Frequently Asked Questions

How long does a check engine light service take?

• Typical diagnostic scan and initial inspection: 30–90 minutes, depending on queue and whether the vehicle is drivable.
• Minor fixes (software updates, 12V battery replacement, sensor replacement): often completed the same day.
• More complex repairs (inverter, high-voltage system, battery work): can take several days due to parts and specialized procedures.
• Our dealership provides realistic time estimates on arrival and often moves faster than independents because of direct parts access and factory diagnostic tools.
• If the repair is warranty-covered, it must be completed at a certified dealership to preserve coverage and long-term savings.

What is the first thing to check when the check engine light comes on?

• Review the instrument cluster and driver messages for any immediate warnings or instructions.
• If the light is steady, note recent events (charging interruptions, abnormal noises, dashboard alerts) and safely drive to the dealership if vehicle feels normal.
• If the light is flashing, stop driving and contact Park Place Motorcars Fort Worth for towing — continued driving can cause severe damage.
• Check obvious items like charging cable connection and 12V accessory battery status, but avoid DIY repairs that could void warranty.
