2014 Hyundai Santa Fe brakes problems

ABS module fails internally, leaks hydraulic fluid, and creates fire hazard in engine compartment while parked or driving. Owners report smoke, burning smells, melted connectors, and wiring damage. Some vehicles caught fire; others had smoke in hood with ashes on battery and melted wiring around ABS system. Module failure occurs at low mileage (19,755 to 154,000 miles). Owners cite recall campaigns 20V520000, 23V651000, and 205 as related to this defect.

When: 19,755 miles to 154,000 miles; failure can occur after vehicle sits idle for extended periods

Symptoms owners cite: ABS warning light illuminates; Smoke or burning smell from engine compartment; Vehicle on fire while parked or driving; Melted wiring and connectors around ABS system; Ashes on battery; Brake fluid leak from ABS module brake lines; Vehicle fails to start after fire-related damage; Grinding or unusual noises from brakes

Codes mentioned: 20V520000, 23V651000, Campaign 205, Campaign 251

Repairs/costs cited: Owners report ABS module replacement required; some dealerships state pump failed first, causing ABS assembly failure. At least one invoice referenced repair under warranty. Replacement cost cited at $600+ for related crankshaft sensor. One owner reported pump and ABS assembly both failed under 30,000 miles. Parts for recall repair have been unavailable for extended periods (6+ months to over a year in many cases).

Recalls/TSBs owners mention: Hyundai issued recalls 20V520000, 23V651000, and 205 for ABS module and hydraulic brake issues. Recall campaigns advised owners to park vehicles outside and away from structures due to fire hazard. Recall repair parts were unavailable for months to over a year. Hyundai refused goodwill/reimbursement in at least one case. One owner reported that only fuse was replaced during recall work, not the ABS module itself. Hyundai did not provide tow trucks for recall repairs or loaner vehicles despite fire risk warnings.

Brake system loses all hydraulic pressure or fails to respond to pedal input while driving. Owners experience brake pedal becoming hard with no give, soft pedal, delayed stopping response, or complete inability to stop vehicle. Multiple collisions reported. No warning lights appear in some cases; warning lights appear in others.

When: 5 to 55 mph; at 89,060 to 106,000 miles; one case at 114,000 miles with ABS light previously illuminated

Symptoms owners cite: Brake pedal becomes hard or unresponsive; Soft brake pedal with excessive travel; Vehicle does not slow or stop when brakes applied; Requires excessive force on brake pedal to stop; Longer stopping distance than normal; No warning lights prior to failure; ABS and traction control warning lights illuminate in some cases; Check engine light illuminated in some cases; Vehicle vibrating while depressing brake pedal; Vehicle stalls during braking

Codes mentioned: 23V651000, 20V520000

Repairs/costs cited: Independent mechanic replaced brake seals and unknown brake parts in one case, but failure reoccurred. Another case required engine replacement (determined necessary by dealer but vehicle not repaired). One owner reported brake lines not tightened at factory; dealer tightened all 16 brake lines. No repair costs specified for most cases.

Recalls/TSBs owners mention: Recalls 23V651000 and 20V520000 issued for hydraulic service brakes. Parts unavailable for extended periods. Manufacturer made aware in some cases; no goodwill or reimbursement provided despite accidents and injuries. One case involved class action lawsuit on engine issues; brake failure followed engine replacement.

ABS control module connectors burn, melt, or become damaged by brake fluid intrusion. Wiring harness melts due to module failure. Burned connector found with brake fluid present. Multiple warning lights illuminate (ABS, traction control, hill descent control, blind spot detection cancelled message).

When: 19,755 miles; under 30,000 miles in one case; 83,000 to 110,000 miles in others

Symptoms owners cite: ABS warning light illuminates; Traction control warning light illuminates; Hill Descent control warning light illuminates; Multiple unidentified warning lights on dashboard; Blind Spot Detection Cancelled message displayed; Warning lights flicker while driving in rain; Speed sensor input errors on code scan; ABS unit stops communicating with diagnostic scan tool; Gauge operation erratic

Codes mentioned: Multiple codes stored in ABS for speed sensor input, 23V651000, 20V520000

Repairs/costs cited: One shop found brake fluid and burned connector when checking ABS control unit power and ground. Module and harness require replacement and module reprogramming. Dealers contacted but parts unavailable; vehicles not diagnosed or repaired in most cases.

Recalls/TSBs owners mention: Recalls 23V651000 and 20V520000 issued. Repair parts unavailable for extended periods. One shop noted that recall had not been expanded to that VIN but believed it should be. Manufacturer exceeded reasonable repair timeframe per multiple complaints.

Vehicle stalls while braking or at stop lights; crank position sensor fails in conjunction with brake system failures. In one documented case, crank sensor failed after recall repair work on ABS module, costing $600 to replace. Vehicle stalls without warning during normal braking operations.

When: During braking at stop lights and intersections; 95,000 miles; after ABS recall repair

Symptoms owners cite: Vehicle stalls while depressing brake pedal to stop; Stalling occurs at stop lights; Violent shaking when vehicle stalls; Intermittent starting problems; Engine light illuminates; Stalling recurs multiple times in short period

Codes mentioned: Crank position sensor failure code

Repairs/costs cited: Independent repair shop diagnosed and replaced crank position sensor for $600. After repair, vehicle failed to start again the next day. Owner associated failure with extended idle time during brake recall wait period and wear from sitting dormant for months.

Recalls/TSBs owners mention: Hyundai refused to provide goodwill warranty or reimbursement for crankshaft sensor repair, despite connection to recall-related idle period.

Hyundai issued multiple brake-related recalls (20V520000, 23V651000, 205, 251) but failed to supply replacement parts for months to over a year. Owners received recall notices advising immediate repair and parking restrictions due to fire hazard, but dealerships could not perform repairs. Many owners waiting 6+ months with vehicles parked outside in all weather, creating additional stress, damage, and safety concerns.

When: From at least August 2023 onward; delays reported from July 2021 through 2024+

Symptoms owners cite: Recall notice received but dealership states parts not available; Multiple dealership calls yield no parts availability; VIN tool confirms parts not available; Owners unable to park in garages per recall warning; Vehicle parked outside for months, exposed to weather and rodents; Rodents eating electrical wiring during extended outdoor parking
