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.

Re the federal safety agency 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.

I was exiting the highway onto a Blvd and I slowed down. The car all of a sudden accelerated by itself, went over the exit curb and hit the central median of the blvd. Fortunately, no vehicles on the blvd wer crossing when this happened. I was fortunately not physically hurt in the incident but it could have been afr worse if I had a vehicle in my front or on the lvd when the incident happened.

Safety restraint system fault RCM_a094

Filed Jul 28, 2023 · Electrical · AZ

The center display that houses all of the cars instrumentation including gauges randomly goes out while driving. It will go out for 10 to 15 minutes until it recovers. This leaves me with no gauges at all including loss of backup camera, turn signals, speed and various other functions. I purchased the car two weeks ago and this has happened 5 times already.

Received an error "Front left safety restraint system fault. Service is required." error on my vehicle yesterday (7/11/2023) which disappears when lifting seat to highest position. As soon as seat is lowered more than 1/2" the error reappears and airbag light is illuminating notifying that the airbag is not enabled. This error is clearly an issue with the safety restraint system on the vehicle but Tesla will not honor fixing this under their Supplemental Restraint System Limited Warranty. The vehicle is within coverage period (<5 years and <60,000 miles). I am being told this SRS Limited warranty covers air bags, seat belt, seat belt buckles, sensors, and modules only. I have not taken the vehicle in for service as the quote I received is too expensive ($601). Please see photos for my conversation with Tesla service as well.

Tesla Vehicle safety concern. Safety May 1, 2023 on Rt 95 south from Washington DC to Richmond VA (near Richmond VA) at about 10:45 pm. (Please note the clock time on the vehicle is incorrect—it is about 5 minutes slower and sets to a time I hr. earlier than the current eastern time). Vehicle: 2018 Model 3 VIN [XXX] The computer system failed in the middle of highway. The computer screen where all system functionality is monitored went bank except for a Tesla icon. Losing control of vehicle including turn signals in the middle of the highway was dangerous and a safety concern. For fear of being stranded on the road I carefully drove the vehicle to home in Yorktown Va. It was scary! Much of the settings on computer and navigation info was lost. This is a vehicle defect I need to report. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

On April 21st 2023, by pure chance I happened to notice that, after plugging in my Model 3 to recharge at a local charger, the charging rate was lower than normal: instead of its full 32A charge, the rate was only 16A. I kept getting a notification of an issue with charging, Error: PCS_a019 "Charging slowed - Poor Grid power quality possible, unplug and retry / try different charging location" I've attempted several charging stations and all the same outcome. I've done research on this issue online and others are having the same issue. Tesla did cover a few from what I read as "battery warranty" that I've reach but most are denied as it wouldn't be part of the "battery warranty". I've reached out to Tesla and was informed my warranty was expired almost 28 days on March 23rd 2023 as it was April 21st when I made the service appointment. The cost to repair was $1,987.58 and NOT covered by the battery warranty. I've asked if Tesla would waive the fee as my car was just out of warranty and has a mileage of 30,193. It was declined as she "informed" management at the Burbank, CA repair location. I'm very sadden by this issue as Tesla advertises the electric car is "low maintenance" compared to the average gas vehicle, this is false advertisement. Other manufacture do cover this part under their battery warranty. The vehicle isn't operable if not repair to charge at a normal faster speed. I'm now considering to sell my vehicle once repaired and give people my honest opinion about my experience with Tesla. I hope there's a recall for this issue so other don't have to go through this issue.

The Tesla was parked and locked unoccupied with all security features enabled. When I returned to the car the front driver's side was completely crumpled with the bodywork torn , like it was reveresed in to. I was gone about 30 minutes. The car gave no notification on the app, the car alarm didn't activate and the sentry mode did not record the incident. All the things they say the car will do. I called Tesla and was told it works 99% of the time ,(but clearly when you need safety and security it doesn't) they stated that if the car gets hit a certain way it can cause the system to shut down /reboot ,so that none of these systems work... Seems wrong that this can be allowed to be the case that not only all the systems fail, that when they do fail there's no backup or way for the car to know something is wrong. That if there is a unexpected forced reboot it doesn't tell you or acknowledge something is wrong in any way . They seem to think that this is ok . I have reported to them and they really didn't seem to care , just said the statement above about it working 99% of the time..However all the things they say the car can do ,and several reasons you think you are buying the car for with it's increased safety and security, apparently don't work at all. Now I have a 4 figure out of pocket to get the car repaired because I have no way to find the person who hit my car because the none of the cars security or safety warnings worked.

My Tesla Model 3 without any warning stopped working suddenly. I could not put the car in drive and there were error messages about climate control and electrical system. I had to get the car towed to the service center as it was blocking my other car in the driveway. The service center in Sunnyvale, CA diagnosed the problem to be a faulty PTC heater and has charged me over $1100 to replace it. I beileve it is quite absurd to have a fault in the HVAC system render the whole vehicle completely immobile and useless. This seems like a serious design flaw and it could lead to serious health or safety concerns.

I experienced premature failure of all 3 modules is the vehicles PCS (Power Conversion System) part of the HV Battery System. Although a TSB was issued to replace the same part in other cars with "affected" VINs Tesla has ignored this faulty part and has declined to replace it under the vehicles HV Battery warranty even though the unit is replaced as a single unit when the HV Battery requires replacement. This is a well known issue that is being intentionally ignored by Tesla. It could leave a driver stranded in an unsafe condition or situation. I would like to see the part recalled.

The window switches on the driver window panel have deteriorated and broken not allowing the driver to pull up the windows. For a car that’s only 3 years old this should not happen and is a major safety issue as the driver has no way of controlling the windows. I have searched online regarding this issue and have found that many other owners have experienced the same exact defect that I have, most a VIN number around 30000

Our Tesla Model 3 had a failure of LV contactor which engages the HV circuit while driving the car in a 45MPH side road. The car had a sudden shutdown with emergency brakes engaged and the car came to a stop violently. It was providence that there were no vehicles following or car was not being operated in a 75MPH freeway and hence did not end up in a rear collision accident or worse involving an 18 wheeler. We talked to Tesla service and they indicated that such contactor failures occur and the car would typically behave like it did with stopping immediately as per design. I was telling Tesla service that the car should probably move into Neutral mode rather than stopping immediately. I also heard other instances where Tesla has stopped suddenly in the media. I would like Tesla to review their current logic with handling contactor failure and prevent violent and sudden stops of the vehicle to prevent accidents.

Power Conversion System (PCS) failure. This happened without warning over 60 miles from home and service center on x-range Model 3, less than 50,000 miles. Tesla did the repair, and took no responsibility for its premature failure, nor did they provide any explanation for why the failure occurred, leaving me (the owner) with a very expensive repair bill.

This is a report of suddent unintended acceleration on a 2018 Model 3 performance with 47,800 miles on the odometer - the first known occurrence on this car. At 50% state of charge, I drove the Tesla on a 10 minute trip and pulled into an underground parking garage with 3 lanes of valet parking. At about 5-10 MPH, the forward collision warning came on as I was driving towards the cones and stop sign. I brought the vehicle to a full stop with the friction brakes (not regenerative braking, which was set to LOW). The drive mode was set to HOLD, which lets the car roll forward but not backwards and doesn't CREEP when foot is off the brake. About 15-30 seconds after coming to a complete stop, my foot was hovering over the brake with maybe slight pressure up to 5%. The car suddenly lurched forward with wide open throttle type acceleration. It has over 450 electric horsepower from 2 motors. The car moved between 2 feet and 5 feet. My passenger noticed and asked what I did, if anything. I did not ever once touch the accelerator. Since my foot was on the brake pedal but not pushing hard on it, I was able to depress it with my foot and stop the car. There was a concrete wall perhaps 25 feet in front of the car. No people were in the front of the car. I was at the stop sign in the garage where valet takes over. I do not know if the car would have kept accelerating if I wasn't able to engage the brakes hard.

Interior camera malfunctions which affects the full self driving package I paid for. As purchased the car was said to be feature complete for full self driving. When the software was available to me two years after purchase the interior camera was finally turned on and it doesn’t work. A cursory internet search shows that this is common. This is a hazard it can malfunction at any time due to defective camera. The service center verified that the camera doesn’t work today 1/27/2023.

On Saturday the 21st my car had been charging overnight inside my garage using the supplied Tesla charger. As I entered the car to attempt to unlock the charger, I received many system malfunction errors on the screen, stating such that the 12v battery needed to be replaced and some system could not be completed. This definitely seemed odd as I had just replaced the 4 year old battery last July after receiving such an error. Eventually the car released the charging cable, but the car was still inoperable due to the errors. I used the Tesla app to request mobile service for the first available time, which was Tuesday the 24th, and used my wife's car in the meantime. The day of the appointment I attempted to enter the car to move it outside of the garage, but the car had completely died at some point - couldn't open doors, windows, hood or trunk. When the service tech arrived, he too thought it odd to need to replace the 12v battery so soon but continued to attempt it after jumping the car's system through the tow area. After some time, he told me the systems power up but it does not retain a charge for long, indicating a larger issue that needs to be serviced. He advised to have the car towed. I put in another service request for this, and when they arrived, we discovered that the Tow Mode accessible through the car's interface could not be engaged. They were able to skate the car onto the tow bed and transport it to the nearest service center, which I already had to pay for out of pocket ($200). The next day I received a call from the service center stating that the issue appears related to the power conversion module. Unfortunately they claimed that this was also out of pocket due to the car being out of warranty (car has just over 53k miles) and that it would cost $2000 to fix! I decided to do my own research before proceeding and discovered this was a KNOWN ISSUE by Tesla as they posted a TSB about it some time ago!
