2024 TOYOTA COROLLA Power Train Problems

The 2024 Toyota Corolla needs to be added to the list of vehicles currently being investigated for transmission/engine issues. The vehicle in question is currently exhibiting transmission anomalies consistent with those observed in several other vehicles under review, specifically: slipping, jerking, surging forward, hesitation to accelerate from a complete stop, loss of power, droning sound at low speed, odd knocking noise/vibration during idle, unresponsive gear changes, shuddering upon vehicle shutdown, and decreased fuel efficiency. The owner has incurred expenses exceeding $2,000 for rental vehicles and diagnostic services in an effort to resolve these persistent issues. However, as of January 21, 2026, Toyota has not acknowledged the existence of a problem, asserting that these conditions are within normal operating parameters and that the vehicle is performing as intended. A local mechanic has advised the owner that Toyota will not diagnose the issue, but they are likely to offer a post-warranty adjustment...

During a routine transmission fluid service on a 2024 Toyota Corolla Hybrid, I discovered that the transmission model (PA10) is completely unlabeled and cannot be identified anywhere under the hood, in the owner’s manual, or on any visible tag. The only label is buried behind the firewall and not reasonably accessible to consumers or technicians. As a result, I initially attempted to service the wrong fluid port because Toyota provides no visible or clear identification of the transmission model or fill/drain points. Additionally, the factory-installed transmission drain and fill bolts were tightened with extreme torque well beyond normal service specifications, requiring application of high heat and excessive force to loosen. This resulted in personal injury and risk of property damage. The combination of (1) inaccessible transmission identification, (2) inadequate service guidance, and (3) extreme bolt torque creates a foreseeable safety hazard to vehicle owners or technicians attempting basic maintenance. Toyota’s...

My car has 5358 miles. Started car. DRIVE START CONTROL MALFUNCTION LIGHT; CHECK ENGINE LIGHT; SEE DEALER LIGHT all came on. Car would hardly move forward or reverse. Felt like the brakes were on. Heard subtle clicking sounds from engine. Looked this up as I never heard of this. Toyota says you MUST STOP DRIVING ASAP, assuming you "can" drive. You can LOOSE CONTROL of the car. There are many things that can cause the light to come on. Dealer "says" they never heard of this. My car had to be towed. Mechanic found nothing wrong and reset computer modules. I got my car back after 3 days. Dealer says NO GUARANTEE it won't happen again WITHOUT warning. So; anywhere, anytime, my car will just stop driving? HOW IS THIS SAFE? Internet searches show it's NOT UNCOMMON. Toyota makes it hard to file a complaint.

This is an issue I have noticed with my car shortly after I bought it. The problem is that the car has a noticable delay in acceleration when accelerating from a complete stop. After doing some research online, I found that the cause was the car's CVT transmission, and that a delay in acceleration happens with other cars with CVT transmissions as well. This could be potentially dangerous especially when making right turns on a red light or when making unprotected lefts on a green, as the window of opportunity to go is sometimes short in those situations, and delaying for even a second could mean the difference between a collision or a safe turn (especially since there are some fast drivers that go much past the speed limit and will appear from behind a hill all of a sudden). What is especially problematic is that the car will rarely...

Brand new car with 300 miles jerks and jolts leaving from a stop and hesitates going up hill. Feels like car has no power behind it. Forward collision also breaks randomly. Currently at dealership.

Transmission slips from 20-40 mph randomly.

The contact owns a 2024 Toyota Corolla. The contact stated that while driving at undisclosed speeds and decelerating, the vehicle was jerking abnormally. There were no warning lights illuminated. The vehicle was taken to the dealer however, the dealer was unable to determine the cause of the failure. The vehicle had not been repaired. The manufacturer was made of the failure and a case was filed; however, the contact had not received any communication from the manufacturer. The failure mileage was 27,000.
