I am leasing a 2025 Acura MDX with approximately 16,000 miles, acquired new in June 2025. The A/C system has failed and only blows hot air. The vehicle is available for inspection. I first noticed reduced cooling Thursday evening, August 20, 2026. By Friday, August 21, when it was approximately 89°F, the A/C was no longer producing cold air. I restarted the vehicle twice and repeatedly turned the climate controls and A/C on and off, but only hot air came from the vents. No warning lights or messages appeared. I contacted Cerritos Acura on Friday and spoke with the Service Director. I explained the failure, but the earliest appointment offered was approximately a week and a half later. I asked if they could arrange service elsewhere or contact another Acura dealer for an earlier appointment, but both requests were declined. On Monday, August 24, I had to commute approximately two hours to work without A/C during heat advisory conditions. I became extremely overheated and was concerned I was approaching a heat-related medical emergency. I consider this a serious safety concern, especially for a nearly new vehicle. The problem has not yet been diagnosed because the dealer has not inspected the vehicle.

The contact owns a 2022 Acura MDX. The contact stated that drops of fluid were discovered on the floor of the garage. The contact stated that while driving at an undisclosed speed, the vehicle failed to properly accelerate while depressing the accelerator pedal. The vehicle was taken to the local dealer for diagnosis, and the contact was informed that transmission fluid was leaking due to a failure of the Power Take Off (PTO) unit and transmission spline, causing the transmission to overheat and leak fluid. The contact was informed that the transmission and PTO unit needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was 97,000.

My 2016 Acura MDX (purchased new January 2016) has a confirmed failure of the 9-speed automatic transmission warmer (ATF warmer), causing engine coolant and ATF fluid to cross-contaminate. The failed warmer is still in the vehicle and available for inspection. In the last week of March 2026, I noticed the engine cooling fan continuing to run after shutting off the vehicle — an abnormal symptom that prompted me to bring the car in for service. No check engine or transmission warning lights were illuminated. On March 28, 2026, Blue Sky Tire and Auto (Cumming, GA) performed a diagnostic inspection confirming coolant and ATF cross-contamination. The technician also physically inspected the transmission warmer manufacturing date stamp, confirming it falls within the defective manufacturing date range identified in Acura Service Bulletin 17-009 (October 6, 2017), which states that improperly manufactured warmers allow coolant and ATF to mix, potentially causing permanent engine and transmission damage. The vehicle has not been inspected by an Acura dealership for this failure. However, an American Honda Customer Relations case has been opened (Case # XXX) with a case manager assigned to evaluate the warranty claim under the 10-year/unlimited mileage warranty extension issued by American Honda for this exact defect. This failure poses serious safety risks — loss of transmission lubrication can cause sudden transmission failure at speed, and coolant-ATF mixing can cause engine overheating, both potentially resulting in loss of vehicle control.

Front windshield camera went bad due to overheating. When malfunction it gives multiple warning lights, everything that has to deal with front windshield camera does not work. Ive hearing multiple and multiple stories online and in person that they too is affected by camera malfunctioning. There needs to be a recall on it as it is affecting way too many people. My car is a 2019 with ONLY 47000 miles pretty much still new. Parts plus labor and camera calibration is $2200

### 1. **What component or system failed or malfunctioned, and is it available for inspection upon request?** The rearview camera system in my 2020 Acura MDX has malfunctioned. The camera, which is integral to several safety systems in the vehicle, has failed, causing significant safety concerns. The vehicle is available for inspection by an Acura dealership or independent service center upon request. ### 2. **How was your safety or the safety of others put at risk?** The malfunction of the rearview camera directly impacts the **Collision Mitigation Braking System (CMBS)**, **Adaptive Cruise Control (ACC)**, and **Lane Departure Warning (LDW)** systems. These systems rely on cameras and sensors to detect obstacles, maintain a safe following distance, and alert the driver when switching lanes. Without the proper function of the rearview camera, these safety systems become unreliable, increasing the risk of head-on collisions, rear-end accidents, or unintended lane changes, which could lead to a serious crash. Furthermore, the area surrounding the malfunctioning camera becomes dangerously hot, posing a burn risk when touched, which adds another safety hazard. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes I have taken the vehicle to a dealership for a formal inspection, I have confirmed the issue through the consistent malfunctioning of the camera. The overheating and failure of the camera have been present since the issue began, and I have communicated this to Acura's customer service. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by the manufacturer beyond the initial communication with Acura’s customer service. No inspection has been conducted by the police or insurance representatives. However, I have made Acura aware of the problem, and the customer service team, led by Account Manager Monica

We were on a highway drive to a state park 45 minutes from our house on [XXX]. 40 Minutes into the drive the check engine light flashed. We had just taken a long road trip from Minnesota to Ohio (and back again) the week before (10/15-10/20) and had NO problems whatsoever. We parked and read what we could online as to what to do. Checked the gas cap tightness, the oil, etc. and let the engine cool for 2 hours. Started the car and no lights came on. So we started driving home. 35 Minutes later ALL the lights on the dash came on. Scrolling through every system in the car-transmission, brakes, lane assist, etc. We pulled Over almost immediately. Turned the car off checked under the hood but nothing seemed glaringly wrong. It wasn’t overheating or smoking or anything. We tried to drive it directly to our mechanic. Got back on the highway and the engine would not get up to speed, just groaning. Worried we would be in danger on the highway we pulled over and called for a tow. The first mechanic that reviewed (just local not Honda) could hear a knocking in the engine. Towed it to an Acura dealership on 10/28/2024. The Acura mechanic there confirmed that it is a rod/rod bearing issue—but we don’t fall under the recall. The rod came loose in the engine, banged around, damaging the engine. Cost to fix is $10,000. This information came to us on 11/4. We filed a complaint with the Acura/Honda recall department that day. We have been waiting to hear their verdict (after their investigation) for the last week. We have been told multiple times that our car doesn’t fall under the original recall. But the Acura mechanic has confirmed it is the same issue.

The engine consistently consumes too much oil between service events. The low oil light comes on. I had this problem for over 8 years and the dealership said it was not a problem until now and they want me to pay for it. The oil control rings have been clogged since 2016 and progressively gotten worse. The clogged rings cause restriction of oil to return to the crankcase. This causes a decrease in available oil and may cause overheating that could lead to engine fire. Acura should fix the oil control rings to function properly. They have identified this in the past, through a service bulletin (19-006). I have performed 97% of my oil changes at Acura dealerships.
