Hey OP there are a lot of great inputs on this thread, however, I don't think any of them directly answer the question you're looking for.
First of all I am the original owner of my 4runner. Purchased in October 2000 and had to wait for it to arrive from Japan. Drove it home with 12 miles on it.
Aside from all of the preventive maintenance and all the other insights from everyone else in this thread here's the skinny.
History From 2000 - 2014
- Since 2000, I have NEVER been left stranded.
- I never had a check engine light.
- Around 2012 or 2013 I had a whoop, whoop, whoop, sound from the drivers side and it turned out to be the rear axle bearing.
- That was all the "unscheduled maintenance" that I had to do
- I've had a 0770 code e-Solenoid for the over-drive in the tranny for about four or five years now. I just keep re-setting it. One day it will crap out on me. (I'm expecting to do a replacement .)
Vehicle was primarily used for coaching (I'm a soccer coach and transport a lot of speed and agility equipment and soccer balls etc with me) camping, utility vehicle for dirt, fertilizer, pvc pipe for sprinklers etc... as I live on acreage, work, and 4WD for the occasional rough winters that we get here in the PNW. Spent most of it's time at trail heads. I did not do any true off-roading. Park and hike.
History From 2014 - Current
- In 2014 I got a knock sensor code with a check engine light.
- No idiot when it comes to wrenching and troubleshooting but this one stifled me.
- That's when I reached out to everyone here on the site.
- Replaced the sensors with OEM the KS code went away.
- I got an intermittent 420 code for catalytic inefficiency and replaced both O2 sensors, MAF, filter etc. It didn't fix it but slowed it down.
- Ended up being somewhere in my exhaust because after I changed my exhaust system last year it never returned. Probably the upstream catalytic converter.
Post lift Issues
- Torn inner CV boot - no surprise there.
- Still resetting the 0770 code every so often
- No codes
- Picking up a bit of pinging every now and then but I think it's just bad gas. Lukas and higher octane and it goes away.
So there's a 16 year snapshot on the reliability of the 3rd gen. I have 350,000 miles. As a coach I've been all over Washington State, out to Boise, California, and Oregon. Just did the WABDR post lift without hesitation. Heading to Az in May for the Overland Expo, Zion, Grand Canyon etc and then plan on doing the OBDR in July.
What you need to do is try and do a side-by-side comparison with apples-to-apples. If you can find an original owner in a 2001 Tahoe, Yukon, Dodge Durango, Ford Explorer, Jeep Cherokee, Jeep Wrangler, Escape and any other SUV in a similar price range that 's where you get a true assessment of the reliability of the vehicle.
Be forewarned - you first have to find one with 350,000 miles on it. good LUCK!
I'll echo what some of the guys have already told you but also add my own .02.
IF I wasn't an original owner I would NOT have bought a 3rd gen to build up for "overlanding" and offroading the way I WANT to. I would have bought an LC. However, it makes absolutely NO sense for me to do that with a great platform already sitting in my garage.
Now if you're wanting to compare reliability with other vehicles different generations then that 's a different story.
Final Thoughts
Read through this forum and DO YOUR PREVENTIVE MAINTENANCE! There are things that go catastrophically bad on this generation with higher mileage and you MUST be proactive! Read, read, read. You will learn a LOT by just reading this forum.
- Transmission failures
- Lower ball joint failures
- Rear axle seals
- Front axle bearings
- Radiator failures
- Steering rack failures
- Torque Converters
- Stuck in 4WD
- Head gaskets and cracked heads
- ABS
Some of those items above WILL leave you stranded and can be costly. There's your homework. Research the above ^^^.
All the other stuff is typical of any old car, bushings, suspension components like ITRE, OTREs, gear oil, filters, fuel pump, bla bla bla.
Unfortunately I have NO OTHER vehicle to compare this one to as I've NEVER kept any of my vehicles longer then a few years. The ones that I've owned did give me problems but never left me stranded.
The scariest time for me was in my 1970 Trans Am making a run after midnight from North Carolina (Stationed in Goldsboro) back home to New York for the weekend. Got stranded on the loop in DC at 0,dark hundred popping open the hood with sandpaper filing the points and gapping to a matchbook. Old school dual ignition, points condenser type folks will know exactly what I'm talking about.
One other time I was left stranded. AMC CJ7 Renegade with a 304 (V-8). Stationed in Tucson. Did some crawling in Mt Lemon, returned and just finished installing a flex fan and a new four core radiator. Ready to hit the tanque verde wash. I was hauling until....whop, whop, whop, bang bang. "What the hell?" Helps to finish the job
before you head out. Forgot to secure the radiator.
Anyway, you won't go wrong, but it's an old rig and you will need to do mtx. If you lift it, expect to do more "unscheduled" maintenance. Hope this sheds a bit of light on the lifetime expectancy of a 3rd gen. Find one with the lowest possible mileage you can get for a reasonable price. Good Luck.
