Unconfirmed issues

Reported

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

Front suspension knocks and clunks

Partly in the MOT data

Clunking or knocking over speed humps and rough road, worse at low speed, is one of the most repeated Model Y complaints on owner forums. It's usually traced to worn upper control arm ball joints (moisture getting trapped inside the joint) or torn front lower control arm and anti-roll bar link bushings, showing up from around 40-70k miles. This lines up with the measured MOT data, where suspension is the standout fault category for the Model Y. Out-of-warranty, anti-roll bar links and lower arm bushes typically run £200-450 at an approved centre.

Electronic door handles that stop working

Emerging

A number of owners, mostly on 2021 model year cars, have reported flush door handles going dead with no warning when the 12V system voltage drops, sometimes locking a child in the back seat with no way to get them out short of breaking a window. It's serious enough that the US NHTSA opened a formal investigation covering roughly 174,000 cars in late 2025, but there is no recall or confirmed fix yet and Tesla hasn't acknowledged a design fault. Worth testing every handle, including the rear ones, on a cold start.

12V battery dies with no warning

Emerging

The small 12V battery that runs the door locks, contactors and low-voltage systems can fail suddenly, typically around 3-4 years old, leaving the car completely dead with nothing on the dash to warn you beforehand. Tesla moved to a longer-life lithium 12V battery from around 2021, which cut the complaint rate compared with earlier cars, but it still catches out owners whose cars sit unused for long stretches. Replacement is usually a few hundred pounds at a Tesla service centre.

Heat pump losing cabin heat in cold weather

Confirmed pattern

On heat pump-equipped cars, a software fault could leave a valve stuck open so the cabin loses heating performance in cold weather, sometimes alongside a heat pump error message on the dash. It was serious enough that Tesla recalled over 26,000 Model 3, Y, S and X cars from the 2021-2022 model years and issued a software fix; some cars have needed the physical valve or compressor replaced when software alone didn't cure it. UK owners in cold snaps have also reported reduced heating and range from ice forming over the front air intake sensor.

Fast, uneven tyre wear

Disputed

Owners regularly get through tyres faster than expected, with instant torque, a heavy battery pack and the stock alignment settings all named as contributing causes. The Model Y placed third worst for tyre wear across the UK in Kwik Fit's Maintenance Index, behind only the Model 3. Owners argue over how much is down to driving style versus the car's design, but a full set of replacements can run £600-900 depending on the tyre chosen.

Viewing one? Ask this

Built from the two sections above.

Drive over a speed hump or pothole at low speed with the windows down. A clunk or knock points to the worn front suspension ball joints or bushes that are the most common Model Y complaint.
Cycle every door handle, including the rear ones, especially on a 2021 car. A handle that won't pop out or sits flush can mean a weak or failing 12V battery.
Ask when the 12V battery was last replaced and check the service history. These typically only last 3-4 years and can leave the car completely dead with no dashboard warning first.
On a cold test drive, put the heating on full and give it a few minutes to respond. Weak or absent heat, or a heat pump error message, suggests the valve or compressor fault behind the 2021-2022 recall.
Check tyre tread depth and look across the whole width of each tyre, not just one edge. Even wear across a worn set is normal for this heavy, high-torque car; wear on one edge only means the alignment needs sorting.
Pull the full MOT history and look for repeat suspension or tyre advisories. The same advisory coming back year after year means the underlying wear was never actually fixed.
Check the VIN against gov.uk recalls and Tesla's own recall list. Confirms whether outstanding heat pump or other recall work has actually been carried out.
