging issues
Vehicle fails to start on multiple occasions. Associated symptoms include flickering lights, service charging system notice, hybrid system offline warning, check engine light, and battery drain to dead. Requires towing and leaves owner stranded multiple times.
When: Multiple occurrences at undisclosed mileage
Symptoms owners cite: No-start condition; Flickering lights; Service charging system warning; Hybrid system offline warning; Check engine light; Battery completely discharged
Repairs/costs cited: Vehicle towed to dealership multiple times; specific repair details not provided
Unexpected automatic downshift
Vehicle automatically shifts to lower gear multiple times, creating dangerous situation requiring vehicle to be pulled over and placed in park before continuing. Reported as especially hazardous on interstate highways.
When: Multiple occasions at undisclosed mileage
Symptoms owners cite: Automatic downshift without driver input; Loss of vehicle control requiring emergency stop; Requires park and restart to resume normal operation
Coolant pump leak
Coolant pump began leaking antifreeze at low mileage. Diagnosed and replaced by dealer under warranty.
When: 23,000 miles
Symptoms owners cite: Antifreeze leak
Repairs/costs cited: Coolant pump replaced under warranty
