When I drive at above 60 mph, there is a rattling sound. I took it to the dealership and they are unable to pinpoint the issue even after removing the roofrack, the roof insulation and tightening all the bolts. I have found numerous postings online but Lexus still refuses to let us know the issue. Please help! it is very concerning that a loose part might cause major accident or event death. . Read more...
Shortly after buying the vehicle used (one previous owner), upon cold start a loud rattling noise could be heard coming from the engine area for about 30 seconds. Took to a Toyota/Lexus dealership for routine oil change, vehicle inspection, and asked the technicians to also address the noise. We were told that they couldn't reproduce it, and that it shouldn't be a problem. Driving down the freeway in greater milwaukee, the car stopped functioning. After visiting a local mechanic, then later resorting to a Lexus dealership, found that the vvt bolts had fractured. All of this is exactly as outlined in NHTSA campaign 13v395000. Now we have a dead luxury SUV due to an engineering problem, but Lexus will not provide any resolution to their known problem, even with physical evidence (photos, and failed parts still in hand).
