The three-time world champion had finished with results of 14th, 16th and 11th across the three races at Ningbo International Circuit.
The high was starting race two from pole in his Lynk and Co. 03 TCR thanks to the reverse grid, but he soon ran into a major low after failing to convert a near race-long lead into a win.
‘That was a tough weekend,’ the Guernseyman said afterwards.
‘On Saturday I had good pace for race one, but was run wide in a fast corner and lost places.
‘Then on Sunday for race two it was nice to lead a race again. I had that pretty much wrapped up and under control, but sadly it was not to be as I was taken out by another competitor.
‘For the third race I had a really good start and then got a big hit from the rear and that cost me the race as I had suspension damage.’
Priaulx went in hoping for his first win in over 21 races so far this season but again watched his hopes slip.
This was not the case for teammate Yvan Muller, who started and ended the weekend with a win.
‘Sadly for me that first win has still eluded me, but well done to my teammate Yvan Muller, who won two of the three races and is now in a great position in the championship standings with three races to go,’ added Priaulx.
The next race in the championship is in Japan at the iconic Suzuka track.
