Used Vehicle Review: BMW X3, 2004-2010 –

December 2, 2010

The BMW X3 was introduced for the 2004 model year as a smaller alternative to the brand’s original crossover, the X5. When it went on sale, the X3 shared its compact, luxury crossover status with just one other vehicle, the Land Rover Freelander, and it wasn’t until 2007 that it would have another competitor in the Acura RDX. The only other vehicles that might be seen as true competitors were fully-loaded versions of more affordable crossovers like the Ford Escape or Subaru Outback, for just a couple of examples.

By 2009, Audi had joined the fray with its Q5, and the 2010 Mercedes-Benz GLK-Class was available in calendar-year 2009 too.

The original X3 was available with two inline six-cylinders, one being a 2.5-litre (184 hp; 2.5i model) and the other a 3.0-litre (225 hp; 3.0i model), both borrowed from the 3 Series sedan line. In 2007, the engine line-up was revised: the 2.5-litre was dropped, and a 215-hp version of the original 3.0-litre became the base engine, while a 260-hp motor was the upgrade.

The model designations were changed to reflect this, with the base model now known as the 3.0i, and the more powerful version called the 3.0si. For 2009, the base 3.0i model was dropped, and the remaining model renamed as the xDrive30i, and in 2010, an xDrive28i was added, using a less-powerful version of the 30i#8217;s engine.

Initial transmission choices were a six-speed manual that could be optioned to a five-speed automatic with either engine. In 2007, the five-speed auto was dropped in favour of a six-speed unit, and the manual transmission was cut from the option sheet in 2009.

Performance at the pumps has more to do with transmission choice than with what engine you prefer. A 2005 X3 3.0i was rated at 13.8/8.8 L/100 km (city/highway) with the manual transmission. Those figures were nominally higher than a manual-equipped 2.5i model, but choosing the automatic with the larger engine means a seven per cent bump in the city fuel consumption rating.

The penalty is smaller with the lesser engine, and the difference in highway consumption is much less severe.


For 2007 models, with their revised engine line-up and new six-speed auto, fuel consumption is lower, with ratings for all models coming in between 12.2/8.2 and 12.5/8.4 L/100 km (city/highway), regardless of engine or transmission choice.

Consumer Reports gives the X3 a used vehicle reliability rating of average to above-average, depending on model year.

X3 owners posting on a couple of different BMW forums mention incidences where the ABS, brake and four-wheel drive system warning lights all come on at once while the car is being driven. Possible causes range from a bad wheel speed sensor (these work with the anti-lock braking and traction control systems) to a bad sensor in the all-wheel drive transfer case gearbox. Check these threads at and (one and two ) for more information.

An engine cooling system problem noted by Consumer Reports is related, best as I can determine, to many mentions in BMW forums of drivers being alerted to a low coolant level by the car#8217;s on board computer. What#8217;s not clear is whether the X3 is more prone to coolant leaks or faulty coolant level sensors.
