Mazda MAZDA6 jerking problems

Filed Apr 22, 2026 · Acceleration, Brakes · FL

The vehicle exhibits dangerous electronic malfunctions. A licensed technician (MV-113255) has confirmed a sporadic unintended acceleration defect where the cruise control 'decrease' button causes the vehicle to increase speed. Additionally, the vehicle repeatedly enters 'Limp Mode' in active traffic, causing a violent jerk and a total loss of acceleration while displaying a 'Smart City Brake Support' (SCBS) failure on the dashboard. An independent inspection also documented gross mechanical neglect, including loose battery terminals and a loose transmission bellhousing bolt, which may contribute to these intermittent electrical/safety failures.

Hello i am a 2nd owner of a Mazda 2007 6. And the man i brought car from said it always did it to him as well.i would explain it as in stopping or speeding up the dashboard lights flicker or goes off, the engine gets real loud and car jerks and shakes and loses power check engine light comes on and AT.and Cars dyes in reverse a few times on me. Auto lots said that it is common and known for electrical problems and engine issues and pieces called camshafts position actuator and transmission range sensor and gears. And the man owned before me has replaced them multiple times. Its dangerous to be driving specially on interstate and car stalls or lose so much power that i only get about 20 miles an hour

Situation: CVT tramsmission running smoothly when car was first bought. I am 3 weeks into owning the vehicle and the transmission seems to be going out. I had a diagnostic text run and there are zero computer errors. Issues: high revs and jerking of vehicle when gassed. Whether I am at a stand still or already giving gas. Any increased speed applied by the gas causes the jerking motion. There is a 2-5 second delay from the pedal to the transmission kicking. I have almost wrecked multiple times when this issue started occurring on my drive. This CVT would be considered very hazardous considering the specific problems I am experiencing.

I was driving on a street and my check engine light, tcs/dsc light, sbs/scbs light, mrcc light, and warning light appeared on my dashboard. My car then started putting or jerky. It felt as my car was very weak as if it was going to give out. This is the third time these same malfunctions appeared. Each time it occurred I took my car to the mazda dealership. The first time they did not find a problem because the warning light had already turned off. The second time(september 5), they gave me a new battery and new computer software. It is now at the dealership again. This situation is very scary and I need to know why this is happening

When I take my foot off the gas it stays at the same speed or it speeds up on its own. When I press on the break sometimes it feels like it's not going to stop and just keep going or it jerks forward when I stop. This happens when I am driving on the road and the cruise control is not on when this happens.

Tl* the contact owns a 2009 mazda 6. The contact received a recall notice back in march of 2019 for the federal safety agency campaign number: 18v631000 (suspension, structure). The contact called garden city mazda at 516‑874‑0385 and informed them that the parts to remedy the recall were unavailable. The contact was informed that when the parts arrived, the dealer would email her to have the vehicle serviced. The contact had yet to receive a notification to have the recall remedied. Also, while driving 40 MPH, the vehicle began to jerk while depressing the accelerator pedal as well as when shifting gears. The contact stated the check engine warning indicator would illuminate intermittently both prior and after she experienced the failure. The contact took the vehicle to a local mechanic, but it was not diagnosed. The mechanic suspected that there had been an oil leak that affected the transmission. The manufacturer had not been notified of the failures. The vehicle was not repaired. The failure mileage was 94,000.

Transmission roughly jerks itself into 2nd-3rd gear. When the car has come to a stop and is then accelerated, engine stalls for a few seconds, then slams itself into 2nd or 3rd gear. This poses as a rear-end threat, as the car is forcefully put into gear, causing the car to jerk forward suddenly. For me this only occurs at lower speeds (10-30 MPH). I have researched this problem and many others have come across the same thing.

My vehicle is automatic transmission and last weekend I was driving at the freeway with my family at 70 MPH on cruise and all of a sudden we got big jerk from my vehicle and the vehicle RPM started increasing the same time first I thought someone hit me from back but the gladly the vehicle was in other lane and he honked at me. I then I saw d light disappear on the panel and the vehicle was in very high RPM mode. I didn't know what is happening I safely tried to pull on the right and stopped to see whats wrong but couldn't found anything. I turned off vehicle for a minute and started again. It worked fine for 5 min and as soon as I reached 55 or 60 MPH the d light started blinking again and again I got high rpms and jerk. It almost had caused the accident as the other vehicle almost hit me from the back. It felt like engine braking. Then I drove very low spped on inner city road with my blinkers on to reach home safely. Now dealer is telling me that it will cost me minimum $3000 to replace the transmission. I think its a know issue to mazda and they should fix my vehicle transmission atleast. This vehicle is not safe to drive.
