What stands out
Of the 12 model years of Acura RDX we track for electrical problems, this one carries the most owner complaints on file — 31.
Owners have filed 31 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Service Bulletin - A coaxial cable terminal was not manufactured to proper specifications. An improperly manufactured terminal may lead to poor communication in the media-oriented system (MOST) bus network which can potentially affect the audio sound quality.
full bulletin at NHTSA ↗Service Bulletin - The MIL is flashing with a loss of power. This is most common in hot, humid regions, or after a period of rainfall. Humid air within the intake passage may condense and accumulate moisture during steady driving which enters the engine and may cause a misfire and a flashing MIL.
full bulletin at NHTSA ↗Service Bulletin - The client may notice a loss of auto function, or no function, of the sunroof glass/sunshade due to a Motor-Control Unit error code in the clock frequency check falsely detecting a failure.

The failure pattern owners describe
Owners report three categories of serious issues: engine shutdowns, infotainment failures, and glass defects.
The most critical is fuel pump failure and sudden stalls. Multiple owners describe abrupt engine loss while driving at highway speed or merging into traffic—one owner stalled in below-freezing temperatures at night in a remote area with a minor in the car; another lost power on a busy interstate during rain. The vehicle goes completely dark with no electrical power, no power steering, and cannot shift to neutral for towing. Dealerships report no fuel pressure; some fuel pumps were replaced per recalls 21V-215 and 20V-314, yet failures recurred.
Acceleration loss is equally dangerous. Owners accelerating in rain or highway conditions report the engine entering limp mode, dropping from 70 mph to 35 mph. The check engine light flashes then disappears after restart, but no permanent fix emerges.
Infotainment failures plague these vehicles. Screens freeze with "Loading" messages, go completely blank, or disconnect Apple CarPlay mid-drive. Backup camera display fails, navigation stops working en route, and some screens stay on after the car is off, draining the battery. One owner noted Acura's dealership said to use YouTube videos to reboot instead of coming in for service. Acura admits the system doesn't work but offers no fix or timeline.
Rear windshields spontaneously shatter while parked—one owner had two replacements costing over $1,000. Acura's TSB 22-014 documents a rear defroster grid defect but no permanent remedy is offered.
Multiple owners report Acura acknowledging known issues but refusing to repair or replace vehicles.
