Two in Five Complaints Mention the Dealer. 7,186 Say the Fault Could Not Be Reproduced.

A complaint to the federal database is supposed to describe a defect. A large share of them describe a conversation instead.

Of 1,109,342 complaints, 437,549 mention the dealer. That is 39% — two in every five.

What the owner is reporting, in those cases, is not only that something broke. It is that they took it somewhere and came back with the problem.

The third line is the interesting one. 7,186 owners wrote that the fault was there, they brought the car in, and the technician could not make it happen.

The intermittent fault is the hardest thing in the record

A fault that appears once a fortnight, at a particular temperature, at a particular speed, is genuinely difficult to find in a workshop. Nothing in that sentence requires anyone to be acting in bad faith.

But it puts owner and dealer in an impossible position. The owner knows what happened. The dealer has a car that behaves perfectly. Neither can prove anything, and the car goes home unchanged.

Those cases are heavily weighted toward electrical and speed-control faults — the systems where a fault is a momentary event rather than a broken part somebody can hold up.

The share varies more by brand than you would expect

If mentioning the dealer were simply a function of how often cars break, the share would be roughly constant across brands. It is not.

Thirteen percentage points separate RAM from Subaru. That gap is not a measure of service quality, and it should not be read as one.

It is closer to a measure of how long the argument went on before the owner gave up and wrote to a regulator. A fault fixed on the first visit rarely produces a complaint at all. A fault that survives three visits produces one that reads like a diary.

Warranty is the other half of it

8,452 complaints specifically mention being out of warranty. In most of them the owner is making the same argument: the fault is a design problem shared by thousands of cars, and the date on the paperwork should not decide who pays for it.

That argument has a real basis. A fault that takes years to appear will, by definition, appear after the warranty on many of the cars carrying it. Air bag inflator defects took nine years on average to be formally acknowledged.

What it means for an owner

If a fault is intermittent, the complaint record is on your side more than the service record is. A search for your model and symptom will usually show whether hundreds of other people have described the same thing.

That does not obligate anyone to repair it for free. But a documented pattern is a better opening than a description of something that happened once on a Tuesday, and it costs nothing to check before the appointment.
