Had to have the rear window replaced under warranty in my 2018. Wasn’t sealed properly from the factory. Other than that, neither of my Frontiers has had any “build quality” issues. I’ve got ~140,000 miles between the two.

 

ICC TSB Fix and a door lock solenoid replaced. Both under warranty.

And I have an intermittent issue with the driver side blindspot monitor activating when no other vehicles (or objects) are in site. Only happens when I have my camper attached.

 

Interesting to see your post. New 2024 SV Hardbody 4x4. I've had it for a few weeks and in preparation for a winter trip to the south, hooked up my 17' AFrame PopUp for a test tow.

I noticed the same thing with the BSM/W when changing lanes, or making a turn, in my case it was right turns, but that's mostly what I made on my trip. I chalk it up to being normal. I'll further test using the tow mode button to see if BSM/W acts differently, but my trailer is about 2400lbs loaded, so tow mode didn't seem necessary (truck handled acceleration fine without the need for the tow mode increased shift rpms)

 

I've literally never had a noteworthy issue with any of my Nissans ever, all bought new.

My 2022 Frontier went to the dealer once for a new clockspring about 4 months into ownership, it was making a faint rubbing sound in very cold weather.

My 2015 Nismo RS has literally never had an issue, at 80k miles now, and I drive it pretty spiritedly as intended and it's liberally modded. It's put together so well and everything is overbuilt and solid. Such a good car.

My outgoing 2012 Xterra had to have the catalytic converter changed under warranty about 18 months into ownership. It's probably still on the road today.

My old 2007 Frontier never had any issues, radiator was changed after a deer strike to avoid SMOD. It's probably still on the road today.

 

Had a problem with the 7 pin wiring that took longer to resolve than it should have. Otherwise, only random door locking and an under dash noise possibly HVAC related. I've decided to just live with these. Initial quality seems about the same as the F150s I had previously.

 

Going on almost 2yrs with my used 2019 SV CC...only oil changes....new battery because it was 4 yrs old...front alignment just because

 

I'm on my 4th rear window. The previous 3 had the slider and they all leaked. Dealer/Nissan finally caved in and gave me the solid one piece, which is what I wanted from the beginning.

Rear dif cover rusted out and got replaced under warranty.

I'm on my 3rd radio/head unit because the previous ones would reboot randomly and they had Bluetooth issues. The 3rd one is now having issues, too. Yesterday morning, the radio was dead. It had no power. I tried holding the power button to reset it, but it didn't work. When I put the truck in reverse, then the radio woke up. It's never done that before. That's a new glitch.

Back up camera got replaced under warranty.

 

Used 2017 I acquired:

Driver's side valve cover leaked at 27,000 miles. Replaced under warranty, kept leaking. I replaced it myself and it's fine now.

HVAC blower motor died at 30,000 miles. I installed a new one from AutoZone and works fine, if a bit loud compared to OEM.

Rear differential cover leaked at 27,000 miles. Replaced under warranty. Leaked again, replaced at my cost. Leaked again, I replaced it myself and it's fine now.

AC condensation duct got clogged at 30,000 miles and would spill water on the passenger foot well. I unclogged it myself and it's good now.

Edit: Forgot that I replaced the serpentine belt, tensioner, and idler pulley around 40,000 miles or something. It had been squealing and I think it was due to sloppy oil changes by dealer techs splashing oil all over the engine every time they changed the oil. Exact mileage is in a thread here somewhere

Consumables like batteries and tires don't get included.

 

'00 XE 4x2 2.4/5-sp manual bought used in '05 w/ 33K on it. Used as a work truck/daily driver hauling ~600lbs. Alternator went out around 45-50K miles. That was about it as far as any unscheduled maintenance until I sold it to a family member in '15 w/ 185K on it. Replaced the factory cat-back exhaust system for him at Midas as a kind gesture as I could occasionally detect a whiff in the cab. The muffler had some holes from corrosion, but was still quiet.
21-22 MPG consisting of 2/3 city and 1/3 interstate miles. Recorded 26 MPG once while doing a little over 80 mph the whole way.

'15 SV 4x2 4.0/6-sp manual factory ordered. Coolant thermostat went out at 38K which I had to replace on my dime due to being just barely out of warranty. That's it. Still on factory brakes at 112K - and it's also my work truck/daily driver that hauls ~600lbs of cargo most of the time.
17.5-17.7 MPG consisting of 2/3 city and 1/3 interstates miles. Achieved 21.7 MPG once while traveling 60-65 mph.

 

2014 king Cab SV bought new. In ten years had zero issues. I bought the parts for the axle vent mod but never installed it.
That reliability was one of my main reasons for replacing it with a 2024 this year. Maybe I'll do that mod now!

 

2014 Pro-4X currently at 257K. Only replaced the heater core inlet and outlet hoses due to broccoli. Everything else has been PMs. Did have a fairly sizeable rear diff cover leak that was fixed under warranty. Will be doing trans, transfer and front diff fluids this weekend.

 

This is my second Frontier, 2006 & 2016. Never had a warranty claim; however, a careless driver did take the front bumper cover off the 2016. (Currently 60,000 mi) Replaced with Coastal Off-Road steel bumper, careless drivers are not so much of a problem now.

 

My ‘20, purchased almost 4 years ago has only had basic maintenance, brakes, new tires, a battery and oil changes. I think it’s got 38,000 miles. Has had only the parking pawl recall fix. I would say this is one of the more reliable cars I’ve owned. My ‘17 Outback was as good. My ‘11 Forester had heavy oil usage that was common to that new engine that year. The 20/21 MY Frontiers missed out on the redesign for ‘22, so has fewer things to fail, is why I got this model.

 

Gtreat thread.
2017 Pro-4x Crew Cab - 52,000 miles, bought in 2018 with 4000 miles. Was rebuilt title/theft recovery with only damage to front and rear bumpers.

35,000 miles: Replaced thermostat with OEM as it ran cool (185°F) and took a long time to warm up in winter. OEM replacement runs hotter (205°F) but still takes a while to warm in winter, just a 4.0L quirk.

45,000 miles: HVAC blower motor died in 100°F August. 🥵 Replaced with Amazon unit (fast shipping) and still working fine, like @AzureApe a little louder than OEM but ok.

47,000 miles: serpentine belt tensioner started squeaking and bearing felt rough-replaced it and the belt with Gates units.

All drivetrain oils changed at 32k. Tires at 34k. Zero other issues, been a fantastic truck.

 

'13 4x4, 110,000 miles. Only mechanical failures have been the driver's side exhaust manifold flange separating @ ~85,000 and the crank sensor failing @ 92,000. Fenders above rear wheels just started rusting this year.

 

 

picked up my 4th Frontier on Monday, a 2025 KC SV, gun metallic. still have the third one, a 2003 CC LB with more than 326,000 miles. Not a single major issue, not one, ever. my first Frontier was a 1999 KC. the second was another KC SE-V6. i expect this new one (the fourth one) to last another 20 years.

 

Congratulations! I just wish/hope they'd stick with NATURALLY-ASPIRATED ENGINES. I hate this new turbo fascination on, well anything unless you're building a Fox body Mustang or something to drag race occasionally...JMO

 

2024 P4X, bought new in November of 23 with about 21,000 on it now.

Only issue is the the rear dome light. I haven't taken it for replacement; I just leave it off.

 

2024 SL, same problem with the rear dome light. The switch at the light is so loose it will not make good contact.

 

23 Pro-4X, bought back in Nov of 23, 17,000+ miles. No issues other than the NTB needed for the cruise control radical downshifting. Driver's side door lock is a little wonky occasionally.

 

2011 SV King Cab 4.0 purchased new. Had to think a while before posting…nope. Nary a problem.
125k miles. Hell, the brake pads haven’t even been replaced. That’s crazy.
Routine maintenance, that’s all.
I come from 45 years in the automotive industry. 19yrs at independent auto parts store, 26yrs a parts advisor at Mercedes Benz. I've seen plenty of crap (not MBZ). These Frontiers are pretty much rock solid, though nothing is perfect.
I just bought a ‘25 SV King Cab and hope it’s as solid as my Gen 2.

EDIT: I just remembered, there were a few times I got the dreaded ABS/VDC/SLIP warning lights on the cluster. Mysteriously went on then just as mysteriously went off. Happened a couple of times a few years ago, but nothing since then (I’ve since sold the truck).

 

I have owned three frontiers from a 2011 SV, then a 2015 Pro-4X and now a 2024 Pro 4X. Only problem I have had is the tailgate power actuator malfunctioned. Replaced under warranty.

 

My uncle still has a 1st gen Frontier he bought new in 1998. 4 cyl, 5 speed, normal ameneties, and has never had the first problem with it in 27 years.

 

This is such an informative thread, thanks for starting it as we all can benefit from these guys who answered that have a wealth of experience and knowledge about Frontiers.

The only thing I can add is that when I was wondering about trading in the Tacoma for one I asked the mechanic that I found to work on my old Bronco what he thought about Frontiers; he and his brother have been in business a long time and when I asked what he knew about Frontiers his answer was "it's a rock solid truck, go for it".

 

Welp. Fluid changes didn't happen because guess who was missing a 10mm hex wrench? Instead of just going out and buying one, my wife (in her infinite wisdom) decided to have me buy another full set from Harbor freight along with a hand pump because she also wanted to buy 3 more of those braun flashlights they have on sale. So now... we wait.

 

2016 Frontier 216k. Owned since new.

130k- EVAP Canister replacement
180k- MAF sensor failed

Everything else is stock.

 

2018 Frontier SV KC 4X4 I bought it brand new and now it’s got about 45,000 miles on it, so far I’ve had to replace the drivers side 02 sensor, change the battery and most recently replace the crank position sensor. It’s got a rattle under the drivers side dash. It’s a metal plate that needs to be glued or something! lol other than that it seems pretty solid. I had a 2002 Tacoma pre runner, a 1999 f-150 4x4, and I think this truck is just as good if not better than both of those!

 

Had a paint issue in the channels that run along the roof. The clear coat cracked, and dirt got in and eventually the clear coat failed and the came off. Less that a couple of years into ownership and the issue was fixed under warranty. Also had a rather annoying interior "squeak" that was a challenge to find, behind the drivers side behind the plastic pannels that a couple of applications of WD40 spray made go away. First application helped locate the issue, the second made it stop completly. That too was a couple of years ago and no recurrance. Other than that everything in the truck that same with it is still there. Only 18K miles however.
