Why does a Tesla fail the MFK – the most common reasons explained
Why does my Tesla fail the vehicle inspection (MFK)?
You drive your Tesla to the MFK, step out calmly and think:
“Electric car, low wear, this should be fine.”
And then you get the report: defects found.
For many Tesla drivers, this comes as a real surprise.
👉 Regular inspections, for example every two years, can help prevent unnecessary issues such as increased tyre wear early on.
The reality: a Tesla also has wear and tear
A Tesla does not have a traditional combustion engine.
However, that does not mean the vehicle is maintenance-free.
On the contrary:
Components such as suspension, brakes and chassis parts are often exposed to higher loads than in conventional vehicles.
And that is exactly where the MFK focuses.
TÜV Report 2026 shows a clear picture
Looking at Germany helps to better understand the situation.
The TÜV, comparable to the Swiss MFK, shows in its latest report:
👉 The Tesla Model Y has a defect rate of 17.3%
👉 This places it last out of 110 vehicles
The Model 3 performs slightly better but is still in the lower part of the ranking.
This is not an exception, but a clear pattern.
And these are exactly the issues we see daily at
Hüsser and Palkoska AG, your independent Tesla specialist in the canton of Zug.
The most common reasons why Teslas fail the MFK
Suspension and chassis
A Tesla is heavy. The battery adds significant weight to the vehicle.
This leads to:
- faster wear of control arms
- worn bushings
- play in suspension components
👉 A clear reason for inspection failure
Brakes – a typical EV issue
Many Tesla drivers rely mainly on regenerative braking.
This is efficient, but it has a downside:
Mechanical brakes are used less frequently.
The result:
- rust on brake discs
- uneven brake surface
- reduced braking performance
👉 This is immediately noticed during inspection
Wheel alignment – small cause, big impact
A simple contact with a curb or a pothole can be enough.
Suddenly, the geometry is off:
- the vehicle pulls to one side
- tyres wear unevenly
👉 A classic inspection issue
Lighting – often underestimated
Another commonly overlooked point:
- incorrectly adjusted headlights
- uneven light distribution
👉 Sounds simple, but regularly leads to inspection problems
Why this also applies to Switzerland
The inspection processes in Germany (TÜV) and Switzerland (MFK) are very similar.
👉 In practice, this means:
What fails in Germany will usually also fail in Switzerland.
How the MFK works in Zug
The vehicle inspection (MFK) in the canton of Zug is carried out by the Road Traffic Office in Steinhausen.
If defects are found, you will receive a report listing all issues.
👉 Important to know:
You will be given a deadline to fix the problems and present the vehicle for reinspection.
This is exactly where a specialist makes a difference.

The solution: preparation instead of surprises
We approach the MFK in a structured way.
We check your Tesla exactly as it will be checked during inspection:
- suspension and chassis
- wheel alignment
- braking system including surface condition
- typical Tesla weak points
👉 This way you know in advance what to expect and avoid unnecessary rechecks
If your Tesla has already failed
Even then, it is not a problem.
At Hüsser and Palkoska AG in Baar, your independent Tesla specialist, you receive:

Frequently asked questions
Why does a Tesla fail the MFK?
Mostly due to suspension, brakes or alignment – not because of the drivetrain.
Is a Tesla maintenance-free?
No. The drivetrain requires less maintenance, but other components wear out normally. Tesla recommends an inspection every 2 years or 40,000 km.
Is MFK preparation worth it?
Yes. It saves time, reduces costs and avoids unnecessary rechecks.
