Engine

1.8L 2ZR-FAE

• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher-than-normal oil consumption, requiring frequent top-offs between oil changes. Symptoms include low oil level warnings, visible exhaust smoke (in severe cases), and potential engine damage if the oil level is not maintained.
  • Solution: Regular monitoring of oil levels, using the correct viscosity oil, and potentially a compression test to evaluate engine health. In some cases, piston ring replacement may be necessary, but can be costly.
  • Estimated Cost to Fix: $1,500 - $4,000+
  • Recalls: None Found

Transmission

CVT (K312)

• CVT juddering or hesitation
  • Description/Symptoms: Some owners have reported juddering or hesitation during acceleration, especially at lower speeds. This can feel like the transmission is slipping or struggling to find the right gear ratio.
  • Solution: Perform a CVT fluid flush/change using Toyota CVT fluid. If the problem persists, the transmission may need to be replaced.
  • Estimated Cost to Fix: $200 - $400 (fluid change), $3,000 - $5,000+ (replacement)
  • Recalls: None Found

Suspension

• Rear Suspension Noise
  • Description/Symptoms: Some owners have reported a clunking or rattling noise coming from the rear suspension, particularly when going over bumps or uneven surfaces.
