I can hear and feel the car struggle to move forward, about 2 minutes into the drive a hear a big TOON and check engine light is on for about a minute before going away. I filled gas and headed back home and I heard a larger TOON but this time all the warning light came up.

My 2017 Acura was involved in a low-speed collision where it failed to stop in a timely manner, resulting in a total loss declaration. This vehicle had open safety recalls (including the fuel pump/rod bearing issues) that remained unrepaired for over 1.5 years. Despite multiple inquiries, the manufacturer failed to provide a repair timeline or remedy. I believe these unresolved defects directly contributed to the braking failure and subsequent safety incident.

Adaptive Damper System error on dashboard. Took the car to the dealer and they confirmed two issues. Codes C1646-14 and C1647-14 indicating the stroke sensor has lower limit abnormality. Dealer recommended replacing both rear shocks due to over extension. Once shocks were replaced, codes returned. During further investigation, corrosion was found in the stroke sensor wiring harness. Harness is the root cause of the issue. Car is available at the dealer for inspection if necessary. From a safety perspective, if I continued to drive the car I could have experienced a malfunction in the braking system which could have led to brake failure, failure of safety features, or a car stall.

Warning lights for Electric Parking Brake Problem and Emissions System Problem simultaneously occurring with no definitive solution. Codes can be cleared by disconnecting battery and reconnecting but warning lights eventually come back on sometimes in a matter or days, weeks or month. There are no other issues that coincide with these warning lights coming on.

To Whom It May Concern: The purpose of my complaint is to bring to your attention reprehensible policies and misconduct displayed by the automaker, Acura, the premium subsidiary brand of the American Honda Motor Company. On 11/18/2025, I brought in my 2021 Acura TLX Tech w/SH-AWD in for a problem related to the brakes. The front brakes were and continue to make a jarring, very loud, high-pitched squeaking noise at low speeds. After 4 hours at Radley Acura of Falls Church, VA, the technician stated "could not duplicate" the concern. The problem persisted and I again returned on 12/18/2025 for the same issue. My vehicle has been at the dealership awaiting a response from Acura Client Relations on a claim that I submitted on 12/19/2025. Radley Acura diagnosed the issue as a well-known defect of 2021 TLX models, as evidenced by Acura's own service bulletin describing the very issue I continue to experience (and yet were unable to diagnose on 11/18). Radley Acura is stating that although my vehicle is 28,000+ miles UNDER the manufacturer's warranty, that by time, since purchase, it is outside the manufacturer's warranty by approximately 6 months. However, on 1/27/2025 (when my car was within manufacturer warranty and only had 17,215 miles on the odometer), I completed a lease buyout of my car. In addition, I paid to have it Acura Precision Certified. As part of this paid certification, Radley had my car for over a day to allegedly perform a 182-point inspection, and address a recall open for over a year (with a remedy from Acura - but allegedly no available repair parts to fix my car, until I requested to CPO my at the time of lease buyout). During their CPO inspection, the dealership failed to address the open service bulletin on the front brakes--a documented issue Acura has been aware of since before 2/15/2022, as established by their service bulletin. Now the dealership is stating the manufacturer's defect that they failed to address is $500 out of pocket expense.

SERVICE BRAKES
While braking and attempting a left turn at an intersection, my vehicle completely shut down with no braking or steering control. Fortunately there were no damages and the vehicle started up again and I was able to clear the intersection. I took the vehicle to an authorized dealer for repair. They indicated that this was a known issue and they were familiar with it. They installed a battery sensor and did brake work as they said there was air in the system. I paid for the repair and approximately a month later, while slowing down for a red signal, the same thing occurred, only this time my vehicle impacted another vehicle, causing damage to both vehicles. I had my vehicle towed to the shop that did the initial repair, but they said they could not find any codes that would indicate that their repairs were faulty.

Loss of brake power with “brake” light and “brake service” light on. I was backing out of my driveway and lost almost all braking power almost pushing the pedal to the floor. Once I came to a stop, I turned the car off and turned it back on, brake pedal felt fine and lights went away at that point.

SERVICE BRAKES
I had an awful noise that accompanied a sticky/ inconsistent brake pedal feel and braking concerns. Upon contacting multiple dealerships and honda corporate is was told everything is working as designed. I filed a claim with NCDS and was awarded a repair. When contacting the dealership and manufacturer they did another inspection and said it's working as designed and there was nothing to repair. Now in the news they are recalling approximately 250,000 Hondas/Acura vehicles for a safety issue with the brake pedal. There is no information on what the recall is supposed to entail. My vin is still not associated with the recall. This is a safety issue that the manufacturer has been ignoring for a long time now.

My husband and I have a 2022 Acura TLX (purchased new) that was issued a safety recall. We brought the car into the dealership in April to fix the problem. Two weeks later, the car completely malfunctioned- every warning light went off at the same time, and the car completely lost control. Steering, brakes, power/gas, everything went out. During this second visit, the dealership replaced the PCM. Last night, the exact same issue happened. My husband was thankfully near home, but if he was on a highway, he could've easily been killed. Again, everything in the car went out- steering, brakes, power- and he had zero control of the car. The car was towed a couple hours ago to the dealership (third time since initial visit in April), and the service manager said, "This has never happened before..." and had no answers. This is an extremely high risk situation, and we do not feel safe getting into this car when the dealership/manufacturer is clearly not able to fix their own safety recall.

The car is constantly throwing codes for faulty emissions system problem and parking brake problem but the car runs fine. The dealership will not do anything unless I pay them a fee to diagnose it and then they suggest replacing the catalytic converter even though it’s very likely a faulty fuel hose or faulty sensor. This needs to be recalled and fixed immediately
