Proton S70 Common Problems Malaysia

Proton S70 · 2023–present

Proton S70 (2023+): DCT shudder on the 7-speed wet DCT — same family as X50 DCT. DCT fluid every 40,000 km is critical. Carbon buildup from 1.5T 3-cylinder direct injection at 60,000–80,000 km. 3-cylinder vibration at idle is characteristic, not a fault. Software update history important — early units may need Proton SC calibration update. First Proton sedan in years: parts sourcing developing.
