Gwm terrible service and care.

I wish i can show the video. On 25k gwm still doesn't want to replace the air filter the 2nd most important service part on a diesel engine. My filter is terrible dirty but they don't replace air filters on 25k. All other manufacturers do replace every 10k not gwm. No wonder. And gwm simply don't care. This is a terrible brand and i super strongly advice against buy this. I did support them trying to make there brand better cause there are bad faults on them. Which they don't even know how to sort out. But this is getting to much this bad service from gwm.
