C2417 on Hyundai by model: symptoms, diagnosis and fix
The Hyundai Ioniq's electronic parking brake (EPB) and Auto Hold feature can malfunction randomly, illuminating the EPB warning light and disabling the Auto Hold function. The EPB system uses brushed DC motors in the rear calipers that can fail prematurely, with diagnostic code C2417 indicating a motor short or open circuit. When the EPB faults, the Auto Hold feature (which automatically holds the brake at stops) also becomes unavailable, turning orange on the dashboard. The issue can be intermittent and difficult for dealers to reproduce, as the fault codes may not store permanently.
Common Symptoms
- Electronic Parking Brake warning light illuminates randomly
- Auto Hold indicator turns orange and feature is disabled
- EPB fails to engage when shifting to Park
- Grinding or clicking noise from rear brakes when EPB activates
- Smart Cruise Control becomes unavailable when EPB faults
How to Fix
Visit a Hyundai dealer and request a scan for code C2417. If present, the rear caliper EPB motor needs replacement ($400-$700 per caliper including labor). Both rear calipers should ideally be replaced together as the motors wear at similar rates. The dealer can also perform an EPB service mode reset after replacement. If the issue is intermittent and no codes are stored, ask the dealer to note the complaint in the service record for warranty tracking. The EPB calipers and motors are covered under the factory warranty.
Owner tips & cautions
- TipIf the EPB warning comes on intermittently, take a photo or video of the dashboard every time it happens. The dealer needs evidence that the issue is recurring if they cannot reproduce it during the service visit. Date-stamped photos strengthen your warranty claim.

Frequently asked questions
What does C2417 mean on a Hyundai?
C2417 stands for "Hill Start Assist System Fault." C2417 is a chassis code that the provided definition lists as a Hill Start Assist (hill-hold) system fault, a feature that briefly holds the brakes when you start off on an incline so the car doesn't roll back. The control module sets this code when it detects a problem within the hill-start-assist function or a related input it relies on, such as brake-pressure, incline, or wheel-speed data. You will typically see a warning message and lose the hill-hold feature, though normal braking still works. Note this is a manufacturer-specific code whose exact meaning and triggering component can vary by make, so the stored definition should be confirmed against the vehicle's service data. On Hyundai it is documented across 1 model: Ioniq.
What are the most common causes of C2417?
The most common causes of C2417 are: Fault or stored codes in the ABS/stability control module (shares the function), Faulty brake pressure or master cylinder pressure sensor, Inclination/yaw or accelerometer sensor fault, Wheel speed sensor signal problem, Brake pedal or brake light switch fault, Damaged wiring or connectors in the brake control system, Low brake fluid or hydraulic/electronic actuator issue. The specific cause varies by vehicle.
How much does it cost to fix C2417 on a Hyundai?
Published repair estimates on Hyundai range from $400 to $1,400 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
