When timing chain, belt or tensioner failure gets reported

Owners of the 2009 Volkswagen Tiguan report timing chain, belt or tensioner failure at a median of 92,500 miles. A quarter of the reports come in before 85,000 miles and a quarter after 110,000 miles, from 44 reports that carried an odometer reading.

A part like this is normally expected to survive 120,000 miles. It is the 1st most-reported problem on this model year.

The mileage distribution

The reported range runs from 67,500 miles at the tenth percentile to 120,000 miles at the ninetieth, a spread of 53,042 miles across the middle 80% of reports.

A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.

0% of the dated reports were filed under 36,000 miles.

The whole distribution

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 $1,200–$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.

This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.

The same failure on other years

The same failure is reported on 9 model years of this car. It shows up earliest on the 2017, at a median of 35,000 miles, and latest on the 2021 at 200,000 miles.

By volume the 2009 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.

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.

Taking off after getting fuel car start to idle rough when slowing down. Drove directly to dealership less than a mile where the car barely made it into the service area and check engine light came on. Timing chain broke and blew engine. Vehicle has been perfectly maintained by dealer. It appears to be a recurring problem based on internet research. Fortunately, I was not driving on the interstate as normal at that time of day. *tr

104,000 miles NHTSA complaint 993313 filed 2013-07-11

For a week, there was a rattling sound when I started my car that usually stopped after a few seconds of running. On 04/05/14, I heard the rattling sound the entire time when driving. When I stopped, my vehicle cutoff and would not restart. The vehicle was towed to repair shop where the mechanic told me there was no compression in the engine. He later explained the timing chain tensioner broke which caused valves in the engine to bend. Researching the internet, I noticed the same exact diagnosis was given to several other consumers of the same year, make and model. Some of whom had the misfortune of having their vehicles cutoff on the highway. *tr

How far this goes

Complaints are voluntary, so 49 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 timing chain, belt or tensioner failure happen on the 2009 Volkswagen Tiguan?

Across 44 owner reports that included an odometer reading, half were filed by 92,500 miles. A quarter were filed before 85,000 miles and a quarter after 110,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is timing chain, belt or tensioner failure on the 2009 Volkswagen Tiguan?

49 reports have been filed with NHTSA, about 3.9 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.
