Honda CR-V Hybrid and 2020-2021 Honda Insight
- 27,838 vehicles are affected in the United States
- Hybrid PCU software will be updated, for free
- No reported crashes or injuries related to this issue
TORRANCE, Calif. – Dec. 22, 2020 – Honda will voluntarily recall 27,838 model-year
2020 Accord Hybrid, 2020 CR-V Hybrid and 2020-2021 Insight vehicles in the United States to update software in the Hybrid Power Control Unit (PCU). Under certain circumstances, the portion of the PCU that controls charging of the 12 volt accessory battery may malfunction, sending the PCU into a “fail safe” mode, preventing battery charging and activating warning displays for the driver. Since a charged 12 volt battery is required for proper vehicle function, this condition may cause a vehicle to stall while driving, potentially increasing the risk of a crash. Honda has received no reports of crashes or injuries related to this issue.
Honda is announcing this recall to encourage each owner of an affected vehicle to take it to an authorized dealer as soon as they receive notification of this recall from Honda. Mailed notification to owners will begin in late-Feb. 2021. Owners can also
determine if their specific vehicles are included in the recall by visiting www.recalls.honda.com or by calling (888) 234-2138.

Total number of potentially affected vehicles: 27,838
Percentage of affected vehicles that contain the defect: 2%
Defect description:
The DC-DC converter on certain PCUs contain transistors with a high concentration of dopant injections. The increased doping, along with cold ambient temperatures, could amplify the voltage output and shut down the DC-DC converter due to overvoltage, which prevents the 12volt battery from recharging. If vehicle operation continues after illumination of the 12-volt battery system charging indicator, a depleted 12-volt battery can restrict or eliminate motive power, increasing the risk of a crash.
Chronology:
November 2019 to March 2020
Honda launched investigations in the U.S. and several global markets that received reports of
DC-DC converter failure. The supplier’s assembly processes were evaluated, and Honda found that there were no specifications for the application of dopant injections to the transistors on the DC-DC converter. The supplier began monitoring for high concentrations of dopant injections in the transistors, which Honda identified to be the cause of the increased voltage in the DC-DC converter in low ambient temperatures. The increased voltage inadvertently activated a test circuit only used during vehicle manufacturing, which amplified the DC-DC converter voltage output. Voltage output above the system’s threshold could result in overvoltage and shut down the DC-DC converter.
July to November 2020
Honda examined the multitude of scenarios potentially occurring due to DC-DC converter failure and the inability to recharge the 12-volt battery. The failure mode was also confirmed during recreation testing in different hybrid electric vehicle models installed with the same PCU and DCDC converter.
December 10, 2020
Honda determined that a defect related to motor vehicle safety existed and decided to conduct a safety recall.
As of December 10, 2020, Honda has received 53 warranty claims, 65 field reports, and no reports of crashes or injuries related to this issue.
Program for remedying the defect:
Registered owners of all affected vehicles will be contacted by mail and asked to take their vehicle to an authorized Honda dealer. The dealer will update the PCU software program for free. Owners who have paid to have these repairs completed at their own expense will be eligible for reimbursement, in accord with the recall reimbursement plan on file with NHTSA. 573.6(c)(8)(ii)
The estimated date to start notification to dealers: December 18, 2020
The estimated date to start notifications to owners: February 25, 2021
Representative copies of all notices, bulletins and other communications:
A copy of the dealer service bulletin, the final customer notification letter, and other dealer communications will be submitted to your office as soon as possible.
A draft of the owner notification letter will be submitted to your office as soon as possible.

("Honda") offers the i-HDS (Honda Diagnostic System) software suite for the diagnosis and repair of electronic systems on Honda and Acura automobiles, and for the reprogramming of electronic control units (including, but not limited to, ECMs and PCMs). This software provides access to all Honda and Acura vehicle systems (access to the immobilizer security system requires a Security Professional level software subscription and Vehicle Security Professional [VSP] registration with NASTF). To use the i-HDS software, you need to purchase one of our convenient subscription options. In addition, you will need a pass-thru Vehicle Communication Device (VCI) that is compliant with SAE J2534-1 and J2534-2 in order to communicate with the vehicle
Vehicle Communication Interfaces (VCI)
The i-HDS software supports the use of a generic pass-thru VCI that is compliant with SAE J2534-1 and J2534-2. However, Honda recommends the Denso DST-i or the Bosch MVCI for use on Honda and Acura vehicles, as Honda has worked closely with these manufacturers to ensure their hardware and our software interact safely and within the J2534-1 and -2 specifications, for both diagnostics and reprogramming. If you choose to use a generic VCI, please carefully consider the customer and technical support options you will receive from your chosen device supplier. Honda does not provide technical or customer support for generic VCI devices.
The VCI Application Table below lists devices that either are approved and supported by Honda or are known to have completed and passed an independent, exhaustive validation program with our i-HDS software suite.

Reprogramming with the J2534 Rewrite Application in i-HDS
Included in the i-HDS software suite is a new reprogramming application called J2534 Rewrite. This application is made available to all subscribers of the i-HDS software suite and replaces the previous generation software, J2534 Honda Pass-thru Reprogramming Software.
This new application is compatible with generic VCIs that comply with SAE J2534. It must be used to reprogram any Honda/Acura vehicle equipped with ECUs that support reprogramming. Refer to the table below for legacy applicability for the programming of ECMs and PCMs. Though system dependent, late-model vehicles may be equipped with other ECUs that support reprogramming as well, e.g. ABS or VSA. J2534 Rewrite must be used to reprogram these control modules, as instructed in an applicable service bulletin.
As shown in this table, not all legacy Honda/Acura models are equipped with a reprogrammable ECM/PCM. Furthermore, all 2007 and later models not listed in the table are fully supported with this application.
