2020 Jeep Grand Cherokee driver assistance problems

Filed Sep 20, 2026 · Brakes, Driver assistance · MI

ABS module completely malfunctioned from a shortage. Threw up 7 different codes, even threw up my check engine light for a bit. Can’t even use cruise control because my “memory system” and “park sense” are unavailable. Sometimes it makes the wheel super stiff and the acceleration and break pedals super sticky. I see many recalls for 2020 Jeep Grand Cherokee’s, and believe mine should be included. I should’ve have to pay $3,000 out of pocket for something a ton of people are reporting as an issue. I found one reported a few months back with the same issue.

RE: SAFETY RECALL W36 (the federal safety agency ID 20V‑191). Manufacturer Stellantis (FCA US LLC) has reported this safety recall as "Complete" for my VIN. This reporting is inaccurate. The vehicle remains on firmware version 30.21.0, which is the defective version the recall was mandated to replace. The Head Unit and Telematics Box (TBM) hardware are failing to accept the required safety patch. Stellantis Case Management (Case #95948441) has refused to provide the mandated free remedy and is demanding a consumer-paid diagnostic fee to address this failed safety recall, in direct violation of 49 U.S.C. § 30120. Furthermore, the dashboard assembly is failing (adhesive degradation), causing significant rattle/distraction. The manufacturer refuses to honor the Federal Safety Act and remediate these defects without charge. I have already performed the diagnosis and provided firmware evidence which the manufacturer has ignored.

On September 15–16, 2025, my vehicle was serviced at AutoNation CDJR North Columbus, where the technician documented: “Oil filter housing failed internally.” •No repair, replacement, or warning was provided to me about the risk of catastrophic engine failure. •I was not presented a signed repair decline form. •Internal failure was documented but not escalated. On February 13, 2026, the engine failed completely, rendering the vehicle inoperable. The dealership quoted ~$13,094.83 for engine replacement but did not authorize repair. During this time, oil and coolant leaks were observed, indicating continued mechanical risk and potential safety hazards.

My 2020 Jeep Grand Cherokee touch screen is delaminating. I have attempted to contact uConnect and Jeep. UConnect initially agreed to replace the screen free of charge after having it diagnosed, but once I had it diagnosed and called back uConnect claimed the first representative that approved the replacement was wrong and now refuses to rectify the situation. The screen has "ghost" touches - basically selecting options by itself, and the back up camera delays or freezes some of the time, not displaying the live video. The dealer diagnosed the delamination. There were no warnings or other indications of a problem. I only learned what was causing these issues by googling the bubbles in my screen. Based on the research I've done since, it appears this problem will get worse, changing climate control settings, system settings, heater settings, entertainment (radio) settings, and "drive mode" type settings eventually. I have seen so many posts on it spanning multiple models and model years, all related to the same problem with the same symptoms, it should really qualify for a recall. I am afraid to let my soon-to-be 16 yr old drive my car because of the distraction this defect can cause, and there is no prevention or reasonable remedy. The screen has not been intentionally damaged, no wipes or other products have been used on it regularly, and it is kept garaged when it is not being driven. The vehicle is used in a normal manner -driving to/from work and practice on city streets and highways, and is not subject to abuse. From my research it is a manufacturer's defect in the screen itself, which can only be avoided or resolved by replacing the unit. If owners don't cause the issue, and can't prevent it by any kind of regular maintenance, training, or care, then it isn't an issue owners should suffer safety concerns or financial obligations over.

I am reporting significant safety issues with my 2020 Jeep Grand Cherokee Limited X. The vehicle has repeatedly experienced failures in critical safety systems such as Adaptive Cruise Control (ACC), ParkSense, and Lane Departure, which randomly disable while driving, particularly in cold weather or after a restart. These failures compromise essential safety functions necessary for highway driving and parking. Additionally, I encountered a severe issue regarding the vehicle’s lack of over-voltage protection. While charging the battery, it was accidentally exposed to 48 volts instead of 12 volts, resulting in damage to key electronic modules, including those controlling safety systems. This lack of protection from foreseeable charging errors is concerning, especially given the advanced electronics in modern vehicles. Other Jeep owners have reported similar issues related to voltage fluctuations affecting ACC, Lane Departure, and ParkSense systems. Battery-related issues seem to be directly linked to the failure of these critical safety features​(Jeep Cherokee Club)​(Jeep Forum). Voltage instability, particularly with the Engine Stop/Start (ESS) system, has also been widely discussed, further pointing to potential flaws in Jeep’s electrical design. Given the critical nature of these systems, their failures due to inadequate over-voltage protection and inconsistent electrical performance represent a serious safety risk. I request that the federal safety agency investigate these concerns, as they may be affecting a broader range of Jeep vehicles, putting drivers and passengers at risk. While a fire did not occur, the potential is there due to the burning of electronics with strong odors and smoke.

Purchased used 2020 Grand Cherokee at Christmas time 2023. Vehicle had 25640 miles on it. On April 24, 2024 while driving home maybe 2 miles from home, I was lucky not to crash when losing steering response.A Warning Message appeared on the Speedo, stating, “POWER STEERING UNAVAILABLE SERVICE REQUIRED “. 28K miles is about 2,400 miles driven to date. I drove straight home and made an appointment for service. Koons Chevrolet where I bought the car performed diagnostic testing to determine Replacement of the Steering Gear RACK AND PINION would require replacement and the repair $5800 parts and labor. The module is internal and not serviceable therefore the Whole Steering Gear must be replaced. Cost is prohibitive for a fairly new vehicle.

My Jeep is a 2020, and I recently bought it last June as a certified preowned vehicle from a Jeep dealership. I was having electrical and fuse problems when my moon roof on the vehicle stopped working. Recently driving home at night, I lost all lights on the vehicle. Headlight, high beams, brake lights and turn signals, the lights do not work on the vehicle and I was driving in the complete dark. My gas tank also was having issues and it does not allow me to fill the tank because it thinks it is always “full” even though it is not. I brought the vehicle to the dealership and they stayed I have a completely fried computer system as well as the vent tube on my gas tank is “clogged” and the entire gas tank needs to be replaced. I have owned the car for less than a year and a half, it is only three years old and the warranty JUST expired. There is no way a vehicle with only 32,000 miles has a completely failed computer system along with needs a full gas tank replacement. They are stating to fix the safety issue it is $2700. The manufacturer is taking zero responsibility. Roughly 6 months before I took it to them because I was having fuse issues.
