2011 Ford F-150. Consumer writes in regards to vehicle blend door actuator malfunction. The consumer stated when the blend door failed, the HVAC system would blow hot air into the cabin. The consumer stated the cause of the problem was the blend doors gear teeth becoming brittle under normal working conditions and shearing off, which prevented the actuation of the blend door and then it became spring loaded to a full temperature condition. The blend door failed on four separate occasions.

We bought 2011 Ford F150 XLT supercrew cab on October 25, 2014. Last Wednesday night, November 5, 2014, I was driving home with our two kids and turned on the rear window defroster. The light indicator didn't come on quickly. A minute or so later, popping noises came from the back cab and found out that rear right window was shattered (the right side of three pieces rear window power sliding system). Faulty rear window defroster might be the cause. Waiting for dealership to see if their 90 day warranty will cover windshield replacement.

I started my vehicle on the morning of Feb 8th, and turned on the rear defroster. Within 1-2 minutes I heard a pop noise and found the glass panel behind the drivers side (one of 3 glass panels) had shattered. No outside impact, it just shattered. I see doing an on-line search there are similar complaints of this problem. I contacted Ford Motor Company and was told seeing as I was out of basic warranty, they would not be able to assist me with the cost of repairs. $625 + tax.

Well I have an issue with my trucks I have purchased from Ford. Well in August of 2011 I purchased the new F150 with ecoboost. The truck drove like a dream for a while then I started having issue, with the transmission, then engine losing power. This happen about 4 time during the life of the truck.the last time was in January 2013, it was the last straw for me. The reprogrammed the trans/computer and put a wind deflector in the front of the intercool. Still lost power on a road trip on the way back home from S Carolina. Mind you the truck was in the shop for tran/engine/the right fender had to be adjusted it was misaligned, the bed of the truck same thing. This lost of power almost caused me to have a accident because I was merging onto the highway. I also had to sunroof replaced as it was vibrating the whole truck when moving. The driver seat track was replaced and the sliding glass window in the back was replaced too. The defrost stopped then the window stopped sliding. I stopped driving the truck so I could get rid of it I have a 2013 limited and have some of the same issue. Now that I have a new 2013 vehicle I experience some of the same issue.

Drivers side rear view mirror vibrates excessively when radio is loud or when driving at highway speeds. Makes headlights appear blurry or flashing like emergency vehicle at night. Dealer said Ford would not pay for new mirror assembly. Have had them look into it twice. Upgrading the complaint to the next level with Ford.
