Common Problems With Tesla Model 3 Suspension and Steering Systems
The Tesla Model 3 incorporates advanced suspension technology to optimize performance and enhance the driving experience. It features a fully independent suspension system with struts at the front and a multi-link configuration at the rear. This configuration allows each wheel to react independently to road imperfections, enhancing traction, stability, and control.
Tesla’s suspension system ensures that vehicle weight is distributed evenly across all four wheels, improving turning performance. Although overall reliability remains high, some common suspension problems have been reported by Model 3 owners.
Some issues have been identified with power steering functionality, wheel alignment, and system electronics. These problems must be dealt with promptly by qualified technicians to preserve control precision and ensure a safe driving experience.
Control Arms
Front suspension noise, such as squealing, cracking, or popping when turning corners or driving on rough or uneven roads might be caused by wear or seizure of the ball joint on the control arms. This problem is more common in vehicles operating in damp, cold environments such as those found in Canada. Since the vehicle’s control arms have been redesigned and improved, this problem tends to be more frequent in Tesla Model 3 cars built before 2021.
Lateral Links
A popping, grinding, or cracking noise can be caused by a torn inner bushing on the lower lateral links. Unlike the control arms, it’s less common for this area to make noise. Nevertheless, during inspection, a technician can check to see if the inner bushing on these links is torn, which will cause additional tire wear and wheel misalignment. An annual inspection is therefore essential to identify worn bushings that impact suspension performance.
Wheel Alignment Problems
Maintaining proper wheel alignment extends the life of your tires. Uneven vehicle geometry will also have an impact on driving performance. When the wheels are misaligned, some areas of the tires bear more weight than they are supposed to. Electric vehicle tires wear out faster than on a regular car, due to the heavier weight and higher engine torque. Uneven weight distribution at the wheels leads to premature and uneven tire wear, which considerably reduces tire life. Annual wheel alignment check-ups ensure that all four tires wear evenly, maximizing tire life and saving you money on early replacements.
Power Steering Failure
One of the most common problems encountered on the Tesla Model 3 is with its power steering. Electric power steering (EPS) systems use an electric motor instead of pressurized hydraulic fluid to assist the steering. Although this technology has many advantages, such as improved energy efficiency and reduced maintenance needs, it comes with its own set of problems. For example, a faulty EPS motor or sensor can lead to a loss or reduction in steering assistance. Any EPS-related error code displayed on the vehicle’s dashboard must be analyzed by a technician as soon as possible. Our NexDrive technicians can help!
Steering Rack Noise
One of the first symptoms of a faulty EPS is a squeaking noise when turning the steering wheel. This noise might be caused by foreign bodies in the steering rack or corrosion of internal system components. In some cases, the entire assembly may fail and require a full replacement. If you hear any steering noise or notice excessive resistance while steering, the system must be checked as soon as possible.
