On the 2021-2025 Toyota Venza, the 2nd-gen Venza Hybrid can experience 12V auxiliary battery drain and hybrid system errors. The 12V battery drains prematurely if the vehicle sits for more than a week, and some owners report hybrid system warning lights related to inverter communication errors.

This issue also affects: Toyota bZ4X, Toyota Tacoma, Lexus IS

Common Symptoms

  • Vehicle won't start after sitting 5-7 days
  • 12V battery dead repeatedly
  • Hybrid system warning light
  • Ready mode won't engage
  • Multiple warning lights on dashboard

How to Fix

Replace 12V auxiliary battery with AGM type (Toyota recommends their TrueStart battery). Install a battery tender/maintainer if the vehicle sits for extended periods. For hybrid system errors, dealer software update addresses most communication faults. Ensure the 12V battery terminals are clean and tight.

On the 2021-2025 Toyota Venza 2.5L Hybrid I4, the second-generation Venza (2021+) hybrid develops an annoying rattle from loose exhaust heat shields, typically heard at idle and low-speed driving. The shields are spot-welded to the exhaust components and the welds fatigue over time. Since the hybrid system frequently shuts off the gas engine, the thermal cycling is more extreme than in conventional vehicles, accelerating heat shield loosening.

Common Symptoms

  • Metallic rattling at idle
  • Buzzing noise on acceleration
  • Rattle comes and goes with engine on/off cycles
  • Noise worse on cold starts
  • Rattle from underneath the vehicle

How to Fix

Identify the loose heat shield by carefully pressing on each shield with the engine running (be careful of hot exhaust components). Re-secure with large hose clamps ($3-$5 each) around the heat shield and exhaust pipe. Dealers may spot-weld the shield back in place under warranty. As a last resort, the heat shield can be removed, though this is not recommended as it protects underbody components from exhaust heat.

Owner tips & cautions

  • TipTwo large hose clamps from Home Depot ($5) fixed my heat shield rattle permanently. Slide them over the heat shield around the exhaust pipe and tighten. 10-minute fix.
Typical repair cost:$20 - $200
