* Recalls are vehicle-specific: Recalls are issued by manufacturers for specific vehicle models and years based on serious safety defects. I need more information about your 4Runner (like the VIN or specific engine code) to check for any recalls.
* I'm an AI, not a mechanic: I don't have access to real-time databases for recalls.
How to Find Recall Information:
1. National Highway Traffic Safety Administration (NHTSA): Visit the NHTSA's website (https://www.nhtsa.gov/recalls) and enter your vehicle's VIN.
2. Toyota's Website: Go to the Toyota website and look for their recall section. You'll likely need your VIN or vehicle information.
3. Your Local Toyota Dealership: Contact your local Toyota dealership and provide your vehicle's information.
Important Note: Engine knocking is a serious issue that could be caused by various problems. While a recall might exist for a similar issue, it doesn't necessarily mean it applies to your specific vehicle.
Recommendation: I strongly recommend you take your 4Runner to a trusted mechanic for a proper diagnosis. They can determine the cause of the knocking and advise on the best course of action.
