2015 Ford F-150: grinding or squealing brakes

Filed Sep 12, 2026 · TX

I took my sick disabled mother's truck to the same dealership that she bought the truck from in 2018 with a full cash payment. The truck is a 2015 Ford F-150 platinum edition and it only had 40 thousand miles on it at the time and the person i believe that was over the service department was the first person i talked to at this dealership and i told her that my mother was sick and disabled and on oxygen and we use this truck for her medical transportation to her doctor's appointments and that the truck is our only means of transportation and that i am a burned out full time caregiver in need of urgent help to get the truck fixed and any recalls fixed so the truck would be safe to drive again and she told me its okay and that she has been there before and it made me feel so good to finally have someone that understands how it feels so she immediately had a brand new 2026 Ford F-150 XLT texas edition loaner truck already waiting for me after she said that she could get me in but without a loaner vehicle and she immediately called me back and said she got a loaner for me but i thought it was odd that she managed to get one that fast well to find out the loaner truck was pulled right from their fleet inventory and still had the factory monroe sticker still on the windshield and after awhile i noticed the dealer plates where expired and she arranged the entire process to bring the truck in on August 1st at 8:45am on a Saturday morning to have all of the recalls fixed and any damage or mechanical issues that may have been caused by the recalls and we brought them a very well maintained fully running truck except the engine light was showing because of a violent downshifting after the dealership called and said the truck was completely fixed and running great downshifting fixed. Driving home same day the truck started pouring smoke, sparks, grinding, and slapping barely made it in driveway catastrophic totaled truck sitting at dealership lot since August 12th!!

The vehicle was previously taken to an authorized Ford dealership to complete Safety Recall 26S28 (the federal safety agency Campaign 26V237000) for unintended transmission downshifts. The dealer applied the mandated software patch. However, this safety remedy has completely failed. While driving at highway speeds, the vehicle experienced severe mechanical gear grinding and twice suffered sudden, unprompted downshifts into a lower gear. This caused an immediate and dangerous spike in engine RPMs and a sudden deceleration, creating a high-risk highway crash hazard and a potential loss of vehicle control. The physical hardware defect (the molded transmission lead frame) is actively failing and bypassing the software safeguard. The authorized dealer, Nielsen Ford of Morristown, is currently refusing to replace the defective hardware under the safety mandate without a permanent dashboard code, despite the vehicle displaying clear, dangerous physical symptoms of a failed recall remedy.

The transmission will sporadically shift hard and make a squeal noise on acceleration and deceleration between 20 and 50 MPH. Yes it's available for inspection. It has never stopped completely so the risk factor is unknown. Not reported to dealer or independent mechanic at this time nor has it been inspected by the manufacturer or government agency. There are no warning lights dash messages ever displayed.

When driving the transmission tends to constantly down shift and feels like a vibration/and grinding when doing so. Also the rear wheels sometimes lock up briefly when when accelerating. (the symptoms are very similar to the 2014 f150 transmission issues). This has been going on for appx 1 yr and tends to happen more frequently.

The transmission is having deceleration at high rates of speed on the highway. It is have severe hard metal clicks that cause the front end to lock up and squeal tires at over 50 miles an hour. It is failing to take gear especially in drive. It is resulting in rolling backwards (I live in the mountains and at times haul a trailer resulting in high safety issues.) Unable to take gears and take off from a stop at times. This is all putting me at high risk of having a wreck and losing control especially on narrow mountain roads and traveling busy highways. I live off a corner and people come around fast and the transmission is failing. The issues with the 2014 is the same issue I am having with the 2015. I am struggling to get the dealership to manage the issue. It varies in frequency, but is profoundly limiting my ability to do my second job and travel due to fear of getting in an accident injuring myself, my livestock, or others. The truck at times will flash a wrench symbol, but other times will not. They started earlier this year. I have had the truck at the dealership 2x and get poor service since it is not a 2014, but experiencing same issues as that model.

LUG NUTS are distorted. They won't allow the lug wrench that comes with the vehicle to remove or tighten them. I was unable to remove a wheel after tire went flat due to 2 of the nuts warping and not able to find ANY wrench that would work. I had to grind those 2 lug nut "caps" down with an angle grinder (scuffing the alloy wheel) and then chisel the caps sides down far enough to get a 20mm socket on the nut beneath the "cap". I cannot use this F-150 until I find replacement one piece lug nuts to fit. I will not put the crappy capped nuts back on this vehicle. Ford may have saved nickles, but going cheap on something so vital will cost them many future customers, including me.

While driving the vehicle a grinding noise emanated from somewhere near the front wheels. The was also the feeling of a shutter or a shake from the same area. This was felt in the steering wheel. After taking it to the ford dealer, we were told they took a fluid sample from the transfer case and found it contaminated with metal. At 44,576 miles, we had to replace the transfer case.

The exhaust manifolds have warped causing studs to break leading to an exhaust leak. This is a very common problem with these engines. It produces a squealing noise under acceleration
