My 2018 Hisun sector crew engine cut off after about 15 minutes run. There is no indicator of what is wrong, no error code just die and won't restart until it cool down. I notice that the fan is not running but the temp indicator is on low temp, no overheat indicator. I checked the radiator fluid, it is cool to touch.
Cooling fans are working, I can hear it running once awhile if I can get the engine warm up enough. Thank you for all the help.

I've been looking at various types of UTVs in the 400-700cc range. It seems that Massimo has a really good price point but I don't know much about their reliability and availability of parts. Been looking specifically at their T-Boss 550. I've heard the parts might be an issue because the network is smaller, but couldn't find much info from owners.
Here are a few specific questions about them
1. In your opinion, are the reliable? Specifically, have you hand any parts break that in your mind shouldn't have?
2. If you had one and got rid of it, what was the reason?
3. If you don't recommend Massimo, what would you recommend (even if it costs a little more)?
4. How easy is it to find a place to service them? How easy is it to get parts if you want to service it yourself?
If you have any other advice, I would appreciate it. I'm also looking at the Hisun Sector 550.

(posted a similar question to the Hisun folks) Looked at a lot of UTVs lately. Couple Questions about Massimo. Some people say they are just cheap with no customer service. Other people seem to have no problems with them.
Any opinions on Massimo durability?
Heard parts might hard to get. Is that true?
What models are the best?
If you had one and didn't like it what do you recommend?

Mine is overheated/burned/melt at connection with its wire connector, parts are ordered to replace both them. This seems to be a common issue, and some of you already replaced it. I right now just connect the wires, so the fan runs all the time whenever the initiation is on, but it's better let fan runs as needed with a working temperature sensor/switch.
Question: Does some coolant come out by removing the switch/sensor from radiator? Or, is the threaded hole all the way inside radiator? If the answer is yes, I want to drain or extract some coolant to make its level below the sensor before replacing it, so I don't make a mess with coolant spilled out
Thank you.

I purchased a new 2023 Landmaster UTV L4 in October of 2023. UTV didn't seem to have as much power of the demo L4 that I drove but figured once it broke in it would be better. After about a week the unit started bogging down backfiring and stopping. Gas fumes really bad, wait a few minutes and it would start up again. Brought it back to the dealer and after keeping it for a few weeks said he couldn't find anything wrong with it. Got it back home and it started acting up again, brought it back to dealer a week later and he said he found couple things that might cause it to do run bad and he was able to replicate the issue but didn't really know what was wrong. Got it back home again after being at dealer for several weeks and the unit started running bad again right away. Brought it back to dealer and he went back and forth with Kohler about possible fixes but just checked somethings and try to swap a few parts but still runs bad. I called Landmaster HQ to speak with someone about a refund and was told that was handled at the dealer level. Dealer called Landmaster and they told him they didn't do refunds or exchanges especially with units that had problems. The dealer is now trying to get a new engine to but I have not heard anything as of yet. I did file complaint with Better Business Bureau and they accepted my claim and reached out to Landmaster. The National Service Manager called me and said the he had been contacted by the BBB about the complaint and he would look into it. I told him that I would just like to have my down payment of $2,000.00 returned and never mind the over $1,000.00 I have paid in notes for a UTV that I cannot even ride on without hoping it gets me around the neighborhood. I have found out that the 2024 Landmaster UTVs will have Vanguard engines due to issues with the Kohler engines. Very disappointed in what is "Proudly Made in the USA" and the way Landmaster has treated this disabled veteran!
