Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes 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.

For the rear brakes, there is not enough dampening between the rear brake pads and shims.

The failure pattern owners describe
The 2019 RDX has four distinct brake problems documented in owner complaints. The most alarming is an interaction between Brake Hold and auto start-stop: when the engine automatically restarts (usually because the AC kicks in), the automatic brake hold releases and the car creeps forward while stopped. This has happened repeatedly at traffic lights and in traffic without driver input—a hazard if a pedestrian is crossing or another vehicle is nearby.
Brake squealing or squeaking is widespread and chronic. Owners report persistent noise from day one, at all temperatures, whether braking hard or light. Acura dealerships acknowledge it as a known issue affecting 2019 RDXs but say they cannot fix it without an official repair. Some owners had pads replaced three or more times with no improvement. One dealer offered a $300 Visa card as compensation but no lasting fix.
A smaller number of owners experienced soft or unresponsive brake pedals requiring excessive pedal travel to stop the car. Acura addressed this with reprogramming (Honda TSB 19-022), though one owner was charged $87.78 and Honda denied reimbursement. One complaint detailed a brake pedal failure combined with instrument panel malfunction and rapid battery drain, with dealer repair attempted but unsuccessful.

Failure modes owners describe
Brake Hold / Auto Start-Stop Interaction
When Brake Hold is engaged and the engine auto-shuts off at a stop, the auto start-stop system sometimes re-starts the engine (typically due to HVAC demand). Upon engine restart, the automatic brake hold releases unexpectedly, causing the vehicle to creep or roll forward while the driver is stationary. This has occurred repeatedly in traffic and at traffic lights.
When: During traffic stops with Brake Hold and auto start-stop both enabled
Symptoms owners cite: Vehicle moves forward without driver input while stopped at traffic light; Brake hold releases when engine auto-restarts; Engine restarts due to HVAC system activation while at stop; Vehicle creeps forward in traffic
Recalls/TSBs owners mention: No recall mentioned by owners; issue documented on Acurazine forum
Intermittent Brake Squealing (Front Brakes)
Brakes produce persistent loud squealing or squeaking noise during braking, present from delivery on many units. The noise occurs at all outside temperatures and all braking speeds. Some owners report pad replacement at dealer (multiple times on same vehicle) with no resolution. Acura acknowledges this as a known issue on 2019 RDX models but has not issued a fix or recall.
When: Since vehicle delivery; continuous occurrence
Symptoms owners cite: Loud squealing from front brakes during stop; Squeaking noise every time brake pedal is applied; Squealing at all outside temperatures; Shaking sensation with squeaking brakes
Repairs/costs cited: Brake pads replaced multiple times (3+ times on some vehicles) by dealer with no resolution
Recalls/TSBs owners mention: Acura acknowledges as known issue on 2019 RDX but states no fix available; one dealer offered $300 Visa card compensation for inconvenience
Soft / Non-Responsive Brake Pedal
Brake pedal feels soft and does not stop the vehicle until pedal is pressed nearly to the floor. Requires excessive pedal travel for normal braking. Owner reports Acura dealership referenced Honda TSB 19-022 as the remedy. Vehicle required reprogramming to correct the issue.
When: Occurred on 2019 model; complaint filed at approximately time of purchase experience
Symptoms owners cite: Brake pedal feels soft; Excessive pedal travel required to stop vehicle; Pedal must be pressed nearly to floor to achieve braking
Codes mentioned: Honda TSB 19-022
Repairs/costs cited: Vehicle reprogramming performed; dealer charged $87.78 for reprogramming service
Recalls/TSBs owners mention: Honda TSB 19-022 available; Honda classified as maintenance issue and denied owner reimbursement request (case 12954925)
Brake Pedal Failure with Instrument Panel Display Issue
Brake pedal failed to operate while coming to a stop, with no warning light illuminated. Instrument panel display failed to display properly and caused rapid battery drain. Dealer replaced unknown wiring but the failure persisted. Exact root cause not disclosed in repair documentation.
When: Approximately 49,000 miles
Symptoms owners cite: Brake pedal failed to operate during stop; Instrument panel display failure; Rapid battery drain; No warning light illumination
Repairs/costs cited: Unknown wiring replaced; vehicle repaired but failure persisted
Recalls/TSBs owners mention: Manufacturer notified of failure
