NHTSA Complaint #11601026 — 2021 JEEP WRANGLER

While climbing a mountain pass between 2000' and 2500' MSL and passing some vehicles at approximately 70 mph, the vehicle suddenly lost power and multiple warning lights illuminated. These included: Service Electronic Throttle Control, Check Engine Light, Automatic Emergency Brake system failure, Adaptive Cruise Control system failure. After the initial power loss, the engine seemed to partially recover and could be driven below 60 mph until the vehicle was shut down and restarted. There were no signs or warnings of any impending failure. The coolant, engine oil, and transmission temperatures were well below the published limits. The danger was the power loss was sudden, unexpected, and at a critical time when passing large trucks and in the vicinity of heavy traffic with no emergency parking available. This reported event is the fourth time it has occurred. The vehicle has been taken to the dealer to repair it, and the dealers have attempted three times to fix it (all three times dealer fixed something different). All three times they reported the issue had been fixed, yet it has re-occurred after each time. It is currently scheduled for a fourth dealer visit.
