**Pre-Purchase Checklist**

When buying a used car, it's essential to have a mechanic check out any late model car before you buy it. This is because someone could potentially steal and sell a new car with a fresh coat of paint, only to rack up damage on it immediately after purchasing it. Having a professional inspect the vehicle can help identify potential issues before they become major problems. Additionally, having at least two good keys on hand can also be helpful in case one key is damaged or worn out.

**Keyless Entry Issues**

T-series says that their keyless entry barely works, sometimes requiring multiple presses to lock the doors. A simple solution to this issue is to disassemble the fob and replace the battery. This can often resolve the problem, as many modern cars rely on a weak or dead battery to function properly.

**Understanding Your Warranty**

Maggie C shares her experience with a 2021 RAV4, which had its shocks break after only a short time. While it's not uncommon for vehicles to experience some wear and tear over time, having your vehicle checked by a reputable mechanic can help identify the root cause of the problem. In Maggie's case, she believes that the issue was likely due to poor road conditions, rather than any fault with the vehicle itself.

**Choosing the Right Scan Tool**

Mr. Pond asks for recommendations on good sub-$100 scan tools for Japanese cars. He suggests looking at the Innova Scan Tools, which offer a range of models at different price points. While the top-of-the-line model can cost over $300, there are also more affordable options that still offer a significant amount of functionality.

**Luxury Mid-Size SUVs**

Drone Production questions whether a 2015 Acura MDX is a good luxury mid-size SUV. The answer is yes, as these vehicles are known for their quality and reliability. However, it's essential to get them thoroughly inspected to ensure they meet your expectations. With proper maintenance and care, an Acura MDX can be an excellent choice for anyone looking for a luxurious and dependable vehicle.

**Rust Repair**

James Walker asks about the best product for cleaning up a rusty frame on an old Toyota pickup truck. One effective solution is to blast off any remaining rust with a hammer or wire brush, followed by applying anti-rust coating, priming, and then painting the affected area. However, if the rust has completely taken over the frame, it may be necessary to replace the entire structure. In such cases, it's often more cost-effective to opt for a rebuilt or replacement frame rather than attempting to restore the original.

**Tips from the Community**

"WEBVTTKind: captionsLanguage: enrev up your engines well a bunch of owners do deep grand cherokee owls have faulty key fob electronics and now cherokee is a giant brick that they can't drive now these are the super expensive three row jeep grand cherokees that they revealed last year and what's happening is the key fobs do not connect to the vehicle and they're immobile and you can't drive them key fob technology sx you've been around for quite some time no surprise that stellantis and jeep and fiat don't have the intelligence to build them correctly because all they do doing is making as cheap as possible sell for as much money as possible and keep their fingers crossed and hope that they don't break before the warranty's up now this is affecting 2022 model year grand cherokee else soon the 2023s will be out so they can could have been out eight nine months but still they break that fast the owners of these jeeps the computer in the jeep seems to forget that that's a good key and it won't let it start if you know how a lot of these kilo fobs work they usually have a secret key inside so you can not get in the door but the problem is was the one woman she tried to open the car with a key and she did but then when she got in they thought the jeep thought it was being stolen it shut everything off and once the data turned a woman's alarm on she couldn't unlock lock a car or do anything because the alarm's going off and thinks the car's being stolen another guy alex he had one and he says bought jeep on saturday had it towed to the dealer sunday he just got it it didn't work talking about horrible quality control could you imagine you pay all that money for one of these things you can't drive it the day after you buy it because you can't get in because the stupid keyless system doesn't work correctly i don't care what anybody says these keyless systems are a bunch of crap they cost a fortune to fix when they break if you want an anti-theft system the absolute best thing is what a lot of companies including toyota used in the past and they still using their cheaper cars is a regular key that's got a cut key with an immobilizer so you need both a key and the immobilizer chip to start the car as i've shown in other videos stealing a keyless fob car is easy for a professional thief they can just steal the communication they can have a blank key fob then they get in your car with the machine that i have and they could just reprogram it drive the car away and that's how some cars are being stolen these days it's actually a less safe system i gotta admit it's a safe system because the owner can't even drive the car so maybe don't think about buying one of jeep's products then you have to worry about being stuck in something like this because the idiots built a car that so far these people they said they can't figure out what's wrong and they're sitting at the jeep dealer waiting to be fixed the new car that they just bought or one that is a few months old that decides it's not going to communicate with the keyless ignition system and the car won't start and eventually if you use the key to get in it won't even let you get it out lock it anymore because it thinks someone's stealing the car sebastian says i got a question about honda transmissions i know honda used to have a problem with automatic transmissions i think they were jetco i heard they're better what do you think about honda and jet co-automatic transmissions well unfortunately you've got bad information as far as i know honda never used jetco transmissions they designed their own and then back in the past you go back 20 30 years ago some of the honda automatic transmissions were relatively weak especially the ones hooked up to the powerful v6 engines and they could burn up honda is a very good engineering company as time went on they've improved their stuff and especially you take the modern honda transmissions honda designs and builds them all and i believe they always did anyways my son's got one he loves it and he drives like a maniac and he still gets great gas mileage so honda is a good engineering company and they learn from their mistakes everybody makes mistakes i've made mistakes tell you what the mistakes i've made they're burned into my brain so i don't ever make them again that's the thing about a mistake you make a mistake and you're smart and you're honorable you learn from it you never make it again and you do a better thing the next time and if you're an engineer you say oh geez we screwed up he made that bearing wrong so let's make the bearing better and let's never screw up like that again always make sure that bearing is really good and honda's that way so i wouldn't worry about the modern ones but they never did use jacko transmissions husky says police cars are strong they claim they're well maintained but what do you think about buying police car municipal used vehicles at auction i am not a fan of people buying police cars because the police drive like maniacs got police friends in houston they drive like maniacs they don't care it's not their car they smash into things they fly over curbs or they're chasing after criminals i would not buy one unless you wanted to buy a shell of a car and rebuild it you want to do that that's perfectly fine but buying the police cars big mistake in most cases unless there were certain types of police cars like i know a guy here clarkson bought one and it was a narcotics officer undercover so he just drove it normally he didn't chase after people and it still ran pretty good when he bought it a lot of times you get fleet municipal vehicles they can be okay vehicles if they're not too high miles a lot of times they don't put that many miles out so that's a better deal but they used cop cars like in the blues brothers you know they got theirs they fly over the bridge in chicago and land on the other side if it really was a cop car and dinner i suppose it probably would have broken in half when it actually did unless you're planning on rebuilding the car entirely it's not a good idea to buy a used police car they have the hat beat out of them generally chris 598 says does anyone know what this warning light means i have an orange warning light coming up it only happens when it idles when i open the door and shut it shows up for three seconds it makes a beeping sound and the warning light goes away it has an exclamation part inside it that's on the top left corner if you got a key fob change the battery hopefully that fits if you have another known good key fob use that and try it thinks the car is being stolen it's not working correctly with the electricity going from there to the car now sometimes those systems go a little hair wire the security systems if your battery's low so find a guy like me put up a machine load test your battery could just be a low battery they'll often do something like that simple fix but if it isn't you got a problem with your key fob system try a new battery or try another known good one if you find your other key fob starts it and the one that you have doesn't go get another one made because you always want to have two good ones okay something happens that's why you want to always have a good second key got a problem with that system first try no good key if that fixes then get rid of your other king get another one everything wears out including the keys and those stupid fobs eventually wear out too david brown says my daughter's looking at a 19 cx-5 turn 2.5 liter end sky active transmission all-wheel drive what's your opinion mazda quality has been going up toyota owns i don't know 20 or something they've got a deal going where they're making mazdas and toyotas on the same assembly line someplace in alabama i believe they are much better made and that is usually a pretty well made now it is a used car as i always warn people i know i sound like a broken record but pay mechanic like me to check it out before you buy it you never know if it was wrecked or flooded you don't want to buy it you never know the history of a car i personally be kind of learning why somebody selling a three-year-old car what's the reason behind this maybe it was wreck bar flooded or stolen and they all gotta get rid of this car fast always have a mechanic check out any late model car before you buy it someone could buy a new car the next day they could rack it and then try to sell it so you gotta have it checked out t-series says scotty my keyless entry barely works sometimes i have to press many times i lock the doors 2013 ford c-max just take your stupid fob apart and put a new battery in it could easily be there hopefully you've listened to my previous advice i tell people always have at least two good keys at least two two right if you think the key is bad get the other keyless and if that works great you change the battery and the other one that didn't work and then if the other one does work that you have like i do here in the drawer then you'd know okay i have to get a new key mate i'll use the other one i always have at least two good known ones now if it's not that and it's the receiving unit in your vehicle that can cost a fortune so before you do that have the alternator and battery load tested the weak battery weak alternator can also do that start with all that a lot of times it's just a stupid battery in the unit itself maggie c says my 2021 rav4 shocks broke is that normal well it's not normal they shouldn't break that soon i don't know where you live i was watching one of these grand tour on prime video i like those english guys that used to do top gear the new top gear stinks but the old one was great nail left and went to their new show that they got on amazon and grand tour and they went through some place i believe was in africa and those roads were horrendous and if you're driving on crappy roads like that nothing would anything will break right but if you're driving on normal roads no that's not normal it's 20 21 toyota would have to fix them free i mean there's no doubting that unless like you bashed into giant holes and then you bent the rims and broke stuff they're not gonna warranty something that was abused but it isn't normal for those things to break that suit no my toyota worth ninety thousand miles still is the original shocks they worked perfectly fine mr pond says scotty what's a good sub 100 scan tool for japanese cars all right i would say go look at the innova scan tools i-n-n-o-v-a all the auto parts start selling and if they got one that's close to 100 buy it now if there's one that's like 30 bucks more buy the one for 30 bucks more it'll do a lot more in that price range they make pretty good scan tools that can do quite a bit on japanese cars you're going to get a heck of a lot more if you buy their 300 scan tool but you don't want to spend that see what they have in the lower price range because they make good ones in that price range drone production says is a 2015 acura mdx a good luxury mid-size suv it was taken care of yes accident they're well-made vehicles you have to get them test about that that's a seven-year-old high-tech fancy honda hackers are just fancy haunters a lot of technology in those things get it checked out but they can be excellent vehicles customers i have loved i and anybody that really complained about them as long as they change the oil regularly james walker says what's the best product for cleaning up a rusty frame on an old toyota pickup okay well one you got a rust frame on an old pickup it was one of those ones that had the frames it could just be shot and you can forget it if it hasn't rotted the whole way through when you hit it with a hammer it just crunches and goes in first thing you got to do blast it all off then coat it with anti-rust stuff then prime it and then paint it if it's not completely shot you said an old pickup it might be completely shot and then you're just kind of screwed because once the frame goes you could go frame off restoration you got to take the whole vehicle i'll buy another frame that's more money and the vehicle's worth it's not worth doing you got to get rid of the rust first if it's really bad rust they say oh you sprayed this on no it doesn't you got to get the old stuff off sandblasting or sanding or steel wool whatever before you start the process of sealing it you can't seal old rust that's got crumply pieces if you put anything on it it will not work yeah take the heavy rust off first so if you never want to miss another one of my new car repair videos remember to ring that bell you\n"
