There are 1 owner-reported powertrain & transmission complaints for the 2018 Lexus GXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
THERE IS A THUD THAT OCCURS IN THE DRIVE TRAIN WHEN ACCELERATING FROM A STOP, OR ACCELERATING FROM A ROLL. THE DEALER SAID ITS NORMAL, BUT IT CANNOT BE NORMAL. IT IS A LITERAL THUD. I HAVE HEARD THIS THUD COUNTLESS TIMES OVER THE LAST YEAR SINCE WE BOUGHT THE CAR. I HAVE ALSO READ ON MANY FORUMS THAT OTHER PEOPLE HAVE THIS SAME ISSUE.
