What 653 owners told NHTSA about the 2019 Honda Accord Plug In Hybrid

For the past 3 years my car has started breaking on it’s own when there is no reason to. There are no cars or anything in front of me. It has been doing the breaking on it’s own more often and now is worrying me more. It once breaked me when i was on the interstate going 75! And other times when I’m in heavy traffic. I need something to be done about this. I don’t want to have my kids with me when this happens again and it causes an accident..I don’t need my car to cause an accident at all. Please let me know what will be done about this problem with my car. I can’t afford shop fees to get my car looked at. I am asking if this problem can please be fixed. Thank you. Have a good day.

The automatic braking system malfunctioned and started to brake for no reason, with no car in front and/or no other safety risk. Luckily there was no car behind me which most likely would have resulted in a rear end collision; which put myself and other at risk. The warning lamp on my dash was flashing brake as the vehicle was braking. I am afraid to drive the car due to safety concerns.

For wheels tpms system warning keeps turning on stating I have low tire pressure. I would check tire pressure and it is normal 33-34psi which is the recommended tire pressure by Honda. I would recalibrate the tpms and it would turn back on after driving 20 miles. I do this daily and honda dealers claim there is no issue. When I turn on a curving road if there are cars parked on the street the emergency brake system would turn on and start braking.

AEB was applied three times without need since I have owned the car (purchased used in May 2022). All three times were not warranted and I was nearly rear ended once. First time occurred while merging onto a highway. The AEB system appeared to confuse the concrete dividing wall (which ends at the merge point) and braked unexpectedly. I was nearly rear ended. Second instance occurred while traveling at highway speed on a two lane freeway. I was in the left lane and a vehicle in the right lane began to slowly approach the dividing line (never crossed) and the AEB system activated. Third instance occurred when changing lanes on a two lane highway (right lane to left lane). Car braked suddenly for no reason. It appeared to confuse a large black patch (fresh road repair) in the middle of the road with an obstruction. No other cars were present.

There have been two incidents where my 2019 Honda Accord braked extremely hard and it was out of my control. The first incident was while I was exiting a highway on a rainy night at approximately 30mph, I had cars behind me that had to brake extremely hard due to my braking system which could have caused a rear end collision. The second incident was while I was driving approximately 50mph on a small two lane highway, I had other cars behind that had to swerve to avoid a collision once again. My car also detects many crack repairs on the highway as lane lines and attempts to depart the actual lane. I have to force the steering wheel to stay in the accurate lane. Unfortunately, I no longer feel safe driving my own car.

My Honda Accord has randomly started breaking by itself. I was not pressing the brake just the gas as I was driving and it wouldn’t go as I pressed the gas again . The dash flicked off and came back on and it allowed me to go as I pressed the gas . This could result in a bad accident if it happens on the freeway at 60+ mph. I’m very nervous to drive this car as I have 2 children in it often as well. Please make other 2019 Honda Accord owners known as well as this could happen to them too.

Today, April 23, at around 12 pm, I was driving through my neighborhood, on a straight line at about 25 mhp with clear view no obstacles in sight keeping my foot on the gas pedal, when suddenly the car applied the emergency breaking, with flashing indication on the dashboard that said BREAK. It was a very rough yank. It's something I would expect at a near collision situation. But there wasn't anything ahead of my car in hundreds of feet. I believe the automatic emergency breaking misfired. I am very concerned about driving with it engaged now, so I have to turn it off every time I start my car. There is no way to turn it off permanently.

When I make a turn left or right even the slightest turn on the road and no matter the speed the Traction Control lights up And immediately at the same time the breaks are applied automatically by the car itself, making my car slow down thus putting me in danger of being hit by the car(s) behind me. Then, all the warning lights start to appear on the dashboard. And they stay on for about 30 - 40 mins then they disappear but themselves. Stopping the car and turning it back on doesn't make them disappear. I've taken the car to the deanship and they said it was the alignment of the tires and that they fixed it but as soon as I drove off the dealership it happened again. I happens every single time I drive. I'm afraid to take the freeway because the self breaking system is so abrupt that it's a miracle that I've not been hit by another yet. I've had this issue since at least 25th of January of this year 2022. For a car to apply breaks by itself because I'm making a slight turn is dangerous and it's only a matter of time before someone gets seriously injured or worse. I was scared today because I was going 27miles an hour on a regular street when the car applied breaks by itself and the car behind me honked at me. But I never even touched the break paddle. Please take this issue seriously, it's very dangerous to drive like this.

On March 21st, 2022, I was driving between 35-40mph in clear conditions. I had adaptive cruise control, and lane mitigation on. My vehicle flashed “BRAKE” on the instrument cluster and HUD. The vehicle slammed on the brakes. The braking force was strong enough to lurch me forward and in the process of the vehicle braking, my steering wheel veered to the left and I almost hit a divided barrier. There were no cars in front of me or any obstructions in the way that would have activated the emergency braking. This is the second time in a year my car has done this, but the first time that the braking changed the vehicle’s direction.

I continue to have intermittent instances of "phantom braking" during highway driving when there is no vehicle near me in front. I am driving at 70 mph when the car suddenly slows and the red BRAKE warning flashes on my dashboard. It does not happen often, but once is all it takes for an accident. I have reported this to my Honda dealer over the few years I have had the car. I reported this to you a couple of years ago and am reporting it again after reading recently that your are investigating my model for the problem.

This is a follow up for NHTSA complaint 11452424. After the engine light came on along with other warning lights, like a Christmas tree and taking the vehicle to a Honda dealership with a almost 3700.00 repair bill for a vehicle with with under 88,000 miles. The dealership said the vehicle needed a head gasket. The problem is the dealership did not provide the error code numbers. They just gave a price due too coolant going into cylinder number 3. I asked the service rep for a break down the for repairs, which he said was provided. The only thing provided was coolant leaking into cylinder 3 with no codes that the dealership found with the engine light on. I filed a complaint with Honda to off set the repair cost. Mind you we are talking about a head gasket. Honda denied the claim and referred to lack of maintenance. When I told the representative I do my maintenance. He said it was because the dealership wasn’t making money. Who in their right mind would pay 144.00 an hour maintenance when they can’t be up front and provide codes that were thrown on engine light for repair bill. I think NHTSA needs to investigate Honda’s technical service bulletins regarding cylinder misfires in 1,2,3 and 4. I am quite skeptical that a dealership can not list error codes on a repair estimate that they aren’t hiding something. My family will never purchase another Honda and I will share this Story with everyone I know. Something is being hidden if the dealership doesn’t provide error codes. I have never seen this in my 30 plus years of driving.

I would like to add a comment on the "phantom braking" as I have experienced it with my car several times. I am glad to see a formal investigation has been launched. I think a way to try and replicate this issue is to attempt to pass another vehicle (that is in the adjacent lane) BUT ensuring you are doing this on a curved road way. ...At some point the Accord gets "confused" when it looks liked it is "lined up" behind the other vehicle in the adjacent lane. It is real.. Please find a solution and bring this to a resolution. Feel free to contact me for further explanation. I cannot recall the exact date this incident has happened to me; hence I am putting in today's date.
