I have an immaculately maintained 2018 Infiniti Q70L, but the OCS system began having issues at under 75k miles.

Now the…
The Passenger Occupant Classification System in the passenger seat is showing an airbag code of B00A0-02 on my 2018 Infiniti Q70L . The dealer cannot clear that code. The only solution is to replace the entire seat bottom (leather/foam/all electronics for raising the seat) all integrated. That part number is…

My 2019 q70l has heated steering wheel. When it says "heated" I did know it was going to be this hot. At the same time on my spouse 2020 qx60 it works perfect.

The same model year, different builds
Every complaint carries the first 11 characters of the VIN — plant, year, body and engine. That is a production series, and complaints are spread across them very unevenly.
| Measure | Value |
|---|---|
| Distinct production series | 8 |
| Average complaints per series | 1 |
| Worst single series | 1 complaints |
| Average age at failure | 6.6 years |
A model average of 1 hides a worst series at 1. Enter a VIN above to see the numbers for that exact build instead of the model as a whole.

How we count
Every figure here comes from complaints owners filed with NHTSA — 1,100,006 of them, covering 1,982 models built between 1981 and 2026.
A complaint is an unverified report: someone wrote down what happened to their car. It is not a confirmed defect and not a recall. What makes the volume useful is the pattern — when thousands of owners of the same build describe the same failure, that is a signal no marketing brochure will give you.
Two things we do that the source does not. First, we compute the age of the car at the moment of failure from the incident date and the model year. Second, we group complaints by the first 11 characters of the VIN — the production series — so a bad plant run does not disappear into a model-wide average.
