The 2012 Hyundai Elantra comes equipped with a 1.8-liter naturally aspirated four-cylinder engine, designated as the Nu engine by Hyundai. This DOHC 16-valve engine produces 148 horsepower at 6,500 RPM and 131 lb-ft of torque at 4,700 RPM. The engine features aluminum construction with a cast iron cylinder liner and utilizes a timing chain rather than a belt. It’s paired with either a 6-speed manual or 6-speed automatic transmission and achieves EPA ratings of approximately 28 city/38 highway MPG with the automatic transmission.

The 2012 Hyundai Elantra shares most parts with the 2011-2016 model years, as they belong to the same fifth-generation platform. Engine components, transmission parts, suspension pieces, and most body panels interchange directly within this range. However, there were minor updates in 2014 that affected some electrical components and interior trim pieces. The 2017+ sixth-generation Elantra uses a completely different platform and has limited parts compatibility. For best fitment, stick within the 2011-2016 range, with 2011-2013 being nearly identical to the 2012 model year.

The 1.8L Nu engine in the 2012 Elantra has mixed reliability, with significant concerns about connecting rod bearing failures that can cause catastrophic engine damage. While many engines run well with proper maintenance, the bearing issue affects a substantial number of vehicles, particularly those with higher mileage. Regular oil changes every 5,000 miles with quality oil are crucial, as is monitoring for unusual engine noises or knocking sounds. The engine is otherwise mechanically simple with a timing chain that doesn’t require regular replacement like a timing belt would.
