One problem related to horn assembly has been reported for the 2018 Tesla Model 3. The most recently reported issues are listed below.
About 6 weeeks ago the horn on my Tesla Model 3 stopped working. I have had one very close call where I almost got in a wreck because the other driver was making a u turn in front of me who did not see me coming. I could not get their attention because my horn did not work. I had to go into the lane of on coming traffic to avoid a serious wreck. I have made multiple efforts to get Tesla to get this repaired. They have failed every single time to take care of this or even schedule an appointment. Communication has been very little and now they are not responding at all. I have emailed them and texted them. Even tried to get them to help thru their twitter account. Please help !!.
