2015 Ford F-150: won't start

Filed Sep 25, 2026 · Electrical, Transmission · AZ

While driving my 2015 F-150 in live traffic, the vehicle suffered an abrupt, catastrophic powertrain and electronic control module failure, resulting in an immediate engine stall and severe traffic hazard. Multiple cluster warnings (Check Engine, Cross Traffic, Hill Assist) illuminated, followed by a total mechanical shutdown into a permanent "No Start" condition. The truck was towed to a Ford dealership.The diagnosis by the certified Ford technician (Repair Order #5804) confirms the root cause mirrors the exact hardware defect covered under Ford Recall 26S / the federal safety agency Campaign 26V237000. The transmission internal molded lead frame and Transmission Range (TR) Sensor suffered a severe electrical short circuit due to thermal degradation in the fluid.Crucially, this failure triggered a sudden, uncommanded downshift that forced the transmission into 2nd gear at driving speed. This created a violent rotational speed shock that physically shattered the internal planetary gears and clutches. This severe mechanical explosion left the "EXCESSIVE METAL" found in the oil pan, completely destroying the transmission internals.Simultaneously, the internal short circuit back-fed destructive voltage directly into the PCM reference circuit, immediately blowing the 10-amp main power supply circuit (Fuse F93). Because the shorted PCM completely killed module communication ("NO COMMUNICATION WITH PCM"), the computer was physically incapable of saving diagnostic trouble codes (DTCs) prior to replacement. The "TRANS TR SENSOR CODES" only surfaced once a new PCM was installed to restore communication. Ford is wrongfully denying my $8,581.23 recall reimbursement of my transmission and pcm solely because the defect itself completely destroyed the computer’s ability to log data before repairs began.

My 2015 Ford F-150 experienced a sudden, dangerous loss of throttle power while driving, forcing an emergency stop on the side of the road. The vehicle is now locked in a hard electronic no-start/no-crank condition. We diagnosed the vehicle and pulled active, stored trouble codes P0706 and P0707 for the Transmission Range Sensor (TRS).This failure matches the exact defect described in the federal safety agency Campaign 26V237 / Ford Recall 26S28. However, Ford Corporate and the local dealership (Washington Ford in PA) are actively refusing to provide an emergency diagnostic scan, towing, or physical parts replacement, claiming they will not honor the remedy until June 30th. This has left a hazardous, disabled vehicle stranded on my property. They have acknowledged this meets the criteria of the safety recall but want me to pay for the towing of the disabled vehicle, diagnostics, and repair upfront including the lead frame which the recall notice specifically states should be replaced because the codes were thrown before reprogramming.

The transmission downshifted at about 65-70 mph and after it stopped it wouldn't start or move. towed to Beach Ford and was quote $1700+ to fix.. Was told pan was pulled and they said "large chunks of metal were found". {Not surprising after downshifting at 65+mph...} Than I was quoted $7500+ for an Jasper aftermarket rebuild transition and i would suppose it still has the potential for lockup, especially if ford cant fix the problem until mid July!!! I think lives are at risk, the downshift is a very violent experience and total loss of control is very possible especially in wet or snowy conditions... I'm open to suggestions for additional contact information IE: Sen or congressmen ...Thank You

Vehicle unexpectedly down shifting while driving causing vechile to jerk. After parking truck, truck presents a no start condition and unlit gear selector lights. While driving truck will go in and out of limp mode. I have scheduled a appointment to bring the truck in for a diagnostic test 03/31/2026.

I was driving my 2015 Ford F150 and just pulled into the parking lot. The lights on the dash started going off (airbags, parking detectors, big wrench, etc), however the vehicle driving wasn't affected at that time. I immediately stopped and parked, When I returned to my vehicle it had full power, but wouldn't even attempt to start. I had no choice but to tow it to a nearby Ford dealership in Grapevine, TX. It was ultimately diagnosed with a bad "Transmission Lead Harness." The dealership told me that this was a recall item on many F150s, but for some reason, not on mine. I researched this specific issue and found that 2011-2016 models of F150 were affected. It shows an investigation was opened for 2015 models as well. My question is why my specific vehicle is not under a recall. This could be a potentially dangerous issue, i'd think. So, right now I'm looking at a nearly $2000 bill to repair my vehicle when they get the parts in on Friday, 10/10/2025. I believe that if this is a recall on other with the same transmission lead harness, why is mine separated from that. I was given no warning other than the lights going off just before shutting of my truck, then it wouldn't start again. Thankfully I was in a populated area and not in the middle of nowhere. Please advise on any possible what I can get reimbursed for this issue.

While driving at approximately 35 mph, the blind spot warning and rear traffic warning system indicated that there was a failure to the system. I parked the truck and then tried to restart the vehicle. The truck would not start. When it was diagnosed at the dealer, they found a faulty lead frame in the transmission. This part was then replaced. I have checked with Ford and my vehicle is NOT being recalled at this time. I have seen other recalls involving lead frame in other fords that have the same transmission as mine.

the truck has been acting up for several months now. it has been throwing out strange codes when attempting to start {parking brake malfunction, oil light, power train system default, ect} and often times it WILL NOT CRANK unless we hook it up to a battery charger for just a bit of time. The truck has a new battery that was installed by autozone, where it was bought {6 months ago}. Since we were in town, we stopped by autozone to get them to attach the code reader. {power train system and ABS malfunction} while driving, later in the day, the trucks auto start/stop system turns itself on and stops the truck dead in its spot.(danger: we were pulling onto the road {fm 2100} during rush hour traffic, when the trucks system went haywire and stopped us dead in our tracks in the center of both turn lanes and two of the main lanes.) there was no restarting, nor were we able to get the gear to change into neutral in order for us to be able to move it out of the main roadway. when we were finally able to move it, we hooked a fully charged jump box {one rated for up to semi truck sized vehicles} to it to get it started, and it simply would not crank for quite a while. at this time, we took the opportunity to recheck the oil level, which was set at full. After several minutes of begging "the truck" to just start so we could just take her home, it finally cranked up and home is where we took her. the truck has 19771 original miles on it. it was drove off of the show room floor, back in 2015, with 6 miles on it, and has had absolute regular maintenance and has only had one owner.

Two weeks ago my 2015 Ford F150 died in a parking lot. I drove it in fine, walked into the store, and when I left the store the truck was dead. Battery was good, alternator was good, but would not start. I had it towed to my local Ford dealer. Three days later they informed me that the starter was bad and it was replaced. Two days later I'm driving at highway speed (approx 70 mph) and the truck violently downshifts from sixth to third gear causing the tires to lock up and the vehicle to skid approx 20 ft in NYC traffic. Luckily there was no one close behind me although there were numerous car horns beeped and swerving traffic as I rapidly decelerated. The truck remained in third gear until I moved into the safety lane and the RPMs (due to slowing) returned to normal. The instrument panel only displayed a message "Contact Dealer". I shut the truck off and the turned it back on with no faults indicated and limped it home. Since then the truck has repeatedly failed to start. It will start fine for a day or two, and then nothing when the key is turned. I had it towed to my local service station where the mechanic informed me that the computer code errors indicated that there were multiple errors with the transmission. The soonest that the Ford dealer can inspect is 35 days from now. I see that earlier model Ford F150's had a factory recall for similar transmission problems. My concern is that due to electrical malfunctions within the transmission control module, Ford F150's may rapidly decelerate when the transmission inadvertently downshifts multiple gears causing accidents and possible loss of life.

The engine fails to start consistently using pushbutton and remote start on the ignition fob. It is not available as needed. As an elderly man and partally disabled wife, the inconsistant nature inhibits reliable usage of the vehicle if an emergency occurs. The problem has been reproduced by Kirk Brothers FORD in Vicksburg, Mississippi but at this time (vehicle dropped of on 6/21/22) no success has occurred to determine the cause! Only the local service department has worked on the vehicle and only one technician has been assigned for over 10 working days. Problem first appeared as intermittent in May 2022, and progressively got to the point vehicle would not start normally.

My truck won't start sometimes and turns off in the middle of driving. It happens every few weeks. It shows a message saying the oil I low but when I check the oil, it is fine.
