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.

The failure pattern owners describe
The 2009 Acura TSX has a consistent brake problem centered on the rear pads. Owners report rear brakes wearing out between 13,600 and 35,300 miles—many after only 8,500 to 10,000 miles of actual driving—while front brakes remain at 70% life or better. The inner pads on the rear wear faster than the outer ones. Dealers first claim this is normal wear or the owner's fault, then mention it's common for the model and recommend costly lifetime pad warranties. Acura eventually settled a lawsuit admitting to defective rear brake design that applies excessive force.
In cold weather (below freezing), owners report the brake pedal becomes rock-hard and immobile after overnight parking, preventing normal stopping. The pedal gradually softens after several minutes of driving or pumping. Acura's tech line speculated moisture freezes in the brake lines but couldn't explain the exact mechanism.
Owners also report premature front pad wear with squealing that starts within weeks, and one brake failure on a steep grade attributed to heat. Repair costs range from $200 to $412 per incident. Independent mechanics and multiple owners confirm the rear wear pattern is abnormal compared to other vehicles.

Failure modes owners describe
Premature rear brake pad wear
Rear brake pads wearing out far sooner than front pads or typical intervals. Inner pads on rear wheels wear faster than outer pads. Owners report replacement needed between 13,600 and 35,300 miles, with some warned at service visits as early as 10,000–17,000 miles that replacement is imminent.
When: 13,600–35,300 miles; inner rear pads reach wear sensor or critical thickness well before front pads show comparable wear
Symptoms owners cite: Rear brake pad wear reaching critical levels while front brakes remain at 70%+ life; Squealing and grinding noises from rear brakes; Inner/inboard rear pads wear faster than outer pads; Need for rear brake replacement despite primarily highway driving in some cases
Repairs/costs cited: $200–$412 for rear brake pad and sometimes rotor replacement at independent shops and dealers; owners report dealerships recommend lifetime pad warranties to offset recurring costs
Recalls/TSBs owners mention: Acura/Honda dealers initially claim excessive wear is 'normal wear and tear' or due to driving style. Canada issued a service bulletin for rear brake pad and caliper replacement. US models not formally recalled despite similar complaints. Honda settled a lawsuit over this exact defect involving 'defective design that caused excessive force to be applied to the vehicle's rear wheels.'
Cold-weather brake stiffness and failure
Brake pedal becomes hard and unresponsive in sub-freezing temperatures (single-digit Fahrenheit or below), typically after the vehicle has been parked overnight in cold weather. Pedal feels 'frozen' or stuck until after several minutes of driving or pumping the brakes.
When: Occurs when outdoor temperature drops into single digits Fahrenheit or during very cold overnight weather; happens on first application after cold soak
Symptoms owners cite: Brake pedal extremely hard and immobile or severely limited travel on first application after cold soak; Pedal feels like a brick, unresponsive to pressure; Brakes do not engage or provide minimal stopping force initially; Pedal gradually softens and normalizes after several pumps or several minutes of driving; Issue resolves for the rest of the day after initial warmup
Repairs/costs cited: Acura tech line suspected moisture freezing in brake lines; brake booster replacement performed in at least one case, later followed by replacement of supply line/check valve (reported on back-order in one case); no owner-cited repair cost
Recalls/TSBs owners mention: Acura dealerships initially had no experience with the issue and denied knowledge. Acura tech line suspected moisture ingress and freezing. Brake booster replaced in one case per tech line recommendation; supply line/check valve replacement ordered in another case but part was on back-order.
Brake failure on grade descent
Brakes fail to function properly when descending a steep hill, requiring emergency brake and downshift to stop vehicle. Failure attributed to excessive heat.
When: 40,300 miles
Symptoms owners cite: Brakes fail to function on steep downhill grade; Excessive heat generated during descent; Required emergency brake and downshift to stop vehicle
Repairs/costs cited: Vehicle was driven to dealer; no repair performed or cost cited
Front brake squealing and excessive wear
Front brake pads squeal persistently and wear excessively in some cases, with noise beginning within the first month of ownership.
When: As early as first month of ownership; excessive wear noted at 14,000 miles
Symptoms owners cite: Loud squealing noise from front brakes starting within first month; Excessive wear on front brake pads despite normal driving; Screeching and grinding noises during braking
Repairs/costs cited: $232–$350 for front brake pad replacement; service bulletin issued for squeaking brake repair
Recalls/TSBs owners mention: Dealer initially claimed squealing is normal for front brakes. Service bulletin issued addressing squeaking brakes.
