NHTSA Complaint #11713827 — 2020 JEEP GLADIATOR

Engine failure due to coolant leak: in December, 2025, vehicle was towed to dealership due to overheating engine. While driving home from work, Vehicle was exhibiting engine overheating including temperature warning lights, temperature gauge fluctuating from normal to extremely high, a strange sound coming from the front of the vehicle (almost like a fan was not working) and running rough, like a diesel idle. I immediately pulled the vehicle off to the side of the road & shut it off. (Fortunately engine didn’t seize or exhibit these symptoms while I was on the highway just minutes before) I called dealership & they said it needed to be towed in. After having my vehicle for 10 days, Dealership stated thermostat needed to be replaced. Vehicle then exhibited same symptoms a few weeks later along with a check engine light, vehicle is returned to dealership. Dealership NOW tells me they’ve “seen enough of these to know that it’s most likely going to need a left side cylinder head” due to coolant leak into the engine. I am now aware there have been multiple reports to NHTSA for similar issues and that a service bulletin has been issued to the dealerships for this very reason: its a KNOWN issue with no recall in sight. Jeep at this juncture, acknowledging it’s a problem, REFUSES to assist with very costly repair, instead suggesting I should report to NHTSA.
