About this episode

Consumer Reports joins The AutoGuide Show to dig into whether AI can help you buy a car. The hosts explain how they used chatbots and natural-language prompts, but warn that AI can confidently steer you wrong—especially when reliability data is missing for new models or when it invents/misquotes details. They recommend using primary sources, verifying the correct model year, and still driving to catch real-world ergonomics and family-specific deal-breakers.

Technical Too Afraid to Ask
Concept

large language models

"I basically use the chatbot, the large language models, and I spoke to them in natural language 127.1s and I asked the same questions. And, you know, I asked, what's the most reliable 3-row SUV?"

Large language models are AI programs that can read and write text like a chatbot. They can help compare cars, but they can also guess or misunderstand what you really want unless you guide them carefully.

3-row SUV

"and I asked the same questions. And, you know, I asked, what's the most reliable 3-row SUV? 134.9s I asked questions, I asked them to compare different vehicles once they gave me recommendations."

A 3-row SUV is an SUV with three rows of seats. It’s usually chosen when you need space for more people, like a family.

generative AI

"and I used the big, the big guns, chat GPT, Claude and Gemini for that, you know, 144.6s this, these generative AI that I made prompts for. And, you know, at first, and I think everyone"

Generative AI is the kind of AI that creates new answers or text. It can be useful for brainstorming car options, but it can also make mistakes that sound believable.

prompts

"and I used the big, the big guns, chat GPT, Claude and Gemini for that, you know, 144.6s this, these generative AI that I made prompts for. And, you know, at first, and I think everyone"

A prompt is the message you type into the AI to tell it what you want. If your prompt is vague, the AI may suggest the wrong kind of car; if it’s specific, you’ll usually get better answers.

C8 Corvette

"I mean, there's, there's a lot of 220.5s untapped, but on the flip side, some folks will be like, oh, it's completely untrustworthy. 225.5s Like it's not going to say I need a family car for five people and it's going to say C8 Corvette, 230.4s like, no, no, unless you come back to it and, and, and, try to, yeah, but no, yeah."

The Chevrolet Corvette C8 is a sports car with the engine in the middle of the car. It’s not the kind of car you’d pick if you need a 3-row SUV for a family of five.

agentic way

"folks who are actually trying to make this work in a more agentic way to use the, the buzzword. And, you know, that we all kind of came to a consensus"

“Agentic” means the AI tries to do tasks more like a helper—taking steps and checking things—rather than just answering instantly. The host is saying that better AI car advice should include verification, not just guesses.

Toyota Grand Highlander

"the same way that, that the tools did around the Grand Highlander hybrid, that, yeah, it,"

The Toyota Grand Highlander is a big family SUV from Toyota. In this episode, it’s mentioned as an example of a specific car that AI systems might recommend when you ask about “the best” or “most reliable.”

use it like a search engine

"And the first thing I learned is that you don't want to use it like a search engine. It's not something you ask what's, you'll get the same bad answer if you ask one of us, what's the best car because best is subjective."

The host is saying you shouldn’t treat AI like Google. If you ask it a vague question like “best car,” it may give a confident answer that isn’t actually well-supported.

Toyota Highlander

"...now, chat GPT said, for example, the Toyota Grand Highlander, the Hyundai Palisade and the Toyota Land Cruiser..."

The Toyota Highlander is a bigger SUV that can fit more people, usually with three rows of seats. It’s made for family trips and everyday driving when you need extra space. The podcast brings it up as part of the group of vehicles people compare for that kind of use.

Hyundai Palisade

"chat GPT said, for example, the Toyota Grand Highlander, the Hyundai Palisade and the Toyota Land Cruiser, which is an interesting one because it's historically been very reliable."

The Hyundai Palisade is a large family SUV. The host uses it to show that AI can guess at reliability for a newer version, even though real-world reliability data may not exist yet.

Toyota Land Cruiser

"the Toyota Grand Highlander, the Hyundai Palisade and the Toyota Land Cruiser, which is an interesting one because it's historically been very reliable. But, you"

The Toyota Land Cruiser is a rugged Toyota SUV that many people associate with long-term durability. In this segment, the host explains that AI may cite it as reliable, but newer hybrid updates still need real reliability evidence.

reliability data

"And the photo was at the last generation Palisade. We don't have reliability data for the new Palisade. No one can possibly know because we can infer based on the brand, but we don't know how the, you know, new hybrid system, all of those things are new."

Reliability data is information about how often a car breaks or needs repairs after people have owned it for a while. The host’s point is that brand-new versions don’t have that history yet, so AI guesses are risky.

Lexus Gx

"And, you know, on one of them, it gave me the Lexus GX and it said that consumer reports gave it 100 out of 100 for reliability."

The Lexus GX is a Lexus SUV. Here it’s used to show that AI can confidently quote reliability ratings, but you should verify those claims with the original source.

Cadillac XT6

"... they should bring it out. Also the 2026 Cadillac XT6, which is, which was discontinued in 25 that said..."

The Cadillac XT6 is a luxury SUV with room for more than two rows of seats, aimed at family use. The podcast mentions it because it was discontinued, so it may be harder to find and you may be shopping leftover stock. That can change what deals and options are available.

primary sources only

"But you're right, it did pull it from some, in this case, the way I got around this, as I said, okay, go to, go to primary sources only. And then it got a lot better."

Primary sources are the original, most trustworthy documents or data. The host is saying that for car research, you should go straight to the best original information instead of trusting an AI’s summary.

paywall

"The other issue is that places like Consumer Reports, as we see more sort of trusted sources being behind behind a paywall, they're not necessarily going to be, you know, incorporated into the large language models source data."

A paywall is a restriction that blocks access to content unless you subscribe or pay. The host argues that if trusted sources like Consumer Reports are behind a paywall, they may not be included in what AI systems were trained on, which can make AI less accurate for car-shopping research.

game of telephone

"And instead, we'll get this game of telephone where it's this person said that that Consumer Reports said."

It’s like the kids’ game where a message changes as it gets passed along. The host’s point is that AI can repeat secondhand claims and the details can drift away from the original source.

hybrid

"So it sounds like AI is a great, the first step is I think what's really useful if you're not knowledgeable at cars at all, because you're saying like, I want a hybrid three row and you don't even maybe know the names. If you just say like, what are some hybrid three rows?"

A hybrid uses two kinds of power, usually a gas engine and an electric motor, to help it use less fuel. Some hybrids need to be plugged in, but many do not—so it’s important to know which kind you’re looking at.

three row

"because you're saying like, I want a hybrid three row and you don't even maybe know the names. If you just say like, what are some hybrid three rows? At least it'll give you some places to then go ahead and know what a hybrid is."

A “three-row” car has three rows of seats, so it can carry more people than a typical two-row car. It’s a big deal if you need space for a family or passengers.

specs

"Oh, I don't trust their sites. Well, they're going to at least have the specs correct, ignore all the marketing stuff and just read the numbers and then go from there."

“Specs” are the official technical details for a car—like what it’s equipped with and key measurements. The host says AI might get those basics right, but you still shouldn’t rely on it for everything.

Toyota Hilux

"...ourself a diesel forster or something. Yeah, or a Hilux or something, you know, whatever. So it sounds li..."

The Toyota Hilux is a pickup truck, meaning it has an open cargo bed for hauling things. The podcast mentions it while talking about diesel options, which are often chosen for strong pulling power and efficiency. It’s brought up as a practical truck choice.

long list that you then make a short list

"Like, I still think you need a long list that you then make a short list. And then I always say to people, like, don't listen to me, you need to drive the cars."

They’re recommending you don’t rely on one recommendation. Instead, start with many options, then narrow them down based on what actually works for you.

visibility

"And one person will say, you know, the most interesting part is how you feel in the car. And one person will say the steering wheel blocked the speedometer. I couldn't see this. The visibility was terrible."

“Visibility” is how well you can see the road and key areas (like mirrors, blind spots, and the hood/road edges) from the driver’s seat. The host highlights that different people notice different visibility issues during real driving, which is why a test drive can reveal problems that specs and AI can’t.

steering wheel blocked the speedometer

"And one person will say the steering wheel blocked the speedometer. I couldn't see this. The visibility was terrible."

They’re describing a situation where the steering wheel is positioned so it blocks the speedometer. That’s the kind of problem you only notice when you’re actually sitting in the driver’s seat.

seating position

"And then three other people will say, great posture, wonderful seating position, loved it. And that's, you know, these are these things"

“Seating position” refers to how the driver sits relative to the pedals, steering wheel, and controls, including seat height and fore/aft position. The host emphasizes that multiple test drivers can report very different comfort and posture outcomes, which is why driving the car matters more than AI recommendations.

cup holder

"[1088.6s] cups out of the cup holder? Or is it too far a reach for them? And does he have to wait for"

A cup holder is a built-in storage feature meant to secure drinks during driving. In family-focused vehicles, small details like cup-holder reach and placement can matter because they determine whether kids can use them independently.

using in-person experience vs online aggregation

"[1171.1s] something that might be, that might be helpful. But, you know, that aggregation, I think the best [1179.5s] way to do it for a purchase this big is still to, you know, get out of those platforms as much as"

The segment argues that for big purchases like a family vehicle, hands-on inspection and test-fitting matters more than relying on aggregated online opinions. It also suggests that even if AI can summarize sources, it may still miss the specific feature that becomes a deal-breaker for your situation.

fold down center armrest

"[1129.0s] cars are bringing home. So to him, it's like, if I bring something home that doesn't have a [1131.9s] fold down center armrest in the back seat, this is the worst car ever."

A fold-down center armrest is a padded armrest between seats that can be lowered for support. In the rear seat, it can also act as a leaning surface for passengers and may include integrated storage or cup holders, making it a practical usability feature rather than just comfort.

AI agent

"[1145.9s] And that may be the thing that, you know, if you ask, if you ask an AI agent to search one of these, [1153.4s] to search Reddit, to search forums, that may be the thing that pops up"

An AI agent is a kind of computer program that searches the internet and tries to help you decide something. The host’s point is that it might not catch the tiny, personal details that you only notice when you’re actually in the car.

model year

"Actually, then click on the source on the manufacturer website and make sure that it's pulling from the right model year. Because that's, that's one that I saw again and again, it would pull 2024s"

“Model year” is which version of the car you’re looking at (like 2024 vs 2025). Features and measurements can change, so you should verify the specs match the exact year you’d buy.

fact checker

"You have to become a fact checker now. If someone says something, you check it and you make sure, you know, if one of these tools says something, you check it and you make sure that it's, it's correct."

They’re saying you shouldn’t trust AI blindly—you should double-check what it says using the car maker’s official information. Think of it like verifying the details before you buy.

off-road value tire

"This week's product is the Ironhead Thrasher RT-RT-D01 Tire. It is another pretty hardcore off-road value tire."

They mean a tire meant for off-roading that’s priced to be a better deal. The goal is to get strong off-road traction without paying for the most expensive tire.

road noise

"those the same size tires. Now, I didn't do any off-roading with it, but I could compare the [1455.7s] road noise to these Ironheads and I found road noise and vibrations in the steering wheel were pretty good between the two."

Road noise is how loud the tires sound while you’re driving. Different tire designs can make that sound quieter or louder.

vibrations in the steering wheel

"but I could compare the [1455.7s] road noise to these Ironheads and I found road noise and vibrations in the steering wheel were pretty good between the two."

If the steering wheel shakes, it can be because the tires aren’t rolling smoothly. That can come from tire balance, wear, or how the tread hits the road.

slip

"And he was actually quite [1483.3s] impressed with what the tires were doing. He liked how little slip there was on some of the [1488.8s] slipperier obstacles, some of the more sheared-off rub-down rocks."

Slip is when the tire doesn’t grip and starts to slide or spin. Less slip usually means the tire is finding traction better.

tread blocks

"We weren't chunking any rubber [1495.0s] off of the tread blocks in the sand. They dug through and true. Yeah, he said overall he was really impressed with how it works."

Tread blocks are the chunky parts on the outside of the tire. They help the tire grip and can wear differently depending on the surface.

plug inversion

"And there's also, [1661.6s] of course, the plug inversion for a bit more money that gets 127 miles per gallon equivalent, [1666.5s] which is the highest for any plug and hybrid car on the market right now."

The host is talking about a plug-in hybrid—one you can charge at home like an electric car. Because it uses both electricity and gas, the fuel economy is reported in a special way called “miles per gallon equivalent.”
