The failure pattern owners describe
The 2010 Accent shows a pattern of electrical gremlins that owners didn't bargain for. Brake light switch failures top the list—all three brake lights go dark, bulbs and fuses check out fine, and replacing them won't help. Owners had to foot repair bills at dealers despite Hyundai excluding 2010 from the recall that covered 2007–2009 models. Multiple complaints confirm the switch is the culprit; some failures started intermittently then went complete.
Exterior lighting misbehaves in other ways too: tail lights, hazard lights, and turn signals fail intermittently, often disappearing during diagnostic testing so mechanics can't pin down the problem. Engine stalling is another complaint—vehicle quits at traffic lights, electrical system stays partially alive, and only jumper cables get it running again. One owner dealt with this twice.
The oil level indicator flickered instead of staying on when oil ran low, and the tachometer quit working after a separate incident. A few owners report wiring issues that could genuinely be dangerous: HVAC blower wiring melting and burning (owner smells plastic burning), and smoke rising from the steering column during normal driving. One owner also mentioned replacing three coil wires early on.

Failure modes owners describe
Brake Light Switch Failure
Brake light pedal switch fails prematurely, causing all brake lights to stop illuminating. Some complaints note intermittent failure progressing to complete failure.
When: Various mileages reported; one complaint notes intermittent failure ~10,000 miles prior to complete failure
Symptoms owners cite: All three brake lights out; Brake lights do not illuminate when pedal is pressed; Bulbs and fuses are intact but lights still non-functional; Intermittent brake light failures
Repairs/costs cited: Dealer replaced defective switch with revised switch; owners had to pay for repair. Bulb and fuse replacement did not resolve issue.
Recalls/TSBs owners mention: Hyundai stated 2010 Accent was not part of recall campaign for brake light switch (recall covered 2007–2009 models). NHTSA campaign 15V566000 (Exterior Lighting) referenced but 2010 model not included in coverage.
Oil Level Indicator Malfunction
Oil level warning light flickers intermittently or fails to stay illuminated when oil is low, creating risk of engine damage. Light may fail to activate despite actual low oil condition.
When: At least two separate occasions reported by same owner
Symptoms owners cite: Oil indicator light flickers instead of staying on; Light goes out despite low oil condition; Check engine light comes on after apparent oil-related stall
Codes mentioned: Crank sensor issue detected after check engine light activated
Repairs/costs cited: No specific repair noted for indicator itself. Engine stalled due to lack of oil; shop changed oil. Crank sensor failure identified separately.
Tachometer Failure
Tachometer stops functioning, often appearing alongside check engine light activation. Exact root cause unclear but timing suggests electrical system involvement.
When: Two days after oil-related stall incident
Symptoms owners cite: Tachometer does not function; Check engine light comes on simultaneously
Codes mentioned: Crank sensor fault identified
Exterior Lighting Failures (Tail, Hazard, Turn Signals)
Tail lights, hazard lights, and turn signal lights fail intermittently or completely. Failures may be intermittent and difficult to diagnose.
When: At 35,001 miles; also reported at 60,000 miles
Symptoms owners cite: Tail lights fail; Hazard lights fail; Turn signal lights fail; All interior and exterior lights fail simultaneously; Intermittent failures that do not repeat during diagnostic testing
Repairs/costs cited: Mechanic unable to duplicate failure during diagnostic; no fault codes generated.
Recalls/TSBs owners mention: NHTSA campaign 15V566000 (Exterior Lighting) and 13V113000 (Exterior Lighting, Service Brakes, Hydraulic) referenced; however, VIN may not have been included in campaign coverage.
Engine Stall - Electrical Cause
Engine stalls and will not restart via normal ignition procedure. Electrical system remains partially functional (flashers work). Only workaround is jump-starting vehicle.
When: At least two separate incidents reported by one owner
Symptoms owners cite: Engine stops at red light and will not restart; Flashers and electrical system still operational; Key removal and reinsertion does not resolve issue; Jump-starting restores normal operation
Repairs/costs cited: Owner uses jumper cables to restart vehicle; issue resolves after jump-start.
HVAC Blower Motor Wiring Overheat / Melting
Wiring connection between blower motor and HVAC resistor melts and burns. Plastic female plug connector shows burn marks and discoloration.
When: Not specified
Symptoms owners cite: Burn marks on plastic connector plug; Smell of burning plastic from HVAC system; Resistor malfunction forces owner to use blower at maximum speed to bypass resistor
Repairs/costs cited: Owner works around issue by running blower motor at maximum speed to avoid resistor use.
Steering Column Smoke / Electrical Fire Risk
Thin wisp of smoke appears from steering column area during normal driving. Suspected electrical fire hazard.
When: After approximately 5 minutes of driving; after 2 right turns
Symptoms owners cite: Thin wisp of smoke from steering column or near steering column (left side)
Ignition Coil Wire Failures
Multiple ignition coil wires fail prematurely. Hyundai service imposed unusual service requirement: replacement of spark plugs mandatory before third coil wire could be replaced.
When: Early in vehicle ownership; third wire failure required spark plug replacement first
Symptoms owners cite: Ignition coil wire failure
Repairs/costs cited: Three coil wires replaced. First two replaced by Hyundai; third replacement required owner to first replace spark plugs per Hyundai service requirement.
Recalls/TSBs owners mention: Hyundai service imposed requirement that spark plugs be replaced before third coil wire replacement could proceed.

While my vehicle was in motion, driving straight after 2 right turns, after approximately 5 minutes of driving, a thin wisp of smoke rose up from my steering column, or near my steering column, on the left side. From my general google research, this appears to be an electrical problem. *tr
The brake lamp switch became defective intermittently, approximately 10,000 miles ago. It has now failed completely. Apparently I am not the only one experiencing this problem: http://www.autoblog.com/2013/04/03/Hyundai-Kia-recalling-1-6m-more-models-for-faulty-brake-switch/ this is a serious problem, so I wanted you to know. *tr
My brake lights are all out. All 3. I did some research and found that some cars up until 2009 were recalled for a faulty brake light switch. I am fearful I could put myself or others in harms way. This is a definite safety issue with this vehicle. I am not sure if there are currently other reports but I am doing so now. I am taking it to the dealership asap to have it evaluated. A…

At what mileage does the electrical typically fail?
Across the 9 complaints that reported odometer mileage, most electrical failures cluster between 46,000 and 63,411 miles, with the median around 52,184. A quarter of owners report trouble before 46,000; a quarter make it past 63,411. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
