Cruise Control Problems of Tesla Model S

The main screen stays blank and the backup camera does not work. All controls that were on the main touch screen do not function include safety features such and adaptive cruise control and emergency breaking.

While driving on the expressway, cruise control was engaged at 65-70 mph for 3-5 minutes, until suddenly, the car slowed down all by itself to around 50mph with vibration and jerking. The brake was not depressed at all. No other cars were in front of me or around me at the time of incident.

The emmc flash memory is failing, leading to the main screen blacking out for several minutes happens randomly while driving and when at stop and when the car is booting up. This prevents adjustment of several components including climate control, manual lighting, cruise control/autopilot, music it has been happening for over a month, progressively getting worse. Service came out to just reset the 12v and update the software and said everything is good but it definitely is not because its getting worse day by day.

The emmc flash memory is failing, leading to the main screen blacking out for several minutes both while driving and when at stop and when the car is booting up. This prevents adjustment of several components including climate (fans, defog, ac), manual lighting, cruise control/autopilot, etc. It has been happening for over a month, progressively getting worse. Tesla is telling us we have to replace the flash memory (~$500, but there is no guarantee the problem won't reoccur), or replace or upgrade the mcu (~$1500-2500). The car was recently upgraded to full self drive hardware (paid for in 2016) and others have reported that this contributes to the memory dying, so we contend this design flaw should be repaired by Tesla for free.

After we returned from our summer home, I tried to drive the Tesla. The main screen did not light up but I figured that a normal reset would fix the problem. As I drove, I attempted a reset but the screen remained black. I also learned that the turn signals would not work including the cruise control, windsheild wipers and headlight high beams. Worried about other problems, I returned home and have not driven the car since. Over the summer there had been several updates to the cars firmware and I was looking forward to the improvements. Prior to that. We were driving with other members of the family, all with the Tesla app on their phones. The car went into "limp home" mode on I-95 and would not respond to numerous attempts to remedy the problem. The seat heaters would turn on and off, the doors would unlock and the entire car seemed to have a mind of it's own. I asked everyone to turn off their phones and the problem disappeared. Tesla service said they'd never heard of such a thing.

This complaint is about Tesla's first generation media control unit (mcu). The mcu is the brains of the car and control the big center screen that the Tesla Model S is known for. When it failed not only did I lose the ability to use this big screen but I also lost key safety items signals, backup camera, cruise control, automatic breaking, and auto pilot. All the sound features are also disengaged as well and this was evident in the lack of sound for the turn signal as well as the lack of sound for the alert if your seatbelt is undone. Specifically in regards to the turn signal for example if you put the turn signal down to as if you are turning left the nob will lock into the down position leading you to believe your turn signal is working but unless you are outside the car you have no awareness to the fact that the signals are not blinking. In addition to this my car lost its control of the air condition and any millage tracking features were lost. The mcu completely failed on me 3 times. The first two times it came back after a few hours and the third time it never came back (was driven to the service center after 3 days and it still hadn't come back). The failed mcu allows you to continue to drive the car and you have no awareness to the safety features that are disengaged. Also, all the sensors are disengaged to me the user which stops the car from alerting me to objects ahead, behind and to either side of me. There are endless articles about the first generation mcu failures. The chips inside these cars are known to fail after a certain numbers of cycles and Tesla has yet to address this known issues leaving the consumer to fend for themselves. Please investigate these issues and hold Tesla accountable.

Total loss of display in the middle console keeps going black, total loss of turn signals, suspension control, heater controls, DE fog and DE ice, no rear camera, no cruise control, high low beams,no ability to use fog lamps. Plus many more things too numerous to list. I took it to service dept and they did a temp fix for $150 but told me it will go out again and it did the very next morning. Something to do what's called the mcu memory failing. Its gone dark on several occasions many different dates. There is no way to know when it will do it again. Makes the vehicle in my estimation more likely to get into a crash.

On June 9 at approximately 10:30pm, the car accelerated on its own at a high rate of speed. The cruise control was off, as such, so was the driver assist mode. In addition, without prompting, the sunroof opened and the windshield wipers turned on. The only way to stop it was to reboot the computer. The fact that Tesla denies this is a problem is ridiculous. There is clearly a software issue that has been recently introduced. I have had the car for more than 5 years and have never had this type of problem until now.

The contact owns a 2020 Tesla Model S. The contact stated that while driving at various speeds with the cruise control activated, the vehicle abruptly stopped independently without warning. The vehicle resumed normal operation soon after each failure. The contact had taken the vehicle to Tesla (2312 state st, south salt lake, ut 84115) where the mechanic was unable to diagnose or duplicate the failure. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 2,500.

Mcu failure (March 2020) from emmc memory wear-out resulted in non-functioning car. Car would not "turn off," thereby entirely draining batteries. Since the air conditioner was on during mcu failure, it would remain on, no matter what I did, thereby (a) running down the battery, and (b) potentially creating a maintenance or fire hazard (ac running for 12 hours). Also non-functional was cruise control, radio, rear camera, audible warnings (like turn-signal clicks), inability to control battery charging, loss of navigation, parking warning chimes, energy usage graph, cell features, etc. Significantly, the "creep" feature, which moves the car forward when pedal is lifted, also did not work -- causing me to have to relearn certain drive features, and at one point allowing the car to roll backward when it usually would have creeped forward. It's unknown if certain emergency braking features would have worked. Main vehicle control systems functioned (steering & brakes), but nothing else did, and driving was very concerning. Cost to repair was $1575. However, the same type of computer was installed, which leads to concerns that the same problem may occur in the future. See also NHTSA action number: pe20010.

I was approaching a stop sign with my foot lifted above both pedals (brake and accelerator) when my car accelerated forward. I had always thought that most of these unintended accelerations were due to a driver hitting the accelerator pedal instead of the brake pedal so I noted that my foot was not resting or pressing on either pedal. I put it down on the brake pedal and the car stopped, but this should never have happened. I had no cruise control or steering aid activated. I also have 'creep mode' turned off.

On 1/18/20, I was travelling in my 2016 Tesla Model S p100d eastward on anderson hill road toward the intersection with purchase street. The stop light was red. I was driving 1mi under the speed limit of 35mph. The outside temperature was around freezing, and a wet snow had begun 5-10min earlier, with minimal accumulation. I know exactly how fast I was going because I had cruise control on. I was not on autopilot. Just cruise control. When the intersection and stop light came into view, I tapped the break to disengage the cruise control, and then depressed the break to slow the car. Nothing happened. The breaks would not engage. And neither did the regenerative breaking. I do not feel that I was skidding or sliding. It simply felt as if the car had no idea I wanted to brake. It was very very strange. In those few seconds it became clear to me there was a good chance I would be dead shortly. As it happens, I was struck broadside by a large suburban travelling northbound on purchase street perhaps 25 miles an hour. Both he and I seem to have emerged relatively unscathed (physically, anyway) thank god. But I want to know what happened to my car. Can you please contact Tesla and demand all the information from the cars computers - and their computers at hq - so we can find out??? what happened was extremely dangerous, and could have killed both me nd others. To summarize: brake failure, both manual and degenerative, in 2016 Tesla Model S caused massive collision with both cars totalled.

Driving on a 2 lane highway using autopilot the car accelerated and pulled left, ended up in the opposite lane and almost off road over a cliff. This is not the first incident I had with my Tesla. On several occasions, while using cruise control, it suddenly braked in the middle of the highway, while the immediate collision alarm went off. There were no vehicles in front of mine and no immediate risk for collision. Tesla needs to improve the autopilot features as there are significant safety concerns.

Cause unknown. The vehicle was stopped just before entering into a head in parking space when with the brake depressed, the vehicle accelerated suddenly and uncontrollably causing it to jump the curb and take down a retaining wall. It continued through the wall until it was stopped by a tree. Vehicle was a total loss. Vehicle settings at the time of incident were as follows: there is no autopilot on this Model S and cruise control was off. Additionally, the car was set with creep mode off. Hvac was on.

Failure of vehicle to engage automatic emergency braking or apply adaptive cruise control braking in repsonse to a vehicle abruptly stopping ahead. Vehicle had adaptive cruise engaged at 57 mph on interstate highway and an acc sensitivity of 2. Vehicle forward collision warning did alert. This failure resulted in a rear-end collision with the car ahead.

With the current release v9, in a specific location, under autopilot the vehicle attempts to suddenly veer off the road to the right, in a violent action. Manually correcting causes autosteer to disengage but cruise control remains on exasserbating the situation. Conditions: 2 lane highway, traveling at 45 mph. Painted center line jogs slightly to accommodate center turning lane. Travelled this road safely on autopilot for over a year without incident. Now it happens everytime. Attempts to contact Tesla, thus far have resulted in no response.

This Sunday may 20 I was driving my Tesla Model S southbound on route 1 in rehoboth to work in autopilot mode. I had this feature of my vehicle set to 50 mph. If you aren't familiar with autopilot in Tesla's, let me explain how it works. Once the vehicle indicates the feature can be activated, you press a button as you would any other vehicle with basic cruise control, and the car will literally accelerate, decelerate, and steer itself without further input from the driver. While using this feature of my vehicle, I had a significant accident on route 1. As I said, my vehicle was traveling at a rate of 50 mph. I was driving in the left lane southbound with autopilot activated. In turnabout in the median, a white pickup was perpendicular to my car with sticking out about 1 ft into my lane. The left side of my car skimmed the back of his car without slowing down. Autopilot failed to recognize the car was there. I am lucky I wasn't killed, and I am lucky no one else was hurt. This accident has shaken me up quite a bit. Now, I do not blame Tesla 100% for this auto accident; I don't plan to file a legal claim against them or anything like that. In fact, I plan on replacing my vehicle with another Tesla (without the said autopilot features) but I would be doing a disservice to anyone without trying to use this experience of mine to hopefully save lives in the future. I brought these exact issues up with Tesla regarding my accident several times to several different departments and my concerns have been totally dismissed. If regulation for features like these in vehicles is not implemented, unfortunately I have no doubt in my mind people will be hurt and possibly killed,.

The contact owns a 2018 Tesla Model S. While attempting to park the vehicle, it independently accelerated and crashed into a wall. The air bags deployed. A police report was not filed. The contact sought medical attention ten days later for a sternal fracture. The Tesla buena park dealer (6692 auto center dr. , buena park, CA 90621, (714) 735-5696) was contacted and the vehicle was towed to a Tesla approved facility to be diagnosed. The contact was informed that the on board diagnostic testing reported that the accelerator pedal was depressed at the time of the crash. The contact was also informed that the automated features, including the cruise control were unable to have induced the accelerated response. The vehicle was not repaired. The manufacturer was also notified of the failure. The approximate failure mileage was 214.
