My 2015 Ford F-150 truck has had multiple issues related to performance issues, with only 80,000 miles on it. I have had issues with it losing power while driving, both with and without towing a trailer where it just powers down on the highway from 70-75 mph down to 40-50 mph in traffic. I usually just have to pull over, turn the engine off and then turn it back on and everything runs normal. It is currently at Phil Long Ford in Colorado Springs, CO, having the short block and driver side cylinder head replaced at 80,000 miles because it was smoking out the exhaust and they determined that it had coolant leaking into the #4 and #5 cylinders. This is after it had a completely new engine installed at 75,000 miles due to coolant leaking into the 3# cylinder and causing severe damage to the engine. It was in the repair shop from August 2023 until late December 2023 because the engines were are backorder. The Passenger side cylinder heads are currently on a 13 month backorder according to the dealership, which is why they are only replacing the short block and Driver side cylinder head this time, after only 5,000 miles on the replacement engine. I have also received multiple recall notifications regarding this vehicle, the most recent of which was on 4/22/2024 for #24E03 POWERTRAIN CONTROL MODULE SOFTWARE UPDATE, none of which have been repaired during the multiple times and extended durations that my vehicle was at the Ford dealership for repairs. Two recalls existed and should have been repaired when my vehicle was at the dealership between August and December of 2023, and the most recent recall shows "No Remedy Available" for a PCM Module Software Update?

When I was driving a light came on that said low oil pressure. I checked the oil, and it was full. Driving to get it checked out the engine stopped. I had it towed to the FORD dealership. The engine failed at 81,000 on my 2015 FORD F-150. I was charged $220 for the FORD technicians to say "they do not know why the engine failed but for $16,000 they will put a new engine in." I asked for details as there is low miles on the engine. The technician said "they would be happy to tear apart the engine, for a fee, to find out." I asked about a warranty they said the motor is good for 60,000 miles after which point it is not covered. I found, on the internet, that the 2015 2.7 EcoBoost engine has problems with oil leaks and that the piston melt, fuse together and the engine stops. I also found there is a federal investigation into the 2.7 EcoBoost engine. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My latest issue is with the 2.7 ecoboost engine. I had a total failure of this engine last year and am still awaiting a replacement that I am paying for. This is unacceptable as I had this vehicle serviced according to maintenance schedule. I also have had systems report failure such as the hillside assist and the electronic parking brake. Additionally, the automatic transmission has locked up in third gear quite a few times. There are other issues such as a leaky oil pan and such.

This engine defect is well known to Ford ; it involves the 2015-2017 2.7 liter ecobost. These engines were produced with a faulty oil pan gasket. I just paid to replace the third oil pan. Taken in totality these leaking oil pans are a safety issue since oil is deposited on our roads leading to slick conditions and deteriorating road surfaces. Ford's most recent TSB related to this defect is TSB 24-2098, which superceds TSB23-2330. This defect effects thousands of Ford's 2.7 liter ecoboost engines.Please examine this safety issue. Thank you

The exhaust manifolds have warped, breaking a nut and stud and causing an exhaust leak. I am finding this is an extremely common failure indicative of a design flaw. Ford will not cover this under any extended coverage, nor offer financial assistance to repair this failure.

The oil gaskets on the valve covers and oil pan are defective and leak. This causes oil to be leaked on the engine and can catch fire. Ford has stopped making the defective parts and now charging customers for the repair. If the repairs are not made, the engine fire is a probability.

Both the drivers side and passenger side exhaust manifolds have sheered the support bolts off potentially causing parts to come loose and fall off while driving. This is a known and well documented issue on the trucks with repair estimates being 3-$4,000.

During driving the engine will shut down and the truck stops. Multiple engine lights will display on the dash expressing multiple systems fails. The wrench icon will display. The safety of others and myself were put at risk due to the truck shutting off during forward movement and putting everyone at risk of a rear end crash. Yes, the issue has be reproduced and confirmed through self driving and investigation into the issues via online UTube and Ford forums. The truck has been brought to a Ford dealership for inspection. The Ford dealership has stated the the aux trans pump has failed leading to a shut down in the system and presser build up in the engine leading to failure to valve covers and oil pan expansion. Currently Ford has a service bulletin for the oil pan and the related parts that must be replaced to fix the issues, however this is still at the cost to the public when Ford is aware of the issues that cause shut down to the engine. This is on a 2015 ford F-150 XLT, 4x4, 2.7 eco boost engine.

The plastic oil pan is leaking and have to replace the oil pan every time there is a leak. This is the 4th time this oil pan has leaked and now I cannot order an oil pan as it is out of stock. This is an issue for the past few years and needs to be fixed as I do not have $1000+ to fix it every time this happens.

My 2015 F-150 3.5L ecoboost experienced a sudden loss of power during highway speeds and shut off. I was in rush hour traffic and almost caused a few accidents as my truck seemed like it went into "limp mode". While my steering wheel was tight I managed to get off the road safely with no power whatsoever. My idiot lights were flashing like crazy and stated "Advance Trac Service" and "Hill Start assist not available". I let the truck sit for a bit and restarted it. It ran solid another 15 miles. Today I'm getting Advance Trac message: "Advance Trac Service" and "Hill Start assist not available", all while the engine check light remains on. I have read multiple issues similar to mine but there does not seem to be a recall for this. This is a VERY unsafe ordeal and very scary. Had my daughter been driving, this may have been an accident for sure. I see Ford "extended" the warranty to cover any issues. But I do not drive my truck that often and I find it hard to believe nothing is being done about the "throttle body" issue (from my reading). This is even happening to Ford trucks overseas. I get they do not have any say in the US, bu it does show this is a MAJOR issue.

PS111 Error Cody: Throttle Body Assembly is malfunctioning. My vehicle lost power steering and went into full shut down mode a dozen times over the course of driving it the latest ~500 miles with the truck shaking at a stop before restarting it and working again. Many times this could have been FATAL collisions as they happened on roads without shoulder lanes. This issue is SUPER scary to have your vehicle randomly shut off on you leaving you minimal time/distance to react and often in the middle of the road with multiple lanes. I've had it at the Ford dealership for 3.5 weeks where they are trying to fix it for $1,100, however, they said Ford currently has 15,000 of the same part on back-order. This issue should be a safety recall immediately, in addition to the shear number of the same part on back-order is clearly an indicator that Ford has an engineering issue and should be held liable to replace the part that frequently defaults at their expense but also to keep the roads safer.
