2017 Acura RDX Electrical System

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

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.

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.

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.

Dashboard warning lights all light up at once. Flickering on and off. Lights turn on and off inside car, it unlocks and locks car on it’s own. Says key is not close to car when trying to turn on car. Alarm goes off randomly once parked and locked.

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.

On Friday May 10, 2022, as I was merging from a local road to the highway, I tried to accelerate to complete a safe merge however, the car stated loosing power and jerking, I had to floor the accelerator to get the power needed to avoid a collision with the vehicle behind me. About 1 mile later, the care started loosing power again and cut out. I restarted and continued driving, a few yards later, the car jerked and all the warning lights came on. Given the serious safety issue and the fact that I happened to be near the an Acura dealership, I slowly drove to that dealership. Since it was close to the end of the business day on a Friday, I knew that I'd have to wait until the next day or week to get a report on the problem. I previously filed two complaints on June 19, 2019 and July 28, 2019, on this same issue. I spoke with a representative of Honda several times and they assured my that the problem was fixed after the dealer kept this car for several weeks to work on it. At this juncture, given that this is an issue that could cause serious harm, I am ready to sell this car. Honda needs to fix this.

THIS VECHICLE STARTS TO LOOSE POWER, JERKY ACCELERATION THEN CUTS OUT COMPLETELY. ALL THE LIGHTS COME ON INCLUDING CHECK ENGINE AND REMAINS ON UNTIL I TAK IT TO THE DEALER. PURCHASED IN MARCH 2018, THIS IS A CONTINUAL PROBLEM AND GETTING WORSE. THREE TIMES IN THE PAST MONTH. THE DEALER KEPT THE VEHICLE FOR THREE WEEKS FROM JUNE 20, 2019, AFTER THREE (3) WEEKS HE TOLD ME THERE WAS NOTHING WRONG. PROBLEM OCCURED AGAIN TODAY, JULY 28, 2019.

FOLLOW-UP TO COMPLAINT #11240187: ACURA WAS MADE AWARE TO THIS SITUATION THIS SITUATION WITH THE CAR LOOSING POWER AND CUTTING OUT IN THE MIDDLE OF TRAFFIC IS VERY DANGEROUS. I HAVE CALLED THE MANFACUTRER SEVERAL TIMES TO NO AVAIL. IN ADDITION I LOSE TIME FROM WORK EACH TIME I HAVE TO TAKE MY CAR IN. DATES OF INCIDENTS: JULY 28, 2019, JUNE 20, 2019, JULY 20, 2018, MARCH 4, 2018. PLEASE HELP I NO LONGER HAVE CONFIEDNCE IN THIS CAR. DANGEROUS!!
