2017 Acura RDX electrical problems

Filed Aug 6, 2026 · Electrical · MD

I have been experiencing issues with the alarm system when I lock the car the alarm randomly goes off. I have had my battery replaced and it still happens. There is nothing touching the handles during these times, it happens randomly, something internal going on. The only way to be sure it won’t disturb my neighbors is to leave my door unlocked which is unsafe.

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. Occurrences are getting more frequent (almost every other day) and it just happened again today 3/3/26.

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.

I have a 2017 Acura rdx all wash lights on ( Check emissions, abs, brake, brake system, power steering, tpms, and hill start assist, air bags, no seatbelt). Been to 3 different dealerships nobody can figure out what's wrong because the car does not communicate with itself anymore. Unsafe to drive because some is majorly wrong. Losses acceleration and beeps at you that the whole vehicle is not working.

Keyless access unit and security system. Random ignition flickering and alarm going on and off numerous times with or without key nearby. Said to be commonly known issue for similar years for various Acura models including RDX.

Keyless Access Control Unit (a.k.a. Smart Power Control Unit) is defective. This is an electronic part and should not have failed. It causes random security alarm triggers, random flashing of exterior lights, clicking noises, and flashing of dash lights. There are plenty of discussion boards about this online with many complaints. A recall should definitely be issued.

Vehicle began jerking while in motion, and all error messages the vehicle has ability to display rotated across the screen, including PO848. Transmission was replaced by a dealer. Vehicle would not start two weeks later. Vehicle towed to dealer. Dealer stated battery and starter were bad. Both of those components replaced by Acura dealer. Within one week, alarm was sounding randomly and clicking noise coming from dash. Dealer is now replacing a control module. This is a safety issue because as it was jerking, I lost control of the vehicle. The car alarm going off for a prolonged time at high decibels puts the hearing of bystanders at risk. Seems the car poses a fire risk as well.
