I have a 2004 Inifinit I35. Recently after driving 20 minutes the car died. I was able to restart it after allowing it to sit for 1/2 hour but it didn't last long. Alternator was checked and I was told it was fine but the battery needed to be replaced. Replaced the battery and after driving 20 minutes the Engine and TCS/Slip light came on

SOURCE: replaced braked pads - now VDC and Slip Lights are on

I would take the car to almost any auto parts store and ask them to check the ODB II computer for codes and to reset the "Check engine light". Get the code that they tell you and it should go a long way to pointing you in the right direction to fixing this problem. It might also be that when you pumped the brakes that you somehow set a code in the computer from the ABS system and now that you have the brakes pumped up and working correctly resetting the Check engine light might fix your problem.

Good luck! Write back with any code you get and I'll see if I can help you figure out what the problem might be.

SOURCE: Check Engine Light on at 64K miles

As a Infiniti Service advisor for 5 years I can tell you a couple of things. First, check your gas cap. Make sure it is tightened past three clicks. The Service engine light only comes on because of emissions related issues. Generally if the gas cap is loose then vapors will seep out of the filler neck and the appropriate pressure inside the fuel cell will not be acheived and the computer will trip the light. If you had recently filled up before the light came on, then after the cap is tightened it may take a day or so to go off on its own. Other than that the next most common cause of the light is the O2 sensor(s). They normally do not completely fail but have hiccups so to speak. Their purpose is to measure the amount of oxygen in the exhaust gas, and if one or more of the sensors measures too much or too little it will cause the light to trip. The computer will automatically adjust the air fuel mixture to compensate for these diffenciencies, so it is best to have it checked and cleared. I would highly recommend a tune up as they are generally needed to be done at 30K and 60K. They will change your plugs, air filter, fuel filter, clean your throttle chamber to remove buildup, and sometimes run a fuel system cleaning procedure. Since the Check Engine light issue is always an emissions related issue, there is no need to panic, and you will not do harm by driving with it on. I have had many a customer drive the car 100k plus miles with the light on. But eventually you will want to get it looked at.

SOURCE: just replaced belt and alternator. Engine squeals very loud when started. What should I check next? belt tension seems good.

Sounds like the new alternator was run without first fully charging the battery (12.3 - 12.8 volts)
This will destroy an alternator every time -- the classic symptom is a squealing belt.
