Ha, wasn't a problem with studded snow tires and limited slip differentials, and none of all this electronic crap.

Is now.

Most vehicles built prior to OBD II that became law in 1996 had self diagnosis built in. Besides requiring a scanner, created yet another problem by storing code in erasable memory that is yet another brand new problem that never existed before. That code can be erased!

Instead of advertising how great these new vehicles are, should be saying, if you want problems, we have problems.

If you want to hear it straight from an old broken down engineer. The only difference in a military solid state device and a consumer grade device, is that military grade devices are tested to military specifications. Such a thing called yield rates in manufacturing. Those that do not pass the military specifications are so-called consumer grade.

Depending on the device, may only cost a a fraction of a cent more, but were never allowed to purchase military grade, must be operational from -40*C to 125*C, consumer grade is 0*C to 70*C, quite a difference. And the automobile is such exposed to a military environment. For the consumer, you may be lucky or unlucky, deals primarily with leakage currents.

Also have no idea where they are saving money using what is called flashram to store this very important code. Just a 0.75 V transient on the wrong pin can either erase this code or corrupt it. PROM's were the only choice until 1996 with the advent of the internet. Some idiot decided would be cheaper to update the code over the internet than to provide a new PROM chip. But the consumer is paying around 85 bucks per hour for some exhaust only changing mechanic to download this code and to reflash your RAM. As oppose to sending out an 89 cent chip with the code permanently burnt in that will never change.

Worse case scenario is elevated temperatures where the leakage current doubles every 10*C that can also corrupt the code, lose one bit and the computer will crash. One key reason why I selected a white colored car with a light tan interior.

Don't blame engineers for this, any engineer worth his salt knows this, but can't tell you the number of times, was told to do it or will find somebody else that will. If the American public would know this, would leave these vehicles in the showroom. I also started paying 150 bucks per year for towing insurance.

Yet another hardship was dealing with the EPA, have yet to meet an EPA engineer that could handle the industrial world where you also have to show a profit to keep your job. But they have all the power!

And you wonder why you have problems.
