2018 Jeep Grand Cherokee problems owners report most
2018 Jeep Grand Cherokee problems are documented in public: owners have filed 855 complaints with NHTSA, the earliest in 2017 and the most recent in 2026. Sorting those by the component the filer named puts the electrical system clearly first, at 339 of the 855 complaints, two of every five 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 40 per cent of everything filed on a car, the pattern is doing more than chance.
| Component | Complaints | Share |
|---|---|---|
| ELECTRICAL SYSTEM | 339 | 40% |
| UNKNOWN OR OTHER | 267 | 31% |
| ENGINE | 125 | 15% |
| POWER TRAIN | 75 | 9% |
| SERVICE BRAKES | 63 | 7% |
| FUEL/PROPULSION SYSTEM | 44 | 5% |
Against the 2017 car, this model year has drawn 135 per cent more complaints (855 against 364). The 2017 car was led by its engine instead, so the pattern shifted between the two years. A rise is worth more attention than a fall here, because a newer car has had fewer years on the road to accumulate reports.
Of those complaints, 42 describe a crash and 10 describe a fire. Filers reported 33 injuries.
Recalls on the 2018 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 11 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.
Chrysler (FCA US LLC) is recalling certain 2018 Dodge Charger, Durango and Challenger, Jeep Grand Cherokee and Wrangler, Chrysler 300, and RAM 1500 vehicles. An incorrect transmission park lock rod may have been installed in the transmission.
The risk. If the incorrect park lock rod is installed, the transmission may not shift into 'PARK' and keep the vehicle from moving, increasing the risk of unintended vehicle movement and the risk of a crash.
The fix. Chrysler will notify owners, and dealers will install the correct park lock rod, free of charge. The recall began June 28, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U43.
Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles.

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.
Urgent Safety Concern Regarding Defective Uconnect Radio System Shortly after purchasing my vehicle from Bertera in Westfield, Massachusetts, I began experiencing issues with the radio and related components—namely, erratic or "ghost" activity. I returned the vehicle to the dealership on multiple occasions; however, because the issue failed to replicate while in their possession, they were unable to offer any resolution. The problem persisted intermittently, but escalated significantly during a visit to Logan Airport. While curbside, the vehicle began behaving erratically: the exterior lights
The 2018 grand Cherokee has issues with mother board and electrical ghosts. 1st it was headlights and dome lights. they would flicker. i had to change the front lights 2x in a year. i thought this was odd. never did this with any car before. then I was driving home from work during rush hour and it started to rain. started the wipers front and back. the back wiper started and went halfway and got stuck. what happen? the front wipers went on for several revolutions (say 10-20 ) then stopped. started again. then stopped again. the rain intensity grew. Now the -wipers would only wor
My 2018 Jeep GC has the delaminating screen It has 88,000 miles & I was told since I am not the first owner it’s not going to be fixed. Hard to believe I paid $30,000 for a vehicle with everything to be reduced to having nothing. The screen gets very hot & sticky stuff melts onto the console!! Once a screen comes up about clock settings then nothing can be accessed. The preset radio stations randomly & constantly change, the temperature goes from hot to cold, it switches from xm to regular radio, it saves favorite songs & artists, seat warmer comes on & you cannot turn it off or down, when st
Subject: 2018 Jeep Grand Cherokee – Sudden Loss of Power, PCM Failure, Electrical Failures, and Concern Regarding Recall-Related Symptoms I am filing this complaint because my 2018 Jeep Grand Cherokee experienced a sudden and unexpected loss of power while I was driving, and I am very concerned about the safety implications and the possible connection to the recall-related electrical problems associated with this vehicle. Before the final failure, my Jeep had been experiencing electrical and starting problems. The alternator failed, the batteries went bad, and I had already paid for multiple
Touchscreen interface (8.4" Uconnect) is delaminating and causing ghost touches which randomly select and activate systems on the screen, including switching screens to different controlled systems. While some of these may not be considered safety-related (environmental controls), I would respectfully suggest that others are, including: random and unexpected changing, turning on or off radio various audio at various sound levels (imagine turning on your car and somebody jokingly set the radio to an extremely loud volume - funny, but not necessarily unsafe. Now imagine that happens randomly wh
My UConnect radio has been malfunctioning for a few months now. I've seen this on Jeep forums being a major issue with 2018 jeeps. My radio stations would randomly change while driving. The volume know would stop working, my Navigation stopped working and would place my location in a completely different state. Last week, while driving my UConnect would randomly turn on the AC and then switch to heat and then turn it off, and then switch between modules. The Sunday after Thanksgiving, I was driving my parents to the airport using the GPS on my phone but connecting it to Apple Car Play so that

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 2018 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.
