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.

When I go to accelerate it periodically has had an issue of selecting the gear. Sometimes it has held onto 1st gear without changing to second, most recently it has been skipping from 1st gear to 5th gear. I've recorded a video (link at the bottom) to better demonstrate. I drive the truck in a humid environment (oahu) + wash my car regularly (nothing in the engine, other then spraying the grill) - as I've heard of similar related issues. I've uploaded a video of it to youtube which was recorded yesterday after trying to accelerate at a stop light (I had tried to troubleshoot it 3 different ways after pulling over - 1. going into the low gears (1, then 2), then drive 2. I tried manually telling the vehicle which gear I wanted to be in (it blinked to indicate I'm locked out) 3. (as seen in the video) I went to park, then to drive

In damp conditions the F-150 with the eco boost engine has a severe vibration and loss of power problem when the turbo chargers are called for. In otherwords when you strongly accelerate to get on the highway the truck dies.

I was merging on the on ramp to obtain highway speed I stepped on the gas when all of the sudden the truck started to shake really bad. I tried to step on the gas to accelerate but there was no throttle response to the engine as the truck continued to lose speed. Every time I tried to step on the gas the truck would shake even worse. I pulled over to the side of the road so I would not cause an accident. This is not the first time I have experience this shudder in the truck.

While driving in the rain I attempted to merge onto I-74 near indianapolis, in. The ecoboost engine lost power and the "check engine" light came on. The truck shook and vibrated like the engine was only running on a couple of cylinders and had virtually no power. We were nearly rear-ended by a semi that we were trying to merge with. I drove very slowly on the shoulder for an extended time as there was no place to get off the highway. Finally it seemed to regain power and we headed on home to Illinois. The check engine light stayed on.

The contact owns a 2012 Ford F-150. The contact stated that while driving 50 mph, there were abnormal noises heard from the engine. In addition, the vehicle remained stuck in second gear. The contact stated that the failure was most prominent when there were moist, wet weather conditions. The vehicle was taken to the dealer for diagnostic testing, who stated that the irregularities where a characteristic of the eco boost feature. The manufacturer was made aware of the failure. The failure mileage was 1,500. The current mileage was 10,463.

While driving at approx. 70mph I attempted to accelerate hard to allow another vehicle to merge into traffic on southbound I-75. My vehicle immediately slowed down and began to shudder. I let off the accelerator and coasted until the shudder stopped. The steering wheel shook as if I had two flat front tires. The vehicle returned to normal after about 30 seconds and I completed my trip without further problems.

While driving on an interstate with two motorcycles in the bed of the trucks, the truck started to shake and vibrate. Have since seen this referred to as the shudder that sometimes precedes the limp mode which results in power failure. After changing lanes and monitoring tires on nearby vehicles in motion we confirmed it was not the road. I have since experienced it again but cannot recreate the behavior on demand and it seems to be only on long trips with a load in the truck.

Truck stumbles and stutters at 62 mph and around 1400 RPM when attempting to accelerate. Ford dealership replaced cac and upgraded software, this helped the problem but did not fix the problem. I reported back to the dealer about the continued problem and there response was that I was feeling turbo lag and Ford Corp does not currently have a fix, check back in a few months.

Ford F150 crew cab - lariat - V6 ecoboost engine. Problem occurs when not towing, not engaged in 4X4 mode and occurs randomly in wet, damp and dry conditions. Driving at highway speeds (60) on a 70 mph highway, tried to accelerate to pass semi truck and truck shuddered and would not accelerate at all. Speed dropped dramatically and we were almost hit from behind. Only method of getting truck moving was to stop on the side of the highway and let the truck sit, turned off for 2 - 3 minutes. It took 5 or 6 of these stops to get to the nearest Ford dealership, where a tsb was referred to and it was suggested by the dealership that we continue on our vacation and stop in tallahassee to have a larger dealership take a look. The tallahassee crew updated the computer and provided a report for bill currie Ford in tampa, to install a shield of some sort once we returned, as they did not have the part in stock. Bill currie service reported that the shield was already in place when reported a few days later. The truck was taken to bill currie Ford a total of 5 times for the same problem with the final time to have a Ford tech do the work. The problem persists. Overall the truck is less than it was advertised. I got 18.7mpg with my previous 6.2L F150 and I have yet to get more than 17.8 on the ecoboost. Around town I also get much lower mileage (11.7mpg as opposed to 14.9 with the 6.2L engine. The shudder/loss of power occurs randomly and has resulted in near crashes at least 5 times in the months since we purchased the truck, all at highway speeds.

V6 ecoboost my family and I were traveling in heavy rain on I65 in birmingham, al. I pulled into the far left lane to pass slower vehicles. When I accelerated the truck began to shake violently and rapidly lose speed and power. Several vehicles including a semi had to take evasive action to avoid a collision. The second time was on my return trip home. We were traveling on a two lane road in foggy conditions. We came to an area when the road split so you could pass slower vehicles. I, along with a car following, went to pass a slower vehicle which had moved to the right. When I was alongside the slower vehicle my truck began to shake and lose speed. I had to take evasive braking action to fall in behind the vehicle to my right because they were running out of room. The vehicle following me also had to take evasive action to avoid hitting me. And the car to my right. I took the truck to the dealer when I returned home. They replaced the cac, installed a plastic shield, reprogrammed the computer, and replaced a defective cat as was the recommended repair according to the issued tsb. On April 18th I was traveling on hwy41 in the rain.twice on my trip the vehicle began to shake and lose speed when passing slower vehicles. The applied tsb did not fix the problem. I returned the vehicle to the dealership at the request of Ford customer care. They were unable to find an issue. The day the vehicle was returned the second cat went out and had to be replaced. Ford has acknowledged the issue but has informed me that there is nothing they can do at this time. They offered to send me a buy back offer within ten days and after twenty days and several phone calls today they informed me that they are unable to buy back my truck. They also told me that I would have to live with the issue until they (if) come up with a fix. I am unwilling to put my family at risk.

I have experienced two separate occurrences where the truck would violently lose power during acceleration during rainstorms. The first time the check engine light flashed but went away. The dealer told me it was probably the traction control, since no check engine light was logged in the system. The second time was April 24th, 2013, and the truck had approximately 11,000 miles. I was traveling approximately 70mph and passing two 18 wheelers on the interstate during a heavy rainstorm and the truck began to misfire and stutter and had no power. I had to swerve between the semis and coast to a stop on the shoulder to narrowly avoid a potentially fatal crash due to the loss in power. The check engine light stayed on this time, so when I took it to the dealer I specifically asked about the turbo intercooler issues that the ecoboosts have been reported to have. After checking my truck out, they indicated that my problem was consistent with the interrcooler condensation issue, but that my truck was built with the newer updated intercooler and that there is currently no fix for the problem. Now I am the disappointed owner of a new truck that I'm afraid to drive in the rain because my family might be killed or injured in it. The truck was purchased and always serviced at premier Ford in columbus, ms.

Traveling at 60 + / - mph and attempted to pass another vehicle under normal conditions. Engine lost power on acceleration and seemed to sputter. This is strange as the gas was not "punched" or anything outside of normal passing acceleration. Initially I thought I may be out of gas or something but this was not the case. I have noted power loss two other times but did not think anything of it as the engine returned to normal once I backed off the gas. The one difference this time is the engine made a very rough vibration which caused others in the truck to ask if I was having engine trouble.

Straightening our vehicle in parking place at home depot. Slowly (~2mph) going forward with foot on brake when engine suddenly speed up. Mashed down hard on brake while shifting into neutral. Tires or clutch screaming so loud it drew a group of yardmen unloading a truck nearby. Shortly after getting it shifted into neutral engine resumed normal operation. Took to Ford dealer immediately and will be evaluated after the holiday. Several times in the week prior to incident I noticed some slight "stuttering" of the vehicle when slowly moving forward to park in driveway, also noticed for the past 1 to 1.5 months there has been a 2+ mile per gallon decrease in fuel mileage running over the same routes.

While merging from I-26 to I-20 while pulling a lightly loaded cargo trailer I was accelerating down the entrance ramp, had just begun to merge and suddenly with no warning my F-150 truck with an ecoboost engine began to hesitate.... actually is was much worse than a hesitation it seemed to lose all power and began to vibrate terribly (felt and sounded like driving on a corrugated/washboard road). I had a large 18 wheeler closing in very fast, I actually moved to the emergency lane to allow him to pass. Very scary! the weather was rainy and humid, this incident could have ended badly. I had one passenger at the time that witnessed this event.

While driving at 65 mph on NY state thruway, with cruise control on, towing a trailer with one motorcycle, vehicle was in tow/haul mode. It was moderate rain. The truck shuddered, lost power momentarily, flashed several error messages on the information display, and resumed driving but now the vehicle would not accelerate over 60mph. Upon pulling off the road into a service area, I shut off the vehicle and restarted it. Errors were cleared. Resumed travel on the interstate. Went about 2-3 miles and it did it again. Limped 30 miles to next service area. Shut it off. Restarted. My aftermarket gauge cluster and code reader was showing errors P012B, P012D, P0106. Drove the remaining 200 miles at 55mph. Problem did not repeat.

I was merging into traffic on I-10 in Florida from an entrance ramp. I was going 55 mph when I had to accelerate in order to merge with traffic. Upon attempting to accelerate, the engine lost power and began to shake causing me to have to brake really hard and move to the shoulder of the road so that I wouldn't collide with traffic already moving at 70 mph in the lane I was attempting to merge. This is the first of several incidences in which the vehicle lost power under acceleration.

  • 13,300 miles
I was driving on a 2 lane highway, behind a semi truck, with several cars behind me. We came to a passing zone and I began to pass the semi truck. I moved to the oncoming lane and accelerated, but the truck lost power. I began slowing down in the on coming lane, but couldn't return to the right lane because the vehicles that were behind me were passing me in the right lane and I had a vehicle directly behind me that was followed me to pass the semi truck. I locked out 5th and 6th gears on the transmission to gain some RPM but the vehicle started to shudder violently. I moved to the shoulder of the on coming lane and shut the vehicle off. I sat on the shoulder for several minutes, got out of the vehicle and checked under it for fluids. There were no fluids under the vehicle. All the gauges read normal. I did all this on the shoulder of the oncoming lane facing oncoming traffic. This was not a good position to be in. I started the vehicle, put it in gear to see if it would move, it did. I had full power and got back into traffic and the truck ran fine. No warning lights, no indication that anything was wrong. Several miles later I lost engine power again, and again got the violent shudder, and the check engine light came on. Going to see the dealer today. This is bad! the first incident could have caused a huge accident. Moving onto that left shoulder proved to be a good move, but I was at pucker factor 10 for a few seconds.
