2020 HONDA ACCORD HYBRID Complaints

Overnight while parked in the garage, the front windshield became cracked without signs of impact. The next night before I had even had the chance to bring it in for a scheduled inspection at the dealership, the crack spidered out to cover almost 15-20% of the windshield. When I took it into for inspection at the dealership, they also mentioned that it looked like there was no impact and the crack was internal to the glass. They agreed that it looked like the same situation as described in Honda TSB 20-118, but said that it could not be covered because it wasnt in the identified VIN range even though it looked like a similar situation described in the TSB.

Without driver intervention, the vehicle engaged the brakes. Threw both passengers forward until the seat belt restraints engaged. Bruising both passengers shoulders. The vehicle would not respond to either pedal - brake or gas for a few seconds. There was no visible traffic in front of us. The day was clear. And no construction or overpasses. The vehicle was taken into a certified Honda dealer and inspected. No “flags” or diagnostic issues found. The car was driven by the dealer. The issue wouldn’t reproduce. The dealer stated that they did find a large “smashed” bug on one sensor and wondered if it could have caused the issue. Prior to the vehicle initiating the panic stop, no indications of a event were posted on any device in the vehicle

On 2 incidents, I've had the collision mitigation braking system (CMBS) issue driver warnings/alerts and automatically hit the brakes without warning when there are no obstacles in front of the vehicle and it has not deviated from its lane. Both incidents occurred during highway speeds. 1 incident was in a construction area where the car entered a steep decline and then rise as the construction was part of lane resurfacing. The 2nd incident was while driving over an overpass (not sure, but possibly a steep incline).

My car is a hybrid. At times, a Very loud humming noise is produced, due to glitch in software with the ANC. Noise starts and stops suddenly, intermittently, without warning, and is a safety hazard. Noise can build to be extremely loud and jarring, and can last for several minutes. Honda claims this is a cosmetic issue only and they are working on it. But the issue has been repeatedly reported by thousands of drivers over a multi-year period. Honda is ignoring any real resolution. Please help! This is frightening and disruptive, and makes operating the car unsafe. Thank you. It started about 1 year after ownership and was occasional. IT is now happening multiple times, every time I drive my car.

I was driving yesterday accordingly to the speed limit on a main city street. There were no cars in front of me AT ALL when all of a sudden my car hit the breaks 3 times back to back out of nowhere causing my car to swerve! I felt completely out of control of my vehicle and I am so thankful I wasn't on the highway and that no one was near me! I first noticed issues with the breaking system, previously on 3 other occasions throughout my time of owning/leasing the vehicle. 3 other occasions before receiving an alert on the screen that read "the brake system has a problem. Avoid high speeds and sudden braking. Have your vehicle checked by a dealer immediately." That was February 13, 2022. I called immediately to take my car in and was told I would have to pay out of pocket to have this issue addressed which seems outrageous to me since it is something that I have no control over. So without the ability to pay such a high fee for a vehicle that I thought would keep me safe, I took it to a local auto shop and had my brakes checked while I had my routine maintenance done. I was told everything was fine, which in my opinion indicates it is at fault of the manufacturers.. I don't want to die before something is done. There have been many claims about the same thing happening. I'm truly shocked there hasn't been a recall due to this issue.

I have had two (2) separate incidents of the automatic emergency braking system engaging suddenly & without reason as I was driving. Once on a residential street & the second on the freeway at approx. 65 mph. The AEBS released very quickly each time, but is a highly and potentially dangerous thing to happen. There are numerous reports & complaints about this in the 2016-2019 Honda Accords, but it is now happening in the 2020 year cars.

This seems to carry over from problems with prior year models. I can be on the highway with no vehicle in front of me and the brakes apply by themselves (foot not even near the brake pedal). It is a brief braking, but it can be dangerous when someone decides to ride on my tail. I notice it does happen when I'm going around a curve and a railing next to me on the outside of the curve is near the lane. It also happens at times when a vehicle is in the next lane (right or left) and slightly ahead of me, even on a straight-a-way. It has happened multiple times. Date below is just the latest. I approximate my speed at 65MPH and my car low mileage.

While driving at highway speeds (50 -55mph), the ANC (active noise control) unit delivers a loud Booming sound through the speaker system. The sudden and unexpected booming noise startled the driver causing temporary loss of control of the vehicle. The solution has already been identified in a Service Bulletin from Honda as Service Bulletin 21-053. The ANC unit has incorrect software and requires replacement to fix and eliminate the safety hazard. The issue was noted June 29th, 2021; but, has not been escalated as a Safety Recall. I have replaced the ANC as directed by the Service Bulletin and it has resolved the problem; however, other Honda vehicles have this same safety issue and if not Recalled will continue to be a safety concern for all drivers on our highway. I would like to see this escalated to a Safety Recall level and customers notified to replace. I am disappointed that Honda has not proactively Recalled this.

The contact's client owns a 2020 Honda Accord. The contact stated that while his client was driving at about 45 MPH, the vehicle inadvertently accelerated on his own, drove off the road and drove down in a steep embankment, hit 8-9 fence posts, ramped up over the driveway of the embankment, and crashed into a tree. The contact did not know whether the air bags deployed. The contact's client sustained severe injuries including broken bones. The contact's little brother who was in a forward-facing child seat in the rear driver's side seat was pronounced dead at the scene. A police report was filed. The contact's client and her brother were transported to the hospital by emergency services. The vehicle was towed to a garage where it was totaled. The dealer and manufacturer were not notified of the failure. The failure mileage was unknown.

I was on the Freeway ramp from I11N to I215 in Henderson, NV. I tapped off the interactive cruise control because my exit was Gibson - immediately after the ramp. Within a few seconds, the car braked heavily on its own, no dash warnings, and almost caused me to get rear ended. I pushed on the brake and then the gas and it stopped the car from braking on its own.
