2020 Acura ILX

On October 23, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25015 after receiving complaints concerning a loss of brake assist in 2019-2020 MY Acura ILX vehicles. These complainants alleged master cylinder failures resulting in soft pedal feel or the brake pedal intermittently going to the floor. These failures could result in extended braking distance increasing the risk of a crash. Honda found that residual plasticizer in the brake reservoir hose could contaminate the brake fluid. This contaminated brake fluid was then absorbed by the secondary cup seal, causing it to swell. Engine heat during operation could further expand the swollen seal, allowing brake fluid to pass. Brake fluid bypassing the master cylinder cup seals can reduce brake-pedal firmness and increase stopping distance. On April 08, 2026, Honda filed Recall 25V-859, recalling all 2016-2020 MY Acura ILX vehicles produced from October 9, 2014, to January 29, 2020. Under the recall, the dealer will replace the brake master cylinder with redesigned inner cup seals made of a different material, providing improved sealing capability. In view of Honda filing Recall 25V-859 addressing the subject of this investigation, ODI is closing this Preliminary Evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

I am experiencing an issue with my brakes. When I am at a red light and I brake, I find my brakes start to descend. So it's brake, then the brake moves a bit down towards the floor. Then it moves down a bit more. I am still able to brake but I find that the brake pedal moves down a few times while I am sitting at a red light. I am greatly concerned.

I live in a colder climate, we’re were experiencing temperatures in the 20’s with ice storms. While driving the rear window completely shattered, the rear defroster was on during the time of the incident. I contacted the manufacturer for a remedy, they informed me there is no remedy for my particular vehicle. They suggested I pay out of pocket at a certified Acura dealership to get a dignostic and to get the window fixed. I decided to have the window replaced by Safelite. There is a very big and well known problem with the 2020 Acura RDX for this same scenario happening. There was warning light or indication something was going on with the window. Acura needs to address the problem with the rear defroster as this poses a huge public safety risk when this happens while the vehicle is being driven.

My Acura ILX 2020 has less than 40.000 miles and has a mechanical problem that can not be fixed and it is dangerous for my self and others. In my opinion this is related to the stearing of the car and it is very dagerous knowing that you take your car to be repair and the dealer does not know how to fix it. It makes clicking noise when turning. It is a rattling type noise coming from what sounds like the front, right side of the car. I usually hear it over little bumps but as the day goes on the noise gets louder and the bumps do not have to be that big. I'm not a car technical person, but any type of noise coming from my car is concerning. Other people feedback "I've been to the dealership on three occasions to try to fix the problem. On two of the occasions I was put in an ILX loaner with the exact same noise. " It does matter of what parts is gets change the car keeps making a rattling type noise coming from what sounds like the front. Please refer to this web site for more testimonies of the on going problem with the steering system of the Acura ILX cars, specially my Acura the ILX 2020 model. https://acurazine.com/forums/ilx-382/ilx-suspension-noise-869859/

The factory original windshield wipers caused micro scratches in the glass. Dirt cannot be thoroughly cleaned from the scratches and collects more dirt during driving. When facing the sun, dirt particles in the scratches reflect in the scratches obstructing clear vision. Changing windshield wipers after just two years of use from new did not correct the problem. This particular vehicle is garaged.

Service News - Due to On-Board Diagnostic (OBD) regulation change starting with 2019 vehicles, American Honda’s Variable Valve Timing and Lift Electronic Control (VTEC) On-Board Diagnostic monitors are now included in the EGR/VVT OBD Monitor Readiness status group. Due to some customer’s driving patterns, they may not drive in the fashion needed to operate the VTEC (EGR/VVT) that only operates above 5,350 rpm to run the OBD monitoring. Therefore, the EGR/VVT OBD monitor group readiness status is not set to “Complete” when the customer presents their vehicle to a Smog Check station for inspection.

Service Bulletin - Vehicle owner notices condensation or moisture trapped inside one or both headlight assemblies that does not evaporate from the lamp due to the headlight making contact with a body panel creating a separation in the adhesive between the headlight lens and the housing, allowing moisture to enter the headlight.
