Vehicle touch screen will shut off while driving and take 5 minutes to reboot. I have taken it to Tesla multiple times since November and they said it’s a firmware issue and nothing is being done to resolve.

The is WATER in my right front FOG lamp and I don't know how it got in there, but Tesla says they can't get water out of it and can't reseal it, but is willing to let me pay $504 to replace a light... this is yet another Billionaire abusive practice by Elon Musk to generate cash flow and revenue for his failing company. Telsa also asked for $15,000 for a new battery, which the "software" said it started reducing the range JUST after the 120,000 mile battery warranty was up. Just like Apple does with reducing iPhone battery performance for so called "safety" reasons to make people pony up to the latest model. Which Tesla has been emailing me and texting me to try to get me to buy a new Tesla LOL. This is clearly an abusive "sales tactic". If they actually care about helping customers, they would figure out how to fix each issue. Clear out the water and seal the headlight. Figure out which battery cells need replacing and replace them. Simple and cheap solutions. Not "customer pay astronomical prices" for every damn issue Tesla forces upon people. Including "customer pay tows" after "Tesla's software" decides to randomly shut the car down in the middle of the road, rather than Tesla taking responsibility for their software malfunctioning preventing the driver from reaching their destination. These are clearly misguided attempts by an AWOL CEO [XXX] about his $55B pay package, trying to claw back money from customers to reward himself to pay for Twitter/X. Make[XXX] Musk and Tesla do the right thing by customers and REPAIR these issues, rather than [XXX] poor customers' cashflow.

A charging warning error msg appeared that there maybe something wrong with the cable leading to charging the battery and may lead to a fail charging and this the 2nd time. The first time I had a failed charging with no warning that it was failing amd that lead to the entire battery wouldn’t charge leaving me stranded and the car had to be towed to a Tesla service center., this time 02/08/2024 it’s sending me a notification that there is something wrong internally and I need to see service asap so this time it did send me a msg warning me there’s something wrong

My bluetooth has not been connecting in my car. To preface this, my car was in twice this year alone, with a near $3000 bill, to replace the MCU, on a car with only 26k miles. Now this bluetooth connection issue is still a problem. After opening a service ticket with Tesla, I am told for an additional $180, I would need to replace my seat sensor. This means my seat (while I am driving) does not recognize that someone is on it and driving. My concern is the manufacturer remedy does not replace failed parts with improved design and that this has the potential to cause other safety issues if occupant detection compromised by faulty sensors. What if I am in an accident and the airbags don't deploy?

We intermittantly received alerts on the screen showing "Front safety restraint system fault (service is required)." After many hours of research, we found that other owners also have the same issue and they found that a wire from a electrical connector that connected to the seatbelt pretentension was broken from the seat being moved up and down.

Touchscreen went entirely blank. A few days prior to this, radio cut on and out. Rebooting procedures did not work. Tesla repaired, stating it was the cars computer. I asked for the old computer board but was told it was proprietary. The symptoms are very similar to those of the older memory issues.

There is an ongoing issue with Tesla's seat sensors that give an error screen while driving. Tesla seems to be systematically charging a standard $1.5K repair to replace a $100 sensor harness, but they're charging so much because they claim an airbag replacement is required (for an extra $1.2K) as part of the new sensor/wire harness installation. From a quick google search, it seems this is a pretty widespread issue that MANY Model 3/Y owners are encountering as their car ages-- with many noting that they were able to self-service the issue with buying the required harness and replacing it themselves. I wanted to bring awareness that to this issue and Tesla's poor and systematic way of overcharging customers to fix a widespread defect in their car seat design.

My car went out of warranty for seat related issues in December of this past year 2023. I don't even have 26K miles on my car therefore not a heavy driver. This week I experienced an error RCM_a021, front left safety restraint system fault, which I've researched has affected many others and appears to clearly be a safety flaw. The service team mentioned this isn't covered. My airbag light doesn't go off and is constantly on, my seats no longer save the seat setting (which occurred a couple of months ago but I didn't think about it).This is a safety hazard should I get into an accident. There were no previous warning issues prior to this warning error which occurred this week. According to Tesla, if the airbag light remains lit, schedule a service appointment immediately and do not drive. The service team mentioned the seat harness is faulty remotely and according to what they can see. I have not had them look visually yet though. They do not cover the repair for this as it's out of warranty. There's even a bulletin posted on this issue/repair by NHTSA therefore is known problem. [XXX] I'm unable to upload any files.

Got into car after update, screen blacked out, could not to hard reboots. App could no longer see car. Tech support couldn't remote into vehicle or get in touch with it. Had to have it towed to service center. It's been sitting there for 6 days with no diagnosis just an estimate for $530 to troubleshoot the car. This update caused my car to completely be unresponsive and undrivable. I also had a carseat in the car.

Low coolant alert while in the hidden service mode only. Happens to all my 3 cars. Went to service to fill up the coolant and the warning didn’t go off. They said is a sensor gone bad and it’s $1000 to repair. What are the chances that all my 3 cars have that issue and all not actually having low coolant

The only cabin heating and defrosting mechanism in early model 3s, a PTC heater, is prone to failure leaving the vehicle without the ability to maintain clear vision through the front and side windows. This occurred on my model 3 in November of 2023 and Tesla was unable to source parts for several weeks, with a cost of $900. This failure is extremely common among model 3 in cold weather environments and is well documented online.

The contact owns a 2018 Tesla Model 3. The contact stated while driving at approximately 35 MPH, the Front Passenger Safety Restraint System (FPSRS) fault warning illuminated. The contact continued driving and later contacted the manufacturer. The contact was advised by the manufacturer that he had the option to repair the Safety Restraint System by a mobile technician or the vehicle could be driven to a dealer. The vehicle had not been repaired. The contact stated that the Restraint System fault warning failure was intermittent at first but had become a recurring failure. The contact researched online and related the failure to the FPSRS wiring located under the seats, which was being damaged by the seat auto adjustment feature. The seat adjustment feature moved both seats to an upright and back position to allow ease of entry of the driver and passenger. The manufacturer had been informed of the failure. The failure mileage was approximately 58,900.

I received a warning message that displayed, “Front Left Safety Restraint System Fault.” This is an engineering problem as the cables associated easily detach under the driver’s seat. Tesla has been long aware of this problem. They came out to my home and replaced the wire connection by installing sturdier connectors. I was subsequently was charged $329.40.

The front passenger seat driver occupancy system started sporadically malfunctioning and showing the "air bags disabled" warning even while the seat was occupied. This would put the passenger at risk in the event of a crash. The manufacturer's technician arrived to inspect the vehicle and upon hearing the description of the problem said it was likely that a cable in the seat's wire harness probably wore out from friction and that "it was a common issue in these vehicles". Upon examining the wire harness the technician confirmed that this was the issue, and the harness had to be replaced.

I have had a safety restraint fault on the vehicle once before and Tesla came and replaced something. It never came back. Until I'm a couple thousand miles over the warranty and I "randomly" get another safety restraint fault. I filed the service report for them to tell me it's the seatbelt. I replaced the seatbelt and the error continues. This is a safety issue that needs to be addressed as thousands of people are having the same "fault" codes. This is a known problem teslas have and they are doing nothing to address it. I'm in shock this is allowed to happen

Re NHTSA recall 21V00D The rear view back up camera of my Tesla 2018 Model 3 went black on August 21 starting at approx 3pm and remained black for the rest of the day through August 22. I'm planning to check today, August 24 to see if the problem still persists. Lack of the backup camera makes it very difficult to park and to see people in the car's blind spots. I've informed the dealer of the problem but I've decided to have an independent third party repair service take a look to see if the problem could possibly pertain to recall.

Tesla recalled wiring components for the Rearview camera (for parking / driving in reverse) as it suffered from severe latency. They claim to have fixed the recall but nothing changed. They don't respond to complaints that it doesn't work. This work was "completed" under the Trunk harness retrofit on the statement provided . The trunk harness affected the wires to the camera causing the latency, per recal info/Tesla rep.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Tesla Model 3 Bev verdict →
