My 2016 LR4 with 54k on it was making a ticking noise. I brought it to the dealership, and they stated it was the high pressure fuel pumps. I was skeptical, but it was under warranty, so they moved forward with the repair. When I got the vehicle back, the ticking noise was still there, so it went back in, and I told them to check the timing chain. They replaced the timing chains, and I drove the vehicle for 400 miles until the other day when an engine bearing went. Now, they are saying it needs a new engine. Thoughts?
