After 10 hours of use, my machine had developed a low speed brake squeal. I removed the brake assembly and discovered that everything was put together dry. Not even lubrication on the caliper pins. After lubricating and reassembly, the squeal has disappeared. I will do the other three wheels today. Also, all grease fittings were under-greased (if at all) based on the amount of grease filled before they purged. This includes the drivelines. Next- I found many screws which were loose and/or stripped. I was able to tighten or fix them with my tap and die set. The lower a-arms on the front do not have grease zerks. I will remove the arms and install some. I guess I’m not surprised or even disappointed. These are just things that should be looked at on any machine. One thing I am pissed about though, is this “weld from hell” on the front . Totally unacceptable. For sure there will be water entry and eventual internal rust. (see photo) I will fix it. I did an oil and filter change which some of you will say was not necessary. But break-in time is when you are most likely to have contamination from production and initial wear-in. BTW there was some metal in the filter. Cheap insurance to change often. Engine access is very difficult on this machine compared to other models. You have to remove lots of stuff to get to it. But I still like the machine very much, and I’m having a ball with it. Future plans include lights, cab enclosure and heater. Winters are long in Northern Michigan. PB

Hello everyone, I'm new to the forum, and looking for some help. I have a 2021 Vector 500 that I purchased in July of this year brand new. I was very careful with the break in period, following Hisuns recommendations to a tee. The machine now has 37 hours and 589 miles on it. It has never towed anything, and only been off roading once, but not hard, just some hill climbing and a few mudholes. I mainly use it for cruising the back roads, and going hunting. The other day I was running up to the gas station to fill it up with gas and I was in low range driving down my private road. When I got to the main gravel road I stopped, shifted into hi range and went to take off. When I hit the accelerator pedal, something popped, and it something in the drivetrain is skipping. Or so it feels. I limped it back home, about 900' and put it in the barn. It does this in low and hi ranges, but not in reverse. 4wd seems to help a little, but I am not confident that it's not coincidence. At 10 hours I changed the oil with Lucas 10w40 SxS/UTV synthetic blend JASO MA2 with a factory filter. There was some large shavings/pieces in the oil when I changed it, which I was told is normal due to the wet clutch break in and assembly. It didn't seem right to me, but I was told not to worry about it. I did add the dipstick extension tube, and am running 3 qts of oil. I've tried calling 2 different shops near me that I got off of the Vector website as service centers. One will not answer the phone or call me back, one said they don't work on Hisun anymore, so I think I'm just gonna tackle it myself. Does anyone have any ideas on where to start? Thanks in advance!

Question, is the accessory switch prewired and if so where will I find the ends so that I can use for light bar and pods?

I have a new to me 2019 vector 500. It has 250 miles and is in very nice condition. This thing will not go over 22mph. Low range is good to 20mph but high won't go over 22mph. Reverse has more power and is faster than both forward gears. Both seat belts are plugged in. What is the problem here? It has zero power in high gear.
