2023 Acura RDX Problems

This is a follow-up to my earlier complaint about the same vehicle, a 2023 Acura RDX A-Spec Advance. In August 2026 the vehicle was stolen from a public street after offenders broke through the exterior driver’s door handle, reached the wiring behind it, and lowered the window to get inside. On Oct 15th, offenders attacked the same driver’s door handle on the same vehicle in what appears to be a second attempt using the same method. The handle was broken, but because we spent a lot of money installing more security, the vehicle was not taken. Two attacks on one vehicle in about two months, both starting at the exterior handle, suggest the method is known and repeatable. We have heard this exactly from police and repair shops too. The door’s window and lock circuitry appears to respond to input at the handle area without authentication, so physical access to that point is enough to defeat the locking system and lower all windows. I am a repeat RDX owner (2008, 2017, and 2023 models) and did not experience this on earlier generations. I ask NHTSA to investigate whether the third-generation door and window architecture is vulnerable, whether other Acura and Honda models share it, and whether a remedy, such as requiring key authentication before the window circuit responds, is warranted. Police reports were filed for both incidents, and I can provide the damaged handle for inspection.

On September 3, 2026 at approximately 1 AM, my 2023 Acura RDX A-Spec was stolen from my residence while both of my authorized keys were in my possession. The exterior driver-door key cylinder showed evidence of forced manipulation/damage. Despite the vehicle being locked, the factory theft-deterrent alarm did not activate and I did not receive an AcuraLink theft/alarm notification. The vehicle was successfully entered, started, and driven away without an authorized key in the thief’s possession. After the vehicle was recovered, I contacted Acura Client Relations because I am concerned that the factory theft-deterrent/immobilizer system did not prevent the vehicle from being started and the alarm did not activate during the unauthorized entry. Acura has not identified the method by which the vehicle was started or provided an explanation for the reported non-activation of the alarm. I am reporting this because I am concerned there may be a vulnerability involving the door-lock, alarm, immobilizer, and other related electronic security systems that could allow unauthorized entry and theft. I am requesting that NHTSA evaluate whether similar incidents have been reported involving 2023 Acura RDX vehicles or other vehicles manufactured by American Honda Motor Co. including Honda and Acura vehicles.

The contact owns a 2023 Acura RDX. The contact stated that the vehicle was parked and retrieving an item from the front driver’s side door; after closing the door, the rear glass exploded without impact. The dealer was notified of the failure, and an appointment was scheduled. Upon investigation, the contact discovered an undisclosed Technical Service Bulletin that was associated with the failure. The manufacturer was notified of the failure, and the contact was informed that the model of vehicle was not included in a TSB for the failure. A case was filed with the manufacturer. The vehicle was not repaired. The failure mileage was 30,100.

The contact owns a 2023 Acura RDX. The contact stated that while driving in a heavy rain storm the windshield wipers was activated and suddenly seized. The contact was able to drive and park on the shoulder and the local police were contacted. After the rain storm passed the vehicle was safely driven home. The cause of the failure not determined. The manufacturer was not contacted. The failure mileage was 37,850.

On October 31, 2024, I was nearing the end of a three hour trip. I was traveling on a rural two-lane highway with a 55 mph speed limit. I had just pulled away from a 4-way stop intersection and was following a single vehicle traveling 40 mph. Once I could see there was a safe distance from oncoming traffic, I decided to pass the slower vehicle. As I moved into the opposite lane and accelerated, the engine lost power and barely made it around the car I was passing. If oncoming traffic had been closer there could have been a head-on collision. The engine light started flashing and I had to keep the accelerator pressed half way to the floor to maintain 50 mph. There was no shoulder on the road and no place to pull over, so I continued for 15 minutes with engine light blinking and struggling to maintain 50 mph. No other warning lights came on and the engine was not overheating. When I reached my destination I turned the engine off and then restarted it. The flashing engine light was gone and the car drove fine. The nearest Acura dealer was an hour away so I took the car to my dealer when I returned from my trip. They test drove the vehicle and called the Acura Tech Line. They could not duplicate the problem. They said they did not find any diagnostic codes so there was nothing they could do. They said if it happens again to bring it back. If it happens again I might not live to tell the story!

Highlight: The car was able to be started with a button press and driven away without any key inside the car. (Also, some side information that the car had it's annual check-up on the Saturday before this incident). Normally my wife keeps her purse in the house on the counter (along with the spare key in a drawer under that counter). Previously, if she forgot her purse (and car keys inside the purse), she would head out to the garage and attempt to start the car (she keeps it unlocked in the garage). In a normal situation, the car would beep at her that she didn't have the key and she would go into the house to grab her purse. On 7/31, after a frazzling day, she got a call from her doctor to come to their office for a checkup (40 minutes away). She forgot her purse again; however, this time, the car started without any warning. She took the complete drive to the doctor's office shut off the car and then realized she didn't have her purse. She even tried to turn the car back on to see if the key was in the car, it did not start. She called me, I checked her purse and spare key were both in the same location they were always in. I did remotely try to start the car to see if she could drive it back with me starting it, however, it wouldn't let her take it out of park. She continued with her doctor's appointment. Inconveniently, I grabbed her purse and took my car 40 minutes to drop off her keys and back. Luckily, she was at a doctor's office and in a safe space, however, this has the potential to be very inconvenient and unsafe for others.

My issue is with the liftgate on all Acura models including my own RDX. I was sitting on the edge of the van with the liftgate fully opened taking off my spikes after golfing. I inadvertantly triggered the fob in my pocket when i leaned forward causing the liftgate to close. At first i did not realize it was closing on me ,but jumped up and it caught me on my upper back. I avoided serious injury. Brought it to the dealership and it appears to be common to all makes of acura with liftgates. Serious pressure has to be put on the liftgate in order for it to stop . Page 177 of my manual states the if the liftgate detects resistance it will reverse itself. We tested it at the dealership and a great amount of pressure has to be used for it to stop and reverse. This is a serious defect and needs correction before someone gets seriously injured. The service advisor almost hurt her arm trying to get the liftgate to stop . It is not only my vehicle. the sensors do not react appropriately. I have had two Nissan Murano's before purchasing this vehicle and as soon as you got in the way of the liftgate as it closed it stopped and reversed itself. Acura has a serious problem here and it needs to be recalled and corrected immediately. I am totally surprised if this has not been brought to anyone's attention. Hopefully you will test this and see what I am expressing here. Thank you for you time and and I await your response .

Transfer case is defective and Acura is refusing to fix it under warranty. Says it’s’normal’ for the AWD system to leak causing destruction.

On a new ACURA RDX with 10,771 miles my wife was charged $315 dollars by the local ACURA dealer for "differential service" because "sub code 6" was on the maintenance minder. I believe this is a scam or any differential service should be under warranty. I pursued the complaint with HONDA extensively on the phone and just now was called back by HONDA and told that is regular maintenance and is not covered by the new car warranty. No car that I have ever owned needed differential service after 5 months - this is a scam.

The contact owns a 2023 Acura RDX. The contact stated that while driving at approximately 35 MPH, the Forward Collision Avoidance: Emergency Automatic Braking inadvertently activated, and the vehicle stopped. The contact was able to regain control of the vehicle, veer to the shoulder, and contacted the dealer to have the feature deactivated. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 7,888.

The contact owns a 2023 Acura RDX. The contact stated while driving approximately 70 MPH and overtaking another vehicle, the contact moved to the right lane and the vehicle started beeping with the Forward Collision Assist system engaging abruptly. The contact stated that the brake was applied independently without warning. The driver was able to avoid a collision. There were no warning lights illuminated. There were no other objects or vehicles nearby. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 2,000.

The brakes squeaks all the time and makes a grinding noise. I have been at the dealership several times for the same issue. The sensor also hit brakes on its own sometimes when nothing is in front of the car!!! Very dangerous!!!!
