ALL vehicles have issues, some just more than others, Toyota/Lexus vehicles overall are one of the, if not the most reliable vehicles on the road for many many years now, but that does not mean that things don’t/can’t break sooner or later… Not counting recalls or TSB stuff, all vehicles have at least a small % of issues anywhere from the front bumper to the rear bumper… That being said it is a crap shoot if an extended warranty will be needed or not… And warranty company’s are for profit businesses and count on having a lower % of claims than higher or they would simply go out of business…
That being said, if you have the budget and or able to pull funds to cover expensive repairs then I would be like the warranty company and hope nothing breaks, but if not and it is easier for you to speed X amount of $$ every month over the life of the car payments then the warranty may be better for you… Me or my daughter while in college and paying for her own car, a $5K + repair would be hard to handle with a car payment as well, so I added the Toyota extended warranty to her car, that being said the TPMS sensor (covered under the warranty) went out 800ish miles out of warranty, so basically never had a warranty claim… lol… But for her, it was better to have the warranty and not need it then to need it and not have it… Kinda like a seat belt… Although I have never needed it, I always wear it…
Again the warranty is a crap shoot, but I have also, for customers, used the warranty on 100’s if not 1000’s of vehicles over the years…
