I would like to see how many problems other people have with their cars once they hit 100k miles.
Just list what you have replaced due to failure, not maintenance items.
I have around 96k, and so far i replaced:

-4 rotors ( warped very early)
-muffler (old one rusted at 65k)
-main cat ( at 65k)
-6 iginition coils
-several O2 sensors
-alternator
-shocks (old ones blown)
-rear brake piston
-maf

less miles than that (77,000) same problems except the shocks and coils, car seems fine, not sure how to tell if coils are bad.

85k - Replaced Coils + Spark plugs

91k - Replaced MAF

105k - Front headlight wiring fried.

140k - CEL for the front precat--covered CEL with black tape

149k - Some phantom starting problem...and to top it off I need new front rotors and pads.

i have replaced a cat or 2 and a O2 sensor and all brake pads and rotors so far and i have 99k but no alternator yet.

i was wondering what you bought for a new alternator and how much you payed for it

At 71k right now.

- Transmission (auto)
- Fuel tank
- Lower control arm steering limiter caps
- 2 MAFs
- Belt tensioner
- 1 factory head unit
- Transmission shifter assy
- 2 O2 sensors
- Transverse links (duh)
- Front grille nissan emblem fell off
- Spark plug tube seals (in valve covers)
- Thermostat

i'm at 67k
-rotors (changed yearly)
- transmission
- have ses light for front sensor.. dont know which one it is
- front axles
- rear hubs
- engine mounts

-2 rotors (warped)
-6 iginition coils
-alternator
-shocks (just for the looks of the drop old ones in great condition)
-maf ( just to update to a new one.. not needed)

nothing else.. my car is GOOD!!!

@79k
- rotors
- passenger side wheel bearing
- passenger side wheel hub

Other than those, everything's in working order.

Both front wheel bearings - of course
new maf
AC unit in the console
New front rotors - backs might need changing too / my car shakes badly at hi speeds
New rear caliper
A real stereo

same miles as you, replaced brakes, rotors, tires, MAF, ignition coils (6), Trans (partial repair auto), spark plugs, and headlight bulbs.

EDIT: oh yeah, 1 seat heater element (driver), 2 heat seater switches (both driver)

81,000

6 -coils
2 -maf
1 -pass. side wheel bearing
1 -starter
1set -warped rotors
1 -heat element for drivers seat

2002 Auto 94k

Maf
02 sensor
Tranny is Slipping

107,ish right now....

so far have replaced:

all 6 coils
front axles
all 4 rotors (twice)
clutch master cylinder
air conditioner

126K

3 MAF's
All 6 Coils
All 4 rotors and pads 3 times
Rear calipers
SOON: Washer fluid motor

135K miles

4th clutch now- 1st smoked by exfiance learning stick, 2 ACTs which had failed PPlates.
6th MAF now- 1st 4 got killed in very short life, few of em lasted just a week.
6 coils- not needed but I repleaced them at 60K when doing plugs
4 new rear wheel bearings- and they are howling again now
3 sets of OEM front rotors- thanks to OEM Nissan pads- rears are still original at 135
2 rear calipers- both froze not too long ago- got new ones hanging here.
1 slave cylinder
1 pass side axle
1 transrebuild by me at 68K miles- 4th gear blew apart
1 trans repleaced at 100K miles, nothing wrong but my Xtended warranty was runing out- they wouldn't cover my 4th gear blown up thou
ES bushings- all around to repleace worn OEM rubber bushings
3 drive belt tensioners- bearings got too noisy
1 VIAS intake which broke beyond repair- done at the same time as the tranny, 100K.
1 O2 sensor, wires got chewed up while offroading durring camping trip.

Still loving it

@114k miles
- rotors numerous times.
-ruseted cat back.
-coils
-maf, once.
-alternator @ 70k
-VIAS fixed myself at 99k
-Clutch @ 109k
-Starter - yesterday
-Bottom seat drivers' heater - still not fixed.
-Chassis Control Unit acting up once in a while.
- bent rim

Thats about it, still on original shocks. I think I want a truck. those Tacoma's look pretty nice.

I'm at 82K... Replacement of faulty:
- rotors front/back
- alternator
- belt tensioner
- both pre-cat O2s
- rusted exhaust between muffler and B-pipe
- VIAS
- fuel filter
- repainted (many chips) roof, hood, bumper...

something like garaging ur car/weather and ur driving habits cause a big difference in certain things.

@140k miles
- spark plugs
- left side marker blub



EDIT:

Driven hard on daily basis but well taken care of

wow, thats lucky.
all these things makes maximas seem not all that reliable, i guess my problems have been very similar to everyone elses.

Reliable... Rotors, alternators, coils, MAF, O2s are all minor problems IMO. These parts are standard maintenace items in my books. All cars are the same way, they all have their weaknesses and it is their strengths that set them apart. This is an 8th car I owned (1st Nissan) and I can tell you that it is slightly better in terms of reliability than all others I had so far...

Compared to 2 Toyotas I owned in the past i would say the Maxima is not reliable. I guess thats the payoff, boring reliable Toyota versus a more exciting maxima which is less reliable.

And all this talk of how much more reliable the 5 gen is over the 5.5 gen

Hehe, I like the comment Though they are mostly getting made outside of Japan nowadays and as such have become of lower quality than they used to be...

2K Maxima GXE @ 90K miles:

1. Replaced 6 ignition coils in 2001. They were replaced with 2K1 coils which also went bad, so in all, I've bought 12 ignition coils.
2. Two O2 sensors

Maintenance:
1. Front brake pads, (had rotors resurfaced. I've had no warpage problems)
2. Drive belt and spark plugs at 75K

-I Need to replace my struts...Everything else has run like a champ. One thing would be to note that Nissan manual trannies are MUCH better and more reliable than their auto's

I hope that taught you a valuable lesson never to put in used electrical parts.

i have 130k miles on my car..
things that were replaced along the way

auto tranny was toasted, swapped to 5speed.
transmission control module needed to be updated.
AC fan blower replaced twice
rotors warped-switched to 300zx then to AP big brakes
6 coils replaced
strut bearings went bad switched to JIC flt a2
ecu needed to be reflashed to clear the p0420 code (3way cat failure)

that's pretty much all i can think of for now

@ 135K..

2 HUBS & bearings each side
both axles
alternator
starter
battery
6 coils
updated MAF
bad injector harness
depleated left rear caliper..why does this happen so often it seems ?

2K Max with 77K

- 6 coils (2 went bad), replaced remaining 4 along with plugs
- MAF, probably need a second one as of today (just got cel this morning, but same symptoms as before)
- new rotors
- transmission control module
- exhaust from cat back
- starter (not yet replaced - regreased once a few years ago, starting to whine again in cold weather)
- bad heater switch for driver's seat (bulb)
- VIAS, have yet to replace but I'm pretty sure it's shot

too many problems for me.

123k 2000 SE

6 ignition coils
Spark plugs
MAF
Thermostat
Radiator Fan
Alternator and Battery (Both died at same time)
AC Blower Motor


So about $1000 parts for 123k miles... isn't bad.
Although I think I'm about due for rotors, pads, and shocks.

2000 Max SE 5SPD Green with 156k (fully loaded/nogps)
- 2nd Clutch
- A/C Compressor
- Cup holder sliding cover bracket broke (?)

No coil issues, maybe previous owner got it. My driving is nothing but all highway hence the clutch has been lasting more than 60k each time. Never warped any discs either. I don't know if too much babying and never over 4k rpm helps but no problems ever.

1996 Max GLE Black Auto with 130k (fully loaded/nogps)
- No engine or transmission trouble ever
- Regular brake changes
- Passenger side wheel hub/bearing (slipped/hit curb in snow)
- Rear Spoiler holes started rusting and made the trunk messy. Got a new one and had the spoiler drilled holes water proofed with extra rubber sealants.

2001 SE - 125K
I'm feelin' lucky after seeing some of the other posts!
4 rotors
IACV/TB (after I cleaned the TB)
Heater Blower Motor
Fan Amp
P0420 programming fix

Just got another P0420 - I guess maybe an O2 sensor or the cat is going.

138k:
(1) main cat
(1) transmission (auto)
(4) fog light housings
(134,522) quarts of oil
(1) interior blower assembly
(1) temp. control cluster (fixed by me)
(1) set of rotors

Ooops! Forgot 3 rear wheel bearings

2k SE 5sp @105k miles
- One MAF
- One O2
- Sun visor thing broke off so I superglued it.
- Currently have CEL light on that I've been ignoring for the past 3 years. It just needs ECU update but I refuse to pay Ni$$an to do it.
- My battery died this summer but I brought it back to life by adding lots of water. So good so far...

just hit 128K this morning.

Replaced.

MAF @ 112
Rotors @ 39 and 90 (put brembos)
#3 cylinder coil 121K


thats about it.

100k

Front right wheel Bearing
Battery (5 years old)
Brakes Warping replaced with 300zx/Cobra BBK, and Power Slots in the rear

can any experts explain why the wheel bearings go bad so often?

My 2k maxima....

5spd tranny @ 59k - replaced under warranty
rotors @ 65k
coils @91k
immobilizer @ 96k- replaced under goodwill warranty
5spd tranny @ 100,080

Wheel bearings go bad from either abuse or curb hits or very very crappy road. This is only true for most of the cases but not all. As the time passes, it may create a play which you can feel by simply rotating the wheel and a rubbing noise will start to get louder. However, if you have alloy wheels, they usually will take most of the force and in some cases will be the first to break/crack before the hub/bearing...
