I recently purchased a 2019 RDX SH-4WD with the Advanced package. It has just under 30K miles. My friend is a certified mechanic and yesterday we exchanged the brake fluid as routine maintenance. During the procedure, I turned the accessory mode on to roll down a window. The car is now displaying multiple alert signals related to the braking system including low fluid level. The level is fine and the car drives normally. One dealer said there is a throttle at the bottom of the brake fluid reservoir that may be stuck. Tapping didn’t release it. Have an appointment later today. Do I just need to have the computer reset? Thanks!

 

Wanted to post this in order to help others in the future. The brake fluid reservoir has a throttle or bobber towards the back that assists in determining the brake fluid level. When the system was drained yesterday, the bobber became stuck in the depressed position which resulted in any and all the alerts related to the braking system. The mechanic at the dealership used a hook tool to tap the throttle and free it up. I had tapped the reservoir yesterday to do the same but was unsuccessful. All error lights cleared once the car was started.
