Frequently Asked Questions

High-voltage battery replacement typically takes about one day once the vehicle is on the lift and the replacement battery is available.

High-voltage battery repairs usually take 1–2 weeks, depending on the complexity of the issue and diagnostic findings

A typical Large Drive Unit rebuild takes approximately 1–3 days, depending on the condition of the unit and parts availability.

Yes. Energized-EV specializes primarily in Tesla vehicles and Tesla-based electric powertrain systems. Our focus on Tesla high-voltage battery systems and drive units allows us to provide more specialized diagnostics and repair solutions. 

Common symptoms may include:

• Battery warning messages on the display
• Reduced driving range
• Charging failures or slow charging
• Vehicle unable to shift into drive
• High-voltage system alerts

A proper diagnostic evaluation is required to determine the root cause.

In some cases, battery packs can be repaired depending on the type of fault and the condition of the modules. Our diagnostic process helps determine whether a repair, module replacement, or full battery replacement is the most practical solution. 

Certain Tesla Model S and Model X vehicles equipped with the Large Drive Unit (LDU) may develop coolant intrusion due to internal seal failure. Over time, coolant can enter the rotor cavity and cause internal damage.

Energized-EV offers coolant delete installation using a custom manifold solution designed to eliminate this failure path.

Common drive unit symptoms include:

• Grinding or whining noise from the motor
• Drivetrain warning messages
• Reduced power alerts
• Vehicle entering limp mode
• Coolant related faults

A diagnostic inspection is required to determine whether the issue involves the drive unit or another drivetrain component.

Yes. We provide inspection and repair services for Tesla vehicles involved in collisions, including evaluation of high-voltage battery systems, drivetrain components, and suspension damage. 

A high-voltage isolation fault occurs when electrical leakage is detected between the high-voltage system and the vehicle chassis. Tesla vehicles will often disable driving or charging functions until the fault is resolved.

Our diagnostic process identifies which component within the high-voltage system is responsible.

Diagnostic time varies depending on the issue. In most cases, initial evaluations can be completed within a few days once we have access to the vehicle and relevant system data. 

Yes. We replace worn or damaged suspension components including control arms, bushings, shocks, struts, and air suspension components.
