Tesla Model S Common Problems & Reliability
The Tesla Model S is the groundbreaking luxury saloon that proved electric vehicles could offer blistering supercar performance and genuine cross-country range. In the UK, it shattered the dominance of the German executive class, offering access to the unmatched Supercharger network and constantly evolving over-the-air updates. Early models (2014-2017) are known for rapid depreciation due to "first-generation" build quality issues, but later "Raven" models are highly refined. Note that from 2022, Tesla controversially stopped producing Right-Hand Drive models for the UK. It suits tech-savvy executives and early EV adopters wanting massive range and straight-line speed.

Most Common Tesla Model S Faults & Repair Costs
Retractable Door Handles
The flush-fitting motorized handles frequently fail to present or unlatch due to broken internal micro-switches or "paddle" gears.
Handle won't pop out, Handle pops out but door won't open, Intermittent operation
- Test every handle multiple times
- Listen for motor whirring without movement
- Check for loose handle feel
MCU1 eMMC Memory Failure (Recall 21V035)
The main touchscreen unit (MCU1) uses an 8GB eMMC chip that has a finite lifespan, eventually leading to system instability or total failure. Tesla issued a voluntary recall (21V035) to upgrade the chip to 64GB.
Screen freezing or rebooting, Longer boot-up times, Total screen blackout, Loss of climate controls
- Check if upgraded to MCU2 (faster, Netflix/YouTube present)
- Check for lag in navigation
- Verify backup camera loads quickly
Suspension Control Arm Creaking
The front and rear suspension control arms (wishbones) can develop a loud creaking or squeaking noise, particularly when turning or going over bumps, caused by water ingress into the ball joints.
Squeaking noise when turning, Knocking over speed bumps, Unsettled handling
- Listen for creaks while steering at low speed
- Inspect ball joint boots for splits
- Test drive on rough surfaces
Yellow Screen Border
A yellow tint can develop around the edges of the main touchscreen (MCU1 and early MCU2) due to an adhesive failure in the display stack.
Noticeable yellow band around screen edges, Discoloration on white backgrounds
- Open a white page (like the web browser) to check for yellowing
- Verify if the UV light treatment has been performed by Tesla
Drive Unit "Milling" Noise
An internal bearing failure in the drive unit can cause a high-pitched whirring or "milling" noise that increases with vehicle speed.
High-pitched whirring noise, Vibration at speed, Power reduced alerts
- Listen for noise during acceleration and deceleration
- Check service history for drive unit replacement
- Test at motorway speeds
Air Suspension Leaks
The air suspension struts or compressor can fail, causing the car to sag or display suspension fault messages.
Car sits low on one corner, Hissing sound from wheel arch, Suspension height error messages, Compressor running constantly
- Check ride height after car has sat overnight
- Cycle through all height settings
- Listen for air leaks
Buying a used Tesla Model S? Always check for hidden finance and write-off history.
Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.
