Consumer Description

On 05Jun23, EQS 450+ suddenly reduced the speed to 30mph on the SRT highway while I was driving with cruise control set to 70mph. This creates sudden deceleration in the car and slow down as well as on the left lane traffic where there was a following car behind me with high speed. This happens multiple times when I was driving on the different highways in Texas as well as in FM roads. Car’s Behavior while Cruise control is SET to 70+mph and Intelligent Recuperation is ON. Highway Speed Sign is 70mph. 🔴 Sudden, unexpected deceleration 🔴 Wrong speed sign pops up on the dashboard 🔴 Confusing warning sound 🔴 Speed sign Indicator acts like inconsistent or confused by changing from 30mph to 45mph or vice versa.
