Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving my 2019 MDX I noticed that the back-up camera was on remaining on, and I could see the road behind by vehicle. I pulled off the road and turned the car off and then restarted thinking this would correct the problem; however it did not correct the problem. I also noticed that the lights that indicate that I am backing up remain on even when the car is in park. Inside of the vehicle, the climate control isn't working. …”
NHTSA complaint #11307893, filed 2020-02, 8,300 miles“The automatic collision mitigation system had a complete 100% lock up of my brakes during a cross of an intersection . Although I was wearing my seatbelt the force of the stop threw my head into the steering wheel. It is a complete miracle that the car behind me did not rear-end me. This system routinely gives false positives when going around corners when you are in the center lane and it beeps and pulses the brakes. This time, the car stopped completely and I hit my head and was lucky to not cause an accident. …”
NHTSA complaint #11292242, filed 2019-12, 18,000 miles“While driving approx. 40 MPH and slowing to turn into gas station, the car completely turned off. I was unable to put car in neutral or get off of road. Tow truck called and had to be drug onto flatbed. Garage replaced battery and still unable to start. Needed to replace timing belt, tensioner pulley, water pump, engine short block and heads. Car with only 4088 miles, no s/s of issue prior to incident, etc. Garage not sure what caused issue, best guess is manufacture defect in timing belt. I asked to end lease or for new vehicle, but Acura denied. …”
NHTSA complaint #11182028, filed 2019-02, 4,088 miles“Infotainment system experiences periodic failures causing inability to control climate/temperature controls, communications, navigation, and vehicle settings including safety settings. It occurs when driving in city and on highway regardless of conditions or speed, when stationary, can at times be corrected by pulling off the road and restarting the car, but sometimes it just takes time to resolve. Acura stated this is caused by the connection to the cell phone, but occurs even when no phone is connected to or in the car. …”
NHTSA complaint #11351669, filed 2020-08, 300 miles“While driving at highway speed, there was single pop sound that seemed to come from inside the dashboard between the on demand multifunction display (odmd) and the instrument panel. The navi screen then became solid black. After a very short time and while still at highway speed, the navi screen briefly showed the view from the backup camera. After a few seconds both the navi screen and the odmd screen became solid black and remained that way. Then, within seconds, light colored, grayish smoke began flowing out into the vehicle from the cd slot on the odmd. …”
