NISSAN ALTIMA RANDOMLY WON'T ACCELERATE ABOVE 25MPH!!

In today's video we take a look at a2015 Nissan Altima w/ a 4 cyl 2.5l engine. The customer complaint is that the accelerator pedal will randomly stop working while driving and the vehicle will not go over 20mph! The owner has already replaced the throttle body and the accelerator pedal sensor assembly. There are no codes or DTCs stored in the computer, so we have to figure this one out the hard way! We catch a break when we realize the brake lights are intermittently getting stuck on! Follow along as I walk you step by step through my troubleshooting and diagnostic procedure. I hope this video helps someone! Refer to Technical service bulletin NTB15-111 for more information!

The biggest take away for me, is the fact you genuinely seam to care. That shop and customer are extremely fortunate they had such a great resource to turn to. How many people would be getting ripped off or replacing a perfectly good car over a relay.

[@gonzalo_v503]

Just replaced these on my wife's car 2014 sentra. Hers was running fine but while driving it would lag and her rpm would go down. You'd press accelerator all the way in and nothing. When turning on the car too, the pedal icon wasn't on and you could start the car without pressing the break. Bow after the new parts, it works!!! MAF could also be a symptoms, I cleaned it prior to doing the brake sensors

[@user-gs1il7xl8d]

Excellent, fully informed video including how you interpreted the diagnostic information. I’m a little surprised that the diagnostic tool didn’t alert you to the braking issue. Fabulous that you happened to notice the brake lights as you walked past the rear of the car and analytically connect it to the initial complaint! You are truly a mechanical detective!! Looking forward to more revelations!!!

[@stevec5657]

It's cool when you post these head scratching diagnostic videos. Awesome job!

I just encountered this problem (limited acceleration, trac control light turns on) on a 2021 Hyundai Accent, but I received a P0121 code (throttle body). Found out it was replaced at the dealer, but code and symptoms returned. Just for your video, I’ll ask the dealer to check the brake switch and relay now. Thanks for your great videos. You’re a great teacher!

[@tonylin9833]

Thanks for the great video. I met the same randomly driving issue just after replacing the brake servo. It was a 2016 Nissan Tiida 1.8L with CVT transmission. I used ThinkTool to record data like the first time you did. I cleaned the MAF, which seemed better, but still having the issue. Finally someone noticed the brake lights on and then I redid the adjustment a little bit longer. The issue was gone!!!

I'm in a mechanic master or technician BUT I've been search stuff on good search and KZbin video on how to troubleshoot in fixing Toyota Camry and Corolla that auto repair shops have no idea what I'm talking about.

Thank you so much for this video; it saved me from spending a lot on parts to find the problem. I had the same exact issue with my 2018 Honda CRV Touring. I drove two hours away from the city for work, and my car would randomly slow down numerous times. The RPM would drop, and the car slowed down as if the brakes were being applied. Then the RPM would go back up, and I'd regain speed, all without any check engine light or warning signs. Upon returning to the city, I had it checked and scanned, but no fault codes were found. They inspected the throttle body and cleaned it, checked the plugs (which were fine), and examined the fuel pump (which they also cleaned). They even removed the differential, but the problem persisted. The only option left seemed to be buying a new throttle body. However, I came across your video after extensive research before making a decision to purchase the new throttle body. To confirm that the issue was related to the brake switch, I turned on the cruise control to see if it would turn off on its own without touching the brake. It did indeed turned off, confirming that my car was applying the brakes randomly. I replaced the brake switch, and the problem was solved. My car now runs like new again. Thank you! 😊

yes it's exactly what it does you can even confirm it in a perfectly working car, press the brake and then try to accelerate it will be unresponsive

[@markrup6369]

I'm amazed that the two brake switches having the same status doesn't throw a code.

[@russellhltn1396]

I was surprised at that as well. But then I saw it was two separate switches, so it probably happens normally if the pedal is in just the right spot. I think most other cars have a single assembly with the two switches so they are less likely to do that.

[@michaelshadwick3487]

I think your video just saved me thousands of dollars and many hours. I have a 2013 Nissan Maxima. I’ve been having a very similar issue issue but not stuck at 25mph my car will basically buck through acceleration randomly but I can get up to speed 50-60 if need be. Totally intermittent it took a long time to get worse and is very concerning when driving. No codes. Had the car looked at by 2 mechanics on was Nissan. Replaced the spark plugs for routine maintenance and did tranny fluid not to long ago. Nissan told me replace the transmission which is a awful answer. My engine mount is also bad so we thought maybe the engine moving caused something to be loose or crack letting air in. So we check d all tubing and wires to see if anything looked bad, we tested the car a whole bunch shaking it and braking quick hard Corning and realized something felt like it was sticking, and causing the brakes to go off. No Abs warning but we thought maybe that was kicking in for some reason. Watched your video and it all clicked together. It’s bucking on acceleration after hitting the brakes… the brake switch is sticking… my father was driving behind me and saw the brakes flicker a few times meaning it was engaging when I wasn’t hitting it. I just switched the plugs for $100 and no issues so far. Thank you so very much

I only go to a mechanic "IF" I can not find the problem after first going through basics. Complete and thorough research. Going through every avenue and even then if I talk to a mechanic I look at his face, body language, listen to his replies evaluate his conclusions, compare them to my research. I have only had one mechanical problem that I couldn't figure out and guess what? Not even the mechanics could figure it out. Replaced brakes (all) to include wheel cylinder(s) calipers both front, Master cylinder, ABS module. Yet, seemed as if there was air in the system. That's another story.

Yes bravo for the Automotive detective work that Nissan Engineered! Kudos to you my friend. I have subscribed and I'm only borrowing my friends 2018 Nissan Versa bc someone decided to vandalize my Mitsubishi Outlander. This Versa has been in the back yard for over a year parked. My friend doesn't know ish about cars. First thing I had to do was put a new battery in it. I then was able to scan it for codes. 2 codes popped up P0603 and P062F. However the symptoms while driving are exactly what is described in those video. This POS JATCO CVT tranny is whining, the RPM's are at idle while pushing the accelerator pedal. No throttle response. If you let up off the pedal the transmission the car is moving based on the idle speed being at about 1500 RPM's . To think a Brake Switch can wreak this much havoc is insane and Nissan INC needs to pony up and recall all these models that needs these brake switches and relays replaced. Its bad enough the transmissions are shotty crap that barely meets government standards now there's this issue that seems to be common place with hundreds of thousands Nissan car owners. Where's the NHTSA with this issue and when is this issue going to be rectified??? There's enough Nissan car owners Altima , Versa,Note,Sentra,Maxima, Rogue to get Nissan to recall these models and EAT THE COST of these repairs!! This is a DANGEROUS problem that people are suffering with that SCREAMS MALICIOUS on Nissan's behalf! There's power in numbers and I say let the Recall campaign begin!!! Enough is Enough! How many people have been told they need to replace their transmission when the main culprit is this Brake Relay and Switches!? How many Nissan owners are going to get seriously hurt or killed because they're driving around with this problem. THERE ARE OPTIONS. NISSAN INC address these issues or we can find a few attorneys who take on automakers who fail their customers!
