Rumbling vibration in the front end when driving in temps below 30 degrees F. Appears to start and stop intermittently. Searching F150 owner forums reveals numerous other owners experiencing the same issue.

The truck has a grinding noise in the front end that goes way after switching it into 4WD and then back to 2WD. The is also a smell of metal heating up. I took it to a Ford dealer to have it fixed. The dealer said it was a bad IWE and parts were on backorder. Once they came in I took the truck back to the dealer to have it repaired and they advised me that Ford had put a halt on them repairing the IWE.

The issue occurs any time when the temperature is approx 32 degrees F or below. After starting up the vehicle and driving for 2 miles a loud grinding/rumble sound occurs and last from 10-120 seconds. The sound eventually goes away on its own but it sounds as if there are parts rubbing or grinding together. The noise is below the drivers seat. I've taken it to the dealer after the first episode however the temperature was not under 32F when they inspected the vehicle. There are no warnings when this sound occurs and to date this has not been a safety issue but it has only occurred 6-7 times since I've owned the vehicle(have not had many days that I've drove it when temperature below 32F) and I worried if this continues there will be a failure.

Problem affecting my 2023 f-150 along with many other owners who have 4wd and are in cold climates. See [XXX] for more. This pertains to the Electronic integrated wheel end (EIWE). In cold weather, vehicle begins to actuate the EIWE causing a grinding writhing the hub of the F-150. This grinding takes place while driving in 2H, or can be replicated by shifting from 4H back to 2H. The truck will then make the grinding noise for about 15 to 30 seconds. Ford has no fix at this time but a recall must take place to fix this faulty system! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The front transfer case or wheel ends will grind causing vibration and an audible growl when the outside temperature is below 32 degrees and driven first thing in the morning before the internal components have had a chance to come up to normal operating temperature. I suspect the hubs are either not fully engaging or disengaging and thus causing the grinding. This happens regularly in the AM and will last for 30sec to 2 minutes unless you press the 4 wheel high button. This is a saftey concern due to the fact that components are being prematurely worn and at risk of sudden failure resulting in the inability of operation. No error codes or warning lights.

Whenever temperatures are below freezing, the TCCM engages the front IWE system and hubs to warm up for the first 2 miles of driving. However, when the system disengages, the hubs are not fully disengaging from the IWE shaft and a loud grinding noise happens. I have taken my vehicle to the Ford dealer and they gave a contradictory answer by saying that it was a -??issue, -?? but that it was -??operating normally.-?? It is definitely not normal and they know it is a defective system that is damaging the drive system on a brand new vehicle with less than 800 miles on it.

while driving in gears between 8-10 I experienced a loss of power (Possible mis-firing) while at speed between 50-60 miles per hour. This occurs every time the vehicle is driven.

Loud vibration while driving, similar to passing over a rumble strip, believed to originate from IWES operating in colder weather. Fear of damage from grinding parts effecting operation of 4WD system.

Truck will randomly start making rumble strip or like you have knobby tires noise from front end. You can put it in 4 high and back 2wd an it goes away.this has happened at different speed and differs temp.

Loud humming noise coming from the driver side front end. It comes on randomly when temps are below freezing. It is something near the wheel such, likely the IWE as it grows higher pitch at higher speeds and lower at lower at lower speeds. When you hit the button to go from 2H to 4H or switching to 4 wheel drive, the humming goes away. Switching back to 2 wheel drive and it comes back sometimes. I see a lot of posts online with others having the same similar issue. This is on a 2023 xlt f150 with the 2.7 liter ecoboost. I contacted the dealer and they are aware of the issue but have not heard of any solutions from Ford. It does not appear to be a formal recall issue yet, but my guess is that it is something that should be recalled. This noise is fairly loud, I can send a recording of it. It also makes the steering wheel shake a little bit with it happening, fairly minor, but obviously not good. Sounds like they need a redesign on the electronic IWE.

EIWE (Electronic Integrated Wheel End) failure or malfunction. Ford has multiple Field Service Engineers aware of the issue with no fix found. Multiple vehicles not only at one dealership but across the country have confirmed issues. Ford Customer Relations is aware and has an open case with me and many other owners. As requested for Ford case manager, the vehicle is currently going back for a third time to the dealership for something "they can't currently fix".

Significant clunking in the transmission, purchased this 2023 brand new. Ford dealer tells me this is normal but it feels like this truck is going to break down at any moment. Disruptive shifting all over this place, very sloppy. I am also getting excessive exhaust smoke from the tailpipe, almost looks like the truck is on fire every morning when I start it up. Smells awful too. Dealer again states all of this is -??normal-??. Not sure what Ford is compensating dealers with but they are going to have a real issue here soon with upset customers if they keep producing trucks like this.

This is my second F150 that has had severe vibration through the floorboard, steering wheel and gas pedal. The last one the torque converter and steering failed. Both trucks were brand new. This is a serious safety issue. My foot goes numb after about 15 minutes of driving from the constant vibration. Ford acts as this is normal, but this issue has been well documented in the Ford community. There have thousands of similar reports made to Ford Motor Co.

Front differential is bad. First broke it clanked and was banging. Now its a growl/grind under acceleration and deceleration.

While sitting at a traffic light, the gear shift switched to park from drive with my family inside the vehicle. The vehicle would not move and the gear shift continued to switch back to park when I attempted to get out of the roadway, leaving me and my family in a dangerous spot. I have video of the gear shift moving to park.

Battery is bad. Drove truck 4600 miles without issue, went to start truck and battery was dead. Needed to jump start truck, drove for 30 minutes, parked it and measured 12.2V. Charged truck overnight, measured 12.6V. Drove to work 30 minutes, parked 10 hours, drove home 30 minutes, measure battery at 11.08V. I could not start the vehicle and get out of the area I was in.

Took delivery of a new 2023 Ford F-150 on 2/18/2023. Upon inspection once at home I discovered excessive Rust/Oxidation in the underbody area. Specifically, there was excessive rust and oxidation in the following areas: Rear Differential, Rear Axle Casings, Rear Axle Hubs, and portions of the front Frame Rails. This amount of rust/oxidation should not exist in a new vehicle and has the potential to lead to a driving performance/braking incident/accident that could damage the truck and or injure vehicle passengers. Research indicates Ford Motor Company has known about these issues for a couple of years. Furthermore, after contacting Ford, I received a boilerplate email stating that they would look into this problem without indicating whether or not they would issue a Recall or CSP (Customer Service Program) to remediate this problem. This is without question a safety issue and should be investigated by NHTSA. Pictures of the affected areas and a copy of the email from Ford area attached to this filing.
