2014 Cadillac Cts: what breaks, and at what mileage

What owners report breaking

Owners have reported 36 named failure modes on the 2014 Cadillac Cts, and the three most-reported carry 52% of everything filed.

Differential or transfer case failure leads with 81 reports, about 2.2 per 1,000 vehicles and with the middle half of reports between 65k to 95,000 miles.

Other powertrain problem follows with 14 reports, median 50,000 miles.

Other electrical problem follows with 8 reports, median 20,000 miles.

By system, the reports fall mostly into drivetrain (86), transmission (17) and engine (17).

How bad it is when it goes

Across the named modes, 7 mention a crash and 6 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.

The average severity weight across every report on this year is 3.95, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.

What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: differential or transfer case failure at $900–$4,200, other powertrain problem at $400–$4,500, other electrical problem at $250–$2,000 and other wheel or tire problem at $200–$1,500. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

63% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures, so more than half of what owners complained about here is expensive.

How often, against how many were built

Scaled by an estimate of how many of these cars exist, the 2014 Cadillac Cts draws about 5.4 per 1,000 vehicles, which puts it in the 85th percentile of complaint rates among 2014 vehicles we can rate.

That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.

The working figure is 36,955 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2014 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Recalls on the 2014 model year

NHTSA has issued 6 recall campaigns covering the 2014 Cadillac Cts, affecting an estimated 115,345 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.

The campaigns cover seats:front assembly:seat heater/cooler, electrical system, seats and electrical system:ignition. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.

One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.

How 2014 compares with the other years

High risk for a 2014 — 107th riskiest of the 270 2014 vehicles we can rate. The comparison is always within the same model year, so an older car is never penalised for having had longer to break.

Across the 16 model years of this car that carry enough reports to score, 2019 comes out best at 58 and 2009 worst at 76, with 2014 itself at 73.

If the model year is negotiable, 2019, 2010, 2003, 2008 and 2012 score lower than 2014 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.

Within the 2014–2016 generation specifically, 2015 is the strongest year at 70 and 2014 the weakest at 73.

What the numbers say to check

The mileages below are where the first quarter of reports for each mode had already been filed, which makes them the point at which a fault is worth looking for rather than the point at which it happens: differential or transfer case failure from about 65k.

On a 2014 Cadillac Cts with more miles than that on it, the useful question to put to a seller or a mechanic is whether differential or transfer case failure has been dealt with, and if so with what parts and at whose expense. A car that has already had the repair is in a different position from one that has not.

Treat it as where to point the inspection, not as a prediction. A well-maintained example can sail past every mileage on this page, and a neglected one can fail well before the first of them.

What this page cannot tell you

198 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.

Of those 198 reports, 108 carried an odometer reading, so the mileages here describe 55% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".

The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.

And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
