no, not yet I will try to fix the problem with the shop first
Unfortunately, no relevant information is found.
what happens if I end up filing a complaint and they are responsible?
DMV will take action against the shop. This may include suspending or revoking the shop's registration and/or imposing fines. If you suffer a financial loss due to overcharging or unnecessary or poor quality repairs, the administrative law judge presiding at the hearing may offer the shop the option of paying restitution.
