Serious quality problems at Great Wall Motors are being exposed frequently to the public, focused on engine failure, air condition compressor failure with abnormal sound, rusty and blistery car doors. Unsatisfactory after-service also angered consumers. In addition, the company's research and development was denounced due to the lack of power in its new 1.5T engine.

Chen Zhen, a well-known car tester, commented that the Hover H6 1.5T was the worst car he had ever driven, Xi'an Evening News reported on Wednesday.

According to some complaints on an auto quality website (12365auto.com), many car owners of the Great Wall Hover, C50 and others faced the failure of air conditioning compressor with abnormal sounds. But consumer services explained that it was normal, with no remedies.

SUVs and pick-up trucks are Great Wall's best products, but quality problems on them are also common.

Many complaints about rusty and blistery car doors can also be found online. Moreover, it is not rare to see multiple problems in one car.

In addition, SUVs, as Great Wall Motor's key products, emerged from serious problems in research and development. Hover H6 is the top-selling star for Great Wall, but it has become the eye of the storm, fueled by the lack of power in its new 1.5T engine.

The Hover H6 1.5T has been slammed by the media and consumers alike.
