Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: We aren't rating the 2015 F-150 as "bad" yet, but there is an early trend of complaints about the transmission shifting roughly.

problem #15

  • 6,900 miles


Driving the Ford F150 (V6 ecoboost) on a city street (35 mph) it has failed at random times (I've now seen this issue more than 3 times) usually with 3 major failures. These 3 failures (1) engine, transmission, and emissions 2) brakes & suspension 3) restratins & driver assistance) cause the truck to transition to 'limp' mode which can actually be just as hazardous. If I'm turning onto a road with a 55+ mph speed limit I need to accelerate but if this system fails, along with the restraints & driver assistance, this could be a very dangerous and life threatening situation. The reason why is that the restraints & driver assistance goes off now disabling my airbags, etc. And if I now get hit (because now I'm in limp mode going about 7 mph) I have lost a great deal of 'built-in' protection without the airbags. Translate that to driving on a highway and encountering this situation and you can see that loss of life is not out of the question. I've taken the truck back to Ford for the warranty work and they say they believe it's an electronic throttle body controller that has gone bad and needs to be replaced but right now it's at least 3 weeks before they can get a replacement part. Compounding this issue is that Ford had issued an internal recall for V8's built at the same plant as my V6 ecoboost truck for the same type of issue.

The issues started around mid July 2016 with about 11-12K miles. I was turning onto a side road where doing maybe 10 mph and the engine stalled, it restarted while in motion and I continued. The hill start assist and advance trac warning lights came on. Later that week it happened repeatedly. The dealership here in town (not where I bought it) looked at it for a few days, they thought it was because of, "all the after market stuff (radio etc) I had (professionally) installed". they believed it was the power converter so they replaced the converter when it came in (the 110V converter) I got my stereo stuff reconnected and kept driving it. Then the engine would not stall, but the warning lights would flash advance trac and hill assist. After a few days, it began to stall again, almost getting me hit pulling onto a road with 50mph traffic. The truck died, and wouldn't "restart" itself. So here I am parked on a two multilane 50mph roadway trying to start my truck without getting killed. It also happened again while pulling off this same road into a side street with a big ass rv coming at me, I was able to coast into the side street and then restart the truck. I brought the truck back in and they said that it might be the throttle body. So, I got my truck back today with the throttle body replaced. I go to drive away and my head unit/ display will not illuminate properly. I thought it was dimmed, but it wasn't. so I drive in a circle to bring it back and it illuminates like it should. So I leave and I drive back down the main 50 mph road and while accelerating away from a stop light there, the advance trac and hill assist lights flash on again. I take it right back and it is now there getting looked at again.

The contact owns a 2015 Ford F-150. While driving at different speeds and attempting to make a turn, the advance trac control light illuminated, which caused the vehicle to slow down. The failure was not diagnosed. The manufacturer was not made aware of the failure. The failure mileage was 7,300.

Throttle body failure - 2015, F150 in motion, stopping for red light. Following red light truck had minimal power, just enough to limp to side of road. Thankfully not in atlanta, ga traffic but dayton, tn traffic. Turned vehicle off and restarted engine and drove 2 blocks to Ford dealership "service department" where I purchased the new F150 XL 6 months earlier (12,000 miles). Told service manager wrench light appeared along with advance trac warning light. Service technicians unable to duplicate problem on computer or test drives. Even though they had seen the same problem before "Ford Motor Company " would not allow them to repair it unless they were able to duplicate the problem. I contacted regional service manager for East Tennessee, I stated to her this was not a local dealership problem, financial problem or was it a warranty problem (12K of 36K). This was a safety problem. Again she stated if they couldn't duplicate it by driving or computer diagnostic test they couldn't fix it. I also spoke to her superior he apologized but they cannot fix a problem they cannot duplicate. After threatening a to contact my lawyer, which did not phase her. I picked up my truck and was heading to another local dealership to trade it in, because Ford said their was not a problem with it. When it "duplicated" the same problem within 15 minutes of leaving the dealership. It is now back at the dealership, after a technician was sent to hook up a computer while vehicle was running along side the road. Had to use road side assistance to get back. Will never purchase another Ford. My belief after reading other post on this site Ford does not care about customer satisfaction or safety.

The contact owns a 2015 Ford F-150. The contact stated that while driving at 70 mph, the vehicle abruptly decelerated. The wrench and limp mode warning lights illuminated while the failure occurred. The contact was able to coast on to the road shoulder and restarted the engine however; the vehicle did not regain acceleration. The vehicle was towed to the dealer whom performed a diagnostic that located a failure code at the throttle body. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 76,000.

The throttle body failed while traveling on I-94 in a single lane construction zone during a severe rainstorm. The throttle body is a part that controls the air intake on the engine and when it fails the engine loses power and cannot pull a trailer. The engine does not stall, but it does shudder enough to shake the vehicle. I turned the vehicle off and upon restart could move out of traffic. This occurred two more times till I could make it to a dealership. This is a known problem and the part is backordered due to demand. When this part fails it could put the driver and other vehicles in a life situation as I was without an area to pull off and semis on the road with poor visibility. I have been waiting at a dealership for 3 days for the part stuck in my trailer and no known timeframe for when the part will arrive. Learned this morning that the part was shipping was Canada, but no delivery timeframe.

10,600 miles on this new 2015 Ford F-150 ecoboost 3.7 engine. While driving home from work at 5:15pm on highway 84, the truck lost all power and coasted to a stop in heavy traffic. The truck shook and vibrated, the engine light, anti slip and tool icon light all came on. The truck showed the engine was at 1000 RPM but would not move or react to my pushing the gas petal. I was able to turn off and the truck and restart to get moving again before it repeated the same events 5 more times. I was able to get on a service road and limp I the truck home. The truck dying with highway speeds is deadly. $45,000 2015 Ford F-150 supercrew 4X4 10,600 miles

Windshield cowl panels leak rain water into top of the engine where the two cowl pieces meet in the middle. I suspect looking at other 2015 and 2016 F150 models they have or will have the issue of leaking water onto the engine. Besides possible corrosion or damage to engine, this could cause the engine to stall and maybe a safety problem.

New 2015 F150, accelerates and decelerates on its own. Brakes create loud noise. Wiring harness as it relates to the shifting of the truck was replaced within the first six months as well. Auto off frequently refuses to restart. Loss of complete power on highway.

Truck shudders as transmission torque converter clutch attempts to lock up in third and fifth gear at light throttle position when shifting upward. This vehicle has the 2.7L engine with the auto stop/start feature. With this feature disabled the engine attempts to stall after stopping as if the feature is trying to override the off switch. After coming to a rolling stop and then trying to accelerate into traffic the engine will bog down and then a split second later feel as if it is going to full throttle without me depressing the throttle further. The engine speed surges when attempting to lightly accelerate and maintain speed with the flow of traffic. -Ford needs to give owners the option to turn off the auto stop/start permanently. I was not informed this feature could not be removed when I purchased this vehicle. The dealer attempted to shut it off and only succeeded in disabling the remote start feature. I will never buy another vehicle with the auto stop/start annoyance.

New 2015 F150 with a vibration/ shudder coming from what feels like the transfer case or possibly the drive shaft. Happens when trying to shift from gear to gear, and on inclines...feels like it is going to stall. Also happens when just cruising at certain speeds. I've had it to the dealer twice and they say everything is fine but they have felt the same problem with this vehicle and ones on their lot. Vibration could lead to more serious problem and actually stall the vehicle while in traffic.

This vehicle has the 'stop/start feature;' which actually shuts off the engine when at a stop and is supposed to 'restart' when the gas pedal is depressed; the 'electrical systems' are supposed to be operative; how power brakes are 'electrically operated' is beyond my comprehension; however, a few days after purchase I was at a stop lite when the engine shut off, and eventually re-started' by itself; the dealer sales staff never informed me of this 'feature, ' and also did not tell me there was an 'override switch on the dash; the fact that I did not override it, and that the engine did not restart when the gas pedal was depressed, to me means that this 'feature' is, on this vehicle, inoperative, and therefore inherently dangerous and life threatening; my wife refuses to drive it, and it was towed in to the dealer on 12/21/15, where it remains; I refuse to drive it as well; lastly, the vehicle exhibited no 'stop/start feature' upon a pre-purchase test drive with the salesman in which we made numerous 'stops' and a friend of mine was with me on that test drive, who will attest to this fact; likewise, it did not have any 'problems' until almost three weeks later, during which time I drove the vehicle daily.

Total loss of power while driving. At 3022 miles the engine cut off while at 40-50mph. A smart data link was replaced. At 3619 miles the engine cut off again while accelerating at 40-50 mph. Both incidents happened within 5 minutes of starting the engine. Several alerts pop up on the screen to include loss of braking, hill assist, and service engine. First repair was for 10 days. Current repair is 3 days and counting. Currently I am aware of another F150 with the ecoboost 2.7 engine having the same problems with several attempts to fix.

After morning startup, vehicle stumbled, hesitated on acceleration into traffic. Vehicle stalled after approximately driving 1 mile. Would re-start, only idle, then stall when put into drive and attempted to re-enter traffic. I had towed to closest Ford dealership for warranty repairs. My vehicle was returned over two weeks later. The service invoice outlined that the low pressure fuel pump was found bad, shorted and connecting plug to harness melted. They replaced fuel pump and repaired harness plug. Vehicle was not fixed. Over the two week period the vehicle was at the dealership, the fuel pump driver, body control module, and last the engine control module was replaced to repair the problem. My major concern is the melted fuel pump plug. I would think there would be adequate fusible link protection to keep this kind of problem from happening especially when affecting an in tank fuel pump. This might lead to fuel fires and also accidents due to loss of power from the engine. I was fortunate to be able to safely get my vehicle on the road shoulder, and then onto a side street with minimal traffic. Another issue is that one device failure creating failures in multiple vehicle control systems that would cost the consumer thousands of dollars out of warranty to repair. I was told that a Ford field engineer was sent to assist the dealership, after his visit, the ECM was replaced which made the vehicle functional again. Adequate overcurrent protection on the fuel pump should have prevented damaging the other critical parts. Ford has put a lot of these vehicles on the road with the fuel efficiency new engineering as a major marketing tool. I fear the vehicle may have been rushed to production with inherent flaws that could be a danger to owners and the public.
