Nissan Leaf EV Unintended Acceleration

Posted on by

Nissan North America, Inc. (Nissan) is taking action to address a safety matter related to certain 2018-2023 LEAF EVs. These Electric Vehicles could experience unintended acceleration. This issue came to Nissan’s attention during internal testing in December 2021 when a trial vehicle showed a motor torque deceleration delay following the deactivation of Intelligent Cruise Control.

To tackle this problem, Nissan conducted computer simulations, analyzing data from the test vehicle, in an effort to replicate the condition. After several tests, they identified a specific sequence of actions that could potentially lead to the reported phenomenon, although they were unable to recreate the issue on an actual vehicle.

To ensure the safety of their customers, Nissan continued their efforts to replicate the phenomenon under real-world conditions. After extensive computer simulation and on-track testing, they determined that the following sequence of actions must be completed in under eight (8) seconds for the unintended acceleration to occur:

1. Disengage Cruise Control, Intelligent Cruise Control, or ProPILOT Assist.
2. Immediately after disengagement, shift drive modes from ‘D’ to ‘B’ or ‘ECO’, or activate e-Pedal ‘ON’.
3. Press the accelerator pedal and then release it.

Nissan’s evaluation of the risk associated with this issue in real-world driving conditions is very low, as it has not occurred outside of controlled track or simulated test environments. However, taking a cautious approach, Nissan decided to conduct a recall campaign to reprogram the Vehicle Control Module (VCM) as a preventive measure.
For clarification, the ‘B’ mode engages the regenerative braking system more aggressively on downhill slopes, reducing the need for excessive brake use. This mode is manually selected by shifting from ‘D’ to ‘B’ using the shift lever.

To address the issue, Nissan dealers will reprogram the Vehicle Control Module (VCM). You can refer to Nissan’s recall number for this action, which is R23A6, and the corresponding NHTSA campaign number, which is 23V-494.

Ford Escape, Ford Maverick And Lincoln Corsair Engine Failure

Posted on by

Ford Motor Company (Ford) has recently announced a crucial safety recall for specific models of Ford Escape, Ford Maverick, and Lincoln Corsair vehicles. The recall aims to address a potential issue that could lead to a vehicle fire, urging affected owners to promptly visit their dealers for necessary repairs and precautions.

The vehicles affected by this recall include those equipped with 2.5L HEV/PHEV engines, manufactured during the specified time frames. The identified problem revolves around the premature failure of these engines, which can have severe consequences. When an engine fails, there is a risk of significant quantities of engine oil and/or fuel vapor being released under the vehicle’s hood. These substances may then migrate to and accumulate near potential ignition sources, posing a potential fire hazard. In addition to the risk of fire, localized melting of components or the emission of smoke may also occur.

The specific models affected by this recall are the 2020-2023 Ford Escape, the 2022-2023 Ford Maverick, and the 2021-2023 Lincoln Corsair. Ford has identified isolated engine manufacturing issues as the root cause of the 2.5L HEV/PHEV engine failures that result in engine block or oil pan breaches. Despite the breach, the HEV/PHEV system continues to propel the vehicle, allowing the driver to continue operating it. Unfortunately, this means that as the driver continues to drive after a block breach, oil and/or fuel vapor continues to be expelled and accumulate near ignition sources, exacerbating the risk.

Owners of the affected vehicles should be aware of the signs indicating engine failure. These signs include loud noises such as a metal-to-metal clank, which will be audible to the vehicle’s occupants. Additionally, an engine failure will lead to a reduction in engine torque. If drivers notice any unexpected engine noises, experience an unexpected torque reduction, or observe smoke emanating from the engine compartment, they are strongly advised to safely park the vehicle and promptly shut off the engine.

Ford is actively working on developing the remedy for this issue. In the meantime, interim letters have been sent out to notify owners of the safety risk. These letters were mailed on June 23, 2023, to inform owners about the importance of addressing the issue. Once the remedy is available, a second round of letters will be sent out to inform owners and provide instructions for getting the necessary repairs. It’s important to note that this recall, identified by Ford as recall number 23S27, expands and replaces the previous recall number 22V-484. Therefore, even if the vehicles have been previously repaired under recall number 22V-484, owners will still need to have the new remedy completed to ensure their safety.

Chevy Express & GMC Savana HVAC Circuit May Overheat

Posted on by

General Motors (GM) is one of the largest automobile manufacturers in the world, with a reputation for producing reliable and safe vehicles. However, like all automakers, GM occasionally identifies issues with its vehicles that need to be addressed to ensure the safety of its customers. Recently, GM identified a problem in certain 2003-2023 Chevrolet Express Cutaway and 2003-2023 GMC Savana Cutaway incomplete vehicles. These vehicles are equipped with wiring for an optional rear heating, ventilation, and air-conditioning (HVAC) system.

According to the defect report, these vehicles are equipped with an unused circuit that a final-stage manufacturer may elect to use to install an optional rear HVAC system. While this circuit is not typically used, if the final-stage manufacturer leaves the circuit’s connectors or cut wires unsealed, where exposure to moisture or contamination may, over time, cause corrosion. In rare cases, this corrosion could result in a high current draw through the circuit at the vehicles’ lower left side B-pillar. If left unaddressed, the problem could cause excessive heat in the circuit that could result in a fire.

To address this problem, GM began a product investigation in December 2022, after receiving reports of two alleged fire incidents involving a 2013 and a 2014 Chevrolet Express Cutaway incomplete vehicles. The company’s investigators analyzed inspection reports from the two subject vehicles and retrieved and analyzed field data for all Express Cutaway and GMC Savana Cutaway vehicles sold for model years 2005 through 2023, comprising approximately 167,000 units. Analysis of the field data, including legal claims, identified a total of eight potentially related complaints, six of which alleged fires.

On March 30, 2023, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall. While the company is not aware of any accidents or injuries associated with this condition, it is taking this action to ensure the safety of its customers.

Owners of the affected vehicles will receive notices with instructions to return to their dealers to have the rear HVAC blower motor circuits at the left side B-pillar properly sealed. The recall is identified by GMC’s number N222386050 and the NHTSA campaign number is 23V-247.

2023 Genesis G90 Abnormal Pretensioner Deployment

Posted on by

Hyundai Motor America (Hyundai) will be contacting the owners of certain 2023 Genesis G90 luxury sedans because of a defect affecting the seat belt pretensioners in their vehicles. The problem could result in an increased chance of injury to vehicle occupants.

In October 2022, Hyundai received information pertaining to an investigation into allegations of abnormal seat belt pretensioner deployments in vehicles associated with recalls 21V-796, 22V-069, 22V-123, 22V-218, 22V-354, and 22V-458. Recall 22V-816 was initiated as Hyundai continued to evaluate vehicles equipped with the same Samsong pretensioners that had not yet been recalled..

In January, during the continued analysis of the airbag control unit (ACU) crash pulse data recovered from a North Carolina incident, they found that the micro gas generator (MGG) separated despite having a lower pretensioner “time-to-fire”. This was the problem that was previously thought to be the contributor to over-pressurization of the pretensioner pipe. Because of this information, the North America Safety Office (NASO) decided to conduct a safety recall 012G (23V-094) of Genesis G80, GV60, GV70, and GV80 vehicles equipped with pretensioners without a vent valve. Recall 012G (23V-094) supersedes Recall 009G, obsoleting all affected population(s) of Recall 211/009G (21V-796).

In March, during the review of details surrounding Hyundai’s assessment of the open investigation into the recent recalls, Hyundai noted that the recent recalls address all U.S. vehicles equipped with the subject Samsong seat belt pretensioner excluding Genesis G90 vehicles. The G90 contains the same seat belt pretensioners but because it is installed facing outward and away from occupants, fragments entering the cabin area and injuring occupants are significantly less likely to happen. Based on this information, the NASO decided to conduct a safety recall (013G) of Genesis G90 vehicles equipped with pretensioners without a vent valve. NHTSA campaign number 23V-210.

According to the defect report, the subject vehicles are equipped with frontal/rear pyrotechnic-type seat belt pretensioners that could deploy abnormally in certain crash conditions. The problem is due to the over-pressurization of the pretensioner pipe. Depending on specific vehicle characteristics such as pretensioner load limiter specification, the airbag control unit logic, crash duration/severity, and micro-gas generator orientation, occupants could experience an increased risk of injury.

Owners of the affected vehicles will be notified with instructions to bring their vehicles to a Hyundai dealer to have the seat belt pretensioner’s micro gas generator and delivery pipe secured with a cap to prevent potential abnormal deployment.
