Why is the cost of car repairs so high?

A survey of the average car repair cost in 2016, conducted by CarMD, a repair data provider called “2017 vehicle health index”, found that the cost of last year and 2015 increased by nearly 3%. The average maintenance cost is $398. This is for minor repairs, not collision damage. The index, released in April 2017, has been repaired 5 million 300 thousand times in its database, so I think it’s a fairly comprehensive and reliable source.

There were five common repairs. The most common is the oxygen sensor fault (8% maintenance). Followed by catalytic converter (6.75%), followed by a faulty ignition coil and spark plug (6.23%). Surprisingly, a loose gas cap is responsible for 4.16% of the “check engine indicator”, and the last is a mass airflow sensor (3.84%) that does not work.

I collect and recycle old cars, so I’m very familiar with these things, and I’ve personally experienced these five cars last year. Because I have a full of old Alfa, Jaguar, Citroen and other garage, the five thing is I most worried about. I usually have to face a piston is buckled, camshaft, bending fried computer, curved frame, body or internal damage, and you get the picture.

Once, I repair a car under the hood of Citroen – Martha Lahti. The hood of aluminum melt, windshield broken, and parts in the engine compartment (rubber and plastic products) (even in twenty years ago by the components made) remind me never, do.

Because I’m not mechanical, so I can’t get close to any power tools, and if I try to fix something myself, then I’ll probably break some of the more expensive and complicated things in the process.


Is the old car more reliable?

Auto repair sometimes people ask me if old cars are more reliable. They certainly have a lot cheaper, buy and repair. Well, you might be surprised to find that the average age of cars on the road in the United States is 11.6 years, and the average age of repair databases is 11.9 years! This is a good proof of the quality of modern car design and manufacture. At the age of fifty or sixty, the car was scrapped at the age of seven or eight, and it hadn’t reached more than 100 million miles. The tires last 10000 miles, and the exhaust system must be replaced every five years. Today, you can get a complete purchase of bank loans in a five year car, 100000 miles, 4% of 4%! The exhaust system goes on almost forever, and the tires last 50 thousand miles. When was the last time you repaired a blowout?

The biggest difference between modern cars and old cars may be airborne computers, coinciding with the appearance of the environmental protection agency in 1970s. The EPA sets standards for emissions, and manufacturers must use electronic controls to manage fuel injection systems that clean up the air (such as spark plugs, combustion and fuel / air mixtures). But that adds to the cost. According to Edmunds.com, a new TOYOTA corolla costs $1700 in 1968 and costs $18500 today. Of course, for a true car collector, it’s a home appliance, not a car!

Now the good news is that airborne computers make it easier to diagnose problems. In 1980s, the automobile engineers association (SAE) established a general system called “on-board diagnostic system”, that is, “OBD 2″”. In 1996, this became a mandatory requirement for manufacturers. Last year, I bought a OBD 2 card reader (less than $100), the diagnosis (lead seal of the spark plug in the valve cover gasket leakage) is very helpful. Using modern cars, you can just get the reader into the connection below the dashboard, and you can get code that can be cross referenced through the code manual and its meaning.

Another consideration is the complexity of modern vehicles. Today’s new car has an average of 30000 parts. There are 50 to 100 computers that control engine management, steering, acceleration,
