I have a 2014 Expedition XLT EL with 186k on it. The Service AdvanceTrac notification has been coming on intermittently. The ABS, TCS, and Stability Control lights also all come on. They all turn off as soon as the Expedition comes to a stop. The mechanic says it isn't throwing any codes, so they don't know what the issue could be. Any suggestions? I really like this SUV and would like to fix whatever the problem is before it gets worse.
