Water pump has failed at 61, 573 miles. Jeep issued a warranty extension for water pumps in the 2013-2017 models. It appears they have not corrected the defects in their water pumps.

I change my oil religiously on my 2020 Grand Cherokee, which has 67,000 miles on it. I went in today to change it at Bettenhausen Dodge (Bettenhausen Motor Sales Inc - Jeep, 8355 W 159th St, Tinley Park, IL 60477; [XXX] ; Phone: [XXX] ), and [XXX], the service manager manager, told me I had no oil left in my car. He said something went wrong with a pump or something, and as a result I have no engine oil left.. And as a result some engine oil went into the radiator and other places. Plus, [XXX] added, they don't know yet if my engine is damaged as a result. Repairing only what they can see so far (i.e., radiator, pump, hoses etc and that's only if the engine was not damaged, which ostensibly they said they would check before work begins) will cost at least $4700. I asked why no "idiot red light" (as such warning lights used to be called, and such lights have been in every car I have owned since 1972) went on to alert me that there was NO ENGINE OIL LEFT in the car"? The manager said, none of their cars has a "low oil and/or no oil light". All they have is a computer program which informs the driver when to change the oil< and that computer warning system simply is based on miles driven, and it does not inform one if there is no engine oil or low oil. I can not hardly believe there is no red light to tell a person that there is low and/or no engine oil in the car!! The technology behind "idiot red lights" informing the driver of low oil and/or no oil has been around for over 70 years. I am i being lied to? What can I turn for help" INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The check engine light started appearing on the dash and the adaptive cruise control kept appearing that it was off. The light would go off and come on again and the transmission would not shift gears and I could not go in reverse. I drove vehicle to Marino Jeep and they notified me of 3 defects in the internal transmission- which I still have my warranty as the car is at 32.800 miles ONLY on the odometer. This was a dangerous defect causing my car to stall.

Per the dealership: The engine wire harness ws not sitting where it should have been, and was melted by the cadillac converter. This caused the auxiliary battery to fail, and the jump fuse block to blow.

1.The electrical/engine/powertrain systems failed 3 times. The vehicle is available for inspection. 2.As the problem progressed, the car would only go forward, no ability to go in reverse, or to be put in park. 3.The dealership replaced the ABS Module, then later the Engine Control Module. 4.Event 1: September 1, 2022 Warning light for the stop/start feature came on, also the ABS light and check engine light. Dealership kept the car for the day, did a diagnosis, returned the vehicle stating it was safe to drive, and that an ABS Module had been ordered. Would contact me to schedule the repair. Event 2: September 8, 2022 Dashboard lit up like a Christmas tree, all warning lights came on, as well as all lights on the gearshift panel/center console, which kept blinking. Car would only go forward. Dealership installed ABS Module and returned the car to me. Event 3: September 29,2022 Warning light for the stop/start feature and check engine light came on again. I took the car to my local dealership with major concerns that the previous repair was not the only problem occurring and left it there. The Engine Control Module was eventually replaced. 5. I had no use of my Jeep Grand Cherokee from September 29 until November 8, 2022. 6. I have a major concern about the safety of this vehicle.

The vehicle when drive shuts engine off and tell you to shift to park. It has don-??t it to me a few time and twice I almost got rear ended. I took it to the dealer and they say they can-??t find anything wrong with it. To shut off the stop start system but it still does it when I stop start system is off. If you go online a lot of people are having the same issue Jeep just doesn-??t want to acknowledge it. This is very dangerous because it does it at any speed stop and go or you could do 65 on the highway and it does it in jeep is aware of this because many people have complained about it and it-??s going on death years. After some time, the system completely shut off and I was able to drive it without the stop start system. The message that came out was stop start system needs servicing, but the jeep dealer has no idea what that is. They have tested the battery and they said it-??s OK. It Hass to do something on the transmission or something yeah true but this is going to be something if they don-??t fix someone-??s gonna get hurt and when they get a lawsuit that-??s what you-??re gonna do something for the negligence.

Vehicle stalls unexpectedly. Error is "shift to park". Driver shifts the vehicle into park. The car is then locked in park and the driver needs to restart the vehicle. The vehicle doesn't always restart. This has happened multiple times. After the first time, we took it back to the dealership where we bought the vehicle and they replaced the batteries. After the batteries were installed it happened again, took it to a Jeep dealership and they were not able to duplicate the issue so did not do anything. It happened again after that. This is extremely dangerous and can cause serious accidents since the vehicle is stalled in the middle of a road!

Bought jeep in December 2020. Currently at 8000 miles. In October 2021, the vehicle would not turn off. The push button would go between ACC and Start but not in the off. Dealership has never seen this and after 8 days, are not able to definitively tell me what the issue is. The assumption has been given that the car is not recognizing that the vehicle is in Park. This is an assumption as whatever diagnosis that is being done is not finding the error.

Vehicle in motion city & highway. The entire vehicle dies. The engine turns off, all the lights die, no steering, dashboard & radio die. A few seconds later the engine restarts on its own, lights come on, dashboard lights up and radio works. The one remaining issue that indicates the problem is that the radio complete resets to what I believe is the original settings. This problem has been ongoing since the vehicle was acquired. It has been in the dealerships multiple times and they of course can not duplicate so they send me on my way. They have held the Jeep to drive but claim they cannot duplicate. Also there are no codes showing when they check. Try driving at 65 mph with a dead car. Again this has been happening for about a year

The check engine light keeps coming on it has to do with the emissions control the vehicle does not run properly. It has been in the shop 3 times going on number 4 for the same exact problem. I was told that it falls under the lemon law because the emissions control system is defective in that vehicle. My wife was driving the vehicle with our three month old grandchild and the vehicle would not accelerate would not move at all in traffic on a busy highway with vehicles passing by her at 45 to 50 miles an hour.

  • 329 miles
While driving 60 miles per hour along the southbound express lane of garden state parkway my new 2020 Jeep Grand Cherokee started shaking. Within seconds, I pulled on to the grassy area next to the fast lane where my vehicle died. After getting towed to the dealership, I was notified that my new car with 329 miles on it is in need of a new engine, new batteries and new starter. Of notable concern on the repair order is the following: "what is present inside intake manifold is pieces of metal." While the case is not yet closed, Chrysler informed me they intend to fix the vehicle under warranty and return it to me. This is a serious safety concern and I fear the blown engine, dead batteries and starter could have caused additional, unrecognized damage.
