Ignition switch, key fob or immobilizer failure on the 2008 Chevrolet Corvette

2 crashes 2 injuries 4 of the 7 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.

Only 7 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 ignition switch, key fob or immobilizer failure gets reported

There are 7 reports of ignition switch, key fob or immobilizer failure on the 2008 Chevrolet Corvette, 7 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 85,000 miles. It is the 12th most-reported problem on this model year.

The whole distribution

Percentiles of the 7 odometer readings owners gave.
10th25thMedian 75th90th
— — 59,902 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

Of these reports, 2 a crash and 2 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.

Putting it right typically runs $250–$1,500 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 on other years

The same failure is reported on 6 model years of this car. It shows up earliest on the 2010, at a median of 10,000 miles, and latest on the 2008 at 60,000 miles.

By volume the 2008 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.

Does someone have to die? Our brand new 2008 base model corvette has lost power in the middle of the road, 5 times driving to our home. The 4th time my husband was almost rear ended by a truck! First time we had the car a week. 2nd time the dealer said it was the gas. We use chevron texaco. 4th time the liaison from chevy said that oil was getting into our gas from a bad ignition switch. Doesn't make since. 5th time was same day as 4th time. It drops from 45 to 10 and goes all the way down to 1st gear. The RPM goes up and down. It back fires! We have been taking it to the local chevy dealer in kingman az. The 4th time it happened my husband pulled over but didn't turn off the car, and waited for someone from the dealership to drive up and get in the car for a drive. It was idling up and down for about 15 min then idled fine. After hooking up a computer scanner to the car they started up the hill. They drove 2 miles 45 miles per hour, then it just dropped to 5 miles per hour surging back and forth. Making this the 5th time! Foot was steady on the throttle. Husband was told to hold it to the floor, and then it back fired real loud…

How far this goes

This page is kept out of search results because 7 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 7 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 ignition switch, key fob or immobilizer failure happen on the 2008 Chevrolet Corvette?

Across 7 owner reports that included an odometer reading, half were filed by 60,000 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 ignition switch, key fob or immobilizer failure on the 2008 Chevrolet Corvette?

7 reports have been filed with NHTSA, about 2.0 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.
