I have a 2016 Acura TLX SH-AWD (approx. only 14k miles) and just about a week ago the three braking system problem lights came up on the dash ("Brake System Problem", "Brake Hold System Problem" and "Electric Parking Brake Problem"). I took to a local Honda specialist who ran the codes and stated that probably a rear emergency brake got stuck (due to underuse). He cleared the codes and said if it happened again, to take it to an Acura dealer/service. It came on a few hours after that and has been on ever since when running the car. There are no obvious issues with the actual braking system (it drives/brakes fine) and the brake fluid is at a perfect level. Any thoughts? Taking it to Acura tomorrow to get it checked out. Of course, my car is JUST outside of warranty because it was purchased in May 2016 (4yr/50k).

Just out of curiosity, have you changed the battery on your car yet with it being a 2016?
I only ask because these cars seem to have electrical issues as the battery gets weak over the years, and the parking brake is electronic.

No issues with the battery to my knowledge. Dropped off at Acura this morning and after some diagnostics, they found the parking brake actuator was bad. Sad for a car with only 14k miles....

I had the same issue last year and took my 2015 TLX to the dealership. The battery was weak and they charged it up and the problem was solved. A few days ago my TLXs dash lit up again with the same alerts. I’ll try charging it up before I take in to the dealership. Who knows what they’ll charge me for.

I have a 2015 TLX base and this problem came up. I was fearful it might be the rear toe control actuator issue on TSB 15-050, and my car is in the VIN range of that problem source, but it seemed odd I would get this several years into its life. The subject of this post was the other potential root cause (and hoped for, based on cost), and upon close inspection I found the positive battery terminal was a little loose and generally a mess. After replacing it and trickle charging my battery all the warnings went away. It took a bit for the car to feel better about - right after I finished and started the car all warnings were still present, but during a subsequent drive they cleared. Thank you for starting this discussion, as you saved me a trip to the dealer.
