Reliability verdict
ABy miles

Graded against its peers

One of the best small SUVs per mile driven. Watch suspension and brakes. A solid used buy, provided its MOT history has no repeating suspension advisories.

What owners report

Reported

Owner folklore from forums and the motoring press, with how well each report stands up. Most of it never shows up in an MOT, which is why this section exists at all.

Electronic door handles failing (water ingress)

Confirmed pattern

The ID.4's flush, touch-sensitive door handles use a sealed switch and control unit, and water getting past the seal can make a handle stop responding or, in rare cases, let a door release while the car is moving. VW UK issued a safety recall (R/2025/516, November 2025) covering just under 23,000 UK-registered ID.4s built between June 2023 and September 2025, and the same handle design caused a production stop-sale while parts were sorted out. The fix is a free dealer software update that makes a fault show up as a warning rather than failing silently, so check it's been done.

12V battery drains flat and kills the car

Emerging

The small 12V battery runs the locks, contactors and infotainment while the car sits, and owners report it going flat even with the main traction battery fully charged, which leaves the car completely dead and unable to boot up until it's jump-started or replaced. It's turned up repeatedly on owner forums on both sides of the Atlantic, at all sorts of ages rather than one obvious point in ownership. The battery itself isn't a big-ticket item, roughly £150-£350 fitted, but repeat failures mean repeat dealer visits, and none of it shows up on an MOT.

Infotainment screen freezing and slow to boot

Emerging

Early cars are reported to have a laggy, sometimes confusing infotainment system, with the screen freezing, rebooting on its own, or taking a while to wake up when you get in. VW's later software (the 3.x update rolled out from 2023) is widely said to be a real step up, so a 2021-2022 car that's never had a software update is the one most likely to still misbehave. It's a nuisance rather than something that leaves you stranded, and the fix is free, but repeated freezing on a test drive suggests a car that hasn't been kept current.

Front strut and rear suspension knocks

Partly in the MOT data

A recurring forum complaint: front struts described as leaking or 'blowing' a seal, plus clunks and rattles from the rear suspension over bumps and potholes. It's been raised independently on several separate UK and US owner forums, at a spread of mileages rather than one clear failure point. The measured MOT data for this model backs it up too, with suspension standing out as the top fault category, so the knocks and creaks owners describe line up with what's actually failing on the test lane, not just forum chatter.

Sudden loss of drive power

Emerging

A minority of owners report the car briefly losing drive or refusing to pull away, which write-ups have traced to the battery management or motor control software rather than a mechanical fault, and which VW has addressed with software updates in some markets. It doesn't happen to most cars and there's no clear pattern by age or mileage, but it's been reported often enough across owner and press sources to flag. In warranty, it's a free software fix; out of warranty, a genuine drive unit or battery control module fault would run to four figures.

What to check on this car

Ranked from this model’s own MOT record, then from what owners report.

Saveable checklist

From this model’s MOT record

The physical checks its own defect data says are worth your time, most telling first.

DampersRuns high on this model Look for oil misting on the damper body behind each wheel, then push down hard on each corner of the car. It should settle in one bounce. A floaty or crashy ride on the test drive is the same fault felt from the driver's seat.Recorded on 3.4% of tests at age 3-5 · class average 2.1%
Bushes and ball joints Drive slowly over broken tarmac with the windows down and listen for clonks from either end. Back at the car, have someone rock the steering wheel while you rest a hand on each front wheel; play you can feel through the tyre is a worn joint.Recorded on 2.0% of tests at age 3-5 · class average 2.4%
A binding brake After the test drive, hold the back of your hand near each wheel hub. One wheel running much hotter than the rest is a sticking caliper. A car that slows itself down when you lift off on a flat road is saying the same thing.Recorded on 0.8% of tests at age 3-5 · class average 0.3%

Worth doing on any used car

These judge the seller’s upkeep rather than the model, and they are where the haggling money is.

Tyres, all fourRuns high on this model Check the tread across the full width of each tyre, inner edge included, and look for cracking and mismatched brands. A set of decent tyres is £500 or more on most cars, which makes this the easiest money to take off a price. If the pressure warning light is on, budget for sensors too.Recorded on 28.6% of tests at age 3-5 · class average 16.6%
Windscreen and wipers Scan the glass in daylight for chips, especially in the driver's line of sight where even a small one can fail the MOT. Run the washers and check the wipers clear without smearing.Recorded on 1.4% of tests at age 3-5 · class average 1.4%
Pads and discs Look through the wheel spokes at the brake disc. A pronounced lip on its outer edge, or a rusty and scored face, means discs and pads are due all round, a few hundred pounds on most cars. A haggling point rather than a reason to walk away.Recorded on 0.9% of tests at age 3-5 · class average 7.0%

Because of what owners report

Drawn from the reports above rather than the MOT data. These are the model-specific ones.

Open and close every door handle from both inside and out, including in the rain if you can. A handle that hesitates, needs a second press, or doesn't respond points to the water-ingress fault.
Check the VIN on gov.uk's recall checker or ask the dealer for the recall history. An outstanding door handle recall (R/2025/516) or others not yet actioned is a free job the seller should have already sorted.
Ask for evidence of a 12V battery replacement in the service history. One replacement is normal wear; more than one hints at an ongoing drain that hasn't been fixed.
Start the car cold and cycle through the infotainment menus. Freezing, a slow boot, or an unresponsive screen suggests old software that hasn't been updated.
Drive over a rough road or speed bumps at low speed, windows down. Knocking or clunking from the front or rear suggests the suspension wear this model's MOT data flags up.
Accelerate hard from a stop two or three times during the test drive. Any hesitation or momentary loss of power is worth asking the seller and a VW dealer about before buying.
Check the estimated range against the official figure for the battery size and age. A big shortfall suggests battery degradation beyond what you'd expect for the mileage.
