Manufacturer file
What the Infiniti records can tell us
The Infiniti file currently stops at 6 nameplates: Q50, QX50, QX60, QX80, Q60, QX55. Those 55 model-year entries contain 1,137 owner complaints. The missing denominator matters because these records do not say how many vehicles were on the road.
Engine appears most often in the component tags, with 256 mentions. A single complaint may carry several tags. I use the total as a prompt to read that system's contract terms, not as odds that a repair will happen.
Across the same model years, NHTSA records show 81 recall campaigns and 5,500 manufacturer communications. Recall repairs are handled separately from a paid service contract, while communications include far more than defects.
