Along the lines of transmission problems. At 5 days old and 130 miles my ES 350 suffered a Transmission Control Module (TCM) failure. Lights came on, the vehicle exhibited erratic behavior and big RPM swings but, the vehicle was able to be driven to the local (not selling) dealer who repaired the problem. While in the shop, I called the Selling Dealer, and explained my plight and asked when my replacement ES 350 would be ready for pickup. The next day I returned with the repaired unit, to the selling dealer who exchanged it for a brand new, exact copy replacement ES 350. This may be a unique situation but, then there are dealeas and there are DEALERS. THere's a reason I've purchased three (3) Lexi from Lexus of Orlando...........
