general problems of the 2016 Lexus RX350

I reported the speedometer issue to Lexus chantilly, va when I drove on highway from va to in, the Lexus speedometer shows 83, and my waze shows 75. Its 8 mph difference. I also have noticed of the mph difference between 6 to 8 mph. Lexus said, I required to pay for the repair, when this speedometer is defected by Lexus design. It has do nothing with personal wear, etc. I drove other Honda pilot, and the speedometer showed correctly against the traffic pattern, and waze app, but the 2016 Lexus doesnt show the correct based on traffic flow, and waze app. The travel from leesburg, va to indiaopolis, in should be 547, but ended at 601 miles. Im ok if its just few miles differences, but 50 miles per every 500 miles is huge, 5% error. I think its because of speedometer and impact error actual miles. I went to Lexus chantilly, va to perform recall for other thing, door handle, but they said, wont look at speedometer issue, unless I pay for it. Then I called Lexus corporation to open the case, and the Lexus case manager wont honor or fix my issue. This is serious safety issue, and should be covered by Lexus due to their defective issue. I have 4 photos to attach. . Can you assist me to contact Lexus to fix based on photos. Thank you. . . I can be reached via bizcham@gmail. Com - cham leang.

Car has hesitation when driving. Car rated for unleaded not premium and should have not to drive car in sport mode all the time.

Brand new car. On freeway middle lane in rush hour and lost throttle. Luckilyi able to get off freeway and called tow truck and went to dealer. Told it is throttle. 2 month old car and 1500 miles. I am scared it suddenly stopped working and am glad I did not meet an accident but scared about this especially as new car. This is safety hazard. Car errors on panel when it failed said; engine, throttle, transmission, awd and safety error.
