2017 ACURA RDX Electrical System Problems

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

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.

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.

The alarm and lights keep going off for No reason. The doors can be locked and Armed. Goes off even when not 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.

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.

Part - Control Unit, Smart Power - Acura 38320-TX4-A31 has been diagnosed as defective causing major electrical issues. Dealer says it affects the safety features of the car yet they can't get a replacment part. Afraid to allow my wife to drive not knowing if the safety features we paid for actually work. Air bags? Electrical breakdown during operation? A simple search finds it is a common problem with Acura and Hondas of this time period.

Since we have had the car we have had multiple issues with the car jerking and shifting hard after driving in S mode then going to standard mode. Dealership told us the transmission is "sensitive" in our model year and if we go 1 mile overdue for a transmission fluid flush we will have shudder/jerking/ hard shifting. (we have changed the transmission fluid 1-2x since have had the car, which is within range of recommended). Last episode- battery was dead, jumpstarted and car jerking at low speeds to the point I did not drive it and had it told. We were also told their was a short in the circuit board that controlled acuralink and what charged the battery. Jerking transmission related per dealership. lastly the sound for the blind spot monitoring is intermittently not working.

Keyless entry system failed at under 50k miles. When this Keyless Access Unit fails, you cannot start the car and the powertrain. The only way to resolve is to have the car towed to the dealership and have the part orders and installed at over $800. In a worst case scenario, the driver could be stranded in unsafe conditions -- weather extremes (heat or cold) or parking at the side of the freeway unable to restart the car. I believe this is a huge safety issue and too common for this model Acura. This is clearly a critical system component that has failed far before it should. There is no way to turn the vehicle on as this is a keyless entry vehicle.

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.
