Other suspension problem: which cars, and at what mileage

What other suspension problem means here

Complaints are assigned to this mode by matching the owner's own description against a phrase list held in the failure-mode catalogue. The match is made on the text, never on the part number, because owners describe symptoms and not components. It is accurate in bulk and fallible one report at a time.

Where it has to be repaired rather than lived with, $350–$2,000 is the range this site publishes for an independent US shop. It is an editorial estimate, not a figure from NHTSA, and it does not include diagnosis or the labour a dealer would add.

The catalogue classes this mode as moderate, which is what decides its weight in every risk score it contributes to.

Where it starts earliest

Ranked by median reported mileage instead of by rate, the earliest onset is on the 1998 Chevrolet Silverado 1500. Sorted that way the leaders are 1998 Chevrolet Silverado 1500 at 5 miles, 1999 Suzuki Vitara at 6 miles and 1997 Dodge Intrepid at 11 miles.

Early onset and high rate are different findings. A car that reports this failure rarely but at 40,000 miles is a warranty problem; one that reports it often at 140,000 miles is closer to wear. Both belong on the page, and neither answers the other's question.

Which vehicles report it most

The table below ranks 40 model years by reports per 1,000 vehicles built rather than by raw count, which is the only way a ranking like this stays honest: a model that sold two million copies will out-report one that sold thirty thousand even if it is the better car.

At the top, the 2011 Ford F-250 SD shows 14,333 per 1,000 with 43 reports on file.

Ford accounts for 50% of the worst-affected entries on this list, which usually means a shared part, a shared platform, or a shared supplier rather than 20 separate faults.

How to read this page

Nothing here is a defect investigation. It is a count of what owners chose to write to a federal agency about, sorted so that the sales figures do not decide the order. 40,522 reports is a floor: for every owner who filed, some number simply paid the bill and moved on.

If a specific car matters to you, the useful page is the model-year one, where this mode is shown against every other failure reported on the same vehicle. A single failure mode read on its own always looks worse than it is.
