The 2015 Azera with the 3.3L Lambda V6 is generally reliable, but this generation suffers from a catastrophic engine failure pattern tied to metallic debris from manufacturing—bearings starve, knock develops, and engines grenade without warning, often under 100k miles.
Symptoms: Sudden onset of loud knocking or ticking from lower end, Metal shavings in oil during changes, Loss of oil pressure, engine seizure in worst cases, Check engine light with low oil pressure codes
Fix: Complete engine replacement or rebuild required—connecting rod bearings spin due to metallic debris left from manufacturing process blocking oil passages. Rebuild involves full teardown, bearing replacement, crankshaft inspection/machining, typically 18-24 labor hours. Most shops recommend reman long-block swap at this point.
Estimated cost: $5,500-8,500
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Transmission fluid puddles under vehicle, usually passenger side, Pink or red fluid on driveway, Delayed shifts or slipping when fluid runs low, Burning smell if fluid contacts exhaust
Fix: Steel cooler lines corrode where they connect to radiator or run along subframe. Replace both lines as a set since they age together, includes dropping subframe or working around it. 2.5-3.5 hours labor.
Estimated cost: $400-700
6-Speed Automatic Transmission Mount Failure
Common · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Clunking on acceleration or deceleration, Vibration felt through cabin at idle in Drive, Excessive engine movement visible when shifting from Park to Drive
Fix: Hydraulic transmission mount collapses, allowing excessive powertrain movement. Relatively straightforward replacement but requires supporting engine/transmission. 1.5-2 hours labor.
Estimated cost: $250-450
ABS Module Failure (Recall Component)
Occasional · high severity
Symptoms: ABS and traction control warning lights illuminated, Loss of ABS function during panic stops, ESC/stability control disabled message, Brake pedal feels normal but no modulation during ABS events
Fix: ABS control module fails internally, sometimes due to moisture intrusion. Hyundai issued recall for some VINs; check eligibility first. If not covered, replacement requires bleeding entire brake system. 2-3 hours labor including programming.
Estimated cost: $800-1,400
Fuel Delivery System Contamination
Rare · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Hard starting, especially when hot, Rough idle and hesitation under load, Check engine light with fuel trim codes, Fuel odor in cabin or near tank
Fix: In-tank fuel filter (non-serviceable) clogs or fuel pump sock deteriorates, starving injectors. Requires dropping fuel tank, replacing pump assembly. Sometimes varnish buildup in lines from ethanol gas. 3-4 hours labor for pump R&R.
Estimated cost: $600-1,100
Head Gasket Leaks (Post-Overheat)
Rare · high severity
Typical onset: 100,000+ mi
Symptoms: White smoke from exhaust on cold start, Coolant consumption with no visible external leaks, Oil appears milky or frothy on dipstick, Overheating episodes, bubbling in coolant reservoir
Fix: Usually secondary failure after engine overheats from another issue (bad water pump, thermostat). Both head gaskets need replacement, heads checked for warpage and resurfaced. 14-18 hours labor for both banks on this transverse V6.
Estimated cost: $3,200-5,000
Owner tips
Change engine oil every 5,000 miles with quality filter—metallic debris issue makes oil analysis worthwhile every other change to catch bearing wear early
Inspect transmission cooler lines annually for surface rust; apply rust inhibitor to steel sections if caught early
Flush transmission fluid at 60k intervals despite 'lifetime fill' claim—helps prevent valve body issues
Check for open recalls on ABS module using VIN before buying used; Hyundai will fix for free if eligible
Solid daily driver if the engine hasn't been replaced yet—budget $6k-8k for potential engine grenade, or buy only with comprehensive warranty and confirmed clean oil analysis.

Hyundai Motor America (Hyundai) is recalling certain 2011-2015 Elantra, Genesis Coupe, Sonata Hybrid, 2012-2015 Accent, Azera, Veloster, 2013-2015 Elantra Coupe, Santa Fe, 2014-2015 Equus, 2010-2012 Veracruz, 2010-2013 Tucson, 2015 Tucson Fuel Cell, and 2013 Santa Fe Sport vehicles. The Anti-Lock Brake System (ABS) module may leak brake fluid internally and cause an electrical short, which can result in an engine compartment fire while parked or driving.
Consequence: An engine compartment fire while parked or driving can increase the risk of injury.
Remedy: Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the ABS fuse, free of charge. Owner notification letters were mailed April 10, 2024 through October 11, 2024. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 251.
