2012 Hyundai Elantra parts and specs

What changed for the 2012 Hyundai Elantra

• 2012MD generation launch (sedan only)

Known problems with the 2012 Hyundai Elantra

5 of the 5 issues we track for the 2012–2016 generation are documented against the 2012 model year, and 4 carry a recall or service bulletin.

• ABS module internal brake-fluid leak / engine bay fire risk (recall)

  majorNHTSA 23V-651 (Hyundai internal number similar)

  The ABS module's internal circuit board can develop a short from a slow internal brake-fluid leak, which in the worst case causes an engine-compartment fire, while parked or while driving. Hyundai recalled roughly 189,000 model-year 2011–2015 Elantra/Elantra GT/Coupe vehicles in 2023; dealers inspect and replace the ABS module and a related fuse, free of charge.

  Typical cost: Free under recall

• Nu-engine oil consumption / tick and warranty-extension settlement

  moderateHyundai Engine II class-action settlement (2022); check VIN eligibility at hma-e2settlement.com

  A subset of 1.8L/2.0L Nu engines burn oil faster than spec or develop an audible tick, prompting owner complaints and a 2022 class-action settlement ("Hyundai Engine II") that extended warranty coverage for qualifying engine failures on Nu- and Lambda-family engines. It is far less severe and less common than the Theta II bearing-failure/engine-fire issue on Sonata and Santa Fe of the same years. Don't conflate the two, but it's worth checking oil level between changes on a used example.

  Typical cost: $0 (oil top-offs) to $3,000–$5,000 for an out-of-warranty short block

• Electronic stability control unintended braking (recall)

  moderateNHTSA 15V-871

  A malfunctioning ESC wheel-speed sensor can cause the brakes on one or more wheels to apply unexpectedly, increasing crash risk. Hyundai recalled 2011–2012 Elantras (carrying into early MD production); dealers reprogram the ESC module.

  Typical cost: Free under recall

• Side curtain airbag headliner bracket displacement (recall)

  moderateNHTSA 13V-115

  The support bracket that anchors the headliner during a side curtain airbag deployment can become displaced, raising the risk of an occupant laceration injury in a side-impact crash. Dealers install a reinforcement free of charge.

  Typical cost: Free under recall

• Panoramic sunroof rattles and wind noise (owner-reported)

  minor

  Cars with the optional panoramic sunroof commonly develop rattles from the sunshade track and wind noise at highway speed as the seals age. Not a safety issue; dealer adjustment or aftermarket felt/seal kits usually resolve it.

  Typical cost: $0 (DIY seal kit) to $200 (dealer adjustment)
