Several lights can be related to one fault or separate faults. Record the full cluster and scan before treating each light as a separate parts order.
This reference supports the stated topic only. Model, model year, equipment, current rule or individual vehicle conditions may differ; check the original source before acting.

Safety first
Brake, steering, overheating, oil pressure and EV isolation messages take priority. Do not drive if control or braking feels abnormal.
Find the first clue
Note which light appeared first, the exact message and battery condition. A shop should scan all supported modules and their communication faults.
One event can trigger several messages
A system fault may disable other features that depend on its data, so several lamps appearing together are not automatically several failed parts. The reverse is also possible: independent problems can occur at the same time. The only safe starting point is the order in which messages appeared, the vehicle behavior and a scan of all supported modules.
For example, a driver-assistance feature may become unavailable while another system has the primary warning. That does not prove the camera or radar is broken. A weak 12-volt supply can also produce widespread messages, but needs measurement rather than a guess.
Priority and evidence
- Treat abnormal brakes, steering, oil pressure, temperature or propulsion as the immediate priority.
- Photograph the full dashboard and write down which message appeared first.
- Save codes from each module, including U communication codes and their status.
- Ask the shop which fault is primary and which messages are downstream effects before authorizing repairs.
