My experience is not good

I bought ertiga in 2014,2016,2018 first two was vdi and last was zdi+ in all ertiga there was gear problem after 25000km in 2016 model it was in gerranty period so company change it but I sell all three car because of gear shifting problem I repair more than three times and every time it cost 12000/-rs and more but problem come just next 10000km so I don't prefer to buy be it and it is very light in weight
