What happens when these parts fail
Across the named modes, 2 a fire. 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 3.66, 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: other electrical problem at $250–$2,000, other engine problem at $300–$4,000, other visibility problem at $150–$1,400 and sunroof failure or glass breakage at $700–$4,500. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
25% 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.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2015 Kia Cadenza draws about 1.9 per 1,000 vehicles, which puts it in the 80th percentile of complaint rates among 2015 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 33,272 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2015 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Other electrical problem
Tl* the contact owned a 2015 kia cadenza. While the vehicle was being operated, the front seat passenger noticed smoke and a burning odor coming from the air vents. The failure occurred without warning. The contact pulled the vehicle over to the side of the road and exited before the vehicle caught fire. The fire department extinguished the fire. The vehicle was towed to a salvage yard and was deemed destroyed. A police report was filed. The manufacturer was not notified of the failure. There were no injuries. The failure mileage was approximately 13,000.
While driving home my vehicle began to smoke and leave fumes within the car. I pulled the vehicle immediately to inspect to find that my kickplate was on fire from below the kickplate. I pulled the panel off and doused out the flame. Now with the vehicle home I do not feel safe driving this vehicle knowing something like this is even remotely possible.
Other engine problem
Tl* the contact owns a 2015 kia cadenza. While driving 30 MPH, the vehicle seized without warning. The vehicle would not immediately restart. The contact waited approximately two minutes and the vehicle restarted and resumed normal operation. The vehicle was taken to rick case kia (14500 w sunrise blvd, sunrise, fl 33323, (954) 715-7580) to be diagnosed, but the failure could not be duplicated. The vehicle was not repaired and the failure recurred. The manufacturer was not made aware of the failure. The failure mileage was approximately 39,000.
Other visibility problem
The contact owns a 2015 Kia Cadenza. The contact stated that the front windshield was loose and could be pushed out. The vehicle was taken to the local dealer but, vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA. The failure mileage was approximately 51,000.
The contact owns a 2015 Kia Cadenza. The contact stated that while at a stoplight, he became aware that the windshield was not properly secured. The contact had not taken the vehicle to a dealer to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The contact referenced NHTSA Campaign Number: 22V158000 (Visibility) as a possible solution to the failure. The failure mileage was 52,304.
Recalls on the 2015 model year
NHTSA has issued 2 recall campaigns covering the 2015 Kia Cadenza, affecting an estimated 43,392 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 service brakes, hydraulic:antilock/traction control/electron and visibility:windshield. 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.
Recalls also distort complaint counts. Publicity about a campaign reminds owners that complaining is possible, so reports for a recalled component often spike after the recall rather than before it.

How it ranks in the 2015 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.
- Left fewer and less serious reports
- Right more, or worse
- Marker this vehicle
How 2015 compares with the other years
High risk for a 2015 — 264th riskiest of the 273 2015 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 4 model years of this car that carry enough reports to score, 2016 comes out best at 62 and 2017 worst at 71, with 2015 itself at 62.
No other year of this model scores meaningfully better than 2015, so if this generation is what you want, the year is not the lever.
Within the 2014–2020 generation specifically, 2016 is the strongest year at 62 and 2017 the weakest at 71.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2014-2020 generation, 2016 Kia Cadenza scores best at 62 and 2017 Kia Cadenza worst at 71.
What this page cannot tell you
64 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 64 reports, 17 carried an odometer reading, so the mileages here describe 27% 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".
Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.
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.
Questions this page answers
What are the most common problems with the 2015 Kia Cadenza?
The most-reported failures are other electrical problem (9 reports, median 65,000 miles), other engine problem (7 reports, median 40,000 miles) and other visibility problem (6 reports, median 80,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Is the 2015 Kia Cadenza reliable?
It scores 62 out of 100 on our risk index, which is high — 264th riskiest of the 273 2015 vehicles we can rate. The score is a comparison against other 2015 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.
Which year of the Kia Cadenza is best?
Within the 2014–2020 generation, 2016 scores best at 62 out of 100 and 2017 worst at 71. Same body, same engines, different luck.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
