2003 Infiniti G35: grinding or squealing brakes

Filed May 2, 2007 · Brakes · 1 miles · IN

My 2003 infiniti g35 has an unsafe brake system. Since it was new and before 24,000 miles, I have had the brake pads and rotors replaced 3 times. They wear out so fast that it is difficult to know when they are unsafe. They always have squeaked loudly, even when new so that is not an indicator. Infiniti stopped putting this brake system in the g35 6 months after manufacturing started and they gave a 3 year warranty on the brakes of these cars, so they knew they had a problem. They will do nothing to fix this.

I purchased my 2003 infiniti g35 in october 2003. I only have 19,000 miles on my car and the brakes have been squeaking loudly since about 13,0000 miles. I have mentioned this to the service dept at the dealership on 2 or 3 occasions when I've taken my car in for service and was told this is normal. I've bought several cars and never have I heard that the breaks squeaking unbearably was normal. They told me to wait until I bring my car in for service again and if the brakes are even more worn down they might see what they can do. I don't know if the car is even safe to drive. Do the breaks have to totally go out and I run into the back of someone before I can get them fixed under warranty??? I have a 95 mustang and it sounds better than my 2003 infiniti. I don't want to pay 30,000 for a car that squeeks as if I'm driving an old beat up lemon. Help! Kdj.

Constant brake noise - how am I supposed to know when my brakes need replacing if they are always squeaking - that's usually a sign, but in this case the only sign will be when I crash into something or someone because they stop working.

I first replaced the front brakes and rotors (which were warped) on my 2003 infiniti g35 coupe at 14,000 miles after they had been squealing since approximately 5,000 miles. Before the replacement I had to add brake fluid, which should not occur on a new car. At 17,000 miles I have just replaced my rear brakes. Infiniti obviously is aware of this problem because all brake repairs are free until 36,000 miles. But what about after that and why are they repairing one defective part with another defective part? I am truly concerned about this issue and the safety of my vehicle and its stopping capabilities. I know other owners have the same problems with the brakes and I feel something must be done about this before a catastrophe occurs.

Noticing that brakes make a squealing sound when used and dont stop as well as they used to.

Drivers side seat rocks on braking/turning. I had the car in for an oil change and asked about the seat. The dealer told me they replaced a part in the seat. It helps somewhat but there is still too much play in the drivers seat. It makes you wonder if the seat is actually secured to the car properly, and also in the event of a crash, would the seat hold up appropriately? Also the brakes are squealing at 10,000 miles. Actually, they've been squealing for the last 4,000 miles. They are starting to make a grinding noise as well sometimes. I haven't been to the dealer about this yet, but it is a concern that the brakes could fail. I previuosly had an expedition and had problems with those brakes as well, but would normally get 20,000 to 25,000 miles out of them.

Almost 99% of the time when I roll my g35 within 10 MPH I hear a crackling or grinding noise (like fan just started) and a "vibration" would transfer from the brake to my foot. Fter troubleshooting (shut down all sound device including AC/fan) and researching the owner's manual, it stated what I described above is normal. It's a self-diagnostic feature on ABS system when the car is moving slow. The noise is kinda loud and noticeable. Is it the norm for all ABS sytems by other manufacturers??

At 9.5k service (3rd), car had slight pulsing in the brakes. Dealer confirmed warped rotors and machined. Estimated remaining pad life only about 50%. Car and brakes have been well maintained in mainly city driving. This is the fastest wear I have seen on any car I have owned in 35 years including numerous performance cars. Dealer acknowledges many complaints for premature brake wear. This has also been a reccuring topic on infiniti web forums. Dealer indicated infiniti used to cover this as warranty but is now balking at replacement under the guise these are "high performance" brakes and normal wear and tear. With the potential for ultra short brake life, some consumers may not believe the brake wear indicator squeal and not get the brakes checked in time to prevent failure. This could turn into a long term safety issue. This also maybe due to an unrecognized interaction with the stability control, electronic brake assistance and traction control leading to higher brake stresses and short life. This should be looked at for a techical service bulletin and watched as a long term safety issue as the cars age.

I purchased my 2003 infiniti g35 in august 2002. When I first purchased my vehicle I noticed a lot of brake dust on my front brakes. I informed the service dept of the dealership where I bought the vehicle and was told this is normal. About a month later I began hearing a squealing sound when I applied the brakes, I contacted the dealership again and I was told that this was normal. The dealer even began to read me an article/publication suggesting that this was because these were high performance brakes. Needless to say after back and forth with this dealer and infiniti for over 4 months, to no avail I left the issue alone. Now 6 months later, I require new front brakes at only 19,000 miles.
