Steering column or shaft failure on the 1997 Chevrolet Corvette
When steering column or shaft failure gets reported
Owners of the 1997 Chevrolet Corvette report steering column or shaft failure at a median of 35,000 miles. A quarter of the reports come in before 25,000 miles and a quarter after 55,000 miles, from 14 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 85,000 miles at the ninetieth, a spread of 62,650 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
57% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 23,000 miles | 23,475 miles | 32,546 miles | 54,344 miles | 85,650 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 $600–$2,500 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 11 model years of this car. It shows up earliest on the 2004, at a median of 30,000 miles, and latest on the 2001 at 50,000 miles.
By volume the 1998 carries the most reports, with 117; the 1997 has 44. 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.
While backing out of my drive the steering column locked up and would not allow the wheel to turn. All I could do is pull straight forward into my garage and turn off the car. Ref. In ea02-031 *cjs
The engine light and the service traction light had come on while traveling. The repair work was made on the pulley, and the balancer. The top pulley looked as if someone began to work on it but didn't finish because the bolts were loose. The consumer had taken the vehicle to another shop and was told that there was a program error. The primary belt/tensioner belt had come off-the tensioner belt was replaced. The steering column locked up, the power steering belt was taken off. The low traction light had come on intermittently while accelerating and making turns. The keyless entry remotes were inoperative and were reprogrammed. The vehicle made a loud popping noise.

How far this goes
Complaints are voluntary, so 44 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 column or shaft failure happen on the 1997 Chevrolet Corvette?
Across 14 owner reports that included an odometer reading, half were filed by 35,000 miles. A quarter were filed before 25,000 miles and a quarter after 55,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is steering column or shaft failure on the 1997 Chevrolet Corvette?
44 reports have been filed with NHTSA, about 4.9 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.
