Traveling on i-15 freeway in southern california, going 70 mph on cruise. head a loud "bang", pulled over and saw damage to underside of vehicle and fluids leaking. transfer case appeared to be split open. towed to mojave ford dealership in barstow california, where repairs were made. description of findings is attached below. problem seems to have originated in the 4wd system. truck was in 2wd in the cab, however vacuum hubs were in 4wd. mechanic stated that this is a problem with ford trucks. no recall on file. post repair, the truck still stays in 4wd when reverting to 2wd from the cab. operator is required to manually put hubs into 2wd.
The ignition sometimes turns off by itself. when attempting to start vehicle the ignition will get stuck in the far on position. if you don't notice this and start to drive and hit a bump the key will spring back to the off position causing power loss. the key also gets stuck in the ignition and not able to remove it. this has been going on for awhile and have not seen any recalls on it. today i started my vehicle and did not notice the key stuck in the far on position. i drove away from y residence and hit a small bump in the road. the key went back to the off position and my vehicle stalled in traffic. luckily i realized what happened and pulled over to restart vehicle. once i got to my destination the key would not come out of ignition.
When attempting to start the vehicle. the ignition switch gets stuck in the on position and does not release to the normal position. getting stuck causes the heater and the radio or any other electronic device inside the vehicle not to work. to make these devices work, you have to manually turn the ignition one notch towards the driver. this happens all the time when attempting to start the vehicle.
While driving my 2010 ford f250 super duty on the highway i drove over a bump in the road. the truck began to shake violently. it felt like it was going to fall apart while still in motion. i tried to hit the brake but that seemed to exacerbate the problem. i tried to adjust the steering wheel in hopes to align some defunct component. nothing seemed to help except to let off the gas and attempt to control the vehicle and avoid a potential fatal accident. this really was a frightening event, it was all i could do to maintain a safe distance around me so not to collide with other drivers.
