Problem overview

Some Hyundai Sonata owners report experiencing low power on acceleration after multiple turbo replacements at 70,000 miles, which may be attributed to several potential issues. These owners have noted that replacing the Motor Driven Power Steering (MDPS) column could be necessary, as failure to do so might contribute to power loss. Additionally, problems with the fuel filter can lead to hesitation or jerking during acceleration, mimicking symptoms of a faulty fuel pump. Worn-out or fouled spark plugs have also been reported to cause misfires and reduced acceleration performance. Engine-related issues, such as excessive oil consumption and turbocharger failure, are common concerns among owners as well. Furthermore, some have experienced premature catalytic converter failure, often linked to misfires or faulty sensors. Lastly, a malfunctioning throttle body sensor can result in unexpected deceleration, affecting overall acceleration. It is recommended that owners seek a comprehensive inspection to accurately diagnose the cause of these performance issues.
