Some questions seem harmless, but they tell your mechanic that you’re not sure what’s going on under the hood. Phrases like “Do I need a tune up?” or “Do I need tires?” open the door for upselling. When you ask these questions, you’re basically handing over the power to decide what your car needs, and what it doesn’t.

Instead, flip the script. Ask what services are due based on your vehicle’s age and mileage. If you’re wondering about your tires, don’t ask if you need new ones. Ask for tread depth measurements and whether wear patterns look normal. Speak with confidence and specifics, not uncertainty.

Planning a road trip or sending your kid to college is exciting, but your mechanic doesn’t need to know about it. Telling them “I’m going on a trip” or “This car is for my son who’s off to college” signals that you’re worried, and willing to spend whatever it takes for peace of mind. That’s when the extra fees start stacking up.

Instead, ask them to ensure the car is in “good working condition” and request a prioritized list of any issues, especially safety related ones. Keep the conversation focused on your vehicle, not your life story.

Saying “Just fix it,” “Do whatever,” or “Take all the time you need” sounds like you’re easygoing, but to a service advisor, it might translate to “unlimited budget.” These phrases give the shop full control over how much work gets done, and how much it costs.

Instead, ask them to follow manufacturer guidelines, get your approval for anything extra, and let them know you want updates. Even if you’re traveling or dropping the car off for a few days, leave a contact number and instructions to confirm any changes or added repairs.
