annualized failure rate

Dear Daniel,
in case you are a Keysight afficanado or professional, can you please inform me...
I have a new 34465a from Keysight in August 2021,
serial MY60016XXX
FW A.03.02-03
Might it have the serious potential issues with the MCU, storage etc mentioned and is likely to fail eg if left un powered for long periods?
Many thanks
Jon

Also they seem that changed the TI MCU (TM4C1292NCPDTI3 - G4), and what that seem to be an electric switch with a jumper. (see pics)
And they used for 34465A boards marked 34460.

Thanks for the mini-tear down skander36, do you know the manufacturing date of your unit?
@KeithFisk: I'm sorry to hear that your unit failed do quickly I'd be curious to hear how the story ended, did Keysight offer any assistance despite the device being out of warranty. Did you repair or replace the device?

I wasn't able to find production date, but calibration was done in Nov.2021, so it is very likely to be in second half of 2021.
After finding that analog board MCU and also left side MCU from digital front panel have been improved, along with tightened of the front panel, now I am confident that major causes for fails that was reported have been addressed.

I think your estimate is correct. AFAIK Keysight has a policy that devices that have been stored >6 months need to be sent back to KS (at least if you bought from an official KS partner). Thanks for taking the time to report back its good to know that devices manufactured >=Q3/2021 now use different hardware and thus may not be affected by the issue.
