What stands out
Of the 4 model years of Toyota C-HR we track for powertrain problems, this one has the fewest owner complaints on file (13).
The failure pattern owners describe
Buyer takeaway: The 2021 Toyota C-HR has multiple documented transmission failures occurring between 40k and 68k miles—sometimes with zero warning despite regular dealer maintenance—with replacement costs running $11k to $13k. Toyota has acknowledged the issue exists but refuses to recall 2021 models, despite having issued recalls for 2018 and 2019 models with the same problem.
Transmission failures in the 2021 C-HR cluster around 60,000 miles, though one owner reported failure at 40,000 miles and another at 67,764 miles. The failures happen even on vehicles with full dealer maintenance records and no abuse history.
Symptoms vary: some transmissions quit shifting entirely and cap speed at 25 mph; others produce whirring or whistling noises before complete failure. A couple of owners had no warning signs whatsoever before the transmission became inoperable.
Dealers confirm transmission malfunction but refuse warranty extensions. Owners cite replacement costs of $11,000 to $13,000. One mechanic told an owner this is a "known issue" Toyota is aware of. Multiple owners reference that Toyota issued recalls for 2018 and 2019 C-HR models with identical transmission problems but has not recalled the 2021 model despite the failure pattern being essentially identical. One owner notes Toyota Canada has acknowledged the problem. The consensus among owners: Toyota continued manufacturing and selling 2021 models after learning about the transmission defect from earlier model years.
