Jaguar I-Pace MOT Failures: Common Issues & Parts Guide (X590, 2018–2025)

The Jaguar I-Pace was a genuine game-changer — the first premium all-electric SUV, beating the Tesla Model X to the European market and winning 2019 World Car of the Year. With dual electric motors producing 400hp and 696Nm, a 90kWh battery giving a real-world range of around 230 miles, and the trademark Jaguar driving dynamics, it proved that EVs could be exciting. With the earliest cars now 8 years old and 18,018 MOT tests recorded in 2024, the I-Pace provides a fascinating first look at how a premium EV ages in the real world.

I-Pace MOT Pass Rate

The I-Pace holds a remarkable 93.2% MOT pass rate — 16.5 percentage points above the UK average of 76.7%. That's the highest pass rate of any Jaguar we've analysed — edging out the F-Type's 91.9%. Only the Range Rover L460 (97.5% from a small early sample of 204 tests) scores higher across the wider JLR range. The absence of an internal combustion engine, exhaust system, and traditional drivetrain eliminates entire failure categories.

The 2020 model year is the sweet spot at 94.0% — benefiting from early production improvements. The median mileage at MOT is just 32,455 miles, reflecting typical EV usage patterns. With only 1,751 failure items from 18,018 tests, the I-Pace averages just 0.10 failures per test — the lowest of any JLR model with a substantial test volume. When an I-Pace does fail, it's almost always one single item.

1. Tyres & Wheels — A Massive 62.3% of All Failures

Tyres and wheels account for an extraordinary 62.3% of all failure items (1,091 items). This is by far the highest tyre share of any vehicle we've analysed — and it tells the EV tyre story in stark terms.

What Fails

• Tyre seriously damaged — 646 failures (the #1 item — 36.9% of ALL failures)
• Tyre cords visible or damaged — 231 failures
• Tyre tread depth non-compliant — 133 failures
• Tyre lump, bulge or tear — 21 failures
• TPMS malfunctioning — 14 failures
• Wheel fracture — 8 failures

The tyre damage count at 646 is astonishing — 1 in 28 I-Paces fails on seriously damaged tyres alone. The I-Pace weighs 2,208 kg (nearly 200 kg more than an equivalent ICE car) and delivers 696Nm of instant torque to all four wheels. That combination shreds tyres — particularly the rears on aggressive drivers — and the low-profile 20" and 22" options are extremely susceptible to pothole and kerb damage.

At just 32,000 miles median mileage, these aren't high-mileage wear-outs — this is premature damage from the weight and torque characteristics of the EV powertrain.

What You Need

Tip: EV-specific tyres are not optional — the I-Pace needs tyres rated for its weight and torque. Standard tyres wear significantly faster and provide less grip. Check tyre condition at every service, and budget for more frequent replacements than you'd expect on a car with this mileage. The 20" wheels are more practical than the 22" for UK roads.

2. Suspension — 11.1% of Failures

Suspension accounts for 11.1% of failure items (195 items) — low overall, but with a notable standout.

What Fails

• Steering ball joint with excessive wear — 136 failures (the #3 individual item — 7.8% of all failures)
• Steering rack gaiter deteriorated — 36 failures
• Suspension pin, bush or joint excessively worn — 9 failures

The steering ball joint count at 136 is strikingly high relative to the I-Pace's age and mileage — 1 in 133 cars. This appears to be a model-specific weakness, likely related to the weight of the vehicle and the forces transmitted through the front suspension under regenerative braking. Conventional suspension wear (bushes, joints) is minimal at this age.

What You Need

3. Lamps & Lighting — 8.5% of Failures

Lighting accounts for 8.5% of failure items (148 items).

What Fails

• Number plate does not conform — 83 failures (the #5 individual item)
• Headlamp aim outside limits — 57 failures
• SRS (airbag) MIL malfunction — 37 failures
• Headlamp cleaning device inoperative — 21 failures
• Direction indicator inoperative — 11 failures

The number plate non-conformity at 83 is high — likely aftermarket show plates, as with the F-Type. The SRS warning light at 37 is notable on a car this young — typically a seat occupancy sensor or wiring fault.

What You Need

Tip: The headlamp washers must work on the I-Pace's LED headlamp system — check before the MOT. And swap any aftermarket number plates back to BS AU 145e compliant ones before the test.

4. Visibility — 5.7% of Failures

What Fails

• Wiper blade not clearing windscreen — 63 failures
• Windscreen washers non-functional — 18 failures

What You Need

5. Brakes — 3.1% of Failures

Brakes account for just 3.1% of failure items (55 items) — the lowest brake failure rate of any vehicle we've analysed. The I-Pace's regenerative braking does most of the deceleration work, so the friction brakes see dramatically less use than on an ICE car.

What Fails

• Brake pedal anti-slip provision worn — 20 failures (an unusual item — the rubber pedal pad wears smooth)
• Brake performance unable to be tested — 6 failures
• Brake imbalance — 6 failures

The near-absence of pad and disc wear failures is remarkable — regenerative braking genuinely reduces friction brake wear to a fraction of normal. The brake pedal pad wearing smooth at 20 failures is an oddity unique to the I-Pace in our data.

What You Need

Tip: While regenerative braking saves the pads, the discs can corrode from inactivity. If the car is driven gently and the regen does most of the work, the friction brakes may not generate enough heat to clear surface corrosion. Use the friction brakes firmly at least once per journey to keep the disc surfaces clean.

6. Emissions & Exhaust — 0.3% of Failures

Virtually zero — just 5 failure items in the entire dataset. The I-Pace has no engine, no exhaust, no catalytic converter, no DPF, no EGR valve, and no emissions to test. This entire failure category — which accounts for 2–6% of failures on every ICE Jaguar — simply doesn't exist on the I-Pace.

Beyond the MOT: Major I-Pace Faults That Drive Workshop Visits

Battery Degradation & Range Loss

The I-Pace's 90kWh battery degrades over time — owners typically report 5–10% range loss over the first 50,000 miles, with the rate slowing thereafter. Jaguar warranties the battery to 70% capacity over 8 years / 100,000 miles. Rapid charging frequently and charging to 100% regularly accelerates degradation.

12V Auxiliary Battery Drain

Like all EVs, the I-Pace has a conventional 12V battery for the ancillary systems. This drains if the car sits unused for more than a couple of weeks, causing the car to refuse to start (even with a full main battery). A trickle charger on the 12V battery is essential for cars not driven regularly.

Infotainment & Software Issues

The Pivi Pro infotainment system can be sluggish and crash. Over-the-air (OTA) updates have improved reliability, but early cars on older software versions may need a dealer visit for a manual update.

Heat Pump Failure (2021+ Models)

The 2021 model year added a heat pump for cabin heating efficiency. These can fail, reverting to resistive heating — which dramatically reduces range in winter. A failed heat pump doesn't trigger an MOT failure but is a significant ownership issue.

Door Handle Mechanism

The I-Pace uses flush-fitting electric door handles. The release mechanism can fail, leaving the door impossible to open from outside. The handle mechanism is a sealed unit and requires complete replacement.

Brake Disc Corrosion

Regenerative braking means the friction brakes are rarely used hard enough to keep the disc surfaces clean. Heavy surface corrosion builds up, causing brake judder when the friction brakes are eventually used. Regular firm braking is the prevention.

Suspension Air Spring Leaks (Air Suspension Models)

I-Paces with the optional air suspension can develop air spring leaks — the same issue that affects other air-sprung JLR models. A slow leak causes the car to sit low on one corner after standing overnight.

I-Pace MOT Failure Summary — At a Glance

The EV Advantage: I-Pace vs the ICE Jaguars

The I-Pace eliminates entire failure categories — brakes barely wear, emissions don't exist, and the aluminium body doesn't corrode. The trade-off is tyres: the combination of EV weight and instant torque creates the highest tyre failure rate of any Jaguar. When your car's only real MOT weakness is tyres, that's a very good position to be in.

Keeping Your Jaguar I-Pace on the Road

The I-Pace is the easiest Jaguar to keep on the road — its 93.2% pass rate speaks for itself. No engine oil to change, no timing chains to worry about, no exhaust to corrode, no DPF to clog. The MOT story is almost entirely about tyres (62.3% of failures) — keep them in good condition and you'll pass.

The real ownership costs are tyres (more frequent than expected due to the car's weight and torque), the 12V battery (keep it charged), and eventual high-voltage battery degradation (managed under warranty for the first 8 years). Beyond that, it's wiper blades and the occasional headlamp washer check.
