Experience 1. Routine maintenance, exaggerating problems, and letting car owners do more maintenance projects.

Many novices are inexperienced in first-time maintenance. 4S shops take advantage of this, saying some technical terms in maintenance, exaggerating vehicle problems and guiding car owners to carry out more maintenance projects.

For example, when the engine was first cleaned, there was a running-in period in the early years, but now the production technology of new cars, whether joint venture cars or domestic cars, is very mature, and there is no so-called running-in period. The so-called new car engine has problems such as debris and oil impurities, which are basically the rhetoric that 4S shops let car owners clean their engines.

Experience two, maintenance, "short weight, shoddy.

At present, household models are generally used in synthetic engine oil, and some technicians in 4S shops and external repair shops can do some things. The original owner asked to replace all synthetic engine oil, and the technicians directly replaced all synthetic engine oil with mineral engine oil. If there is no monitoring or the owner is not at the scene, it is believed that it is difficult for the owner to know whether he has changed the fully synthetic or mineral engine oil.

Similarly, the oil filter is usually replaced with the oil. In order to save money and convenience, some repair shops directly remove it, blow it clean and reinstall it. Every day, it is euphemistically called "changed", and the money is still collected according to the new filter. Some riders even said that some repair shops did not replace the oil filter at all.

Experience 3: Exaggerate the car failure, "just change it, not repair it"

Once, my colleague's car started at full speed. If he didn't fill the gas door, it would soon stall. After he drove to the 4S shop for inspection, he said that the intake manifold was broken and the total speed motor was faulty, so it needed to be replaced. The total maintenance cost needs to be around 650 yuan. Colleagues think it's a little high. Anyway, he already knows what the problem is, and it will be much cheaper to go directly to the repair shop outside for repair.

So I asked my friend to introduce a repair shop. The boss looked at it briefly and told him directly that it was a small problem. Just wipe the throttle clean. It was done in more than ten minutes, and all the money was confiscated. I have to say that this wave of operation of 4S shop is to "pit" Xiaobai.

Experience 4. Recommended maintenance vouchers and maintenance packages

When buying a new car, 4S shop sales recommended me a maintenance package, such as one-time payment 1 000 yuan or more, free maintenance of the vehicle for life, individual maintenance times or coupons, etc., but when we understand it carefully, we will find that there are many conditions. For example, only for routine maintenance projects, that is, oil change, machine filtration, routine inspection, system upgrade, car washing and other projects, others need to be paid at their own expense, although giving away many projects is actually of little use and not cost-effective.
