What 2015 Lexus CT owners say
Brakes
received CUSTOMER SUPPORT PROGRAM 24LE01 NOTIFICATION for issues related to Brake Booster and Brake Booster Pump Assemblies. Indicator lights, such as Master Warning Light (Yellow) and SLOP Indicator (Yellow) have appeared while reversing out of a parking spot when no water puddles are present and moving foward (clear day/road) where the vehicle doesn't catch the gear to move initially. Once braking, the system seems to reset itself and allows for a "normal drive". The experience is intermittent, and not often- the dashboard warning lights come on infrequently and is not consistent. Lexus Dealer/Service Shop advised a charge of $145 to look for diagnostic codes C1391, C1252, C1256, C1253. …
I noticed that the brakes felt a bit weird when engaged. I felt a touch on the brakes and heard as if the abs pump was pumping. Thinking it was something of a fluke, I didnt pay any further attention to it. After not driving the car for couple of days, when I turned on the car a day ago the warning (!, brake, ABS, and traction control lights) are all lit up on my 2015 Lexus CT200h. After doing some research, I have found an old recall for Lexus CT200 H for (2011-2014) see (L-SB-0009-210) from May 11,2021 letter online. A code scan revealed a C1391 error, indicating an abnormal leak in the accumulator. This ABS module is the same as the recalled Toyota ABS module. Please this could be dangerous to me and my family.
