Tesla Model 3 steering rack replacement

Knocking, Noise & Steering Faults – KMC Electric

At KMC Electric, we specialise in diagnosing and repairing steering faults on Tesla Model 3 vehicles, including steering rack noise and internal wear.

This is an issue we are seeing more frequently, where the steering rack develops knocking noises or internal play, often accompanied by warning messages or fault codes.

We offer a complete reconditioned steering rack replacement service, providing a reliable and cost-effective solution.

Common Tesla Model 3 Steering Rack Problems

A worn or failing steering rack can present in several ways.

Typical symptoms include:

• Knocking noise when turning or over uneven surfaces
• Play or looseness felt through the steering wheel
• Clicking or mechanical noise from the front end
• Inconsistent steering feel
• Warning messages on the dashboard

In many cases, the issue develops gradually and becomes more noticeable over time.

Fault Codes Associated with Steering Rack Issues

When the steering system detects irregularities, fault codes may be stored.

Common codes we may see include:

• EPAS_a102 – Steering assist reduced
• EPAS_a066 – Steering system fault
• DI_a137 – Torque / steering plausibility fault
• U0126 – Lost communication with steering angle sensor module

These codes can sometimes be intermittent and are often linked to internal wear within the steering rack assembly.

Accurate diagnosis is essential to confirm the root cause.

Why Replace the Rack Properly?

The steering system is critical to both safety and driving performance.

Replacing only part of the system or skipping alignment can lead to:

Our approach ensures the repair is complete, correct, and long-lasting.
