PIC #1:
This PIC is in regards to the front strut bearings, which could result in a popping noise from the front suspension while turning. Coil spring witness marks are to be checked and if any rubbing is found on the coils, the springs are to be replaced. The strut bearing is to be inspected and dark streak marks are to be looked for. If any marks are found which could indicate slippage, the entire strut bearing assembly should be replaced. The goal of this document is to help the technician identify the problem. The parts for replacement are the same as when it left the factory and there is not an alternative service method. This is not a TSB.

IB #1:
This information bulletin is in regards to warranty claims being made for the 175A battery harness fusible link being replaced under warranty. It advises dealers to check if the under hood fuse block positive terminal has been used to jumpstart a vehicle, instead of using the correct connections on the drivers side of the engine compartment. If found to be used for jumpstarting, they will deny your warranty claim. So stay away from the grey covered terminal on the passenger side fuse/relay block.
