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.

Crankshaft Position Sensor Failure

Posted on by

Fiat Chrysler Automobiles (FCA) has recently taken action to address a potential problem that may affect certain 2014-2019 Ram 1500 trucks and 2014-2020 Jeep Grand Cherokee SUVs. The issue involves an unexpected engine stall, which could pose a safety risks to vehicle owners.

In May 2023, the FCA Technical Safety and Regulatory Compliance (TSRC) organization initiated an investigation into certain models manufactured between 2014 and 2019 for Ram 1500 trucks and between 2014 and 2020 for Jeep Grand Cherokee SUVs. The focus of the investigation was on vehicles equipped with 3.0L Diesel engines. It was discovered that these particular vehicles had a tone reluctor wheel with an insufficient bond between the magnetic coating and the tone wheel body. Upon analyzing the stall patterns and reviewing vehicle history, it was determined that the affected vehicles were those manufactured with Gen II 3.0L diesel engines, and the crankshaft tone wheel was identified as the source of the stalls.

According to the defect report, the magnetic material attached to the reluctor wheel provides a crucial signal to the crankshaft position sensor. When this signal is lost, the engine’s ability to synchronize injector pulses and cam timing is compromised. Consequently, the loss of the crankshaft position can lead to an engine stall, leaving the vehicle unable to restart.

To address this issue, FCA will be updating the powertrain control module software to ensure that vehicle propulsion is maintained even in the event of a lost crankshaft position signal. By reading the camshaft position signal, the updated software will mitigate the risk of engine stalls.

As part of the recall process, FCA has assigned the number 66A to this specific recall, while the NHTSA campaign number is 23V-411. It is important to note that this recall represents an expansion of a previous recall, namely recall 20V-475.

FCA US will be contacting vehicle owners to ensure that they are informed about the issue and the necessary steps to resolve it. The company is aware of 10 customer assistance records, 611 warranty claims, and three field reports that may be associated with this particular issue.

Volvo PHEVs Could Experience Loss Of Power And Will Not Restart

Posted on by

Some 2022-2023 Volvo PHEV vehicles could experience a loss of drive power because of a software error that may prevent the combustion engine from starting. Owner notification letters are expected to be mailed in December.

Volvo first became aware of the problem after receiving complaints of a vehicle no start condition in several Volvo models. (A low coolant flow issue was determined to be a potential cause.) Further investigation found that the estimated cooling flow on the electrical drive (ED) cooling circuit was set to zero when max cooling was requested. The problem was caused by faulty software logic. When the estimated cooling flow is set to zero the inverter generator module will set available torque to zero and the combustion engine will not start.

If the issue occurs the driver will experience a warning message in dim that “Propulsion System Service is Required“, at start. The vehicle will continue to start and drive on electric propulsion until a second warning appears – “Turtle in DIM and speed limited to 75 km/h“. If the driver ignores these visual and mechanical warnings, the vehicle will display “stop safely” and lose electric propulsion as the high voltage battery is depleted.

The vehicles affected include:

2022-2023 Volvo S60
2022-2023 Volvo S90
2022-2023 Volvo V60
2022-2023 Volvo XC60
2022-2023 Volvo XC90

The problem will be corrected through a ECM software update. Volvo’s number for this recall is R10198 and the NHTSA campaign number is 22V-793.

If your vehicle is experiencing repeated problems it could be a Lemon. Know your Lemon Law Rights. If you have any questions about your rights and the California Lemon Law, please call our office at 1-888-395-3666 and get some great Lemon Law advice!

Tesla Over-The-Air Software Update For Window Safety

Posted on by

Tesla will be performing an over-the-air (OTA) software update on certain Model 3, Model S, Model X, and Model Y vehicles because the automatic window reversal system does not meet the Federal Motor Vehicle Safety Requirements for power-operated window systems. Over one million Tesla vehicles are included in this recall.

The vehicles affected include:

2017-2022 Tesla Model 3
2021-2022 Tesla Model S
2021-2022 Tesla Model X
2020-2022 Tesla Model Y

Tesla first became aware of the problem in August 2022, during production testing. Technicians identified a window automatic reversal system that had greater than expected variations in response to pinch detection. Tesla conducted additional testing on multiple models using several window positions, multiple spring rates, and gap designations. Tesla determined that the pinch detection and retraction performance in the test results exceeded the requirements of FMVSS 118, Section 5 (automatic reversal systems). When closing, the window may exert more force than safety requirements permit before retracting. The window may also retract less than the distance required. If a window is closing and detects an obstruction, the condition may increase the risk of a pinching injury to the occupant.

Tesla will perform an over-the-air (OTA) software update of the automatic window reversal system. Notification letters are expected to be mailed on November 15, 2022. Tesla is not aware of any warranty claims, field reports, crashes, injuries, or deaths related to this condition. Tesla’s number for this recall is SB-22-00-013 and the NHTSA campaign number is 22V-702.
