2015 christmas tree dashboard (resolved)

[ldp82]

2015 5.0 Ultimate just turned 50k miles today. To celebrate it had a meltdown throwing the check engine, stability control, PSB, TPMS, AEB, autohold (now disabled and in red) and I think briefly the airbag light. When I came to a stop it ran rough for a few seconds before shut down. on restart an hour later just the check engine light was on, car ran fine for 1/2 mile before all the lights returned.

Called the dealer and will be dropping it off first thing tomorrow. I think its a senors and hope it is an easy fix.

While it's not impossible that a whole bunch of completely separate sensors associated with those separate systems all failed and recovered at the same times, it seems much more likely to me that it was/is some system wide failure such as power supply (alternator/battery) or something interfering with a car wide data bus.

This is commonly a single module failure, the highest likelyhood of which is the fuel pump control module in the back seat. It causes a CAN interruption which makes the instrument cluster think it's Christmas.

Thank you both. On the way into the dealer parking lot the car had another hiccup. Thankfully I was able to show them! In addition to all the lights the engine temp and out side temp both failed to register and the car started stuttering. What was very odd is when I put the car back in drive the shifter light stayed in park (car still drove). I informed them about the fuel pump module and am waiting to hear back.

Another symptom of bus (CAN) failure. It could be wiring, but it is often a failing module, like the fuel module or the parking brake module, or some other one.

Closeing the loop on this one for the next guy. You were right, confirmed fuel pump module.

Glad that you identified the issue.
What's the damage ($)?
