Kestrel Take

Five complaints across the whole model year, each one sitting alone in its own category, and two of the five are the same car filed twice. That is not a verdict on the car — it is a record too small to support one, and on a low-volume sports car it mostly reflects how few owners file anything. Read the page for what to check, not for reassurance we have not earned. The one complaint with teeth is an owner who stalled at various speeds with the traction light on and was told the engine needed replacing; the one with a lesson is an owner who got a recall notice and then waited past reasonable for the part. Our copy of the record lists no recall campaigns for this year, which is exactly why you should run the VIN through NHTSA's own lookup rather than trust any summary, this one included. Mechanically this is a simple, durable little car. Most of the money you can lose on one is in rust, water and a tired roof.

What we checked

Checked against public records, 2026-09-25

NHTSA holds 5 owner complaints for the 2012 Mazda MX-5 Miata, 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 the body and structure (1), stability control (1), the engine (1). 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 2012 Mazda MX-5 Miata

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

One owner stalled at speed and was told the engine needed replacingMedium

The same complaint appears twice in the cluster table, once under stability control and once under engine, because the traction control light came on when the car stalled. The owner reports stalling at various speeds, being able to restart, and then a dealer diagnosing a full engine replacement, which was never carried out. One report is not a defect and nothing has been published about a cause, so we are not going to call this a known failure of the 2012 — but a stall at speed is the kind of thing you check for rather than hope about. Drive the car long enough to get it fully warm, use the whole rev range, and treat any stumble, any warning light that flickers, or any hesitation returning to idle as a reason to get a scan before you buy.

Repair cost (estimate): $2,800–$7,500 for a used or rebuilt engine fitted, if it ever came to that — around 58% of what this car is typically worth

An owner left waiting for recall parts — run the VIN yourselfMedium

The single complaint in this cluster is not a breakage at all. It is an owner reporting in 2017 that they had received a safety recall notification for the car and the part needed to carry out the repair was simply not available, with the wait stretching past anything reasonable. We are deliberately not naming a campaign number, because the recall list we hold for this model year is empty and we will not print a number we cannot stand behind. What that inconsistency should tell a buyer is to spend two minutes doing it properly: put the seventeen-character VIN into NHTSA's own recall lookup while you are standing at the car, and ask the seller for paperwork for anything it returns as open.

Repair cost: $0 with the recall — verify it was performed

Tired soft top: fabric, rear window seam and a latch that needs forcingMedium

Not in the record for this year, but it is the part of a fourteen-year-old convertible you are most likely to be buying a problem with. Work the roof by hand several times from the driver's seat: the single centre latch should release and lock with firm, even pressure rather than a fight, and the top should drop into its well and sit flush. Then look closely along the seam where the rear window meets the fabric, at the folds behind the seats, and at the top of the windscreen frame where the seal presses. Cracked stitching, a crazed or hazed rear window, or a seal that has gone hard and shiny all mean water will find its way in, and a replacement top fitted is real money.

Repair cost (estimate): $600–$2,200 for a replacement soft top fitted

Corrosion in the boot floor, under the roof well and around the rear subframeMedium

An age issue rather than a model-year finding, and the thing that separates a bargain from a money pit on a car of this vintage. Water that gets past a tired roof does not stay in the cabin; it runs to the lowest points, which on this car means the boot floor, the spare wheel well and the metal beneath the folded roof. Take a torch, lift the boot carpet and the spare, and look at the seams and the drain grommets. Then get underneath and look at the rear subframe mounting points and the fuel tank straps. A light orange bloom on a subframe is normal in any salted state; flaking that comes away under a thumbnail, or a seam that has swollen and split the paint, is structural and worth walking away from.

Repair cost (estimate): $400–$3,500 from rust treatment up to welded floor or subframe mount repair — about 27% of what this car is typically worth

Walk-Away Red Flags

✗Any stumble, hesitation or warning light flicker once the car is fully warm
✗Open recalls returned when you put the VIN into NHTSA's lookup at the car
✗Centre roof latch that needs forcing, or a top that will not sit flush when stowed
✗Crazed rear window or cracked stitching along the soft top seams
✗Flaking rust in the boot floor, spare well or around the rear subframe mounts

Good Signs

✓A clean diagnostic scan taken while the engine is fully warm
✓VIN lookup returning every campaign as completed, with paperwork to match
✓Soft top latching and stowing cleanly by hand from the driver's seat
✓Clear, uncrazed rear window with sound stitching along the seams
✓Dry, solid boot floor and spare well with the drain grommets clear
