While traveling at high speed on the interstate on Thursday, my 2017 MDX dashboard lit up like a Christmas tree and stalled out such that I had to coast off the to the shoulder and get towed. The errors included Electric Parking Break Error, Emissions Error, Transmissions error , etc. but, naturally, the errors were gone when the mechanic checked it out and, for some reason, there was no computer record/history that these errors had occurred.

Ultimately, I was able drive the car home, but then it happened all over again yesterday while waiting in line for a car wash. I took a quick video, but I cannot seem to figure out how to post it here.

Any assistance/guidance is appreciated ...

 

I would not be surprised if it had something to do with a weak battery (12v).

 

I think I saw a TSB on that symptom, it involve a fuse or CB or relay that Acura found to be the cause. I can't find it now but your service advisor might help find that TSB.

 

Thank you.

 

I found it! It is TSB 19-005 titled "Multiple indicators on and optional fuse (E21 or B7) blown" I copied the symptoms below

Wow. Thank you!

 

There's a fuel pump recall for these and TLX's... (S/B 19-011) I would bring it to Acura if you haven't had that done. There's a software update and if it stalled and set an on-board snapshot for 'Engine Stall 2' it also needs a fuel pump.

S/B 19-005 doesn't apply as stalling is NOT one of the symptoms listed.

 

Acuratech thanks for sharing that. Sounds similar to a stalling problem my mom had with her 2016 V6 Accord when it was a year old. Sure enough, same bulletin exists for the Accord:
