The failure pattern owners describe
The 2012 Veloster's electrical system is a minefield. The most common complaint across 32 narratives is HVAC blower fan speed control failure—the switch and wiring harness overheat and melt when set to high speed, causing burning plastic smell, failed cooling, and complete component failure. Multiple owners report the same part failed again after dealer replacement, with one owner having it replaced four times over two years. Hyundai has declined warranty coverage and repairs once extended warranty expires, despite owners finding melted connectors and charred wiring.
Cold-weather no-start occurs intermittently with just a single click and dead engine despite fully functional lights and radio. Dealers replace batteries and oxygen sensors without fixing the problem, which worsens below freezing.
Engine stalling while driving or stopped at lights, with unpredictable restarts, leaves owners stranded. One vehicle caught fire while accelerating. Post-recall service faults are documented: ECM updates caused 4000-RPM limiter, and throttle position sensor failures recurred after dealer replacement.
Melting of fuse panels, transmission wiring harnesses, and alternator harnesses have been found. The push-start button can crank the engine without clutch engagement on manual models—one incident involved a child accidentally starting the car while parked on an incline, sending it uncontrolled down a hillside. Rear seat belts stuck, airbag lights stayed on, and turn signals disable when steering. Owners report Hyundai refusing repair across multiple dealer visits.

Failure modes owners describe
HVAC blower fan speed control melting and burning
The blower motor fan speed control switch and wiring harness overheat and melt when set to high speed positions. The plastic control unit, connector, and wiring deform and char from excess current. Component fails intermittently or completely. Owners report burning plastic smell before failure. In some cases, the issue recurs even after replacement.
When: Varies; reported between 2000–91,000 miles; one case repeated failure after warranty replacement in 2015, then again in 2016
Symptoms owners cite: HVAC fan stops blowing or only works in certain positions; Burning plastic smell inside cabin; Control knob stops working entirely; Melted/charred wiring and connector; Grinding noise from control knob
Repairs/costs cited: Replacement of entire HVAC control unit; dealer quoted $500–$600; one owner noted the $5 internal part costs Hyundai $200+ as a complete unit; some dealers replaced the part multiple times (4 replacements reported over 2 years) with same failure recurring
Recalls/TSBs owners mention: Hyundai declined assistance, stated unwillingness to inspect failed parts or cover repair; one dealer quoted $140 diagnostic fee plus repair cost when extended warranty expired
Push-button start system allows engine to crank without clutch engaged
On manual-transmission models, the push-to-start button will crank the engine even when the clutch is not pressed in, allowing the car to lunge forward unexpectedly while parked. In one reported incident, a child activated the start button while the car was in first gear and unattended, causing the vehicle to lunge forward uncontrollably, crash through a fence, and down a hillside.
When: Observed on 2012 manual Veloster with push-start; incident occurred when vehicle was parked on incline
Symptoms owners cite: Engine starts without clutch being depressed; Vehicle lurches forward when stationary; Doors lock automatically after start; Wipers activate and drag across glass
Repairs/costs cited: No repair noted in complaint; safety system should prevent engine start without clutch engagement
Intermittent no-start with cold-weather sensitivity
Vehicle fails to start intermittently, particularly in cold weather. Owner hears a single click from the engine compartment when turning the ignition key, but engine does not engage. Lights and radio power on normally. Dealer replaced battery and oxygen sensor without resolving the issue. Problem worsens when temperature drops below freezing; improves in warmer conditions. Recurs within days to weeks of dealer visits.
When: First reported several weeks before complaint; cold weather (below –3°C) exacerbates; starts to fail at 91,000 miles
Symptoms owners cite: Single click sound when turning key; no engine engagement; All lights and radio turn on normally; Check engine light may illuminate; Beeping sound on ignition and engine shutdown (10 seconds followed by click); Multiple attempts needed to start; waits of 5–25 minutes reported; Worse in cold, improves with warmth

When: Immediately after ABS recall service
Symptoms owners cite: Check engine light illuminated; Unable to accelerate past 4000 RPM; Problem began immediately post-recall
Repairs/costs cited: Not repaired; owner requests inspection and fix at no cost
Throttle/pedal position sensor fault after recall service
Vehicle entered limp/protection mode after recall work. Dealer replaced throttle body but problem persists due to faulty throttle position pedal. Diagnostic codes P0222 and P0123 indicate throttle position sensor malfunction. Owner states problem began immediately after recall was completed. Low oil level was initially blamed, then spark plugs, but root cause is pedal/sensor.
When: Occurred 2 months after ABS recall; throttle body replacement during that window
Symptoms owners cite: Loss of power during driving (10 minutes after leaving recall shop); Throttle surging up and down; Vehicle entered protection/limp mode during vacation; Check engine codes P0222 and P0123 (throttle position pedal faults)

I contacted Hyundai motor of america to try to come to a resolution with an ongoing issue with veloster vehicles. Back in 2015, I had to have my HVAC fan speed controller replaced due to it intermittently working. The controller was replaced in march of 2015 under manufacturer warranty. Now in december of 2016, the fan speed control started to show the same symptoms as before. Then one evening it…
