Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits
and driving conditions shift the curve as much as mileage alone.
An engine compartment fire while parked or driving can increase the risk of injury.

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
Owners describe two major brake failure patterns. Most common: the hydraulic control unit failure tied to recall 23V652000, where Kia issued repair notices but parts remained unavailable for extended periods—some owners had notices for months or years. When the HECU fails, vehicles produce smoke from the engine bay, stall without warning, and refuse to restart; a few cases involved no warning lights beforehand. Several owners at 56,000 miles experienced smoke and immobility.
Secondary issues cluster around the parking brake, auto hold system, and brake booster. One owner had the parking brake stick and auto hold lock up the brakes completely at 44,000 miles, requiring towing in reverse only. That same owner had replaced a parking brake sensor previously. Another reported brake booster check valve failure twice—once within a month of purchase, again at 61,000 miles when the dealer declined warranty coverage and the OEM part was unavailable, forcing sourcing from Hyundai. Two owners reported hesitation on acceleration and surge when turning after brake work or windshield repairs, a symptom that persisted despite multiple repairs. One case involved an accelerator that stuck and brakes that failed to stop the vehicle four times; no dealer could replicate or fix it. Water intrusion from windshield seal failures compounded some of these issues by corroding brake components and interior electronics.
Failure modes owners describe
Hydraulic Electronic Control Unit (HECU) Failure / Recall 23V652000 Parts Unavailability
Multiple owners reported receiving recall notice 23V652000 (Service Brakes, Hydraulic) but unable to complete repairs due to unavailable parts. Several cases involved smoke from engine compartment, stalling, erratic electronics, and illuminated ABS/check engine lights. One owner experienced smoke and inability to restart at 56,000 miles; another at 56,002 miles. Parts unavailability persisted beyond what owners considered reasonable timeframes, stranding vehicles in unsafe conditions.
When: 56,000–117,000 miles; recall notification arrived but parts on backorder indefinitely
Symptoms owners cite: Smoke from engine compartment; Vehicle stalling and failure to restart; Erratic electronics behavior; ABS warning light illuminated; Check engine light illuminated; No warning lights in some cases despite failures
Repairs/costs cited: Recall 23V652000 parts not available; vehicle not repaired due to parts unavailability. Hydraulic electronic control unit identified as failed component in at least one case.
Recalls/TSBs owners mention: NHTSA Campaign Number 23V652000 (Service Brakes, Hydraulic) issued; manufacturer confirmed parts unavailable; owners advised to contact NHTSA hotline in some cases.
Power Brake Booster Check Valve Failure
Brake booster check valve failed twice on one vehicle. First failure occurred within the first month of ownership, causing loss of vacuum and occasional hard pedal during braking after acceleration. Replaced under warranty. Second failure occurred at 61,000 miles; dealer refused warranty coverage and charged diagnostic fee. Owner had to source replacement part from Hyundai due to Kia unavailability.
When: Within first month of ownership; second occurrence at 61,000 miles
Symptoms owners cite: Loss of vacuum after as little as one hour after driving; Occasional hard pedal during braking after acceleration
Repairs/costs cited: Part # 591391C200 Brake Vacuum Hose Connector replaced under warranty first time; second replacement required at 61,000 miles, not covered under warranty. Owner sourced part from Hyundai because Kia part was unavailable.
Parking Brake / Auto Hold System Lock-Up with ABS Activation
Parking brake stuck and required manual disengagement; subsequent attempts to drive triggered auto hold yellow warning light and ABS activation, locking the brakes. Owner could only be towed in reverse because front brakes locked. Internet forums indicate this is a known pattern around 36,000–44,000 miles, often attributed to dirt and moisture entering the brake system. Owner had previously replaced parking brake sensor once.
When: 44,080 miles; similar issues reported at 36,000+ miles
Symptoms owners cite: Parking brake stuck; Auto hold yellow warning light illuminated; ABS activated; Complete brake lock-up preventing forward driving; Brakes only disengaged enough for rear towing
Repairs/costs cited: Parking brake sensor previously replaced. Owner suspects dirt and moisture entering brake system based on forum discussions; dealer has not definitively diagnosed the auto hold lock-up issue.
Brake System Failures with Hesitation and Surge
Two owners reported vehicle hesitation before accelerating and surge/jump forward when turning left or right. One case linked to water leak damage from defective windshield adhesion; the other after brake recall repair. Hesitation and surge persisted even after windshield replacement, defogger sensor replacement, and brake recall repairs completed.
When: 41,000 miles in both reported cases
Symptoms owners cite: Vehicle hesitation before accelerating; Brief stop then surge/jump forward when turning left or right; Symptoms persisted after multiple repairs
Repairs/costs cited: Windshield replaced (twice in one case); defogger sensor replaced; brake recall repair completed; hesitation and surge symptoms persisted despite all repairs.
Recalls/TSBs owners mention: NHTSA Campaign Numbers 23V652000 and 22V158000; manufacturer opened cases but underlying hesitation/surge issue unresolved.
Brake Pedal Ineffectiveness / Accelerator Stuck
One owner reported accelerator stuck and foot brake unable to stop the vehicle on four separate occasions. Dealerships unable to replicate the failure across two Kia dealerships and the selling dealer. Owner managed stops by shifting to neutral and applying foot brake. No diagnosis or repair provided.
When: Occurred 4 times; no mileage specified
Symptoms owners cite: Accelerator stuck; Foot brake ineffective at stopping vehicle; Unable to replicate by technicians
Repairs/costs cited: No diagnosis or repair completed; failure could not be replicated.
