NHTSA Complaint #11506915 — 2017 BUICK ENCLAVE

The battery, which is housed within the passenger compartment, began emitting fumes that caused passengers to experience physical symptoms of nausea and headache, followed by smoke and extreme heat. We realized what was going on and turned off the engine before it caught fire, but there were no warning lights on the dash and no messages from the vehicle itself. Initially we thought it was a smell outside of the vehicle. Even the vehicle app diagnostics don't report any kind of an issue.
