I bought this car as a 1 year old vehicle with less than 20k miles. Since my first oil change, my mechanics have mentioned that it is losing quite a bit of oil. The jeep has died in intersections 9x due to low oil pressure. The vehicle crossed 60k miles a month ago, and is now misfiring. After a leak down test was performed, they stated that the engine needs to be replaced due to a 40% leak on cylinder 3 and a 30% on all other cylinders. Unfortunately, the engine is now out of warranty.

Driving on highway at 70 MPH up a minor incline, the vehicle started hesitating/chugging and then the accelerator pedal stopped responding. Vehicle stalled and coasted to stop where the idle was rough and then died. Initially, would restart, but then stall out. For the next 3 hours (while waiting for a tow), the electrical system was flaking out - intermittently flashing any error in its wheelhouse. Restarted next day and idle very rough/misfiring, engine light blinking and decent cloud of black smoke generated. Initial report from shop is that the engine oil is sludge (changed 5k miles ago), battery is completely dead (was already replaced at 15k miles) and a spark plug end is bent and in horrific shape. Vehicle has 25k miles and has been in service for 4.2 years.

Have had vehicle since 2018. For 2 years, I have had 3 cylinder misfires (with the last one about to happen at any moment) and my vehicle has stalled while driving (once on the freeway) about 8 times. I had to pull over each time to a complete stop. The vehicle stating "vehicle cannot change gears until stopped." once I turned off the engine, it takes about five minutes to restart the engine. The cylinder misfires always begin with aggressive jerking while vehicle is in motion. Lasting a few months, leading to aggressive shaking once misfired. On occasion, while vehicle is stopped, seat belt will also not buckle and in the last two years seat belt has also come unbuckled twice while vehicle is in motion.
