Hyundai Santa Fe Mechanical Review

Man, I'm only 2/3 through this video and already I can honestly say that is the best review ever that I've seen, and I've seen them hundreds. Technical details are important to me.

FInally!!! Mechanical review! Best review ever. I wish you did a small add-on about the 2.0 turbo engine. I bought this in 2018 to downgrade my 2007 Santa Fe with 300.000 kilometers to a short-distance family hauler. I hope the new one will be as reliable as the old, I miss the V6 though. By the way dealerships are extremely careless with the oil change panel, losing clips and re-installing it incorrectly.

[@crosses101]

12:53 That's incorrect my friend, the sensor is actually behind the bumper cover and held on by 2 thin aluminum brackets. Now that solid plastic actually protects the radar from incoming debris from the road and if u look either to the left or right of that solid plastic through the honeycomb holes, you will see the radar sensor about 5 inches behind. I hit a cone on the i95 that was capsized on the roadway and the forward collision light came on almost immediately. I checked it out and the radar itself wasn't damaged but it's flimsy bracket was and I had to staighten it in order to fix the malfunction.

[@kens97sto171]

I really like your reviews You're very in depth about the mechanicals on vehicles and I definitely appreciate that. However I kind of find of interesting that almost everything that you pointed out as being sort of a negative... old school, not new tech..etc are things I'm glad they are doing that way. Mechanical water pump, simple easy to fix and inexpensive to replace, old-fashioned vacuum brake booster.. good, it works it always has worked and it rarely fails, and gives better feedback to braking than electro assisted brakes . Having the PCV NOT built into the intake manifold? Why the hell would I WANT that? . Because they eventually plug up and then you've got to take the intake manifold off. VW does this crap but it's in the valve cover, and you have to replace the whole valve cover for $200, or I can go to O'Reilly and buy a $3 PCV. Everything you mentioned or sort of implied was old school and not new technology seems like a good thing to me. Again I'm not criticizing your mechanical aptitude or anything like that I think you did a fantastic job pointing out very important details of the vehicle. I just find it interesting that your take on some of these older technologies seems to be negative when in reality it should be a positive at least in my opinion. But maybe I'm just weird because I tend to keep my cars for 350,000 miles.

[@speedkar99]

I understand your perspective. Watch my Ford Escape and Rav4 mechanical reviews and you'll understand how behind Hyundai is under the hood. I'm simply comparing it to it's competition.

[@VladPayne]

16:02 WTH is that metallic sound? My 3 cyl 1.0 T-GDI has the same rattling exhaust sound and it originates somewhere between the cat and the first resonator. Been crawling underneath the car longer than local cats to find out what the hell is causing this rattle. Mechanics differ in assumptions, some say it is normal for hyundai, others say it's a failing cat or something along those lines. What is your take on it?

[@FUELEDNOVA718]

My '19 Tucson sounds the same and sometimes even worst (have videos on my profile to prove it). The noise has been there since I bought the car and it bothers the hell outta me.

[@VladPayne]

​@@FUELEDNOVA718 found out what it was - turbo wastegate rattle. You can fix it for 50 cents yourself, just buy a spring and tension the arm that goes from the servo to the wastegate. It is located just behind the motor at the top. Very easily accesible, just remove the top beauty cover and insulating foam. Connect one sping end on a rod that supports the plastic cover, the other end on the arm itself. Suggest adding a little of hose rubber to it, a small, mby 3mm hose, so that it would not scratch in time. That wastegate has a spring from the start, but it is just too weak on some turbos and need a bit of help. Ride it till you hit high mileage, then remove the spring, report the wastegate rattle, get new turbo, profit!

I agree with the response that this is a very thorough explanation of engine and vehicle components. And I'm sure this video will help me when I put the new engine in. I am about 3/4 of the way of pulling the motor from my 2015 Sante Fe turbo. And even though we have the software knock sensor service call in (that did not work), we are wondering if Hyundai will honor the class action suite for 1000's and 1000's of their engines than have gone bad do to metal chips left in the manufacturing process and lack of oil from oil pump.

Hey speedkar99, could you do a video on basic vehicle mechanic check, fix/ repair, what each symbol mean, and how to fix it yourself. Examples: • check engine light comes on. • Someone put water/ sugar in your gas tank. • A rear windshield wiper doesn’t work. • A turn signal or light (by light I’ve included head, tail, brake, high beam, fog, low beam, caution & headlight) is out. Now how would a newly beginner mechanic that hasn’t worked on his own car yet do, fix, change/ replace, remove, drain, & repair their own vehicle. Keep up the great videos, you & ChrisFix are literally educating future mechanics (& beginner mechanics) on vehicle service DIY.

Great job as usual. Enjoy your extensive reviews like these. Toyota use established designs for decades too. There’s a good reason.

Toyota used vacuum pumps on their non turbo engines

[@joeb2588]

I believe the 2.4 was redesigned not to long ago. Ok, I see now. Yes, it wasn't a problem with the motor. Hyundai, i believe in the Alabama plant, decided to use water jets to debur the metal shavings from the parts. Well, it didnt work. So they had to go back to a more mechanical way or removing the particles.

[@speedkar99]

They fixed the issue from 2018 onwards I believe. This car seems simple and easy to fix and might hold up long term but there are some places where they did cut corners.
