I am working on a 2018 hisun hs 500 4x4 with 9.5 miles.it starts good if you push on the gas pedal a little bit it runs pretty good.if you push it on down it cuts out.

That series of engine isn't designed for performance, but they are very reliable as long as they aren't over heated. Their biggest weakness is the lower intake manifold gaskets are known to deteriorate and leak.

Sounds like it's time to replace fuel filter, or possibly a bad fuel pump. I'm uncertain why the gas pedal would be hard to push as it most likely isn't a cabled type on that new of a vehicle, but you can check by looking at the top of the pedal itself to see if there is a cable and if it's possibly frayed.

yeah, it should start without pushing the gas pedal. Sounds then, like too little gas, or too much air. I would start with a fuel pressure test to see if pressure is up to specs. Also check for any vacuum lines disconnected or bad. Might want to see if engine has any trouble codes. Some parts places (autozone) will check for codes for free. When was last time you changed your fuel filter? Might need replacing. Good luck.

DID YOU REPLACE AIR FILTER AT 25000 MILES FUEL SYSTEM NEED SERVICED AT 25000 MILES ALSO PROBLEM COULD BE STOPPED UP FUEL FILTER OR FAULTY ACCELERATOR PEDAL POSITION SENSOR OR WATER IN GAS CAUSE ENGINE RUN ROUGH. .HAVE VECHICLE SCANNED FIRST. BEFORE BUYING NEW PARTS. HAVE FUEL SYSTEM SERVICE CLEAN FUEL INJECTORS ALSO.

It sounds like the gas control lever under the hood may be sticking a little and not retracting fully to idle.Open your hood and have someone start your car.When they give it some gas you should see the actuator move which has a cable attached,probably located at the end of the fuel injectors on the driver side.It should be pretty noticeable as about the only moving mechanism when the gas pedal is pushed.Usually pushing the gas pedal makes the lever move toward the driver.Once you have found it,push down on it in the opposite direction as giving gas to see if the revs decrease back closer to idle.If it does,WD-40 on the hinge where it pivots may help.Spray it,rev it a couple times and check.Even if it works on the first try,do it a couple more times.If this does not work,please reply back and I will get an auto link to see what you posted. Good luck! Greg

sounds like your brakes are taking too long to disengage. Your problem may not be your gas pedal. If your brakes are sticking it could be holding your acceleration back just a bit until the car gets moving again.

sounds like the clutch needs to be replaced

probably needs a tune up , Plugs and wires

Take the care to the dealer, This car is easily still under warranty and can be diagnosed and repaired for free.

Had the same problem. Just changed the fuel pump today and now working great. Good Luck!!!!!
