  1. Game will not launch after update. Gets to 80 % and will not go any further. Tried reinstalling 2 times and still same result.

  2. Thanks for the throttle fix man! Really helped! I was just making cars on and on without driving them till now lol.

  3. I’ve completed two different orders now & when I go to finish them it says “hood is missing” & neither of the jobs required the hood coming off. Hopefully you guys can fix soon cause I have 10k waiting for me once I can turn those orders in.

    • Same here! Plus there’s no way to even end the job as incomplete. I’ve tried buying a new hood, which is the only other option I could think of because I haven’t yet unlocked the ability to fix body parts as yet… Really hope they fix it soon because the car is now just sitting out front, taking up valuable space…

  4. Just purchased 3 Barn vehicles (can’t recall what they are) and sent them to the Garage. On return to garage I get the “Problem with the following assets: V8 OHV Windsor” error with 2 options (Quit & repatch or Continue & cars/parts removed). Similar issue was had with CMS 2018 (Ford DLC), but no Ford DLC for CMS 21.

  5. I have not got the update version 1.5 and they talk about 1.6 now how can I get it do I need to redownload it or what

  6. Unable to put front plate on Royals Town causing me to be able to finish order.

    The plate is blocked by the bumper but the bumper has to be put on the car first before the white outline of the plate will show up.

    About 6k tied up in car and no way to finish.

    I am playing on PS5

  7. I am doing a story car and front it won’t let me put a licensed plate on it to finish it I tried switching front bumpers still can’t any 1 got any answers

  8. V8 ohv i engine parts missing and also can now only fit 3 cars at my garage when trying get put any more it’s says no space garage can only fit 5 vehicles this is on ps4

  9. Can someone please tell me why I’m not able to get the update for car mechanic simulator 2021 it a lot of parts missing

  10. I can’t finish the story mission 11 i think it is, it’s the royale Town. It says That the hood is missing but i never tok the hood off in the first place. I have tried to take off the hood and put it back on but it won’t work, i tried to relode the game but i still can’t finish the Job.

  11. Yeaahh, this is what I was looking for. I’m frustrated about how to fix this problem, can’t drive or brake. Thank you so much

  12. TLDR: can’t complete jobs.
    So I had an issue with the 80% loading time after the latest update on ps4. I waited 5 minutes and it finally loaded. But now im having a problem where I have 2 cars in the garage. I fixed one completely. Then went to finish the job. And it said hood was missing. It wasn’t. But I figured maybe it was a bug from the update so I bought a new hood. Installed it. And then it said front bumper was missing. Rinse and repeat. Rear bumper missing, again I replaced it. Right headlight missing. You see where this is going. Restarted the game. Reloaded my save. Same issue. I even tried finishing the job incomplete. Says the same things. So I don’t know if this is a bug throughout the game. Or just with the cars I had in the garage that were effected by the update. Just figured I would throw this out there to let people know and see if I’m the only one having these problems. Im gonna do some more testing and I will update when I know more. But let me know if you guys are having the same problems.

  13. I can’t put new wheels on the car only allows me to put the old ones even if all the sizes and dimensions of the old wheels are exactly the same

  14. I’ll load into the game and try to load into my save but it quits the game before it finishes loading into my save it gets to around 80% then crashes
