There have been many TSB's for this issue. None have fixed my 2019 Titanium. 30k miles. https://www.fordedgeforum.com/topic/26728-2019-edge-low-speed-surgebuck/

Could you keep us updated on whether the described repairs fixed the issue? My 2019 Edge is still having slow speed buck/surges after 4-1/2 years. Numerous TSB's and PCM resets have done nothing. Worst vehicle I have ever owned.

Breez, Can you explain the connection between the EGR valve and the bucking/surging issue we are having? Is this actually an engine problem and not transmission? Customer support is worthless and I (we) have no direct access to Ford technicial engineering. Just odd to me that no one who has read or posted here are Ford repair techs or a Ford employee. Whether Ford acknowledges it or not there is something wrong with our vehicles. I've lost count on how many TSB's I've had done and resetting the PCM. It's not fixing the problem. I'm also frustrated with dealership service departments that state there are no codes or could not duplicate the problem.

Thanks. Mine will bounce at each shift. As rpm increases and the tach/engine reaches the shift point, the rpm will drop, then increases about 300 rpm, then settles back down. Does it all the time at each shift.

Icy, Looked at your video. Did you see the tach bounce at each shift or at a steady speed? I asked my dealer service to looked at that specific issue. They claimed they could not duplicate issue. How did you get your service department to diagnosis the torque converter?

Same here. 28k miles. No change. Problem persists. I'm on the phone with customer service. Same response as always. "CS can't provide any technical support. Need to take the vehicle to the dealership service department." Asked to speak to a supervisor. Was transferred to a survey. After answering the questions, phone disconnected.

Anyone know if there is a reason why I have two, what look to be, drill holes in the muffler? Just noticed them today. Saw a black streak along the muffler's bottom. Started the vehicle and felt a small air flow. On closer inspection I noticed two holes.

Lazy Ford engineering and poor quality control. My 2000 Explorer had a three speed fan for rear seating. Never had a cooling problem.

Had a thought as to why are vehicle issue has not been resolved. Last time I picked up my Edge the technician mentioned he does not get paid unless the vehicle is fixed. Didn't think much about that statement since we were still discussing the vehicle's problems. Is that a correct statement or maybe varies with dealership? If true, the techs know Ford is not providing a valid fix so they don't spend any time diagnosing the problem or attempting a fix. Ford hasn't provided one. Why waste time on a job that will not be fixed and see no payment for the time spent.

Same with mine but at slower speed, 15 -20 mph. I took my 2019 Edge in again. Dealership had the vehicle for a month. Was told TSB 21-2389 was done. I never asked for a ticket so I don't know if that is true. Still have the issue. Also asked to check the bouncing tach at each shift and the sensitive throttle pedal. Still have both of those issues.

I noticed that you said the dealership reset your PCM, does that mean they simply cleared the shift adapts or did they actually reprogram the PCM to the most current version? I have no idea what they claim they did to the vehicle. I'm just quoting what is written on the service ticket. Whatever was done, does not and has not corrected the problem. I don't usually go by what a dealership says because I have come across far too many situations where a dealership says there is not an issue and yet there is a tsb that addresses the problem word for word or they just "reset" or clear the PCM memory. As far as the tsb being updated to include new model years, that happens all the time because software glitches can occur regardless of how up to date the software is. Yes, true, but that's not how the TSB description was written. What difference does "new model" make if the new Edge is still using the 2019 version transmission? I know it affects the 8F35 transmission, period, no matter what year vehicle it's in so why mention "Carry over to new model". The new TSB is because the problem is still not fixed. And in my situation, three full years and one month. Vehicle is still sitting at the service department for now eight business days and has not been looked at yet. Personal computers and phones have updates all the time. Another example is the ZF nine speed that Honda has used since 2015. Just last year Honda released another software update for MDX and TLX models spanning from 2015 to 2020 that had to do with hard shifting. Regards, Jason

Interesting update. Another TSB. I took my Edge in again for service Wednesday Jan 7th. Gave the service manager a copy of the issues and the letter from Customer Care. Buck and jerk was the main issue. I also asked to check why the tach bounces on each shift and the sensitive accelerator. On Friday I received a call stating the tech believed it could be a torque converter problem. Waiting to hear from Ford. I also received a call from Customer Care. Stated the same. Curious why the TSB wasn't mentioned since it's dated 4 November 2021. Not that I trust the TSB to correct the problem. We've all been down that road many times before. Will update once I know more. Just re-read the TSB. "This bulletin supersedes 21-2081. Reason for update. Concern Carrover to New Model". Not, we didn't fix the problem with all the other TSB's or replace the poorly designed transmission. It's only because the new model owners are now complaining.

I haven't. If you decide to give it a try please let us know the outcome.

I believe it's a badly designed transmission. Don't believe Ford has any plans to replace the ones that are defective. If it was simply a software problem, why all the TSB's that have done nothing.

Great suggestion. Have a copy ready.

That's not good news. I have service scheduled for Jan 2022. Should I even bother. Several months ago I sent another series of letters to Ford management. A week ago I received a letter from "Marguita" Customer Service Representative. Recommended I schedule service "for a more up-to-date diagnosis to determine the cause of any symptoms........." I guess I'll give Ford one more try a identifing the problem and fixing it. Thought I'd ask this again. Does anyone else experience a very sensitive throttle response? With the vehicle idling, if I slightly touch the accelator with my foot the engine revs to 2000 rpm. I can't do slight increases in rpm. It's either idle or 2000. If I try to release pressure on the accelator the rpm goes back to idle. Is there an adjustment in the computer that controls throttle sensitivity?

Curious if anyone reading this thread is an actual Ford certified tech. Do you have any information you can share regarding this issue? Is Ford aware/acknowledged there is a problem? Is Ford actually doing anything constructive to resolve it? Published TSB's haven't worked.

Hey Breez, Please keep us informed to the outcome. I'm also planning another service visit. I mailed yet another letter to Ford the first of September. So far silence. I guess electric F- trucks are of more importance.

Nope. I've been dealing with the problem for going on three years. Will probably schedule another service visit.

Haven't heard a knocking noise other than when auto engine shut off restarts the engine when releasing the brake. It annoys me so I turn it off everytime I start the vehicle. You could have the TSB performed and see if the helps. Nothing Ford nas done so far has fixed the problem.

Me too. In Janurary 2019 I traded a 2000 Explorer XLT with 275,000 miles for the 2019 Edge Titanium. Explorer ran perfectly. And what do I receive for my vehicle loyalty to Ford?

If not the transmission, any idea what it could be? Ford could use the help. I asked this in the above post. Can you check to see if your vehicle has difficulty keeping a steady rpm. Place transmission in neutral, set parking brake, then try to raise rpm to 2000 from idle. I suspect it could be a sensitive throttle sensor. Why I asked about holding the rpm at 2000. I experience it too. The hesitation is either idle rpm or 2000+ which may cause the transmission to not know what gear to be in. Slightly remove your foot off the pedal and engine goes back to idle causing a downshift. Touch the pedal again and now engine is back to 2000+ and upshift. Someone also mentioned in a post they did not have the problem if using cruise control at a slow speed. I don't recall if you can set cruise at 15-20 mph. If the pedal sensor is the problem that could explain why we feel and see the bucking using the pedal but not when using cruise control. Also, please consider a letter to Ford.

A resolution from Ford, No. I'm almost at three years dealing with this issue and Ford. Please consider mailing a letter to Ford management explaining your issue and lack of a fix. Here's the address: Ford Motor Company 1 American Rd. Dearborn, MI 48126 Attention: William Clay Ford Jr., Executive Chairman James D. Farley, Jr. Chief Executive Officer Dave Filipe, Vice President, Vehicle Hardware Modules Elena Ford, Chief Customer Experience Officer If I could ask, can you check to see if your vehicle has difficulty keeping a steady rpm. Place transmission in neutral, set parking brake, then try to raise rpm to 2000 from idle. I can not. I found this problem when having the engine oil changed. Tech asked me to raise the rpm up to 2000. Couldn't do it. Either idle or near 3000.

DGW, Thanks for posting your vehicle's issues. While I too deal with the problem daily, I am concerned about what could be happening long term. What happens a month after the warranty expires and we have massive drive train failure. Do you think Ford will cover it? What ever anyone thinks, and in my opinion, the bucking/surging is not "normal" to any transmission. If it was, wouldn't all vehicles do it? No, it's lazy engineering and Ford management's lack of concern. All I know is, if you ever go to sell the vehicle do it when the engine and transmission have warmed to operating temperature.
