Acura
Rdx

The engine upper magnesium intake manifold is spider cracked around several mating half bolts causing an engine emission warning light to illuminate for bank #2 lean code. I believe the part number for the upper intake manifold is P/N 17160-5G0-A00. 2017 Acura RDX with 84,000 miles. The Acura mechanic knew what the issue was right away stating that it’s known problem with the magnesium intake manifold, but Acura doesn’t have a recall.

Acura RDX alarm keeps going off; smart power control unit (keyless access/tpms) is faulty.

Locked Acura RDX alarm goes off randomly for no reason. When the alarm is turned off all the lights on the dash are flashing on and off and ticking. The most recent is 8/14/25. But has happened on several occasions especially if locked with the key fob or the lock on exterior of door. On 8/14/2025 it was lock by the inside door lock.

Pearl white paint peeling on trunk of car, same issue as with MDX models.

I was at a stop light, car was stopped, the electronics on the vehicle looked like it went through a reboot, A/C blower fluctuated (turned off then back on), all displays went out and restarted like it does when you start the car. When the traffic light turned green, and I stepped on the gas, the car shuddered and hesitated, like the transmission, ABS and traction control were all going haywire. Then the car drove fine. As long as I do not slow down too much or stop. Once I got home and had to back up into the garage, it went through that haywire cycle again. This was the 3rd time this has happened on this car. But after I shut off the engine, wait a little while and start it again, symptom seems to go away, until it decides to happen again. I have had this car since July of 2024, and since that time, I have had this happen to me 3 times and 2 times to my wife. I have read on the net and one of the possibilities talked about if the ABS control unit, where soldered wires seems to be melting off of the circuit boards and causing intermittent connection, therefore exhibiting erratic behavior. There are even services on eBay where you can send in your whole ABS unit and they will open them up, clean and re-solder the wires. This seems to be scary and concerning from a safety perspective. Please investigate the issue for us who are affected. It is not just my year model car, but it includes Honda branded and different Acura and Honda model cars too. Thank you.

My car alarm starting going off at random throughout the night, last night and day today. The car also started flickering all the dashboard lights while the car was turned off completely. This seems like it’s the keyless access unit. I don’t know how the battery is not dead yet but seems like it will be tomorrow. The car has not been diagnosed by a dealership or independent service center but I’m seeing many people say they’ve had this same issue happen to them with the same year, make and model. There was no warning lights or symptoms instead I was woke up in the middle of the night to my car alarm going off. After turning the alarm off it happened again after about 5 minutes. My neighbor was outside and told me that it had actually been going off all night. I am now the villain of the neighborhood. This will definitely kill my battery as I’m watching and hearing electrical components turning on when I haven’t touched the key fob or door.

The RDX has been experiencing stalls when trying to accelerate, shaking/vibrations when accelerating uphill or around curves in roads. I received a letter about the Torque Converter having its warrantee extended. The letter stated if you are experiences issues related to the torque converter to contact the dealership. I took my RDX to the Acura dealership in which they stated the car did not show the code to have the Torque Converter replaced but instead I needed a transmission flush. I have stated that I am experiencing problems related to the Torque Converter and after replacing it a transmission flush is part of the process. The dealership is refusing to replace the torque converter but charging me $500 for a transmission flush.
