y'all already covered the NUMMI part... the Vibe is basically a Matrix Cosplaying as a Pontiac. Both are essentially Corolla wagons.
The Vibe's were built at NUMMI, Matrices, somewhere in Canaidia...not sure if it was BC, or Ontario...
it's 95%+ Toyota, with a few GM components thrown in to mess things up.
My buddy put 120k on an '03 from 2010-2020, bought it summer of '03, w/120k mi. parked it summer 2020 when he picked up a 2012 Mazda 3
biggest problems he had (not caused by the accident it was in beforehand) were the blend door actuator stripping teeth, and clicking, HVAC blower only worked on HIGH( and yes we replaced both the blower motor,and the resistor.) he'd replaced the starter at least 3 times, but that could be from the shoddy accident repair...
and after 15 +yrs, and 200k mi, the ECU has an intermittent failure... some times it's fine, sometimes, no run...
and yes, the battery is basically wedged between the headlight, top rad hose, and air box. factory tie down is literally the same 2 j hook bolts and rubber/plastic handle universal deal you can buy in any parts store.
some burn oil, some don't. the filter (Fram **4967 for reference, is basically a Shorter **3416, and the **3600 may even clear..points straight down) with 4.5 qts of your finest 5w30.
I recall that NUMMI went down about the time that GM went under or a bit before. I've also read that only the Vibe version was made there with the Matrix produced in BC. I believe that plant is gone as well.
A friend had a had a '03 or '04 fwd Vibe for a great many years. He had pretty much trouble-free service from it. I'm not sure when the 2.4 engine became an option on the Matrix/Vibe/Corolla. Somewhere along the line on the 1.8, there had been a SB with an ECM reflash to reduce oil burning. Not sure how that worked.
