2018 Chevrolet Bolt EV

On October 3, 2024, the Office of Defects Investigations (ODI) opened PE24028 to investigate alleged failures of Enel X Way's JuiceBox Level 2 residential EV chargers. The allegations were described as thermal incidents and electrical malfunctions, which could trip the circuit breakers in Juicebox owners’ homes and disrupt electric vehicle charge cycles. On October 2, 2024, Enel X Way posted on its website that Enel X Way North America would cease operations in the United States and Canada on October 11, 2024. The closure would potentially impact the charging app and supporting software. ODI sent Enel X Way an Information Request (IR) letter on October 21, 2024. Enel X Way provided an incomplete response to the IR on December 9, 2024. Enel X Way later provided a complete response to the IR on January 24, 2025. ODI reviewed Enel X Way’s IR submissions to determine whether further action is required. Based on ODI’s analysis, there was no clear trend in the cause of the failures described in customer complaints and warranty reports. Additionally, there have been no recent reports alleging safety issues. The available information does not warrant further action at this time. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor for any safety trends and reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in this Closing Resume, go to NHTSA.gov.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

In October 2020, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE) on 2017-2020 Model Year (MY) Chevrolet Bolt vehicles based on complaints received alleging that the vehicles caught fire under the seating area while parked and unattended. At the time, ODI had received 2 Vehicle Owner Questionnaires (VOQs) and several field reports. All complaints alleged vehicles caught fire during or after electrical charging.ODI's review found vehicle thermal events occurred during and/or at the end of the battery module charging cycle. The information learned from NHTSA and General Motors joint vehicle inspections prompted General Motors to file Recall 20V-701 on April 29, 2021. The remedy for this recall included 1) performing diagnostic procedures to identify and replace potentially defective battery cell-module assemblies and 2) installing onboard diagnostic software, designed to detect and warn owners regarding potential issues related to changes in battery module performance over time. Until this interim remedy became available for all affected vehicles, General Motors instructed their customers to enable ?Hilltop Reserve or ?Target Charge Level, based on the vehicle-equipped technology. Enabling these technologies would limit charging capacity of the battery module to a maximum of 90 percent. General Motors then continued to investigate the root cause of these battery cell module thermal events, which would lead them to their long-term recall remedy solution. Utilizing the information obtained from the Recall 20V-701 software update, General Motors and LG Energy Solutions,the supplier of the battery cell module pack along with LG Electronics,determined the root cause of the thermal events to be the result of two simultaneous manufacturing defects occurring in the same battery cell. The defect condition appears to be aggravated by routinely charging the battery to a full or nearly full state of charge after it has been substantially depleted. The two defects, located within the same battery cell module, would cause an internal short within the battery pack, resulting in the thermal events. The manufacturing process was changed to prevent the occurrence of these two defect conditions.On July 24, 2021, General Motors filed a defect information report recalling all 2017-2018 Chevrolet Bolt and certain 2019 Chevrolet Bolt vehicles with design level N2.1 battery cell produced at the LG Ochang, Korea plant. This remedy replaces defective battery cell-modules and will prevent potential thermal events from occurring during and/or at the end of the charge cycle. The recall (21V-560) includes vehicles that were remedied under 20V-701.General Motors continued to review new data after Recall 21V-560 and learned of an incident that occurred outside of the scope of the recall population. Additional analysis led General Motors and LGES to determine that the manufacturing defects defined by Recall 21V-560 were not isolated to one battery manufacturing plant. On August 21, 2021, General Motors filed a defect information report to expand the scope of recall 21V-560. The recall (21V-650) includes all 2019-2022 Chevrolet Bolt EV and 2022 Chevrolet Bolt EUV vehicles. In view of the recall actions being taken by General Motors, ODI is closing this Preliminary Evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances.The ODI reports cited above can be reviewed online at nhtsa.gov under the following identification numbers:11230072, 11425524, 11339878, 11365622, 11364692, 11427180, 11429891, 11374956, 11407212, 11372429, 11425225, 11415800

Power steering assist cut out while driving and traction controllight came on. There is now no steering assist. The car is with the dealer shop and their diagnostics indicate the the steering column needs to be replaced. Dealer shop now says the steering column is on EXTREME backorder with no time estimate of availability. The car is almost impossible to steer at low speeds.The power steering rack and pinnion assembly was replaced back in August of 2023 due to the rack binding, so that part is realatively new.

Steering randomly will fail to return to center in turns, causing the driver to have to manually turn wheel back to center. Happens in both sharp and sweeping turns in both the left and right direction while accelerating, decelerating, and maintaining speed. Issue occurs several times a week. I nearly hit an oncoming car head-on in a very gentle sweeping left hand turn on May 10th when my Bolt continued turning left rather than re-center when I stopped giving it left steering input. I was going about 35 and decelerating gently for a stop sign at a T intersection at the bottom of a mild downhill slope of 5 to 10 degrees. The car I nearly hit was approaching in the opposite lane on the inside of the curve. When the left hand curve straightened out, my steering wheel (and wheels) did not return to center. My car continued across the yellow double lines. I had to quickly jerk the wheel to the right to avoid a collision. *I had to physically return the wheel to center through manual input to get my car to drive in a straight line.* I narrowly avoided a head-on collision. There was no advance warning. Having the steering randomly behave unexpectedly and in direct opposition of the vehicle's design, and *every* other vehicle's design is very dangerous. This is a known issue across many, many Bolts. Replacing the steering rack/column for this known safety issue on all generations of the Chevrolet Bolt is an expensive repair. Please investigate and issue a safety recall and force GM to correct this known safety defect that they should have already voluntarily recalled.

The steering wheel gets stuck, is difficult to turn, and doesn't return to center. Issues with this make the car much more difficult to drive and makes it impossible to sense the state of the road with the steering wheel. This can lead to loss of control. No warning lamps or messages informed me of this issue.
