Hello AFC, this is my first post. I'm excited to be a part of the community! Very helpful and relieving to know that there's a place like this for a car like the Aztek.

I drive a 2002 AWD Aztek with 127k miles on it, and I want to take it on a trip from Boston to Florida. Before I do, I want to address two issues I've been having, and hopefully get some feedback, because I'd like to make it there in one piece!

1) Highway stutter
At about 45-60mph, my Aztek will stutter/chug. It feels like it's happening in the middle rear of the vehicle. This will sometimes happen when I'm driving in residential areas as well - even at 30mph! The stutter will vary from faint to violent, sometimes shaking the whole vehicle with its chugs. Does anybody have an idea of what could be causing this?

2) ABS problem
This has only begun to happen in the past week, but when I'm driving slowly or coming to a stop, I can feel my brakes lock up/push against my foot and make a grinding noise. It makes the car unable to come to a complete stop, but only for a second because a pump on the brakes temporarily fixes it. I've asked friends who have some knowledge on vehicles, and they said it was an ABS issue. Could anybody confirm this or add to it?

3) Grinding noise when turning wheel
This one isn't too severe, just something minor that has begun to bother me. Turning my wheel to the left or right causes a slight grinding noise.

Thanks AFC!

I too am going on a long road trip in my 2001 AZTEK - it has 106,000 and runs well, expect the same thing as your #2 is happening.  Hopefully, this is nothing major as I'm trying to decide to keep my Aztek or if it's time to trade it in.  Love it - but when is it time to give it up.  How many miles can you drive this car without starting to spend some major money on it.  Please advise!

2003 Gold FWD Aztek - aka "The Warthog"

I've been having similar ABS problems for a while now with my 2003 Aztek FWD.  It has just over 120,000 miles.  On the Aztek, the ABS sensors are built into the wheel hubs.  I am now in the process of replacing the rear hub (wheel bearing) assemblies.  I replaced the rear passenger side one yesterday.  I'll be replacing the rear driver side one tomorrow.  I have a spare front hub assembly that I'll swap in if changing out the rears doesn't fix it. 

To properly diagnose what your problem is you need a pro type scan tool that can talk to the ABS system to read the trouble codes.  I've tried using the Torque app on my Android phone and it isn't able to read ABS codes (only engine related codes).   I've heard similar things about the scanners used at Autozone and AdvanceAuto (but I can't confirm that).   You might be able to get a good indy shop to read them for you without charging you.  I'm certain a dealer can do it, but I am sure they'll charge you for doing it.   But it might be worth it to find out what the problem is.

Hi everyone!

fpazyra, welcome!

This may be late but... 1) my guess is that the drive shaft(s) & or front bearing may do this.
                                          2) our abs light has been on for 2 years now, but only pulsing sometimes, when very slow braking.
                                          3)definitely a bearing, (see #1)

sassielass, Our 02 had LIM & heads done at 180K in 2013, & front axle & bearing august 2016 at 210k. We use it a lot but not for long haul trips.

Follow up...

After changing my rear wheel hubs I still had the ABS problem so I was pretty sure the problem was with one of the front hubs.  While inspecting the front hubs I discovered that the driver side outer CV boot had failed, and had sprayed CV grease all over everything.  I replaced the axle and while I had it off, I also replaced the wheel hub assembly.  That fixed my ABS problem.
