One problem related to radiator has been reported for the 2007 Lexus ES350. The most recently reported issues are listed below.
Was informed that the engine was in need of replacement after buying and owning for a year. After the vehicle had been in the shop for numerous repairs over the course of a year I ended up having to buy another vehicle and getting stuck with a lien for the Lexus in which the car is non-functional. Paid out of pocket thus far for a number of issues, including: radiator failing, all hoses replaced, axle replacement, to name a few. Car only had 15000 miles placed on it, bought used. Purchased a warranty through the dealership and when attempted to make a claim, claim was denied due to dealership non-payment & "forgetting to file paperwork. " opened up claim with maryland insurance committee and reported dealership for fraud.
