On the 2018-2019 Toyota C-HR 2.0L I4, distinct from the CVT's normal 'rubber-band' feel, owners report an internal CVT carrier/variator bearing wearing out and producing a loud humming, whining, or grinding that rises with speed (often initially mistaken for a wheel bearing) and can escalate to a jet-engine-like roar. Toyota Canada publicly acknowledged the faulty CVT bearing on 2018-2019 C-HR and extended the warranty to 10 years/193,000 km; Toyota USA did not issue a comparable extension. Affects only the North American 2.0L non-hybrid (regular CVT); hybrid eCVT models are unaffected. Left unaddressed it can ruin the transmission.

Common Symptoms

  • Loud humming or droning that increases with speed
  • Whining or grinding from the transmission
  • Noise initially misdiagnosed as a wheel bearing
  • Progressive worsening over time

How to Fix

Diagnose to isolate the noise to the CVT rather than a wheel bearing. Caught early, the carrier/variator bearing can be replaced for far less than a full unit; if it destroys the transmission, replacement runs roughly $7,000-$10,000. Canadian owners may qualify for the extended-warranty repair.

Typical repair cost:$3,000 - $10,000

On the 2018-2022 Toyota C-HR, the C-HR's CVT (K120) exhibits noticeable hesitation on acceleration and the typical CVT 'rubber band' effect where engine RPM rises before the vehicle accelerates. The lag between throttle input and forward motion is more pronounced than in competing vehicles.

Common Symptoms

  • Delay between pressing gas and vehicle accelerating
  • Engine RPM rises before speed increases
  • Hesitation when merging or passing
  • Jerky low-speed acceleration

How to Fix

Toyota released ECU/TCU software updates that improve throttle response mapping. Visit dealer for the latest calibration. CVT fluid change with Toyota CVT Fluid TC at 60,000 miles improves responsiveness. Some owners install aftermarket throttle controllers (Sprint Booster or Pedal Commander) to reduce the electronic throttle delay.

On the 2018-2022 Toyota C-HR, the in-tank low-pressure fuel pump in the C-HR can fail due to a defective impeller that deforms and contacts the pump housing. This causes reduced fuel delivery, resulting in rough running, hesitation, and potential engine stall. Toyota issued a recall (21V-251) for a related fuel pump issue affecting multiple models including the C-HR.

Common Symptoms

  • Engine hesitation during acceleration
  • Engine stall at idle or low speed
  • Long crank time before starting
  • Check engine light with fuel system codes
  • Loss of power at highway speeds

How to Fix

Check recall status with your VIN at toyota.com/recall. Affected vehicles receive a free fuel pump replacement at any Toyota dealer. If out of recall coverage, replace the fuel pump module assembly. Use only OEM or Denso replacement pumps.

Owner tips & cautions

  • WarningThis is a safety recall - the engine can stall without warning at any speed. Check recall status immediately.

On the 2018 Toyota C-HR 2.0L I4, the Skid Control ECU can misread a small increase in EPB motor circuit resistance (from expected oxide film, typically after the parking brake has sat unused) as an open circuit, illuminating an EPB warning and potentially leaving the brake unable to release or apply. If it will not apply and the vehicle is parked on a grade without being in Park, a rollaway is possible. Covered by Toyota recall H0W (~28,000 units, 2018 C-HR).

Common Symptoms

  • 'EPB Malfunction' warning on dash
  • Parking brake will not disengage
  • Parking brake will not engage
  • Risk of vehicle rollaway on a grade

How to Fix

Under recall H0W, an authorized Toyota dealer reprograms the Skid Control ECU at no charge. Verify eligibility by VIN at the Toyota/NHTSA recall lookup.

On the 2018-2021 Toyota C-HR 2.0L I4, owners report the 12V battery going flat after the car sits for a few days, requiring a jump start, and the small factory battery failing early. The Data Communication Module (DCM/telematics) drawing standby current before a software update is a cited cause; forums note a customer-satisfaction campaign providing a DCM software update. Short trips that don't fully recharge the battery worsen it.

Common Symptoms

  • Dead battery after sitting a few days
  • No-crank / slow crank on cold start
  • Needing frequent jump starts or roadside assistance
  • Battery failing around the 2-year mark

How to Fix

Test for parasitic draw and apply the DCM software update (customer-satisfaction campaign) where eligible; replace with a correct-spec battery. A trickle/maintainer charger helps cars driven infrequently.

What you need to diagnose it

The fix here starts with a test, not a part — which repair you need depends on what the test finds.

On the 2018-2022 Toyota C-HR, the C-HR's Entune/Audio Plus infotainment system freezes, restarts randomly, and drops Bluetooth connections frequently. The touchscreen becomes unresponsive requiring a full system reboot. Apple CarPlay and Android Auto (where available) can also disconnect intermittently.

Common Symptoms

  • Touchscreen freezing or going black
  • Bluetooth disconnecting during calls or music
  • System rebooting while driving
  • Backup camera delayed or frozen
  • CarPlay/Android Auto disconnecting

How to Fix

Perform a hard reset by holding the power button for 10+ seconds. Visit dealer for head unit software update (multiple updates have been released addressing stability). Ensure phone Bluetooth firmware is up to date. For persistent issues, head unit replacement under warranty. Some owners upgrade to aftermarket head units for better reliability.

On the 2018-2022 Toyota C-HR, the C-HR's dramatically sloped roofline and small rear window create significant rear visibility blind spots. Compounding this, the backup camera can fail or display a blurry/washed-out image, particularly in cold weather or after car washes where moisture enters the camera housing.

Common Symptoms

  • Backup camera image blurry or washed out
  • Backup camera intermittently goes black
  • Condensation visible inside camera lens
  • Camera image has lines or distortion

How to Fix

For camera moisture: apply silicone sealant around camera housing to prevent water intrusion. Clean camera lens with glass cleaner and soft cloth. For camera failure, replace backup camera assembly (Toyota 86790-10070). Aftermarket replacement cameras are available for $50-100. Add blind spot mirrors to rear window pillars to improve visibility.

On the 2018-2020 Toyota C-HR 2.0L I4, c-HR owners widely report the factory windshield cracking or chipping from minor stone strikes far sooner than on other vehicles, with cracks sometimes appearing to spread spontaneously (including on stationary cars at very low mileage). Owners attribute it to thin/low-quality OEM glass and the steep windshield rake. Because the forward-facing camera for pre-collision/lane-keep is bonded to the glass, replacement also requires camera recalibration. CarComplaints lists windshield chips/cracks as the most-reported problem for the 2018 C-HR, with a separate 2019 complaint page.

Common Symptoms

  • Windshield cracks from small rock chips
  • Cracks spreading rapidly across the glass
  • Chips appearing at low mileage
  • Cracks reported to appear without obvious impact

How to Fix

Replace the windshield (OEM or quality aftermarket) and have the dealer or glass shop recalibrate the forward camera. Some owners add clear protection film to reduce recurrence. If no external chip is visible, some dealers replace it under warranty as goodwill.
