@CarExamer 9 Views 0 Comments

The Kia Sorento is a well-known family SUV that offers space, comfort and a long manufacturer warranty. But like any used vehicle, it comes with its fair share of issues that buyers should be aware of. In this honest guide, we’ll cover the most common Kia Sorento problems and what you can expect to pay for repairs in the UK. Whether you’re considering a used Sorento or already own one, this article will help you understand the typical faults and their real costs.

1. Engine Problems – Costs Between £2,500 and £5,000

Affected years: Mainly 2011 to 2017
Engine types: 2.4L petrol and 2.2L CRDi diesel

One of the most serious problems reported is engine failure, especially in older models. The 2.4L petrol engine is known for developing worn crankshaft bearings that can lead to knocking noises, loss of oil pressure and eventual seizure.

Symptoms to watch for:

  • Loud knocking from the engine
  • Sudden drop in performance
  • Oil warning light on the dashboard

Typical repair costs:

  • Engine replacement (new): £4,000 to £5,000
  • Rebuild (bottom end bearings and crankshaft): £2,500 to £3,000
  • Used engine with fitting: £2,000 to £3,500

Kia has issued recalls and warranty extensions on some engines, so always check with a dealer before buying.

2. Automatic Gearbox Issues – Up to £3,000

Affected years: 2011 to 2015

The automatic transmission in early Sorentos can develop serious issues with gear slipping, jerking or complete failure. This is more common in higher-mileage models and those with poor service history.

Common symptoms:

  • Delayed gear engagement
  • Jerking when shifting
  • Transmission warning light on

Repair costs:

  • New automatic gearbox: £2,500 to £3,000
  • Reconditioned unit: £1,800 to £2,400
  • Valve body replacement: £700 to £1,200

Fluid flushes may help in mild cases, but more often a rebuild or replacement is needed.

3. Electrical and Infotainment Glitches – £100 to £800

Affected years: 2016 to 2020

Modern Sorentos have advanced electrical systems, but these can develop faults over time. Owners have reported issues with screens freezing, reversing cameras not working and tailgates failing to open or close properly.

Typical causes:

  • Software bugs
  • Faulty wiring or control modules
  • Moisture ingress in connectors

Repair costs:

  • Infotainment software update: £100 to £200
  • Reversing camera replacement: £300 to £500
  • Body Control Module (BCM): £600 to £800

Dealers can often update the software, but hardware faults may require full replacement.

4. Suspension Wear and Noises – £200 to £1,200

All model years affected, especially after 60,000 miles

With UK roads full of potholes, it’s no surprise that Sorento owners often report worn suspension parts. The most common faults include worn anti-roll bar links, control arm bushings and noisy shock absorbers.

Signs of trouble:

  • Clunking when going over bumps
  • Uneven tyre wear
  • Loose handling at speed

Repair costs:

  • Drop links: £150 to £250
  • Control arms: £250 to £400 each
  • Full suspension overhaul: £800 to £1,200

Fixing the suspension early prevents damage to tyres and improves ride comfort.

5. Airbag Warning Light – £100 to £500

Affected years: 2012 to 2018

The airbag light is a common fault and can be caused by anything from a faulty seat sensor to a damaged clock spring in the steering wheel.

Symptoms:

  • Airbag warning light stays on
  • No fault stored when scanned (in some cases)
  • Warning comes and goes

Repair costs:

  • Seat occupancy sensor: £150 to £250
  • Clock spring: £200 to £300
  • Full airbag system diagnosis and fix: £400 to £500

Never ignore this warning light. It could mean the airbags won’t deploy in a crash.

Should You Still Buy a Kia Sorento?

Yes, but with caution. Later models from 2021 onwards are far more reliable, and even older models can be great value if you know what to look for. Service history is critical, and you should always have the car inspected before buying.

Pros:

  • Spacious 7-seat interior
  • Long 7-year warranty from new
  • Good towing capacity and family practicality

Cons:

  • Costly repairs if problems are ignored
  • Some models affected by recalls
  • Older engines have known design weaknesses

Expert Tip Before You Buy

Always get a professional pre-purchase vehicle inspection before buying a used Sorento. Problems like worn bearings, electrical gremlins or gearbox faults are easy to miss if you’re not a mechanic.

Best option in the UK: Use CAREXAMER for your inspection. Their mechanics give a much deeper and more honest report than AA or RAC checks. CAREXAMER inspections are trusted by thousands of UK buyers and reveal hidden faults that most people overlook.

Final Thoughts

The Kia Sorento is a strong SUV with real family appeal, but only if you know what you’re buying. Look out for these common issues, check service history and use a trusted inspection service to avoid costly surprises.
