The timing chain of a 1 year car is ringing, and the quality is too poor. Generally, it seems that it will only be replaced at around 60,000 yuan, and you only ran away 1. 1.00 million yuan. This should be negotiated with 4S point, but if you can't meet the warranty, 4S will replace it for you free of charge. However, it is necessary to explain to 4S what will happen after the replacement, and it will not break down after running for one or two thousand.

Technicians in regular 4S shops will be trained by the chief engineer, so there is no problem in operation, which can be assured. Moreover, the machinery is not so mysterious, and replacing the timing chain has no effect on the life of the engine.
