2020 Jeep Grand Cherokee Problems

2020 Jeep Grand Cherokee problems owners report most

2020 Jeep Grand Cherokee problems are documented in public: owners have filed 240 complaints with NHTSA, the earliest in 2019 and the most recent in 2026. Sorting those by the component the filer named puts the electrical system clearly first, at 73 of the 240 complaints, close to a third of everything filed.

A complaint is not a repair bill and not a defect finding. It is one owner telling the regulator something went wrong. What makes the count useful is the concentration: when one component takes 30 per cent of everything filed on a car, the pattern is doing more than chance.

Against the 2019 car, this model year has drawn 35 per cent fewer complaints (240 against 370). The 2019 car was led by its brakes instead, so the pattern shifted between the two years.

Of those complaints, 24 describe a crash and 5 describe a fire. Filers reported 13 injuries.

Recalls on the 2020 Jeep Grand Cherokee

A recall means the manufacturer or the regulator found a safety defect, and the repair is free at a franchised dealer however old the car is. There are 3 recalls on this model year. Your own car may be covered by some, all or none of them, so check the VIN rather than the model.

In owners own words

These are complaints filed about the electrical system, quoted as written. They are one persons account rather than a diagnosis, and they are here because a symptom described by a driver is easier to recognise than a component name.

About 3 years ago i noticed a small bubble in the upper right corner of my touchscreen. Didnt pay much attention for a while but it started spreading to the left. I took a photo and sent a picture to the man that helped me buy my car and asked if there was a known Recall for this. Said he would check, he confirmed there was none. I let it go because i hadnt purchased any extended warranty. Bubbling continued to spread. Occasionally my radio station would change on its own. I thought it was just my imagination and let it go. In July of 2025 my family and i were on vacation and I was driving in

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 in

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 volt

How other model years compare

The same nameplate across the years we hold. Complaint counts fall naturally for newer cars because fewer of them have been on the road for long, so read the column as a rough signal rather than a ranking. In this set the 2018 Jeep Grand Cherokee has drawn the most complaints and the 2020 Jeep Grand Cherokee the fewest.

What to check on the electrical system

Electrical reports cover a wide spread: screens that reboot, cameras that go black, charging that stops, and warning lights that arrive in groups. The common thread is that the fault comes and goes, which makes it hard to show a mechanic on demand.

Buying a used 2020 Grand Cherokee

Sit in the car with the engine running and work through every switch, screen and camera before you talk about price. An intermittent fault that appears once during a ten minute check is likely to appear often once you own it.

If you already own one

Have the battery and charging system tested before replacing any module. A weak battery produces electrical faults that look like a dozen separate failures, and the test is free at most parts retailers.

• Test every screen, camera and switch before agreeing a price.
• Have the battery and alternator tested before replacing a module.
• Ask for stored fault codes, including the ones already cleared.
• Check whether the fault is covered by a software update.
