While trying to accelerate from 50 up to the posted speed limit of 70 on interstate highway 10, the ecoboost engine in my truck stalled and started to misfire and shutter so severely causing my speed to decrease that i had to pull over to the side of the road to prevent from getting run over. *tr
Tl* the contact owns a 2012 ford f-150. while driving 60 mph, the vehicle stalled without warning. upon restarting the vehicle, the service engine indicator illuminated. the vehicle was taken to suburban ford of sterling heights (40333 van dyke ave, sterling heights, mi 48313) where it was diagnosed that moisture was present in the engine compartment. the vehicle was repaired, but the failure recurred. the manufacturer was notified and did not assist. the failure mileage was 68,000.
This is my second complaint i am not sure to list this under engine or steering either way i am experiencing the same shaking and shuddering that i was before. ford fixed the so called intercooler problem but now it is experiencing the same shaking. in the past 2 weeks this has occurred multiple times when i first start out driving in the morning the vehicle begins to shake and shudder while driving at sow speeds of less than 45 mph it even did this yesterday at 5 mph. if you research this complaint there are 1000s f complaints online especially on the ford f150 forum. also my gas mileage is absolutely horrible at 13 to 14 mpg and that's on 45 and 55 mph roads in the country. the shaking occurs violently making the vehicle hard to control creating a dangerous situation especially on the freeway where the vehicle will slow down to 35 mph. *tr
Vehicle since brand new has a stuttering/stalling issue at 55mph and the dew point is high. attempting to pass a vehicle accelerating from 55mph and the truck either stutters or stalls. this almost caused a head-on collision. i am scared to pull out in traffic or pass anyone due to the inherent issue. ford did replace a intercooler/cac following tsb 12-10-19. this has not fixed the problem. we. i returned the truck still broke. the service manager at the dealership told me he has the same truck and that it is an inherent engine problem ford has acknowledged but they could not do anything for me. i am worried everyday i might die driving my truck and even more upset that i pay monthly for something that is broke. *tr
Tl* the contact owns a 2012 ford f-150. the contact stated that while driving approximately 65 mph, there was a complete loss of the engine power. the driver decelerated with force and then maneuvered into the next lane. the vehicle was able to resume normally. the failure recurred numerous times. the contact also mentioned that engine power reduced slightly sporadically. the vehicle was taken to three different dealers who were unable to duplicate the problem. the manufacturer was not notified of the defect. the approximate failure mileage was 3,000. the vin was not available.
After purchasing this 2012 f150 w/ecoboost v-6, i wanted to see how good of gas mileage i could get out of it. i also wanted to break the vehicle in before any hard accelerations. when starting from a complete stop, i would gradually make it up to highway speeds. i treated the vehicle gingerly until i wanted to test the capabilities of this ecoboost engine i had heard so much about. it was a cold january evening and there was no unusual weather (no rain or snow). i had been cruising at constant highway speeds for approximately an hour. the road had narrowed from a 4 lane highway to a 2 lane. i was stuck behind a vehicle traveling just above 50 mph. i reached a passing zone and decided to test the performance of the engine/truck. i depressed the accelerator to the floor and the engine spit and sputtered. i decided to ease off immediately for our safety. no lights on the dash illuminated as result of this engine problem. after this incident, i have noticed that at cruising speeds, there seems to be an engine miss around 60 mph while going up a slight grade. i have also noticed that when starting the vehicle, it (engine) does not start as quickly. the key has to be held longer. these problems are a direct result of the damage caused to the engine after the very first hard acceleration. *tr
Traveling down the road. got up to 55 to 60 mph lost power transmission stared jerking. power caught back up and lunged forward. at times the engine stalls and catches back up. at times when you put it in gear it feels like the power train is bumping as though your getting stuck are hit from behind. *tr
I had slowed down to exit off the freeway to get on another freeway. when i pushed the accelerator, the truck started to shutter, shake, and lose power. i took my foot completely off the accelerator and let the truck coast a short distance. when i tried to accelerate again, the truck seemed fine. it did this twice on the same day. i took it to the ford dealership and they told me the truck was fine. i have an eco-boost v-6 engine. *tr
While under acceleration in traffic, the vehicle lost power, explosion, fire, lost oil pressure, almost got into accident dealership diagnosed it as intercooler collected condensation that got sucked into engine intake causing the engine to explode a hole in the engine block. intercooler still had over a sip of water in it. *tr
I proceeded to pass another vehicle on i-75 just north of chattanooga, tn. the truck immediately lost power, check engine light came on, and i had to pull over to the emergency lane very quickly as the truck lost speed rapidly. i had to turn engine off and then back on to get power back. i took it to the ford dealer i bought it from and they told me they had to replace a part. it has been on back order ever since and the truck has repeated this problem approximately 5 more times. the service dept was kind of vague about the problem but they just kept telling me it would not hurt the engine. *tr
While attempting to merge into traffic pulling a trailer i pushed the gas pedal and the truck down shifted but would not accelerate. the truck will drop into 3rd gear and will not exceed 4000 rpm. this has occurred several times and has been in the shop 3 or 4 times. it has also happened without a trailer. on several occasions i have had to pull over and turn the truck off to get it to go. sometimes i can just come off the pedal and press it again to correct. this is a dangerous issue that could cause an accident. the dealer has reprogrammed the truck several times and replaced the converters twice. i have asked ford to buy back the truck but they have not responded yet. the truck is going back into the shop tomorrow and i am considering utilizing the lemon law. *tr
Pressed gas to pass a slower moving vehicle and it bogged and had a major loss of power. it was raining out and it felt as the truck sucked some water into the engine, research leads me to believe it was the cac, or intercooler. *tr
2012 ford f150 with ecoboost mileage 2,500 - driving for approx. 2hrs on highway - raining off/on throughout drive - when accelerating to pass a vehicle going uphill the f150 lost power and bogged down - stuttering along - had to quickly pull over to slow lane - to avoid possible accident with traffic that was approaching in fast lane. the truck continued to stutter along at various times after the 3 hr trip. no problems since but truck has not been used much (3,600 miles now). saw on other forums and this site that other f150's with ecoboost are having this issue. took truck to dealer - they had not heard of any problems with the ecoboost. i showed them the printout from this site highlighting the tsb 12-6-4, which they are going to do. my father purchased the same truck and he had the same thing happen to him this september. hope this works before someone gets hurt or killed. *tr
