Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“There have been a couple of incidents where I will be driving and my car suddenly jolts and coasts to a stop. It seems as though the car is being placed in neutral while I am driving because when I press on the gas. It will just rev the engine. The check engine light will turn on as well. I typically turn off and on the car and the car will then work just fine. These incidents seem to happen when I am driving on a city street.”
NHTSA complaint #11400022, filed 2021-03, 20,000 miles“My car lost motive power while driving about 20-25 miles per hour on a city street. I was turning towards the right into a roundabout when the car would not accelerate even though I was pressing on the gas pedal. The car continued to coast for a few seconds and then the engine started again. I do not think the car went into neutral because I did not have to push the ignition start button.”
NHTSA complaint #11121786, filed 2018-08, 58,000 miles“2015 Acura TLX 2.4 model has jerking between 1 and 3rd gear. While driving on a highway if feels as if the wheel alignment is off had a wheel alignment done didn't fix problem. Steering wheel needs to be held at an angle to drive straight.

NHTSA complaint #11252788, filed 2019-09, 70,000 miles“The car automatically switches to neutral and shuts off while driving. I bought the car brand new from john eagle Acura and have had this problem the entire time that I have owned the vehicle. The dealership replaced the transmission and starter on the car less than 3 months after pruchase. The car continues to switch gears on its own and shuts off! The dealership says that nothing is wrong with the car. Please beaware this car is not safe to drive!!!”
NHTSA complaint #11286887, filed 2019-12, 5,000 miles“Since pickup, transmission has not acted properly--when transmission is first engaged it either thrusts the car forward or does not respond at all to foot on exilherator----I believe at this point it is a safety hazard. I do not allow my wife or kid to drive the car. It is brand new.”
