Common Hyundai Sonata Engine Problems

Many Hyundai Sonata engines fail because of internal wear, oil starvation, overheating or timing system problems.

• Engine knocking noise
• Rod bearing wear or failure
• Excessive oil consumption
• Timing chain or timing component failure
• Low compression
• Overheating damage
• Metal debris in engine oil
• Engine seizure

Our remanufacturing process helps correct these common issues by replacing worn internal components and machining critical engine surfaces back to OEM specifications.

Our Hyundai Sonata Engine Rebuilding Process

Every Hyundai Sonata engine is fully disassembled before rebuilding. Worn internal components are removed and replaced while reusable parts are cleaned, inspected and machined as required.

Engine blocks, cylinder heads, crankshafts and camshafts are professionally cleaned using thermal and/or chemical cleaning methods. Engine blocks and cylinder heads are inspected for cracks before machining and assembly.

Crankshaft Reconditioning

Crankshafts are ground and micro-polished as required to restore proper bearing clearances and surface finish.

Cylinder Boring & Honing

Cylinder walls are bored and honed to restore piston-to-wall clearances and compression performance.

Cylinder Head Remanufacturing

Cylinder heads are pressure tested, resurfaced and rebuilt using updated components when required.

Precision OEM Assembly

Every rebuilt Hyundai Sonata engine is assembled to OEM specifications using precision measurements and quality replacement components.
