general problems of the 2015 Jeep Grand Cherokee - part 1

Sudden unintended acceleration while braking. Engine revved against brake input. Has happened multiple times. Need to step on the brake hard and wait for it to pass.

While driving, engine immediately shuts off. Dash, radio, lights, etc. All function as normal. Dash cluster shows an error message, saying to shift into park. After parking vehicle on shoulder, engine turns over but does not restart after several attempts. After awhile, engine finally restarts. No error codes or messages are displayed. Scanning with an obd device shows no stored or pending error codes. Vehicle now operates normally. This has happened twice in the span of two weeks, and never previously.

Vehicle began displaying check engine light. Diagnostic code p219b (bank 2 air-fuel ratio imbalance) was identified. Vehicle was serviced and a valve-related repair was performed. Shortly after, engine performance worsened and further inspection revealed metal shavings in engine oil and confirmed internal lifter/valvetrain failure. Oil levels were normal and maintenance records are available. No warning of low oil pressure or overheating occurred prior to failure. Independent service center and inspector confirmed internal mechanical failure. Engine failure created risk of sudden loss of power while driving. This appears consistent with documented pentastar 3. 6l valvetrain/lifter issues reported by other owners. Concern is potential for sudden engine malfunction and safety risk due to power loss.

Check engine light came on and when we had it tested with the obd?ii scanner it came back with a fuel system wiring harness corrosion emission control module software updates transmission shift issues.

My engine oil is mixing into my coolant jug and radiator replaced the oil cooler housing and the issue still continues.

While driving at highway speed, the vehicle suddenly lost power, displayed a low oil pressure warning, and became inoperable. The vehicle had to be towed. Dealer initially claimed “overfilled oil,” but an independent oil analysis (blackstone labs) confirmed excessive fuel dilution (5. 5%), indicating contamination of the oil system. This vehicle is covered by NHTSA recalls 22v-406 (fca z46) and 23v-263 (fca 01a) related to premature failure of the bosch cp4 high-pressure fuel pump. Recall documents state: “a hpfp failure may introduce internally failed component debris into the fuel system potentially causing fuel starvation. Fuel starvation may result in an unexpected loss of motive power, which can cause a vehicle to crash without prior warning. ” the vehicle’s failure aligns with this description. Dealer has not yet performed an hpfp inspection despite recall requirements. Request: NHTSA investigate whether fuel dilution and catastrophic failure are linked to the cp4 hpfp defect covered by these recalls.

Had to have repairs done after two weeks of purchase of vehicle for recall for vehicle losing power when picking up speed also engine light is on continuously. Contacted dealer and requested repairs dealer was non-compliance. I had to pay for repairs myself. Still having issues and engine light still on. Contacted dealership and requested reimbursement for repairs 5 months ago haven't been reimbursed yet. What can I do. Spent $1400 for repairs.

Needs rocker arms, valve lifters and camshafts replaced.

The traction control light comes on while driving, once that happens it changes the performance of the vehicle it stays in one and it doesn’t allow you to do more then 43 at the most.

Lifters are ticking. Yet another 3. 6l pentastar engine with the same issue, and no recall issued. Someone is going to die from this defect, if there haven't already been fatalities related to this problem.

I was crossing a road to get to the median and my Jeep stopped moving in the middle of a 4 lane highway, separated by a median that I never made it to due to it stopping moving during acceleration. It made noise when I pressed on the gas pedal but didn’t go anywhere. I was hit by a car that couldn’t avoid me, and my daughter and I were injured in the crash. My daughter had a fracture in her right leg & facial bruising. I had a laceration requiring stitches and facial bruising, lost consciousness at the scene and am severely concussed.

The engine overheated due a coolant leak causing head gasket failure. The engine will now most likely need to be replaced. The engine is 3. 0 ecodeiesel which was part of the fca settlement . There were no warning signs. Engine overheated with dealership while getting the fuel tank pump replaced. Dealer confirmed issue.

I have owned this vehicle for 9 years and the vehicle has had an issue with the electronic fuel pump since I bought it. I would take pictures of the warning showing the error message. I have had the vehicle in the shop more than 10 times for the same symptoms and begged them to replace what the computer is saying was the problem. I have spent over $9,000 on repairs and I continue to get the same message, the check engine light is on continuously and every time I bring it in they say it is not that it is something else and they replace something not related. Then the recall came out for the high pressure fuel pump which was apparently the issue for the entire time like the on board computer had been stating was the issue. I have replaced the thermostat when there was no over heating issue, the alternator when there was no electrical issue, the particulate filter because they said that was what was causing it to go into crawl mode which it still does periodically when it rains out. The recall was issued on 6/9/2022 and it is still not repaired. There is no telling what other internal damage was done over the 9 years of not replacing what was the issue the entire time.

When stopping and suddenly accelrating Jeep has a power delay and you have to hit the throttle agressively to get going or else I run the risk of getting hit by another car, but once you hit throttle the power is more than you need it or expected it, forcing me to brake or else I hit the pcar infront of me. I am still not able to make this work. I purchased the car used, I am still making payments and I barely use it because I find it extremely dangerous at time. The power doesnt come when I need it but when I do its too much, feels like I floored it and I have managed not to crash but its something someone should take a look at before its too late.

While driving on the freeway, I heard a quiet noise but saw no warning messages on the dash. I decided to pull over and found the vehicle had shifted into neutral and lost power steering. The vehicle was towed to a aaa service center. They discovered that the safety recall w79 / NHTSA 20v-699 diesel ecr cooler had been replaced but failed again, requiring a complete engine replacement. The recall was repaired in may 2022, and the part failed in July 2024, two months outside the warranty. The dealer where we bought the vehicle and had the recall serviced won't return my calls.

The engine kicks like the injectors are blocked or something. It happens in idle and all speeds, including highway speeds. It is not speed related. However, I am reporting this because it jerks the car at highway speeds and this is dangerous. I have one occurring trouble light regarding the oil pump but it’s not related. Something is troubling this engine like there is debris in the fuel line but all of my recalls have been fulfilled.

Purchased a 2015 Jeep Grand Cherokee. At around 65k miles vehicle started making a ticking sound. Vehicle was also stalling when accelerating from a stop, usually when making a right turn but also when trying to press gas to gain speed quickly like when entering the highway. There is a known issue with this model where the rocker arm fails and damages the cam shaft. Engine light went on so contacted the dealer and brought the car in for a recall repair. I drove out of the dealership and the engine light went back on. Brought the Jeep back and was told engine issue wasn’t covered under warranty and repairs would cost $5k. I’m contacting the dmv automotive facilities inspector to file a complaint on the dealership and will be contacting a lawyer regarding a class action lawsuit unless I get a resolution to this issue. I drive my 3 small children around every day in this car.

Th cylinder has low compression causing misfire in the vehicle. The misfire can cause the vehicle to lose power. If you lose power on a highway it could cause an accident. This has not happened to me, but I have read the cyinder issue is a common problem with the 2015 Jeep Grand Cherokee seems like bad parts. A mechanic has ascertained the problem with my vehicle. If this is a common problem why has the manufacturer not fixed the problem and inspected these parts?.

Driving on highway 290 west near waller. At 75mph I attempted to pass slower traffic by accelerating after moving into the farthest left (passing) lane when my Jeep lost power. Had to maneuver while coasting between traffic in lanes (frogger anyone?) to farthest right lane by coasting through to an exit by chance. Would not restart while coasting. Traffic line formed behind me for those also seeking same exit I needed at the last second. I was unable to fully move into shoulder because of debris seen and fear of damage to tires. After coasting to a full stop a quarter mile from love's truckstop, put vehicle in park, and was able to restart after hesitation. Engine light on with my reader stating "confirmed" codes p0336, u1401; and a "pending" code of p05ed. Now takes 3-5 seconds to start when used to be "instantly. " in a nutshell, this was not fun. :| note to manufacturer , please stop skimping out on quality.

I have been trying to get this recall fixed for over two years not. I have received over four notices from fca via us mail. Each time I go to the dealer, planet Jeep, in flagstaff, az I am told that there are no parts available and they cannot do anything. The first three times I was told that I would be put on waiting list however when I checked last week they said there is no record of me even commig in for it. I tried to call fca directly on the phone number listed to call for help with the recall. The fca rep said all I need to do is go into the dealer to get it fixed. I explained to her the issue and she put me on hold and called dealer directly. The dealer at planet Jeep stated same thing, there are no parts available and I would be put on a list. I asked fca if I could escalate this and she said there is no recourse for recall issues. I want to sell my Jeep however no one will purchase when I disclose the missing recall which is the high pressure fuels system and very serious as there have been issues of vehicles stalling on the freeway speeds and causing accidents. I think two years and several attempts to fix this is unreasonable. I am requesting your assistance.
