Recalls

Good news: Recall repairs are almost always free. Book with any manufacturer dealer and quote the recall number. Transport Canada’s own wording is that a manufacturer “will almost always make these repairs free of charge”, so being asked to pay for recall work is unusual and worth questioning. Since 2018 the Minister of Transport can order a company to pay for repairs so owners do not bear the cost.

What is wrong

On certain vehicles equipped with the Active Curve System (ACS), the oil in the ACS’s reservoir could start foaming under certain dynamic driving situations in combination with an oil level below minimum. The oil foam could leak out of the oil reservoir through the vent holes in the sealing cap and spray onto hot surface components of the exhaust system. This could increase the risk of fire causing injury and/or damage to property.

What the dealer will do

Dealers will inspect the ACS reservoir for proper oil level and replace the sealing cap with an updated part.

Source: Transport Canada — Vehicle Recalls Database; NRCan — Fuel consumption ratings. Data current as of 6 August 2026. Running cost uses Ontario average prices (155 ¢/L, 14.5 ¢/kWh), which are hand-maintained estimates. These are average residential rates. A car’s charging is added on top of what your home already uses, so on a tiered, time-of-use or subsidised tariff it is billed at your top rate rather than this average — which makes the real cost higher, especially in the territories.
