Nissan Faces Class Action Lawsuit Over Variable Compression Engine Failures

How the Variable Compression Engine Works

The VC-Turbo engine was designed to deliver both power and fuel efficiency by adjusting compression ratios on demand. Using a multi-link system with dual connecting rods, the engine could switch between high compression for performance and lower compression for efficiency.

However, this intricate mechanism appears to have contributed to premature wear on engine bearings, particularly those supporting the adjustment system and crankshaft. Nissan’s recall notice admitted that faulty bearings in these engines could result in engine damage or total failure.

What the Lawsuit Seeks

The class action aims to expand the recall to cover additional model years and secure compensation for affected owners. Plaintiffs are demanding financial damages, though exact amounts remain undisclosed.

Interestingly, Nissan still continues to use VC-series engines in multiple vehicles, despite the recall. NHTSA’s filing estimated that only about 1.2% of the recalled units are likely to experience catastrophic failure—but with nearly half a million vehicles recalled, the potential impact is significant.

What This Means for Owners

For Nissan and Infiniti owners with VC-Turbo engines, the lawsuit could determine whether repairs and replacements are covered more comprehensively. While the technology promised efficiency and innovation, its future now depends on how Nissan handles both the recall and legal proceedings.
