2021 Ford Edge

On July 22, 2022, the Office of Defects Investigation (ODI) granted a Defect Petition (DP22001) and opened a Preliminary Evaluation (PE22007) to investigate allegations of loss of motive power in model year (MY) 2021 Ford Bronco vehicles equipped with 2.7L EcoBoost engines. Complainants were reporting sudden engine failure while driving resulting in a loss of motive power, often without the ability to restart. During PE22007, the cause of engine failure and loss of motive power in the subject vehicles was determined to be intake valve fracture, and the full scope of vehicles affected by the subject defect was identified as all MY 2021-2022 Ford and Lincoln models equipped with either the 2.7L or 3.0L EcoBoost engines, referred to as the “Nano” engine family.  If an intake valve fractures in the subject engines, it may drop into the cylinder and contact the piston, often resulting in catastrophic engine damage. On September 29, 2023, PE22007 was upgraded to an Engineering Analysis (EA23002) to further investigate the subject defect across the full scope of affected vehicles. During EA23002, ODI visited Ford facilities to review technical information related to intake valve fracture in “Nano” engines, coordinated with NHTSA’s Vehicle Research and Testing Center (VRTC), and analyzed updated field data relating the subject defect. Forensic analysis of fractured intake valves demonstrated that the defective components exhibited “grinding burn” or out of specification hardness in the area of the keeper grooves. The presence of grinding burn is evidence that during the groove grinding phase of production, the temperature of the valve became sufficiently high to alter the microstructure of the material and is indicative that the valve supplier’s manufacturing processes were not within control specifications. Grinding burn results in a hard, brittle microstructure and high residual stresses toward the surface of the valve. Through normal engine loading, a valve with grinding burn will likely fracture at the area of highest vulnerability, which is the third keeper groove. In its response to the EA23002 Information Request (IR) letter, Ford provided evidence of 396 customer complaints (including field reports), 825 warranty claims, and 936 engine exchanges. When considering both ODI and manufacturer failure report data, there have been reports representing 1066 unique vehicles within the subject vehicle population. Analysis of the failure report data demonstrates that vehicles equipped with potentially defective intake valves were built within a production “spike period” of May 2021 – October 2021. The beginning of the spike period corresponds to a ramp up in production at the valve supplier manufacturing facility, and the end of the spike period aligns with the implementation of several mid-production process improvements and the decision to change the metal alloy used to produce intake valves from “Silchrome Lite” to “Silchrome 1”. Ford began investigating the subject defect in July 2021, determined the root cause, and took corrective measures for the new production vehicles. Analysis of the failure report data demonstrates that these corrective actions were successful in eliminating the risk of intake valve fracture for subject vehicles produced after October 2021. However, Ford did not take any field action to address vehicles produced during the spike period, and in the several months following the implementation of the production changes, a significant number of field failures continued to occur. It is Ford’s assessment that not all valves produced during the spike period are defective, and that failures associated with the subject defect occur at low time in service. Analysis of the failure report data demonstrates that the vast majority of failures have occurred before 20,000 miles with over half of all reported failures occurring before 5,000 miles. The rate of reported failures related to the subject defect has steadily decreased since November 2021. ODI coordinated with NHTSA’s National Center for Statistics and Analysis (NCSA) to conduct statistical analysis and predict the number of future failures associated with the subject defect. The results of this analysis, and the trends identified through the failure report data are generally consistent with Ford’s assessment that defective intake valves will likely fail at a low time in service and indicate that the majority of subject vehicles equipped with defective valves have already experienced a failure. On August 23, 2024, Ford submitted recall 24V635 for subject vehicles equipped with “Nano” engines and built within the production spike period identified above (total population 90,736 vehicles). The remedy includes an inspection at a Ford/Lincoln dealership where the lifetime engine cycles of the vehicle will be determined. If a vehicle does not meet a threshold for lifetime engine cycles, the dealership will conduct a high RPM engine cycle accumulation procedure, which aims to identify if the vehicle is equipped with defective intake valves. Any vehicle that fails the accumulation procedure will receive an engine replacement under the recall. In addition to recall 24V635, Ford has stated that it will launch customer satisfaction campaign 24N12, which will provide extended warranty coverage to the subject vehicles through the earlier of 10 years or 150,000 miles. In view of the recall action being taken by Ford, ODI is closing this Engineering Analysis.

The left rear axle housing due to not enough lubricant. The ford maintenance shop states they can refill the lubricant but it doesn’t last long and will be back in the shop . So I’m having it replaced due to their recommendation which is a $1,835.00 fix. I see there were recalls on 2021 edges but mine wasn’t built in the right time frame apparently and it’s ironic that it is the same exact problem with several 2021 Edges but yet only the ones built in certain months are getting recalled. Makes no sense that if this is hazardous then for safety reasons shouldn’t there be a recall on all of them no matter where or what month they were built. Very disturbing and disappointing. It sure sheds some light on the Ford manufacturing!

The vehicle hesitates, bucks, and surges when accelerating from low speed making it difficult and hazardous merging into traffic and other driving situations. The hesitation, bucking, and surging is getting progressively this happened around 70k miles. The mechanic is saying it needs to be replaced completely for 12k!

The transmission failed causing the car to sputter and stop. My daughter was driving the car at the time and it died while she was waiting for a light to turn green at a major intersection. She had to wait for my husband to come assist her. We had it towed to McCree Ford in Dickinson, TX. They indicated it was the transmission and it would need to be replaced. No indication of any issues prior to this incident. The car was well maintained up until this incident and we were just short of 100,000 miles. Mostly highway miles.

The contact owns a 2021 Ford Edge. The contact received notification for NHTSA Campaign Number: 26V124000 (Back Over Prevention); however, the part to perform the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The vehicle was taken to a dealer, where the contact was informed that the USB port needed to perform the software update was defective. The dealer did not provide the alternative option included in the recall remedy, which authorized an over-the-air (OTA) software update free of charge. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The contact had not experienced a failure.

Some 2021-2026 Ford/Lincoln vehicles may exhibit various symptoms including but not limited to the auto start/stop system not operating as intended with a "Check Charging System" message in the instrument panel cluster (IPC) while the charging system is operating properly with no charging related diagnostic trouble codes (DTC) stored. This may be due to someone using an aftermarket programmer to change the body control module (BCM) configuration to disable the auto start/stop system or perform other unsupported programming modifications. To correct this condition on F-150 and Bronco vehicles, download and run the Ford Diagnosis and Repair System (FDRS) application titled "BCM-Charging System Configuration Correction". Running this application will determine if the BCM configuration was modified by the customer and if so, provide the option to return the configuration back to factory settings. For other vehicle models exhibiting concerns related to unsupported aftermarket BCM programming, submit a Technical Support Request (TSR) requesting support to revert the BCM configuration
