Gas Recirculation Valve (egr Valve) problems of the 2011 Ford F-150

Follow up to complaint listed below (beginning with summary): it should be noted that this incident did not occur in humid or rainy conditions. This incident did not occur while travelling at highway speed or wide open throttle. This incident occurred while starting from a complete stop under light acceleration turning left across traffic. Vehicle lost all power and would not move. Pushing the gas pedal did increase engine rpm but vehicle would not move. The behavior exhibited by the vehicle sounds very similar to the condensation problem I have been made aware of with the 3. 5 v6 ecoboost. However none of the circumstances Ford claims causes the issue existed. This is an extremely dangersous condition. Weather was approximately 15 degrees and sunny. I have experienced the problem when the vehicle has been cold and after it has been running for a while. Summary: while attempting to cross oncoming traffic lanes to access interstate vehicle began to move then suddenly lost all power. Rpm's went up to 4000 rpm but vehicle would not move. Vehicles were approaching in excess of 50mph. I managed to barely avoid being struck by oncoming traffic and pulled to side of ramp. Vehicle then began to move again. Took vehicle in for service. Dealership performed two fixes involving some form of air dam. On 02/24 vehicle did the same thing luckily in a parking lot this time. This is an extremely dangerous condition which leaves no error codes so far. I am seeing many similar complain ts online. Taking vehicle in for service again on 3/3/15 as the issue occurred again today 3/2/15.

On February 13, 2014, my Ford 2011 F-150 ecoboost began to show signs of limited throttle response coupled with a drastic reduction in power output and moderate to severe engine vibration. These symptoms occurred and were most severe under heavy engine load, while traveling uphill, high outside air temperature and with the air conditioner on. General locations: mojave high desert (joshua tree, CA) and the greater palm springs, CA area. Weather conditions were generally dry with low humidity. On February 15, 2014 the symptoms described above were so violent that the check engine came on (flashing) and I pulled off the road for my own safety. I shut off the engine, allowed it to rest¿� and then turned the engine back on. The symptoms did not disappear completely, but they were reduced and the check engine light was no longer illuminated. On February 20, 2014 I brought my truck to yucca valley Ford to have the problem diagnosed. Mileage at the time of the service was 68,382 miles. A diagnosis was performed and it was determined that the engine was misfiring on the number 1 cylinder due to worn spark plugs. All 6 spark plugs were replaced and the symptoms disappeared. The truck ran fine until approximately June, 2014. The symptoms slowly began to reoccur and by early August, had fully returned. On August 8, 2014, while traveling at freeway speeds, up a steep grade, with external air temperatures in the low 100 degrees, low humidity, and the air conditioner on, the truck nearly lost all power, began to misfire and vibrate violently, and the check engine light began to flash intermittently. Upon reaching the top of the grade and the load on the engine reduced, the symptoms were reduced. The truck was again brought to the yucca yalley Ford service center on Saturday August 9, 2014 where it is currently awaiting diagnosis.

I was driving in highway traffic in the right hand lane at about 70-75 miles per hour. The weather was clear and the temperature was approximately 50 degrees. I encounter a slow moving vehicle and moved into the left hand lane and tried to promptly accelerate to pass a slower vehicle. When I attempted to accelerate the vehicle began to shake violently and go into a very rapid deceleration. The violent vibration of the entire vehicle and rapid deceleration made control a challenge. I moved to the right hand lane reduced speed to 50 mph and continued on to a Ford dealership to have the vehicle evaluated. The dealership found that 3 coils failed which caused the vehicle to vibrate and decelerate rapidly. I had the vehicle repaired.

We were merging onto the highway outside of st. Louis mo and when the accelerator was fully depressed the engine started to misfire and power was reduced. A blinking cel was displaying on the dashboard. It seemed as though the turbo system was not adding any extra charge to the ambient air. There was a pronounced vibration to the vehicle that seemed to originate from the engine/drive train. Luckily there as not a lot of traffic at the time and our poor acceleration did not result in an accident. My solution was to manually select the gears and drive at much higher rpm. This smoothed the misfire and we had an adequate amount of power to keep up with traffic. After about 10 minutes everything smoothed out and the misfire was gone. Truck behavior returned to normal. The weather that day was a pleasant 60 degrees and sunny. The previous day we drove from central ohio to st. Louis through much rain and fog. Since we were on vacation and away from home we did not take the truck to a dealer to be serviced. The problem has not occurred since then. There was one previous occurrence at a previous date. I don't know exactly when it was. We were traveling home to vt from ohio. We had been driving for many hours, mostly on highway/cruise control driving. We had just gotten off the interstate highway and were on state highway. I went to pass a slower vehicle in my lane and upon depressing the accelerator the engine seemed to misfire (rpm went up but power delivery fell flat). I stepped off the gas pedal and slowly pressed a second time and this time the truck responded as expected. There was no cel this time. Each of these incidents occurred with my entire family in the vehicle. We were not very happy about it and did not feel safe at the time.

My truck is equipped with the ecoboost 3. 5l engine. Twice now I have attempted to accelerate and had the truck lose power and shake violently, creating a very dangerous situation. The first time was attempting to pass another vehicle. Weather conditions were warm (75 degrees f) with light rain. I pulled out to pass and attempted to accelerate when the truck suddenly acted as if the gas was shut off. It then began to shake and shudder violently as if the rear axel was being ripped from beneath it. I was able to fall back behind the vehicle I was attempting to pass, out of the way of oncoming traffic, and pull to the side of the road. After shutting off and restarting the truck, it seemed to run normal. The dealership service tech inspected the truck and stated it is a problem Ford is aware of (in wet conditions), but has no fixes. The second time I was attempting to enter the interstate from a rest stop into a single lane construction zone. The weather was cool (45 degrees f), dry and sunny. I attempted to accelerate to enter the highway and the truck acted as it did on the first instance. I was forced to pull off of the lane between two large construction pylons in order to avoid being struck by a tractor/trailer. The supplied dates, mileage and speed were from the most recent incident.
