Why Customers Struggle to Trust Auto Repair [E240]
About this episode
Repair trust is hard because customers can’t verify quality, and the gap between what shops know and what drivers can observe creates information asymmetry. The hosts frame auto repair as a credence-good service and connect it to the “market for lemons,” where deception and misinformation erode confidence. They then point to practical fixes: digital vehicle inspections, before/after photos or video, and citing service information—sometimes even using charging-voltage proof—to “level that playing field” and reduce suspicion.

In this episode, Matt Fanslow continues the conversation around game theory and economics in the automotive repair industry, focusing on one of the biggest invisible forces affecting customer trust: information asymmetry.
Auto repair is a credence good service, meaning most customers cannot fully judge the quality of the work before, during, or even after the repair. A grinding brake noise may disappear after a $200 backyard brake job or a $500 professional repair, but the customer may not be able to tell whether the work was safe, complete, or performed to a professional standard. That gap between what the shop knows and what the customer can reasonably know creates distrust by default.
Matt connects this to economist George Akerlof’s “Market for Lemons,” originally applied to the used-car market, and explains how the same logic applies directly to auto repair. When customers cannot reliably distinguish quality from poor work, lower-quality providers can drag down trust in the entire market.
The episode then turns toward solutions: better documentation, digital vehicle inspections, before-and-after photos or videos, service information references, and clearer explanations that help narrow the information gap without trying to turn every customer into a technician. The goal is not to overwhelm customers with technical data. The goal is to give them enough context to understand what was found, why it matters, and why the repair has value.
Matt also discusses how YouTube, forums, and large language models can complicate trust by giving customers information that may be incomplete, misunderstood, or flat-out wrong. Shops now have to compete not just with other shops, but with customer fear, confirmation bias, and online explanations that may reinforce distrust.

Episode Highlights
Matt explains that customers often cannot tell the difference between a good repair and a poor repair if the obvious symptom goes away. That makes trust harder to earn and easier to lose.
He uses the brake job example to show how two repairs can appear identical to a customer even when one is much safer, more complete, and more professional than the other.
The “Market for Lemons” idea is used to explain how low-quality or deceptive providers can create distrust that affects the entire profession.
The episode stresses that documentation is not just paperwork. Photos, videos, voltage readings, service information, and before-and-after evidence are part of how shops demonstrate value.
Matt argues that shops need to use economic and game theory terms because many of the answers to shop problems already exist in those fields. Without the right language, it becomes harder to find or explain the solution.

“We’re insulating ourselves from a market for lemons.”
Practical Takeaways for Shops
- Use digital vehicle inspections to show customers what is good, what is bad, and why it matters.
- Do not assume the customer understands the significance of a test result. Explain the before and after in plain terms.
- Show comparisons when possible: good versus bad, before versus after, failed versus repaired.
- Reference manufacturer service information when it helps explain why the job requires certain steps.
- Recognize that customers may arrive with fear, skepticism, or bad information before you ever speak to them.
- Trust is not built only by being honest. It is built by making honest work visible and understandable.

pads and rotors
"perceive a difference between a front rake job to cure the grinding by replacing pads and rotors for a bogus number, we'll just say $500 versus the shop down the street that does it for $200"
Pads and rotors are the parts that create stopping power. The pads press against the rotors to slow the car down, and they wear out over time.
Brake pads and rotors are the core wear-and-friction components in a disc brake system. Pads clamp onto the rotor to slow the car; replacing both is a common repair when braking noise or vibration points to worn or damaged surfaces.
front rake job
"There's no way for them to perceive a difference between a front rake job to cure the grinding by replacing pads and rotors"
This is slang for a quick fix focused on the front brakes to stop a noise. It doesn’t necessarily mean the underlying problem was fully addressed.
“Front rake job” is shop slang here for a front-brake-focused repair aimed at eliminating a symptom (grinding noise), rather than a deeper root-cause fix. The host uses it to show how customers may not be able to tell whether the repair was truly correct.
brake lathe
"maybe the shade tree picked up a brake lathe because they're so cheap because we don't really do that much anymore with them. Turn those rotors, resurface them and went below spec, but he's trying to save them money."
A brake lathe is a tool shops use to machine the metal braking surface on rotors. It’s meant to restore the rotor’s surface so the brakes work correctly.
A brake lathe is a machine used to resurface brake rotors so their braking surfaces are smooth and within specification. The host contrasts this with the “cheapest parts” approach, where rotors may be turned/resurfaced below spec, leading to poor outcomes.
resurface them
"Turn those rotors, resurface them and went below spec, but he's trying to save them money. So now they don't know."
Resurfacing brake rotors means machining the rotor’s friction surface to remove unevenness or wear. In this context, the host warns that resurfacing “below spec” can compromise rotor thickness and braking performance.
information asymmetry
"The customer, all they know is that noise went away for $200 and shop A wanted $500 to do it. That's what they know. That's called information asymmetry. We know way more and we should about their vehicles than they do."
It means the shop knows more about what’s wrong and what it takes to fix it than the customer does. When you can’t easily verify what was done, it’s harder to trust the bill.
Information asymmetry means one side in a transaction knows more than the other. In auto repair, the shop understands the diagnosis and what parts/labor are actually needed, while the customer often only sees the outcome (like the noise going away) and the price.
George Akerlof
"Now we have to talk about a gentleman by the name of George Akerlof. He won a Nobel Prize for basically a concept or we'll call it a concept, theory concept called the market for lemons."
George Akerlof is a Nobel Prize–winning economist. He studied how markets can get unfair when buyers can’t tell whether they’re getting a good deal or a bad one.
George Akerlof is an economist who won the Nobel Prize for work explaining the “market for lemons” problem. His research is used here to illustrate why customers struggle to trust auto repair when they can’t verify quality.
market for lemons
"Now we have to talk about a gentleman by the name of George Akerlof. He won a Nobel Prize for basically a concept or we'll call it a concept, theory concept called the market for lemons. He was targeting the used car market, right?"
It’s an economics idea that happens when buyers can’t tell if something is good or bad. If you can’t tell, people may assume the worst, and the whole market gets worse.
The market for lemons is a theory (from economist George Akerlof) describing how quality problems can persist when buyers can’t reliably judge product quality. If bad repairs or “lemons” are hard to distinguish from good ones, trust breaks down and the market can degrade.
gluing bumpers
"but he's a used car dealer and you get to see what he's doing to these cars like gluing bumpers on and stuff like that."
“Gluing bumpers” means someone fixes a bumper with glue instead of doing a proper repair. It can be a warning sign that the car was damaged and the repair might not be solid.
“Gluing bumpers” is a common body-repair shortcut where a bumper cover is reattached or patched with adhesive instead of being properly repaired and aligned. In used-car trust discussions, it’s often a red flag because it can hide prior damage or a poor-quality repair.
fully inspecting these vehicles
"spending money on those vehicles to make sure they meet some minimum criteria, fully inspecting these vehicles."
“Fully inspecting” implies a thorough pre-sale evaluation to verify condition and identify issues before selling. In the trust context, it’s contrasted with sellers who hide problems, so inspection becomes a credibility signal to buyers.
deception
"If the market has deception in it, where there are lemons for sale for $5,000 in quality vehicles that are largely the same"
Here, “deception” refers to misleading used-car listings where a seller’s description of condition doesn’t match reality. The speaker connects it to market behavior: when buyers can’t trust quality claims, they won’t pay “quality” prices.
culture of mistrust
"is this entire culture or environment of distrust climate really climate of mistrust."
A “culture of mistrust” means customers start expecting that something shady is going on. Once that happens, it’s harder for a shop to be believed, even if they’re trying to help.
A “culture of mistrust” describes how repeated negative experiences (or perceived dishonesty) can make customers assume the worst. In auto repair, that mindset affects how people interpret estimates, diagnostics, and recommendations—often even when the shop is acting in good faith.
TPMS systems
"whether diagnosing complex drivability concerns, servicing TPMS systems, validating repairs or working with ADOS and advanced safety technologies."
TPMS means the car has a system that checks tire pressure. If a tire is low, it warns you so you don’t drive on an underinflated tire.
TPMS stands for Tire Pressure Monitoring System. It uses sensors in the wheels (or sometimes the wheel area) to alert the driver when tire pressure is too low or otherwise out of spec.
OEM procedures and standards
"Autel tools are engineered to support accurate, efficient repairs and strict accordance with OEM procedures and standards."
OEM means the car maker. Following OEM procedures means using the manufacturer’s recommended steps and specs, not a guess or a shortcut.
OEM means Original Equipment Manufacturer—i.e., the automaker that built the vehicle. OEM procedures and standards are the exact diagnostic steps, specifications, and repair methods the manufacturer expects technicians to follow.
ADOS
"servicing TPMS systems, validating repairs or working with ADOS and advanced safety technologies. Autel tools are engineered to support accurate, efficient repairs and strict accordance with OEM procedures and standards."
ADOS refers to calibration for advanced safety features that use sensors. After some repairs, the car needs to re-learn sensor alignment so those safety systems work properly.
ADOS here refers to an advanced driver-assistance calibration workflow used after certain repairs. The idea is that some cameras/radar sensors must be calibrated to the vehicle’s current alignment and geometry so the safety systems read correctly.
Autel tools
"Autel tools are engineered to support accurate, efficient repairs and strict accordance with OEM procedures and standards."
Autel makes diagnostic tools that mechanics use to read the car’s systems. The point here is that the tools help shops diagnose and repair cars the way the manufacturer expects.
Autel is a tool brand best known in the shop world for diagnostic scanners and programming/calibration equipment. In this context, the host is saying Autel tools help technicians follow OEM repair steps accurately and efficiently.
digital vehicle inspections
"for those of you that know what a telephone book is, I'm not saying a big, thick stack of papers, but are they being texted their digital vehicle inspections?"
Digital vehicle inspections are a way for the shop to document problems using software, usually with photos or videos. The goal is to show you what they found and what they fixed, not just tell you.
Digital vehicle inspections are inspection workflows done with software (often including photos/video and checklists) instead of only paper forms. They’re meant to document what’s wrong, what’s been fixed, and what changed—so customers can see evidence rather than just hear claims.
ball joints
"We're going to demonstrate this ball joints loose. Here's the video of it. We marked it red because it's really loose and it's causing tire damage and all the things."
Ball joints are parts in the suspension that help the wheels move and steer correctly. If they’re loose, the car can wear tires unevenly and handle poorly.
Ball joints are suspension components that allow controlled movement between parts of the steering/suspension system. When a ball joint is loose or worn, it can cause alignment issues, abnormal tire wear, and unsafe handling.
wheel alignment
"So whatever, however much money we're going to replace the tires and the ball joint to a wheel alignment and depending on the car, maybe an ADOS calibration, boom, it's a lot of money, which is kind of a bogus term."
Wheel alignment is adjusting how the wheels sit and point. If it’s wrong, the car can pull and tires can wear out faster.
Wheel alignment is the process of setting the suspension angles (like camber, toe, and caster) to the vehicle’s specifications. If alignment is off—especially after suspension work—it can lead to pulling and uneven tire wear.
building trust
"I'm showing you the difference. I don't know how many people do that and it is. It's more time and we have to adjust the rates accordingly. We just do. But we're building trust. We're building value."
“Building trust” here means the shop proves what it found and what it fixed. Instead of just saying “we replaced it,” they show pictures or video so you can believe the work was necessary. That makes it less likely you’ll feel like you were misled.
In auto repair, “building trust” means using transparent evidence—like photos, videos, and before/after comparisons—to help customers believe the diagnosis and the work performed. The host frames it as reducing the customer’s reason to distrust the shop, especially when the issue is subtle. This is a key part of customer experience in repair shops.
large language models
"We have the internet. We have resources like YouTube. People can go look into things. There's forums. There's large language models that can get involved and provide. It can be actually quite awful information depending on how you ask it and what the algorithm is."
Large language models are AI tools that can answer questions and write explanations. The host’s point is that they can sometimes give wrong or misleading advice, especially if you ask the question in a confusing way. That can affect how people judge what a mechanic says.
Large language models (LLMs) are AI systems trained to generate text and answer questions based on patterns learned from huge datasets. The host warns that they can produce “awful information” depending on how a question is asked and what the model’s underlying algorithm is doing. In car-repair discussions, that matters because customers may bring incorrect guidance to the shop.
Gemini
"I don't know if you've been using many large language models. When I say large language models, I'm talking about Gemini, chat, GBT, Claude, DeepSeq."
Gemini is an AI chatbot that can answer questions. The host is mentioning it as one of several AI tools people might use to look up car issues. The caution is that AI answers aren’t always reliable.
Gemini is a large language model brand mentioned as an example of the AI tools people might use to research car problems. The host groups it with other chat-style models to argue that the information quality can vary widely. This matters because customers may arrive with AI-generated claims.
chat, GBT
"When I say large language models, I'm talking about Gemini, chat, GBT, Claude, DeepSeq."
This is referring to ChatGPT, an AI chatbot. The host is saying people use these tools to research problems, but the answers can be wrong. If the AI says one thing and the mechanic says another, it can confuse customers.
“Chat, GBT” refers to ChatGPT (often shortened in speech), a large language model brand used for Q&A and explanations. The host lists it alongside other models to emphasize that AI can generate plausible but incorrect information. In repair contexts, that can increase distrust if the customer’s AI research conflicts with the shop’s diagnosis.
DeepSeq
"When I say large language models, I'm talking about Gemini, chat, GBT, Claude, DeepSeq."
DeepSeq is another AI tool mentioned in the list. The host’s main point is that AI answers can be unreliable depending on how you ask. So customers might show up with incorrect expectations.
DeepSeq is mentioned as one of the large language model examples in the host’s list. The key takeaway is not the specific brand, but that multiple AI systems can generate answers with varying accuracy. That variability can affect how customers interpret repair recommendations.
Claude
"When I say large language models, I'm talking about Gemini, chat, GBT, Claude, DeepSeq."
Claude is an AI chatbot. The host mentions it to show that there are many different AI tools people might consult. The caution is that AI can still give misleading answers.
Claude is another large language model brand the host mentions as an example of AI customers might use for research. The segment’s broader point is that AI output quality depends on prompts and the model’s behavior. That can lead to misinformation being brought into the repair conversation.
charging system voltage
"This is what it looked like before. This is what it looks like after. This is your charging system voltage before the alternator, and it was 11.7 volts. And here is your voltage after we put a battery alternator in it, and it's 14.2 volts with all the accessories on."
It’s the voltage your car’s charging system makes while the engine is running. If the alternator is working, the number should be higher than when the car is just sitting. Showing the before-and-after numbers helps convince you the repair fixed the problem.
Charging system voltage is the electrical output your alternator provides to the battery while the engine is running. In a healthy system, voltage rises above the battery’s resting voltage because the alternator is charging the battery and powering accessories. Mechanics often show “before vs after” readings to prove the repair worked.
alternator
"This is your charging system voltage before the alternator, and it was 11.7 volts. And here is your voltage after we put a battery alternator in it, and it's 14.2 volts with all the accessories on."
The alternator is the part that makes electricity while the engine is running. It also recharges the battery. If it’s not working, the battery voltage stays low, and the car can act up.
An alternator is the engine-driven generator that produces electricity for the car and recharges the battery. If the alternator isn’t working correctly, battery voltage can stay low and the car may show electrical issues or fail to start. The transcript uses alternator voltage readings as evidence of a successful repair.
service information
"that is yet another means of demonstrating value, demonstrating trust, service information, reference service information, reference manufacturer, service information, show them if need be, or it's so easy to attach stuff nowadays... Says it right here in service information. The people that built the car said this is the way to do it."
Service information is the official repair manual guidance from the car maker. It tells the technician what to do and what numbers/specs to follow. Using it helps show customers the repair is based on the manufacturer’s own instructions.
Service information is the manufacturer’s official repair guidance—procedures, specifications, and diagnostic steps for a specific vehicle. It’s used to justify the “why” behind a repair and to ensure the job is done the way the car was engineered. The host frames it as a trust-building tool because it ties the work to the manufacturer’s instructions.
