What stands out
Of the 7 model years of Acura RDX we track for brakes problems, this one carries the most owner complaints on file — 20.
No new NHTSA brakes complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Used 2020 RDX buyers should know that brake noise—squealing, grinding, and scraping—is a documented problem that shows up early (under 2,500 miles) and often persists even after dealer replacements of pads and rotors; there is no confirmed permanent fix from Acura. Additionally, rare unintended brake activation incidents at highway speeds have been reported, though dealers claim they cannot replicate the failure.
Brake noise—squealing, grinding, and scraping—is the dominant complaint among 2020 RDX owners, appearing within the first 2,500 miles and often immediately after purchase. The noise typically occurs during normal braking at any speed, though it's most noticeable during light braking (15 mph or less) and worsens in wet or cold conditions. Multiple owners report the noise returning or persisting 500 miles or more after dealers replaced front and rear pads and rotors.
Acura has acknowledged this as a "known issue" affecting vehicles from certain production runs and mentioned a possible material defect or incorrect brake pad sizing. Dealers reference a service bulletin (MC-10168081-0002.PDF) and claim engineers are developing a fix, but owners report being told there is currently no solution. Acura has repeatedly stated the noise is not a safety concern, though owners express fear driving their vehicles.
Two separate incidents of unintended brake activation at speed—once near a railroad crossing at 45 mph and once on the highway at 70 mph—have also been reported. In one case the vehicle entered limp mode and did not respond to throttle. Dealers were unable to replicate either failure.
Cold-weather brake grabbing, where brakes squeal loudly and feel like they lock during cold months, appears to be a separate issue that warms out of the symptom but returns within 30 minutes of shutdown.

Failure modes owners describe
Brake noise—squealing, grinding, scraping
Recurring squealing, grinding, or scraping noises emanating from front and/or rear brakes during normal operation. Many owners report the noise persists or returns after dealer service replacements of pads and rotors. Some note the noise worsens in cold or wet conditions.
When: As early as 100 miles; most commonly 1,100–2,500 miles; can occur at any speed but often noticeable during light braking (15 mph or less) or after vehicle has been parked.
Symptoms owners cite: High-pitched squealing or squeaking when brakes applied; Grinding or scraping metal noise when braking; Abrasive rubbing sensation during braking; Vibrations when applying brakes (especially in wet conditions); Noise returns 30 minutes to 500 miles after repair
Repairs/costs cited: Dealers have replaced front and rear brake pads and rotors at mileages between 100–2,500 miles at no charge in most cases reported. Acura acknowledged it as a known production issue and mentioned a potential material defect or wrong brake pad size; some dealers opened tickets for brake pad remanufacturing. One owner reports brakes were the wrong size; another received a 2019 tech bulletin fix that was temporary.
Recalls/TSBs owners mention: Acura acknowledged the issue as 'a known issue' affecting vehicles from certain production batches. Dealers and corporate advised owners that engineers were working on a solution via service bulletin (referenced: MC-10168081-0002.PDF) but stated it is not a safety concern. Multiple owners report being told there is 'no fix' or 'no indication of safety concern' despite ongoing symptoms.
Unintended brake activation
Two separate incidents in which brakes applied without driver input while vehicle was in motion. One occurred near a railroad crossing at 45 mph with no brake pedal depression; another on the highway at 70 mph during what felt like limp mode.
When: One incident at ~1,500 miles; another at ~4,000 miles.
Symptoms owners cite: Abrupt, forceful brake application with no pedal input; Vehicle came to a complete stop or severely decelerated unexpectedly; Orange 'Brakes' warning light illuminated (one case); Engine entered limp mode; did not respond to throttle input (one case)
Repairs/costs cited: Dealers were unable to replicate the failures in both cases; no repairs were performed.
Recalls/TSBs owners mention: Manufacturer was notified; one owner reports the dealership said it was 'a known issue with no fix at this time.'
Cold-weather brake grabbing and squealing
Brakes squeal extremely loudly and feel like they grab or lock, particularly in cold months and when braking downhill or at low speeds. Noise is worse on first use after the vehicle sits, dissipates after a short drive, and returns within 30 minutes of shutdown.
When: Occurs seasonally (cold months only) and within 2–3 weeks of purchase.
Symptoms owners cite: Extremely loud squealing; Sensation of brake grab or locking, especially downhill; Occurs at any speed but worse at low speed; Noise goes away after vehicle warms up and driving time; Returns within 30 minutes of engine shutdown
Repairs/costs cited: Not specified in narratives; dealers were unable to replicate the condition.
Recalls/TSBs owners mention: Owner was referred to Client Services, which stated they were 'working on solution.' Later told dealer would need to resolve if issues present. No service bulletin or permanent fix offered.

A quarter of owners report trouble before 1,210; a quarter make it past 5,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
