A12/01049/20Safety recallInjuriesno date · EU Safety Gate

Specific transistors in the boost converter of the Intelligent Power Module (IPM) can be damaged by the high thermal stress caused by repeated driving under certain high-load driving patterns (e.g. from a stop, applying nearly full throttle and then gradually further accelerating to full throttle). This may cause the hybrid system to be shut down without entering a failsafe mode. As a result the vehicle may lose motive power while driving at higher speeds, increasing the risk of an accident.

Remedy: Type of economic operator taking notified measure(s): Importer Category of measure(s): Recall of the product from end users Date of entry into force: Unknown

The authority's notice

A12/1327/18Safety recallFireno date · EU Safety Gate

The engine wire harness has a cover attached where it is connected to the hybrid vehicle Power Control Unit. Due to assembly variation, a portion of the wire harness could contact the cover. If dust has accumulated on the wire harness or the cover, vibration during vehicle use may cause the insulation on the wires to wear over time and expose the core wire, causing an electrical short circuit to occur between the damaged wires and generate heat. If sufficient heat is generated, there is an increased risk of fire.

Remedy: Type of economic operator taking notified measure(s): Importer Category of measure(s): Recall of the product from end users Date of entry into force: Unknown

Common questions

About this generation

Which years does this page cover?

2016–2019. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.

Does the fault apply to every car like this?

No. It depends on the engine and the transmission too.

Is it free?

The fault list is.

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
