Over the past several weeks, I have had the car issue an error stating "Shift to Park". I have previously had the car in for service for this error, and in the past have succeeded in getting it to stop by squeezing the trigger on the shifter repeatedly, but the error has returned and is getting more persistent. It now happens every few times I park the car. I cannot turn off the car without getting the error message to clear, and sometimes it has taken considerable time and effort to get the message to clear. I have not taken the car back to the dealer again as I read that it was important to first submit a report here.

The shift to park error populates every time I park incorrectly informing me to shift to park before turning off vehicle and thus preventing me from turning off the vehicle. I have to restart the car, put in drive and put back in park forcefully and it may recognize the shift from drive to park.

Going 80 mph on the freeway with adaptive crusie control on, the car begins to jerk, and the rpm's shoot up and down. The adaptive cruise control disengages, the stabiltrack, abs, and engine light turned on and the car goes into limp mode. As I slow down, the speedometer keeps increasing up to 90. After, I inspected the driver wheel speed sensor and discovered that the sensor tip in the hub had been damaged. The anti-click washer had broken and began cutting the sensor until it failed.

For a few weeks, I had been getting a "Shift To Park" messaged when I tried to power off my car after putting it into park. Like others, I was able to jiggle the shifter and press down hard to get it to recognize it was in park. Last week while I was driving at about 50 mph, the "Action Required: Shift to Park" message appeared and my check engine light turned on. The car stopped responding to acceleration so I immediately pulled off the road. I couldn't turn the car off, I couldn't drive the car, so I was stuck on the side of the parkway. After about 10 times of moving the shifter through all the gears and pressing the power button, the car finally turned off but then I had to get towed. I am lucky that I was driving in the right lane and was able to pull of immediately or otherwise I would've been stuck in traffic with cars coming by at 50 mph. It has been almost a week and the dealer still has not given me any information as to the repair of this problem.

Vehicle displays "shift to park" when it is already in park, and will not shut off. I had to leave it on, and despite nothing apparently on (electric vehicle, no motor running), it drained the12 volt battery and would not start up the next day.

"Shift to Park" error message on dashboard this error prevents the car from being driven
General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Consequence & remedy
Consequence: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
Remedy: GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 18315.
General Motors LLC (GM) is recalling certain 2018-2019 Chevrolet Equinox, Impala, Cruze, Volt and Bolt EV vehicles, GMC Terrain vehicles, Buick Lacrosse and Regal vehicles, Cadillac XTS and XTS Professional vehicles and 2018 Chevrolet Malibu vehicles. The rear brake caliper pistons may have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.
Consequence & remedy
Consequence: A reduction of braking performance can increase the risk of a crash.
Remedy: GM will notify owners, and dealers will bleed the vehicle's brake system, free of charge. The recall began October 11, 2018. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.

PE23022 · Loss Of Motive Power Due To The Battery Energy Control Module
Opened Nov 29, 2023 · Closed Mar 3, 2025
Status: closed (inferred from source dates) · Electrical System; Electrical System:propulsion System; Electrical System:propulsion System:traction Battery:management System/energy Control Module (bms/becm)
On November 29, 2023, the Office of Defects Investigations (ODI) opened PE23022 to investigate allegations of a loss of motive power, including a stall, reduced power state, and/or a no start condition due to the Battery Energy Control Module (BECM) in model year (MY) 2016-2019 Chevrolet Volt passenger car vehicles manufactured by General Motors (GM). The BECM is located within the high voltage electric vehicle (EV) battery pack and monitors the temperature, current, and voltage of the high voltage battery cell groups. GM stated that the root cause was identified as an internal failure leading to a loss of communication within the BECM and does not pose a risk to motor vehicle safety. GM further stated that the failure cannot result in a complete stall, only a reduced power mode, no start condition, or a no charge condition. GM additionally stated that if these conditions occur, the driver will be warned via a Malfunction Indicator Lamp (MIL) and/or a reduced-propulsion message in the Driver Information Center (DIC). Data received and analyzed by ODI from all sources indicates that nearly all related BECM failures caused conditions aligning with GM’s predicted outcomes. Despite the large number of warranty claims, nearly all failures were not safety-related, i.e., not a stall or reduced power mode. ODI isaware of a single minor crash and no injuries or deaths. In March 2024, GM issued Special Coverage N232432680, which was mailed to consumers, addressing BECM failures in certain MY 2016-2018 Chevrolet Volt vehicles. This special coverage provides an extension of the warranty coverage for the BECM from 8 years / 100,000 miles to 15 years / 150,000 miles for all 2016-2018 Chevrolet Volts. Additionally, GM stated that replacement components are sourced from a different supplier and not susceptible to the failure. In view of the Special Coverage issued by GM, the existing warranty coverage already in place, and the low number of safety-related occurrences, ODI is closing this Preliminary Evaluation (PE). The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, 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.
