I have a 2013 LR4. I was curious if my LR4 would have this issue... so I compared the vin ranges.
---- (TSB DETAILS...)
TIMING CHAIN GUIDES ISSUE AJ133 5.0 V8
TSB LTB00474NAS3 19 MAY 2015 (section 303-01) Rattle/Click noise from front of engine
LR4 2010-2012 VIN AA513326 to CA652214
-----
My mid-2013 LR4 vin = *
I put a star next to where my vin is.. youll notice its NOT the latest and shares parts with the effected VIN range!. So my VIN is AFTER the end of the VINs on the TSB, but has some of the same part numbers. My only guess here is that the part numbers and vin ranges are not perfectly matched up somehow. I can't explain it. My 2013 *SHOULD* be safe, but based on my research I am not 100% certain.
