2014 Jeep Grand Cherokee: engine failure

Filed Jul 9, 2026 · Engine, Fuel system · MI

My 2014 Jeep Grand Cherokee suffered a total intake manifold failure directly resulting from a secondary breakdown of Safety Recall W79 (the federal safety agency Campaign 20V‑699). Physical teardown at an independent facility exposed a 70% engine runner restriction and seized glow plugs due to volatile exhaust sulfur, creating an active fire risk. On July 9, 2026, LaFontaine Fenton was presented with clear mechanical photos and a continuous 2023 dealer repair loop under Customer ID [XXX], but formally refused to open a corporate STAR Case or dispatch flatbed transport to remedy this active safety defect.

My 2014 Jeep Grand Cherokee Summit EcoDiesel (VIN: [XXX] ) experienced a catastrophic engine failure at approximately 116,000 miles while driving. The vehicle suddenly displayed an oil pressure warning, and I immediately shut the engine down to avoid further damage and potential safety risks. At the time I shut the engine off, the engine was not making catastrophic knocking noises and was not leaking oil heavily. The vehicle was towed to Astorg Dodge Chrysler Jeep in Parkersburg, WV. Before inspection, I specifically instructed dealership personnel not to start the engine because I suspected a serious oil-related issue and wanted to avoid causing additional damage. Despite these instructions, the dealership started and ran the engine anyway. After the dealership started the vehicle, the engine condition reportedly worsened significantly, including severe engine noises and much heavier oil leakage. I was later informed the vehicle would require complete engine replacement, with estimated repair costs ranging from approximately $10,000 to $24,000. At the time of failure, the vehicle was also subject to the unresolved Z46 High Pressure Fuel Pump (HPFP) recall, which had not yet been completed. I had previously been informed that recall parts were available and the repair would be scheduled. I am concerned that the unresolved recall and/or related fuel system issues may have contributed to this catastrophic engine failure. I am also concerned about the potential safety risk associated with sudden oil pressure loss and catastrophic engine damage while operating the vehicle. I am submitting this complaint so the failure and unresolved recall involvement are documented and reviewed.

Vechicle returns to limp mode. Almost causing several accidents on interstate. Engine 3.6. variable valve timing enough jeep at one time offered a longer warranty. Replaced cams,heads,phasers,oil pump,computer,timing chain,timing gears, over 9000.00 parts and labor. Mopar parts very problematic with the varible timing valve train.after problems in timing was fixed, there now is a oil pressure problem. Master mechanic credentials worked on vechicle several time and hour to try to fix problems. Mechanic now say only way to make vechicle safe at this point is to put a new engine in.this will cost over 13000 dollars over the 9000.00. I have already spent. Scariest part of this vechicle is when on a 70mph interstate and vechicle goes to a top speed of 40mph.

Known issue with engine design that could lead to catastrophic failure. The rocker arms fail and gouge the cam, causing catastrophic engine failure, if not addressed as soon as symptoms occur. We caught the knocking noise early and were able to have both sides replaced for $3800 on a vehicle with relatively low miles. This has been a noticed issue and to my knowledge, the replacement parts were redesigned to correct the issue.

Jeep customer care said my jeep was imported from Canada and is void of any and all parts warranty. So that's why dealership couldn't register my jeeps engine warranty.

I own a 2014 Jeep Grand Cherokee 5,7 summit trim, I've been experienced a very scary situation with this car on last 4 months, with no warnings this vehicle completely shuts-off, with no power, no radio, no dash lights. For few times happened on my drive way, but most the times I was on highway running between 45 to 70 mph, its come from the blue. But after the engine stops, it just restart like nothing had happened, no lights on dash no warnings. I left this truck on sandy Sansing dealer ( Milton Florida (850)6236866 like 4 times, they replace few sensors and update software on first time, but day after I was there again, and again and again. Now, they have my car o shop for over 40 days but they can find or replicate de issue, of course to replicate the issue you need to drive the car, and according with then they drove the car for 50 miles with no issues( and of course nobody wants to drive a car that can stops in any minute ). I ask the Dealer if a fuel pump could cause that, they had no clue, but they gave me a price for replace both, so at this point I'm extremely frustrate, cause I've a car with a brand new engine that always was serviced on Jeep Dealer, that I can't use and who has all technical capability is incompetent to fix. I saw lots of cases like mine on internet. I could get someone or my self kill. Any help is deeply appreciate

Jeep Grand Cherokee Engine Failure and Lack of Accountability by the Manufacturer I am writing to bring to your attention a distressing situation regarding the Jeep Grand Cherokee and its e$th ongine issues. I have been experiencing an ongoing nightmare with my vehicle, which was supposed to be covered by a 100,000-mile engine warranty. However, after only 8,000 miles, the engine suffered a catastrophic failure, and Jeep has chosen not to take responsibility for the problem. It is evident that this engine has a significant factory defect, as my research has revealed numerous cases of the same issue. Many owners have faced similar engine failures, and it is disheartening to see that Jeep has not acknowledged this widespread problem. Compounding the issue is the lack of available spare parts for the necessary repairs. As a result, my vehicle has become inoperable, leaving me with a substantial financial burden and an unusable car. I am writing to the federal safety agency with the hope that you can investigate this matter further. The safety and well-being of consumers are at stake, and it is crucial to address this issue promptly and thoroughly to prevent further incidents and ensure accountability from the manufacturer. I kindly request that the federal safety agency launches an inquiry into the Jeep Grand Cherokee's engine problems, assesses the extent of the defects, and holds Jeep accountable for their failure to address these issues appropriately. Your support in rectifying this matter would be greatly appreciated by the affected owners and the wider community. Please do not hesitate to contact me should you require any additional information regarding my case. I look forward to your prompt response and assistance in resolving this troubling situation. Thank you for your attention to this matter. Sincerely, Luis Garcia

My cam failed after lifter got stuck at 65k miles, dealership repairs went bad after the first repair attempt they covered. I drove the jeep 19 miles after I bought it.. Then the low oil pressure light came on as the engine locked up. Was at dealer 6 weeks but it was not repaired correctly before i picked it up. On the way home from dealer oil pressure light came on half a sec before the engine seized up. I had to walk 5 miles and get a row truck from my work. 14 days to repair it after I purchased a new mopar long block. Dealer installed in 2 days. Cam lobs where gone and oil was almost magnetic due to camshaft lifter contact. I live in Michigan and i was half tempted to drive to fca in auburn hills just to show them 4 identical camshaft lifter failures I have seen in 3 years from friends and customers. I will probably have to file a lawsuit to recoup some if not all of the last repair cost. Old engine was dealership served at 3 to 4k miles religiously and it still failed. My jeep is ok now after paying for new engine before i even drove it home once. 2 months and $38k plus a few thousand in repairs all due to a shady dealership named Feldman automotive group.I don't think this is morally correct on any level. Makes me sick to pay 40k for the 2014 jeep grand cherokee srt used with low miles and tons more in repairs the first 29 miles. 2 months of hell. plus it ruined my financial stability. Why doesn't the dealership warranty a repair they did before a sale if it fails the same day. Something need to rectify my financial loss before I snap thinking about it 24-7. Feldman automotive group should of covered second repair attempt as first was unsuccessful.

*the federal safety agency Please Help* I purchased my 2014 Jeep Grand Cherokee brand new in June 2014 from a FCA authorized dealership. I have meticulously maintained, gently driven, and greatly cared for this Jeep since day one. Have only ever had the Jeep serviced at the FCA authorized dealership where I purchased. I have followed and complied with all Jeep manufacturer service recommendations since day one. At 115,000 miles, I am currently experiencing a loud ticking noise resulting from failed rocker arms and failed lifters. These failed rocker arms and lifters will result in complete and catastrophic engine failure. I am also experiencing significant engine oil leaking coming from a failed oil cooler. The Mopar oil cooler in this 3.6 Pentastar engine is made of plastic, and is highly susceptible to failure. I have talked to multiple ASE Certified Mechanics that both issues I am currently experiencing are extremely common amongst these 3.6 Liter Pentastar V6 24 Valve VVT engines. I feel very unsafe as the owner and operator of this Jeep Grand Cherokee, and have lost all confidence as it relates to the safety and reliability of this vehicle. If the vehicle cannot provide reliable and safe transportation, that completely eliminates all safety as a driver and for all passengers of this vehicle. *the federal safety agency* Please help the owners of the vehicles with these engines with appropriate recalls and procedures to ensure the safety of our vehicles. Thank you.

Their is oil being introduced into the coolant reservoirs. Jeep Grand Cherokee Ecodiesel. The vehicle are having failed oil coolers that stemmed from the failed EGR coolers. The driving of these vehicles for over a year awaiting a fix has caused the engines to have other failures. There has been over 10 recalls on these Ecodiesels since I bought the jeep brand new in 2014. They made a deal with the EPA lawsuit and did a software patch which changed the engine function issues, they did a patch on the power train control module, transmission control module, and apparently the ECM engine control module. I’ve had nothing but “check engine” light codes in since the first patch in 2016 that they didn’t put in the records, I have the work order showing the patch. In 2019 the lawsuit the EPA approved for them, allowed them to place a new patch that caused other components to continue to malfunction like the” high pressure fuel pump now. The dealerships are saying the failures aren’t due to their negligence and are causing consumers to deal with costly repairs that’s not their faults. I got a bill for $29,000 for a new engine, they said my jeep was under extended warranty but don’t want to help foot the repairs. Also stated they would reimburse recall work that customers paid for prior to recalls coming out within 60 days, but it has taken me over 4 years to try and get reimbursed. My car is at the dealership now and has been down since April 29, 2022.
