2020 Jeep Grand Cherokee

I bought the vehicle Dec 29, 2024 and it had 79000 miles on it. I use it for work , that is driving to and from my job and to the bank and back for work. I would say that in March of 2025 I went to the bank and I got in to leave and put the vehicle into reverse and it would not go into reverse and a the engine light came on. I had to shut the vehicle off and wait 5 minutes and then try again to go into reverse. When I put it into reverse the r was flashing on the shifter and it said something about needing something to be serviced. So when I looked it up it said that was a sign the transmission was failing. I drove it a couple more times and it only happened 3 times total when it was unable to shift going forward. So I took it to a shop and was informed that the transmission was needing to be replaced. There is no reason the transmission should be going out of it. I live 5 miles from where I work and 15 miles from the bank. I dont abuse my vehicles so what is there an issue with the transmission.

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 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.

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?

While I was attempting to pass a vehicle on a two-lane highway, my engine started misfiring and I lost engine power and it almost caused a head-on accident. The engine had to be replaced because the camshaft was worn on bank 1 and after doing some research there seems to be a lot of issues with this engine and the rocker arms which wears the camshaft down. There was a lot of metal in my engine which caused them to have to replace it. I researched recalls and there is nothing but after speaking with the dealership they confirmed that there is a known issue with this engine.
