2016 Acura Rdx

On May 25, 2026, while driving my 2016 Acura RDX AWD on the interstate at highway speed, it suddenly began running rough and felt as if I was driving over low, spaced-out speed bumps. The check engine light started flashing, and multiple safety-system warnings appeared, including AWD System Problem, Vehicle Stability Assist (VSA) Problem, Hill Start Assist Problem, Electric Power Steering (EPS) Problem, and lane-keeping warnings. The vehicle lost normal performance, and I was concerned about safely continuing in interstate traffic. The interstate shoulder was narrow, and the shoulder was ending where traffic was merging onto another busy interstate. I pulled over as soon as I could safely do so. The vehicle was then towed to the dealership for diagnosis. The Acura dealership diagnosed internal engine damage, cylinder misfires, and broken piston rings and advised that the engine required replacement. The vehicle had approximately 170,526 miles at the time of failure. Prior to this incident, the vehicle was operating normally, had been regularly maintained, and had not been involved in any collision. There was no indication that an engine failure was imminent. After researching the issue, I learned that Acura and Honda have issued technical service bulletins and warranty extensions involving certain J35 V6 engines equipped with Variable Cylinder Management (VCM), addressing conditions including excessive oil consumption, piston ring problems, spark plug fouling, and cylinder misfires. I am submitting this complaint because a sudden engine failure while operating at highway speed presents a potential safety risk. The failure also caused multiple vehicle systems and warning messages to activate simultaneously. The vehicle is currently available for inspection.

On several occasions, the car alarm starts randomly sounding. When my son went to the vehicle, the lights on the dash board were flashing on and off and there was a clicking sound. We replaced the batteries in the key fobs. The battery was low so we had that recharged but the problem continued. We replaced the car battery and that appeared to solve the problem for about 6 months. The same problem occurred again. The only way to stop the alarm from going off is to disconnect the battery. Leaving the door unlocked does not stop this from happening. When we searched online, it is clear this is a common problem with this car, but there have been no recalls or TSB issued. This is a safety issue because we need to disconnect the battery and leave the car unlocked when we leave the vehicle. This has not been inspected by any service center. Based on our research, Acura will recommend replacing the smart power control unit at a cost of up to $1500 or more. We are hoping that others have reported this as well.

The driver side airbag. And yes, it can be inspected. I was involved in a low impact accident, where I struck a minor curb. The airbag deployed in my face, causing a loss of consciousness and ongoing concussion. No warning signs at all. Not yet, the vehicle is being looked at on Monday. The vehicle was inspected by the police.

Please see attached photos regarding unsafe issue with our Britax 1 for life clicktight carseat purchased 2021 and utilized from the end of 2021 to Dec. 2024. The harness strap would not tighten with ease, so I tugged with light force and the bolts that held the button to loosen the harness popped out. The harness then would not tighten at all. We threw the seat away but wanted to report the issue to you out of concern for others who are still utilizing this seat.

While driving in the left of I20 East's two lanes on a descending hill with 5 cars ahead and an unknown number of cars behind at 70+ mph and all cars packed in close to the car ahead, I saw the lane had no real shoulder before a drop-off and the right lane had a narrow shoulder before it dropped off into woods and brush. The right lane was packed with 18-wheelers. In order to avoid constantly breaking the full length of the hill, I shifted into manual mode and a lower gear, but the car ahead began to brake suddenly and hard. Just a second before that car broke, I unlocked the shifter and was moving it forward to Drive. As the car ahead was drastically slowing, I had to hit the brakes hard to avoid rear-ending him, and the momentum of sudden braking threw my hand and the shifter all the way forward into Park. The transmission immediately produced a harsh grinding sound, I no longer could disengage the transmission from Park, and the only controls I now had were brakes and steering. Alarmed I knew I had to get to the right shoulder but I couldn't look back to see how close trucks were behind the one to my immediate right, but by braking that truck slowly moved ahead of me, providing a brief opening behind him in the right lane. As I cautiously moved into that opening, I could see an 18 wheeler approaching but still a short distance back. I continued slowly drifting into the right lane with blinkers on, when suddenly the approaching truck behind veered partially into the right shoulder in anticipation of passing me in the narrow shoulder lane. In the split second of his veering, I slowly continued into the shoulder lane causing him to veer back into the right lane, his rig full of new cars jerking back left. As I gradually slowed to a stop, the truck was approaching so fast that in my rearview mirror it looked like he might not miss me. As he shot by, he cleared me by not much more than a foot, his draft shaking my car. AN AUTOMATIC TRANSMISSION GOING INTO PARK @ 70MPH
