I want to share a few issues on the 400 I know about. Hopefully it can be helpful.
1. At 5k miles. Clicking, knocking, or rubbing noise from front end of car with wheels turned and rolling. (It got louder over weeks and I can hear it well at slow speed). Service advisor told me that the lug nuts were probably worn and Lotus issued new ones.
I swapped the front and rear lug nuts and it's quiet now! I will get the new Lotus or GRP ones. The front lug nuts were noticeably more worn.
2. Driver side window rattle - realigned by dealer at first service
3. My buddy had the small coolant housing tank leak issue while on the track which put the car in limp mode and check engine light came on.
4. His battery also died during another track day...It just died mid day while parked. New battery was the solution.
