  1. Powerboost Cavitating Noise on Cold Start

    Update on mine. Since they've replaced the transmission a couple of weeks ago, the last few days has been the coldest. This morning was about -30C and I had the truck cold start, nose down, no noise anymore. I tried it the last two days as well where the temperature is about -20C. I hope this...
  2. Powerboost Cavitating Noise on Cold Start

    @Dannyboy80 That sucks. I just got the truck this morning. Here's the update. The comment from the service order "Remove and replace transmission as per WSM. Download transmission strategy to PCM using FDRS. Go for adaptive road test/ relearn. Fluids good. Repair complete." The cold snap just...
  3. Powerboost Cavitating Noise on Cold Start

    Yeah. The truck is in the shop for a week now. Waiting for it to be done. Hopefully, soon. So I can rest it out while the cold snap.
  4. Strange noise during cold start on Powerboost

    I exactly have the same problem. And up to now, Ford is still troubleshooting. I got mine May 2021, and it started the noise when it was colder about November 2021. After multiple times of trying to replicate it, the first job was to replace the flex plate and separator plate. Nope did not work...
  5. Powerboost Cavitating Noise on Cold Start

    Update: The noise is still there after the software upgrade (which Ford recommended on Dec. 12). So now they ordered transmission assembly. It will take a couple of weeks again.
  6. Service Advancetrac warning message

    Update: They did a software upgrade thus clearing the alarms. This happened to me before but with just a "service engine" lamp, SW upgrade then done.
  7. Service Advancetrac warning message

    Thank you! Yeah, I really hope it will clear soon. And not sit in the dealership. Got to drive with family somewhere for Christmas to New Year.
  8. Service Advancetrac warning message

    Yeah, I tried after 30min and it is still there. I will tomorrow morning again. Unfortunately, I do not have Forscan. Maybe I will take it to the dealership first thing in the morning and see if they can fit me in the day. I was reading some sites about it. Generally it tells me that I will...
  9. Service Advancetrac warning message

    Coming home tonight, really cold -27C (-16.6F). Backing up my driveway then this happened. Service AdvanceTrac is the main message. Additional messages are Hill Start Assist Not Available, Pre-Collission Asisst Not Available, Check System Brake, Reverse Brake Assist Not Available. Anybody...
  10. Powerboost Cavitating Noise on Cold Start

    Update on my Powerboost Noise: The dealership replaced the flex plate and separator plate. Because this is what they saw other dealerships were doing. Anyway 2 days after that fix, today cold start about 0C (32F), the noise still there. It's quiet because it is not extreme cold. This sunday will...
  11. Powerboost Cavitating Noise on Cold Start

    Update: I am still waiting for the parts to arrive. Also, today is cold. Of course the noise is still there. But I noticed something. The noise is still there then I started to shift to R or D. The moment that I shifted from P, the noise disappears. I wonder if the noise is not related to ICE...
  12. Powerboost Cavitating Noise on Cold Start

    They never did. After they saw the fix from other dealers they just did that.
  13. Powerboost Cavitating Noise on Cold Start

    Here's an update. Kinda good, I guess. The tech opened a hotline and found similar reports from other dealers. Hotline confirmed to replace Flex Plate and Separator Plate. I am not an expert, but if those are metal then it could contract during cold snaps. Maybe. Not even sure if there will be...
  14. Powerboost Cavitating Noise on Cold Start

    I just asked them. I'm waiting for them to let me know.
  15. Powerboost Cavitating Noise on Cold Start

    Update on mine. They tried to replicate this morning but they were not able to. I was not there, I should have gone. It was cold this morning, and it is parked nose down, not as much decline as my driveway though. Anyway, the dealer said they will open another ticket with Ford to get support. I...
  16. Powerboost Cavitating Noise on Cold Start

    Some update on mine. I will be leaving my truck tonight at the dealearship so they can replicate the cold start tomorrow morning. The forecast is cold tomorrow morning around -20C (-4F) so should be good to replicate it again. I’ve heard of the downslope parking at another forum. And I am parked...
  17. Powerboost Cavitating Noise on Cold Start

    How do you know if you have a "leaky" Heat Exchanger? Something actually leaks to the ground?
  18. Powerboost Cavitating Noise on Cold Start

    It does go away in about 10 minutes. Even if the HVAC is off it will start the ICE, the panel will show the reason is "Engine Cold".
  19. Powerboost Cavitating Noise on Cold Start

    ThanksI will check the reservoirs later. I’m sure it is good, but I’ll check.
  20. Powerboost Cavitating Noise on Cold Start

    I love the rest of the truck especially the generator when we go camping. I pull a small RPOD. It is able to run the AC on hot days if we camp unserviced. I am really hoping this year that they look into it.
