Frequently Asked Questions:

Q: How does the eAssist system work?

A: The eAssist mild hybrid system gives extra power when you accelerate, smooths engine stops and starts at traffic lights, and captures braking energy to recharge a small battery. It doesn’t support full electric driving.

Q: Does the eAssist system require special maintenance?

A: Beyond standard engine and transmission maintenance, the eAssist system's main component to monitor is the lithium-ion battery pack. While designed for longevity, its performance can degrade over time. No specific routine maintenance for the electric motor itself is typically required.

Q: What type of transmission does the 2012-2016 Lacrosse eAssist use?

A: It uses a 6-speed automatic transmission, specifically tuned to integrate with the eAssist system for smooth transitions.

Q: Can I run this engine without the eAssist system?

A: While the gasoline engine is the primary power source, the eAssist system is deeply integrated into the vehicle's electrical and control systems. Running the engine without the eAssist components fully operational or connected is not feasible without significant modifications and could lead to numerous fault codes and drivability issues.
