2016 Hyundai Veloster: misfire or rough idle

Filed Jun 8, 2026 · Engine · TN

2016 Hyundai Veloster with 1.6L Gamma engine experienced repeat catastrophic engine failure consistent with the federal safety agency Recall 20V746000 / Hyundai Recall 198 for connecting rod bearing failure. Failure #1: At 124,036 miles, engine developed loud knocking noise increasing with RPM, check engine light, and DTCs P0300 (random misfire) + P0303 (cylinder 3 misfire). Dealer repair order documented "broken intake valve on cylinder 3." Engine was replaced at my expense because Hyundai stated VIN was not covered under Recall 198, despite failure mode matching the recall. Failure #2: Hyundai replacement engine failed at 164,410 miles (40,374 miles on replacement engine). Identical symptoms returned: loud metallic knock that increases with RPM, same DTCs P0300/P0303, misfire cylinder 3. Vehicle is currently inoperable. Safety Concern: the federal safety agency Recall 20V746 states connecting rod bearings "may wear prematurely, which over time can result in engine damage" and "can increase the risk of a fire." Both of my engines suffered catastrophic internal damage at ∼40k-50k mile intervals with identical codes and cylinder 3 failure. A broken intake valve is engine damage directly caused by bearing wear allowing piston-to-valve contact. This is a pattern defect. My VIN was excluded from the recall, yet suffered the exact failure twice. The replacement engine supplied by Hyundai had the same defect. This presents a safety risk of sudden engine stall, loss of power, or fire while driving. Requested Action: Investigation into why VINs experiencing the exact failure mode are excluded from Recall 20V746, and assistance obtaining remedy from Hyundai.

Incident Description: I purchased a 2016 Hyundai Veloster (VIN: KMHTC6ADXGU255844) in May 2025. Shortly after purchase, the vehicle began exhibiting serious mechanical issues, including engine knocking, excessive oil consumption, stalling, misfiring, and loss of power. Despite these ongoing issues, the vehicle is listed as having Recall 198 completed. However, the symptoms associated with that recall continued and progressively worsened. The vehicle ultimately stalled in traffic while I was making a turn, resulting in an accident. In a separate incident, after exiting the vehicle and believing it to be in PARK, the vehicle moved unexpectedly and ran over me, causing serious physical injuries including fractures. Prior to these incidents, the vehicle had ongoing mechanical issues that were not properly resolved. The vehicle also required repeated jump-starts and became unreliable to operate. Additionally, there are discrepancies in the service records. The vehicle was towed to a dealership on or about June 8, 2025 and remained there until approximately July 15, 2025. However, the documentation provided reflects only a limited number of service days and consolidates multiple visits into a single summary. Due to these inconsistencies and the continued presence of failure symptoms, I am unable to verify that recall-related repairs were properly performed. These incidents raise serious concerns about engine failure and possible unintended vehicle movement, both of which present significant safety risks.

There is a recall for 2016 Velosters that is for the engine rods failing. The 2015 to 2016 Hyundai Veloster has been recalled for connecting-rod bearings in the engine that could wear out prematurely and damage the engine1. The 2016 Hyundai Veloster has had several engine-related issues, including excessive oil consumption, going into limp mode, hesitating at acceleration, knocking sound in the engine, poor acceleration, stalling, failure in the timing chain tensioner, rough idling, and oil leaks. Which is exactly what is happening to my car currently. Told me I was not eligible. But I'm not understanding why.
