05 MDX TPMS light issue (TSB 05-023)
I have an 05 MDX (60000 miles) with the TPMS light coming on intermittently (note this is the 'TPMS' indicator light itself, not the tire lights). There is no consistency to it, tire pressures are fine. If it's on and I turn the car off and back on it will go off and may come back on an hour later or 10 days later. I saw TSB 05-023 which sounds like it may describe the problem, but when I called my local dealer they said they won't do anything without the $109 diagnostic check.
IMHO if TPMS is working 90% of the time then I'd just assume ignore it, but if the TSB has any useful information in it on a) how to fix it and b) whether it's something serious and I really should get it fixed, I'd like to know.
Any help, advice, or redirects to threads with more info on this issue would be appreciated.
