Nah, just like with the video games now they shortchange on the software writing and use the excuse, 'if any problems show up we will fix them on the fly'. Car companies can reprogram the computer to affect every sensor on it in different ways now. All cars get things compensated for with software updates left and right now.
I for one avoid them like the plague...........like the old computer adage says, if it is acting right then DON'T go trying to improve it. It was either Toyota or Nissan just a few years baxk that was sending updates to cars just newly out and one of the computer updates turned the cars into bricks, they wouldn't start anfd acted like no key was present at all. That one got into the news. Bad software to correct the bad software.
My son, avid gamer, says now if you buy a new video game before you can even play it you must download up to an hour of new updates since things have changed since the games were 'finished'. Finished my butt.
Nissan saying your CVT trans needs updating is a notable one, they commonly tell you you need one to get the cash when trans is acting up and then the update often makes trans worse to where you have to change it. BEWARE. The update is a reasonable one that bumps the line pressure up slightly with age of car and can work fine but if the usual CVT wonky wear out has shown up it will push the car off a cliff.
The MAF deal............the sensor besides working numbers also has parameter limits that if it gets into signal the computer that the MAF is bad or has something wrong with it. The car may well run fine. They typically want to change the sensor then do an update to widen the band so that the limits are no longer hit, and you don't know, what if the sensor has nothing wrong and they simply gave you another of the same type and the only REAL difference was the software update??? See how that works? It's all about getting as much money as they can.
Why your car has no way to check how much transmission fluid is in it? To see what we will put up with.
Just wait until they bolt the hoods shut.
