This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Ford ecoboost. Vehicle has few issues. First there is unexpected hesitation when pulling out in traffic. You are without power and subject to being run over. There are times when at highway speeds the engine goes limp when accelerating leaving you in traffic subject to being run over. Ford has replaced the cac and this has not happened since. When at speed and you accelerate a small amount, the engine will misfire and run rough. The lack of throttle response leaves you vulnerable when passing. Been at the dealer 5 times for these problems.
Vehicle acts as if it wants to stall during rainy conditions upon high acceleration, only during wet conditions does the ecoboost not accelerate when needed. Has caused 3 serious situations where power was needed and expected but truck sputtered and would not accelerate. This has been dangerous and dealer has no fix. I am unhappy with this engine. There are no lights that come on to warn you of the condition, and you cannot tell there is a problem when cruising at highway speeds, only when you go to pass or need power.
The contact owns a 2011 Ford F-150. The contact stated that while at a stop and attempting to accelerate, the vehicle stalled without warning. The vehicle was not taken to a dealer for a diagnosis. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure and current mileage was 13,000.
An example of what happens is this: Traveling along at 45mph, and pull out to overtake a slower vehicle, you accelerate aggressively. Upon doing this, the truck seems to stumble like it's hunting for the appropriate gear (@ about 45- 50mph). Also, it feels like an engine mis-fire. It's a disconcerting feeling that the truck does not accelerate as it should when you need it the most.
At about 30 mph while accelerating the engine will cut out and lose power. It will chug, cutting in and out for a few seconds before picking up. This also happens randomly when going up an incline. We have been put in a few dangerous situations by this before but thankfully nothing serious has happened. Took it to Ford dealer where we bought it and they told us nothing was wrong. We took it back 2 more times and still was told there is nothing wrong. I called today to get the truck back in and they say there is no record of us taking the truck in the previous 3 times.
I own a 2011 F150 3.5L turbo ecoboost truck. It has cause me nothing but grief! violent hesitation/shaking on highway when passing. Lose of power with engine light coming on left me on the road twice. Finally engine block exploded with a rod shooting out of engine. Oil spayed all over engine creating thick black smoke and poor visibility. Pulled over had to get out of the truck because smoke was inside. Countless Ford attempts to fix the issue and nothing worked. Eventually the whole engine was replaced. I just received my truck back and have lost total faith in this product. There is something wrong with this engine! I have all documentation for this.
I was reading on line about the problem with the Ford F-150 eco boost engine and realize that this has happen to me several times and scare the [xxx] out of me. Not realizing that there was a problem with the truck. As a matter of fact when I try to use the passing gear to pass the truck fell on it face. I would like this to go on a report of engines losing power during hard acceleration such as when passing. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
Dates and mileage are close but aprox. This is going on now and Ford has been unable to fix the problem after being in for repair multiple times. This is a constant problem with truck now. The first occurrence I was taking off from a light and went to accelerate and truck started hesitating and check engine light came on. Ford said it was intercooler and fixed that but drove truck from dealership and did not get 1/4mile down road before it hesitated again. Then Ford said it was coil pack and seemed to fix it but then it started right back up within a month.
Traveling on I 20 during heavy rain, got off interstate to refuel and after reentering interstate accelerated to get back to highway speed and truck stalled went to shaking real bad and engine light came on. Would not accelerate just shook real bad and I pulled over turned it off for a few minutes and restarted and continued on. No more issues once the rain stopped.
On I-70 near St. Louis, I was in the inside lane and when I press the gas pedal to pass with my F-150 ecoboost, the truck lost power and had almost completely shut itself off and the check engine light came on. I had to shut it down and let it set for almost 20 minutes before it would restart correctly and check engine light would go off. By luck I had enough room to move over on the median of the highway.
I recently saw where the NHTSA was investigating performance issues (bogging down, hesitation) of Ford ecoboost 3.5L V6. I have had this problem along with severe downshifting when decelerating causing skidding and loss of control in wet or icy conditions. I reported this problem to tony frederick vp Ford customer service who sent a factory rep to look at this and other issues. Was told vehicle was functioning normally. The hesitation when accelerating for me occurs regularly. I do not believe its isolated to wet or humid conditions.
Slowed down to make a turn, tried to accelerate and engine hesitated for five seconds. Tried to merge into trafic and engine hesitated. This has happened many times, had to pull over on shoulder till engine picked up speed.
After 4 hours of steady highway driving upon attempting to pass a vehicle the truck failed to downshift, lost power ( requiring me to abort maneuver) and began bucking... there was no cel. Took the car to the dealer and they inspected the truck found no codes and said no problem found. They said they reloaded the programming for the transmission. This vehicle has experienced this problem numerous times since the first occurrence. Always happens when accelerating and creates dangerous loss of power at critical driving periods.
Driving on interstate. Attempted to pass slow moving vehicle. Truck shuddered and lost ability to accelerate. This has happened several times. Dealership has been unable to fix problem, and has just reprogrammed computer each time. They now say that it's an intercooler issue. Was told part is on backorder, and would be in by end of April. Have attempted to contact them re: Part availability, with no response, and it's now May 23rd. This truck is dangerous, and has left me on the side of the road more than once.
First, this has happened many times, I would guess at a minimum 20 times over the past year or so. The date an mileage listed are estimates about the first time this happened. What usually happens is that I am waiting at a stop light and my vehicle will shutter as if it were about to stall and will then get a small burst of power and jerk forward slightly. As I mentioned, this has happened multiple times, and I always thought that my foot had come off the brake because of the jerking forward. I recently realized this was a problem when I heard about other people having similar issues.
The contact owns a 2011 Ford F-150. The contact stated that while driving 60 mph, the check engine warning light illuminated as the steering wheel shook violently. The vehicle also lost power and decelerated independently. The contact was able to restart the vehicle and as it proceeded to perform without further incident. The vehicle was taken to a dealer for diagnosis but they were unable to determine the cause of the failure. The manufacturer was notified of the failure. The vehicle was not repaired. The failure and current mileage was 41,000....updated 07-15-13 the consumer stated the manufacturer advised to continue to drive the vehicle until the failure recurs then, immediately take the vehicle to the dealer in order to record any codes that maybe stored.
