2006 BMW 325i Caution
A smooth inline-six rear-drive sport sedan that is rewarding to drive and structurally safe, but the early E90 carries real cooling-system and electrical risk and BMW-level running costs, a good buy only with maintenance records and a repair budget.
- Front passenger occupancy sensor and airbag faults disabling the passenger airbag, plus the model-wide Takata inflator recall, the largest single complaint category for this year.
- Electric water pump and cooling-system failure causing sudden overheating; the belt-less electric pump is a known failure mode on the N52 engine and early 2006 pumps were especially trouble-prone, often around 80,000-120,000 miles.
- Electrical-system faults including blower/PCV-related under-hood electrical smoke and fire reports, and adaptive xenon headlight wiring insulation breaking down.
