The car level is fine. Whenever I hit bumps I get the red message ABC issue drive carefully for about 2 seconds then it goes away. Fluid level is where it should be. These are the codes below.

Looks like they had a bulletin out for a software update to address these codes.

However, it appears the issue is the control valves are jamming causing these codes to appear.

There are also issues with the vehicle dropping over time after sitting. This is normally caused by an internal leak so if there is no drop after sitting then the valves are jamming.

I am attaching the info below but based on this info I would think we have an issue with these since you are not losing fluid, or the vehicle is not dropping.

Please run through this and let me know if you agree. Thanks
