P0700 on Toyota

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.

The 8-speed automatic transmission can exhibit hesitation, jerky shifts, or a delayed response when accelerating from a stop. Some owners report the transmission feels confused about which gear to select at low speeds.

The Continuously Variable Transmission (CVT) in 2014-2019 Corollas may experience shuddering, jerking during acceleration, high RPM before shifting, and in severe cases complete transmission failure. Issues are particularly reported when accelerating from a stop or during downshifting. Some owners have experienced catastrophic failures at relatively low mileage.

The Direct Shift CVT in the Corolla Cross can exhibit hesitation and delayed response during initial acceleration from a stop or when requesting sudden power during passing maneuvers. The CVT programming prioritizes fuel economy, resulting in a noticeable delay between throttle input and vehicle response. Toyota has issued software updates to improve throttle response in some model years. The issue is more pronounced in non-hybrid models with the 2.0L engine.

Toyota recalled certain 2019 Corolla Hatchback models with CVT transmissions due to pump impeller blades within the torque converter potentially detaching under high-load driving conditions. If blades detach, the torque converter loses hydraulic pressure, causing the vehicle to stall and lose power while driving. This is a safety recall (NHTSA Campaign 19V-252).

The intelligent Manual Transmission (iMT) rev-match system can interfere with smooth shifting, causing unexpected RPM blips and a disconnected shift feel. The system sometimes over-revs or under-revs during downshifts, and the clutch pedal feel is reported as vague.

GR86 models with the 6-speed manual develop throw-out bearing noise, typically a chirping or squealing sound when the clutch pedal is depressed or released. The bearing wears prematurely, especially in stop-and-go traffic. Not an immediate failure risk but worsens over time.

The vehicle hesitates and lurches when accelerating from a slow or rolling stop, particularly at traffic lights or in stop-and-go traffic. The magnetic clutch in the Direct Shift-CVT transmission causes delayed engagement. A class action investigation is ongoing for 2021-2023 models.

The ZF 8HP51 automatic transmission exhibits rough or jerky shifts at low speeds, particularly 1st-to-2nd and 2nd-to-3rd gear changes during city driving. The mechatronic unit's valve body can develop wear causing harsh engagement. Cold weather worsens symptoms.

The 6-speed manual transmission can exhibit grinding when shifting, particularly into 2nd or 3rd gear, and generally notchy shift feel. This is often related to the synchros or the clutch system hydraulics.

The A132L 3-speed automatic transmission in the Tercel is prone to premature failure, typically presenting as harsh shifting, slipping, or complete loss of forward gears. The transmission was designed for economy driving and struggles with sustained highway use or towing. Internal clutch pack wear and valve body issues are the most common failure modes. Many owners convert to manual transmission or source used replacements rather than rebuild.
