2. Kind of the road

3. Thanks for your videos 👍

4. Turn off trax

5. 2007 4runner. My exhaust manifold has just started to leak. I can hear it. And sunroof leaks terribly. Clear gorilla taped on top. Doesn't leak anymore 😅. Other than that it's a good reliable vehicle

6. 06 4Runner sr5. engine check on, air and fuel mixture too lean on bank2 p0174. Not sure what to do next

7. I have a 2004 4Runner 4.7L V8 with 374K miles. All original no major work and runs great. I live in California so rust is not an issue and I have none of those problem except my heater. It has been a while since I ran but I think it made the sound she describes. Only cool air flows out of the passenger side. Not sure what the problem is.

8. The main problem you’re having with that car is salted roads.

9. Thank God I live in Texas and I have a V8 in my 2005 model.

10. Mine is a Tennessee resident. A 2004 SR5. No frame or manifold rust, only have 93,000 on it.
    
    Dashboard recall, Toyota begrudgingly agreed to issue a recall after user groups and complaints kept rolling in. Yet Toyota half assed it sent out a first notification stating inventory would take time, then totally went silent. So the deadline passed and I missed the cutoff. Will have to order a dash shell as the cracks are becoming larger. Toyota whiffed on this dash material huge.
    
    Inner 12V 120W charge port also will burn out, it is about $1,000 fix apparently

11. This was a damn good video – thank you!!

12. Glad I live in west Texas so I don't have to worry about corrosion like that. Even when I lived in Seattle, cars/trucks didn't look like that. Salt kills. Kinda feel sorry for folks who live in the rust belt and work on their own vehicles.

13. I just traded in my 2007 4Runner and traded up for a new 2023 4Runner limited because my last 4Runner was a reliable car. Of course at being 16 yrs old with 172,000 miles, the only major issue I had with it was a rusty back hatch. My new 4Runner has been rust proofed and will be updated with rust proofing yearly to protect my investment. Love the 4Runners for all season and all terrain driving.

14. What part of the country? Rust caused by winter salted roads?

15. Don't go to road salt

16. I have one 225,000 miles, not problem. Remember maintenance is everything

17. That’s a pretty rusted one

18. Evaporator cores leak freon. Pretty common on these. Good amount of work to get to them too. I've replaced more evaporator cores than relays.

19. Got scammed and bought a 2004 sr5 v6 with 230k miles for $5k few years back. Ended up finding that it ate a cup of coolant every few weeks(even a trained mechanic would have trouble finding this leak). One night accidentally didn't tighten radiator cap enough from refill and wife drove it till it overheated the next day, would barely even turn over now. Well, ended up doing the job myself in a week in the yard, milled heads to .003 and oem gasket set. 700$. I also did an entire valve train job for bucket clearance which I probably saved 2k on just doing myself(not for the impatient). I thought the HG was a rare occurrence but the more I go online I see more and more instances. Car has 270k now and haven't lost 1 drop of coolant, no oil consumption. I wouldnt have done this type of thing with any other car though, I did my research and found the HG issue wasn't detrimental in early stages with this engine. Dont buy the v6 with more than 200k if you don't want to deal with it. Even so, its not like its even a 10%chance so do what you feel 😁

20. If the 4Runner turns over but doesn't start, it may be the transponder in the key stopped communicating. That doesn't happen often with genuine Toyota keys, but it happened to me after a month with a key that I bought on Amazon. It gradually stopped working. Probably frequency drift in the transponder that knocked it off frequency.

21. Prevent frame corrosion. Spray the entire undercarriage (not brake rotors/pads or exhaust) with Surface Shield or a similar lanolin based anti-corrosion coating. Spray inside and outside of the box frame to prevent it from rotting from the inside out. Reapply next year and touch it up every other year after that. Surface Shield doesn't dry or harden so it can always flow to cover the frame, but it does thicken to make a coating that doesn't chip away and water can't get under it unlike paint, epoxy or rubber coatings.

22. Wow they are really scraping at the bottom of the barrel with this ac problem being a "problem" haha. Good video otherwise!

23. More appropriate title: “Top 5 problems when you drive your 4Runner on salted roads and the associated conditions”. I’ve seen none of these issues on my 2003 with 231,000 miles on it here in Florida.

24. I’m shocked about the problems you mentioned on the 4 runner. I have 685k miles no issues

25. I really like this lady, could do more videos with her. She explains everything well and somehow fun

26. Trunk and add actuator 4×4

27. My transfer case module just started leaking 🙁

28. Thank you very much, it is obvious how knowledgeable you are. Keep up the good work!

29. Hi can you please say something about highlandercars my is 2003 y I’m very happy good car so far ❤

30. Tell me about the p0420 code and is it worth the risk ?

31. change my turn signal switch on my 04 4runner v6 and dash lights it comes on now and then. what else to look for?

32. I got one with 144k and now I’ve got 225k. Other than maintenance in that time I’ve replaced the valve cover gaskets, tensioner pulley, idler pulleys, Lower control arms, wheel bearing. A huge issue is seized calipers. I’ve had to replace all those. Frame has almost no rust for me thankfully. But I need a new power steering rack (replaced by previous owner at 120k) struts, shocks and upper/lower ball joints, new rear calipers.

33. Leave it to a woman mechanic not to specify which engine she’s talking about 🤦🏼‍♀️😬

34. 2003-2004 v6 had headgasket isssue
