I bought the 10 year extended warranty for the Jeep in my profile pic. It was ~2500 dollar 9 years ago. I had since then in year 8 and 9 everything fail that this model is known for. Air condition compressor, radiator, oil filter housing cracked, transfer case, brake caliber, all 4 wheel bearings (yes, they were covered), power lift gate. Only the transmission hasn't died yet. I think I'm about 10 000 bucks ahead, maybe more as they didn't list labor costs on the warranty statements, only parts.
As you can imagine I'm a fan of extended warranties, especially with new drivetrains and hybrids where a battery failure in 8 years is likely.
From what I see a 10 year warranty may end up around 3-5000 bucks. Has anybody paid for an extended toyota platinum warranty for 10 years and can share the price? I assume there will be ridiculous markups on the warranty and it would be good to have a reference for negotiations.
