2020 Jeep Grand Cherokee SRT engine problems

“I brought my jeep in for a concern about an antifreeze leak on 1/3/25. I had 130,112 miles on my vehicle and was my warranty expired at 125,000 miles. They thought it was a water pump gasket at the time. I took my jeep back on 10/30/2025 and they confirmed a head leak, that wasn't checked last time. This is a safety issue since it has been confimed that other jeeps within same year have the same issue. If I am driving on the interstate and this issue got worse, then it will be a safety issue for everyone driving around me and me and my passengers in the vehicle as well. It has been inspected by Murray Dodge and Jeep. I have not gotten any warning lamps, messages or symptoms prior to failure. First appeared before 1/3/25. I was 5,000 over my mileage- since I was a traveling RN at the time.”

“Camshaft and lifter failure at 52,102 miles on Pentastar V6 Motor. This has been a known issue to this motor and no recalls. My vehicle is with the mechnic getting fixed. My vehicle was not drivable after diagnostics at my mechanic. I had potential for enfgine failure due to metal on metal camshaft. I was at risk of serious injury if I did not take my vehile in. There were no check engie lights to alert me of an issue. I noticed a slight ticking noise that was not normal. Could not be heard over the radio. Yes this problem has been reproduced at my independant service center. It has not been inspected to my knowledge by the manufacturer, police, insurance other than my mechanic. There were no warning lamps, messages or other symbols prior to my failure other than a noise I noticed when my radio was off that was not normal.”

“while riding vehicle just shuts off and stops. message on dash states put vehicle in park to start vehicle. Do that and vehicle starts and runs. First time this happened 6/13/25 went one week no problem then on 6/25/25 happened again took to service station no codes thrown.”

“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.”

“[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.…”

“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?”
