but the question to be asked is, who will ensure the enforcement that the standards are kept?
i choose to believe that these "standards" in place are guidelines but are never followed - an aspiration, per se.
i refuse to believe that electronic parts are manufactured to last for at least 15 - 20 years because it shows when car manufacturers are only giving limited 5 years manufacturers' warranty instead of like, say, 10 years.
citing the recent example where almost all facelifted Accords have "one-eye-blind" DRLs, i find myself in contradiction if i were to subscribe to the notion.
i however have no doubts in respect of the safety related electronics.
You are misinformed or do not know how stringent the industry is. The entire supply chain needs to conform, any business who choose not to follow face losing millions in business because the product lifecycle is so long and if you miss the qualification window or fail repeated audits and test, then your business is seriously impacted.
What the car manufacturers choose to give as warranty is not the same as the requirements they give their suppliers. Also you need to remember competition, if say Car manufacturer X can buy from supplier A or supplier B, and both supplier sell at the same price, but one supplier can show reliability of 20 years vs another which can show only 10 years, which you think X will buy from ?? Remember the price are the same, sometimes maybe the the 20 years one can even be cheaper.
If taking the example of a car headlamp... it will have various plastic, metal, alloy and electronics parts from many many suppliers... If you're the car manufacturer you will give warranty assuming the worse case and taking into considerations the least reliable part. Even thought say the control IC can last 20 years, but the LED driver may only last 10-15 years, and you have many of them. One failure out of the say the numerous chips will mean the whole headlamp fail and you get an unhappy customer.
Most of the times the electronics maker have a generic part that can be used for safety and most other parts of the car, take for example a normal IC switch, because you never know how it will be applied, it has to be designed with the most stringent possible use... so that means need to assume it's safety related.
