2016 Acura RDX problems

“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.…”

“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.”

“Vehicle constantly surges during acceleration, seems as if the transmission is bad however, it also feels as if the fuel filter is clogged. This sputter occurs at various speed. Vehicle has less than 64,000 miles. Is there a fix to this issue?”

The contact stated that he depressed the brake pedal with force, however, the pedal did not respond and depressed to the floorboard with no resistance. The contact stated that he was pumping the brake pedal when he crashed into the deer. The contact stated that the vehicle continued forward for several hundred yards before he was able to stop the vehicle. The contact stated that he was able to drive the vehicle to a dealer, it was an out-of-state dealer since he had been traveling when he crashed into the deer.

The contact stated that the out-of-state dealer repaired the crash damage and replaced the brakes with new pads and rotors. The contact observed that the vehicle was having a failure of the tire pressure monitoring system light which was constantly illuminated, the windshield wiper motor was failing intermittently and the brakes continued to feel "mushy."

“From the time purchased there has been a hesitation/sputtering during acceleration. I took the car in during the warranty period and they said nothing could be found. It has continued for 6 years. I have read of similar problems with this model and year.”
