Lexus technical service bulletin L-TT-0234-17 for 2018 Lexus LS Hybrid.

Bulletin number
L-TT-0234-17
Component
Exterior lighting: headlights
Summary
TT: Some LC models have been found with a bent front height adjustment sensor bracket. This is causing the headlights to be misaligned when auto adjusting based on the vehicle height position and will set a DTC. Vehicles found shipped by third party tow companies using flatbed trucks are not securing vehicles per the recommendations found in the Owner?s Manual. Some methods seen include strapping the vehicle down using the front lower control arms as a mount point. The height adjustment sensor bracket is fixed to the lower control arm and using this method risks bending the bracket if the strap or chain contacts this bracket under load.
