Toyota Prius 2016–2022 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes — not generic used-car advice.

1. Check 01

   Run the VIN through Toyota's recall lookup (toyota.com/recall). This generation has several: parking brake cable (2016–2017), engine wire harness (2016–2018), brake booster pump (2019), blank instrument display (2019), and hybrid-shutdown ECU software (2022). All are free fixes — confirm they're done.

2. Check 02

   On 2016–2017 cars, inspect the windshield edge-to-edge for chips and cracks, and ask how many windshields the car has had. Replacements need a Toyota Safety Sense camera recalibration — make sure any past replacement included it.

3. Check 03

   Get under the rear of the car (or on a lift) and look at the catalytic converter: shiny new welds, a rattling heat shield, or an aftermarket converter means it's been stolen once already. A bolted-on cat shield is a plus, not a red flag.

4. Check 04

   Check the 12-volt battery date code (it's under the hood on this generation, not in the trunk) and have it load-tested. A weak 12V causes bizarre electronics behavior and no-starts long before it's obviously dead.

5. Check 05

   Watch the dash on startup: a red triangle, 'Check Hybrid System' message, or persistent low hybrid-battery bars point to an aging HV pack. Note the trim too — lithium-ion and NiMH packs are not interchangeable.

6. Check 06

   On AWD-e cars (2019+), remember the rear motor only works below 43 mph and there's no mechanical connection — test for warning lights rather than expecting to feel it. Check the rear underbody for rust or damage around the motor.

7. Check 07

   On a Prime, charge it fully and confirm real-world EV range is still in the ~20–25 mile ballpark, verify the charging cable is present, and know that 2017–2019 cars seat four, not five.

8. Check 08

   Ask for oil-change records. The engine is tough, but it still wants its 0W-16/0W-20 changed on schedule — and at 100k+ an EGR clean is cheap insurance even though gen-4 clogging is rare.
