2024 Jeep Grand Cherokee powertrain problems

The failure pattern owners describe
Buyer takeaway: A 2024 Grand Cherokee can strand you with unshiftable transmission, unpredictable electrical shutdowns, or catastrophic engine failure—and Jeep's known remedy for the most dangerous defect isn't even available yet. Expect multiple recalls, battery replacements, and dealer visits that don't fix the underlying problems.
Owners of 2024 Grand Cherokees report a cascade of powertrain failures across electrical, transmission, and engine systems, many surfacing before 15,000 miles. The most severe is NHTSA Recall 25V-766 (FCA 78C)—sand contamination in the 2.0L engine block that can cause catastrophic failure, loss of propulsion, and fire—which has been open 80+ days with no repair parts available. Stellantis acknowledges the defect but offers no interim transportation or buyback.
Transmission issues cluster around TCM and valve body failures at low mileage, causing vehicles to shift into neutral, refuse Drive, or decelerate abruptly from highway speed without warning. One owner lost all power at 65 mph on a crowded freeway; several dealership repairs have not been permanent.
Electrical system failures are frequent and frightening: vehicles lose all power steering and brake assist, become stuck in RUN mode unable to shut off (requiring manual battery disconnection), or shut down completely while driving at speed. One owner had both batteries fully drained by 4,000 miles and replaced five batteries in one year despite all accessories being off when parked.
Hybrid 4xe models lost electric-only propulsion capability after recall software updates—the manufacturer reduced performance as a workaround rather than fixing the underlying issue. Multiple owners report losing propulsion on highways, with dealer diagnostics consistently returning "cannot duplicate" or "no codes found."

Engine Contamination (Sand in Casting) – Unrepaired Recall
NHTSA Recall 25V-766 (FCA Recall 78C) identifies sand contamination in the 2.0L engine casting that can cause catastrophic engine failure, loss of propulsion, vehicle fire, or crash without warning. The recall has been open 80+ days with no remedy available.

Codes mentioned: NHTSA 25V-576, NHTSA 25V-741, NHTSA 25V-472
Repairs/costs cited: Manual battery disconnection required to power down; dealer resets ECM but provides no explanation or permanent fix
Recalls/TSBs owners mention: Multiple recalls issued (25V-576, 25V-741, 25V-472) but defect recurs after repair; dealer unable to diagnose; manufacturer provides no assistance
Transmission Shift and Acceleration Failures
Transmission fails to respond or shifts erratically. Accelerator pedal unresponsive; vehicle cannot exceed 20 mph or surges forward unintentionally. Shifting to neutral and back to Drive sometimes restores function temporarily.

Repairs/costs cited: Shifting to neutral and back to Drive temporarily restores function; no permanent repair documented
Recalls/TSBs owners mention: Recall 25V-766 issued but parts unavailable; dealership unable to duplicate or diagnose; manufacturer exceeded reasonable repair timeline
Hybrid System Malfunction and Loss of Electric Propulsion
Hybrid 4xe models lose electric-only propulsion capability after recall software updates. Vehicle defaults to combustion engine only or experiences sudden loss of power in electric mode. Performance degradation treated as 'fix' rather than true repair.
When: After recall 68C software update (September-October 2025); 60,000+ miles; 1% of fleet per NHTSA 25V-576
Symptoms owners cite: Electric-only mode unavailable; vehicle restricted to combustion engine; Loss of power while in hybrid mode at 45 mph; Hybrid warning light no longer illuminates after software update; Message 'Electrical mode unavailable' displayed; Sudden loss of propulsion requiring vehicle restart; Loss of electric power reserve capability
