Engine control unit failure

- Crystal Springs, MS, USA

I left for work, acceleration at slow speed around 30 mph within 40 seconds, the car began to gain speed, I let off the gas pedal, still accelerated. I tried slowly using brakes to slow down - no response. At this point, I notice that cruise control light, was lit up, on the dashboard but not set. I'm now gaining speed of 72 MPH. Not even 1 mile, from turn off. I literally fish tailed three times, then the car slowed down and I ended up sideways, in a ditch. Chipped hubcap and some plastic piece hanging, from underneath the car. I had a bystander, whom was headed towards me - stop in fear of what happened. Got the car out of ditch. I parked, checked for leaks, nothing. Since this incident, I'm in fear of this happening again. I'm assumption was the accelerator stuck. No brakes is dangerous, let alone feeling like my life was gonna end. I cried. Thinking Jesus my children were home. I have noticed that both airbag "warning" signs have displayed and won't go off. I would hate to have or hear of a fatality, from this. Please look into other reports. I felt like I couldn't even explain this bizarre, unlikely/impossible event to happen but it did.

I own a 2017 Nissan Altima. This vehicle has been having similar issues that other owners have reported with the vehicle failing to accelerate after stopping or sitting ideal while running the and you go too take off, barely moves to a crawl even if the gas pedal is to the floor. It will also loose power (speed) without warning while driving. The vehicle will not register any warning lights when this occurs not even a check engine light comes on when this occurs. It does not register any issues in a diagnostic test to which one was completed by a Nissan dealer in Lebanon Pa. (Moyer Nissan). Because of this the Service advisor/mechanic indicated that they would be "guessing" as to what the issue was even though it is clearly a issue with the 2017 models; it hasn't been the first time I'm sure that someone came to that Nissan dealer with the same problems and knowing that the 2017 have complaints with CVT Transmission. I'm no mechanic but I think it is a blatant disregard for human life if that they do NOT recall this vehicle or at the very least replace all equipment (transmission; throttle, pertaining to the accelerator) at no expense to the owner.

Transmission: this is the 2nd transmission in about 22,000 miles. Car will start to stall out and then high rev the rpm-??s. This has caused significant power loss suddenly in traffic. Issue has been recreated by mechanic and has been inspected thoroughly. Previously transmission was rebuilt with the torque converter being replaced. No indicator lights have come on prior or during sudden loss, only check engine light once. Shutting off vehicle for approximately 5 or so minutes resolves the issue but only for a limited amount of time.

When driving my Nissan I had stop at light/ stop sign.My car notify me with a check engine light. It wouldn't accelerate in a matter of seconds I was able to continue driving. I notice it happens every time I have to stop at lights and or stop signs frequently. It first started at about 85,000 miles. I bought it at 65,000 miles I still owe for the car I took it to Nissan and they told me that it no longer had a warranty for the transmission. It has alittle over 100,000 just think that if there's alot of consumers complaining about the same issue it needs to be investigated and stop selling it until the issue is corrected.. In my opinion..

Was driving and came to a stop. Went to accelerate and car stuttered and acted like it didn-??t want to accelerate. This is not the first time, but it was about a month ago when it last did it and almost caused me to wreck. Car is only at 99k miles.

I was driving my 2017 Nissan Altima SV, today on 3/3/23, and had just got on to a busy highway. I had my foot on the gas pedal trying to get to 60 mph. However, the car wouldn't accelerate past 40mph and was making a humming noise, even as I floored it. I looked to see if the car was in another gear but it was in drive. I had to pull the to slow lane and try to find a place to turn off. I came to an intersection where I had to stop, and again, couldn't accelerate to the 60mph that other traffic was traveling. It would only go about 40mph. People were changing lanes to pass me in busy Friday afternoon traffic. I finally found a shopping center to stop as I didn't want to get on the freeway to get home. I stopped the car but ended up eventually getting on the freeway and didn't have the problem again for the 15 miles. No check engine light came on at all during the acceleration problems. I have been researching the problem and the car may have gone into limp mode. I am taking the car to the shop tomorrow. I don't drive the car a lot, and it doesn't have a lot of miles on it, so I'm very surprised and terrified now to drive the car. I've been reading people with Altimas saying they have had a hard time getting a diagnosis for this problem because it doesn't occur sometimes at the shop. It's distressing to think this problem may come and go and I could be in 70mph traffic on a busy freeway, which I often am. I have not been in an accident, so no inspections until tomorrow when I go to the mechanic. This if the first time this has happened and I had no indication there could be a problem. I have barely been driving my car for the past two years as I have been working remotely. I bought Nissan 100% because it had a good reputation, but now I'm reading about this weird and potentially deadly problem.

After stopping at red light, Vehicle could not go more than 10mph. Stop the vehicle, turn off and restarted, now Vehicle could not go further or reverse. Luckly, at the intersection, i did not get into accident. My Altima is at 65000 miles. Nissan Altima CVT had an issue and need to recall for this fix. I saw Nissan did recall up to 2016 Altima, some reason, they did not include 2017 Altima. Please take a look into 2017 Altima data from Repair and Dealers shop to find out how much consumers are paying out and got into safety issue.

The contact owns a 2017 Nissan Altima. The contact stated while driving on the highway, the vehicle inadvertently accelerated and then independently decelerated. The contact stated that he was able to drive the vehicle back to the residence. The contact then stated that after he turned off and restarted the vehicle, the check engine warning light illuminated, and the gear shifter failed to engage. The vehicle was not diagnosed. The vehicle was not repaired. The dealer was not notified of the failure. The manufacturer was notified of the failure and informed the contact that the vehicle was out of warranty. A case was opened. The failure mileage was approximately 118,000.

Delays in acceleration. When operating the vehicle. At a complete stop. When I depress the gas pedal there is a few seconds delay before the vehicle starts to accelerate. No warnings appear on dashboard. No check engine light, no visible indication of problem.

Passenger seat belts does lock all the time. Front brakes I've had issues with since day one. Dealer tells me on 3 occasions there fine nothing wrong but have gone thur 5 brake pads sets. Now when I step on brakes or give gad to go it's like the throttle cable or something isn't working because it won't go. Have to either give it afew than try paddle or put in N than back to drive. Happens alot in traffic.

- Newport, TN, USA

This incident happened many times on the highway and normal streets, when I stepped on the pedal for gas not responding, and I needed to wait almost 40 seconds, and looked like I had lost power, like the transmission not working correctly

Twice in one day, one hour apart, the xar would not accelerate, then accelrated wildly. First time, pulling onto a road from a stop, it hardly sped up, I put the pedal to the floor, and it did not increase speed as expected, in fact hardly at all. I was trying to merge with oncoming traffic so this would have caused a wreck if there wasn't as much space between me and the oncoming traffic. I kept trying to accelerate, pushing the pedal, letting it out, pushing it again, and it continued to not accelerate as expected. I then pulled off the road to let traffic pass and see if it revved in park, and it sounded fine. After traffic cleared, I tried again, and thia ti.e it functioned normally. I drove about 50 miles, stopped somewhere, and ha no problems. When I left that place, trying to pull onto the road and merge with oncoming traffic, it happened again. I once again tried to push the pedal further to speed up, and at first it would not, but then it SUDDENLY accelerated and I fishtailed in a busy road. Luckily there was not an accident. I let off the pedal and gained control, and it drove normally after that.

The car delays to accelerate from a stopped position. While sitting at traffic lights you can press the gas all the way to the floor and the car will not accelerate for a few seconds and then slingshot you forward. After this happens the car will not change gears and revs to 5000 RPMs while in the middle of traffic. If you can safely pull off to the side of the road and turn the car off for a few seconds and restart it, the car resumes to function normally. This is extremely dangerous, especially when making left hand turns with children in the car. In my research, this a known problem to Nissan and there has been no recall.

I am driving for about 40min my nissan stop accelerating. I can floor the gas pedal. It will not increase speed. My speed starts to decline. I can't go faster. I have to put my hazard lights on and coast to get of freeway. No check engine lights no warning. I have taken it to nissan to get updated soft ware. Still no warnings no codes. I paid 150 for them to tell me nothings is wrong. Clearly something is wrong.

Delayed acceleration my 2017 Altima is experiencing a delay when accelerating from a stop. It won't rev or do anything for a couple of seconds no matter how far down the pedal is. Then all of a sudden it'll go. There is no check engine light and no codes. If I turn the car off, it's like it resets and has more power afterwards.

I have a 2017 Nissan Altima sv, 4cyl, 2.5L... I am having worsening problems with acceleration. When attempting to pull off from a red light for example, it will hesitate for about 4,5 seconds, rpms increase then a surge of acceleration. Also, while driving it will lose speed with my foot on the gas, even with the rpms up as if it were moving faster.. thankfully the drivers behind me were attentive or it could have caused me and others a great deal of damage, like when I was trying to accelerate from a cross street turn lane. It was sporadic at first; I went to valvoline and got replacement transmission fluid, and the guy turned off the engine light. It started up again a few weeks later, and I got a new air filter and went back for a fuel system cleaning. Another guy reset the engine light again, and now(about 3 weeks later)it's back with the same problem. Sometimes, I'd pull over and turn off the car and it helped a bit. Now(yesterday) that isn't helping and the slow acceleration and speed happens every time. I used the diagnosing tool at auto zone which read, "P0776-pressure control solenoid B performance or stuck off". I am seeing that there are many complaints about the exact same thing, and even a recall on the models up to 2016 regarding this, but 2017 and after seem to be getting ignored.

There is a delay in acceleration from a complete stop. Stops for red lights, stop signs and turns are extremely dangerous as the issue of delayed acceleration occurs randomly and without warning.

- San Antonio, TX, USA

The vehicle shuts off while driving, does not maintain a solid speed, increases and decreases speed on it own, when stopped the vehicle with not go when the gas pedal is pressed, it will take a few moments and then accelerate at a really high speed or force. The windows randomly stop working, the lights flicker on and off, the steering column tightens and the vehicle randomly shuts off while driving it on the road. It will display that the key is missing and turn off. It has taken several minutes to restart the car. This happens during idle and in motion, on the highway or in the city.

My 2017 Altima had been jerking, almost felt like the transmission was slipping. This would occur at random acceleration causing the vehicle to stall for brief seconds before it would actually accelerate. On top of that vehicle has now started a loud wining sound that gets louder when trying to accelerate. The car will not move for several seconds and then gradually it will begin to take off. This happens at every stop or slow down made. My cruise control no longer works either. Several times in the past I had issues with the vehicle not wanting to shift out of first gear. Since then this is what has occured. At this point I can no longer drive the vehicle due to no acceleration and im afraid that I might cause an accident due to extremely slow if not any take off from any stop. I am very upset over this issue considering everything I have read up on all leads back to the cvt transmission problems from several other owners, and the fact that several recalls have been made due to this, but for some reason not the 2017 Altima? it is apparent to me that this year has also been affected. I am a single mother and can't afford another exspince at this time especially since I lost my job due to covid-19. Now I am unemployed and cant drive my car due to transmission problems that obviously seems to be a reaccuring problem for Nissan with the cvt transmissions.
