Toyota Corolla knocking problems

Filed Jan 21, 2026 · Transmission · MD

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 should the transmission ultimately fail. It has become increasingly apparent that Toyota is not conducting a thorough investigation into these matters and expects the customer to bear the expense beyond the scope of the standard warranty. Beyond the immediate safety concerns for the owner, there is a significant risk of collision should the vehicle experience a loss of control or erratic behavior. Thank you for your time and assistance in investigating this matter.

I recently 6 weeks ago bought a used certified 2016 Toyota Corolla with 43,000 miles. I have been going back and forth with Toyota since the day after I bought it about the many mechanical issues that pose a major safety risk. The car shudders/vibrates when accelerating, knocks when backing up. And when making turns the car shifts hard side to side with a shudder and wobble in floor board of car. It feels as if you don’t have control of the vehicle when driving. It has lots of loose play in the front end and steering really the whole car. It also has a problem going up hill and jumping on fwy a major problem accelerating. They keep telling me car is working per design but this is a lie. I have taken it to 2 other mechanics who told me this car has major issues safety ones to take it back. Toyota fixed the control arms stating that might be what it is but the same problems remain. I am afraid to drive this vehicle and they refuse to figure out the problems and fix them. 2 days after buying it I told them take the car back it has too many mechanical issues they refused. I don’t know what to do I cannot continue driving this car like this and in the rain it could barely handle also. The car has a feeling of loss of control like the whole frame of car is loose. I need help and don’t know what else to do I’ve taken the car back to them about 15 times. They continue to lie and say nothing is wrong even though when I test drove it with the head mechanic. He admitted the car has major issues but told me he did not want to get involved and I would have to take it up with management. I traded in my 2011 suv that was in good working order to buy this smaller car so my daughter could also learn to drive. They should have never sold this vehicle with this many mechanical safety issues please help.

A knocking noise is coming from the front of car. Noise correlates with car motion. Worn parts in suspension were replaced by Euro Car Doctor in Costa Mesa. One problem complies with Toyota Technical Service Bulletin. Noise continues. The electronic invoice has photos of worn parts. Euro Car Doctor documents concern. I do not trust the local Toyota dealer service department to properly inspect the vehicle.

I was traveling on the interstate through Missouri through to Kansas to get back to California on July 5, 2022 in my brand new just got april 18 2022 toyota corolla hybrid when the entire electrical panel went out on my car. i was driving the speed limit on the interstate with the AC on in 109 degree temps when the whole electric panel went out it was out for about ten minutes before it came back on and when it did i had no AC. i was literally in the middle of the desert, there were no stops coming up, no towns, no shade, nothing! and thank god i had just dropped my nine year old son off in indiana or he could've died with me. the AC condenser on this car is located RIGHT BEHIND the front grill of the car, which has over one inch openings in it and toyota is specifically not covering this part under warranty because they know this is a faulty design. i understand and have been told that AC is a luxury but its not for that one week old baby that is going to be traveling with their family is this car and they have no idea that a PEBBLE (is what toyota told me knocked my ac out in the desert!) is going to knock their AC out and that baby will die. Toyota needs to recall this car or put a screen behind the grill i dont care but the public needs to be made aware how easy it is for the AC to be knocked out. additionally the toyota dealership here said that they can repair it for 1400$ but there's nothing to stop it from happening again as soon as i drive off the lot because there is nothing protecting the condenser. i have a brand new car that is broke and cant be repaired and toyota has told me they stand by their design and IF THEY decide to do a recall i will be notified. please notify the public about this! it is hot everywhere and children will die. i cant even go back to pick my son up and now have to fly him out because i dont have AC in my brand new car. like seriously! think of the children and the people who have no idea how easy it is to go out! thank you!

Vehicle is jerking and shuttering while in motion between 4-20mph cold or hot and A/C on or off. This occurs before braking and seems to jerk forward. Tends to occur more often in parking lots. This issue is accompanied by aggressive engine shaking and all passengers can feel the rough idle. This issue is progressive getting worse with time over the last few months. Took vehicle to dealer, spark plugs was the assumed issue from technician. First diagnosis was spark knock. Replaced spark plugs, did not fix the problem. Second diagnosis was "off center steering wheel causing stability control to override driver throttle inputs and lead to jerky operation" case is ongoing and a resolution hasn't been provided or solved. Toyota corp. Is opening an investigation/case.

There is a severe safety issue with the cruise control. In reading corolla on-line forums, it appears that it has been a toyota problem for quite some time ' not something specific to my vehicle alone. The first couple of times I had to take it off cruise - as it wasn't safe in any way. The last time I set it well below the desired speed with no other vehicles in view so that I could try to allow it to run its complete cycle. I wanted to see exactly what would happen if allowed to run its course. When I set the cruise control, it sets fine. Then, when I go down a very slight downhill, the engine revs wildly up to 4000 RPM, hangs there for a long while and pulls the car up well over the set speed. Then it drops, inexplicably, to approx. 3000 RPM, hangs for a bit, and then drops down to where it should be - approximately 1000 -1500 RPM and the speed goes back to normal. What good is a cruise control if you need to babysit it? You shouldn't have to take it off because it's accelerating rapidly out of control! I read someone's account of their car accelerating until they came up behind someone else, the car brakes came on, and they were nearly rear-ended by the person behind them because of the sudden braking. It sounds like a ticking time bomb!
