What stands out
Owners have filed 31 engine 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 engine 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 engine 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.
Hyundai is conducting a campaign to enhance the knock sensor software to detect abnormal engine bearing noise before potentially severe engine damage occurs. If abnormal engine bearing noise is detected, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Engine Protection Mode allowing the customer to drive to the nearest Hyundai dealer for diagnosis and repair. In addition, DTC P132600 will be recorded in the ECM. The vehicle can continue to be operated for a limited time in Engine Protection Mode, but it will accelerate slower and have a reduced maximum speed. Engine RPMs will be limited to approximately 1800-2000 RPM.

full bulletin at NHTSA ↗A class action lawsuit against Hyundai Motor America (âHMAâ) alleges that certain Hyundai vehicles (âClass Vehiclesâ) were manufactured, marketed, sold, and/or leased with an engine defect that can result in sudden engine seizure, stalling, engine failure, and in some circumstances, engine fire, and that some owners and lessees of Class Vehicles have been improperly denied repairs under warranty. Neither HMA nor Hyundai Motor Company have been found liable for any of the claims alleged in the lawsuit. The parties have instead reached a voluntary settlement (the âSettlementâ) to avoid lengthy litigation and to provide owners of Class Vehicles certain benefits.

The failure pattern owners describe
The 2012 Hyundai Veloster engine failure complaints cluster around connecting rod bearing collapse, excessive oil burn, and catastrophic seizure. Owners report loud engine knocking—often the only warning—followed by sudden power loss, smoke, or complete shutdown, commonly at highway speeds. Failure occurs across a wide mileage span: some cars seize below 100,000 miles despite regular maintenance, while others make it past 150,000 before bearing failure punctures the block or fire ignites.
Oil consumption emerges as a precursor: multiple owners document rapid oil level drop (2–3 quarts in 2–3 weeks) without external leaks, forcing one shop to recommend 3,000-mile change intervals instead of the factory 5,000–7,000 mile spec. Check engine lights illuminate in some failures but remain dark in others, leaving owners unwarned. Owners cite $700 diagnostic fees, multiple engine replacements costing thousands, and Hyundai repair assistance denials, especially for second owners or those past the original powertrain warranty (5 years/60,000 miles).
One vehicle caught fire due to oil loss; another seized with two full engine replacements and an unresolved check engine light. Owners note that 2013 Veloster and related Kia models were recalled for identical bearing and fire-risk failures, yet the 2012 Veloster remains excluded from recall coverage.

Failure modes owners describe
Connecting rod bearing failure / engine knock
Connecting rod bearing failure leading to engine seizure, block puncture, or catastrophic engine damage. Owners report loud knocking sounds from the engine, often followed by loss of power, smoke, or complete engine failure.
When: Typically 75,000–200,000 miles; some failures occur without warning at highway speeds
Symptoms owners cite: Loud knocking or ticking noise from engine; Loss of engine power or inability to accelerate; Check engine light illumination (inconsistent; some failures occur without warning light); Smoke or burning smell from engine compartment; Engine stalls or shuts down mid-drive; In some cases, engine fire
Codes mentioned: P1326 (engine knock), P0420 (catalyst system efficiency), Compression test showing low PSI in cylinders
Repairs/costs cited: Engine replacement required. Owners cite costs ranging from $700 diagnostic fees to full engine replacement; one owner spent $5,000+ on repairs before denial. Some dealers unable to source replacement engines due to parts availability.
Recalls/TSBs owners mention: Hyundai has issued recalls for similar bearing failures on 2015–2016 Velosters but has not extended recall coverage to 2012 models despite identical engine design. Campaign Number 966 (knock sensor detection system software update) performed on some vehicles without resolving bearing failures. Hyundai has denied repair assistance requests from second owners or those outside limited warranty window.
Excessive oil consumption / internal oil burn
Engine burning or losing oil at abnormal rates without external leaks. Owners report oil level dropping rapidly between changes, often detected only when warning light comes on or spark plugs are found oil-soaked.
When: Can occur as early as 41,000 miles; most reports in 80,000–150,000 mile range
Symptoms owners cite: Oil warning light or low-oil indicator illuminates; Rapid oil level drop (2–3 quarts consumed in 2–3 weeks); No visible external oil leaks; Check engine light may accompany oil light; Spark plugs covered in oil when removed; Engine knocking follows consumption detection
Codes mentioned: P0171 or P0174 (fuel trim codes, secondary to oil burn), Oil pressure codes
Repairs/costs cited: Oil change intervals shortened to 3,000 miles (versus factory 5,000–7,000) by shops attempting to manage the problem. Hyundai diagnostic request: $700 charge with no repair assistance. One owner replaced engine out-of-pocket after Hyundai denied repair assistance claim.
Recalls/TSBs owners mention: Hyundai denies repair assistance to second owners or vehicles outside original warranty (typically 5 years/60,000 miles). No formal TSB or recall issued for oil consumption on 2012 Veloster; however, similar issues are part of larger Hyundai engine bearing recalls affecting 2013+ models and Kia siblings.
Loss of motive power / sudden stalling at highway speed
Engine suddenly loses power or stalls while driving, typically at highway speeds, forcing owners to coast to shoulder or exit. No consistent warning precedes failure; vehicle may restart temporarily.
When: Varies; reported at 128,000–150,000+ miles; one incident at ~2 years ownership on 2015 model year
Symptoms owners cite: Sudden loss of engine response to throttle pedal; Vehicle unable to maintain or exceed 35–60 MPH; Complete engine stall mid-drive; Inability to restart or delayed restart; No warning light in some cases; others show check engine or oil light after stall
Codes mentioned: Transmission failure codes (secondary diagnostic), Glow relay short circuit (misdiagnosed in at least one case)
Repairs/costs cited: Typically requires engine replacement. One owner paid $5,000 in repair attempts before engine replacement authorized. Dealer diagnostics sometimes inconclusive; vehicle stalls recur after dealer service.
Recalls/TSBs owners mention: Hyundai contacted in some cases; denied assistance in others. No specific recall or TSB identified for power loss on 2012 Veloster. Knock sensor software update (Campaign 966) performed on at least one vehicle without resolving underlying failure.
Engine fire
Engine fire caused by oil system failure and rapid oil loss. Owners report black smoke, flames, and total vehicle loss.
When: Within days of oil burn detection; one case 2 days after Pep Boys service
Symptoms owners cite: Black smoke visible from engine compartment; Flames coming from under hood; Rattling noise from engine preceding fire; Trail of oil on roadway before fire ignition
Codes mentioned: None applicable; total vehicle loss
Repairs/costs cited: Vehicle totaled. Fire department required to extinguish. One owner totaled 2012 Veloster; tow and fire suppression costs noted.
Recalls/TSBs owners mention: Owner later discovered 2013 Veloster recall for engine fire risk; 2012 model was not recalled despite identical engine design. No assistance offered in 2012 case.
Transmission engagement / shift failure (possible secondary to engine)
Vehicle fails to engage gear smoothly or shifts erratically. Symptoms include chugging, jerking, inability to go into gear, or need to cycle transmission to restore function. Dual-clutch transmission suspected by owners; however, engine knock and power loss are often concurrent.
When: Reported across wide mileage range; 41,000–150,000 miles
Symptoms owners cite: Vehicle will not engage into gear smoothly or at all; Chugging or jerking sensation when accelerating; Transmission will only shift into first gear or neutral; Vehicle must be cycled (neutral to drive, or restart) to restore function; Loss of power during gear engagement; Stalling during gear shifts
Codes mentioned: No codes in most reported cases
Repairs/costs cited: One owner spent $1,000 on fuel pump and engine mechanical repair with no resolution. Dealership unable to replicate failure or identify root cause after multiple visits.
Recalls/TSBs owners mention: Hyundai and dealers dismiss complaints; no recalls or TSBs issued. One owner notes online research shows hundreds of reports of dual-clutch transmission issues (random revving, unresponsive behavior) across Veloster forums.
Check engine light persistence
Check engine light remains illuminated or re-illuminates after service, repairs, software updates, and even engine replacement. Multiple engine replacements have failed to extinguish the warning.
When: Ongoing across service history; one case had two full engine replacements with light still on
Symptoms owners cite: Check engine light illuminated on dashboard; Light persists or returns after dealer reset/service; Software updates do not clear light; Light remains after engine replacement
Codes mentioned: P0171, P0174, P0420, P1326 (various), Emissions-related codes
Repairs/costs cited: Multiple service visits and two engine replacements in one case without resolution. Recalls and TSBs (including Campaign 966 software update) applied without extinguishing light.
Recalls/TSBs owners mention: Hyundai and dealers have no clear resolution strategy. One dealership scheduled multiple follow-up visits to address light without apparent success.

When stopped, car stalls occasionally.. Starts right up again, but then as I was driving car engine would occasionally feel as if it's going to stall & then surge up to power. *tr
I got a routine oil change at an old change place and then needed another one 2 1/2 weeks later. The employees at the shop informed me that my vehicle was burning through the oil extremely fast and that the oil dipstick was bare when they checked the oil level. They checked for leaks and found none. The very next day I started hearing a clicking noise coming from the engine and the check engine…
I was driving up to the mountains yesterday and my car began to make a knocking noise, my check engine light began to flash, the car turned off, and we had to basically let the car coast to an exit. Firestone said that my spark plugs 1,2,3 failed and my engine is knocking aggressively (code P1326).
