Known problems with the 2014 Hyundai Sonata

3 of the 4 issues we track for the 2011–2014 generation are documented against the 2014 model year, and 2 carry a recall or service bulletin.

• Expanded Theta II recall, Knock Sensor Detection System, and lifetime engine warranty

  majorNHTSA 17V-226; Service Campaign 966 (KSDS); Nov. 2020 NHTSA consent order

  The 2015 recall proved too narrow to catch every affected engine, so Hyundai issued a second, broader Theta II campaign (17V-226) covering more 2011–2014 Sonatas, followed by a Knock Sensor Detection System (KSDS) software update (Service Campaign 966) that continuously monitors engine vibration for the same abnormal rod-bearing wear pattern and warns the driver before a seizure happens. After a November 2020 NHTSA consent order found Hyundai (and Kia) had run untimely recalls and misreported data, Hyundai extended a lifetime engine-replacement warranty to affected owners, but eligibility generally requires the KSDS update to be installed first, and owners report denials when it isn't on file.

  Typical cost: Free, KSDS install (Campaign 966), then lifetime short-block/engine coverage if the knock condition is later detected

• ABS module electrical short, engine-bay fire risk (Sonata Hybrid, recall)

  majorNHTSA 23V-651000

  On roughly 83,000 model-year 2011–2015 Sonata Hybrids, the ABS hydraulic control module (HECU) can develop an internal electrical short that increases the risk of an engine-compartment fire, whether the car is being driven, parked, or even turned off. Hyundai told owners to park outside and away from structures until the free dealer repair was completed as part of a wider, multi-nameplate 2023 Hyundai/Kia fire-risk recall.

  Typical cost: Free under recall

• 2.0T premature cylinder/piston wear

  moderate

  Separate from the connecting-rod-bearing recalls above, the turbocharged 2.0T Theta II has its own history of owner-reported premature wear, scored cylinder walls and damaged pistons in a subset of engines, often attributed to fuel washing down the cylinder walls on cold starts and short trips. There is no dedicated NHTSA recall for this pattern, and owners report mixed results getting it covered under the Theta II extended warranty.

  Typical cost: $5,000+ for a short block or engine replacement out of warranty
