Splitting the database by vehicle type produces a contradiction that turns out to explain a lot about how complaint data works.
| Type | Recalls per model | Complaints per recall |
|---|---|---|
| Cars | 29.7 | 32.5 |
| Heavy trucks | 37.1 | 0.2 |
| Motorcycles | 2.0 | 1.8 |
| RVs | 14.8 | 0.6 |
Peterbilt: 2,101 recalls, 225 complaints
Across 155 heavy truck models the database holds 5,743 recalls and 959 complaints. Cars produce 41,762 recalls and 1,355,434 complaints.
Individual manufacturers make it starker. Peterbilt has 2,101 recalls and 225 complaints. Autocar has 343 and 7. Mack has 475 and 21.
And 59 truck models carry 10 or more recalls and exactly zero complaints.
Complaints measure owners, not vehicles
The NHTSA complaint system is a form a member of the public fills in. It works because private owners are motivated: they're annoyed, they want a record, they hope something gets done.
A commercial truck is owned by a company. When it breaks, a fleet manager calls the dealer, files a warranty claim, schedules the repair and moves on. Nobody in that chain has a reason to submit a public complaint — the problem is handled through contracts and service agreements that never touch the federal database.
So the complaint record for commercial vehicles is close to blank, while the recall record — which manufacturers file — is fuller than for cars.
Why this matters beyond trucks
It's a warning about reading complaint counts as a quality measure anywhere.
The same effect appears at the top of the market: a low-volume exotic gets few complaints because there are few owners, not because it's reliable. We found 204 models with zero recalls, almost all of them scarce. And 76.1% of all model-years in the database have zero complaints — mostly because nobody owns enough of them to file any.
Complaints are a good signal on mass-market cars owned by individuals. They are close to meaningless everywhere else.
What to do if you're buying a commercial vehicle
Don't read the empty complaint record as reassurance. It reflects who owns these vehicles, not how they hold up.
Do take the recall record seriously. At 37.1 campaigns per model it's higher than for cars, and it comes straight from manufacturers rather than from owners.
Expect unclaimed recalls. These vehicles are registered to companies that dissolve, get sold between businesses, and never see the notification letters. We looked at what they're worth in a seven-year-old Sprinter costs more than a three-year-old sedan.
A VIN check lists open campaigns for a specific vehicle regardless of who owned it before.
Frequently asked questions
Do commercial trucks have more recalls than cars?
Yes — 37.1 recalls per model against 29.7 for cars. But they generate only 0.2 complaints per recall against 32.5 for cars, and 59 truck models have 10 or more recalls with zero complaints.
Why don't commercial trucks generate complaints?
Because complaints are filed by private owners. A fleet manager calls the dealer, files a warranty claim and schedules the repair — none of which touches the federal complaint database.
Does a clean complaint record mean a vehicle is reliable?
Not necessarily. 76.1% of all model-years in the database have zero complaints, mostly because too few people own them to file any. The signal only works on mass-market vehicles owned by individuals.
What should I check on a used commercial vehicle?
The recall record rather than the complaint record — it's higher than for cars and comes from manufacturers directly. Expect unclaimed campaigns, since these vehicles are registered to companies that dissolve or resell them.
