Lexus Rx400 H SE CVT (2005)
2005 Lexus Rx400 H SE CVT
CarHunch analysed 138 real MOT records for the 2005 Lexus Rx400 H SE CVT. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2005 Lexus RX400h's 72.6% first-time pass rate trails the UK average by over 7 percentage points, signalling below-average reliability for its age—and that's before accounting for the 35.5% of vehicles that have experienced a dangerous defect, well above the typical threshold and a genuine concern for prospective buyers. These are older hybrid SUVs with genuinely high mileage (median 102,549 miles), yet the real worry isn't the major failures (3.12 per vehicle) but the chronic advisory list averaging 21.3 items, pointing to widespread wear and corrosion across ageing examples.
When evaluating one, budget for labour and parts: Lexus servicing isn't cheap, and hybrid systems add complexity. Before purchase, get a full inspection from a Lexus-familiar mechanic and ask the seller for complete service records—this cohort's poor track record means any gaps in maintenance history should be a red flag.
What to check before buying a 2005 Lexus Rx400 H SE CVT
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 35.5% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
