On the 2019-2020 Toyota Yaris Skyactiv-G 1.5, on certain 2020 Yaris Hatchback and 2019-2020 Yaris Sedan vehicles - the Mazda2-derived cars designed and manufactured by Mazda, NOT the Toyota-built 1NZ-FE hatchback - the low-pressure fuel pump in the tank may stop operating. Warning lights may appear on the instrument cluster and the engine may run rough; the engine can then stall, sometimes while driving at higher speeds, and may not restart. NHTSA campaign 21V617 covers about 31,300 vehicles; Toyota's internal numbers are 21TA05 and 21TB05. This is a defect of the Mazda-built car only - it has nothing to do with the 1NZ-FE Yaris hatchback sold through 2018.

Common Symptoms

  • Warning lights or messages and rough engine operation may precede a stall
  • Engine stalls while driving
  • Engine may not restart after stalling

How to Fix

Free remedy under NHTSA recall 21V617 (Toyota Safety Recall 21TA05 / 21TB05): any authorized Toyota dealer replaces the low-pressure fuel pump with an improved one at no charge. Check the VIN at nhtsa.gov/recalls or toyota.com/recall. If warning lights or rough running appear, or the car stalls, before the remedy is applied, do not keep driving it - a stall at higher speed is the crash risk the campaign names.

On the 2016-2020 Toyota Yaris Skyactiv-G 1.5L, the 2016-2018 Yaris iA and the 2019-2020 Yaris sedan are rebadged Mazda2s and carry Mazda's Connect head unit, not a Toyota system - so this failure does not exist on the Toyota-built XP130 hatchback. Owners report the display going black and the unit entering an endless crash-and-reboot cycle, sometimes triggered by a specific USB device or by switching between a Bluetooth call and a streaming audio app. The reverse camera image also fails to appear or freezes, which matters because it is the federally required backing image. The root cause on the Mazda side is head unit firmware, aggravated by non-compliant USB cables/drives drawing on the port.

Common Symptoms

  • Center screen goes black and restarts repeatedly
  • Head unit locks up when switching between phone call and audio app
  • Backup camera image missing, frozen or delayed when shifting to reverse
  • USB source not recognized
  • Audio cuts out with the screen

How to Fix

Have the dealer flash the latest Mazda Connect / head unit firmware - most reboot-loop cases are resolved by the software update rather than hardware. Disconnect all USB devices and test; a failing USB hub board in the console is a known secondary cause and is replaceable separately from the head unit. For the camera, check the camera harness connector at the trunk lid grommet for chafe and corrosion before condemning the camera. A battery disconnect resets the unit but is only a temporary workaround.

On the 2016-2020 Toyota Yaris Skyactiv-G 1.5L, the Mazda-sourced 6-speed automatic in the 2016-2018 Yaris iA and 2019-2020 Yaris sedan (a completely different unit from the Toyota U340E 4-speed in the hatchback) draws consistent owner complaints of a whistling or whining noise during the 1-2 and 2-3 upshifts, plus a grinding or clunking noise when selecting Drive from Park. Reports range from a noise-only nuisance to units replaced under warranty, and a few owners describe progression to gear slippage and a stall with audible metal-on-metal. Because this transmission uses a very small lock-up-early torque converter for economy, converter shudder and fluid degradation show up earlier than owners expect for a Toyota-badged car.

This issue also affects: Toyota Corolla, Toyota Corolla Hatchback, Toyota Highlander

Common Symptoms

  • Whistling or whining during 1-2 and 2-3 upshifts
  • Grinding or heavy clunk shifting from Park into Drive
  • Shudder at light throttle around 35-45 mph
  • Slipping or flare between gears in advanced cases

How to Fix

Have the noise documented while still in powertrain warranty - dealers have replaced these units under warranty for the whine. Outside warranty, start with a proper drain-and-fill using the correct Mazda FZ/ATF-FZ specification fluid (Toyota WS fluid is NOT the correct spec for this Mazda unit and using it makes shudder worse), then re-evaluate. Persistent 1-2 whine with grind on engagement usually traces to the torque converter or pump; replacing the converter and flushing the cooler is the common repair short of a rebuild.

Typical repair cost:$150 - $3,500

On the 2007-2019 Toyota Yaris, the Yaris has been named in seven separate NHTSA campaigns on tire and loading information. Six concern the load carrying capacity modification (addendum) label and one concerns the spare tire's inflation. The addendum label is a separate label on the driver's side center pillar, next to the Tire and Loading Information placard. FMVSS 110 requires it when accessories above a set weight are added between factory certification and first retail sale, and it states how much those accessories reduce the vehicle's load carrying capacity. When the addendum label is missing, wrong or unreadable, a driver can overload the car without knowing it, which degrades braking, handling and tire load margin and increases crash risk. The campaigns: 09V223 (Toyota; accessories fitted at Toyota vehicle processing centers; the filing covers 1,348 vehicles built 2 June 2008 to 4 May 2009, including 2009 Yaris sedan and hatchback); 10V035 (Gulf States Toyota, 2008-2010 Yaris) and 10V036 (Southeast Toyota, 2007-2010 Yaris), both for vehicles sold without the required addendum label; 16V236 (Southeast Toyota, 2016, label does not reflect the weight of installed accessories); 17V295 (Gulf States Toyota, 2017: the spare tire was not inflated to the pressure stated on the Tire Pressure Label); 19V244 (Gulf States Toyota, 2019, label text may become illegible); and 19V503 (Southeast Toyota, 2017-2019 Yaris iA with factory-installed floor mats, label incorrect). Most are distributor campaigns, so they apply only to cars that passed through those distributors or processing centers.

Common Symptoms

  • Door jamb tire and loading label shows an incorrect vehicle capacity weight
  • Label illegible or missing
  • Spare tire pressure on the label does not match the spare
  • Vehicle unintentionally overloaded

How to Fix

Free remedy in every case. For the six label campaigns the owner receives a corrected load carrying capacity modification label to place over the old one (on 10V035 and 10V036 the dealer will install it on request; on 19V244 dealers provide it). For 17V295 the dealer inspects the spare tire and adjusts it to the pressure stated on the Tire Pressure Label, which is correct. Check the VIN at nhtsa.gov/recalls; more than one of these can be open on a single car. Ask Toyota or the responsible distributor for the VIN-specific corrected load information; do not subtract accessory weight a second time if it was already included in certification. For affected 17V295 vehicles, the dealer checks and adjusts the spare to the correct pressure shown on the Tire Pressure Label. For older campaigns, have Toyota check campaign history because NHTSA's VIN lookup may omit recalls over 15 years old.
