2020 Jeep Grand Cherokee Powertrain & Transmission Problems

Rocker arms and lifters failed

I purchased this vehicle, November 2023 and by August 2024 the vehicle went into Griffin Hubs to get the engine replaced. They had the vehicle for over a month and a half when I received it back after the engine I had it for a day and a half and had to take it back because it was making a loud grinding noise coming from the engine which then they had to replace a second time because the engine was shredded and was told they were going to put a new transmission in as well, but instead of just replaced a piece, and then two months later, the negative terminal for the battery was replaced in about four months later I take it into the dealership again because as I was driving the vehicle pulled back three times and then shot forward and that happened seven separate times dealership said they could not find an issue and then in November 2025, the vehicle goals back into the dealership for overheating needing a new water pump because I was losing coolant with no leaks. Get the vehicle back two days later my coolant is empty tied again call the dealership they said if it happened again, bring it back in two weeks later it did the exact same thing. My coolant was emptied, but there is no leaks coming from under the vehicle and now last week as I was driving, the vehicle suddenly stopped accelerating and my gearshift wouldn’t catch any gears and as the vehicle is still moving my tires, then locked. The vehicle has been at the dealership for five days and they still cannot figure out what the issue is.

See attached document for complaint.

My vehicle is losing power every randomly literally cutting off and on. Flashing lights won’t start at time , next day drives completely fine. I do not understand

At approximately 54,000 miles the transmission is not shifting. I parked in a parking spot, go into a store. Then come out and the vehicle will not shift into park or reverse. The check engine light came on for the park by wire issue. These transmissions have been known to have rough shifting and my vehicle has been no exception. It’s shifted rough at low speeds and the eco mode and auto start/stop system have also made it feel less than smooth to drive.

Issue #1: The vehicle exhibits substantial cabin vibration, particularly affecting the steering wheel. This necessitates maintaining a firm grip on the wheel when operating at speeds of 30 mph and above. The vibration intensity escalates in direct proportion to the vehicle's velocity. It has been reported that this vehicle model has documented issues with rear drive shaft bushing failure, which may contribute to excessive play and vibration. Issue #2: The interior door trim applique has delaminated and broken. This issue has been previously reported in Service Bulletin 23-001-19 REV.B, Group: 23-Body, dated 8/10/2019, for a different Jeep model.

My 2020 Jeep Grand Cherokee Laredo 3.6 ENG vehicle is cutting off while driving, I was advise it the transmission shift gear transmission, Which needs to be replaced and the can change the TRANSMISSION ASSEMBLY - Remove & Replace 3.6L Eng, AWD on my vehicle. when I stop at the light the vehicle completely shuts off where I have to restart my vehicle. They said it was the 2nd battery which I changed and brought a new one. and the same day it still was cutting off. after several attempt in contacting them. I brought the vehicle into Chrysler Jeep Dodge of port Jefferson, and after reviewing they said I need to replace the transmission . I was also advised that there was a TSB Code that is now coming up # 21-00925 Revision C - P0733. I'm very upset as they're telling it current over the extended warranty at this time at 60,000 Miles. when I brought it in it was .. This should be a recall and they need to fix it I only had this vehicle for less then 5yrs brand new, when I started having these issues and can put me in a situation on the highway where I can get into a server accident. I strongly urger the RECALL as this is a known issue with this vehicle

Transmission needs fully replaced, certified technician said the see this all the time in these Jeeps. Dealership said they had to replace one at 56k miles, this car has 85k miles, well taken care of. Research shows this is a very common issue. Jeep needs to cover these transmissions and recall!

Transmission system failed causing slipping when going into 3rd gear. Dealership inspected it and is telling me the output shaft has to be replaced. The check engine light came on when it started slipping.

UNKNOWN. Electronic Stability Control service light activated intermittently for a couple days along with the 4WD service light. After 2-3 days, the ESC light remained lit. Twice when starting the vehicle, the 4WD low was activated without manually shifting gears, in which changed to normal within a minute later. Intermittently, when the vehicle braked to a stop and switched gears to reverse, the vehicle shuttered before continuing in reverse. Another incident while driving and coming to a stop at a traffic light, upon coming to a stop, the vehicle seemed to almost stall but reengage. The vehicle is at approximately 41,500 miles as of 4/1/2025. The vehicle was taken to a Dodge dealership in which report the transfer case needed repair. With under 50,000 miles and utilizing the 4WD only approximately 4 times within the 5 years of ownership with no issue, the transfer case may be faulty or a software update needs to be performed.

Car running fine no indication there was a problem, no lights on dashboard or sound. Jeep stalled on highway and engine light came on. Shut car off completely turned it back on and able to move to a safe location. Turned off car again for some time and when turned back on shift gear will not move into drive, reverse neutral. Needed to get it towed to mechanic who diagnosed it as a failed transmission at 88,000 miles. Towed to dealer who confirmed failed transmission. Was able to get cost assistance through jeep for 70 percent of cost but see the recent recalls on jeep because of transmission I feel it should have been a total replacement especially at u der 100,000 miles

At 100,000 miles , traction control light and 4wd service light came on. Dealer said rear diff motor replacement needed, and the TCCM . I replaced and problem still persists . Now red triangle come on dash and says pull to safety motor will turn off. Turning wheel it hesitates like it's not engaging correctly.

Driving down the interstate at 75mph, the vehicle all of a sudden lost the ability to accelerate and felt like it shifted into neutral. We were able to pull over to the side of the road safely and as we were getting out of the vehicle, we noticed flames shooting out from under the engine. My wife and I made it out safely and as we got about 100 yards away and looked back toward the vehicle, the entire front part of the vehicle was engulfed in flames. We sat along the side of the interstate and watched the vehicle burn for 20-25 minutes. We just had the vehicle in for service 6 days prior to get a new battery, a new aux battery, an advanced diagnostic, brake fluid exchange, and a fuel system service. The evening we picked up the vehicle from service, we got an email with a powertrain alert indicator. We then checked the app on the phone and everything in the powertrain section of the vehicle health report was green. I have several videos of the vehicle burning but it doesn't look like I can upload a video file.

My check engine light came on so I took my car into the mechnanic. They noted the following: "Removed intake manifold and find cylinder three spark plug appears ok. Spin engine over to top dead center cylinder three. Pressurized cooling system and find combustion in coolant. Suspect vehicle needs new head gasket." The mechanic said that is a manufacture defect that they have seen with many Jeep vehicles. I called Jeep to inquire, and they let me know that my VIN number is not included in an existing recall for this same issue. The suggested that I reach out to the NHTSB to ask that my car be included in the existing recall.

While traveling Vehicle intermittent hard shifts, or no shifts, goes into neutral unexcitingly, sometimes no reverse. SES light on. 77,278 miles Dealer advised stored code - TCM P0733-00 Gear 3 Shift Incorrect Ratio. Dealer also advised vehicle needs Transmission replaced, Repair estimate $5970.28 Previous issues include ABS system repair and engine coil pack issue.

The car will be driving and it all of a sudden stops and has all the lights on the dashboard coming on. Every single warning light coming on the car comes to a stop and will not move. This has happened three times and the dealership tells me they don’t know what the issue is.

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?

Transmission, available upon request for inspection. Clunk’s into reverse, or doesn’t engage at all. Code p1da8, p0733. Has been confirmed by dealer. Will throw check engine light occasionally. Also shifts hard between gears 3 and 4.

Transmission failure, vehicle will not start and will not shift into reverse, leaving driver stranded and stuck in vulnerable parked position. Check engine light comes on with P1B14-00 code - "Park by wire unintended park position". Engine light did not come on until after issue happened. Dealership diagnosed and confirmed issue and engine warning light code P1B14-00. They re-flashed vehicle ECU due to recall and that did not resolve issue. They are suggesting completely new transmission.

While at a complete stop, depressed the accelerator pedal and reached approximately 30 miles per hour. The vehicle engine RPM's rose but the vehicle would not accelerate. Placed the vehicle in park and then began driving, where the vehicle appeared as if nothing occurred. This took place around 5/2023 at approximately 26000 miles. On 7/18/2023, the same incident occurred where the vehicle momentarily lost power again and would not accelerate even when the accelerator was depressed. This occurred at approximately 30450 miles. The vehicle then appeared to have no further issues beyond that.
