On this new F-150 with eco boost engine, the engine now has shut down 2 times the last 2 days on June 12 and 13, 2013. The engine oil light came on. I was only going 20 mph when this happened both times since I was stopping at the stop sign 3 blocks from my house. On the highway with the engine in cruise control at speed of 60-65 mph the transmission goes from 6 th gear to 5th gear alot.

While traveling at highway speed on I-69 in Michigan between lansing and flint, I attempted to merge into the passing lane to allow merging traffic from the on-ramp onto the expressway. In order to change lanes, I used firm acceleration to avoid contact with the faster vehicles in the passing lane. The steering wheel started shaking violently while the check engine light flashed. All forward acceleration was impossible the engine sputtered for 45-60 seconds after the event until power was restored. One week after I took delivery of the truck, this problem began on a similar trip on the way to toledo around the dundee exit on I-23. The vehicle only had 400 miles on it at the time. This was in early May 2013. I took the vehicle to the dealer who performed the tsb replacing the charged air cooler and updating the software in the engine control module. This can be repeated on any trip of significant duration on a rainy day. The tsb did absolutely nothing to address this problem, and I fear for my safety as well as my family's safety. I do not let me wife drive the car because she would not be as well equipped to deal with an event like this. I feel cheated by Ford, and I am not satisfied with their attempts of fixing this. Furthermore, I know every time this happens the engine is taking in large amounts of water through the intake, and this is catastrophic for engine life and longevity. Please pursue recall efforts now on this horrible engine.

Vehicle lost power when trying to pass another vehicle. Note I was in a 75 mph area trying to pass a vehicle that had trash flying off truck. In any case when I punched the accelerator the vehicle did a nose dive as it lost power. It took about 2 seconds for the vehicle to restore to normal operation.

Traveling on the interstate during heavy rains. Traffic in my lane stopped. I tried to change lanes and accelerate briskly. When I tried to accelerate, the vehicle started to shutter and the engine power died. It seemed to go into limp mode. The check engine light flashed several times. The vehicle would not accelerate and left me hanging in the travel lane with faster traffic almost causing a crash. Vehicle is one week old and has approximately 600 miles on it. The engine is the Ford ecoboost 3.5L V6. The vehicle had to be turned off and restarted to get it to drive normal again.

While on I95 in Virginia, after traveling for about an hour with the cruise control on in an intermittent rain, I attempted to accelerate to pass another vehicle. I depressed the accelerator and the truck started to shake and buck. The check engine light started flashing and I was not able to accelerate. Any attempt to do so caused the truck to jerk and shake. As I moved to the right lane to get to the shoulder, the light stopped flashing and the truck behaved normally. I could not replicate the incident since I did not drive at a constant speed again for any period of time remaining in the trip. This occurred in a 2013 Ford F150 XLT supercrew with a 3.5L eco boost engine.

2013 F150 XLT w/ ecoboost 42K cost, had to accelerate to get out of the way of a potential accident and the engine stalled started missing barely missed totaling the truck had to plow in to a grass median to keep from being hit. I was able to restart the truck and get it home and have not driven it since. I am so disappointed. If this is not a safety issue I don't know would be, this is scary stuff.

After leaving I-20 and on the entrance ramp unto I-95 North, I was accelerating to merge into traffic when the transmission shifted into a lower gear, the engine RPM went up, but the vehicle didn't accelerate. I had to brake and pull of to the shoulder to allow traffic to pass. The check engine light came on and it felt like the transmission was shaking, after a mile everything was normal. We were experiencing heavy rains on I-20 West of charleston SC.

I went to pass a slow moving vehicle and only had a short distance to pass. I pressed down hard on the accelerator, the engine shutdown, truck was coasting, and the orange traction slip light came on. Then the engine came back on and I was able to finish passing. This was in carlsbad, nm. I took it to the local Ford dealer they said there nothing showed on their diagnostic computer, but they did try to charge me $150 labor. I refused to pay, because this is a new truck and the incident happened twice driving into carlsbad. I have tried to duplicate the incident once since, but the engine did not shutdown.

Not getting sticker mpg; took vehicle back and Ford milham dealership in easton pa off rt 33 said " there is nothing we can do about it" power steering rack also malfunctioned at 7,000 miles. Dealership manager agreed there is an issue with the vehicle. I dropped the vehicle off on a Wednesday. Thursday night they called and stated everything checked out and "Ford says it's within range". I was also told I will receive a survey online - I never received the email to communicate my dissatisfaction with the vehicle and the dealership. Vehicle now has 10,000 miles and now I get 16 mpg on highway (no city driving).
