2018 BMW X3
This year drew an ordinary 72 complaints for a BMW X3 — the model's median is 128. What they were about is the unusual part: 9.7% of them mention headlights, against 1.7% across the other years of this generation.
First year of a new generation. The BMW X3 was redesigned for 2018. A first year carries problems nobody has found yet, and they are found by the people who buy it — which is worth knowing before you become one of them.
NHTSA opened a defect investigation into this model year.

Words owners used for the same problem are counted together, so a fault written four different ways is measured once. Grouped by which complaints they appear in, not by a list anyone wrote in advance.
What owners wrote
Front headlights were replaced under warranty after daytime running lights both stopped working in Oct. 2021. Similar problem now on 9/4/25 approximately 4 years later, and BMW is leaving me to foot the bill on a barely 7 year old vehicle, forcing me to have 3…

How this was worked out
Every year of the BMW X3 was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.
This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
