-The new 2021 Jeep Grand Cherokee L-Limited was made to be a third, row off-road, all weather driven vehicle. #1: The front windshield is flush with the front pillars. This causes accumulated snow or off-road dirt to easily be pushed to the driver side window (with no way to wash off) and blocking the driver’s side mirror. This makes it impossible to to use the blind spot light on the side…

What stands out
Owners have filed 65 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA electrical complaint has been filed on this vehicle in over 4 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2021 Grand Cherokee has widespread electrical issues ranging from screen and module failures to complete engine shutdowns, fires, and safety system losses—many occurring within days of purchase at low mileage. Dealerships struggle to replicate or fix problems, and Chrysler/Stellantis has offered little support beyond trading vehicles.
Electrical problems dominate complaints about the 2021 Grand Cherokee. The most dangerous issue: the vehicle shuts down unexpectedly while driving at all speeds, with no warning lights in many cases. Owners lose power steering and brakes simultaneously, forcing them to coast to safety on highway shoulders while dodging traffic. Engine cranks slowly or won't turn over despite new batteries, and dealerships have replaced batteries twice on the same vehicle without fixing chronic drain.
Infotainment screens go blank mid-drive or fail to boot at startup. Android Auto disconnects repeatedly. The touchscreen controls everything—radio, HVAC, backup camera—so a blackout defeats multiple functions. Software updates don't stick; dealerships sometimes say no update exists for the owner's vehicle.
Critical modules fail: Body Control Module, Occupant Restraint Controller, parking sensor module, and PCM, each triggering cascading failures in other systems. Owners report false SOS alerts, loss of brake and power steering lights, parking brake engaging while driving, and auto-park locking up in mid-maneuver.
Several fires have been documented—one started in the parked, off vehicle two hours after being turned off; another erupted from remote-start activation; a third melted a charging cord in the third row. Smoke and melting plastic smell preceded full engulfment in at least two cases, with no prior warning lights.
Brake and steering systems lose assist simultaneously on highway speeds with multiple warning lights illuminating at once, forcing owners to muscle the wheel and pump brakes. Blind spot sensors malfunction because windshield design traps snow and dirt on mirrors, rendering them useless. Door locks don't hold; children can open doors from inside while driving. Cold weather drains batteries completely, stranding occupants in sub-zero conditions.
