When receiving an estimate from a mechanic, if it is unclear whether the price is fair, or when an indicator lights up on the dashboard and you want to understand the cause before going to the service center, AI-based chatbots like ChatGPT are used for these purposes. According to a Wall Street Journal report, the results of such usage can range from real savings to costly pitfalls.
What AI does well
The most direct and least risky application is checking estimates. The user photographs or enters the received estimate, specifies the car's make, model, and year, and then asks the chatbot to evaluate whether the amounts and listed items make sense. AI can identify unnecessary items, prices above the average level, or parts that do not correspond to the described problem.
Furthermore, AI can help explain technical diagnoses. If a mechanic states that 'the MAP sensor is faulty,' and the user does not understand what that means, the chatbot can explain the purpose of this part, its function, and the consequences of its failure, thereby leveling the playing field for the user in conversation with the specialist.
AI can also serve as a useful and economical guide when performing simple repairs, such as changing an air filter, cleaning fuel injectors, or replacing light bulbs, as these tasks are low-risk.
How to use it correctly
It is crucial to be as detailed as possible in your requests. Instead of general phrases like 'strange noise in the engine,' you should describe when the noise occurs, at what speed, whether it is constant or intermittent, and whether it appears only when braking or accelerating. The more context provided, the more accurate the diagnosis will be. You must always specify the car's make, model, and year, and if possible, the chassis number (VIN).
Users are advised to verify advice received from chatbots using other sources. Since chatbots can provide erroneous recommendations with complete confidence, before taking action, especially concerning safety issues, you should consult a trusted mechanic.
If in doubt, it is better to refrain from DIY repairs. Braking systems, suspension, electrical systems, and engines are areas where a mistake can cost much more and be more dangerous than if the problem was initially given to a professional.
Where AI can cause harm
The most common problem reported by mechanics is that drivers replace the wrong part after following a chatbot's advice, leading to expenses exceeding the cost of the initial professional diagnosis.
It is important to remember that AI operates based on probabilities, not absolute truths. It has not heard your car's noise, seen the color of the smoke, or known the vehicle's service history. With electrical or intermittent problems that depend on temperature, humidity, or operating mode, the probability of misdiagnosis increases significantly.
Nevertheless, some mechanics view this technology as an ally. When a chatbot confirms their diagnosis, communication with the client becomes easier. Palmer Dababneh from Underdog Automotive told WSJ: 'AI helps us conduct checks excellently. Therefore, we cannot lie to clients.'
