On the 2023 Acura RDX, honda recalled certain 2023 Acura RDX vehicles (alongside 2023 Civic, 2023 Integra and 2022 Accord) because a ball valve inside the Vehicle Stability Assist (VSA) modulator can leak brake fluid internally. Two consequences are documented in the campaign: the vehicle can move unintentionally while the electronic brake hold feature is engaged — the car creeps or rolls when the driver believes it is being held — and the driver can experience an unexpected increase in brake pedal travel, a long or sinking pedal that lengthens stopping distance. Owner notification went out in July 2023.

Common Symptoms

  • Vehicle creeps or rolls while brake hold is engaged
  • Brake pedal travels farther than normal or sinks
  • Brake warning light
  • Brake fluid level dropping without visible external leak

How to Fix

Free recall repair under NHTSA campaign 23V430 — the dealer replaces the VSA modulator assembly at no charge. Honda's internal recall codes for this campaign include OEJ, XEK, AEY, XEX and OEW. Verify the VIN at nhtsa.gov/recalls, since coverage is by production range and not all 2023 RDXs are included. Until repaired, do not rely on the brake hold feature to keep the vehicle stationary on a grade, and report any change in pedal feel immediately.

On the 2019-2023 Acura RDX, third-generation RDX owners report a loud high-pitched squeal when the brakes are lightly applied at 15 mph or below — pulling into a parking space, creeping in traffic. The noise is strongly temperature-dependent: it appears in ambient temperatures under roughly 50°F and the front brakes typically go quiet once warmed up, which is why dealers who test-drive a hot car often cannot reproduce it. Acura acknowledged it in service bulletin 19-053 (Front and/or Rear Brakes Squeal When Applied at Low Speeds) covering 2019-2020 cars, and revised the bulletin repeatedly as the condition persisted into later model years, with a later revision extending it to 2022 and the bulletin still listed for 2023.

Common Symptoms

  • High-pitched squeal when braking lightly under 15 mph
  • Noise only in cold weather (under about 50°F)
  • Front squeal disappears once the brakes warm up
  • No pedal pulsation or loss of braking performance

How to Fix

Under TSB 19-053 the dealer replaces the front and/or rear brake pads and discs with the revised parts — this is a materials/manufacturing issue, so the repair should be performed under the new-vehicle warranty at no cost, not sold as a maintenance brake job. Bring the car in cold and, if possible, with a recording of the noise, since the squeal often will not reproduce on a warm test drive. Check for the latest revision of the bulletin, as coverage was extended beyond the original model years. This is a noise-only condition — braking performance is not impaired.

Typical repair cost:$0 - $900

On the 2019-2023 Acura RDX 2.0L K20C6 Turbo I4, the True Touchpad Interface infotainment system in the third-gen RDX suffers from random reboots, input lag, and touchpad calibration drift. The system frequently loses its cursor position, making menu navigation frustrating and occasionally dangerous when the driver attempts adjustments while driving.

This issue also affects: Acura TLX, Acura ILX

Common Symptoms

  • Touchpad cursor drifts or jumps
  • Screen goes black and reboots
  • Audio cuts out for 30+ seconds
  • CarPlay disconnects randomly
  • System extremely slow after cold start

How to Fix

Update to the latest infotainment firmware which improves touchpad responsiveness and reduces reboot frequency. Recalibrate the touchpad through the system settings menu. If reboots persist, the infotainment control unit may require replacement under Acura warranty extension.

Owner tips & cautions

  • TipDisable the touchpad haptic feedback in settings — it reduces input lag noticeably. Also, the 2022+ firmware update is a significant improvement; insist on the latest version at the dealer.

On the 2019-2025 Acura RDX, the 2.0L K20C4 turbo in the 3rd-gen RDX is documented to suffer oil DILUTION rather than consumption — unburned fuel from direct injection washes past the rings during cold-start cycles (especially short trips in cold climates) and accumulates in the crankcase. Owners typically see the oil level RISE above the full mark, with a strong gasoline smell on the dipstick. Long-term, the diluted oil loses film strength and accelerates bearing/cam wear. Acura issued software calibration updates under TSB 22-039 to reduce cold-start enrichment time.

Common Symptoms

  • Oil level drops between changes
  • Low oil warning light at 5,000-mile intervals
  • No visible external oil leaks
  • Faint blue haze from exhaust on hard acceleration
  • Oil change required before maintenance minder reaches 15%

How to Fix

Monitor oil level monthly with the dipstick and top off as needed between changes. Use only 0W-20 full synthetic oil meeting Honda HTO-06 specification. If consumption exceeds 1 quart per 2,000 miles, request an oil consumption test at the dealer. Acura may replace piston rings under warranty if consumption is documented as excessive.

Owner tips & cautions

  • TipKeep a quart of 0W-20 in the cargo area. Check the dipstick every 1,000 miles and document each top-off with date and mileage. This paper trail is essential if you need to file a warranty claim for excessive consumption.
Typical repair cost:$50 - $3,000

On the 2019-2025 Acura RDX 2.0L K20C6 Turbo I4, the 10-speed automatic in the third-gen RDX exhibits harsh shifts during 1-2 and 2-3 upshifts, particularly when the transmission is cold. Owners also report a noticeable hesitation when accelerating from a complete stop, with a 1-2 second delay before the transmission engages that feels like the vehicle is going to stall.

This issue also affects: Acura MDX, Acura TLX, Honda Accord

Common Symptoms

  • Harsh 1-2 upshift when cold
  • Hesitation accelerating from stop
  • Jerky low-speed maneuvers in parking lots
  • Transmission clunk when shifting to Reverse
  • Rough downshift during deceleration

How to Fix

Update the TCM calibration to the latest Acura software revision, which improves cold-shift quality and reduces the hesitation from stop. Perform a transmission fluid change with Honda Type 3.0 fluid. Allow the adaptive learning to recalibrate for 500 miles after the update.

Owner tips & cautions

  • TipLet the RDX warm up for 30-60 seconds before driving in winter. The 10-speed is noticeably smoother once the ATF reaches operating temperature. The 2023+ calibration also significantly improved the stop-start hesitation.
