Common problems reported by 2020 Acura Rdx owners, with recommended fixes and estimated repair costs.
Fuel Pump Failure (Recall)
The low-pressure fuel pump inside the fuel tank may fail, causing the engine to stall without warning while driving. This recall affects 2020-2022 Acura RDX models as part of a broad Honda/Acura recall campaign covering millions of vehicles.
Honda issued recall 23V-858 to replace the fuel pump module free of charge. Contact your Acura dealer with your VIN to verify eligibility and schedule the repair.
Est. Cost: Covered under recallHigh-Pitched Brake Squeal at Low Speed
A high-pitched squeal is heard from the front and/or rear brakes when lightly applied at speeds below 15 mph, such as during parking lot maneuvers or approaching a stop. The noise typically disappears once the brakes warm up after several applications.
Acura issued a TSB addressing brake noise on third-generation RDX models. The fix involves replacing the brake pads with an updated compound that reduces cold-weather squealing. In some cases, the rotors may need resurfacing to remove glazing.
Est. Cost: $200 - $600 per axleInfotainment Touchpad Glitches and Freezing
The True Touchpad interface infotainment system may become unresponsive, freeze during use, or register incorrect inputs. The system can take a long time to boot after starting the vehicle, and Apple CarPlay or Android Auto connections may drop frequently.
Acura released software updates to improve touchpad responsiveness and system stability. Visit the dealer for the latest infotainment firmware. Acura also offered an extended warranty on certain infotainment components. A hard reset (hold power button for 10 seconds) provides temporary relief.
Est. Cost: $0 for software update; $500 - $1,500 for unit replacementParking Sensor False Alerts in Rain
The front parking sensors embedded in the honeycomb grille pattern may produce false beeping alerts when driving slowly in rain, through puddles, or in car washes. Water droplets on the sensors trigger false proximity readings that annoy the driver.
There is no permanent fix from Acura at this time. Some owners disable the parking sensors temporarily via the dashboard button during rain. Keeping the sensor faces clean and free of debris can reduce false triggers. Aftermarket hydrophobic coatings on the sensor faces may help.
Est. Cost: $0 (work-around by disabling sensors)Check Engine Light with DTC P0087 (Fuel Rail Pressure Low)
The check engine light illuminates with DTC P0087 indicating fuel rail pressure is too low. The vehicle may experience reduced power, hesitation, or rough running. The issue can be related to the high-pressure fuel pump, fuel pressure regulator, or fuel filter.
Acura issued a TSB to diagnose and address fuel pressure concerns. The dealer will inspect the high-pressure fuel pump and fuel system components. The high-pressure fuel pump or its regulator may need replacement.
Est. Cost: $300 - $1,200
