Hyundai Warranty UK: What the 5-Year Cover Actually Includes (2026)

Quick answer: Hyundai UK offers 5 years unlimited mileage on its standard manufacturer warranty — one of the most generous in the UK market alongside Kia. Plus 8 years on hybrid batteries and 12 years on body corrosion. Covers engine, transmission, electrical major systems, suspension, brakes, and paint. Doesn't cover normal wear items (tyres, clutch, brake pads), damage from misuse, or work done by non-Hyundai-authorised garages. Warranty transfers with the vehicle to subsequent UK owners as long as servicing is maintained at Hyundai dealers.

What the standard 5-year warranty covers

• Engine — internal mechanical failures, oil seals, gaskets
• Transmission — gearbox, transfer case, differential
• Drivetrain — propshafts, driveshafts, CV joints
• Electrical systems — alternator, starter, wiring harnesses, ECUs
• Suspension and steering — major components
• Brakes — calipers, hardware (not pads/discs/wear items)
• Air conditioning — compressor, condenser, system components
• Paint defects — manufacturing defects (3-year limit, typical)
• Corrosion — body panel rust from manufacturing defects (12 years)

What the warranty does NOT cover

• Wear items — brake pads, brake discs, clutch (where applicable), tyres, wiper blades, batteries (12V)
• Service items — oil, filters, spark plugs (handled at scheduled service)
• Cosmetic damage not from manufacturing
• Damage from misuse — track use, off-roading, towing beyond rated capacity, modifications
• Damage from accidents — covered by insurance, not warranty
• Damage from neglect — failure to service, ignoring warning lights
• Work done at non-Hyundai-authorised garages during warranty period

Hybrid and EV battery warranty

Hyundai's hybrid and EV battery warranty is separate from the standard warranty:

• 8 years / 100,000 miles on the high-voltage hybrid battery
• Covers loss of capacity below specified threshold (typically 70-75% of original)
• Replacement battery or pro-rated repair
• Battery State-of-Health (SoH) diagnostic available at Hyundai dealers

Applies to: Ioniq, Kona Hybrid/EV, Tucson Hybrid, Santa Fe Hybrid/PHEV, Bayon Hybrid, Inster EV.

The 12-year body corrosion warranty

Covers body panel rust caused by manufacturing defects — not surface rust from stone chips, scratches, or untreated damage. Conditions:

• Body must have been maintained (regular washing, no untreated damage)
• Any prior damage must have been repaired by Hyundai-approved bodyshops
• Claim within the 12 years of original registration

In practice this is rarely claimed — modern Hyundais have excellent corrosion resistance.

Servicing requirements to maintain warranty

The warranty requires:

• Scheduled service intervals followed (12 months or 10,000 miles standard)
• Service performed by Hyundai main dealer OR Hyundai-approved service centre
• Genuine Hyundai or approved-equivalent parts used
• Service entries recorded in the Hyundai Auto Link app or paper service book

Service at a non-approved independent garage during the warranty period voids cover. After warranty expires, independent service is fine.

Hyundai Plus warranty extension

Hyundai Plus is the manufacturer-backed extended warranty. Extends standard warranty beyond 5 years for an additional cost (typically £200-£500/year depending on model and age). Requires continuous Hyundai main dealer servicing throughout.

Coverage similar to original warranty. Worth considering if you plan to keep the car beyond 5 years.

Transfer to new owner

If you sell your Hyundai during the warranty period:

• Warranty transfers to the new keeper automatically
• The remaining warranty period continues unchanged
• Service history with main dealer servicing is required for continuation
• The new keeper should provide V5C and service history at any future warranty claim

How to claim — step by step

1. Identify the issue (warning light, performance problem, mechanical issue)
2. Book a visit to your nearest Hyundai main dealer (or independent Hyundai-authorised garage)
3. Bring: V5C, service history (paper or app screenshot), original purchase paperwork (where available)
4. Dealer diagnoses the issue. If covered, repair is no-cost to you
5. Loan car provided where work extends beyond 1 day (depends on dealer policy)
6. Repair completion: typical 2-4 weeks

N performance variants

Hyundai N variants (i30 N, Kona N) have the same 5-year warranty but with these caveats:

• Track day use can void specific component cover (transmission, brakes, suspension)
• Aftermarket performance modifications void affected-component cover
• Shorter service intervals; deviation voids warranty

Common Hyundai warranty issues

• GDI engine carbon build-up — Hyundai sometimes covers if reported promptly
• 1.6 T-GDI engine smoke / oil consumption — known issue; warranty may cover engine replacement
• DCT transmission jerky shifts (i30 N, Kona N) — software updates often resolve
• Hybrid battery SoH below threshold — warranty replacement

FAQs

What if I service my Hyundai at an independent during warranty?

Most warranty cover is voided. Switching back to Hyundai main dealer for remaining warranty doesn't restore voided cover.

Is paintwork covered?

Manufacturing defects in paint — yes, typically 3 years. Stone chips, scratches, environmental damage — no.

Does the warranty cover catalytic converters?

Yes for first 5 years, with separate emissions-related warranty extending up to 7 years for some components (typically 8 years/80,000 miles for emissions equipment).

Is breakdown cover included?

Hyundai offers complimentary roadside assistance for the first 1-3 years (depending on model). After that, you'd need a separate breakdown policy.
