Hyundai i30 vs Toyota Corolla: which is the better used buy?

On DVSA MOT records the Toyota Corolla is the more reliable used buy: it passes its first MOT 7.8 percentage points more often than the Hyundai i30 once both are compared against what the national fleet scores at the same age. That comparison covers 23,842 real tests, not a survey.

MOT first-time pass rate

Counted from DVSA’s anonymised MOT test records. “vs age-matched” compares each model against what the national fleet scores at the same age — the only fair better-or-worse number, because an older fleet fails more whatever its build quality.

Model	Pass rate	Age-matched national	Difference	Tests
Hyundai i30	71.2%	75%	-3.8	10,713
Toyota Corolla	84.6%	80.5%	+4	13,129

Hyundai i30

PD, 2017+ · compact family hatch

The PD Hyundai i30 (2017+) is one of the most reliable compact hatches in the UK. The 1.4 T-GDI turbopetrol has documented oil-pressure and injector issues before the 2020 facelift; the diesel 1.6 CRDi is solid. DCT (dual-clutch) on 1.4 T-GDI judders in low-speed traffic. Best-buy: 2020+ 1.6 CRDi or 1.0 T-GDI. Worst: 2018–2019 1.4 T-GDI DCT.

What goes wrong

1.4 T-GDI engine — oil pressure warningmajor
Oil pressure warning light on startup; engine noise at idle; low oil level despite no visible leak
2018–2019 1.4 T-GDI (before ECU calibration update) · ECU update free under warranty; if engine damage occurred: £2,500–£5,000
Check: Dipstick at viewing — check level and colour. Ask if oil pressure warning has ever been triggered. Service history must show Hyundai-stamp oil changes at 6,200 miles or 12-month intervals (whichever comes first). Avoid 1.4 T-GDI without confirmed ECU update.
7-speed DCT judder (1.4 T-GDI)moderate
Shudder when pulling away from a standstill in traffic; hesitation at low speeds; occasional "clunk" engaging Drive from neutral
2017–2019 DCT variants · DCT software update free at Hyundai dealer; fluid change £150–£220; mechatronic fault £800–£1,500
Check: Test drive in heavy stop-start urban conditions — not just an open road. DCT should engage cleanly. Any shudder requires DCT software check and fluid condition inspection.
1.6 CRDi diesel — DPF (short-trip urban)moderate
"DPF regenerating" warning; limp mode; reduced power
All 1.6 CRDi diesel variants · Usage-pattern-driven · £350–£650 forced regen; £1,400–£2,200 DPF replacement
Check: Ask seller about typical journey length. CRDi used exclusively for sub-6 miles school runs is a red flag. Avoid without evidence of regular 30-minute motorway runs.
TPMS sensor faultsminor
Tyre pressure warning despite correct inflation; sensor unresponsive after tyre change
All PD i30 · £80–£130 per sensor
Check: Check TPMS warning light on dash during inspection.

Typical asking price:: £7,000–£20,000 (2017–2023) (note i30 N Performance can exceed this)
Real-world economy:: 1.4 T-GDI: 36–44 mpg. 1.0 T-GDI: 39–47 mpg. 1.6 CRDi: 49–59 mpg
Vehicle tax:: £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).
Best years:: 2020, 2021, 2022, 2023
Years to avoid:: 2018, 2019

Toyota Corolla

E210, 2019+ · compact hybrid hatch and saloon

The E210 Toyota Corolla Hybrid (2019+) is the most reliable car in its class in the UK. The hybrid system is solid to 125,000+ miles. Minor concerns are rear shock corrosion in coastal areas, an inverter coolant pump recall on some examples, and Touch 2 infotainment lag (cosmetic). Best-buy: any year. Worst: none — exceptional consistency.

What goes wrong

Inverter coolant pumpmoderate
"Hybrid system check" warning; reduced EV-only operation
2019–2020 (recall on some VINs) · Free under recall; £450 otherwise
Check: Verify recall completion via VIN with Toyota UK or the gov.uk recall checker.
Rear shock corrosion (coastal areas)minor
Rust around shock mount; advisory on MOT
All E210 in coastal areas (e.g. the west coast, Scotland, the South West) · Time-driven, typically 5+ years · £200–£350
Check: Underbody inspection at viewing — bring a torch.
Touch 2 infotainment lagminor
Slow response to taps; CarPlay reconnect needed
2019–2022 (Touch 2) · No fix — software limitation. Toyota Smart Connect (post-2023) is significantly better.
Check: Use infotainment for 10+ minutes during test drive — assess if you can live with the lag.
Hybrid 12V auxiliary batteryminor
Cars not used regularly may struggle to wake the hybrid system
All E210 · Battery age, typically 4–5 years · £220–£350 battery replacement
Check: Toyota battery health test at Toyota dealer (£20–£30 if not free).

Typical asking price:: £16,000–£28,000 (2019–2024)
Real-world economy:: 59–71 mpg real-world hybrid — best-in-class on UK roads
Vehicle tax:: £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).
