While driving in the rain, after an hour long drive home from Philadelphia back to Reading, taking [XXX] and [XXX], I accelerated my vehicle while going around 50 mph and immediately was faced with a blinking check engine light and lost the ability to accelerate. My Acura essentially went into, what others call, limp mode while in sport mode. I filled my car with 93 gas around 20 minutes before this. After losing acceleration, I pulled over on the highway and the check engine light disappeared. After which, I still was unable to accelerate after leaving the car in park. After I turned the car off and turned the car back on maybe 30 seconds later, I was then able to accelerate and found no issues afterwards.

On July 12, 2025 my husband, the driver, and myself, owner of the vehicle and passenger this day, were driving on the freeway at approximately 7:00am in the middle lanes of the freeway. Without any codes or warnings beforehand, we heard the car make alarming beeps and automatically loss all power to the engine while traveling at highway speeds. This situation put my husband and my lives at risk and in a dangerous situation as there was traffic on a busy freeway and lost all power to the vehicle and made even maneuvering off the freeway a dangerous action as we had no warning beforehand there was something wrong. My husband was able to get us safely out of harms way. After being diagnosed at a mechanic, it turns out this problem happened due to a cracked cylinder head and had no previous warnings of an issue and no warning lights on the vehicle alerting to a problem, I will have the cylinder head in my possession and the mechanic I took my vehicle stated it cannot be ruled out this could be a manufacturer’s or casting defect. I tried contacting Acura Corporation about this situation but was told that since I did not take it to a dealership and have a certified tech look at my vehicle, there will be no case and no type of remedy or reimbursement for this situation.

Purchased used 2019 RDX from Acura dealer in June 2025. Within the first 30 days of owning the RDX we noticed the Airbag Sensor for the front passenger seat would not recognize my 90 lb daughter seating in the seat and the air bag sensor would indicate the seat was empty, which would result in the airbag not deploying if we were in an accident. I took video of this happening and took my RDX into dealership for repair as we were still within the 30 day period for issues. The Acura dealership insisted they could not replicate the problem so it was fine. I again referred to the video and said we have seen proof of the issue. After much back and forth and the service manager telling me his large dog sometimes doesn't set off the sensor he agreed to call American Honda to send out an engineer to test. The engineer after running tests said seat is calibrated correctly no issue to fix, even if we wanted to pay to fix it ourselves they wouldn't fix the seat sensor because there is no issue to correct. I don't understand how a car that advertises a safety feature for anyone that weighs over 65lbs can expect me to continue to drive this vehicle when it has a proven faulty sensor. Obviously how they test the sensor is faulty as well. This is a huge safety issue for the 2019 RDX and a disappointing and shocking lack of response from Acura. We are now working to return the car to the dealership and I am sure we will have to fight to not pay extra costs that will occur with them buying it back.

I am writing to formally bring to your attention a recurring and concerning design issue with the Acura RDX involving the sunroof drainage system. This problem appears to stem from a flawed design in which the drainage channels frequently become clogged, leading to water accumulating and eventually leaking into the vehicle’s cabin and trunk areas. In my personal experience, this defect has resulted in persistent water intrusion that not only damages the interior but creates a serious risk for mold and mildew growth, along with unpleasant and unhealthy odors from sitting water. The accumulation of stagnant water inside a sealed vehicle presents a clear health and safety concern, particularly for families and daily commuters. The cost to have the drains professionally cleared at the dealership is approximately $300 per visit. I have been advised that this cleaning will be an ongoing necessity, despite the fact that this type of maintenance is not commonly expected of vehicle owners as part of standard upkeep. In comparison, this expense surpasses the cost of regular oil changes or tire rotations — yet it addresses a problem that stems from the car’s design rather than from use or neglect. I contacted both the dealership and Honda customer service and was told there is no permanent fix for this issue. The best they could offer was to cover 50% of the cost for a temporary solution — drain cleaning — which does nothing to resolve the root design flaw and will inevitably need to be repeated. As a consumer who has invested in a premium vehicle, I find this resolution to be unacceptable and financially burdensome. I respectfully request that the NHTSA investigate this matter as a potential defect affecting vehicle safety and integrity. Given the number of similar complaints circulating in consumer forums and online reviews, it is clear that this is not an isolated incident, but rather a systemic problem that deserves further attention and possible action.
