The warning lights signify that trouble codes have set and been stored in the vehicle computer(s). Of course, the codes likely reflect the existence of an underlying fault, the severity of which will be unknown until the codes are read by a mechanic and then an actual diagnostic is performed to pinpoint the fault. Codes are merely "clues" to faults; by themselves, codes do not provide a conclusive diagnostic. In your circumstance, you first need a diagnostic to pinpoint the problem(s) and a recommended one would be a warning light diagnostic. If you request that service, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
