Replying to: ft20 (Oct 28, 2009 7:31 pm) the sad thing was the rotor and brake issue was the only problem we had with the FX the entire 42 months we had it; if it wasn't for the constant brake/rotor issues I would have bought the FX at the end of the lease rather than return it but it just would have became to expensive to keep a vehicle that had to have all the brake pads replaced and rotors resurfaced at least once a year! one interesting story; I was in the dealership one time having the FX rotors resurfaced and I heard a guy who had a 2007 G35 sedan in for service stating he was having grinding/shimmering in the wheel when applying the brakes; the service advisor comes in and says the mechanic says that the rotors were completely warped beyond resurfacing and he had to have brand new rotors put on the car; if that wasn't bad enough, take a guess how many miles he had on his G35..... 10K MILES!!!!!!!!!!!!!!!!!!!!!!!!!! I don't know how that guy kept his cool but this is just completely unacceptable for a Infiniti product to have to deal with I just pray that Infiniti has finally gotten its act together and fixed these issues with their vehicles because they really do make a great product in regards to performance, luxury styling, and technology and to have it all spoiled with lousy brake pads and rotors is just plain ridiculous

Replying to: smarty666 (Oct 29, 2009 4:45 pm) Infinity is not the only one. I had to replace the rotors and front pads on my 2005 Dodge Dakota PU at around the 12,000 mile mark. If you check out the Chrysler Town and Country thread a bit, you'll see all kinds of stories about pads and rotors having to be replaced every 10,000 miles or so. That performance, or lack thereof, is unacceptable in any vehicle. But, I would expect a lot more from a car like the Infiniti that's being advertised as a performance oriented sports sedan/coupe. |

I am new to the forum and just wanted to say hey and report my findings. I have a Liquid Platinum (Fancy name for light silver I guess) 07 Journey Sedan. I am an avid motorhead from the muscle car era. I must say these cars do put a smile on your face when you squish the long skinny pedal. I have owned several muscle cars starting with a 67 Buick GS400 (I was 17 at that time). I also had a 70 Dodge Challenger and an 83 Capri RS 5.0 liter. I must say though the G35 offline acceleration blows them away. Not to mention the handling, safety and quiet. I have recently installed a JWT dual pop intake system that really helped open up the nasal passages. The intake sound is amazing! I have also added a cheapy SLR chip (they claim 50hp, I am very skeptical about that but did notice a little less lurch in offline acceleration). That alone was worth the $69.00 plus tax. I also just purchased and installed a Boral exhaust system. According to the upgrades and a recent dyno test. I am getting just shy of 400hp at the crank. The beast as I call her sometimes, now runs just about even with stock SRT-8s and some lower end AMGs. The funnest part is that it looks stock other than a Stillen rear spoiler, very unassuming. The sound my car makes now is music. It is amazing. Initially I found the G35 quality great however as I am putting on fairly easy miles on it (well a couple of 130 mph runs on the interstate) I am finding some annoying quirks. 1) There is an off idle stumble that makes it a real challenge to take off from a light smoothly. I read an article way in one of the major car magazines and the test drivers mentioned the exact same thing. They said, "no sweat we talked to Infiniti and they provided a software/firmware update to the ECM and that took care of it. I mentioned this to two different dealers and they said that there is no such thing as an update.. Thanks Infiniti! That's one. 2) So far two key fobs have had to be replaced. Even after heeding the warnings of keeping my cell phone away from the fob. Didn't matter they both died. Replaced under warranty. I should friggin hope so! 3) At 17k miles the gear selector jammed and thus I was unable to take the car out of park. Repaired under warranty as should be. Turned out to be a flaky microswitch. 4) At 21k new tires were needed. I reviewed articles and opted for the Bridgestone Potenza Pole Position RE960s.. The best tire around? Except if you have a G35 Sedan. These made the car so unstable around turns that it was scary. It felt like the butt wanted to pass the nose as soon as you leaned into a turn with any kind of speed. Wheel works stood behind their word after they let me try them for 30 days, they offered new tires and we worked out the difference in price. I now have the Bridgeston Turanza Serenitys which is a brand new design and they grip very well are very quiet and are warrantied for 60k miles. I still feel that the RSAs were a more assuring grip when driven to the limit though. Maybe stiffer sidewalls and softer compound. The Serenitys are a very nice tire as long as you don't push too hard around turns.. Case in point is due to the way the car's suspension is set up it is picky on what kind of tires are installed so buyer beware. Make sure when you get tires that if they feel strange you can get different ones. 5) My biggest dislike though is the quality of some of the interior components. The display for the radio (no nav) is becoming intermittent. Sometimes it won't light unless I shut off the car, wait a sec and then fire her back up. Also the floor mats. At this low of mileage they are almost in need of being replaced jeez louise folks, My wife has a 91 Ford Explorer with over 130k and we still have the originals and they are in great shape. Pityful. Then lets talk about the weird rubbery coated arm rests on the doors. The coating comes off with a hard rub. You barely touch them with a fingernail or heaven forbid it you watch grazes it. It looks terrible. All that neat looking metal flashing is totally overshadowed by the yellowish plastic under that crummy rubber crap. Even the plating on top of the gear shift is wearing away.. This kind of quality for a car well over $30k.. I think is unforgiveable for even a mid grade car let alone an upper scale car. I am working with my dealer. The best they can do is to replace the driver and passenger side with the same crap that will end up needing to be replaced in a couple of years. I was told that the 2009 model has a different covering that avoids this problem. The dealer wants over $500 to replace the four. Huh? This is customer service. A known problem/design flaw that has now been updated but a customer has to pay for their mistake? I can go with a 47 piece aftermarket in just about any finish I want for $300. Yeah it may be fake carbon fiber but it certainly looks better then the scratched up armrests and will resist scratches much better than the stockers.. 6) Lastly, I too have noticed a bit of a shimmy when under fairly hard braking. Thus, the chances are that the rotors are slowly beginning to warp. Looks like I will be calling Stillen and going with one of their brake systems as I don't have much confidence in what Infiniti provides. Sorry for being so long winded but I had alot to say and share. Thanks for listening and I look forward to more chats with you all. I hope that you all have a great upcoming Holiday season!

Replying to: Mr_Shiftright (Nov 15, 2009 6:29 pm) I took my car in at 8K mile oil change service with a note for them to check the light jitter I felt when braking. It was of course warped rotors. They machined, and it drove fine until now. Well as expected the vibration kicked in again at high speed, and was felt more today. I called and will be taking it in tomorrow to the dealer. I better not be charged for this reoccuring thing with so little miles. Wonder if the above mentioned TSB covers 2008s? I assume the brakes did not change from 07-08. As they keep on maching more off the rotors, I assume they get weaker (thinner) with time and would tend to warp even more often now? Do I have a case for them to replace the brakes at their cost rather than this machining crap that will probably bring the problem back again?

Replying to: Mr_Shiftright (Nov 25, 2009 8:36 am) Here is an update though that might interest all. Just got the call from the Ann Arbor, MI dealer. The car is fixed under warranty but they did shed some light that I hope anyone here can share thoughts on... They claim that a new bulletin that came out (TSB?) indicates that the water shield on the brakes is undersized and allows more water to hit the hot rotors than should and thus cause the warping. So he tells me they replaced them with larger shields, per the bulletin, and I should not have the problem re-occur. Makes sense but Im a bit skeptical. Time will tell I guess if this will resolve the issue If anyone else heard about this "bulletin", please share thoughts
