I see there is a closed thread from Spring of 2015 that exactly explains my situation.

I have a new 2017 TLX, with 1,800 miles on it.

I suddenly got a simultaneous warning on the dashboard screen of an emission control problem and a parking brake malfunction. Both show up with a bright alarm. It was preceded about 15 miles prior with a sudden freeze of the car whil pulling out of a parking space going less than one mile per hour. The car seemed to have gone into "park". The car transmission did not work. I turned off the car, then restarted it and it was back to normal. I drove 15 miles, then got the two simultaneous messages. I drove directly to the Acura dealership.

The Acura dealer said they reset things and the warning lights went off. They reported to me they had anomalies shown in the computer but that since the car now seemed to be working there was nothing more to do. They made no mention of this forum, nor of the proposed fixes of fixing a fuel filler part or replacing the catalytic converter.

It seems weird and troubling--two simultaneous warnings for apparently unrelated systems. I wonder if the sudden stop is related to the two warnings, and if this will be a recurring problem.

With as many sensors, computers, switches and such I’m surprised there are not more electronic gremlins. Remember Windows XP and all the problems it had? Even after Window XP, there was Windows 95, Windows 2000, Vista and more each with their own peculiarities such as blue screen of death. What did we do when that happened? A reset.

Hmmm. I don't know about that analogy. A car suddenly stopping, freezing in traffic, throwing all kinds of warnings, that's alarming and dangerous. A dealership needs to take that much more seriously and do some diagnostics.

I agree, Slimm. It is exactly what happened to a couple of other people. One said it was fixed when the dealership replaced a fuel filter or something and another guy said it required a new catalytic converter. Jeeze. But it was the same syndrome, a n emission warning and a parking brake warning. It would tear things up pretty badly if the car goes into Park intermittently. Peter Sage

I wasn’t trying to make light of what happened. My point was that; on occasion working as a line technician, you will receive a vehicle with an intermittent/unusual problem; that checking the code history, scanning the range of the sensors and then finding out that all is reading correctly; well, what part do you replace? You just spent 30 or 40 minutes on this vehicle. You’re not finding any bad sensors or parts. Acura is very picky about paying for warranty diagnostic time without replacing a part or you can unhook the battery and reset all the computers and see if it comes back without wasting too much more time that you are not getting paid for and call it a static electric gremlin. I’ve seen techs replace random parts that you would never think could be the part in question (often just to justify their hour or two of diagnostic time).

The bottom line is: the more this problem comes up; the more people take their vehicle in to an Acura dealership for it; the quicker there will be a TSB about it to all the dealerships so that it can be fixed. In the meantime, expect to see to see all sorts of different guesses on what is causing this intermittent problem.

There appears to be numerous complaints about the EPB (Electronic Parking Brake) not disengaging. Here is the actual NHTSA complaint.

INVESTIGATING CUSTOMER COMPLAINT OF THE ELECTRONIC PARKING BRAKE NOT RELEASING AND CAUSING ONE OR BOTH REAR WHEELS TO NOT MOVE.


Appears Acura is replacing the EPB assembly in some situations.

Odd that no one has reported having the parking brake replaced here in the forum. I would have thought we had seen most of the more common issues.

I had the same thing happen Saturday evening in my 2016 TLX SH-AWD. Driving on interstate, up a hill and it was like my car suddenly went into neutral with several warning lights flashing. After a few seconds, I could accelerate again, so I pulled over turned the car off and back on. It drove normal after that, except the alternating warning lights for emissions system and electronic parking brake. My dealership said the only code they could see in the system was 'lost communication' and that everything checked out normal after they reset it. Been really happy with the car, but this was concerning.

What models do you guys have who are experiencing this issue? Really hate alot of this electronic sensor crap, and this kind you can't ignore because it interferes with actual safety

My 2015 Acura tlx just did this as well.. bought it with 39k miles put 2k on and it won’t go away now.. really hoping this isn’t a serious issue. I did not go with the extended warranty do you guys know if the 5 year manufacturer warranty would cover this?

Yes it should assuming something failed you didn't drive over a Prius or Lime Scooter. Have the dealer look at it.. you warranty is good for 5 years 60,000 miles. (as my memory recalls).

Let us know how you make out with this issue, but don't wait, have them look at it sooner then later.

Okay good they said they were going to charge me 175 just to run a diagnostics over the phone so I'm hoping that I don't have to pay anything for this fix as I don't believe I should with such low miles

I am taking it in tomorrow luckily the warranty still covers this! They are going to give me a loaner and also check out the vibrating issue.

What is the cause? I bought a brand new 2019 TLX 2 days ago. Happened tonight. 170 miles on the odometer. It disengaged after 5 minutes. Took it to my 30 year relationship dealer. Got a loaner. They said it is a fuse problem. Is it? This is my 6th Acura I still have my 2010 rdx with 212000 miles. My first real issue in 30 years of ownership.

I have the same problem with my 2016 Acura TLX. Two warning signs come on suddenly. It disappears next day but come back on a couple of day later.
