Found this article on Ford Ranger bucking/surging. Details on replacing DPFE sensor. https://www.ranger5g.com/forum/threads/egr-dpfe-sensor-assembly-replacement-write-up-lb5z-9j433-b.29247/ Appears Ford engineered this issue into other models too.

No I haven't. I am considering trying it if dealership refuses to under warranty. I'm always told it's "normal operation". I would like to know if there are any reprogramming requirements or is it just a remove and replace of components?

Are the EGR and DPFE sensors easily replaced or does it require the dealership?

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.
