[XXX] Utility 4D Altitude 4WD 3.6L V6 2020 Jeep Grand Cherokee My 2020 Jeep Grand Cherokee with 3.6L Pentastar V6 engine check engine light came on at 115,000 miles with a P0305 code. The P0305 code for a 3.6L Pentastar V6 engine indicates a misfire in cylinder number five. The week prior I performed a coolant flush and fill with the proper Mopar coolant. A few days later the water pump weep hole started leaking. I replaced the water pump and changed the spark plugs. A few days after this was when the P0305 check engine light came on and I could feel the engine starting to stumble from the misfire. No indication of overheating, coolant temperature was normal between 180 F and 210 F. I kept checking the coolant level and noticed the level dropping after a few days. There was no indication of a coolant leak after replacing the water pump. No coolant in the oil, or oil in the coolant and no white cloud from the exhaust from the coolant leaking into the combustion chamber, typically caused by a blown head gasket, cracked head or block or warped head or block. I set an appointment at the Jeep service department, and they informed me the engine had to be replaced. They said they did a bore scope test and a leak down test to confirmed the coolant was leaking into the cylinder. There are hundreds if not thousands of reports from other owners of Jeep Grand Cherokee and other Jeep, Chrysler, Ram, Dodge owners reporting this same issue. The attached photos show no coolant mixing with the or oil mixing with the coolant, resulting in the coolant only leaking through the combustion chamber to the exhaust confirming the service departments findings.

The transmission went out in October 2024 and was replaced in November 2024. Since then, the valve body has been replaced twice and probably needs to be replaced again. The car does not shift into/out of third gear properly or consistently which causes very delayed acceleration. This is a safety hazard when entering the roadway, especially merging onto the highway. Chrysler is aware of the valve body being “bad” yet continues to “replace” with bad parts.

UConnect system is delaminating and experiencing “phantom” touches, often not allowing me to access things needed and choosing to do whatever it wants. This makes me unable to access “hands-free” via Bluetooth connection, etc., which creates safety issues. It also creates serious safety issues when the unit overrides driver choices, and is also distracting as the unit beeps and switches back and forth among options. This is a widespread issue that Jeep knows about and continues to leave good people to pay thousands of dollars to replace or just be out MANY features on this vehicle that all go through the system. This makes MUCH of this vehicle obsolete.

Took to dodge dealer and they told me they have been have problems with traction control, 4x4 problems, misfiring cylinders . They spent 5 days trying to figure it out and told me it was a process of elimination . Replace rear diff motor and that didn't work, replaced TCCM, that didn't work, replaced both batteries , that didn't work, new spark plugs, that didn't work, replaced coils on the side where #1 cylinder miss fire, that didn't work. I've spent approximately $6,000 and still have same problem. I do not have unlimited funds. What should I do next?
