2013 Kia Optima: what breaks, and at what mileage

What breaks on the 2013 Kia Optima

On the 2013 Kia Optima, the failure owners report most often is other engine problem, and the reports cluster around 98,000 miles. The earliest to appear is other suspension problem, reported by a median of 20,000 miles. Overall it scores 76 out of 100, severe risk for a 2013.

Severe risk for a 2013 — 53rd riskiest of the 284 2013 vehicles we can rate. 1,887 owner reports; fleet size estimated from this year's own recall paperwork.

What breaks on the 2013 Kia Optima

Owners have reported 75 named failure modes on the 2013 Kia Optima, and the three most-reported carry 37% of everything filed.

Other engine problem leads with 444 reports, about 3.4 per 1,000 vehicles and with the middle half of reports between 74k to 128,000 miles.

Other steering problem follows with 159 reports, usually reported between 8k to 74,000 miles.

Other body or interior problem follows with 97 reports, usually reported between 56k to 100,000 miles. 8 of those reports mention a fire.

By system, the reports fall mostly into engine (646), steering (201) and body (158).

At what mileage it happens

1,042 of the reports on the 2013 Kia Optima came with an odometer reading, and half of those were filed before 82,000 miles.

Cumulatively, 29% by 50,000 miles, 63% by 100,000 miles and 89% by 150,000 miles of the dated reports had been filed, with 10 filed above the top of the chart.

The busiest stretch is between 0 and 10,000 miles, which alone holds 10% of the dated reports.

23% of the dated reports were filed below 36,000 miles.

In the order they tend to show up: other suspension problem around 22k, sunroof failure or glass breakage around 25k, other steering problem around 33k and steering rack, gear or tie rod failure around 36k.

Severity, and what it costs

Across the named modes, 65 mention a crash, 157 a fire, 34 an injury and 7 a fatality. 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 4.69, 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 engine problem at $300–$4,000, other steering problem at $350–$2,400, other body or interior problem at $200–$2,000 and other electrical problem at $250–$2,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

38% 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 2013 Kia Optima draws about 15 per 1,000 vehicles, which puts it in the 92nd percentile of complaint rates among 2013 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 128,999 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2013 vehicles, which is what the risk score uses, is far more robust than the rate itself.

What owners wrote

Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.

Other engine problem

Driving under normal conditions on a slow 35mph roadway and noticed optima pulls toward the crown (center) of the road (which is against slope). Drove vehicle on 45mph and 60mph roadway and same situation. Engine was replaced at 3,400 miles due to piston #3 failing. Based on current issues to date, I would not purchase another optima. *tr

3,870 miles NHTSA complaint 968172 filed 2013-03-13

Driving on a city road during normal traffic (4:30pm est) my vehicle began to make large rattling noise from the engine compartment. At first I thought I had picked up somthing on the road, but as I accelerated/deccelerated the noise became louder/softer. I immediatley contacted my kia dealership. After speaking to the service manager he told me to bring the vehicle in next week since that would be the soonest it could be looked at. I informed him that I did'nt think I could even make it home let alone wait a week to bring the vehicle in. He stated I could drop it off, but it would not be looked at until next week. Either way, within 10 miutes of driving a large banging noise went off under the hood, engine oil sprayed throught the engine compartment and I had complete loss of power. Kia roadside assistance towed the vehicle to the dealership where they have informed me that the engine needs to be replaced. The vehicle is less than 2 weeks old and had 600 miles when this occured. I informed the dealership I would not want a vehicle with a replaced engine and they have informed me that is my only option. I will not be purchasing…

600 miles NHTSA complaint 986316 filed 2013-06-14

Other steering problem

New vehicle. The vehicle will not track in a straight line. The vehicle wanders (drifts) left or right. I constantly have to nudge the steering wheel slightly left or slightly right to keep the vehicle somewhere in the middle of the lane. This is a dangerous condition. I no longer take a mug of coffee with me as I drive to work. I have to keep my eyes directly on the road ahead, only glancing briefly in the rear view mirror or side mirrors to check traffic. It also does this at low speeds on residential streets. Help! I am taking it back to the dealer a second time on 11/16. However, I have noticed many complaints on the web for the same vehicle, model and problem. It would seem there is no fix! Has the NHTSA contacted kia about this problem? *tr

25 miles NHTSA complaint 949551 filed 2012-11-15

Tl* the contact owns a 2013 kia optima. The contact stated that the vehicle would drift from side to side when being driven at various speeds. The contact stated that when traveling above 55 MPH, the vehicle would become increasingly difficult to keep the vehicle straight. The vehicle was taken to the dealer where an alignment was performed but did not correct the failure. The vehicle was taken to a second dealer who suggested that they adjust the tire pressure. The tire pressure was adjusted but to no avail. The failure persisted. The failure mileage was 40 and the current mileage was 6,500.

40 miles NHTSA complaint 952502 filed 2012-12-05

Other body or interior problem

This is not a safety problem. The carpet has worn through (threadbare) just in front of the driver seat. I asked the dealer about it and the rep told me it happens with drivers that are six feet tall. The spot that is worn is on a raised surface (cover?) of some sort. A redesign to place a heay duty carpet piece in that part of the carpet or redesign the removable floor mat to cover the spot so it wouldn't wear out the underlying carpet. What to do for repair??? *tr

10,000 miles NHTSA complaint 972115 filed 2013-04-03

Tl* the contact owns a 2013 kia optima. The contact stated that while driving 40 MPH, a noise was emitted from the driver's side window. The vehicle was taken to the dealer for diagnosis where it was stated that the noise was normal. The vehicle was not repaired and the manufacturer was notified. The approximate failure mileage was 20. Updated 09-18-13 *bf updated 09/27/2013 *js

Recalls on the 2013 model year

NHTSA has issued 9 recall campaigns covering the 2013 Kia Optima, affecting an estimated 544,797 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, structure:body:roof and pillars and fuel system, gasoline:delivery:hoses, lines/piping, and fitt. 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.

Risk score against the rest of the 2013 field

Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.

Better and worse years of the same car

Severe risk for a 2013 — 53rd riskiest of the 284 2013 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.

Across the 20 model years of this car that carry enough reports to score, 2005 comes out best at 57 and 2019 worst at 80, with 2013 itself at 76.

If the model year is negotiable, 2005, 2003, 2007, 2006, 2004, 2002, 2010, 2009, 2001, 2008 and 2020 score lower than 2013 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 2011–2016 generation specifically, 2012 is the strongest year at 74 and 2016 the weakest at 77.

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.

Risk score by model year, out of 100

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 2011-2016 generation, 2012 Kia Optima scores best at 74 and 2016 Kia Optima worst at 77.

Where to spend the inspection money

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: other suspension problem from about 2k, other steering problem from about 8k, other driver assistance problem from about 11k and cruise control failure from about 12k.

On a 2013 Kia Optima with more miles than that on it, the useful question to put to a seller or a mechanic is whether other suspension problem 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.

Where these figures stop being useful

1,887 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 1,887 reports, 1,042 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.

Questions this page answers

What are the most common problems with the 2013 Kia Optima?

The most-reported failures are other engine problem (444 reports, median 98,000 miles), other steering problem (159 reports, median 33,000 miles) and other body or interior problem (97 reports, median 72,500 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.

At what mileage do 2013 Kia Optima problems start?

Other suspension problem is the earliest failure mode to show up, with a median reported mileage of 20,000 miles and a quarter of reports before 2,000 miles. Across all failure modes on this year, the median report sits at 82,000 miles.

Is the 2013 Kia Optima reliable?

It scores 76 out of 100 on our risk index, which is severe — 53rd riskiest of the 284 2013 vehicles we can rate. The score is a comparison against other 2013 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 Optima is best?

Within the 2011–2016 generation, 2012 scores best at 74 out of 100 and 2016 worst at 77. 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.
