Avoid Buying a Bad Used Engine: Lessons from a Prius V Nightmare

The Pitfalls of Automotive Repair

• 🛠️ The primary goal in automotive repair should be to fix the car correctly for the customer, not to play the hero or solely focus on saving money.
• ⚠️ When mechanics attempt to be heroes and things go wrong, customers will blame them, regardless of good intentions.

A Prius V's Engine Woes

• 🚗 This Prius V, with around 150,000 miles, is on its third engine due to a series of repair failures.
• ⛽ The first engine failed after burning oil, exacerbated by an oil change at 125,000 miles, leading to the engine locking up.
• 📉 A subsequent used engine replacement ended disastrously when the drain plug was left loose, causing all oil to drain and the engine to lock up again.

Questionable Repair Practices

• 🔋 Replacing a hybrid battery with a used one is strongly advised against, described as a "class A felony" for hybrids.
• 🔌 Improper wire repairs, such as using tape instead of soldering and heat shrink tubing, can lead to further damage and component failure.
• 💡 Shops attempting to save money by using used parts or performing temporary fixes often cost the customer more in the long run due to recurring issues.

The Dangers of Used Engines

• 📉 The common claim of "60,000 miles" on used JDM engines is often unreliable and misleading.
• ⚠️ It's crucial to analyze the specific engine and its known issues before purchasing a used one; replacing an engine with a known defect with another used one that has the same defect is pointless.
• 📜 Always buy a used engine with a parts and labor warranty and, if possible, verify its service history and VIN.

Consumer Advice for Car Repairs

• 🧐 Consumers should be wary of shops offering significantly lower prices than competitors, as this often indicates corner-cutting or subpar repairs.
• 🎯 Choose repair shops that specialize in your vehicle's make or type; a muffler shop is unlikely to be the best choice for a complex engine repair.
• 💔 The owner of this Prius V has spent a fortune on repairs, yet the car remains unfixed, highlighting the financial and emotional toll of poor automotive service.
