The purpose of my interest is doing research into possible auto that I will purchase in the future. Because some vehicles are more expensive to repair than others. I want to find out what kind of bill I will get hit and when. So I can anticipate my auto repair and maintenance costs in advance.

So, now today there are so many sensors. What if one breaks down how will it affect the car? will it be "bricked" will it be drive-able?

There's variables relating to the quality of the repair and diagnostic service I realize now. That's a valid point to consider.

Overall my purpose was to figure buying an car maybe 3k-6k price but older with low miles. 2000-2010? Or buying newer 2015ish for 15k which would be more expensive in the long run? How long do the cars run without getting problems.

I have a car 1997, I do fixes on it more often now but it's in the range of 400-800 each fix.

On my next purchase. I want to anticipate the price range of each fix I will have. It depends on how well you want to maintain your auto I realize that and that also varies person to person. Some people will just not fix a broken part if it still is running. Others will run to a shop and pay whatever to get it fixed.

In the whole picture it's hard to exactly know I agree. However, it should do able to find out a range of price that I can expect to pay for a breakdown. Water pumps break, tires go bad, rotors wear down and you don't replace on time. Common problems that happen. Will I get hit 1000-1500 dollars? 1500-2000 dollars? 3000? Newer cars can run without maintenance other than oil change and simple things to maintain, tires, wipers, fluids.

One way, compare part costs on each auto is one way to look at it. Comparing labor needed to fix something is another way.

I was looking for common fixes that happen on a car and of course it varies for each auto. That is my question. A list of auto repair issues. Then I can look up the costs on each. I can look online a breakdown and get a estimate. Problem I do not know on newer cars what kind of breakdowns are common and when they occur.

Suppose an 2015 Mazda cx-5 for example is fully loaded with sensors. What if one broke. What is the part to fix it. Is it common for breakage to happen? How much if something went bad and I have to fix it? Can I live without the sensor? How do I do research? I need to know what to repair. The name of the repair issue.

Give you an better idea of what I am trying to do?
