The most common problems with the Toyota 4Runner, while it is generally recognized for its reliability and longevity, include transmission issues, problems with the Check Engine Light (CEL) due to a faulty charcoal canister, and starter issues due to worn solenoid contacts. Specific concerns for the 4th generation include frame rust, timing chain problems in V6 models, and exhaust manifold cracks in V8 models.
- Transmission Issues: Owners, particularly of older models, have reported automatic transmissions not shifting correctly, especially after reaching high mileage between 125,000 and 150,000 miles.
- Check Engine Light: A frequent cause for the CEL is the failure of the charcoal canister, part of the evaporative emission (EVAP) system, affecting various model years.
- Starter Problems: Issues with starting the vehicle are often due to worn or corroded solenoid contacts, which can be fixed by replacing the contacts instead of the entire starter.
For 4th generation 4Runners specifically:
- Frame Rust and Corrosion: This issue can compromise structural integrity, particularly in climates with harsh winter conditions.
- Timing Chain Problems: These are known to occur in the V6 models.
- Exhaust Manifold Cracks: Commonly found in the V8 models.
Regular maintenance and timely repairs are essential to mitigate these issues and enhance the vehicle's lifespan. For owners who prefer to perform their own maintenance, a detailed service and repair manual can provide valuable guidance. These manuals offer comprehensive instructions for diagnosing and fixing issues, allowing you to handle maintenance and repairs at home and save on professional services.
