What stands out
Owners have filed 46 brakes complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA brakes complaint has been filed on this vehicle in over 9 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
Brake system failures on 2015 Dodge Darts cluster around two dominant patterns. The most common: brake booster failure with sudden loss of brake assist, requiring extreme pedal pressure or complete pedal stiffness. Owners report a characteristic hissing or air-release sound at the pedal, followed by the brake warning or "Service Electronic Braking System" message. Many lose brakes entirely while driving, forcing emergency brake deployment to avoid crashes.
The underlying cause in multiple narratives traces to engine oil migrating from the vacuum pump into the brake booster, degrading the diaphragm and destroying braking assist—identical to the issue in recalled 2013-2014 models. One owner's repair showed brake fluid leaking into the booster; another found a failed vacuum valve. The second pattern involves parking brake cable failure on manual-transmission models, preventing the vehicle from holding on inclines.
Brake booster parts sit on national backorder, extending repair timelines from weeks to months. Replacement costs range $400 to $1,200 when not covered by warranty. Multiple owners report the 2015 model year was excluded from the vacuum-pump recall despite exhibiting the identical failure modes. At least two accidents and one near-miss into oncoming traffic are documented. The problem surfaces across mileage ranges from 8,700 to 87,000 miles.

Failure modes owners describe
Brake Booster Failure (Oil Contamination)
Engine oil from the vacuum pump seeps into the brake booster, damaging the internal diaphragm. Loss of vacuum assist results in extremely hard brake pedal, requiring excessive force to stop. Characteristic hissing noise and air-release sound accompany pedal application. Vehicle may become un-driveable or require emergency brake to stop.
When: Typically 8,700 to 87,000 miles; 2015 models manufactured early 2015 onward
Symptoms owners cite: Brake pedal becomes rock hard or stiff; Hissing or air-release noise from brake pedal area; Loss of brake assist / no power brakes; Excessive pedal pressure required to stop; Brake pedal may push back against foot; Service Electronic Braking System warning light; Brake warning light illuminated; Murky, reddish-orange brake fluid; Air sounds when applying brakes
Codes mentioned: C0021, Service Electronic Braking System message
Repairs/costs cited: Brake booster replacement (often on national backorder for weeks to months); vacuum pump, vacuum line, and master cylinder replacement in some cases. Costs reported $400–$1,200+. Some owners cite dealership quote of $3,000.
Recalls/TSBs owners mention: Recall 15V800000 applies to 2013–2014 model years (not 2015); recall states parts were unavailable. 2015 models with identical symptoms excluded from recall.
Brake Booster Failure (Master Cylinder Leak)
Brake fluid leaks from the master cylinder into the brake booster, causing loss of brake assist. One owner reported this at 37,000 miles on a one-year-old vehicle, just outside warranty.
When: 1 year / 37,000 miles
Symptoms owners cite: Loss of power brakes / brake assist; Snap or sudden failure while driving; Brake pedal stiffness
Repairs/costs cited: Brake booster and master cylinder replacement required.
Recalls/TSBs owners mention: Warranty expired; manufacturer declined assistance.
Brake Booster Failure (Vacuum System Issues)
Failure of vacuum pump or vacuum lines leading to brake booster. One owner reported a broken valve in the hydraulic/vacuum system that caused oil to flood the booster. Another found a vacuum check valve malfunction.
When: Mileage varies; one documented at 72,260 miles
Symptoms owners cite: Abnormal air noise from brakes; Difficult-to-depress brake pedal; Vehicle fails to stop; Electronic Braking System warning on instrument panel; Brake pedal sinks with hissing noise then becomes hard
Codes mentioned: Electronic Braking System message
Repairs/costs cited: Brake booster, vacuum pump, vacuum hose, and brake lines replacement. Costs around $650–$1,200.
Recalls/TSBs owners mention: No specific manufacturer response; one owner received case number 57923582 but no further assistance provided.
Parking Brake Cable Failure (Manual Transmission Models)
Emergency/parking brake does not engage properly on manual-transmission 2015 Darts. Owner states the manufacturer did not properly install the parking brake cable. Vehicle rolls on inclines or in parking lots despite brake lever being pulled.
When: 45,000 miles reported
Symptoms owners cite: Emergency brake lever pulled but brake does not engage; Vehicle rolls backward on inclines; Vehicle rolls in parking lots with pedestrians present; Brake does not hold vehicle in park while in drive
Repairs/costs cited: Parking brake cable installation/repair; specific costs not stated.
Recalls/TSBs owners mention: No response documented; owner reports Chrysler fails to acknowledge the issue.
Rear Caliper Sticking / Dragging
Right or left rear caliper becomes stuck in engaged position, causing rotor to overheat and brake drag even when parking brake is released. Occurs repeatedly after repair.
When: 32,000–39,000 miles
Symptoms owners cite: Right or left rear caliper sticking; Extended parking brake handle travel required for engagement; Rear rotors glowing hot after short drive; Brake drag; Caliper repeats sticking after repair
Repairs/costs cited: Right rear caliper replacement at ~32,000 miles; left rear caliper sticking resumed at 39,000 miles. Rotor and pads also replaced.
Brake Pedal Intermittent Softness / Stiffness Cycling
Brake pedal alternates between soft and hard, or suddenly becomes soft while parked. One owner reported pedal depressing and pushing back when E-brake was set. Brake fluid may have air in the lines.
When: Various mileage; one instance noted while parked on a decline
Symptoms owners cite: Brake pedal goes from hard to soft spontaneously; Brake pedal depresses and pushes back against foot; Air in brake lines (suspected); Brakes catch on their own after going soft; Pedal has a kick-back; Jerking stop motion instead of smooth deceleration
Codes mentioned: Service Electronic Braking System warning
Repairs/costs cited: Front brake replacement in one instance; subsequent booster, vacuum hose, and pump replacement did not fully resolve the issue. $1,200 reported for second repair.
Complete Brake Failure While Parked
Vehicle rolls despite brake pedal being applied or parking brake being engaged. One documented instance: vehicle started rolling forward while parked, eventually crashed into a gate.
When: One instance on unknown mileage
Symptoms owners cite: Vehicle rolls forward despite brake pedal applied; Vehicle continues rolling when shifted to park; No warning lights illuminated; Parking brake does not prevent rolling
Repairs/costs cited: Not diagnosed or repaired by owner; vehicle crashed into gate.
Recalls/TSBs owners mention: Owner received notification of NHTSA Campaign 25V674000 (Power Train), but recall parts were unavailable.
