2018 Tesla Model S electrical complaints
Page 2 of 2: complaints 11 to 35 of 35, newest first, as owners wrote them.
Second door handle has failed and no longer unlatches door from outside, therefore dangerous to be unable to reach the back seats
I was pulling into my driveway and beginning to pull into the garage. Immediately after straightening the car out to fit the space in the garage, the car immediately launched itself, accelerating extremely quick with no chance to brake or brace for impact. The car and the house suffered damage and I’m currently awaiting MRI results for possible injuries. It was an evident malfunction in the car’s system.
The contact owns a 2018 Tesla Model S. The contact stated that while the vehicle was at a complete stop, he activated the Auto Park feature to park the vehicle. The vehicle unexpectedly rolled forward and crashed into another vehicle next to his front passenger's side. The contact stated that it was a minor collision and that no police report was filed. The contact was able to drive the vehicle away from the scene. The vehicle was taken to a body shop, where it was diagnosed that an unknown part near the passenger's side front wheel needed to be replaced. The vehicle was not yet repaired. The manufacturer was made aware of the failure and confirmed that the Auto Park feature was activated; however, the Auto Park inadvertently disengaged, causing the vehicle to roll. The failure mileage was approximately 10,000.
Component that failed is daylight running lights and is available for inspection. Daylight running lights are important to be seen easier by other vehicles and pedestrians, since they don’t work my vehicles is more difficult to be seen during the day. Confirmed by service center. Unknown if inspected by manufacturer, police, insurance representatives or others, most likely not. No warning lights, no messages, no symptoms, first appeared approximately sept 2022
MCU2 Failure. Dashboard and Screen no longer works Turn signals and headlights do not work There are no seatbelt warning Can no longer see battery levels / range (via app or inside car) Can no longer see car's location (via app) The car will drive, brake lights and windows work THAT'S IT. Car it totally unsafe to drive otherwise. Tesla is charging $1965.75 plus taxes which equals $2083.70 Parts $1800 Remove and Replaces $165.75
The contact had rented a 2018 Tesla Model S. The contact stated that while his wife was making a U-turn at a low rate of speed, the vehicle accelerated with her foot on the brake pedal and crashed into a tree. The contact stated that his wife heard two warning beeps prior to the failure which the contact stated it signaled that the autopilot had independently engaged. The air bags did not deploy during the accident. The contact's wife did not suffer any injuries. A police report was filed. The vehicle was towed to an independent mechanic where it remained in their possession. The rental company had yet to receive a diagnosis as to the cause of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 44,000.
The contact owns a 2018 Tesla Model S. The contact stated that while driving at an undisclosed speed with the Self-Driving feature activated, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 36,000.
Vehicle will routinely reboot while driving. During this time the turn signals, speed information and other vehicle information is not available while driving.
Three of four (3/4) of door handles failed simultaneously. Doors failed to open resulting in inoperable doors. Driver’s door suffered random catastrophic failure, resulting in door abruptly opening while in motion. Brought to Tesla service center and notified that parts are on back order. With no other solution. Primary safety concern is door will randomly open again during operation. Service center could not offer alternate solution to securing or operating doors. Only solution until parts are received is to access doors from inside the vehicle through the one single operable door. This is a potential entrapment and major safety issue.
On Sunday, October 10th. I arrived at a friends home in Charleston S.C. with about 35 Miles left on the Odometer. In the AM I awoke to find only 5 miles left. As I knew that I was 21 miles away from a Tesla Supercharger I called for a tow truck, and paid $265 to get taken to the charge site. I hooked up and the car began to charge. When I was close to capacity I disconnected - and the charge dropped to zero. I called Tesla. They sent a tow truck and took me to Savannah Ga. Tesla (80 miles south....no charge). 7 weeks later - on Dec 1st...I got my Tesla back from Savannah Ga. Tesla. Immediately I got a warning "Power reduced - service required". I called and arranged for service (set up for Dec 14...two weeks away). This morning I got a similar message; 'Coolant for battery low - Service required" (see image, below)
The contact owns a 2018 Tesla Model S. The contact stated while driving at various speeds, the instrument cluster and home screen was intermittently inoperable. The contact called a service center on several occasions and was informed that the failure was linked to a software update and a full onboard computer folder. Despite the repair, the failure persisted. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.
Touch screen goes disabling all visual communication, including air conditioning, rear camera, GPS. Occurs while driving, and while parked (several times on start up). Have notified tesla several months ago, but have been told not to schedule replacement as they are short on parts.
My september 2018 build tesla model s experiences the same screen failures (both the dash + media control unit) as the recalled versions, but mine falls outside of the recall period. The latest incident occurred while I was driving on a desolate highway traveling at 85 MPH. I lose my speedometer as well as features such GPS which occurred once in an unfamiliar area.
The main console center screen in my would stop responding and will basically freeze up. The indicator clicker sound would stop working. The navigation system would remain stuck. The air conditioner would stop working. All these are happening while the driving. I have to reboot the screen by holding the 2 scroll buttons down and then the screen would go dark for 10 min before it starts working. I have bought this to service few times and they don't do anything saying everything is just fine.
The vehicle downloaded tesla update on 12/27/20202. The firmware version is 2020.48.26. After the update was installed, the instrument panel above the steering wheel had very small illegible font. For example, the transmission shift indicator letters (p, d, r) were too small to read which is critical. Mph, and percentage of power remaining were also near illegible as well.
This relates to a tesla warranty adjustment program notice issued november 09, 2020. There is a malfunctioning of a memory chip (embedded multimediacard which causes the screen to freeze or blackout or get fuzzy and does not allow you to make or save changes to the vehicle control touch screen. My car was reset to faculty default on november 23, 2020, without changing the chip, and the next day it failed again. I have scheduled a service visit for december 02 2020 with the expectation that the faulty chip will be replaced. Previously my screen had a yellow border that appeared from nowhere and the tesla service team used some sort of uv light to remedy the situation in june of 2020. At that time they told me if the yellow border reappears then the screen will need to be changed. At the june 2020 service visit they apparently also replaced, at no charge, a computer component. The screen failure I am reporting today began shortly after the june 2020 components were changed, approximately first noticed august 1, 2020. My ongoing concern is that this problem needs to be fully vetted and repaired during the warranty period as these components are quite expensive. Tesla owes its customers a definite fix of the screen and the onboard computer problems, and an assurance that the clock will restart on any repairs made under warranty (what I am proposing is that tesla does a good faith extension of certain of the vehicle's components so that customers are covered for problems not related to normal wear and tear for a reasonable period of time). Thank you.
I dropped my personal tesla at tesla service to get an mcu/center screen failure repaired. As I left the lot, the screen in the loaner car rebooted itself. Apparently that is the precursor to failure. It feels weird knowing this car is probably about to fail the way mine did.
The touch screen has become completely unresponsive/went dark. I first discovered the problem while the car was parked in the garage, infrequently used. This has been the case for the last 4 weeks, also rendering the mobile app unresponsive/unable to connect to my car. As a result, the AC has been stuck on, running continuously for a month since this issue started. My tesla service appt. Has been delayed twice due to replacement parts unavailable. This new article seems to describe the same problem my car (and others with the same model) is/are experiencing: https://apple.news/a3rf2d8agqo6j-cettn354g.
Tl* the contact owns a 2018 tesla model s. The contact stated that while driving at very slow speed and parking, the vehicle suddenly experienced unintended acceleration causing the driver to lose control of the steering and crash into a transformer. No injuries were reported. A police report was taken at the scene. The vehicle was towed away. The cause of the failure was not determined. The local dealer tesla of honolulu (1450 ala moana blvd, honolulu hi) was notified of the failure. The contact stated that after the vehicle was repaired the same failure had occurred while parking causing the driver to lose control of the vehicle and crash into a concrete wall. During the crash the driver sustained a chest injury due to the air bag deploying which required medical treatment. No police report was taken. The vehicle was towed away. The cause of the failure was not determined. The contact also stated that while driving the instrument display pad had suddenly blacked out on multiple occasions and the doors had failed to open on several occasions. The cause of the failures were not determined. The failure mileage was 7,410. Owner is extremely scared to drive again. Car is sitting in the garage. Worried about anyone driving the car may get into a fatal accident.*dt
Tl* the contact owns a 2018 tesla model s. The contact stated that while still seated in the vehicle in the driveway after the vehicle was stopped and the gear shift lever placed in the park position, the front seat passenger attempted to exit the vehicle and the vehicle accelerated independently. The vehicle crashed into the vehicle parked in front. The vehicle then independently reversed and crashed into a tree. The vehicle eventually came to a stop after the contact released the brake pedal. Both the passenger and the driver exited the vehicle without injuries. A police report was not filed. The contact stated that the other vehicle sustained major body damage. The dealer and manufacturer were not notified of the failure. The failure mileage was 7,700.
Twice recently while driving on highway at night, the car computer started failing. Lights went out, turn signals didn't work, eventually the whole screen and dashboard that let you drive turned blank. I had to find a way to quickly pull to the side of the road and reset the car by pressing and holding the two buttons on steering wheel. This is a very unsafe condition.
On at least 2 occasions, while driving the car, the electrical system stopped working. One time, the car just shut down at a stop sign nearby my office; the second time, while driving on the highway, the car continued to run but all of the other electrons: speedometer, turn signals, radio stopped working. When I pulled over, the entire car shut down. Both instances required a "hard stop" to re-start the car. The dealer informed me that this can happen when the software has not been recently updated. However, you need wi-fi to update the software and it is not readily available where I reside and park my car. I consider this situation extremely dangerous in that the car can spontaneously shut down while in use. I am taking the car into the dealer today-probably so they can upgrade the software on site. However, this does not address future potential issues with the car. I do not have the ability to routinely take the car into the dealership for upgrades. Further, there is no message from tesla when the upgrades are available. Please help. I really have no desire to die when the car stops working while driving it!
Car was stopped prior to entering car garage. Car suddenly reversed then sped up autonomously and crashed into the home. Suspect car electronics compromised and endangered driver. Requesting investigation if car defect vs user error. Thank you !
Tl* the contact owns a 2018 tesla model s. While approaching a red light, the speed increased and the vehicle failed to respond when the brake pedal was depressed. The vehicle drove through the traffic light and crashed into a vehicle that was making a left turn. The front driver's air bag and knee air bags deployed. The front driver's side curtain air bags had not deployed. The driver sustained shoulder and back injuries that required medical attention. A police report was filed. The insurance company towed the vehicle to a collision repair facility. The dealer (san diego miramar tesla, 9250 trade pl, san diego, ca 92121, (858) 271-5100) was notified of the crash and the contact was waiting for feedback from the insurance company. The dealer and the manufacturer were waiting to retrieve the information from the electronic data recorder to investigate the cause of the failure. The approximate failure mileage was 49. *bf
