Hello. I have a 2003 Nissan Sentra with auto transmission at about 62,000 miles that's been running perfectly well. I do not know what the engine size is. Today, at a red light, my engine suddenly became quiet (could no longer hear normal car sounds). All of my warning lights turned on (brakes, oil, battery, engine service soon). Pressing the gas pedal provided almost no movement. The brake pedals then became hard and I could no longer press down on them. The headlights were still working fine.

I was able to pull over and turned it off. I checked my oil level/appearance and it was fine, brake fluid level/color was good, and power steering level was good, but does look dark. Even while the car was off, I could not press the brakes since they were still hard. After starting up the car, all of those warning lights were no longer on and I could press the brakes and gas again. After shutting it off again, the brakes became hard. I decided to drive around a parking for a bit to make sure it was safe and went home.

I was hoping someone could enlighten me as to what had gone wrong and what I should get checked out/replaced? ANy help is greatly appreciated. Thank you.

?? Confused a bit but all of that would happen with a stalled engine but you said you were able to move it??

If engine RPMs dropped way too low to almost a stall same could happen. Wild guess is a wild vacuum leak like a brake booster or something for now,

I'll go with Tom on this one.

Your engine died, you were on a downward incline and just rolled to the side.....

The brk pedal will get hard after a pump or 2 with the engine off. The running engine is the vacuum supply for the power brks.....No running engine.....No power brks...

Thanks for the replies. Yes, I think the engine stalled. And actually, I think I was on an incline and was able to get off to the side of the road because of it. Apparently, it's possible that I have bad camshaft and crankshaft sensors. There was a recall on Nissan Sentra 2003 models, but I'm gonna have to call a nissan dealership and see if my car qualifies.

Yes there was a recall so get them changed if they are covered. You also might what to get the codes pulled just in case there was something else in the comp system that caused the car to die.

If you haven't had the fuel/air system serviced, it might not be a bad idea to get the injectors, throttle body & intake cleaned. A very dirty throttle body can cause a car to die @ idle.
