Wipers failed to operate normally while driving. Wiper started moving very slow then stopped moving even with wet windshield. Upon research the problem was a seized passenger side pivot in the wiper linkage that required replacement of the Wiper Linkage assembly. No warning or noticeable problems until this occurred and vehicle was difficult to operate in rainy conditions.

The vehicle’s original engine began producing excessive white smoke during startup. The vehicle was diagnosed by AutoNation Ford, and it was determined that the passenger-side cylinder head was cracked near the exhaust port. This defect allowed coolant to intrude into the passenger-side turbocharger. Due to the extent of the damage, the engine required full replacement. The engine was replaced with a used motor under a third-party warranty on August 21, 2024. The replacement engine is now experiencing the exact same failure symptoms. Specifically, the vehicle produces white smoke at startup consistent with coolant intrusion. Bozard Ford performed a diagnostic evaluation, completed on February 27, 2026. Their findings determined that the replacement engine has the identical defect: a cracked passenger-side cylinder head near the exhaust port allowing coolant intrusion into the turbocharger. This repeated failure raises significant safety concerns. Coolant intrusion into the turbocharger and combustion chamber may lead to engine misfire, loss of power, potential engine damage while driving, and possible sudden engine failure. Additionally, burning coolant may damage emissions components and create hazardous driving conditions due to reduced visibility from exhaust smoke. The fact that two separate engines in the same vehicle have experienced the exact same cylinder head failure suggests a potential design or manufacturing defect specific to the 2.7L EcoBoost engine. I respectfully request that the federal safety agency investigate this issue to determine whether this is a broader safety-related defect affecting other 2015 Ford F-150 vehicles equipped with the 2.7L EcoBoost engine. Please let me know if additional documentation, repair records, or diagnostic reports are required.

[XXX]: check engine light was on and codes P2196 and P2198 were present. The dealer suspected it was the purge valve, causing the problem so they replaced it and reset the codes. 10/10/24: I brought the truck in to have it looked at due to the check engine light being on again. I was told the lead frame needed to be replaced but was on backorder. The bill to diagnose this was 196.80 and I was told I could still drive it. On [XXX], I had to bring my truck in to be inspected because while I was going about 70 mph it all of a sudden downshifted and jerked me forward like it was going to abruptly stop. The check engine light came on and I had to drive pretty slow to avoid a breakdown on the interstate. Very scary to have this happen in interstate traffic It could have easily caused an accident. At this time, It was brought to my attention that the downshifting could also be related to technical bulletin 1495. Since we couldn’t get a real definitive answer on what was going on and the lead frame was on backorder, I decided to try and have the case connector in the bulletin removed and replaced as well as do a transmission tuneup on 10/23/24. This bill cost me $383.77. All codes were cleared and all appeared to be working correctly. On [XXX], I was driving on the interstate at about 70 mph and my truck seized up again and jerked forward, again scaring me and potentially causing an accident. I drove it very slowly directly to a repair shop. It was there until November 7, 2024 after the lead frame was replaced. That bill cost me $1321.68. I decided to file this complaint after I had seen a news article that this downshifting was being investigated for the same year as my 2015 Ford F150 for a safety issue.

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)
