Electric Motor

AC Induction Motor

• Battery Degradation
  • Description/Symptoms: Gradual loss of battery capacity over time, leading to reduced range and performance. This is a natural characteristic of lithium-ion batteries, but can be accelerated by frequent deep discharges or extreme temperatures.
  • Solution: Battery replacement or reconditioning. Battery replacement costs can vary significantly.
  • Estimated Cost to Fix: $12,000 - $40,000+ (depending on battery pack condition and replacement options)
  • Recalls: None Found
• Drive Inverter Failure
  • Description/Symptoms: The drive inverter converts DC power from the battery to AC power for the motor. Failure can result in reduced power, limp mode, or complete failure to start.
  • Solution: Inverter replacement.
  • Estimated Cost to Fix: $3,000 - $5,000+
  • Recalls: None Found

Suspension

• Suspension Component Wear
  • Description/Symptoms: The suspension components such as ball joints, control arm bushings, and shocks can wear out over time, leading to diminished handling, increased noise, and uneven tire wear.
  • Solution: Replacement of worn components.
  • Estimated Cost to Fix: $500 - $2,000+ (depending on the extent of the repairs)
  • Recalls: None Found

Electrical

• 12V Battery Issues
  • Description/Symptoms: The Roadster uses a 12V battery to power auxiliary systems. These batteries are prone to failure, especially if the car sits unused for extended periods. Symptoms include difficulty starting, warning lights, and system malfunctions.
  • Solution: 12V battery replacement.
  • Estimated Cost to Fix: $100 - $300+
  • Recalls: None Found
