Hi I have a 2015 Acura TLX with the tech package the six cylinder and I’ve got a warning saying that I have a problem with my emergency brake and also an emissions problem warning. I don’t know if these two are related but I’m very confused if anybody has any answers, please help. Thanks!

Are you still with your original battery or has it been replaced. Quite often (but not always) the original battery (being now about 4 plus years old) will cause 'gremlins'. I also drive a 2015 and just replaced my battery.

The tech called me today and said that he is replacing a secondary oxygen sensor. I believe that he has absolutely no idea what the actual problem is and is just spitballing. I'm starting to feel that this TLX purchase was a seriously bad mistake.

Actually, I think your technician is probably on the right track.

When I replaced my exhaust with a high-performance one, it took me a few months before I was able to get an intermittent check engine light from coming on. Each and every single time, the emergency brake warning light came on at the same time. At no point did I ever touch anything regarding the e-brake, but once I got the emissions system squared away, the e-brake warnings stopped too. My money is on a bug in the system somewhere that causes it to fire mistakenly. There's some others in the forums here or at acurazine that have reported the same issue with the two warnings firing at the same time.

My light was coming on because with the new exhaust system, there was much more airflow coming by the O2 sensor. It stands to reason that a bad sensor would cause the exact same problem.

You guys are right. I am wrong. The tech is probably on the right track. I'll get the car back tomorrow. They have me in an RDX as a courtesy vehicle. My complaints are unfounded. You guys are totally right. It's just one little thing. My bad.

Sweet thanks interesting in how they resolve your issue. I think the dash indications can be more than one type of issues with the same display.

The technician replaced an oxygen sensor and the lights were off. Picked the car up Tuesday night (10/30/18,) it's now Thursday and the lights are back on. Have an appointment this Tuesday evening, waiting that long because of courtesy vehicle availability. I am asking anyone and everyone who has experienced this problem: was it ever actually fixed? What was the actual problem, in your situation? Or did you just eventually trade the vehicle in? Any advice/words of encouragement would be highly appreciated.

I wonder if this can be repaired without parts t. I have heard of some fords having issues with dirt and debris getting in the cap less fuel filler and preventing a good seal. This would cause a small leak and they would throw a code for emissions issues.

Here is a video I found. I know it’s for a ford, but it would seem like this maintenance/repair would apply to most cap less fuel filler systems.

You may be onto something. I'm going to try it as it's that kind of basic thing that can cause folks to drop a ton of money as a "tech" (lol) replaces parts to solve a problem he/she doesn't have a clue about resolving. The filler tube assembly replacement has been the solution to this specific issue throughout a variety of years and models, which, if it is the root cause, is an engineering flaw for which Acura should be held responsible. This would be the ethical thing to do.

Service data entered at Acura dealers creates a database of mechanical tendencies by year and model. The compiled data would create the ability to fix owner issues quickly thereby securing brand loyalty and reducing cost of ownership.


I'm going to thoroughly clean my capless fuel filler, lift the negative battery terminal to clear the codes and I'll post back in two or three weeks with an update.

Cataclean and cleaning the capless fuel filler did resolve the issue. Off to the dealership.
Sorry to bother you, but would you please clarify if it did or did not work?
I'm assuming it was a typo because if it did work I don't believe you'd be going to the dealership.

No bother... sorry for the typo! The Cataclean and cleaning of the capless fuel filler DID NOT resolve the issue. Since posting I was notified of a safety recall related to the fuel pump. Further, I received a notice about nine months ago that the Automatic Transmission Fluid warmer may be defective in some models and mine may be affected (they know **** well which vehicles were affected). The notification allows for the replacement of the engine and/or transmission should they fail as a result of the ATF warmer issue.

I have a general rule to stay away from first year models, but thought the TLX was established. Wrong again. I'm shopping a 2019 presently as my car was dropped off at the dealer today to resolve the emissions/parking brake issue.


My entire family: son, sister and mother are Honda loyalists. I may be losing faith.

Brought mine into the dealer for the same problem. The dealer flashed my computer system with a firmware update and the problem went away. They were able to cover it under the 60,000 mile powertrain warranty ...not sure how they did that but they did.

Same issue on a 2019 tlx with 180 miles. Dealer said it was a defective manufacturing weld on the exhaust system. Fixed in a few hours. They have been very responsive. In my 30 years of acura ownership this is the first real issue I have had like this.

I just took my 2015 TLX to the dealer and they are telling me i need the mass airflow sensor replaced. However, my car isn't showing any signs of a failing MAF sensor.
