In December 2020, just before a Quebec winter, Amélie Paquette purchased her 2021 Tesla Model 3. She spent $52,880 on it, which is a significant choice for anyone. Sensors started to malfunction within weeks. Debris found its way into the fan mechanism in a matter of months. Eventually, it became necessary to replace the manifold, compressor, and fluid lines—at least under warranty. Then, on January 27, 2026, while the cabin was being preheated, smoke began to pour out, followed by a chemical odor. The heat pump as a whole had to be removed. The warranty had run out this time. When she formally objected, Tesla sent her an email rejecting her demand letter and handed her a bill for $4,476.55.
That email might turn out to be one of Tesla’s more costly choices in Canada.
On May 13, 2026, Paquette’s attorneys at Perrier Avocats filed a class action request in Quebec’s Superior Court, attempting to represent all Quebecers who own or rent a Tesla with a heat pump, including the Model S, Model 3, Model X, Model Y, and Cybertruck. Over 55,000 Tesla owners in the province could be affected by the $400 million in potential damages. Some of the most consumer-friendly laws in North America are found in Quebec, and the filing characterizes this as a “hidden defect.”
The legal argument is based on a particular but important premise: Tesla is legally presumed to have known about the heat pump’s flaws as a professional seller and ought to have disclosed them prior to the sale. A car in this price range should reasonably last ten years or 200,000 kilometers before needing a major repair, according to Quebec’s Civil Code and Consumer Protection Act. At 158,220 kilometers, Paquette’s vehicle experienced a significant breakdown. The case revolves around that gap, which is approximately 42,000 kilometers short of the benchmark.
The fact that the heat pump issues are not novel or mysterious makes it more difficult for Tesla to ignore them. In January 2021, reports of Model 3 and Model Y heating problems began to surface. By early 2022, owners in cold climates were completely losing cabin heat when the temperature fell below -10°C. After determining that the problem could impair windshield defrost performance, the National Highway Traffic Safety Administration eventually issued a recall covering specific 2021 and 2022 vehicles. Transport Canada launched its own inquiry. At the time, Elon Musk acknowledged the issue and suggested that a software update might help. However, many owners found this claim unsatisfactory because the failures frequently seemed to be mechanical.
There’s a sense, watching this case unfold, that the lawsuit was probably inevitable. Tesla’s heat pump is integrated deeply into the vehicle’s battery thermal management system, which means repairs are expensive and options outside the Tesla service network are limited. In a place like Quebec, where January temperatures can fall to -25°C or lower, losing cabin heat is not an inconvenience. It is a safety issue. When regulators and courts in the same province have already authorized class actions over paint peeling and unexpected connectivity fees, adding a heating system failure to that list does not feel like a stretch.
This is Tesla’s fourth class action in Quebec alone. The company is also facing up to $14.5 billion in legal liabilities across multiple jurisdictions. It’s unclear if the courts will approve this specific case because class actions in Quebec must first pass a certification process. However, given the size of the impacted class and the robustness of the province’s consumer protection laws, it might be one of Tesla’s more significant legal challenges in Canada if it is approved.
Paquette’s case started with a $4,477 repair bill and an unresponsive company. How far the courts will go with it is still unknown. However, thousands of Tesla owners in Quebec claim they immediately recognize the story she is telling—one of repeated failures, delayed diagnoses, and a manufacturer that stopped helping precisely when the costs got serious.
