Transmission failure requiring full replacement
an unusual noise from the transmission that precedes an outright failure
Check engine light: On
This is the most serious issue we found for this generation: one documented case of full transmission failure at 51,000 miles, which began as a "weird noise" that a shop diagnosed as the transmission being about to fail. The repair cost $6,500 — we've widened that to a $5,200–$7,150 range to reflect the normal spread in labor rates and parts sourcing. The owner in this case also dealt with a four-day repair delay and rental car costs during a cross-country trip, which is a useful reminder that transmission failures like this rarely happen at a convenient time. Transmission failures like this commonly trigger a check-engine code before the point of total failure, which is why we've marked the light as typically on. This is distinct from a separate "stuck in gear" symptom that may be covered by an open recall — see the recall notice above.
$5,200 – $7,15051,000 mi
based on a single documented case, in a generation with an unusually thin overall data sample — treat as representative, not a guaranteed figure.

Fuel pump failure
stalling or hard starting, consistent with a failing fuel pump
Check engine light: On
One documented case: a fuel pump failure at 18,510 miles, costing $400 — we've widened that to a $320–$440 range to reflect the normal spread in labor rates and parts sourcing. This case was originally filed under the transmission category in the available data, which appears to be a data-entry quirk rather than an actual transmission connection — it's an engine/fuel-system issue. Fuel pump failures typically trigger a check-engine code (often a fuel-pressure-related one), which is why we've marked the light as typically on.

Battery not holding a charge
the battery won't hold a charge, needing a jump or replacement
Check engine light: Off
One documented case: a battery replacement at 27,000 miles, costing $155 — the likely range is $150 – $170 once labor rates and parts sourcing vary. This is a straightforward electrical wear item, not an engine issue, so it doesn't trigger a check-engine light.

Door locks malfunction, can't open doors
Doors won't unlock or open, sometimes trapping occupants
Check engine light: Off
The most frequently reported problem on this generation: malfunctioning door locks that can prevent doors from opening.
↑ Back to the problem table
Faulty throttle position switch
Hesitation, rough acceleration, or check engine light
Check engine light: On
A faulty throttle position switch is reported on this generation.
↑ Back to the problem table
Software update to correct transmission issues
Harsh or erratic shifting, correctable with a software update
Check engine light: Off
Unlike the full transmission replacement listed above, this is a software-correctable shift-quality issue rather than a catastrophic mechanical failure.

Weak alternator replacement program
Dimming lights, battery not holding a charge, or weak charging
Check engine light: Off
Kia is reported to have issued a new alternator to replace a weak original unit on this generation.

AC compressor clutch failure
Loss of AC cooling performance
Check engine light: Off
This is part of a trio of related Kia problems (AC compressor clutch, transmission software update, and approved-transmission-fluid guidance) reported on 4 Kia nameplates.

No sound from speakers
Radio/speakers produce no sound despite the system otherwise working
Check engine light: Off
Part of a large cross-brand Hyundai/Kia speaker-failure pattern reported on 11+ nameplates.

Crankshaft position sensor damaged if timing belt breaks
No-start or stalling after a timing belt failure
Check engine light: On
A broken timing belt is reported to damage the crankshaft position sensor on this generation.

False intake air temp sensor code
Check engine light with an intake air temperature sensor code, no actual sensor fault
Check engine light: On
A false intake air temperature sensor code is reported, correctable with a PCM software update rather than a parts replacement.
↑ Back to the problem table
Persistent check engine light with repeated cylinder misfires
Persistent check engine light, repeated misfires on cylinders 2 and 3, loss of power
Check engine light: On
A persistent check engine light tied to repeated misfires specifically on cylinders 2 and 3, with an accompanying loss of power, is reported on this generation. Low-to-moderate volume — included given the specificity of the symptom.
↑ Back to the problem table
Excessive oil consumption
Needing to add oil between changes
Check engine light: Off
Excessive oil consumption is reported on this generation.
↑ Back to the problem table
Intermittent stalling not duplicated by dealer
Intermittent stalling or chugging that the dealer couldn't reproduce
Check engine light: Off
A stalling complaint is reported, though the issue reportedly couldn't be duplicated by a dealer.
↑ Back to the problem table
Camshaft position sensor fault
Check engine light tied to a camshaft position sensor that's reportedly hard to locate/access
Check engine light: On
A camshaft position sensor fault is reported, with owners noting the sensor is hard to locate.
↑ Back to the problem table
Loose or clunking steering wheel
Looseness or clunking felt in the steering wheel, tied to a faulty steering coupler
Check engine light: Off
A loose/clunking steering wheel tied to a faulty steering coupler is reported.

Reports for this generation are thinner than most — a sample of 9 repairs — so treat this as a starting point rather than a confident ranking. The most serious issue we found is transmission failure requiring full replacement, which one owner traced back to a "weird noise" a shop diagnosed as the transmission being about to fail — documented at $6,500 (51,000 miles), with a likely range of $5,200–$7,150 once labor rates and parts sourcing vary.
