The start-stop system reports unavailable, then within a few miles of driving, the check engine light will come on, followed by problems with the transmission shifting gears, sometime causing the vehicle to stay in first or second gear while accelerating and creating a dangerous driving situation. Power cycling the vehicle sometimes helps. Diagnostic trouble codes show low voltage in one or more O2 sensors, "too lean" warnings and cylinders randomly misfiring. Engine runs very rough at idle with the strong smell of gas in the exhaust. Dash information shows battery voltage around 12.3 at start up increasing to low 13 while idling. This occured around 40,000 miles and dealer replaced the aux battery and reset system. It occurred again around 60,000 miles (20 months later) and owner replaced both auxiliary battery (testing showed bad) and main battery. System functioned normally after resetting codes. It occurred again about 8 months later at 72,000 miles. The F42 fuse was pulled, cleared codes and reset computer by removing battery power for 1 hour. System returned to normal.

On May 27, 2026 at approximately 11:00 PM, my 2020 Jeep Gladiator Overland (VIN: [XXX] ) suffered catastrophic engine failure during normal operation at 78,190 miles. The alternator seized, causing the harmonic balancer (crankshaft damper) to fracture. The broken balancer fell into the engine block, causing extensive internal damage requiring complete engine replacement at significant cost. This failure sequence points to a design and/or manufacturing defect in the OEM alternator and/or its mounting system on the 3.6L Pentastar V6. A properly designed alternator should not seize with enough force to fracture the harmonic balancer and deposit debris into the engine block under normal operating conditions. The vehicle was not involved in any accident or operator abuse. It was being driven normally with no prior warning — no dashboard lights, no unusual sounds, no prior related mechanical issues. I request NHTSA investigate whether this failure pattern is systemic across 2020 Jeep Gladiator vehicles and other 3.6L Pentastar V6 platforms, including the Jeep Wrangler, Ram 1500, and Dodge Durango. Sudden complete engine failure at highway speeds is an immediate crash hazard to the driver and surrounding motorists. I respectfully request a formal defect investigation and, if warranted, a safety recall with full remediation and reimbursement of repair costs to affected owners.

On Friday, May 22, 2026, at approximately 59,442 miles, the vehicle's instrument panel cluster (IPC) failed suddenly and without warning. The vehicle was driven to a store in [XXX] , with the display functioning normally, but upon restarting the vehicle less than an hour later, the central information screen went completely blank. The screen remains permanently blank and fails to display any driver information. At night, turning the vehicle on causes the screen to emit a faint dark gray backlight, but no text, gauges, or data populate. This failure creates an immediate safety hazard. With a permanently blank cluster, I am forced to drive without access to a speedometer, fuel gauge, odometer, or critical vehicle warning and safety lights, severely impacting my ability to maintain safe speeds and monitor vehicle health on public roads. The vehicle was inspected on May 27, 2026, by an authorized Jeep dealership (Lopp Motors in Dodge City, KS). The technician confirmed the failure and noted: "INFO SCREEN BETWEEN TACH AND SPEEDO IS BLANK. NO CODES IN SYSTEM PERTAINING TO CONCERN. TECH TRIED TO RESET CLUSTER AND PERFORMED PROXI ALIGNMENT – WOULD NOT ALIGN. ATTEMPT A VEHICLE CONFIG RESTORE – STILL NO CLUSTER OPERATION. INSTRUMENT CLUSTER REQUIRES REPLACEMENT." This identical component failure is the subject of NHTSA Campaign 24V-652 (Jeep Recall 30B); however, my 2020 model year VIN is currently excluded due to manufacturer time-in-service parameters. The vehicle and the failed component are available for inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Instrument cluster completely quit working. We cannot see speed, if we have gas, tire pressure, mileage, oil temp, nothing. The whole thing is blacked out. No warning, dealer confirmed problem. This is a massive safety problem as we have no access to any information.
