What the known faults on this Kia Optima typically cost to put right at a UK independent garage · use the figures to price risk before you bid, and to justify a reduction when something shows up on inspection.
The single priciest documented job on the 2016–2020 Kia Optima is steering rack / column repair at £400–£1,500. Few cars need every repair listed here · treat £1,520–£7,250 as the full exposure if one arrived with all of them.
Clunking or clicking noise from the steering column due to a worn EPS flexible coupling.
Inspect · With the engine running and the vehicle stationary, rapidly rock the steering wheel left and right. Listen for a distinct plastic or metallic clunk from behind the dashboard.
Infotainment and sensor glitches.
Inspect · Test the screen and features.
Theta II 2.0T/2.4L engine failure (bearing/knock) — recalls and warranty extensions apply.
Inspect · Listen for knock; confirm the knock-sensor recall and any engine replacement.
LED Daytime Running Lights (DRL) flickering, dimming, or failing completely, requiring a costly headlight unit replacement.
Inspect · Turn on the ignition and headlights. Visually inspect both front DRL strips for any flickering, dim patches, or completely dead LED sections.
Hesitation or stuttering under light acceleration caused by soot build-up in the EGR valve on 1.7 CRDi models.
Inspect · Hold the engine revs steadily at 1,500-2,000 rpm whilst stationary. Feel for misfires or rough running, and check the instrument cluster for an illuminated EML.
Electronic Parking Brake (EPB) failing to release fully, leading to binding rear brake calipers.
Inspect · Engage and disengage the EPB switch multiple times. Listen for groaning from the rear wheels and ensure the car rolls freely in neutral without rear-end drag.
Excessive oil consumption.
Inspect · Check oil level and history.
Occasional harsh shifts.
Inspect · Test-drive for smooth engagement.
