Hey there! I bought my Haval Jolion HEV 3-4 months back. It has been driven 8000 KMs so far. I had a issue a few weeks earlier where the check engine light came on and the an error message for "Aux Water Pump Malfunction" was shown. Heater stopped working too. Drove it to Haval Service Center and they said that the coolant level is too low and simply topped it off. All the error codes and indicators have disappeared since then and I have been driving it around. Now I am facing a weird problem that the coolant level reduces each day beyond the marked limits. I have checked multiple times and there is no sign of any leakage. Haval service center has also confirmed that there is no leakage. I have to frequently top up my car's coolant and it feels wrong. Will someone be kind enough to advise me regarding what's going on and what should I do? I appreciate any helpful remarks and suggestions beforehand.
