### **Should You Buy a 2018 2020 LS 500 with the Right Piston Issue?**
#### **Recommendations Based on Your Situation**
1. **If You Find a Vehicle with the Right Piston/Connecting Rod Issue:**- **Get a Lexus Dealer Inspection First**
- Lexus has **officially acknowledged the issue** and is **offering free repairs** for affected models.
- **Check if your VIN is on the recall list** ( NHTSA Recall Database (https://www.nhtsa.gov/recalls)).
- If the issue is confirmed, **Lexus will replace the piston/rod assembly at no cost**.
- **Avoid Buying Without Confirmation**
- If the seller **refuses to disclose the issue** or **won t let you check**, walk away this could be a **scam or hidden problem**.
- **Get a Pre-Purchase Inspection (PPI) from a Lexus Specialist**
- A **mechanic familiar with the 2GR-FKS engine** should **listen for knocking noises, check oil pressure, and inspect for misfires**.
- If the engine sounds **normal under load**, the risk may be low but **noises at high RPMs are a red flag**.
2. **If the Vehicle Has Already Been Recalled & Fixed:**- **This is the safest option.** If Lexus has **already replaced the piston/rod**, the risk is **eliminated**.
- **Ask for service records** to confirm the repair was done.
3. **If You re Buying from a Private Seller (Not a Dealership):**- **Demand a full warranty or at least a 30-day test drive.**
- **Get a written statement** from the seller that the engine has **no known issues**.
- **Consider a shorter-term lease or rental** to test the car before committing to a purchase.
4. **Alternative Options If You re Worried About the Issue:**- **Look for a 2017 or 2021 LS 500**
- **2017 models** are **less likely** to have the piston issue (though not impossible).
- **2021 models** have **updated engines (2GR-FKS with minor improvements)** and may be **less prone to the problem**.
- **Consider a Lexus GS 500 or RC 350**
- These models **use the same 3.6L V6** but have **different piston/rod designs**, reducing risk.
- **Explore Competitors with Turbocharged Engines**
- If you want **more power**, a **BMW 530i, Mercedes E350d, or Audi A6 3.0T** may be worth considering (though they have their own **turbo lag and reliability concerns**).
5. **If You Decide to Proceed:**- **Budget for Potential Future Costs**
- Even if the piston issue is fixed, **regular maintenance (oil changes, timing belt, spark plugs)** is essential.
- **Avoid high-mileage examples** (
