关于Lemon Car

2023二月底购入Tesla Y新车(加州)，大概两三个月后，开车时显示屏会突然出现notifications: vehicle may not restart, service is required。去了Tesla Service Center六次，没有修好。我在9月filed a dispute, 10月收到并同意仲裁结果: Repurchase。按照CDSP(California Dispute Settlement Program)条款："if the consumer accepts it, the manufacturer must perform the arbitrator's decision within 30 days of the consumer's acceptance of the arbitrator's decision." 但是已经三个月了，Tesla 根本不理。我联系了CDSP好几次，得到的回复都是：The decision is binding on the manufacturer. CDSP monitors compliance and we do not have jurisdiction to penalize the manufacturer for delays encountered; however, we will continue to request updates regarding the compliance delay.  

请问：1. 我还可以继续开这车吗？不然我和我先生要共用一辆车。2. 我继续这样茫然地等呢还是仍然要找律师？谢谢!!!
