Electronics, transmission, engine all stop working

The car runs and drives great until it doesn't. Just driving down the road or waiting in traffic, the car will go from being normal to leaving me sitting. It will suddenly have a small increase in RPMs followed immediately by all the gauges bottoming out, radio goes out, check engine light comes on, check transmission, check charging system, and traction control light all come on. This all happens within a second or two and as soon as it does all that the car will not hardly accelerate or respond to the gas pedal. It will completely die sometimes when it is doing all of this and then it'll start back up sometimes and sometimes it won't start for a few minutes. And over the past month it has gotten worse and more frequent, as well as having a weird transmission issue where it won't let me move the shifter from drive to any other gear. Sometimes it grinds like it's stuck between gears, and keep in mind it is doing all of this stuff within a couple seconds. Sometimes when it is doing all of this it will continue to do it until I shut the car off and let it sit for a few minutes, then other times I can be driving down the road, all these issues pop up really fast within a couple seconds and then it will immediately go back to normal. All the gauges and electronics come back on, car will respond to gas pedal again, it turns back to normal. I've not noticed any kind of pattern as to anything at all that could trigger these symptoms. They are completely at random, day or night hot or cold driving or sitting still. I'm puzzled, any possible feedback or advice would be greatly appreciated.
Do you
have the same problem?

This sounds like a weak connection issue or a voltage issue. Do me a favor. First, check the battery terminals to make sure they are clean and tight.

If they are, I need you to check the alternator voltage output. It's really easy, but you will need a voltmeter or a multimeter. Here is a link that explains how it's done:


I have a feeling the voltage is getting too low and causing issues. This is a theory at this point, but the modules/computers, sensors, and so on are affected by low voltage, and this seems to involve everything, even the radio.

If you are unable to perform the alternator test, stop at a parts store and ask them to check the charging system and load test the battery. Also, if the check engine light stays on when the engine is running, have them scan the computer for codes. Most will do all of this free of charge.

Let me know what you find or if you have questions.

Take care,
