My car displayed a warning that the pre-collision assist was not available. This caused all of the safety features not to work (collision warning; lane departure warning; parking collision warning etc.) The car has been in and out of the dealership since Aug. 6th to repair this but Ford has not corrected the problem. We have not been told what is wrong with the car or any estimation on if or when it will be repaired. I requested the service documents for all of the records of when my car has been in the shop for this issue. I received the document but it has incorrect and missing information which causes me to be concerned that the issue is not being address but instead my car is being held with no efforts of a remedy. My car has not operated correctly for almost 2 months but the only service recorded was a replacement of a coaxial cable which did not fix the car.

Upon vehicle startup, the speedometer does not show on the instrument cluster (completely digital readout, analog readout not possible). In its place is the EV's remaining battery % with absolutely no way to access the speedometer and know the speed of the vehicle. This places the driver, other drivers, pedestrians, anyone else on the road at risk of excessive vehicle speed. There is no warning, error messages, or other symptoms prior to the issue happening. The only way rectify the issue is to fully restart the vehicle. However, this is not always a guaranteed fix, and the problem may persist between starts up. The issue does not occur during every start up event and is intermittent with a sudden onset (had the vehicle for 1.5 years at this point). The issue has occurred 3x in the last 2 weeks now. This issue appears to happen to other drivers of the same make / model and varying model years according to several other sources: (link 1) [XXX] (link 2) [XXX] (link 3) [XXX] (link 4) [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 2 occassions in the past 2 week, our Mustang Mach E has accelerated on its own. In the first incident, it was a minor acceleration. It caught me by surprise as I was pulling up to a curb to drop off a passenger. It was easily stopped with brake pressure. In the 2nd incident, the acceleration was greater and more pronounced while pulling into a parking spot, requiring the pressure of both feet to quickly stop it before it went up onto a sidewalk and into a store front. It's never done this before, but certainly could cause an accident and was unsettling. We have not taken it to the dealer because it is random and not replicate-able. There were no warning lamps or error messages at the time. The vehicle was functioning and acting normal otherwise.

EA25001 · Collisions Involving Ford Bluecruise

Opened Jan 17, 2025 · No close date supplied

Status: open (inferred from source dates) · Electrical System:adas

On April 25, 2024, NHTSA’s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24012) to assess BlueCruise, a partial driving automation system available on certain vehicles manufactured by Ford Motor Company (Ford). NHTSA opened the investigation after the agency received notice of two fatal collisions involving BlueCruise-equipped Ford Mustang Mach-E vehicles. Based on the incidents, NHTSA scoped the investigation to 2021-2024 Mustang Mach-E vehicles equipped with BlueCruise. In June 2024, ODI sent an Information Request (IR) letter to Ford requiring that it provide certain information pertaining to crashes, non-crash reports, and technical specifications that relate to BlueCruise, as well as other Ford partial driving automation systems that offer lane and speed maintenance. In its response to ODI’s IR, Ford stated that there are 2,539,962 Ford and Lincoln vehicles (including subject and peer vehicles) equipped with a partial driving automation system within the scope of the request. The majority of these vehicles are equipped with a system that Ford calls Lane Centering Assist (LCA), which is a hands-on partial driving automation system that combines longitudinal control authority governed by Adaptive Cruise Control (ACC) and lateral control authority governed by a steerable path. LCA is offered on a wide range of Ford and Lincoln models beginning in model year 2019. Vehicles that are equipped with BlueCruise, the focus of this investigation, have LCA capability and additionally offer hands-free partial driving automation when certain conditions are met. Hands-free BlueCruise operation is only offered on certain roadways and system availability is geofenced using vehicle GPS. BlueCruise-equipped vehicles employ a camera-based driver monitoring system to determine driver attentiveness to the roadway. BlueCruise was introduced in model year 2021 and is currently available in a select range of Ford and Lincoln vehicles. For BlueCruise- and LCA-equipped vehicles, both ACC and Pre-Collision Assist (PCA) features use a combination of camera and radar sensing technologies to detect and classify objects. ACC is specifically designed to detect vehicles (including cars, trucks, and motorcycles) and bicycles in front of the subject vehicle which are either stationary or moving in the same direction as the subject vehicle. Through this investigation, limitations in the detection of stationary vehicles in certain conditions have been identified. Specifically, due to the potential for false detection of stationary objects at long distances, Ford designed ACC to inhibit any response to reported stationary objects when the subject vehicle’s approach speed is at or above 62 mph. Additionally, system performance may be limited when there is poor visibility due to insufficient illumination. In addition to reviewing Ford’s response to ODI’s IR, the agency conducted a review of crash and non-crash reports identified collectively through Ford’s IR response, incident reporting through Standing General Order 2021-01 (SGO), and NHTSA vehicle owner questionnaires. In total, 32 crashes and 2,004 non-crash reports on subject and peer Ford vehicles were identified across manufacturer and ODI data sources. A detailed analysis of each crash was conducted including the review of any available police reports, photographs, data recovered from in-vehicle event data recorders, connected vehicle data, and/or other information. In both fatal collisions referenced in the PE24012 opening resume, the subject Ford Mustang Mach-E vehicle was traveling over 70 mph on a controlled-access highway during nighttime lighting conditions with hands-free BlueCruise engaged when it collided with a stationary vehicle. Analysis of data imaged from the vehicles’ event data recorders demonstrates that in each incident, the driver did not apply the brakes or take evasive steering action, and no deceleration was initiated by either the BlueCruise system or PCA prior to impact. Through the agency’s crash analysis, four additional frontal collisions were identified where the subject Ford impacted a stopped or slow-moving lead vehicle or another stationary object located in the travel lane. Two of these four incidents involved BlueCruise-equipped Ford Mustang Mach-E vehicles (included in the failure report summary along with the fatal collisions discussed above), while the other two involved other Ford models equipped with the LCA system. Additionally, a trend was identified through analysis of the non-crash reports relating to allegations that ACC (the longitudinal component of both BlueCruise and LCA) failed to detect and/or respond to a stopped or slow-moving lead vehicle. In these reports, consumers often describe that the absence of deceleration initiated by ACC was unexpected and required harsh manual braking or intervention from the PCA to avoid a frontal collision with the lead vehicle. Based on NHTSA’s analysis, system limitations relating to the detection of stationary vehicles while traveling at highway speeds and in nighttime lighting conditions appear to be factors in collisions under investigation and several apparently similar near-miss, non-crash reports. This Engineering Analysis (EA) is being opened to further investigate these system limitations and to evaluate drivers’ ability to respond to scenarios that exceed system limitations. During the EA, the agency expects to, among other things, perform vehicle evaluations, review additional technical information, and perform additional analysis of related crashes and non-crash reports. The crashes included in the failure report summary can be found at NHTSA.gov under the following SGO report identification numbers: 502-7268, 502-7426, 502-6852, 502-8738.
