When "Start Error" is displayed in the Cluster it means that there is a problem with the Immobilizer system. This can be caused by a faulty key, faulty receiver antenna on the key cylinder, faulty wiring for the immobilizer module, the SKREEM Module (immobilizer module) and/or the ECM.
At this time I HIGHLY recommend to have the vehicle looked at at the Dealer. I would do this ASAP as it is only a matter of time before the vehicle will not start at all. Of course this will be at the worst time.
If you need additional information, don't hesitate to ask, I am happy to help as long as necessary to help solve your concern. Remember, a "Positive" Rating will not close this question, You can post a reply here whenever you want, even after rating my answer!
