Timing chain, belt or tensioner failure on the 2009 Dodge Charger
Only 5 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 timing chain, belt or tensioner failure gets reported
There are 5 reports of timing chain, belt or tensioner failure on the 2009 Dodge Charger, 5 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 120,000 miles. It is the 12th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 108,000 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 $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 6 model years of this car. It shows up earliest on the 2013, at a median of 20,000 miles, and latest on the 2008 at 110,000 miles.
By volume the 2012 carries the most reports, with 11; the 2009 has 5. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
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.
I purchased this vehicle used in september 2010. The vehicle had a clean car fax report when I bought the vehicle. I drove the vehicle to work on saturday and back home saturday evening and parked the car in the driveway. When I went to start the car on monday to take my kids to school the car did not start. I had the car towed to an independent mechanic assuming it must have been the starter. To my dismay the mechanic told me I needed a complete valve job for $2,000.00 he told me to take the car to the dealer to see if the car was under warranty for engine failure cause it is no way a 2009 should need a this type of work this soon. He charged me $84.00 for his inspection fee and diagnosis. I had the car towed to jeep /chrysler dodge dealership in ontario california where they told me the same diagnosis except it would cost any where from $2,000.00- $4500.00 for the repair. The dealer charged a fee of $384.00 just to come up with the exact same diagnosis the independent mechanic previously told me for a fee of $84.00. I have contacted chryslers corporate office 12/07/2011 and expect a call back within 24 hours. To add insult to…
The problem is with the 2.7 timing chain and engine. Chrysler had issues with this problem and had filed for bankruptcy. There was a class action regarding this issue. However, chrysler corporation still exists and the customers with the problem still have the same engine issues. There should be a recall for the 2.7 engine.

How far this goes
This page is kept out of search results because 5 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 5 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 Dodge Charger?
Across 5 owner reports that included an odometer reading, half were filed by 110,000 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 timing chain, belt or tensioner failure on the 2009 Dodge Charger?
5 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.
