This car is sick.

Friend, listen to what you said, it is likely that their maintenance staff broke it. Generally, it is enough to replace the antifreeze and expel the air. The car runs for 20 minutes at most. In addition, coaxing the throttle two or three times is enough.

There are many cases like yours, and many car owners are cheated if they don't understand, which is generally caused by the ignorance of the maintenance master. It's no use arguing with them. You'd better go to the auto parts city to buy parts and replace them in the repair shop, which will save about 200-300 yuan.

Decide for yourself!
