I brought my 2018 LC 500 in for Alexa uprade to Lexus of Clearwater 5 weeks ago. The following day I was informed that the software download had failed and that my navigation unit and radio were fried. After many unfulfilled promises of new parts to correct the problem and delay after delay, today I was told the radio was once again on back order until Sept. 11th. This is the 3rd. radio delivery reschedule. Today I was also informed that Lexus does not supply new radios but rather reconditionned ones. I paid $105,000.00 for my LC and also have a multi thousand dollar extended warranty that I purchased and after all the wait without my beautiful vehichle I am now told that the replacement radio will be a reconditionned one. I did not cause the problem; they blew out my system; I believe, by carelessly folIowing the download instructions- I no longer want Alexa. All I want is my vehicle in the same condition that I brought it in. I cannot pick it up since the dash is disassembled. I also own a 2018 LS 500 F Sport. Over $200,000.00 of Lexus vehicles purchased in 2018 and this is how I am treated. A disgrace to Lexus! I would appreciate any help and suggestions. Thank you all.
