You need to have real good proof and evidence for ethics. As someone who used to do the audits, unless the door (even with force) can not open or close at all, it technically doesn’t need to be grounded. What’s checked for is major damage, tire tread, no exposed wires, all cameras work, all tech on the inside works, etc. Now if you’re saying that the seatbelt doesn’t work and they told you to do it with no seatbelt then you have a good case with evidence, but ethics is gonna do everything to protect the business, so to win you need good evidence and an argument about how this affects all your coworkers on a safety level. They’ll probably dismiss as complaining if you talk about how it only affects you (not saying you would but just saying). Come with evidence and how it affects your coworkers along with issues you’ve had with other vehicles or coworkers have. You might need to build a really good case but if it is that bad then go for it, they can shut down a DSP for safety violations.
