*Extreme Conjecture Below*
I wanted to see if I could ballpark the failure rate of the radiator through the use of the information on this forum and the internet as well as narrow down the timing of the failures. On this thread alone, the following users have had radiator failures/ cracking (complete with model year and miles listed are as of the event date):
@jclarke450 - 08 at 166K miles
@INTP - 08 at 143K
@NetJunky - 09 at 135k
@BTUMAN - 08 at 94K
@MEMCruiser - 08 at 185K
@Softride62 - 08 at 110K
@DSallean - 08 at 129K

I was able to find two additional cases of radiator failure in another 200 section thread.

Number of Failures:
14 total failures, 10 were 2008 model, 1 was 2009, 1 was 2011, and 2 unknown. All are Land Cruisers except for the 2011 LX 570 despite them using the same radiator. This could be because the 200 section is mainly LC owners. I checked the 3rd gen LX 570 section on clublexus but wasn't able to find any failures.
Mileage of Failures:
Failures occurred at an average of ~123,000 miles with a standard deviation of ~31,000 miles (numbers only take into account vehicles who's mileage at the failure was recorded). All are believed to have occurred within the last two years.
Failure Rate:
There is no way a good baseline for failure rate. The MUD population is too small and there is no way to accurately count the number of owners of the 08-11 model year. This thread shows 71 currently owned from 2008-2011 (
How many 200's on ih8mud). Assuming all MUD owners input their info (which didn't happen and is a bad assumption), this puts the failure rate at ~20% (take with a Land Cruiser-sized grain of salt)
