2019 ILX · 26,000 miles · Apr 2024

Possibility of incorrect vin number. I first noticed this issue when I tried to schedule an appointment with an Acura dealership. I was asked to enter my Vin number for my vehicle and when I did so it showed a different higher level trim than what I have. After conducting some research and purchasing couple of reputable detailed VIN reports using the Vin number on my car I saw that the vin on my vehicle does not match the trim level of the vehicle I am driving. The vin number appears to match a 2018 Acura ILX with a technology package. I do not have a technology package. My car has a premium package. I have reported the issue to my state attorney general office. Given this issue, I am unsure of whether or not there are any open recalls on the actual vehicle I'm driving because I am unsure if the Vin number is correct. …

2018 ILX · May 2024

The vehicle began experiencing a steering and suspension malfunction that made the car difficult to control, particularly at low speeds and when turning. There was increased vibration, unusual noise from the front end, and a noticeable pull to one side. These symptoms created a safety risk because loss of steering stability could have led to a crash, especially in traffic or on highways. The vehicle was taken to a Honda dealership for diagnosis. The dealership did not inform me of an active Acura safety recall related to the issue and stated that they "do not check Acura recalls." Based on their assessment, I proceeded with repairs at my own expense. I paid approximately $435 for the replacement part purchased from an Acura dealership and about $300 in labor to an independent repair shop. …

2016 ILX · 95,000 miles · May 2026 · crash · 1 injury

I own a 2016 Acura ILX and recently discovered multiple federally mandated safety recalls affecting my vehicle, including a brake master cylinder recall, fuel pump recall, driveshaft separation recall, and Takata airbag recall. I have owned this vehicle for over seven years and was never notified by mail or otherwise at my correct address that these safety recalls existed. One recall is currently active, but the dealership advised they cannot perform the repair due to parts unavailability until March, leaving me to operate a vehicle with a known brake-related safety defect. The remaining recalls are listed as not active, yet were never completed, and the dealer refused to perform them. I am concerned that required safety defects were not properly communicated or remedied, placing me and others at risk.

2016 ILX · Feb 2026

While driving downhill and using regenerative braking, my 2013 Acura ILX Hybrid suddenly experienced a hybrid system malfunction. Immediately after the event, the vehicle displayed "Check IMA System" and "Check Charging System" warnings and began exhibiting drivability and electrical-system problems. Following the failure, the vehicle experienced reduced acceleration from a stop, rough engine restarts, loss of auto-stop functionality, charging-system issues, intermittent low-voltage behavior, and eventual no-start/jump-start conditions. The vehicle was inspected and diagnosed by an authorized Acura dealership. Diagnostic testing identified fault codes P0A78 (Motor Power Inverter Internal Circuit Malfunction), P1440 (Motor Power Inverter Module Output Circuit Malfunction), and P1437 (Motor Power Inverter Module Short Circuit). …

2013 ILX · May 2026

Upon filling my 2013 Acura ILX, I would get back into the car and the cabin smelled like I spilled gas in the back seat. This happened on multiple occasions and there was a gray streak from the fender about 3 inches wide to it tapering to about an inch when it ended at the bottom of the fender/bumper area. I took my car to the dealership three times and the car was never tested under the conditions of when I had the issues. They did all the other tests except the one that caused the problem, the very bad gas fume smells in the cabin of the car. If I lit a match, that car would have blown up, easily, that's how bad the problem is with this car. The 2013 Acura ILX is the sister vehicle of Honda civic. The Honda civic was recalled for the model years 2011 and 2012 for fuel system issues which mimicked what I went through with this 2013 Acura ILX. …
