Steering rack, gear or tie rod failure on the 2008 Chevrolet Impala
When steering rack, gear or tie rod failure gets reported
Owners of the 2008 Chevrolet Impala report steering rack, gear or tie rod failure at a median of 50,000 miles. A quarter of the reports come in before 40,000 miles and a quarter after 70,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 98,000 miles. It is the 26th most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 80,000 miles at the ninetieth, a spread of 54,220 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.
25% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 23,780 miles | 38,975 miles | 52,100 miles | 69,000 miles | 78,000 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 $700–$2,600 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 on other years
The same failure is reported on 17 model years of this car. It shows up earliest on the 2003, at a median of 5,000 miles, and latest on the 2012 at 65,000 miles.
By volume the 2000 carries the most reports, with 63; the 2008 has 8. 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 own a 2008 chevy impala and I have been hearing clicking noises in the steering shaft. I have took my car in to be serviced and they put 2 new front tires on replaced the assist steering shaft and put a 4 wheel alignment on the car because my tires were worn on the outer edge I still hear the same noise when I turn coming out of a parked position and the new tires they put on one was defected and I almost had a major accident on interstate 38 in camden n.j because one of the tires radial belts popped and caused a blow-out which sent me and my husband and 2 kids in a fight for our lives trying to get out of on- coming traffic we had to ride around on a donut in a 2008 for 12 hours until we could find a used tire to come back to richmond virginia 256 miles away from home. I also owned a 2004 chevy impala and upgraded to the 2008 after having my car serviced 5 times for the same thing and low and behold I'm experiencing the same problem click click click................................... *tr
Tl* the contact owns a 2008 chevrolet impala. The contact stated the sidewalls on the tires were wearing prematurely. The vehicle was taken to an authorized dealer and the dealer stated that the rear tie rod was defective. As a result, the brakes, rotors and tires were wearing prematurely. The dealer replaced the tie rod and all of the components which were wearing prematurely, but the failure continued. The failure mileage was 60,000 and the current mileage was 75,000.
Symptoms were noise when steering at low speed, play in steering wheel and vehicle "wandering" when driving in a straight line. Problem was defective intermediate steering shaft. Gm redesigned the intermediate steering shaft in 2008 in response to these very problems. Gm has not issued a recall for this part, but there have been multiple technical services bulletins, including tsb # 01-02-32-0010. The tsb indicates the need for replacing, not lubricating, the part. The tsb states "engineering changes have been made to the service parts available through spo. The service parts for the vehicles listed in this bulletin will no longer require lubrication of the intermediate steering shaft" gm re-engineering the part indicates to me as an owner that they know the original product was defective, but are choosing to replace a defective, potentially dangerous part at the owners expense. This problem is widely documented on gm owner and dealership forums across the internet. This problem is shared by chevrolet impalas, chevrolet monte carlos, buick regals, buick lacrosses, oldsmobile intrigue and pontiac grand prix. All of these vehicles…

How far this goes
Complaints are voluntary, so 8 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 steering rack, gear or tie rod failure happen on the 2008 Chevrolet Impala?
Across 8 owner reports that included an odometer reading, half were filed by 50,000 miles. A quarter were filed before 40,000 miles and a quarter after 70,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is steering rack, gear or tie rod failure on the 2008 Chevrolet Impala?
8 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.
