Pre-purchase inspection · 2021 Volkswagen ID.4
ID.4 had multiple NHTSA recalls including defective rear defroster causing fire risk, software-related loss of regen braking, and infotainment defects.
Run VIN at nhtsa.gov/recalls. Multiple open recalls on a 2021–2022 = seller has not maintained the vehicle properly.

The ID.4 (like many modern EVs) uses a small 12V battery for low-voltage systems. VW sizes it undersized and these fail frequently, stranding the vehicle. This is the most common ID.4 repair.
Test 12V battery health at purchase (any battery tester works). Ask if it has been replaced.
Est. cost: $250–$400 12V AGM battery replacement

This one is a correction to the usual advice: on a 2021 ID.4 the 8th VIN digit tells you nothing. It is invariant across Volkswagen’s MY2021 ID.4 pattern — substituting any other character in position 8 and decoding through NHTSA vPIC returns ‘unable to provide information for some of the characters in the VIN’ rather than a different powertrain. On a battery-electric car there is no engine family to fork, so the launch-spec habit of reading position 8 does not transfer. Position 4 is the character that matters, and it carries trim and drive layout together. Confirmed through vPIC by holding the rest of the VIN constant and varying position 4 alone: ‘D’ decodes as 1st Edition, rear-wheel drive; ‘R’ as Pro, rear-wheel drive; ‘K’ and ‘T’ as Pro S, rear-wheel drive; ‘U’ as Pro S, all-wheel drive. That single character is therefore how you confirm single-motor versus dual-motor before you look at a window sticker, and it is worth confirming, because AWD arrived partway through the 2021 model year rather than at launch and the 1st Edition was never built with it. The drive layout also redirects the inspection: a dual-motor car adds a front drive unit that a rear-drive car does not have, so include it in the test drive and the service history. What position 4 does not tell you is battery state of health, which is the real money question on any used EV — check displayed range at a 100 percent charge against the rated figure, and treat the 12V auxiliary battery as a separate item, since it is the most common ID.4 repair and is unrelated to the high-voltage pack. Run the full VIN at nhtsa.gov and confirm every software campaign on this car is closed.
