2018 JEEP GRAND CHEROKEE Complaints

The contact owns a 2018 Jeep Grand Cherokee. The contact received notifications of NHTSA Campaign Numbers: 22V406000 (Fuel System, Diesel) and 24V838000 (Service Brakes, Hydraulic); however, the parts to do the recall repairs were unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repairs. The dealer was contacted and confirmed that parts were not yet available. The manufacturer was not made aware of the issues. The contact had not experienced a failure.

The vehicle experienced a failure of the engine lifters/rocker arms, which also caused failure of the intake camshaft. This resulted in severe misfires, loss of power, and left the vehicle completely inoperable. The failure created a hazardous situation when the vehicle lost acceleration and was unable to maintain safe driving speeds, placing my safety and the safety of others at risk of collision. The problem was confirmed by Lou’s Car Care and multiple Stellantis dealerships, including Maguire Chrysler Dodge Jeep Ram. All inspections identified failed rocker arms/lifters and the intake camshaft as the cause of the malfunction. Critically, Stellantis no longer produces replacement intake camshafts for this engine, and the part is listed as indefinitely back ordered and unavailable. This means there is no factory fix, leaving the vehicle permanently disabled. Prior to the failure, the only symptom was a faint ticking noise from the engine. No warning lights or dashboard messages appeared before the incident. The problem escalated suddenly without adequate warning, causing the vehicle to lose power unexpectedly. This failure has caused severe negative consequences for me and my family. Because the vehicle became inoperable and the repair could not be completed, I lost my job due to lack of reliable transportation. I also experienced financial hardship, including losing my vehicle to repossession. My family, including my newborn child, was left without dependable transportation, which created additional safety concerns in emergencies. The failed components remain available for inspection upon request. This issue is widespread across Stellantis vehicles yet has not been addressed through a recall, despite the fact that the defect can cause sudden stalling or total engine failure at unsafe speeds. The unavailability of replacement camshafts means affected vehicles cannot be repaired at all, leaving owners stranded and financially devastated.

Since the beginning of this year, vehicle began to misfire. So far I have spent over $2000 in repairs including replacing spark plugs, ignition coils, fuel injectors and oil cooler and vehicle continues to misfire and blow white smoke from exhaust. I have been advised that it may be a head gasket issue, which could cost anywhere from $3000 to $5000 but could cost more in the event the engine needs to be completely replaced.

My 2018 Jeep Grand Cherokee Overland is experiencing serious electrical malfunctions related to the Uconnect radio head unit. This component appears to control or influence multiple vehicle systems beyond just audio, including climate control, backup camera, navigation, and possibly driver assistance features. The system malfunctions frequently and erratically — settings change on their own, the screen goes black or freezes, and controls become unresponsive while driving. These distractions create a serious safety hazard, as I am forced to take my attention off the road to regain control of basic functions like defrost or audio volume. I have discovered that this issue is widely reported by thousands of Jeep owners from this model year and earlier, particularly those with Uconnect systems. Jeep has refused to address or recall the problem despite it clearly impacting driving safety and vehicle usability. This malfunction significantly impairs my ability to operate the vehicle safely. I respectfully request that NHTSA investigate this issue as a potential safety defect. I have taken my car to the dealership and was advised that the whole radio unit needs to be completely replace. I have contacted Jeep and inquired about it, they told me they are aware of the issue but at this time, unless the car is under warranty, they do not offer any financial assistance. And it is a rather expensive issue to fix considering there is no fault of the car owners that the items installed in their vehicles are faulty.

The RPM lowered and the vehicle failed to respond while depressing the accelerator pedal. There was no warning light illuminated. The failure persisted, and the contact coasted into a parking lot and there was an excessive amount of yellow-grayish smoke coming from the engine compartment. The contact exited the vehicle and became aware of an unknown liquid pouring onto the ground underneath the vehicle, with little pieces of debris and sparks igniting underneath the vehicle. While the contact was on the phone with 9-1-1 Emergency Services, there was a popping sound coming from the vehicle and underneath the hood and over the windshield became engulfed in flames. The Fire Department arrived at the scene and extinguished the fire. A fire report was filed.

Rockers & cam shaft are worn and making ticking noise. I only have 86k on my 2018 Jeep Grand Cherokee, and am diligent with upkeep on the maintenance. This is a very known issue and should be recalled as I have not driven it anymore to prevent further damage to the engine, and also don't have the funds to fork out almost 5k.

I own a 2018 Jeep Grand Cherokee with the Uconnect 8.4" touchscreen. The screen has begun to delaminate—a well-documented and widespread issue in 2017–2019 Jeep models. As the touchscreen separates from the display, it causes ghost inputs and malfunctions in key systems: - The radio and Apple CarPlay are unusable - The screen randomly calls contacts, including emergency services like 911 without my consent - I’ve had to disable Bluetooth on my phone to prevent unintended calls and inputs - The issue prevents safe and legal use of my Drive Safe & Save Bluetooth beacon from my insurance company Multiple Jeep dealerships quoted between $1,000–$2,000 for repairs, despite this being a known defect. The vehicle is out of warranty, but this malfunction poses a safety hazard. I am filing this complaint to request that NHTSA investigate this issue and encourage Jeep/Stellantis to issue a recall or extended warranty coverage. This issue is not cosmetic—it compromises driver focus, emergency call systems, and critical controls. Many owners are experiencing the same failure with no accountability from the manufacturer.

I have been without a vehicle for over 5 months. Paying on a vehicle that I cannot even get out of the garage. Paying storage insurance on a vehicle. There is a major issue with camshafts right now. I have had the spark plugs changed, coils, oil and I was waiting on the camshaft which is on back order for who knows how long. This needs to be addressed and recalled. With the amount being over 14,000 parts on back order I think this should be recalled. Even people who have had the camshaft fixed are still having engine issues with the 3.6L. Please do something about this, I have put so much money into this and I need a vehicle. At 75,000 miles this should not be happening.
