2016 Hyundai Elantra

Engine complaints dominate the 2016 Elantra's owner reports by a wide margin. The most common pattern is unexpected engine stalls, owners frequently describe the engine shutting off without warning while driving, including at highway speeds and in active traffic. Related to this, a number of owners report hard or no-start conditions, sometimes accompanied by a crankshaft position sensor code, and in some cases the sensor has been replaced only for the same symptom to return. A smaller group reports internal engine noises, particularly a rhythmic ticking consistent with what owners associate with connecting rod or bearing wear. Powertrain complaints are the second-most-reported category, with owners describing rough or hesitant behavior. Airbag-system complaints also appear in meaningful volume, though the engine stall and no-start pattern is clearly the most consistent thread across the complaint set.
