Frequently Asked Questions
Please reach us at steve@energized-ev.com if you cannot find an answer to your question.
How long does high-voltage battery replacement take?
High-voltage battery replacement typically takes about one day once the vehicle is on the lift and the replacement battery is available.
How long does high-voltage battery repair take?
High-voltage battery repairs usually take 1–2 weeks, depending on the complexity of the issue and diagnostic findings
How long does a Tesla Large Drive Unit (LDU) rebuild take?
A typical Large Drive Unit rebuild takes approximately 1–3 days, depending on the condition of the unit and parts availability.
Do you only work on Tesla vehicles?
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.
What are common signs of a Tesla high-voltage battery problem?
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.
Can Tesla battery packs be repaired, or do they always need replacement?
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.
What is the Tesla Large Drive Unit coolant leak issue?
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.
What symptoms indicate a Tesla drive unit problem?
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.
Do you work with insurance companies for accident repairs?
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.
What is a high-voltage isolation fault?
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.
How long does the diagnostic process take?
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.
Do you offer suspension repair services?
Yes. We replace worn or damaged suspension components including control arms, bushings, shocks, struts, and air suspension components.
