Top issues to watch for
The most serious Tesla Model 3 problems ranked by severity. We track 8 known issues — here are the ones you need to know about first.
Dangerous
Phantom braking and autopilot issues
The forward collision avoidance system can trigger unexpected emergency braking events, known as 'phantom braking', particularly on motorways and dual carriageways. NHTSA data shows 1,638 complaints related to this issue. The system may misinterpret bridges, shadows, or overhead signs as obstacles. Some owners report autopilot being remotely disabled after complaints. This represents the most significant safety concern documented on the Model 3.
What happens if ignoredUnexpected emergency braking at motorway speeds creates severe risk of rear-end collision from following traffic. Tesla may remotely disable autopilot features after repeated phantom braking incidents. No definitive fix exists beyond software updates which may not eliminate the issue.
Major
Suspension pin and bush wear
MOT data shows Model 3 fails at 33.9 times the fleet average for worn suspension components, with 268 recorded failures. The instant torque delivery and heavy battery pack place unusual stresses on suspension bushes and ball joints. Front lower control arm bushes and anti-roll bar drop links are particularly affected. This issue is worsening in more recent data.
What happens if ignoredWorn suspension bushes reduce handling precision and can affect tyre wear. Failed ball joints or control arm bushes can cause loss of steering control. MOT failure is likely if wear exceeds acceptable limits. Early replacement prevents more expensive damage to other suspension components.

Major
Brake disc cracking and weakness
The combination of regenerative braking reducing conventional brake usage and the car's substantial weight (1,600kg+) when brakes are used can cause thermal stress cracking. Discs may weaken from corrosion due to infrequent use rather than wear out from overuse.
What happens if ignoredCracked brake discs can fail catastrophically under heavy braking. Weakened discs reduce braking performance and may not meet MOT standards. Disc replacement on electric vehicles often requires specific parts due to different thermal characteristics from regenerative braking systems.

Minor
Heat Pump Issues
Some Model 3 vehicles experience heat pump failures, particularly in cold weather conditions. The heat pump system is more efficient than traditional electric heating but more complex. Failures can result in reduced cabin heating effectiveness and increased energy consumption as the system defaults to less efficient resistive heating. This issue appears more prevalent on earlier production vehicles.
What happens if ignoredHeat pump failure results in reduced heating efficiency and increased energy consumption, reducing driving range in cold weather. The system typically defaults to backup resistive heating which works but uses more battery power. Repair requires specialist Tesla service due to refrigerant system complexity.
