General recall: The high voltage battery may have an improperly secured internal module

Recall published 3 months ago

The high voltage battery may have an improperly secured internal module component.

The hazard: Fuel leak or fire risk

The recall addresses a leak or overheating component that can ignite. Where the notice says park outside, that wording is deliberate.

What the notice says: A loose component may move and damage the high voltage battery, increasing the risk of a fire.

Why it matters: The vehicle may leak fuel, or a component may overheat enough to start a fire. Several of these campaigns involve a fire risk while the vehicle is parked and switched off, which is why the parking instructions matter.

What to do about Fuel / fire

General — The recall addresses a leak or overheating component that can ignite. Where the notice says park outside, that wording is deliberate.

  1. Read the risk note above carefully. If it says to park outdoors and away from buildings, do that tonight — the fire can start with the engine off and the key indoors.
  2. If you smell fuel, see a leak under the car or notice smoke or a burning smell, stop driving it and have it towed.
  3. Park away from the house, the garage and other vehicles until the repair is finished, and do not leave it charging unattended if it is electric.
  4. Keep the repair order the dealer hands you. It is your proof the campaign was closed out, and it matters at resale.

Getting the repair booked and paid for

The money side of a vehicle recall is simple. The scheduling side is where people lose weeks.

  • Ask whether the parts are physically in stock before you accept a date. A booking without parts is a wasted morning.
  • If the dealer says the remedy is not yet available, ask to be put on their notification list and get that in writing by email.
  • Where the manufacturer has issued an interim measure — park outside, do not drive, a software limiter — follow it until the full remedy is done.
  • Reimbursement claims for earlier out-of-pocket repairs go to the manufacturer, not the dealer, and need the original itemised invoice.
