2018 JEEP GRAND CHEROKEE Complaints

Twice I have been driving on the highway at 60 mph and the transmission had suddenly shifted into low gear and subsequently went into limp mode. The dealer is unable to find an issue with the vehicle. There were no warning lights, before, during, or after. After I pulled onto the shoulder of the road and turned the Jeep off and turned it back on it operated normally.

had a recall done in February and 3 weeks later the car would not start randomly no warning lights illuminated on the dash prior to being shut off and once it would start it threw 3 codes for p0850, u0100, and U1267 all related to the parts replaced in February for the recall for the 2nd time now regarding the same parts. and trying to get a reinspection done for the recall bc the parts seem to have failed and its been a living nightmare. and unsure why no warning lights were illuminated prior to the car not starting randomly

Electrical goes crazy when driving and parked , radio comes on, switches from AC to heat , on its own , calls people in my contact list , calls 911, screens goes blank at times , flashes on and off , heated seat on driver side gets way to hot , passenger seat ok so far , headlight keeps going out on passenger side fails to get it off heated seats at times or it freezes, it jumps from defrost to vent to floor , heat to AC , have to turn on AC when it rains to keep windows from fogging up. Hard to drive when it’s lighting up like a Christmas tree , radio won’t stay on same station , jumps from station to station , when on speaker phone it mutes the calls, or hangs up the person you are talking to. Navigation won’t work most of the time freezes up also.

Recall on the hydraulic control unit/anti-lock brake system A brake light incorrectly resulting other drivers not receiving proper indication to stop or slow down which can cause a vehicle crash without prior warning. Call my local dealership and MOPAR and informed me that they still do not have the part to fix this recall. It has been more an an year and half without resolution. They have not inspected my vehicle as I did schedule an appointment but the dealership informed me that they is still no solution and would reach out. There has no warning lamps or messages that appears in my vehicle as of right now.

Check Engine light with Codes: PO300, and PO305. Misfire in Cylinder #5. Changed all spark plugs, and coils. Check engine still on, with same codes. Jeep dealer then said it was the cam shaft and needed new cam shaft head of a price tag of $8500. The car has been well maintained and has 75,200 miles on it. There is a known premature failure with the Pentastar Engine that is in this vehicle. Jeep is refusing to stand behind their product.

The contact owned a 2018 Jeep Grand Cherokee. The contact stated that while unloading groceries out of her vehicle with the vehicle in park(P) and the engine on, grayish-white smoke began to emit from the vehicle without warning. The contact turned off the vehicle and checked under the hood, where she saw flames in the engine. The contact then ran to the fire department, which was nearby, and informed them of the fire. The fire department arrived at the scene with a fire truck and extinguished the fire. The police department also arrived at the scene, and a police report was filed. No injuries were reported due to the fire. The vehicle was destroyed as a result of the fire, but was not towed. The dealer or manufacturer had yet to be notified of the failure. The vehicle was not repaired. The failure mileage was approximately 74,000.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the “Service air Suspension” warning light was illuminated. In addition, the contact stated that the headlights independently turn on and off, the doors independently locked and unlocked, and the radio independently changes stations. In addition, the contact stated that the failure caused the headlights to burn out prematurely. The vehicle was taken to the dealer; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact was later informed that there was moisture in the wires. The contact was informed that the moisture had been cleaned from the wires. The contact was informed that the vehicle was repaired. The contact disagreed with the diagnostic test and the repair. The contact stated that the failure was a known failure with the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000. The VIN was unavailable.

While driving on the highway I received a “SERV 4WD” light and also a traction control unavailable light. Other than that that the car appeared to drive normally other than I could feel the car gears “catching” at starts when I pressed the accelerator. I took the car to the certified dealer and they said it was a transfer case failure and was unsafe to drive as it could have caused the wheels to lock up. This issue is very similar to a recall for other Jeep VINs over the same production timeframe of my Jeep, although my VIN was not included in that recall. I am seeking the immediate inclusion of my VIN into the Jeep recall that exists for manufacturing defects of the transfer case.

1. The issue involved the engine and emissions system, specifically a cylinder 3 misfire, accompanied by illumination of the check engine light and white smoke emitted from the exhaust. The vehicle was evaluated by an authorized Jeep dealership, which confirmed the cylinder misfire through diagnostic testing. At that time, per the diagnosis, coil 3 and all spark plugs were exchanged. This did not solve the issue. When picking up the car, check engine light was still illuminated and white smoke emitted from the exhaust. The affected components are in possession of the dealership, unsure if available upon request. 2. The engine misfire and associated white exhaust smoke created a risk of engine performance degradation, including potential loss of power, observed hesitation and stalling, which could impact the ability to safely operate the vehicle in traffic. Additionally, white smoke from the exhaust can impair visibility for surrounding drivers and may indicate an underlying engine condition that could worsen without warning, increasing the risk to the driver and others sharing the roadway. The chemical smell could also nauseate the person operating their vehicle, impeding their awareness and concentration. 3. This issue was proposed by an authorized Jeep dealership, then confirmed by two other mechanics. Dealer diagnostic records document the cylinder 3 misfire and investigation related to the check engine light and exhaust condition. 4. No inspection from manufacturer, police, or insurance representative. 5. Yes, the check engine light illuminated and the vehicle exhibited white smoke from the exhaust which prompted the service visit. Auto-start was not functioning as normal, with an error displayed on screen. Engine would sometimes stall upon start up during cold temperature days. NOTE: vehicle is currently with another mechanic awaiting an engine replacement, will upload that invoice once available.
