You basically have two options. As a former Infiniti service advisor I can tell you that we probably replaced 10 radios a month. Depending on the radio it is either manufactured by Clarion or Panasonic. You can either try to find one at a salvage yard as cheap as possible, or take it to a radio repair shop that specializes in factory car radios. We used to have a local shop who would take the radio out diagnose it and tell you what it would cost to fix it for like 40.00. Unfortunately, there isn't a whole lot you can do. It's likely not the laser but the mechanism that shuffles the cds. 

go to service centre most electrical these days can be fix in 15mins by a computer plug in

It is most definitely the seat slide motor. Most infiniti drivers seats have three different motors. I30, I35's and QX4's all had problems with the seat slide motors. You can tap on the slide motor which is under the front of the seat and it will probably work for a little while, but it WILL stop working completely. There was actually a Technical Service Bulletin regarding this issue because there were so many vehicles that had this problem. I hate to see that guy waste money trying to get a circuit board rebuilt that absolutely will not solve the problem. 

you must take it back., check the oil n water first, they have to accomedate you its the law

call into service centre to re configer computer

There are only to Catalysts monitored by the ECM. There is a wide pipe near the front of the exhaust system that looks like it houses a catalyst, but it doesn't. Look for the rear O2 sensor, that is where the catalyst is. If the bolts that hold it on are not badly rusted, and depending on your mechanical aptitude you could replace them, otherwise take it to a shop. Have you checked the warranty coverage with the dealership?

The squeal is usually the tell tales that make a noise when the front or rear disk pads are worn to where they need replacing. However, with drum brakes, that is an indication of totally worn out shoes, or a broken part. STOP driving the car, go to a mechanic (or friend) and have them checked.

The can can't run. Why need to shift...?If you want to shift anyway. Be careful if down or up hill the car will roll.Here if need to shift away:-Put key in ignition, turn to start, but do not start.Now apply brake then shift.Mai Lor

I had the same issue with mine,and I went to the parts store and bought the best spark plugs and new plug wires and after I installed them it ran like new.

limited info generic answer no by-pass or hotwire thats movies -what is happening is vehicle turning over no start --no turn over--any dash lights [trouble ] on have vehicle scanned --check and examine key and ignition for failure

Look for a failing Crank sensor and/or the cam position sensor. A diagnostic test will tell you for sure.

The knock sensor is on the cylinder block. Concealed from sight because of the intake manifold.

Have the exhaust flow tested for a clogged catalytic converter, and have the fuel injectors bench flowed and cleaned.
