Owning an electric vehicle outside its warranty period can become an expensive experience, but one Canadian Tesla owner couldn’t believe the timing of their recent breakdown. Their 2018 Tesla Model 3 AWD became completely undrivable on the exact day its battery warranty expired, leaving them facing a repair estimate of nearly $4,000.
Even more frustrating, the owner lives approximately two hours away from the nearest Tesla service center, making an already stressful situation considerably more complicated. After sharing their experience on Reddit, other Tesla owners began describing similar failures, including one who recently paid $2,100 to have a faulty heater replaced.
The unusual situation was shared on the r/teslacanada subreddit by u/countertopopular, who explained that their Model 3 had been operating normally earlier that morning. They had driven to the post office, grabbed a coffee, and were heading home when the vehicle suddenly began displaying warnings that it might not restart.
Fortunately, the owner managed to reach their driveway before the Tesla became completely inoperable, refusing to shift into gear when they attempted to drive it again. The timing was particularly unfortunate because the owner said it was the very day their eight-year battery warranty expired, although the failure hasn’t been attributed to the high-voltage battery itself.

Initially, the owner attempted to resolve the problem by purchasing a replacement 12-volt battery, hoping that it would clear the vehicle’s warning messages. Unfortunately, the replacement didn’t fix anything, leaving them arranging a two-hour tow to the nearest Tesla service center while investigating other possible causes.
Things became even more concerning when the owner received an online repair estimate totaling $3,825.98, covering a PTC heater replacement, air-conditioning recharge, and work involving the vehicle’s SuperBottle assembly. According to a later comment, the PTC heater replacement alone was expected to cost approximately $1,350 installed, although the final repair bill hasn’t been confirmed.
The owner subsequently indicated that the PTC heater appeared to be responsible for the failure, along with additional components requiring attention. While the breakdown happened on the same day the battery warranty expired, Tesla’s battery and drive unit warranty is separate from its basic vehicle warranty, meaning the coincidence doesn’t establish that the heater repair would otherwise have been covered.
Comments and Reactions to the Tesla Model 3’s Expensive Breakdown
Reddit users quickly began sharing their own experiences with similar Tesla problems, including one commenter who said their 2020 Model 3 had recently suffered a faulty PTC heater with approximately 95,000 kilometers on the odometer. The owner explained that Tesla replaced the component over the course of several days, leaving them with a $2,100 repair bill and questioning whether the problem warranted a recall.
Another commenter who identified themselves as a Tesla employee suggested that an electrical isolation fault involving the PTC heater could explain why the vehicle stopped operating, particularly if the high-voltage system stopped supporting the 12-volt battery. The original poster responded that the explanation appeared to match their situation, confirming that a PTC heater replacement was among the repairs being arranged.
Other participants questioned whether replacing the entire SuperBottle assembly was necessary, with one commenter suggesting that certain components could potentially be repaired individually for significantly less money. However, without a completed diagnosis or final invoice, it’s unclear which repairs were essential, leaving the owner facing an expensive reminder of how quickly an otherwise ordinary drive can turn into a major repair nightmare.
