I purchased a new 2015 Ford F150 Lariat 4wd January 2015. In a very short time I started getting warnings for Service advance trac, Check rear park aid, ABS etc. My truck was in the dealership enough to institute the Lemon Law here in Illinois. Ford could not identify the problem but decided to replace all the sensors and computers. My truck was gutted for that. Glad I purchased an extended warranty because a week ago I Now have the same warnings. Anyone else having this?

 

Holy Smokes is all i can think of!

 

Talk to a lemon law lawyer.

 

I agree with NotBlake. You could consult the problem to Lemon law lawyers. I have also just read about this matter at https://www.lemberglaw.com/lemon-law-lawyers-attorneys/. Might be useful for you.

 

Check the wiring harness on the drivers side near the turbo. Several have had issues similar to yours and the harness was damaged at that point.

 

Sorry I have been slow in replying. My truck had a faulty left front wheel speed sensor and it was replaced. It is amazing that it caused so many different alarms and warnings. So glad I purchased an extra warranty!
