2004 Infiniti FX35 ABS problem?

[hardybj]

My FX35 AWD 6cyl will seemingly have the ABS kick on at low speeds. I will be leaving my development and without applying the brakes at all and the car will shudder as if the ABS pumps the brakes. Or maybe it could be the traction control somehow? Anyways the dealer didn't believe the problem which only happened about 1x a month. I had to drive it directly to dealer after it happened again since numerous warning light stayed on until I shut the car off. Apparently no code faults could be read at prior visits. My dealer decided it was my ABS module and replaced it. Anyways it happened again last week and I drove directly to the dealer with the warning ights on. Of course they decided to do extra work supposedly missed at the 30k checkup (car now at 33k) rotation, rear pads etc. to pad the bill, but they said they simply cleaned the calipers and sensors and are returning the car tonight. I can't believe that at my 5 prior visits including the time they changed the ABS module that they declined to clean the sensors. Has anyone seen any issues like this? Thanks in advance for any help!

Haven't heard about this particular problem. I do know that traction control often uses the brake system ( applies brake pressure when wheel slip is detected )

Issues like this? From the dealer, yes. I can and often see anything from a dealer. Don't get me wrong, I am sure there are at least a few good ones out there but unfortunately, the incentive is not to fix your car but throw as many parts on it as they can before they fix it.
As for your problem, which lights exactly are the ones that come on when you are having the problem? Transman

Try to keep an eye on the road conditions when the lights come on. It may just be your traction control at work. Post back with more info and we will try to help. Greasemonkey

Hi Transman-
The lights that stay on are the SLIP and VDC OFF

Hi GreaseMonkey-
The conditions are usually dry and roads clean of debris. No reason for traction control.

Thank you for looking into my problem-

This one is probably not going to be solved here, I'm afraid. There are too many things involved in this circuit. Everything from the brake fluid level sensor to the wheel speed sensors, including the tpms (tire pressure sensors), then you can add a Yaw rate, side & deceleration G force sensor. Add to this mix the fact that it is intermittent and no codes. I can understand why the dealer might have a problem solving this one. You may just have to wait and see if a TSB pops up. There is a recall on the caliper bolts not being tight enough though. Good luck and post any other symptoms that you may feel or notice, Transman

I JUST picked up my 2005 FX35 from the dealer today. The ABS module replaced ... within 15 miles of the dealer, the same problem occurred ... SLIP, VDC Off, ABS lights all came on until the motor was turned off. Along with this, when I apply the brakes, I feel a "slipping", like something is loose or not catching. The slipping feeling/sound, is an intermittent issue, happens maybe every 3rd time brakes are applied, speed not a factor. It doesnt seem to matter if I'm going 50 and braking, or 20 and braking, it just does it sometimes.

Vehicle has 31k miles on it, road conditions dry when problem started, and actually lights came on during highway drive with no braking.

All I can offer is keep returning it back to the dealer. Keep all paperwork from every single visit with any and all notes, just in case you need to lemon law this one. Return it quickly so it will still be fresh in the technician's mind on what he as already done to this vehicle. Post back your results, Transman

This might be a long short, but are the correct tires and wheels on the vehicle? Dealers make their money in aftersale, and wheels are big profit center. The wrong size tire and wheel combo can wreak all kinds of havoc on ABS and traction systems. And the service dept will never admit it... unless YOU were the one who put them on.

The correct size wheel is 18" and the correct tire size is 265/60-18. Bridgestone Potenza RE92A in that size were standard with V rating. Is that what you've got?

I have the 20" upgrade for wheels with stock Goodyear's on them.
The slipping just happened again this past weekend and the
oil was changed yesterday w/ no codes read. I also have a
clanking noise front left wheel at bumps, the dealer told me
they had to tighten a caliper bolt. But after getting off the highway,
I hit a small bump and there was the noise. This is the second
dealer (Warwick, RI) after having issues with Norwood, MA.
I pay through the nose and nothing ever gets fixed.

I wish I could just drop it off for good!

Ok, so mine is going back to the dealer tomorrow ... again. So far, they have changed the abs module, as well as all 4 wheel speed sensors. The lights no longer come on (apparently that was the problem the computer was reading). Still slipping though, even with simple braking.

I also have the 20" upgrades, Goodyears. Still original tires from when truck was bought new. Will check back for updates, and to post as well.

Oh ... supposedly, they will be calling in the Infiniti "fix" team on mine. Unfortunately, the service manager that was handling my repair has been reassigned to the Nissan side (wonder what he did!?). So I will have to remind them of their calling in "fix".

Update:

1 week in the shop, the dealer called in one of their tech specialists. They pulled everything apart, and ended up finding a hairline crack in the front wheel hub. They have replaced both front hubs, as well as 1 abs sensor.
I just picked the truck up this am. So far, so good.
