“From oct 10 to oct 14, I parked my car at off airport parking lot for 5days. When I came back, my car didn't start. My car was towed to the closest Honda dealership. I got the inspection report from the dealership stating that the reason why my car didn't start is due to bad gas. I went to the gas station, where I pumped my gas last time before I flew out of atl, to check with them. They provided me a copy of the system status report of 10/9/20 showing that there were no issues. …”

“2020 Accord 2.0t sport 10,600 miles I was traveling across the state with periods of light and heavy rain. About halfway into my ~280 mile trip I stopped for a red light. When accelerating from the light, my car lost power and the accelerator did not work. I coasted to the side of the road and noticed the check engine light blinking, with no other warning messages. I shut the car off and restarted to find no engine light or warning. I was in the middle of nowhere late in the evening so I continued to the destination. …”

“Driving on i95 near lumberton nc at 78mph in econ mode with cruise on, went to pass vehicle after cruise slowed me down, stepped on gas and response felt different, realized I was slowing down while stepping on the gas. Noticed cel light and continued to slow down. I thought car was drifting but the rpms still showed engine on. Got to safety apron and realized car was in limp mode. Managed to get to exit ramp. Sitting on ramp noticed that the engine, when you tapped the gas pedal, was rough but seemed to idle ok. Towed to nearby dealer. …”

“I leased my vehicle a year ago, I had electrical issues with my old car so I wanted a brand new car that was reliable and safe for me and my children. In the first months the car was fine but after about 4 months the car would smoke from the exhaust pipes randomly. I took it for maintenance as the car system directed but the repair shop never said there was anything wrong with the exhaust system. A month or so past and one day I got in the car and all the lights on the dash board were in. I was so freaked out because it was a new car and no warning lights should of been on. …”
