Car gave me the high voltage fault that many Mach e owners have reported. Car is in the dealership now and I don’t have the car. Why weren’t these recalled?

Filed Oct 9, 2023 · Electrical · NJ

Ford delivered the car with only one key FOB which was corrected in later builds of the car. To fix this they had a program where you could go to your dealer to get the second key FOB for free. I set up an appointment to go to the dealer and was reassured that even though the date was after the expiration of the program I would still get the second key for free. When I went in I was told this was untrue and every Ford representative has told me that even though I was lied to they would not fix things for free as it should be with the program. Eventually I was told to contact the federal safety agency about this issue. I currently have to use my phone as a key which has become increasingly unreliable requiring my backup code often to be entered into the car even when my phone is on and has the Fordpass app open to act like a key. This has caused issues with when I shift out of drive or reverse that it places itself in park asking for the backup code to be entered again before I can continue driving.

I want to draw attention to a significant concern: U.S. auto safety regulators announced in August of this year that they are currently investigating whether Ford Motor's 2022 recall of nearly 49,000 Ford Mustang Mach-E electric vehicles comprehensively addressed the associated safety concerns. The basis for the 2022 recall was that the high voltage battery main contactors could overheat, particularly from DC fast-charging and repeated wide-open pedal events. This overheating presents a very real danger as it could result in an immediate loss of power, markedly increasing the risk of a vehicular accident. Furthermore, after the recall, Ford issued a technical service bulletin, directing the replacement of the High Voltage Battery Junction Box on the recalled vehicles. However, the federal safety agency has since opened a recall query. This action was prompted by 12 consumer complaints related to Mach-E vehicles that had supposedly received the necessary recall fixes. It is worth noting that the High Voltage Battery Junction Box has been replaced on my Mach-E already, and I am still facing problems. This is my third encounter with this particular safety issue.

We came out to our parked car and got a message that said Stop Safely Now. The vehicle would not shift into gear. The dealership had confirmed that the high voltage junction box has failed. We did not get the Service Vehicle Soon warning prior to the failure, despite having had the recall software update applied. The first sign of failure was a loss of motive power. This is a safety issue because loss of motive power while driving can result in loss of control of the vehicle. The loss of heating and cooling combined with the loss of motive power is also a significant safety risk if the failure occurs in a remote location experiencing extreme temperatures. The part has yet to be replaced, but I’m sure Ford will be retaining it for inspection.

Pre collision assist and front camera malfunctions randomly. Dealer did a software update and has not resolved the issue. This happens at least once every time the vehicle is driven. It is out of warranty and will not be covered. This is a problem that plagues a significant amount of vehicles, I follow a mach-e group on social media and it’s a prominent issue. If you’re using blue cruise. The vehicle stops self driving abruptly.

The front camera system has failed. The cables need replacing, which was diagnosed by a Ford dealer. I have no collision assist, no cruise control, no lane keeping abilities, nothing that has to do with the camera in front. This is a known problem that Ford is not admitting to. All years of the Mach-E are having this issue, frequently. It has put myself and others on the road in danger by not being able to function as it should. Every time I turn the car on I get multiple warnings on the dash concerning these issues. This is not the only problem and safety issue I've had with this car in less than 9 months of owning it. Something must be done to hold Ford accountable.

It would appear that after the recall repair my car is experiencing problems that we’re supposed to be addressed with the recall. All systems are constantly malfunctioning.

The charging port on my Mach-E is failing. I am unable to change at the manufacture reported limit of 48 amps. If I try to charge my Mach-E at any rate higher than 32 amps, it will unexpectedly stop charging within 30 minutes, and only change the car 2% or 3% per charging session. Once I derate my EVSE to 32 amps, then my Mach-E can fully charge up to the 80% limit that I have set in the car within a single charge session. Several others have reported the same issue on the following forum post: [XXX] . It seems to be an issue with the temperature sensor in the charge port failing prematurely. I can confirm that the charging issue can occur outside of environmental factors like during a hot summer day. I usually charge during the late evening and at night, around 8:00 p.m. to 12:00 a.m., and the car always stops charging within 30 minutes. I have even charged successfully at a public L2 charger during the day when the charging cord handle was in direct sun light, and was hot to the touch. So the failure seems directly related to the charge rate. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Began to receive error messages stating "Front Camera Fault" and "Forward Collision Detection Fault". For a while it fixed on its own, then the messages started to become more and more frequent until now the error messages come up every time we turn on the car. With the malfunction that is happening with front camera and collision detection, it prevents cruise control from being used (which is adaptive) and forward collision warnings are not working/inactive. The lack of both of these systems presents a safety issue. The car has been taken to the local Ford dealership which has determined what needs to be replaced (the front camera and cables connecting the camera). However the parts must come from the Ford manufacturer and there is current no ETA that the dealership is being given for the parts to be delivered. When searching online for this issue, there are other owners that have experienced this and there is currently a TSB for this issue (TSB 23-2155).

Ford has installed a sub par HVBJB in my car which was manufactured in 12/01. In lieu of replacing the poorly designed unit they have added software that does not guarantee that the car will not brick. Numerous car have failed and I am afraid of having my wife drive the car at night for fear of it breaking down. This is a ticking time bomb.

I am filing this complaint regarding the potential failure of the High Voltage Battery Junction Box. There have been many failures reported on the forums some experiencing multiple failures. Ford provided a software update that supposedly predicts an impending failure reducing available propulsion power. I do not feel comfortable driving a vehicle with a ticking time bomb. Losing propulsion power while driving at highway speeds could result in a serious safety senerio. I would like to see Ford provide a real fix.

Filed Aug 22, 2023 · Electrical, Fuel system · NV

The HVBJB subassembly in ALL Ford Mach-e vehicles has known defects with 'under-designed' main contacts that are known to fail under normal charging and driving conditions as outlined in current open Ford recall notice. Unfortunately, the internal damage to contactors is not visible externally, and warning notices on display only AFTER the damage has occurred, and can result in sudden loss of propulsion power at highway speed, loss of power steering, and power brakes... and failure of other 12v systems due to failure to charge the 12v battery properly after contacts are damaged. Less catastrophic results can include failure to start; which can 'strand' driver's and passengers in remote areas, bad weather conditions, as well as cause loss of use for weeks due to delays in replacement parts and local Dealerships needing equipment and training to effect removal/replacement of faulty unit with a new HVBJB having re-designed 'beefier' components.​ ​ My complaint is that Ford's recall notice 22s41 is a software-only attempt to prevent future damage, and does not require removal of the part(s) which are KNOWN TO FAIL to be replaced with the re-designed components which are available, and have been used to repair failures under warranty. I have no way of inspecting the original equipment to evaluate current condition; and failure can result in sudden and unexpected loss of power, steering, and braking as well as potentially 'stranding me' in unsafe conditions unable to re-start my vehicle.​ ​ I would like to see the federal safety agency strengthen the Ford recall to include both improved software AND removal/replacement of the HVBJB sub-assembly with the new 'beefier' parts.​

After receiving the remedy to the federal safety agency campaign 22V‑412 on Aug 5, 2022 via a Ford Power-Up over-the-air update, my high-voltage battery contactors still overheated and failed on Oct 25, 2022, requiring warrantied replacement by my Ford dealer on Oct 27, 2022.

On Friday 8/18/23 I was driving down a major freeway and my Mach-E jolted violently. I then received a "Stop Safely Now" and "Service Vehicle Soon" message. The vehicle lost all power at this time. Being on a very busy freeway my safety was at risk and I was luckily able to coast over to the right shoulder. The car refused to "start" after pulling over however the 12v battery did work so I was able to use accessories. Once towed to the dealer I was able to confirm a P0AA2 TSB code that indicated that a conductor was stuck open on the high voltage junction box. This was supposed to be fixed by a previous recall software update that FORD uploaded to my car however that was not the case. I am now without a car for 2 weeks but more importantly I am concerned for the safety of other Mach-E drivers as I am reading that this can happen again even after a hardware fix.

I had my 2021 Mustang Mach-E updated with the recall software last year. In July of 2022, my High Voltage Battery Junction Box (HVBJB) still failed, giving me a service vehicle soon and SEVERELY reducing power WHILE driving. I was on the freeway and my car just started reducing speed since I was trying to pass someone and I almost hit them. I received the new HVBJB from my dealer and had been fine since. Then a couple of weeks ago, I received the errors AGAIN with this "new and improved" HVBJB that Ford said is more robust and not supposed to fail. Same thing, on the same freeway I commute (73 toll road in California). I was passing someone and the car hit me with all these errors and SIGNIFICANTLY reduced my power. Like 66% reduction. I had to get back into my lane and was able to get back a safe speed but you basically have no power to pass. This is unacceptable. I received the "new" part and yet get a failure AGAIN? On a normal commute, not at the track, accelerating to show off the EV acceleration, just DRIVING! Please make them fix this for real. My dealer said there was a new bulletin that came out after my first repair that has an updated part number, but it is not a true revised part, meaning the internals are actually differnt, it is more a housekeeping part number update due to something as simple as the sticker being in a different spot, some backend thing, etc. There has been no revision to the components that fail since they "fixed" the part back in 2022.

I was driving on the highway (12) in Mandeville, Louisiana and the car (a 2021 all electric Mustang Mach E with only 13k miles) flashed a 'Stop care safely now' sign and then proceeded to power down within 3 seconds of the message. I exited (luckily I was at my exit) and felt the car lose power on the exit ramp. Three signals came up (battery - yet I was at 100% - then a turtle mode and not sure what the third symbol was) and then the car locked up - went into park, would not move or allow me to put into neutral to pull off a very busy highway ramp. I was forced to a dead stop on the ramp (very dangerous). I put on my hazard lights but cars still pilled up all around me, beeping etc. at high rates of speed. I called 911 and the police came out (took about 10 minutes during which time I had to direct traffic around me - again very dangerous) and asked that I move the car but the car would not move or even go into neutral. A DOTD tow truck towed me to a nearby Winn Dixie and then the roadside assistance towed to the Ford Dealer. The Ford Pass app send me the message attached below that said it was forcing a software update and the car would not be able to be used during this update - while the car was in drive and while I was driving it down a four lane highway! Very unsafe considering the car was connected to WIFI at home and that update could have been done at any time - not while driving. There was no notice prior to this that a software update was needed and we have it set for updates to happen at 1 am. The car relies upon software (not firmware) to run and if that fails, the car just locks up. This car should be recalled. I am lucky no one was injured including me trying to direct traffic on a busy high speed highway ramp. The policeman was very frustrated and made me get out of the car. Then the DOTD driver confirmed it would not budge. Thank God this didn't happen while I was in the middle of a 4 lane highway. It would have been like stopping on a train track.

Erratic behavior when semi-autonomous Blue Cruise engaged. Fault may be due to failures/malfunctions in side view mirror camera modules.

Filed May 3, 2023 · Driver assistance, Electrical · OK

I have been having an intermittent warning error saying my front camera is faulty and my lane assist is no longer operational. The error seemed to come and go with bumps. Here recently it has become permanent around the beginning of April 2023, and I no longer have functionality of many safety features including adaptive cruise control, regular cruise control, lane assist, crash prevention warning, automatic braking, or even regular cruise control (if I try to turn off the adaptive cruise in the settings regular cruise control still does not work), automatic bright lights don't work. I have been trying to get this resolved since I purchased the car but despite a dozen or so trips to the dealership I cannot seem to get it fixed. I've attached a screenshot of some of the dozens (hundreds?) of error messages I have received through the Ford app with the car, which note pre-collision assist is not available. It does not seem safe to have so many safety features non-operational.

I went to start the vehicle and it gave me a red warning "stop safely now". It was already stopped and would not start at all. It had plenty of charge on the battery pack. It's been at the dealer for nearly two weeks and they have had to order the HVJBC, I believe. I am fortunate that it didn't fail while driving or parked in a place which was inaccessible to a tow truck. The forum I read recommended making a report. This seems to be an all to common problem with this car and can lead to sudden acceleration or deceleration while in motion. Had had received an earlier yellow warning for "service vehicle soon" and took it to the dealership and they assured me they had updated all the software (in the hopes of preventing the "stop safely now" problem). Obviously, that didn't work.

Unintended acceleration from a stop when pushing accelerator. Has happened 2 times in the last 2 days. I touched the throttle from a stop 2 time and it took off like I put the accelerator to full throttle (which I didn’t). Very dangerous situation in parking lots or around pedestrians. I have scheduled an apt with my local dealer.

Ford released an OTA update for the HVB issue Mach-E were having and leaving drivers stranded. I have seen that even with the update many people are still having the cars break down while driving and needing the High Voltage Battery Connector replaced. I am worried that this may happen to my car one day while driving and could cause an accident or death. Is there anyway to force Ford to fix every car that had this issue before we break down? The temporary fix of software is not good. I think FOrd should be forced to recall all Mach-E and replace the connector before there is an accident that leads to deaths on the road.

Occasional blank/inoperative info screen, typically recovers after reset or re-start, but sudden loss of visibility of ALL settings and controls for heat, navigation, and most importantly loss of the ability to enter backup Start code for keyless start can cause possible stranding in dangerous conditions. Loss of control of heating/cooling could cause loss of visibility if defrost is unavailable, or heat stroke if air conditioning is unavailable. My understanding is that re-designed console screens are available to address this known defect in vehicles built prior to June 2022, but no recall has been issued.
