The parking brake on this unit is a JOKE. It is a very crude disk brake on the drive shaft. I can imagine that it could NOT release if left engaged for a long period of time. But since it rarely works well I do not think that would be an issue, unless it had recently been adjusted to work. I find that after adjustment it works well for only a few weeks. It is a VERY POOR design. I carry a block of wood in mine to put under a wheel to hold it on a slope! I have discussed with my dealer about this issue, but have received no satisfaction . I have considered installing a brake line cut-off valve. It works by holding the pressure on your brake fluid (like having your your foot on the brake all the time), then when you push on the brake pedal it releases.

The parking brake on the E1 is a very poor design. In the year I have owned it I have had to adjust it four or five times. I have to adjust about every month to six weeks. I think it was designed by an idiot. Which is possible because there are a bunch out there! I may have to put a hydraulic lock on the brake system. That will lock all four wheels.

It looks like one would need to use one of their chargers to have the ability to use their app.

I have not found anything but a pdf file that list the specs. Hisun does not seem to customer friendly. I have managed to get my local dealer to photo copy some mechanical and wiring diagrams. If you don't have a good local dealer you are on your own with Hisun. They are more of an assembler than a manufacturer. They are shipped in from south east Asia in pieces to North Texas, assembled and then shipped to dealers.

Might try checking to see if your wheels are tight. Lit it up in the air at each wheel and see if there is any play in the wheel. If so take out the cotter pin and tighten the nut. Simple.

I have never liked the cord in the glove box to charge the E1. It takes up to much room and in the winter the cord is very stiff. So I decided to install a charge port like the EV's have. I purchased a weatherproof socket to install in the side of the E1. Wired the charge cable to the socket and installed it. So much easier now to plug the charge cord into the socket, and I have more room in the glove box. On another note: Since I have owned the E1 I have noticed a rattle in the right front area but I never could locate it until last week when I had the E1 up in the air on a lift. When I grabbed the right front wheel it a play in it. So I removed the wheel and torqued the nut on the drive shaft and the play is gone. I am thinking when it was assembled the nut was just hand tightened and the cotter pin installed. I also found that the left front nut was not tight either. Backs were OK.

I have had my E1 since late last summer and I have always noticed that the parking brake was weak or non existent. About a month or so after I purchased it I mentioned to the dealer that the parking brake did not function well. What I was expecting from the dealer, ' well bring it in and we will correct the issue.' What I got was the typical dealer response, "it may just need to be adjusted." No shit! Well I finally decided to adjust it. A very simple process need only two 10mm wrenches. Open the bed, remove the pin holding the bed to the strut and move the bad out of the way. Right in front of the electric motor is a brake disk. That is the parking brake. It has a small set of brake pads that are actuated by a lever attached to parking brake cable. There are two 10 mm nuts on the shaft to moves the pads. Release the inner nut and hold it in place while screwing in the outer nut - that is really a bolt. After screwing it in about one turn, tighten the other nut. Check the parking brake. If it is holding when activated, then you are good, but if not, then you may have to turn the bolt another turn. Do not turn to far or you will lock it up.

Mine and some others that bought one from the same dealer came with a 2 inch adapter that fits OVER the Hisun receiver. I think Hisun left that off your unit. Dealer should provide you that adapter.

I hope you get it sorted out. We call our E1 the Mule, for our other side by side was a Kawasaki Mule! Our two wheeler with a handle that curves out, we call Dolly Parton! A funny: You know what Moses used to part the Red Sea? ..... A sea saw!

Thank goodness we do not have really cold temps here. If one battery is defective it affect your power output. In an emergency there is something you can try. Remove the bad battery. With the power off. connect the two battery cables from the removed battery. If the other batteries are good and charged, you should have enough power to move the vehicle. I have never tried this but technically I think it would work.

In the last year he has had three batteries replaced.

The local Hisun dealer has sold only four E1's in this area. Like me, they use them on their farm/ranch. Chickens and cattle are big in this area of Arkansas. Part of the reason more are not sold here is Hisun is not pushing them in order to sell their gas models. Those who want them have to wait six to 10 weeks to get one. The Hisun distributor in the USA is in north Texas and unlike most Texans they are not to customer friendly! I also have found the inability to purchase certain vehicles in the automotive world. Eighteen months ago I wanted to purchase a plug-in hybrid from Hyundai. I discovered they only sell on the east and west coast of the US. Dealers can not even get them! So I ended up buying a Hyundai Ioniq hybrid. I have really enjoyed it, especially the mid 50's mpg. But if I could have bought the plug-in version I could have gone about 30+ miles on electricity, and most of my round trips from home are less than 30 miles.

There are a few SxS's that use newer technology, ie. lithium batteries, but they are really pricey. The gel batteries in the E1, even though very heavy, work well and are not as temperamental as the lithium. The heavy batteries also give the E1 the ability to pull a heavy load without loosing traction. For example, I got my Dixie Chopper lawn mower stuck in deep mud a while back. I was able to pull it out with the E1.
