Quick answer

For Chevrolet Bolt EV and Bolt EUV vehicles listed in the verified applicability data, U362E is addressed by Chevrolet communications that instruct technicians to use the published Service Information (SI) diagnostic/repair procedures when U362E is present with symptom 17 or 9 already set. A 2024 communication states that certain vehicles may set a false DTC, but the supplied evidence does not establish that every U362E is false.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does U362E mean?

For Chevrolet Bolt EV and Bolt EUV vehicles listed in the verified applicability data, U362E is addressed by Chevrolet communications that instruct technicians to use the published Service Information (SI) diagnostic/repair procedures when U362E is present with symptom 17 or 9 already set. A 2024 communication states that certain vehicles may set a false DTC, but the supplied evidence does not establish that every U362E is false.

2. Technical explanation

Verified Chevrolet/NHTSA manufacturer communications group U362E with U3620–U362E and U3630–U3636. The September 2024 communication states that certain listed vehicles may have a false DTC set. It specifically directs that, if U362E or the listed related codes are present with symptom 17 or 9 already set, technicians must follow the published SI diagnostic/repair procedures. Earlier April 2024 communications provide a similar SI instruction for symptom 17. The supplied evidence does not provide the underlying component-level definition of U362E or the SI repair steps.

3. What system is affected?

Not yet established by verified evidence.

4. How serious is this code?

Unknown. The supplied evidence does not assign a severity level.

5. Symptoms you may notice

  • A charging limit to 30% state of charge is mentioned in one April 2024 manufacturer communication excerpt.
  • A DIC message is mentioned in one April 2024 manufacturer communication excerpt.
  • The supplied evidence does not establish that these symptoms occur on every vehicle with U362E.

6. Possible causes

  • Certain listed vehicles may have a condition in which a false DTC is set, according to the September 2024 manufacturer communication.
  • The underlying cause of U362E is not yet established by the supplied verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence. One verified communication mentions charging limited to 30% state of charge, but does not establish charging guidance for every U362E occurrence.

9. What you can safely do

  • Arrange diagnosis by a Chevrolet dealer or qualified service provider using published Chevrolet Service Information.
  • Do not rely on the false-DTC statement as proof that the code can be ignored; the verified communication directs SI diagnosis/repair when symptom 17 or 9 is already set.
  • Avoid high-voltage system repair or diagnostic work unless performed by appropriately qualified personnel using manufacturer procedures.

10. Step-by-step troubleshooting

  1. Confirm the stored DTC and associated symptom status with appropriate Chevrolet diagnostic equipment.
  2. If U362E is present with symptom 17 or 9 already set, follow the published Chevrolet SI diagnostic/repair procedures, as directed by the September 2024 manufacturer communication.
  3. For U362E with symptom 17, earlier April 2024 communications also direct technicians to Chevrolet SI diagnostic/repair procedures.
  4. The supplied evidence does not establish additional owner-performed troubleshooting steps.

11. When to contact service

Contact a Chevrolet dealer or qualified service provider. Provide DTC U362E and ask them to review the applicable Chevrolet SI procedures and N242443490 communication context.

12. What the service center may check

  • Retrieve and document U362E and any associated symptom status.
  • Determine whether symptom 17 or 9 is already set.
  • Follow the published Chevrolet SI diagnostic/repair procedures when the specified code-and-symptom condition is present.
  • Review the applicable manufacturer communications, including N242443490.

13. Possible repair or resolution

  • The verified communications direct use of published SI diagnostic/repair procedures; they do not provide the actual repair steps in the supplied evidence.
