Other powertrain problem on the 2008 BMW X3 Sav

Only 3 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.

When other powertrain problem gets reported

There are 3 reports of other powertrain problem on the 2008 BMW X3 Sav, 3 with a mileage attached. That is too few to place the failure on the odometer with any confidence.

A part like this is normally expected to survive 92,000 miles. It is the 8th most-reported problem on this model year.

The whole distribution

Percentiles of the 3 odometer readings owners gave.
10th25thMedian 75th90th
— — 15,000 miles — —

Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.

What a percentile can and cannot tell you here

These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.

What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.

Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.

What happens, and what it costs

Putting it right typically runs $400–$4,500 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.

The same failure, every year of the BMW X3 Sav

If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote

Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.

My bmw x3 2008 was 'bought back' by bmw after three months of ownership in dec 2008 due to a problem with the transmission. The transmission would not respond when depressing the accelerator at random times. It happened once after pulling away from an ezpass booth - the car just froze and would not accelerate nearly causing an accident. This was so serious that bmw recognized it as a problem but could not fix it despite replacing major transmission parts. They assured me it was not a general problem in x3's so I allowed them to replace the 2008 x3 with a 2009 model. Less than 1000 miles and one month later the 2009 started exhibiting the same problems. This time bmw would not remedy the situation instead denying there was a problem with the car. The matter is currently with my lemon law lawyers and bmw. Here is a link to a blog that shows many bmw x3 owners have the problem - some have had their cars replaced by bmw and others have been ignored. This is a serious safety issue that is being ignored by the manufacturer (similar to the toyota issue). Please investigate before someone gets killed…

1,000 miles NHTSA complaint 758826 filed 2010-02-05

Own a 2008 bmw x3 3.0 si AWD. We had an engine cranking issue and took to vehicle to dealer to have tsb service bulletin number : sib-12-17-07/NHTSA item number : 10028464 performed. Since this was performed, there is very poor throttle response in the normal transmission mode. The transmission will stall to engage with very erratic and hard up and down shifts. The concern is with the delay in throttle response when pulling into traffic, when you give it throttle, it is delayed to respond, presenting a true safety concern. The vehicle has been back to the dealer 2 to 3 times since with no resolution. Bmw north america was contacted and they simply referred me back to the dealer. Spoke with the dealer this week and there is still no resolution as they say they are still waiting on new computer programming; however, they have 3 other x3s in this dealership with the same concern. My fear is that when my wife is pulling into traffic that the vehicle will be delayed in throttle response and a crash may result. Bmw has an issue with this in looking at the bimmerfest.com blog as there are numerous complaints of the same issue on this…

15,000 miles NHTSA complaint 767842 filed 2010-02-27

For nearly the entire time I have owned the vehicle I have had issues with the car jerking and lurching while accelerating in the lower RPM ranges. Of late this has become so bad I am afraid to drive the vehicle. The problem manifests itself mostly between 1,800 and 2,400 RPM with the most severe issues in the 2,200 to 2,400 RPM range. When going from a stop the car will begin to accelerate and when it gets just above 2,000 RPM it begins to jerk and lurch with the tachometer fluctuating wildly. The 4x4 light then comes on and the car completely loses acceleration. This has happened many times while in the middle of a busy intersection. I have been nearly t-boned twice and now fear for my life driving this car. *tr

How far this goes

This page is kept out of search results because 3 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.

Complaints are voluntary, so 3 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.

Questions this page answers

At what mileage does other powertrain problem happen on the 2008 BMW X3 Sav?

Across 3 owner reports that included an odometer reading, half were filed by 15,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other powertrain problem on the 2008 BMW X3 Sav?

3 reports have been filed with NHTSA, about 0.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.

What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
