2018 TESLA MODEL 3 Complaints

This is a follow up to issue 11584898. Tesla Service states that due to the seat belt fault, the vehicle is not safe to drive until repair is complete. Tesla is also not providing a loaner vehicle until the vehicle is repaired. This puts many Model 3 and Model Y Drivers at risk due to limited Tesla and 3rd party service centers, limited service center schedule availability, and high cost of repair.

What component or system failed or malfunctioned, and is it available for inspection upon request? Front left safety restraint system fault, must replace first row seat harness assembly for seat belt. It is available for inspection. How was your safety or the safety of others put at risk? Potential Seat Belt Malfunction, Tesla states "Service Required"   Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, common issue all over Tesla forums covering both Model 3 and Model Y. The problem/warning is reproducible on personal vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Tesla diagnostics showed service is required to replace front row seat belt assembly due to fault. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, warning on display "Front left safety restraint system fault/Service is required" first appeared on personal vehicle 1 year ago intermittently, but online forums show this issue on similar vehicles dating back to 2019

Following an over-the-air software update, all audio in the vehicle stops working. This includes entertainment services, but more importantly turn signal indicator "clicks", forward collision warnings, parking assist chimes, shift confirmation and warning chimes, and various ADAS notification sounds. In some instances, the problem corrected itself within 24 hours. In another instance, it persisted for nearly a week before I discovered that unplugging the USB cable for the dashcam fixed the problem. The dashcam hard drive has been installed for over 4 years, per the instructions in the user manual, without problems until early 2024. There were no error notifications or anything else to indicate that there was a problem with the car's safety systems, or what the cause of the problem was, except for the lack of audio. I chatted with Tesla service about the issue. After discovering and sharing that disconnecting the USB drive fixed the issue, they were persistent in wanting to cancel my appointment without gathering any additional information. Here is the transcript of our interaction: Me: Unplugging my dascham hard drive from the USB port fixed it. Weird. Tesla: Oh interesting. Good to know! Do we have permission to cancel this appointment? Me: Since it keeps happening I'd like to keep it open. I turned on remote debugging in case that helps you to report the bug or something. Tesla: We have nothing else to diagnose if your vehicle is operating as expected. Me: Ok. If it keeps happening I will still want to bring it in, so let's keep the appointment. And I wouldn't say it's operating as expected. Having to disconnect USB cable to get the turn signal to work properly isn't what I would expect. Tesla: I would hate for you to bring in your car, only for us to tell you that it is because of your third party accessory, and we charge you for the diagnostic time. Me: I appreciate your concern.

Left and right upper control arms failed, as did both front lower lateral links. Same issues as the vehicles recalled as part of 2 different recalls by Tesla: [XXX] Car requires over $2,000 of out of warranty repairs despite this clearly being a manufacturer defect and car should have been included as part of the previous recall(s).

The contact owns a 2018 Tesla Model 3. The contact stated while driving at an undisclosed speed, a message displayed reading "Left from passenger safety restraint system fault".

Tesla Model 3 autopilot engaged. The car steered itself off the road and into a tree as it was accelerating on a residential street from 8 mph to approx. 30 mph.

The most recent software update v11.1(2024.3.10 9d92fb944d7f) was downloaded automatically and I installed it. The next time I drove, the car made uncommanded and unwanted lane changes, apparently because I could "go faster" if I passed the traffic in front of me. I did not want to go faster due to congestion and aggressive drivers where I live. I then discovered that "Full Self Driving" had been activated after the download and without my knowledge or authorization. I believe that this was an unsafe condition and wish to report it. I immediately turned "FSD" off.

I have a 2018 Tesla Mode 3. It is one of the early Model 3 on roads. I have had around 10 issues in the car over the past 6 years of ownership; and most of them were fixed during warranty. My car has no accidents, no water damages (only hand washed), single driver driven and well maintained. Around a month ago, I got an alert in the car “Condition Detected with Controller”. Tesla Service did remote check and stated that VCFRONT (Front Body Controller) needs to be replaced for $900. I took the car for this fix and then heard that VCFRONT Controller is fine, but I need a replacement of Harness and Steering Rack for $4200, as they see corrosion. I told them that I have no issues with driving or anything else, as $4200 is around 25% of the value of the car. I was advised, pay for this amount or take the car. I got my car without fix. My concern include (i) if this is corrosion issue (Model S 2018 and before also had the same issue and there was a recall), then is it their part quality or design quality issue or is it a normal car’s aging issue? (ii) I see malpractice of charging exorbitant $4200 for something I do not see any issues in driving or anything else, and importantly, not sure how are my future repairs going to look like $$ wise. I have request for NHSTA – can I show my car to any entity like yours (and not Tesla Service) to get an advise whether (a) this is a corrosion issue by manufacturer or normal car’s aging issue (b) is it critical car to replace one or both parts (c) is this a malpractice to burden owners with this high cost of maintenance, once it is out of warranty? (Please note that Tesla never offered extended warranty for my car)
