Software Error Could Result In An Unexpected Vehicle Roll-Away

Posted on by

Automobile manufacturers Hyundai and Kia will be asking owners of certain 2022 Hyundai Ioniq 5 and 2022 Kia EV6 vehicles, to return to their dealerships for a problem affecting the parking brake mechanism. A software error in the Shifter Control Unit (SCU) may disengage the parking mechanism and allow the vehicle to roll away.

Hyundai and Kia first became aware of the problem in April/May 2022 after reports about warranty claims involving some Ioniq 5 and EV6 vehicles in Korea. The vehicles allegedly unexpectedly rolled away after being parked on an incline with the ignition off. Further investigation into the incidents found voltage fluctuations in the electrical system that could affect the command signal from the Shifter Control Unit (SCU) to the parking actuator. The result would be a momentary disengagement of the parking pawl.

According to the safety report, the subject vehicles are equipped with a shift-by-wire system with a shifter control unit and parking pawl actuator motor. If a voltage fluctuation occurs when the vehicle is off and in Park, the signal from the SCU to the actuator may be affected. The problem could result in the temporary disengagement of the parking mechanism and a potential vehicle roll away.

Owners will be asked to return to the dealerships to have the Shifter Control Unit software updated. Drivers are recommended to use the Electronic Parking Brake (EPB) when parking their vehicles until the software update has been performed. Hyundai’s number for this recall is 228 and the NHTSA campaign number is 22V-324. Kia’s number for this recall is SC236 and the NHTSA campaign number is 22V-332.

Tesla Center Screen Display Is Lagging Or Completely Blank

Posted on by

Tesla will be contacting the owners of certain 2021-2022 Tesla model vehicles because of a problem that could cause the infotainment central processing unit (CPU) to malfunction.

The vehicles affected by this problem include:

2022 Tesla Model 3
2021-2022 Tesla Model S
2021-2022 Tesla Model X
2022 Tesla Model Y

In December 2021 during routine High Temperature Operation Endurance (HTOE) testing on the Model 3 and Model Y vehicle platform central processing unit (CPU), throttling was detected from thermal protections being engaged. An investigation into thermal management was initiated using vehicle alerts to follow the condition in the field. During this time, Tesla Engineering worked on a series of test experiments to identify the potential cause of the overheating condition. In April 2022, Tesla completed its investigation and confirmed the suspected root cause and affected vehicle population. The findings were reviewed and a recall was initiated.

According to the defect report, during fast-charging or preparation for fast-charging, the infotainment CPU may not cool sufficiently. Higher than expected temperatures could cause the CPU to slow processing or restart, and a lagging or blank center screen display. The problem could cause the rear-view camera display, windshield visibility control settings, drive modes (i.e., Drive, Neutral, or Reverse), and telltales to be unavailable.

On May 3, 2022, Tesla began deploying an OTA firmware update that will improve the management of the CPU temperature and associated communications with elevated temperature operation. This remedy will mitigate temperature elevations in the CPU when the vehicle is fast-charging or preparing to fast-charge, which will prevent slow processing or restart. Tesla’s number for this recall is SB-22-00-009 and the NHTSA campaign number is 22V-296.

Ford F-150 Transmission Shifts Into Neutral While Driving

Posted on by

Some 2021 Ford F-150 trucks could unexpectedly shift into neutral while driving. The unexpected loss of engine power could increase the chance of an accident.

In February 2022, an issue was brought to Ford’s Critical Concern Review Group (CCRG) about certain 2021 F-150 vehicles equipped with 3.5L GTDI, 2.7L, and 5.0L engines, along with the 10R80 transmission. These trucks were experiencing an increase in Transmission Fluid Pressure along with a Transmission Fluid Pressure Low Diagnostic Trouble Code (DTC) of P0868. This DTC would falsely activate and cause the transmission to shift into a neutral state while the truck was driven. Once the false activation occurs, the vehicle will coast to a stop and the electronic shifter will attempt to engage Park. Once the vehicle comes to a complete stop, the electronic shifter will automatically shift into Park.

According to the engineering investigation, one of the power-train diagnostic logic software branches was turned on in error when these vehicles were produced. Under certain conditions, this diagnostic logic could inadvertently activate the pump gear failure detection logic even though the hardware is still functioning properly. When this happens, the transmission on-board diagnostics will set the DTC P0868, turn on a Wrench Light telltale, and the vehicle’s transmission will shift into a neutral state. As the vehicle slows to a speed below 2 mph/3kph, the electronic shifter will attempt to engage the Park function and will automatically shift into Park when the vehicle comes to a complete stop. The transmission function can be restored by a key-off/key-on cycle.

Between October 2021 and February 2022 there have been 28 warranty claims and one Customer Contact Center report to Ford that potentially related to this concern.

Dealers will correct the problem by updating the Power-train Control Module (PCM) software. Ford’s number for this recall is 22S15 and the NHTSA campaign number is 22V-188.

Unreliable HV Battery Connection May Cause 2021 VW ID.4 To Stall & Not Start

Posted on by

Volkswagen Group of America, Inc. (VW) will be asking a small number of 2021 VW ID.4 electric crossover SUV owners, to return to their dealerships because of a problem affecting the solder connections inside the HV battery of their vehicles. This defect could result in a stall and may increase the risk of an accident. A fix for this problem is still under development by the manufacturer.

VW became aware of the defect in January 2021 when the first known field case occurred outside the U.S. VW quality and safety departments began to monitor the field reports for the nature and frequency of the non-starting condition and found reports of similar problems in other brand vehicles using the same or similar battery systems. During a multi-brand clearing committee meeting, impacted brands shared information on the potential stall while driving cases and decided to conduct a recall. Volkswagen will be conducting a recall on 351, 2021 VW ID.4 vehicles in the U.S. that contain the potentially affected parts.

According to the defect report, a manufacturing problem with the high voltage (HV) battery may have caused incorrect soldering on specific points of the flexible printed circuit assembly (FPCA). The amount of solder contact points of the FPCA is not sufficient and the thickness of the solder layer is out of tolerance parameters. The result is an unreliable connection inside the HV battery that could lead to a breakdown or stalling while driving. If this issue is present in the vehicle, the driver will be alerted by a high voltage system warning message in the instrument panel.

Owner notification letters about the defect are expected to be mailed by May 13, 2022. Volkswagen’s number for this recall is 9302 and the NHTSA campaign number is 22V-1562.

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.

NHTSA Investigates Unexpected Braking In Honda And Tesla Vehicles

Posted on by

Automotive Defect Investigation

The NHTSA Office of Defects Investigation (NHTSA) has opened two separate investigations related to unexpected breaking in certain Honda and Tesla vehicles. These vehicles are equipped with collision mitigation braking systems (CMBS) or advanced driver assistance systems (ADAS), which visually and audibly alert the drivers of a potential collision. Under certain circumstances, the system will automatically apply the brakes to help reduce the force of an unavoidable collision.

The problem of unexpected braking has been called “Phantom Braking”. Phantom braking is when a vehicle’s brakes activate unexpectedly even when traffic is flowing normally or there is no obstacle to avoid.

Inadvertent Automatic Emergency Braking
2017-2019 Honda CR-V and 2018-2019 Honda Accord
NHTSA Investigation Number: PE22003

The NHTSA has received a total of 278 complaints and several Early Warning Reports alleging unexpected activation of the collision mitigation braking system (CMBS) in some 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. Driver complaints include high-speed braking incidents occurring with nothing obstructing the vehicle’s path of travel. Of the 278 complaints, 6 allege a collision with minor injuries.

Inadvertent or unexpected braking activation while driving can cause unexpected speed reductions that can lead to increased vulnerability to rear-end impact collisions. The complaints allege that the inadvertent braking events occur without warning and randomly.

Unexpected Brake Activation
2021-2022 Tesla Model 3 and 2021-2022 Tesla Model Y
NHTSA Investigation Number: PE22002

The NHTSA has also received 354 complaints alleging unexpected brake activation in 2021-2022 Tesla Model 3 and 2021-2022 Tesla Model Y vehicles.

Driver reports have been characterized as “phantom braking”. Tesla describes the subject vehicles as equipped with a suite of advanced driver assistance system (ADAS) features referred to as Autopilot which Tesla states will allow the vehicle to brake and steer automatically within its lanes.

The complaints allege that while utilizing the ADAS features including adaptive cruise control, the vehicle unexpectedly applies its brakes while driving at highway speeds. Complainants report that the rapid deceleration can occur without warning, at random, and often repeated in a single drive cycle.

These investigations are a Preliminary Evaluation (PE) to determine the scope and severity of the potential problem and to fully assess the potential of these safety-related issues. If a defect is found, the NHTSA will issue a recall.

2021 Toyota C-HR Pre-Collision System Inoperative Without Warning

Posted on by

In December 2020, Toyota began an investigation into certain 2021 Toyota C-HR crossover SUVs after receiving field reports from the Japanese market alleging that when using the Traffic Movement Notification feature (a Japanese market feature not available in the U.S.), the vehicle radar sensor did not detect a vehicle driving in front of it. An inoperative radar sensor also meant that other features, such as Pre-Collision System (PCS), Dynamic Radar Cruise Control (DRCC), and Lane Tracing Assist (LTA) could be affected. In these cases, dealer technicians observed that the beam axis for the radar sensor was out of specification and adjusted it during the inspection. After completing the adjustment and initializing the radar sensor, the vehicles were able to detect the preceding vehicle.

According to the defect report, certain 2021 Toyota C-HR vehicles are equipped with a millimeter-wave sensor (radar sensor) and a camera to detect objects in front of it. These sensors also support certain driver assistance features, including the Pre-Collision System (PCS).

Under certain circumstances, the initialization of the radar sensor may not have been completed correctly, resulting in the PCS not being able to detect an object in front of it. As a result, the vehicle will not provide warnings or braking assist, and would not display a message or indicator to the driver that PCS is not functional. An inoperative PCS, without a PCS malfunction indicator to the driver, may increase the risk of a crash in certain driving situations.

As of January 2022, Toyota has not received any U.S. field reports or warranty claims related to this condition. Based on their investigation results, however, Toyota decided to conduct a voluntary safety recall campaign. Owners of the subject vehicles will be asked to take their vehicles to their Toyota dealer to have the radar sensor inspected and properly initialize if necessary. Toyota’s number for this recall is 22TA02 and the NHTSA campaign number is 22V-107.
