2017 Jeep Grand Cherokee: engine failure

Filed Aug 19, 2026 · Engine, Transmission · MA

On November 23, 2025, I was driving approximately 60 mph in the middle lane of I-495 near Exit 62 in Marlborough, Massachusetts, with a passenger in the vehicle. I signaled to change lanes to pass a slower vehicle, selected Sport Mode, and accelerated. The engine RPM increased sharply and, almost immediately, I heard an extremely loud bang from the engine area. Multiple warning lights began flashing on the instrument panel, the vehicle made abnormal noises, and the engine lost power. The loss of propulsion was immediate while I was traveling at highway speed. Because that section of I-495 slopes slightly downhill and I was already close to Exit 62, the vehicle's momentum allowed me to reach the exit and pull onto the shoulder. Had this occurred in heavier traffic or in a location without a safe shoulder or exit nearby, the sudden loss of propulsion could have resulted in a collision. The vehicle became inoperable and required towing. It was later inspected by an authorized Jeep dealership. The dealer documented a hole in the side of the engine with engine fluid leaking out and determined that the engine requires replacement. The vehicle had approximately 94,298 miles at the time of the incident and had been regularly maintained. The same vehicle had previously experienced a significant engine problem in 2023 at approximately 67,987 miles, involving white smoke, a head gasket leak affecting cylinder 5, and replacement of the cylinder head. I am reporting this because the catastrophic engine failure caused a sudden and complete loss of propulsion at highway speed. The vehicle and failed engine remain available for inspection.

I was taking my daughter to school and we were stopped at a light when the check engine light came on. When the light turned green and I pressed the gas the vehicle didn’t seem to respond at all and I rolled my car at the right turn and parked it. I turned it off and back on and it was still doing the same thing. I had someone pick up my daughter and take her to school. I started scheduling a tow but after it sat for a while it was able to drive to a shop for inspection where they tested it and received the error code: P076F = Gear 7 incorrect ratio. I was told the entire engine needs to be replaced. The vehicle has low mileage. Our safety was at risk because I had no warning to get the car to the shop before a major malfunction. I was very fortunate my car was stopped at the time. If I was waiting at a left turn in an intersection we could have had a terrible collision. The exact problem has not been reproduced. The vehicle has not yet been inspected by the manufacturer.

2017 Jeep grand Cherokee, 103k miles. I purchased my car new for around $45,000. All maintenance was done on time. Oil cooler assembly went out, then head gaskets, now I need a new engine. At 103k miles !Jeep has done nothing other than tell me sorry that will be $15,000 to repair. My engine is doing that loud clicking sound everyone is talking about. I’ve spoken with countless people this has happened to, some as early as 49k miles. There are videos online of mechanics bragging about how much money these engines are making them in repairs. Yet Stellantis still refuses to take responsibility for their 3.6L Pentastar V6 engine issues. Even though there is a current class action against them for it. There are full YouTube videos from mechanics explaining exactly why the 3.6L Pentastar V6 engine fails and still Stellantis chooses to take more money from consumers to fix/replace their faulty engine. Now onto functionality of my vehicle, the start/stop engine problems I see people complaining about on here are real. The first thing I did when I got into my car was turn OFF my start/stop system. 20% of the time my system worked properly when left on. The rest of the time it was dangerous. The car would shut off when hitting the breaks and stall. I would be stuck on the freeway having to restart my car. I’m lucky it never caused an accident but it is terrifying being in the middle of the street and your car just shutting off and engaging the parking break and stuck in neutral. It’s happened more times than I can count, stop lights were where my car shut off most commonly. Usually would result in cars honking and people screaming to get out of the way while I scramble to get my car to turn back on. Over all, I’m so disappointed in this company and how it chooses to treat its consumers.. I was forever a Jeep owner until this week.

THE 2014 - 2017 Jeep grand cherokee as well as many other chrysler mad 3.6lL v engines are all either past their standard warranty period or are approaching it. The problem i have specifically is that my car has under 50 k miles and i have a receipt showing it was bought in november of 2017, there for still under Jeeps powertrain warranty, and the headgasket is failing. ive been to multiple accredited mechanics before taking the vehicle to jeep how performed all the necessary test to concludits the gasket needs to be replaced. i then took it to a dealership who said " On thes 3.6L engines it extremely common for this to happen." i was then quoted 3k for the repair and dropped my car off. after 2 weeks of them having my car and me calling daily for updates i was finally told the car needs a new motor. which would cost 11k. I denied and called chrysler claims department who told me its out of warranty and I would have to pay out of pocket for the repairs before they would look into "how much they might be able to reimburse me" after searching online I've noticed this is a huge problem for many people. it seems as though Chrysler made an engine that will last 50 k miles and then have catastrophic engine failures. you might timed obsolescence. any way i hope this issue is looked into because this company, Chrysler is putting thousands of middle class Americans out of a vehicle or potentially into debt. hope to hear back soon [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
