Hearing that your car needs $4,000 in repairs or it is “unsafe to drive” can make anybody panic. The good news is that a big estimate does not automatically mean you are being scammed, but it also does not mean you should say yes on the spot. Some repairs really are urgent because they affect braking, steering, tires, suspension, or the risk of fire. The key is figuring out whether the problem is truly safety-related, whether the diagnosis is correct, and whether the price is reasonable.
