Kestrel Take
Two complaints on the whole model year, both about airbags, and no recall campaigns at all. That is a record we cannot build a reliability opinion on, and it should not be read as one: two filings means two people filed. The useful facts are that the airbag-software recall which covered the 2014 through 2018 cars does not reach a 2021, so an SRS lamp on this year is your bill rather than a dealer's; and that the headline ten-year powertrain warranty Mitsubishi advertises is written for the original buyer — a second owner gets much less, so ask a dealer what this specific VIN still carries before you let it price the car. Drive the transmission hard and check the dash lamps; the rest you are buying on faith.
What we checked
Checked against public records, 2026-09-25
NHTSA holds 2 owner complaints for the 2021 Mitsubishi Mirage, and no recall campaigns.
That is too small a record to read a pattern from, so we are not going to pretend otherwise — with numbers this low one owner moves the percentage by a lot. What has been filed is grouped under airbags (2). Treat those as things to look at, not as the vehicle's known weaknesses. A thin file usually means few of these were sold or few owners filed. It is not evidence the vehicle is trouble-free, and the issues below are our own research rather than a reading of this record.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
Known Issues for the 2021 Mitsubishi Mirage
Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.
Both of this year's filings are airbag-related and one of them is directly checkable: an owner whose airbag lamp has been lit for three years, ruled out wiring and a fuse, and was quoted enough to put them off fixing it — which means the bags will not fire. On a car this age the usual causes are the clock spring behind the steering wheel, a passenger seat occupant sensor, or a connector under a front seat that got kicked loose. Turn the key and watch: the SRS lamp should light for a few seconds and go out. Lit, flashing, or never lighting at all are all failures, and the last one usually means somebody removed the bulb.
Repair cost (estimate): $250–$1,100 depending on whether it is a connector, the clock spring or the control module
Source: NHTSA complaints filed under airbags (2).
No transmission complaints were filed on this model year, which tells you how many owners wrote to NHTSA and nothing about the gearbox. The Mirage's continuously variable transmission is still the component that decides whether a cheap car stays cheap: it is swapped as an assembly, and the bill lands above what a five-year-old Mirage is worth. The test is free and takes four minutes. Accelerate gently from rest three times looking for a shudder through the floor, then hold 45 mph on a level road and listen for a whine that climbs and falls with the engine rather than with road speed.
Repair cost (estimate): $3,000–$4,500 for a replacement unit; $150–$250 for the fluid service that is supposed to prevent it — about 38% of what this car is typically worth

Walk-Away Red Flags
- ✗SRS lamp lit on the dash, flashing, or missing entirely at key-on
- ✗Shudder through the floor as you pull away gently from a stop
- ✗Transmission whine that rises with engine revs while road speed stays flat
- ✗Seller who describes the ten-year warranty as though it transfers to you
Good Signs
- ✓Dash lamps that all illuminate at key-on and then go out in sequence
- ✓A written answer from a Mitsubishi dealer on what this VIN's warranty still covers
- ✓CVT fluid service on a receipt with the odometer reading on it
- ✓Steady, quiet cruise at 45 mph with the engine settling at one steady speed
