Buyer takeaway: The 2024 Jeep Grand Cherokee—especially the 4xe hybrid—carries multiple unrepaired safety recalls, most critically an engine sand-contamination defect with no fix available since November 2025. Stalling, transmission loss, hybrid-system warnings, and lack of dealer solutions are common owner complaints; if you're considering a used model, verify recall status and demand proof of repair completion before purchase.
The 2024 Grand Cherokee engine cluster is dominated by one critical unresolved issue: Recall 78C (NHTSA 25V-766), a sand-contamination defect in the engine casting that Stellantis officially acknowledges can cause catastrophic engine failure, vehicle fire, and sudden loss of propulsion. As of April 2026—five months after the recall was issued in November 2025—no remedy has been developed, parts remain unavailable, and stop-sale orders remain in effect for affected vehicles, particularly the 4xe hybrid models. Multiple owners report being denied buybacks despite the acknowledged danger, forced to either pay lease fees on unsafe vehicles or sit with unrepaired cars.
Owners also document stalling events at highway speeds (35–55 MPH) without warning lights, sudden loss of power, and failures to restart. One incident occurred at just 500 miles. Transmission failures with complete power loss and battery-system warnings ("Service Hybrid System" intermittently shutting the vehicle down) compound the picture. A high-voltage battery fire-risk recall (NHTSA 25V741) likewise carries no available remedy.
Additional reported problems include rough idle, hesitation under acceleration, PCV valve freezing in cold weather (with manufacturer denying warranty coverage), and exhaust fumes entering the cabin. One owner found conflicting recall-status documents at the dealership and was later notified of multiple unrepaired recalls via NHTSA's VIN lookup—recalls the dealer never disclosed. Dealers consistently report parts on backorder and inability to complete recall work. Manufacturer responsiveness ranges from silence to offering token payments while refusing real solutions.
