i have a 2009 f350 6.4L diesel i had an oil leak had it fixed under ford warranty and now i am experiencing alot of problems since they put everything back together. since i got it back when im at a stop light withmy truck in drive with my brake pedal pressed , i have a vibration in my steering wheeel and can feel it when i have my arm on the middle console. the warm the truck gets the more the vibration only in gear at a stop cant figure it out nor can the dealership. the hard i drive it the more vibration at a stop, and the louder the engine or something sounds inthe floor. if anyone can help or if they have had this issue or have it please let me know. Also since this repair when i start my truck first thing in the morning whne i crank the engine check brake system comes on for a few seconds and doesnt come on again all day. My theory is that when they pulled the motor out to fix the leak they damaged something line or mount maybe hydralic line for brakes dont know either does the dealership , but would like to get some feed back from anyone that has a suggestion or can relate to problerm.... 2009 f350 69000 kms

 

Have your batteries load tested. I think you have the tell tale signs of batteries that are getting weak

Check brake message is usally what shows first.

vibration issue sounds like injectors to me.
