What stands out
Owners have filed 30 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.
Among the 5 model years of Jeep Gladiator in our records for electrical problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2021 Jeep Gladiator electrical system suffers from pervasive auto start/stop failures that violate the owner's manual. Owners report the engine shutting off unexpectedly when the driver's seat is empty, the seat belt is fastened, the hood is closed, or HVAC controls are adjusted—conditions the manual explicitly states should prevent auto-stop. The instrument cluster fails to display the required STOP/START READY message before shutdown. Multiple dealership service personnel and four independent shops have reproduced these malfunctions and flagged them as safety hazards; FCA Technical Advisors dismiss them as "operating as designed," directly contradicting published guidance.
Unwanted auto-start events occur when the AC is on, brake pedal pressed, fan is activated, or driver's door opens—again, not listed in the owner's manual as start conditions. A documented case of sudden unintended acceleration caused three collision incidents over several months despite brake application; the dealership found no fault.
Battery failures plague the fleet: owners report new batteries draining within days with no identifiable load, and one owner experienced four battery replacements since June 2021. A wiring harness chaffing the DPF caused complete electrical shutdown while driving through an intersection; FCA issued a Technical Service Bulletin for this known problem.
Additional failures include instrument cluster blackouts, key fob communication loss, door lock switch failures with improper repairs, rear-view camera malfunction when warm, center brake light LED failure at 30,000 miles, and auto-shifting to Park without driver input. Many repairs were denied warranty coverage or required extended dealer downtime without resolution.

What owners are reporting 1 most recent
I was driving my 2021 Jeep Gladiator and stopped at a red light at a busy intersection. When the light changed to green, I removed my foot from the brake and attempted to go through the intersection. Instead of moving forward the truck engine turned off and would not restart. As this was a busy intersection this was an extremely dangerous situation for both myself and other motorists. A local…
