All VINs under ZKH are expired as of July 6, 2025 Toyota has received reports stating that the door mirror foot lights (puddle lights) may project a distorted image of the C-HR logo onto the ground. This distortion may be due to the projector film in the door mirror foot light becoming damaged due to heat and moisture. Although the door mirror foot light is covered by Toyota’s New Vehicle Limited Warranty for 3 years or 36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is providing coverage for repairs related to the condition described above.

The failure pattern owners describe
Electrical failures are hitting this model across multiple systems. Battery problems start early—owners report needing jump-starts or replacements at 18,000 to 39,000 miles. Dashboard lights flicker randomly, odometer display switches between modes unexpectedly, and clocks show garbled characters; dealerships dismiss these as normal LED behavior or heat sensitivity, but owners say this never happened before.
Electronic parking brake malfunctions trap the brake in the engaged position, blocking rear-brake service and triggering warning messages. Steering loses power mid-drive with "abnormal voltage" alerts, then the car stops completely. Engine cuts off while driving—some right after purchase, others repeatedly—with fuse-blowing patterns suggesting deeper wiring issues. One owner needed a fuse replaced constantly; another couldn't drive past 5–10 miles before losing power again.
Climate control stops working due to ECM communication failure, with dealers quoting $1,500 out-of-pocket at 30,000 miles. Fuel gauges fail silently. Front sensor errors pop up especially in rain. Cruise control drops out without warning while all dashboard lights flash. Some owners report calling Toyota multiple times over weeks with no callback. One had soy-based wiring insulation attracting rodents, costing $4,700 in damage repairs.
Failure modes owners describe
Battery and alternator charging system failure
Battery drains rapidly or fails prematurely, requiring jump-starts or replacement as early as 18,000 miles. Some owners report parasitic drain and fob batteries showing erratic charge levels. One owner replaced battery but issues persisted; another had to jump-start every time after initial jump attempt.
When: 18,000 miles; approximately 39,000 miles
Symptoms owners cite: Car won't start; Battery dies within hours of jump-start; Dashboard odometer and clock display errors; Fob battery showing fluctuating charge readings

When: 9,307 miles
Symptoms owners cite: Cruise control deactivates unexpectedly; All warning indicators illuminate simultaneously; Master warning indicator flashing; Indicators flicker erratically
Repairs/costs cited: Towed to dealership; failure could not be duplicated and no repair performed
Recalls/TSBs owners mention: Manufacturer contacted twice; case numbers 1904052602, 1810091666
Engine stalling and power loss during driving
Engine cuts off unexpectedly while driving at various speeds, forcing vehicle to coast to roadside. Occurs repeatedly and without warning. One case involved complete stalling the day after purchase (before 35 miles driven). Another owner reports needing fuse replacement repeatedly but problem recurs within 5–10 miles.
When: 9 miles; 13,000 miles; variable
Symptoms owners cite: Engine cuts off while driving; Vehicle coasts to stop; Loss of power during acceleration; Repeated stalling after fuse replacement
Codes mentioned: Drive-Start Control Malfunction, Brake Override Malfunction
