I have a 2012 Acura RDX displaying VSA/ABS, brake light and Check emission warning light. There is also a flashing "D" from the gear select and occasionally while driving the air conditioner will cycle off and the cruise control will stop working. I have to restart the car for the AC to come back on. The lights are not on all the time; I may go 2 or 3 days without any lights and they come and go while I'm driving. I have had the car to the Honda and Acura dealership and they have not been able to locate the problem. Acura replaced the steering angle sensor, however, that did not help. I have checked all of the linked fuses as well as all of the grounds in the engine compartment. Any ideas?

 

Tough to diag this without the actual codes. You'll need a code scanner that can read Honda ABS codes for the VSA and (I'm guessing) ABS warning lights.

Foxwell NT510 is frequently recommended on this forum and I also have a Launch Creader Elite which can read these codes. You might also be able to get a parts store to pull the codes for you.
