Battery Drain & Dead Battery Issues
Problem:
Many 2020 RAV4 owners reported waking up to a completely dead battery, sometimes after the vehicle sat unused for just a few days.
Root Cause:
- The DCM (Data Communication Module) and keyless entry system may continue drawing power even when the car is off.
- Early software versions were especially prone to this issue.
- No response when unlocking
- Warning messages after jump-start
- Battery dying repeatedly
- Toyota released software updates for the DCM
- In some cases, Toyota replaced the battery under warranty
- Some owners temporarily disabled connected services as a workaround

Problem:
Gasoline models with the 8-speed automatic transmission may hesitate, jerk, or feel rough during low-speed acceleration.
Why It Happens:
- Adaptive shift logic needs relearning
- Early transmission control software was overly aggressive
- Delay when pulling away from a stop
- Rough 1st–2nd gear shifts
- Inconsistent throttle response
- ECU reset and relearn procedure
- Updated transmission software
- In rare cases, torque converter inspection
This issue is annoying but not dangerous, and usually improves after updates.Hybrid Fuel Tank Capacity Issue (IMPORTANT)
Problem:
Some 2020 RAV4 Hybrid owners could not fully refuel the tank. The pump would shut off early, limiting usable range.
Cause:
- Fuel tank deformation and internal valve issues
- Manufacturing defect affecting early production units
Toyota acknowledged the issue and issued an official repair program, including:
- Fuel tank replacement
- Fuel sender and filler pipe updates
- Check VIN eligibility at a Toyota dealer
- Request inspection if refueling stops early

Problem:
Water leaks through the roof rails, damaging the headliner and sometimes electronic components.
Affected Vehicles:
- Models with factory roof rails (all powertrains)
- Wet headliner
- Water stains near A-pillars
- Mold smell after rain
- Insufficient sealing of roof rail mounting points
- Toyota service fix includes:
- Removing roof rails
- Proper sealing
- Reinstallation with improved gaskets
This should be fixed ASAP to avoid interior damage.
Infotainment & Apple CarPlay Issues
Common Complaints:
- Apple CarPlay disconnects
- Touchscreen lag
- Bluetooth instability
These are software-related, not hardware failures.
Solutions:
- Head unit firmware updates
- iOS compatibility updates
- Cable replacement (certified cables only)
Suspension Clunking & Ride Noise
Issue:
Some owners notice clunking or knocking sounds when driving over bumps.
Typical Causes:
- Stabilizer bar bushings
- Strut mounts settling
- Bushing replacement
- Torque inspection during service
Steering Wheel Noise or Clicking
Problem:
Clicking or rubbing noise when turning the steering wheel, especially at low speeds.
Cause:
- Steering column lubrication points
- Dealer lubrication or column component adjustment
