Please help...
I have read pages and pages of good and bad feedback about the ECU/TRAC issue. My question is "how do I know my IS3 needs this update?". My car was purchased in Nov. 2000, I have 25K miles, and can't report any REAL issues.

WHAT ARE THE SIGNS OF ECU/TRAC PROBLEMS???

Thanks in advance

KCW

I cut and pasted this from a post awhile ago, I would assume it is still valid:

MORE IMPORTANT INFORMATION!!
The ECU reprogram update affects all IS300s whose VIN number is LOWER/BEFORE 10025186
The TRAC ECU replacement affects all IS300s whose VIN number is LOWER/BEFORE 10029014

my VIN# is above the range but I think I need the fix - hesistation & 'jerky' shifting. I'm going to inquire about it at my 1000 checkup.
