mr. liu has been troubled by engine fan problems since he bought the car in 2021. according to mr. liu, the engine fault light comes on frequently, and every time he repairs and replaces the engine cooler fan assembly. so far, he has replaced three electronic fans.

the photos provided by mr. liu show that the most recent fault occurred on the evening of august 9, when the car was driving and the engine fault light came on again. since buying the car, mr. liu has lost count of how many times the engine fault light has come on. every time it is repaired, the problem always seems to point to the electronic fan.

last july, mr. liu had his vehicle repaired for the same problem, and the 4s shop promised to completely repair the vehicle by the end of august. but in july this year, the same fault occurred again, and mr. liu had to replace the fan again. he was worried that if the electronic fan did not work, it might cause poor engine heat dissipation.

mr. liu bought his car at a 4s store near his home, and he also replaced the fan three times at this store. but now, the 4s store has been delisted, and mr. liu is worried that he may have to pay for repairs at the new 4s store. mr. liu hopes that the old 4s store can communicate with the new 4s store to share fault records and causes. but the staff of the original 4s store responded that since it has been delisted, their system has been disconnected from the manufacturer and can no longer provide support.

the person in charge of the after-sales department of the new 4s store said that the fault code records of the previous times still pointed to the problem of the electronic fan. he mentioned that if the problem is not solved within the warranty period, the chevrolet brand will continue to be responsible for the warranty. after testing, the 4s store suggested that mr. liu leave the vehicle in the store for a comprehensive inspection to determine the cause of the fault. the person in charge said that the problem may not be caused by the electronic fan, but may also be caused by other sensor false alarms or wiring problems. they hope to conduct a comprehensive inspection to reduce mr. liu's troubles in encountering faults and repairs again. the inspection is expected to take two to three days.
