The National Highway Traffic Safety Administration (NHTSA) has a bulletin about coolant leaks in Jeep Wranglers with 2.0L engines: Bulletin: 07-001-20 REV. A, dated April 9, 2020 Vehicles affected: Jeep Wranglers built before November 30, 2019 with a 2.0L I4 DOHC DI Turbo Engine or 2.0L I4 DOHC DI Turbo Etorque Engine Issue: The coolant inlet tube fasteners may become loose, causing a coolant leak Solution: Remove the coolant inlet tube fasteners, clean the threads, add Thread Loc, and reinstall Tightening torque: Tighten to 11N∙m (8ft. lbs.) A coolant leak can cause the engine to overheat and potentially lead to engine failure. Engine fan was not shutting off after leaving a covered parking garage and an engine alert appeared and displayed that the engine was overheating. Had my jeep towed home. We were able to see that the main coolant reservoir was empty and that there was dry coolant all around the engine. Our jeep has not been fixed and is not drivable. Need guidance as there isn’t a recall on this but a known issue, and you have a bulletin out about it.

Had to get it towed. There were no loud noises no oil leaking nothing. No indicators before hand of the Jeep needing oil change or misfiring. Got it diagnosed and they said my engine seized up and I had blew a piston. WITH NO WARNING or indicator of anything in the months weeks days prior. My engine light never came on.

Vehicle only had 21421 miles on it. We were having issues with the Jeep reveling at highest RPM when turned on. This happened a handful of times and then it began to seem like it was not going to stay started and was going to stall. We took it into dealer for oil change and reported the issue said they couldn’t find anything. Issue persisted took it back and they ran diagnostic said they couldn’t find anything. Still had the issue occurring so took it back and they said it needed a new starter so they replaced that. Then issue got worse and was stalling out and shaking. Took it back again and they are now replacing the engine. This was really shocking. This is the 4th Jeep wrangler I’ve owned in my life and so have NEVER had major issues with any of them before only normal wear and tear type repairs and upkeep.
