“It and it had a weird knock to the engine. Did get searched five times until it was figured out. It was the lifters and camshaft that failed at 82,000. it was fixed it did stall on the highway once before that. complete fix the water pump issue. for the fuel system the EVAP code keeps showing up every few thousand miles even though it's been checked and serviced. No leaks of any kind even the very small code leak. No leaks were found in any parts of the car”

“Unknown or uncertain about needing a recall. Recently my car has been having trouble with acceleration in the sense that either it will lag or stall out and at times will give acceleration even without me trying to depress the gas harder. It sputters like it either cannot get gas or the fuel system is faulty, it keeps throwing codes and the check engine light dings and flashes. Cruise control sometimes will not come on, theres a burnt smell and rough idles, i have noticed a deep humming sound under my feet while driving, and sometimes when shifting from park to gear it jerks really hard, going down the road it acts like it takes too long to shift. It really is very scary when it does these things, its a daily occurrence. Sometimes it drives just fine then all of a sudden will malfunction. I've only had the car not quite 2 years and they said they repaired the recalls in 2018, after I had scheduled an appointment for July 2025.”

“Transmission failed. Stuck in drive while on busy road, could not put vehicle in park or neutral and could not turn vehicle off. Drove very slowly to dealership because no one would tow without being able to turn it off and stuck in drive. Dealership did diagnostic and decided transmission needed replaced. Safety of other drivers were put at risk because car could not be taken out of drive and could not be shut off. No warning lamps, no messages prior to failure. Message came on to place vehicle in park to reset after trouble started but nothing worked at that time. Would not go into neutral or park. The emergency brake had to be used to keep car from moving forward. I recently had transmission replaced (1/24/2025) and now have a check engine light on with a code reads P1DCA Park Sensor Circuit Open”

“While driving on the freeway, in the fast lane, with children in the car the car lost all ability to accelerate, and lights came on. We had to coast to the side of the road and stop the car on the shoulder. We were almost hit while stuck there waiting for a tow truck. Nothing in the car worked, we were lucky to get one car window down as it was 103 degrees. We couldn't get out of the car bc we had two toddlers in car seats and no where safe to go. So we sat there praying and called family to come get us since we couldn't get kids into tow truck. Towed car to jeep and jeep wouldn't even look at it bc they were 3 weeks out diagnosis so we towed to closest mechanic and spent 2k to replace fuel pump. No warning lights messages or symptoms before. 6 months later the car started to shake when turned on and we took it to local mechanic who said I hope you have an extended warranty since jeep has known problems with cylinders and gaskets. We immediately took it to Jeep who said the head cylinders were blown and it was leaking. The car only has 60,000 miles so to have a terrifying situation on the freeway and then issues with the engine was equally scary when it is our family car.”
