2012 Nissan Altima

I am reporting a potential unintended automatic emergency braking event involving a 2025 Tesla Cybertruck. On 23Mar2026, at approximately 40 mph, I was traveling behind a Tesla Cybertruck on a public roadway. There were no visible obstacles, hazards, or debris in the roadway that I observed. The Cybertruck suddenly and aggressively braked without warning. The abrupt deceleration appeared inconsistent with road conditions and is consistent with what is commonly described as “phantom braking.” As a result of the sudden stop, I was unable to avoid a collision with the rear of the vehicle despite maintaining a reasonable following distance. After the impact, the Cybertruck initially left the scene, stating they were unaware a collision had occurred. No debris or roadway hazard was documented at the scene in the police report (FVPD report #2026-00777). The other driver later indicated a plastic bag may have triggered the vehicle’s emergency braking system. I am submitting this report as a potential safety issue involving unintended or inappropriate automatic emergency braking behavior.

I drove out of town about 40 miles and everything was fine, next day went to leave to come home and immediately noticed high RPMs going about 20MPH. I pulled over, turned the car off and turned it back on, started driving and same thing. I had no choice but to drive it on the interstate. I could get up to 60 very carefully but I was still sitting around 4000rpms. It wouldn’t shift gears at all (I know it’s a CVT and doesn’t have gears). I then noticed a high squealing noise, thankfully made it home with a lot of honking and middle fingers even though I had my hazards on. Once I made it home, plugged in my OBD scanner and had a pending DTC of P1778 which I have found to be the stepper motor. Aka the death code. It’ll start, shift into all other gears, but is making a high squealing noise even when idle and in park and when revving in park the squeal gets louder. I even attempted the “semi manual’ to see if I could get it to catch, I couldn’t at all. No matter what “gear” I was in it wouldn’t bring the RPMs down.

The vehicle is unsafe to driver and others on the road. The power steering hose has had a leak since it was manufactured and was not fixed by the manufacturer at all! Tie rods gave away within 5 years of a mileage less than 24,200 miles. Cv joints along with tie rods have been easily compromised and damaged causing loss of control and steering .suspensions are no longer in tact nor reliable and will pose a danger. All errors were not found by manufacturer and has caused immediate danger to not only driver but everyone on the road. The engine has a rattle only after 2 years which is not usual.

Clunking and bouncing from right tire followed by acceleration not working properly

The sensor was replaced but the light engine light still came back on now the speed sensor is causing the issue. The abs light comes on while accelerating it jumps and jerks

The contact owns a 2012 Nissan Altima. The contact stated while driving 40 MPH, there was an abnormal banging sound coming from the rear end of the vehicle, followed by a dragging sound. The contact also stated that the vehicle began to shake abnormally. There was no warning light illuminated. The contact pulled over and discovered that the rear driver side tire was hanging from the suspension. Due to the failure, the vehicle was towed to an independent mechanic where it remained. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 236,000.

The transmissions go out fast in the ctv Nissan Altima 2012

I have owned this vehicle for over ten years and now there is paint delamination on the hood and roof of the vehicle which is a manufacture defect.

Service Engine Soon light on. Was driving on highway at 55mph Transmission started to slip and car started to slow down while I was pressing gas pedal. The more I pressed on gas pedal the more the car lost acceleration. Had to move off to side of the road and turn car off. Took to mechanic and had transmission flushed and plate replaced. Transmission needs to be replaced. Ran diagnostic and codes for Transmission comes up.

I have a 2012 nissan altima that I purchased in 2018. in florida. check engine light appeared first. it currently doesn't run because of the transmission. it doesnt excelerate above 20mph. is there is a nationwide recall because of the cvt transmissions going bad?. I already tried to fix 2 separate parts on the transmission the code I'm getting is p1778. I changed the stepper motor and valve body and it's still won't go above 20mph. I don't have 5,000 to replace a transmission. we've been stuck on the road twice in traffic when it doesn't want to excelerate above 20mph

Driving back from Wichita today my hood kept popping open. I had to pull off the interstate and close it.

I just recently financed my car I haven’t even had it 1 month and every time I drive it for more than 1 hour the transmission fills like it’s going out on me on the freeway I can’t seem to get it to go over 40 miles an hour and it makes sun weird noise and idles high I can also feel it when I drive I can fill it slipping it jerks it only has 117000 miles on it I did mention it to the dealership and he said it wasn’t the transmission it was something else I know it’s the transmission I just wanted to know if it was a recall or anyone else had this issue I have not had it inspected being it hasn’t even been a month yet

The contact owns a 2012 Nissan Altima. The contact stated while driving at an undisclosed speed, the traction control warning light illuminated, and the vehicle was jerking. Additionally, the vehicle failed to accelerate above 25-30 MPH. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 180,000.

When I BARELY accelerate my car it does a very aggressive bucking motion along with loud noise. I have done put over $3k in vehicle! Nissan fix your shit!

What component or system failed or malfunction and is it available for inspection upon request. The CVT failsafe high fluid temperature protection mode enacted while I was driving on the highway at speeds of 65 to 70 mph going with the flow of traffic it is not available for inspection upon request because this issue only occurs while you're driving down the highway. How was your safety or the safety of others put at risk? My safety and the safety of my passengers and the safety of my fellow commuters was put in jeopardy due to negligence of the manufacturer of the 2012 Nissan Altima when this occurs all acceleration ceases your foot can be all the way to the floor on the gas pedal and your car will not accelerate and in the fast lane on the highway when this happened I became a Sitting Duck in the flow of traffic cars are flying by me and my passengers and I can't get enough speed to change lanes and get out of danger due to a failsafe that Nissan put in these cars on purpose they were fully aware of these issues this is a direct quote from the 2012 Nissan Altima owners manual page 5-17 warning when the high fluid temperature protection mode or fail safe operation occurs vehicle speed may be gradually reduced the reduced speed may be lower than traffic which could increase the chance of a collision be especially careful when driving if necessary pull to the side of the road to a safe place and allow the transmission to return to normal operation or have it reparative necessary. Has the problem been reproduced or confirmed by a dealer or independent service center. Unknown. has the vehicle or component been inspected by the manufacturer police Insurance Representatives or others. Unknown. Where there any warning lamps messages or other symptoms of the problem prior to the failure and when did they first appear. Zero warning lamps no messages just all of the sudden no acceleration and I am in a very dangerous situation which could have cost many people their lives

Hi I’m having trouble with my transmission in my car due to a safety feature that Nissan has installed on there cvt transmissions. After driving for 1 1/2 to 2 hour trips my car does not accelerate or will have a slow time gaining speed. Nissan has a high fluid temperature protection mode that basically when the transmission temp gets too high the computer cuts you off completely and intentionally stops you from going any faster. This is a serious issues if your in traffic or driving somewhere on the highway and not able to move to the side of the roadway or to a median. If my car was to completely stop in the middle of the road due to this safety feature, it could cause collisions and life threatening injuries.

The airbag warning light started flashing in late November or early December 2022. I took the car to my mechanic on Dec. 5, 2022 who ran a diagnostic which identified the need to replace the sensor in the front passenger seat. The sensor is so integrated into the seat that the entire seat (not the back) must be replaced. I was then told that Nissan has stopped making the seat because the car is over 10 years old and a replacement is unavailable nationwide and will not become available. I called a Nissan dealer to confirm that the part is unavailable and they confirmed it. As a result, it is unsafe for a person to sit in the passenger seat. It seems wrong that Nissan can stop making such an essential part and devalue someone's life or the vehicle itself in this way. It also seems to me that I cannot sell the car in this condition and it only has about 76,000 miles on it. The vehicle is available for inspection should someone wish to do so.
