Looks like Lexus put them out around April/May this year...

I have the short forms only - when I track down a copy of the full TSB I'll post it in my TSB sticky at the top of this forum.

LEXUS: SOME VEHICLES MAY EXHIBIT A M.I.L. ON CONDITION WITH ONE OR MORE OF THE FOLLOWING DIAGNOSTIC TROUBLE CODES (DTC) STORED AS A RESULT OF AN IGNITION COIL MALFUNCTION: P0351-P0356 IGNITION COIL A-F PRIMARY/SECONDARY CIRCUIT. THE ENGINE MAY NOT START. *PE

Do you know if these apply to all years?

Umm..dunno. I'm at work now so I can't access the site where I normally grab the full TSBs and can't remember where I found the partial TSBs either.


**edit** Just checked nhtsa.dot.gov for 2006, 2007 and 2008 and it looks like the first TSB (for the freezing relay) applies to all years, but the TSB for the ignition coil is only for 2006.
