Other speed control problem on the 2008 Cadillac Cts
4 crashes 2 injuries 6 of the 12 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.
When other speed control problem gets reported
Owners of the 2008 Cadillac Cts report other speed control problem at a median of 30,000 miles. A quarter of the reports come in before 20,000 miles and a quarter after 35,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 8th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 40,000 miles at the ninetieth, a spread of 33,300 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.
80% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 5,000 miles | 17,750 miles | 30,000 miles | 34,250 miles | 38,300 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, 4 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–$2,000 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 8 model years of this car. It shows up earliest on the 2009, at a median of 15,000 miles, and latest on the 2006 at 85,000 miles.
By volume the 2003 carries the most reports, with 16; the 2008 has 12. 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.
Twice ,while driving my wife's 2008 cadillac cts, my foot has wedged both on the accelerator and the brake pedal causing me to proceed forward while attempting to brake. The first @, 6 mos ago ,caused me to proceed into an intersection narrowly being missed by a vehicle coming from my left. The 2nd occurred @ 1 week ago causing me to just miss hitting a car parked in front . My wife had a similar incident @ 6 mos ago while backing out of a driveway. I have reported both incidents to cadillac with no further communication from them. They gave me this site when I requested an agency to report this problem so I might help others avoid being injured. I will not drive my wife's car in the future due to the above incidents and the fear of a more onerous outcome when it happens again. *tr
I was driving my sister-in-law's 2008 cadillac cts home from work one night in december. I came up to the street out of the mall parking lot and put my foot on the brake to slow down. Suddenly, the engine took off and revved up to around 4000rpms, so much I could hardly hold it with the brakes. I put in park and reached down to feel the floor mat to see if it was on the accelerator. It was not. I turned off the car. The next day, I took it to the gm dealer. I don't think they believed me because they could not repeat the condition. They had me leave the car and they said they would look at it. The next day I picked ut up. They said that they had re-programmed the throttle body control unit. I left with the car and proceeded to exit the lot. Just as I got to the street, it took off again, revving to about 4000 rpms or so. I immediately went back and told the dealer what happened. They stared at each other and shrugged their shoulders. They never fixed the problem. I am convinced that this is a software issue in the throttle control system, just like toyota is dealing with. If my wife had been driving this car, she could have been…

While driving at 30 MPH, the contact attempted to brake and noticed that the floor mat was stuck between the brake pedal and accelerator pedal, causing the contact to crash into nearby vehicle. There were no injuries but a police report was filed. The vehicle was taken to an authorized dealership where the contact was informed that the failure could not be duplicated. The failure mileage was approximately 31,000. The current mileage was approximately 34,000.

How far this goes
Complaints are voluntary, so 12 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 other speed control problem happen on the 2008 Cadillac Cts?
Across 10 owner reports that included an odometer reading, half were filed by 30,000 miles. A quarter were filed before 20,000 miles and a quarter after 35,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other speed control problem on the 2008 Cadillac Cts?
12 reports have been filed with NHTSA, about 0.3 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.
