I have just had my first claim on my extended warranty (took it out at the very end of July after I bought the car, replaced the rear shock (£800) and the 100+ service (£595) and MOT at Lexus - before discounts).
My passenger headlamp (main lamp and full beam lamp) was misting up when I bought the car, but causing no issue (and one back taillight too).
It was on my list of jobs to strip the front end and dry it out, reseal it etc. However, the light stopped working - dead - one night, and dead for days, even when I tried swapping bulbs left to right, hairdryer on it etc. Called Lexus, got it booked in for inspection a few days later - in the interim it started working again!
Diagnosed by Lexus as a failing ECU (the ballast) the seal no longer working on the lense and needed a new bulb - £937 fitted!
Waited to hear back from warranty when filed, did tonnes of research and was ready to do all the work myself (new ballast, pair of bulbs, strip & reseal lamp etc).
Came back - fully approved - all cost covered. The car is 9 years and 10 months old today. The warranty has now paid for itself in one go!!
Always been good for me in the past - both Toyota and Lexus ext. warranty.
