2021 Jeep Grand Cherokee LRecalls, problems, MPG & safety

“My 2021 Jeep Grand Cherokee L Overland has experienced repeated and escalating safety‑related failures involving the electrical system, telematics/SOS functions, powertrain components, and suspension. These failures have continued despite major warranty repairs and now pose a significant safety risk. Timeline of Defects: In August 2026 at ~52,276 miles, the vehicle required over $10,000 in repairs. Failures included: no A/C cooling, compressor and fan not engaging, evaporator leak, low refrigerant, and A/C clutch not activating. The driver seat cooling failed, the seat fan dragged, and both massage seat modules were shorted. The engine had an oil pan leak, idler and tensioner noise, and collapsed engine mounts. Immediately after these repairs, in September 2026, new electrical and safety issues began. Jeep Connectivity stopped working, purchased WiFi failed, and both the Assist and SOS emergency functions became inoperative. The vehicle displayed incorrect warnings (low oil pressure, low tire pressure) and experienced intermittent no‑start conditions requiring towing. Multiple system alerts appeared at once, suggesting BCM, gateway module, CAN‑bus, or…”

“STELLANTIS SPECIAL INVESTIGATION # 98439287/FOLOW UP FOR NHTSA COMPLAINT # 11769254/STELLANTIS CATASTROPHIC STRUCTURAL FAILURE / RECALL REMEDY FAILURE: - The front wheel and upper control arm completely separated from the steering knuckle while driving on the road. On October 5, 2026, while driving on a public road, my 2021 Grand Cherokee Limited suffered a catastrophic structural component failure where the wheel and upper control arm completely separated from the steering knuckle, causing an immediate and hazardous loss of steering control. This exact failure matches the critical safety components covered under an active manufacturer safety recall 10B/NHTSA 24V-132. The recall was repaired at the dealership on 08 July 2024. Despite the component failure matching an open safety recall, Stellantis is stonewalling the recall remedy. Stellantis corporate customer service is improperly misclassifying this life-threatening structural failure as a standard parts warranty issue rather than a safety recall failure. Consequently, they have denied the provision of a loaner or rental vehicle, leaving me without safe transportation. Furthermore, the manufacturer is…”

“I own a 2021 Jeep Grand Cherokee L covered under a Mopar Maximum Care extended warranty. My vehicle frequently displays the following safety-related warnings: - Auto Emergency Braking (AEB) Limited Functionality – Service Required - Blind Spot Alert Unavailable – Service Required - Active Lane Management (ALM) Unavailable – Service Required These warnings occur randomly, sometimes appearing and disappearing repeatedly within seconds. Because the malfunctions are intermittent and unpredictable, they are difficult to reproduce during a scheduled inspection. I have documented multiple incidents through photographs and videos. I brought the vehicle to an authorized Jeep dealership, where technicians conducted an approximately 50-mile test drive but could not reproduce the warnings. Despite reviewing my documented evidence, both the service department and service manager stated that no further action could be taken unless the warnings appeared during their inspection. This response is particularly concerning because the warnings involve critical safety systems, including automatic emergency braking, blind spot monitoring, and lane management. Their intermittent…”
