2021 Tesla Model Y complaints

Very often when "autopilot" or "traffic aware cruise control" are activated on two lane roads (county or state highways) and there is oncoming traffic the system will alarm and brake hard as though the car is about to have a head on collision. This is a safety hazard because if anyone is following me when this happens it would be very easy to get rear-ended. This problem has been happening since I purchased the car and has been reported to Tesla 4 times along with videos of the incidents and they refuse to fix it.

This is our second Tesla, so I am familiar with the function of adaptive cruise control and autopilot. Vehicle frequently initiates hard braking events without warning or cause on the highway. I have contacted Tesla service, and they are stating that the car functions normally, and that this is normal behavior. If this is normal behavior, it is definitely unsafe. I have almost been rear ended several times.

Sudden acceleration while stopped. Car was stopped in the driveway of my home while waiting for the garage door to open. Suddenly the car bolted forward, crashed through the rising garage door and then through the side of the garage and into the front steps of my home. The car is equiped with auto pilot, but it was not engaged. While reviewing other incidents of this type on your website, I noticed that other people mentioned their Tesla's having the autopilot feature but I saw no mention of the Model Y. Although extensive damage happened to the car and my home, no one was injured. However if this had happened while at a stop light or at a crosswalk someone could have been killed or injured. My Insurance Co. did not seem interested in investigating this event, haven't heard back from Tesla.

The contact owns a 2021 Tesla Model Y. The contact stated while driving 50-70 MPH on cruise control, the vehicle would inadvertently decelerate, almost causing other vehicles to crash into the rear of the vehicle. There were no warning lights illuminated. The contact also stated that the vehicle was designed with no radars and was built with camera vision instead. The manufacturer was made aware of the failure but did not provide any assistance. The contact stated that the failure had been reoccurring more frequently. The vehicle was not diagnosed or repaired. The approximate failure mileage was 20.

While using Tesla Autopilot, I’m receiving significant “phantom breaking” events where the vehicle, for no apparent reason, applies the breaks, quickly and unexpectedly decelerating at highway speeds.

Tesla delivered a car with a concerning mechanical defect on all four hinges of both rear/forward doors. There are deep gouges to the metal on all four hinges. They have no explanation as to why the metal that holds the doors I place has been damaged. Multiple calls to Tesla has resulted in them saying they will absolutely not look at the issues on the car until December 10th. They said that I can't even bring it in to a service center for safety inspection. I wanted to reject delivery and get a safer car but they said that I would then not receive a car for 4-6 months later. Meanwhile they had already accepted payment, so I would be on the hook for payments. I don't know if these.doors are safe, I'm looking for a Tesla to say whether the car is safe to drive or not, and find out what caused the damage. Tesla will only tell me that they will look at the car in December.

The car will hard brakes all the time on autopilot. I've had it occur going up slight hills, the sun being out, rounding bends, etc.

I had 2 accidents both caused by the wheel forcefully turning and not letting me take over. First incident: On 8/31/21 I was driving on the right lane of the palisades pkwy S (NJ) the car was on “autopilot” my hands where on the steering wheel. It was raining, there was no car around me for at least a few hundred feet. Suddenly the “forward collision warning” started beeping, and I felt the steering wheel is forcing itself very sharply to the left, I tried turning back to the right, but I couldn’t. Fearing that the car will end up in the lane of the opposite traffic, I slammed the breaks. The car ended up doing a 180 hitting the dividing guardrail against oncoming traffic. The car was towed to a shop where it was until oct 18 when it was ready for pickup, damage costed about 15k to repair. There was no injuries, and no other car involved. Second incident: On oct 26 A week after I picked up the car from the repair shop, I was driving on the NJ Turnpike N on the left most lane. It was raining, and the car drove over a small puddle of water. Suddenly I felt the steering wheel turning very forcefully to the right. I tried pulling back to the left, but was unable. it felt as if the steering wheel was locked, causing the car to abruptly make a hairpin curve, bypassing the next lane, and hit a car two lanes over. From the impact the car was thrown back to the left, knocked into the highway divider, the car then spun and flew all the way to the other side of the highway. This time th

Our 2021 Model Y features the new vision based cruise control system, both traffic aware cruise control and autopilot utilize this camera only system. At the time of ordering we were under the impression we were getting a much safer and mature radar based system. Upon accepting delivery at the end of May we have accumulated 9,000 miles on the car and have a had horrible experiences with the traffic aware cruise control slamming on the brakes for no apparent reason with nothing ahead or passing cars. Behavior can be 5-10mph slowdowns or in some cases FULL brake pressure which puts us in danger of being rear ended. Multiple times we have been close to rear ended. In addition the system can also produce audible beeps when cars pass however no warning or message is displayed. I want to stress this behavior is a daily occurrence day or night. We have reached out to Tesla in order to get the vehicle looked at for repairs and have a been denied even a service appointment. The vehicle was declared fine hardware wise. I documented our experiences in just one evening of driving and put together this YouTube video showing the behavior. https://www.youtube.com/watch?v=20ETPyzjc_U As referenced in the video below Tesla explains the cruise control is BETA and to be ready to take over at any moment. I take great exception to the practice Tesla is utilizing of declaring previously standard features "BETA" and making customers deal with their poor results with no accountability. We don't acce

While driving using cruise control the vehicle will occasionally brake suddenly for unknown reasons. In one instance I was worried that the car following me would either hit my car or be forced to take other action possibly causing an accident. When I contacted Tesla regarding my concern they said something about the software program evolving…no fix available. The cruise control system is Dangerous. There is NO warning, you are traveling down the highway, all seems fine, and then for no apparent reason the car applies the brakes so hard that everyone in the vehicle is startled and vehicle behind you sounds their horn!

The contact owns a 2021 Tesla Model Y. The contact stated while driving at various speeds, the vehicle would experience random braking without input from the driver. The contact stated no warning lights were illuminated. The vehicle was taken to a local dealer but was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 6,450

The Vehicle was in FSD Beta mode and while taking a left turn the car went into the wrong lane and I was hit by another driver in the lane next to my lane. the car gave an alert 1/2 way through the turn so I tried to turn the wheel to avoid it from going into the wrong lane but the car by itself took control and forced itself into the incorrect lane creating an unsafe maneuver putting everyone involved at risk. car is severely damaged on the driver side.

Sudden, hard self breaking when in autopilot mode. Danger of collision at high speeds.

Since purchasing the car less than a month ago, there have been over 100 phantom braking events while using cruise control. The vehicle will suddenly SLAM on the brakes with no apparent reason, even when there are semi trucks following closely behind. The only way I have avoided rear end accidents is by emergency presssing the accelerator. It is incredibly dangerous.

Vehicle applies brakes suddenly while cruise control is active at highway speeds, for no discernible reason. This happens extremely often and has almost caused the person following to rear end me on multiple occasions

While driving on well marked highways, the adaptive cruise control would initiate rapid and unsafe braking while using the vehicles “AutoPilot”. The braking is equivalent to a user putting full pressure on a brake pedal, losing 10-20mph by the time I am able to intervene, even if I’m ready to take over. Such rapid deceleration leaves me vulnerable to a rear collision from following drivers There is no warning, and no alarms from the vehicle. The manufacturer has no specific response, other than advising a system reset. The system reset does not solve the problem.

Two issues: 1) alarming clunking noise coming from suspension. 2) center command screen froze and then crashed completely (black screen) while driving, which resulted in a loss of controls like turn signals and speed indicator.

In Feb. 2021 I purchased a new 2021 Tesla Model Y. In August I noticed a crack in the glass ceiling originating from the front edge of glass. We made an appt for 10/19 to have it replaced at the S. Seattle Tesla Service Ctr, assuming the repair would be covered under warranty. We brought the car in on Oct 19. The service rep inspected the crack and very quickly determined that the crack was a result of something hitting the ceiling such as a small rock. The rep's eagerness with her response suggested that she was familiar with this issue and was ready to deny warranty coverage. She told us we should make a claim against our auto insurance policy. We countered that we didn't believe anything had hit the ceiling, and even if it had, the glass should not have cracked that easily. Also, we also pointed out that in all the other cars we've owned we have never experienced rocks being spun up from the road hitting the ceiling. The rep still declined. We went ahead with the repair. We searched the internet for other Tesla owners whose ceiling glass had also cracked and found a number of postings on several forums of customers who had the same disappointing experience we had. It is evident that there is some kind of design flaw that results in the ceiling glass cracking easily. We inquired with a class action law firm who informed us that there is a provision in Tesla's standard warranty in which the consumer agrees not to enter into any class action lawsuits against Tesla and require

What component or system failed or malfunctioned, and is it available for inspection upon request? The Dashboard and yes. How was your safety or the safety of others put at risk? car display has unexpectedly rebooted while I was driving, my display rebooted. It crashed when my passenger was attempting to read the release notes while I was driving. It was night, and after it rebooted, the part of the screen that shows the car and road flashed white, blinding me while driving. I lost the ability to signal or determine if it's signaling, no speed indicator no anything, not even a signal sound. I couldn't control the windshield wiper, when I attempted to turn on the emergency blinkers, I had no visual or audio confirmation that it was working. this lasted for 1-2 minutes. Has the problem been reproduced or confirmed by a dealer or independent service center? No as the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No

I was driving in cruise control at the posted speed limit of 80mph. The conditions were dry and sunny. Without warning the car braked hard and decelerated from 80mph to 69mph in less than a second. The braking was so violent, my head snapped forward and I almost lost control of the car. This 'phantom' braking occurred other times but it was less sever. The unpredictable nature of the adaptive cruise control and emergency braking has prompted me to disable these so-called safety features.

At random times, without warning, cruise control changes from set speed (e.g. 70mph) to 45mph and vehicle immediately begins hard braking to achieve new set speed. Any cars following may not be able to react quickly enough to avoid a collision if the driver doesn't react quickly enough to command acceleration back to freeway speed. I sent multiple videos of this happening to Tesla's service department. Tesla virtual service has looked at vehicle's logs and says there's nothing wrong with the vehicle and that it must be in how the vehicle is interpreting fleet data and map data. Clearly a software bug not validating it's input for reasonableness. No audible warning and while the cruise set speed does change on the display, the deceleration happens simultaneously, so no actionable visual warning is given to prevent the uncommanded deceleration and one must react immediately.

Tesla has dog mode, camping mode, and climate on mode, which shows the interior temperature on the screen and in the app. The Telsa was in "dog mode" and displayed on the screen and app that the interior of the car was 66 degrees, but A/C was clearly not on and the interior of the car measured near 100 degrees. If I had not checked on the dogs in the car immediately, they would have died.

The contact owns a 2021 Tesla Model Y. The contact stated that the safety restraint system alert was displayed. The vehicle was taken to the local dealer on several occasions, but vehicle was not diagnosed or repaired. The manufacturer was notified via email but had not responded. The failure mileage was unknown.

My car brakes for no apparent reason when cruis control is active of autopilot. Sometime it is about sometimes it is gradual. In one instance on the interstate at 75mph it took me down to 50 befor I could hit the accelerator petal to make it continue. This is a hazard for drivers around me. I have been in contact with tesla multiple time but they have done nothing to fix it. Lane keep assist is also an issue. When the lane keep assist is turned off in the settings it will still preform the lane keeping. This caught me off guard and caused damage to the vehicle.

The contact owns a 2021 Tesla Model Y. The contact stated while driving at various speeds, the vehicle would slow down without warning while using the smart cruise control feature. The contact stated no warning light was illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 3,000

Car started violently shaking at 70mph on the highway, almost lost control of the car and hitting the divider, took it to the tire shop they said could be a balance issue looked harder to realer the foam from inside the tire fell apart 255/40r/20

The car has less than 300 miles on it and I hear a loud clunk under the front of the floor by the pedals as if something is loose like the front motor or the suspension.

This 2021 Tesla Model Y struck and killed a motorist who was outside of his disabled vehicle with the hazard flashers functioning on the motorist's vehicle. I represent the wife of the deceased. You are already investigating this accident as part of a larger investigation. See article below. The wife of the deceased, [XXX] , was on the phone with him when he was struck and killed and is a witness who you would likely want to interview as part of your investigation. I also am in possession of the disabled vehicle in an unaltered state and available for your Investigators to inspect. Please contact me on my cell phone at [XXX] . [XXX] Sincerely, [XXX] , Esq.

What component or system failed or malfunctioned, and is it available for inspection upon request? Adaptive cruise control is unusable on small 2 lane hwy. How was your safety or the safety of others put at risk? Car would brake hard by itself without any obstacle for miles in front of the car. It also brakes randomly following another car or if it detects traffic on the opposite lane. Car would also brake randomly if there was another vehicle behind which almost caused an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? Problem was acknowledge by Tesla customer support via the issue reporting app. They downloaded my trip data. However I was told that it wasn't a hardware issue but a software issue. They will issue a fix however it has been 4 months with no fix insight. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No I was told there was no issue with hardware. I have no reported this issue with police or insurance since there was no accident. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lamp.

While leaving a parking lot, the vehicle lurched and felt like anti lock brakes kicked in and the car stopped working. The monitor had multiple alerts including saying to get out and back in the vehicle and it may allow me to resume driving. It did not. The vehicle stopped and just would not allow me to drive, pull over or move the car in any way. The park, neutral, drive options were gone. If I were on a highway I most likely would have caused multiple accidents. Extremely scary and not normal. Seems like other tesla forums call this issue out for numerous other people. Something needs to be done.

The contact owned a 2021 Tesla Model Y. The contact stated that while driving approximately 70 mph but doesn't recall; the vehicle began shifting from left to right for 5 - 10 seconds when another vehicle approached the passenger side of the contact's vehicle. The contact attempted to disable the autopilot by depressing on the brake pedal and maneuvering the steering wheel however, the vehicle would not allow the contact to control it and it spun around and hit the median wall on the highway. Medical attention was received on the scene for the contact's sister, who was a passenger. A police report was filed. The vehicle was towed to a Tesla repair center, where there's an ongoing investigation. The manufacturer was made aware of the failure and informed the contact that they would respond within 6-8 weeks after the investigation. The failure mileage was approximately 300.

I was using the smart summon function to reverse my car parked under a parking roof held on pillars. When using the summon, the Tesla wheels rotated before it had reversed enough to be away from the pillar and scratched the side wall against it. Tesla refused to cover it under warranty even though there was no way I could have prevented it because it happened as soon as the car started reversing.

Backing out of garage, the driver began to smell acid and burnt electronics from the back of car. After driving back home from work the driver inspected the car. The back driver side door reeked of burnt electronics and the entire car had an acid smell. After consulting Tesla, the first Tesla maintenance worker noticed the entire inside of the door had melted and all electronics were fried. He claimed he had never seen this before. The second maintenance worker came with parts and determined the window module had overheated and caught fire. The fire melted many components inside the door. A brand new 2021 Tesla Model Y should not spontaneously catch fire. Especially if it is residing inside the garage of a house. After replacing all the components, Tesla deemed the car safe to drive. Yet, a couple days later they requested we bring the car in so that they could replace the computer that controls the left side of the car to do more research and find the 'root' cause of the fire. There were no warnings for the driver, nor was the driver using that window module. We have not driven the car since as we feel unsafe in the vehicle.

The contact owns a 2021 Tesla Model Y. The contact stated while driving approximately 60-70 mph and merging onto the highway, the vehicle inadvertently swerved into the two other lanes. The display screen (eMMC) crashed. The contact attempted to reboot the system however, the touch screen failed to respond to the touch. The vehicle was taken to the dealer, but the dealer could not duplicate the failure and informed the contact that everything was fine with the vehicle. The failure recurred. The vehicle was taken to another dealer Tesla (3067 N Elston Ave, Chicago, IL 60618) and after the dealer test drove the vehicle, the mechanic found out that there was a firmware bug that caused the failure. The dealer informed the contact that he needed to wait for the software update in order to resolve the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 8,500.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at 65 mph, the steering wheel seized and the brakes failed to engaged. The vehicle went into autocorrect on its own and was swerving then crashed into a semi truck. No medical attention was received on the scene but the contact later seeked medical attention. A police report was filed. The vehicle was towed to a Tesla approved collision repair center. The dealer was made aware of the failure and informed the contact that they will escalate the file over to headquarter to evaluate. The failure mileage was approximately 2,800.

I purchased the Tesla Full Self-Driving capability via subscription for my 2021 Tesla Model Y on Saturday, July 17, 2021. On Sunday, July 18, 2021 at approximately 12:40pm CT. while activating the Smart Summon feature in a private residential parking lot, the car drove itself into a tree damaging the front of the car resulting in a total cost of $1,799.32. Tesla is refusing to refund me the $200.00 for the Self-Driving subscription after their software malfunctioned. This is a dangerous feature that is available to millions of drivers. Video footage of the incident is here: https://vimeo.com/580859343 This is the description of Smart Summoned directly from Tesla’s website: https://www.tesla.com/support/autopilot#usingautopilot Smart Summon is designed to allow your car to drive to you or a location of your choosing, maneuvering around and stopping for objects as necessary. Like Summon, Smart Summon is only intended for use in private parking lots and driveways. You are still responsible for your car and must monitor it and its surroundings at all times and be within your line of sight because it may not detect all obstacles. Be especially careful around quick moving people, bicycles and cars. To use Smart Summon, open your Tesla app, tap Summon and then select the Smart Summon icon. To activate the feature, press and hold the COME TO ME button. Alternatively, tap the target icon, set the target destination of your choice by adjusting the map, and then press and hold the GO TO

There is no mechanical release for the rear doors. If the vehicle loses power you cannot exit through the back doors. In a crash where the Model Y completely loses power, rear seat occupants cannot get out on their own.

I pulled up next to a parking space in a parking lot and the Tesla auto park feature was offered on the screen after detecting the parking spot. I pressed to auto park and the tesla proceeded to perform the auto park. During the parking the tesla hit the truck parked in front of the tesla while turning into the space and broke the taillight of the truck and scratched the tesla on right front side. I then braked and disable the auto park after the collision. I reported the incident to Tesla and they reported back that they don't see any issues with the sensors at that time and they say I need to take full responsibility. I cannot think of anything that was particularly challenging for this parking spot or surroundings. It seems a bad calculation by the sensors of Tesla or the software and it made a mistake. Given this experience I cannot trust any of Tesla autopilot features now. They have concluded they will not do anything about it.

The contact's sister owns a 2021 Tesla Model Y. The contact stated that while her sister was driving on the highway(speed unknown) with the autopilot engaged, an 18-wheeler drifted into her lane and hit her vehicle. Due to the impact, her sister's vehicle hit another vehicle and bounced back and forth between both vehicles. The vehicle continued to the drive despite the accident and no warning lights illuminated on the instrument panel. The airbags also failed to deploy. A police report was filed. The contact's sister and her mother, the passenger in the vehicle, were taken to the emergency room where they were treated for various body aches and bruising. The whereabouts of the other drivers involved in the accident were unknown. The vehicle was towed to an independent tow yard where it remained in their possession. The dealer nor the manufacturer have yet to be notified of the failure. The vehicle had yet to be repaired or destroyed. The failure mileage was approximately 2,000.

This problem happens repeatedly. It has been reported by multiple Tesla owners but no action has been taken by Tesla. When driving with the cruise control engaged, the car will brake very aggressively. This happens most commonly when there is no other traffic on the road and no debris on the road. It seems the car believes there is something in front of the car for which it needs to stop, even though the road is clear. But if I press on the accelerator the car resumes normal cruise operation. If there is a car behind me I am worried that the car behind me will crash into me. The braking action is VERY aggressive.

An independent tire shop and Tesla both told me my rear passenger wheel is bent. The tire on that wheel has been slowly bleeding air for the last month or so. This vehicle has 9500 miles and is not driven recklessly whatsoever. The wheel is available for inspection - I have swapped it off for another. The vehicle now shakes when driven at highway speeds and is a problem that Tesla and an independent tire store have both been unable to remedy. No warning lamps/lights/signals appear. This shaking suddenly started on 7/5, 2-3 weeks after the tire started bleeding air.

My car's rear windshield got shattered on its own. It was parked outside more than 16 hours and its windshield broke on its own when no-one was inside the vehicle. When it shattered, we were near car only. This would have been disastrous if someone was sitting in the 3rd seat row, it could have fallen on them or would have impacted driving due to shattering noise. Vehicle inspection is still not completed by manufacturer. There was no other damage to windshield or no stone or any object was hit it. There were other people also around and they saw it got shattered on its own. I would be able to provide videos and photographs of the damage.

On 5/5/2021 my wife was driving in the Tesla Y taking her two grandkids to school and was stopped at a traffic light. The car was in Hold mode with a car in front of her and a car behind her. The car does not have Auto Pilot. All of a sudden the car started moving forward in an accelerated mode. My wife did not push the accelerator. The Tesla hit the car in front and then went into reverse and hit the car behind. Substantial damage to all three cars. My wife and my grandkids were terrified and everyone started screaming. My wife couldn’t release her seatbelt because it tightened during the crashes. She had to call for help. This happened at 7:30am. The San Jose police took a report 21-125-0191.

Phantom braking is a known problem with the Tesla Model Y. My adaptive cruise control has malfunctioned 2 times in 1 week. It's a very dangerous situation. Apply panic braking when the road has very little traffic and no curves. No warning signs at all. I reported the 2 incidents to Tesla. They essentially said that there was nothing they could do.

I had turned into the Taco Bell address: 5217 Mudd Tavern Rd, Woodford, VA 22580 when the car surged and sped. I was able to avoid a person and the dog. But the car continued to accelerate. I tried to utilize the brake system but it did not engage and continued speeding into the next parking lot address 5217 Mudd Tavern Road, Woodford, VA 22580. The car did not stop for trees and so I had to stop the car by impact with a dumpster in the Best Western Plus parking lot. This happened on June 5th 2021. I have tried to get the video from the hotel but to no avail. The Senior Deputy is [XXX] Spotsylvania county. They have the scene photographs. His email is [XXX]. Phone [XXX] ext 3936. The case file number is [XXX]. Over the last 40 years of driving my records are excellent. I really would like to understand the reason for the crash. I am not getting any assistance in a rapid manner to determine the cause. Since I have driven multiple car type over the years I need to understand why this car caused this. Hoping nobody else has to go through this. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I was changing lanes on the highway and my tire flew off the vehicle. Car lost control and slammed between railing and a large truck multiple times. Airbags did not deploy. Defective vehicle!

The contact owns a 2021 Tesla Model Y equipped with Continental Pro Contact RX tires, Tire Size 5255/4R/19XL(N/A). While driving at approximately 60 MPH, the contact stated that the front driver side tire popped as the low air pressure warning light appeared on the instrument panel. The contact pulled the vehicle over and had the vehicle towed to an independent tire mechanic. The mechanic could not determine the cause of the tire failure and did not have the proper tire size to replace the defective tire. The tire mechanic was finally able to order the tire from another city and repaired the tire nearly a week after the initial failure. The vehicle manufacturer was notified of the failure. The vehicle had been repaired. The tire failure mileage was approximately 2,000.

On June, 4th, 2021 in the morning I went to Markham Park with my 13 year old daughter for the covid vaccine. We arrived and right after the shot on her we stopped our Tesla in a line where we should wait for about 15/20 minutes to see if everything was fine with my daughter. While the car was stopped in the line, I was talking to my daughter and the car started moving in the direction of the car in front of us and it hit the car many time till I turned the steering wheel to go away from there. Everything was very fast and confusing. I`m still trying to understand what happened with the car. The car was out of control and the car never tried to break or stop. I think it has stopped because I pressed the P button. I am so frightened and scared about what happened. My daughter and I, the passengers in the car in front of us and the people in the park could have been seriously injured. I opened a report at Tesla in the same day.

Wiper failure when set to automatic (rain-sensing) when vision system shut down due to poor visibility. A little background: I've been driving for 50+ years, about 1.5M total miles, most of it commuting. I'm a software engineer with 45+ years of experience, mostly in embedded systems. Problem drive: most settings, including headlights and wipers, on auto. Autopilot was on. Drove into a heavy rainstorm, auto wipers worked well, speeding up until they were on high. Traffic speed dropped from 70+ to less than 35 due to rain. Drove into a band of torrential rain. Saw a pop-up on the screen that said something like autopilot turning off due to diminished visibility. Autopilot (speed control) then turned off. THEN THE WIPERS SHUT OFF. Let's see, guy designing vision system: can't figure out anything from camera images, so let's warn user and shut off stuff that relies on the camera. Like autopilot. Wipers? Leave them in the last state? Nah, turn off the enable signal to the auto wiper state, too. Torrential downpour, almost no visibility, and my wipers just shut off. I frantically kept pressing the wiper button on the turn signal stalk to force a couple of swipes and force the wiper pop-up menu, then take my eyes off the road with possibly someone stopping right in front of me (yes, I slowed down) to do hand-eye coordination on the wiper pop-up to hit the manual setting full speed button!
