What stands out
No new NHTSA brakes complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
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
Ten complaints describe brake failures spanning corrosion, pressure loss, and component wear. The most widespread issue is brake line corrosion identified in a Kia recall. Multiple owners received inspection letters (dated 8/19/22 and 12/8/22) directing them to dealerships where severe rust and pitting were documented. Dealers confirmed replacement was needed and safety-critical, but parts remained on back-order for months with no arrival timeline. Owners report contacting Kia customer service and multiple dealerships with no resolution—one customer waited nearly two months post-inspection, another couldn't reach anyone after hour-long holds. One owner reports Kia suggested third-party repair with reimbursement, but shops couldn't source parts either.
Separately, three owners describe complete brake failure during operation: pedals going to the floor with zero stopping power at a four-way stop, during low-speed braking, and on an incline. One involved a piston blowout and fluid loss; another required brake line replacement that didn't resolve the issue.
One complaint describes both front calipers frozen/seized, producing noise and causing excessive wear to wheel bearing, pads, and rear brakes as the vehicle over-compensated. Another owner found rear brakes worn to the rotor at 40,400 miles on a certified Kia.

Failure modes owners describe
Brake line corrosion and rupture
Brake lines develop rust/corrosion leading to leaks and complete brake fluid loss during operation, rendering brakes inoperative.
When: Multiple mileages cited; one at ~56,334 miles. Recall inspection letters dated 8/19/22 and 12/8/22 identified severely rotted lines.
Symptoms owners cite: Brake pedal unresponsive despite depression; Brake light illumination; Complete loss of braking power; Brake fluid leaking from corroded brake lines; Vehicle unsafe to drive per dealership notation
Repairs/costs cited: Brake line replacement required. Parts persistently on back order from manufacturer as of complaint dates (late 2022). Owners report waiting 2+ months with no ETA. Third-party repair not readily available; Kia suggested reimbursement route but owners unable to execute.
Recalls/TSBs owners mention: Kia issued voluntary recall to inspect/repair brake line corrosion. Owners report recall letter stated repair would be made at no charge. However, parts have been on back order for extended periods with no resolution. One owner reports Kia claimed responsibility would shift to owner if failure occurs during parts delay.
Brake pedal loss of pressure (spongy/goes to floor)
Brake pedal loses pressure and travels to the floor with minimal or no braking response, presenting imminent collision hazard.
When: Occurred during normal braking operations; one incident at 5 MPH, another at four-way stop, another on incline.
Symptoms owners cite: Brake pedal depressed but no stopping power; Brake pedal travels fully to floor; Loss of all braking on inclines or bumpy pavement; Loss of braking during low-speed maneuvers
Repairs/costs cited: One owner reported vehicle taken to dealer, brake lines replaced, but failure persisted post-repair. One incident involved piston blowout with fluid leakage.
Frozen/broken front brake calipers
Front calipers seize or break, producing strange noise and causing uneven braking that leads to cascading wear on other brake components.
When: Issue identified after owner brought vehicle to dealer 3 times over span of one year for noise complaint.
Symptoms owners cite: Strange sound while vehicle in motion; Frozen/broken front calipers; Excessive wear on brake pads, wheel bearing, and rear brakes as vehicle compensates
Repairs/costs cited: Both front calipers replaced. However, by time issue was diagnosed, front left wheel bearing, front brake pads, and rear brakes had already been replaced as customer and shop over-compensated for the undiagnosed caliper failure.
Premature brake pad and rotor wear
Brake pads and rotors wear excessively early in vehicle life, with rear brakes worn into the rotors and front brakes beginning same wear pattern.
When: Identified at 40,400 miles on a certified used 2015 Forte that had 32,500 miles at purchase.
Symptoms owners cite: Rear brake pads worn completely into rotors; Front brake pads beginning to wear into rotors
Repairs/costs cited: Rear brakes required replacement; front brakes anticipated to need replacement soon. Owner questions condition of brake pads at time of Kia certification.

What owners are reporting 1 most recent
Received inspection letter dated 8/19/22 from Kia to inspect/replace if necessary brake line. First available appointment was 9/27/22. Inspection revealed a severely rotted brake line and invoice notation that vehicle is unsafe to drive. I contacted 3 other Kia dealerships and was given the familiar response that the parts are on back order with not estimate time for arrival. I contacted Kia…
