Every model year has a leading complaint component. Comparing prices against the class-and-year average shows which ones the market punishes.
| Leading complaint | Relative price | Listings |
|---|---|---|
| Power train | 0.860 | 12,934 |
| Engine | 0.884 | 20,616 |
| Steering | 0.940 | 6,970 |
| Electrical | 0.942 | 14,223 |
| Airbags | 0.993 | 11,031 |
| Service brakes | 1.039 | 4,698 |
Twenty-one percent between the top and bottom
A model year known for transmission complaints sells 14% below its segment. One known for brake complaints sells 4% above.
Line that up against what each failure means and the logic is unmistakable: the market prices the repair bill, not the risk.
A transmission is $3,000–7,000 and often terminal on an older car. An engine is worse. Brakes are a few hundred dollars and a routine job — so a reputation for brake complaints costs nothing, because everyone expects to replace brakes anyway.
Airbags at 0.993 is the striking one
Steering sits at 0.940 despite carrying the highest average complaint volume of any category — 1,108 per model year. Airbags sit at 0.993, essentially no discount at all.
These are the two components most directly connected to whether a crash injures you. The market charges more attention to a gearbox.
The explanation is the same as the repair-cost logic: an airbag defect is fixed free under recall, so it costs the buyer nothing in cash. It only costs them in the crash they haven't had yet, and markets don't price that.
What to do with it
The discount tells you what to inspect, not what's dangerous. A 14% cheaper transmission-complaint model year is priced for a risk you can partly verify — fluid condition, shift quality, service records.
The absence of a discount tells you nothing is priced in. On an airbag or steering model year, the market has given you no compensation for the issue, so the check is entirely on you.
Read the component before the count. We found the number of recall campaigns has no effect on price whatsoever — it's what broke that matters.
Check whether the specific car was repaired. Free at any age, no mileage cap. A VIN check lists open campaigns for that vehicle, and we found the airbag inflator takes 9.2 years to even be announced — so a clean report on a recent car isn't the end of it.
Frequently asked questions
Which car problems reduce resale value most?
Power train and engine. Model years whose leading complaint is the transmission price at 0.860 of their class-and-year average and engine at 0.884 — against 0.993 for airbags and 1.039 for brakes.
Why don't airbag problems affect price?
Because the repair is free under recall, so it costs a buyer nothing in cash. The market prices repair bills rather than risk — a transmission is $3,000–7,000 and often terminal, while an airbag campaign is a free dealer visit.
Why do brake complaints not lower prices?
Brakes sit at 1.039, slightly above average. They're a few hundred dollars and a routine job that every owner expects to face, so a reputation for brake complaints carries no penalty.
What should I check on a car with a known defect reputation?
If the market discounted it, the risk is partly priced in and partly verifiable — check fluid condition, shift quality and service records. If it didn't discount, you've been given no compensation and the check is entirely yours.

2,964 Complaints Come From Leased Cars. They Are Filed Earlier Than Anyone Else's.
Ownership changes what people report. Somebody who will hand the car back in two years has no resale value to protect and no repair bill to face, and it shows in the record.
62,142 Complaints State the Exact Mileage. 19,999 Mention the Warranty in the Same Breath.
Nobody asks for the mileage. A sixth of complaints supply it anyway, usually to the exact thousand, because the number is doing a job in the argument the owner is making.
1,372 Owners Filed a Complaint and Traded the Car In. 1,027 Said They Would Never Buy the Brand Again.
There is a moment when a fault stops being a repair problem and becomes a resale problem. A few thousand complaints record exactly that moment, and what it cost the person who reached it.
