Hi everyone,

Have a 2018 CPO GLS 450. For the past 3 or 4 months, I have had the Active Brake Assist Functions Limited warning light pop up for about 5 seconds and then go away. Probably has happened periodically about 6 times in that time frame - and it always seems to be when I am doing some tight maneuvering and hit the gas (i.e. pulling out across traffic and then changing from the far left to the far right lanes to make a turn).

I had the car in the shop for regular maintenance and they said that the warnings were the result of a "Low Voltage" code that they could see. They did check the active brake system from front to back, as well as the battery components, and did not see any issues or concerns with anything...has anyone ran into this issue before and know where else I could point them to check? Seems to me like this is not a fluke and the low voltage warning makes me nervous - although it has only happened sparingly and is not a regular occurrence.

Thanks!
