Insufficient Welds In Ford Escape And Lincoln Corsair High Voltage Batteries

Posted on by

The high voltage batteries in certain 2020 Ford Escape and 2021 Lincoln Corsair vehicles may have been manufactured with insufficient welds that could fail and cause a loss of drive power. These vehicles are equipped with 2.5L hybrid powertrains.

Ford’s Critical Concern Review Group first became aware of the problem in February 2022 when they were informed, by the supplier, that there was an issue with the weld penetration on the bus bars of certain high voltage batteries. A review of the manufacturers’ records showed that the suspect cause of the problem was damage to the laser cooling line caused by maintenance of the laser air knife. The damage to the laser cooling line resulted in an out-of-control weld process and insufficient welds. The suspect time period was between June 6, 2020, and June 12, 2020.

According to the safety report, insufficient weld penetration between the bus bar and cell terminal could result in a loss of electrical contact at the bus-bar weld joint inside the high voltage battery. Loss of electrical contact will result in a loss of motive power and an increased risk of an accident.

The vehicle warning display will illuminate a “Stop Safely Now” message, a wrench lamp, and an audible alert when the vehicle loses motive power.

Owners receiving notices will be asked to take their vehicle to their Ford or Lincoln dealer to have the High Voltage Battery replaced. The new High Voltage Battery LX68-10B759-R will have a bus bar that has proper weld penetration. The supplier repaired a damaged coolant line on June 27, 2020. High voltage batteries produced after June 27, 2020 were produced with sufficient bus bar weld penetration. Ford’s number for this recall is 22S33 and the NHTSA campaign number is 22V-331.

2021 Ford Expedition and 2021 Lincoln Navigator Under Hood Fire Warning

Posted on by

Ford Motor Company (Ford) has decided that a problem affecting vehicle safety exists in certain 2021 Ford Expedition and 2021 Lincoln Navigator SUVs built between December 2020, and April 2021. The vehicles built during this time have an increased risk of under-hood fires.

Ford became aware of the problem in March 2022 after receiving eight reports of under-hood fires. One of the incidents described a melted battery junction box (BJB) on a 2021 Expedition vehicle. Ford’s Critical Concern Review Group (CCRG) opened an investigation into the fires and found that six (6) of the eight (8) fires originated on the passenger side rear engine compartment area, while two (2) had an unclear under-hood origin. Of the eight fire allegations, six occurred while the vehicle was parked and off, and two occurred while driving. Reviewing the incidents, CCRG noted that almost all the vehicles were owned by rental companies.

Ford continues to investigate the cause of the fires, which are believed to originate in the passenger side rear engine compartment area. As of May 12th CCRG is aware of sixteen (16) potentially related reports of under-hood fires on 2021 Expedition and 2021 Navigator vehicles. Of those sixteen (16) reports, fourteen (14) are rental vehicles and two are retail units. Of the sixteen (16) reports, twelve (12) occurred while the vehicle was parked and off, (1) occurred while parked and on, and three (3) occurred while driving. All sixteen (16) vehicles were produced between December 19, 2020, and April 20, 2021. (This period was found to be significant.)

Warning: Owners are advised to park their vehicles outside and away from structures while Ford continues their investigation.

Note: Some customers have reported a burning smell and smoke from the front passenger engine compartment while driving.

Letters notifying owners of the safety risk are expected to be mailed on May 23, 2022. A second letter will be mailed once a fix for the problem is available. Ford’s number for this recall is 22S36 and the NHTSA campaign number is 22V-346.

Ford Escape And Lincoln Corsair Hybrid High Voltage Battery Failure

Posted on by

A small number of 2021-2022 Ford Escape and 2022 Lincoln Corsair hybrid power-train SUVs have been manufactured with a high voltage battery that could fail and result in a sudden loss of motor power. The problem was brought to Ford’s Critical Concern Review Group in October 2021 after an issue pertaining to an overheated high voltage battery bus bar was reported in Germany. Through a search of warranty reports, Ford identified an additional vehicle in Europe that reported a loss of function due to the overheated high voltage battery bus-bar.

During the manufacturing process, the high voltage bus-bar pad was not properly seated and could cause the pad to be mounted out of position prior to bus-bar welding. This condition could reduce the contact area between the cell terminal and the bus bar, giving it a high resistance. The high resistance could eventually result in an overheat situation.

According to the defect report, an overheated bus bar terminal may create a high resistance connection that could cause the battery pack high voltage bus voltage to fall below an operational level. If this happens, the hybrid power-train control module will sense the high voltage and detect a fault. A diagnostic trouble code will be sent and the vehicle will lose power. Drivers will also notice a “Stop Safely Now” warning message displayed on the instrument panel.

Ford’s team reviewed supplier process and production records to determine the population of affected parts. Affected vehicles are equipped with the 2.5L Hybrid power train and the suspect high voltage battery pack.

Dealers will replace the high voltage battery. Ford’s number for this recall is 21S48 and the NHTSA campaign number is 22V-149.

Brake Master Cylinder Leak In Ford And Lincoln Trucks

Posted on by

Certain 2016-2018 Ford and Lincoln, trucks and SUVs equipped with 3.5L Ecoboost engines could require more braking effort and distance to stop the vehicle. Ford will be asking owners to return to their dealerships for repairs.

In May 2016, Ford issued a recall (16V-345) for F-150s equipped with the 3.5L Ecoboost engines, because the brake master cylinder could leak and allow brake fluid from the front wheel circuit into the brake booster. After continued field data monitoring and discussions with NHTSA, Ford issued a second recall (20V-332), to extend the population for F-150s.

Ford continued to monitor field reports expanding the coverage into Ford Expedition and Lincoln Navigator vehicles built during the same period. These vehicles share a similar brake master cylinder design as the F-150 3.5L Ecoboost vehicles

Investigation into supplier records and discussion with the supplier identified additional steps taken by the supplier to further improve brake master cylinder seal installation from August 2016 to December 2016. These include an automated process to remove imperfect threads from the master cylinder outlet port, as well as actions to improve the installation of the rearmost cup seal in the master cylinder. Master cylinders with these improvements were incorporated into vehicle production by January 31, 2017.

In March 2022, Ford’s Field Review Committee reviewed the concern and approved a safety
recall action. Ford is aware of 4 low-speed/low-impact accident allegations with no injuries.

Vehicles manufactured with these defective fuel injectors include:
2016-2017 Ford Expedition
2016-2018 Ford F-150
2016-2017 Lincoln Navigator

Dealers will correct the problem by replacing the brake master cylinder. If the master cylinder is leaking, the brake booster will also be replaced. This recall is an expansion of NHTSA recall number 20V-332. Ford’s number for this recall is 22S11 and the NHTSA campaign number is 22V-150.

Ford & Lincoln Rear End Grinding Noise

Posted on by

In December 2020, Ford opened an investigation into a Ford engineering vehicle that experienced a rear drive unit seizure. The final analysis found that the seizure was the result of inadequate lubrication and that a malfunction during the rear drive unit lubricant fill procedure was the cause of the miss-fill.

As a result, Ford will be recalling certain 2020-2021 Ford and Lincoln cars and trucks.

Vehicles Affected Include
2021 Ford Bronco Sport
2020-2021 Ford Edge
2020 Ford Escape
2021 Lincoln Corsair
2020 Lincoln Nautilus
WARNING: Drivers may hear a metallic grinding or whining sound from the rear of the vehicle prior to a rear drive seizure.

Ford will notify owners, and dealers will check the rear drive unit lubricant level. Axles found to have lubricant at the minimum level will be filled to the full level. Axles found to be below the minimum lubricant fill level will be replaced. Ford’s number for this recall is 21S02 and the NHTSA campaign number is 21V-011.
