Engine, suspension or unknown ?: three of the 4 motor mounts are broken and not supporting the engine. The one remaining motor mount is under extreme stress and can fail anytime. I have had two dealer service managers confirm this problem and both have said that they are not covered under any warranty or recall. Both have warned me that it is not safe to drive because if the last mount fails it could cause an accident. The condition of the roads and freeways make it very hard to avoid pot holes and I hold my breath every time I hit one to see if the motor is ok. Electrical: 1. After I had the air bags that were recalled replaced there is an electrical ?? Problem that turns the radio on and off (I can usually change it by beating on the steering wheel but that doesn't always work.) 2. Occasionally when I remove the key it continues to beep until I beat on the steering wheel. 3. Often when I hit a bump in the road there is a loud electrical (cracking like a short) sound in the speakers that sometimes I can stop by beating on the steering wheel. If it doesn't stop I pull over and turn the car off and restart it. 4, the door and slider locks do not work on the passenger side with the remote or the locks on the driver's door. I have to roll the window down so a passenger can unlock the door or slider manually. These problems have been going on for the last 2+ years. I am a very low income 75 year old senior who can't afford $1000+ to replace the failed motor mounts. I've put out $750 in the last year trying to solve the electrical issues and transmission flush.

1.starting in early july 2016, my honda odyssey began randomly accelerating on this own, without a human depressing the gas pedal. While in drive, the car accelerates on its own. 2.when this happens, I have to press extremely hard on the brake to get the vehicle to stop. Then, when I place the car in park, the RPM increases to between 5,ooo and 7,000. Again, this is without a human depressing the gas pedal. 3.this issue seems to occur when the air conditioning is turned on, and it feels like the cruise control system is taking over even though it's turned on. 4.this issue doesn't always happen immediately once the car is turned on. It sometimes takes a random amount of time to manifest itself while the car is being driven. 5.I've faced this issue at least 15 to 20 times over the past 2 months. 6.obviously, this issue is extremely dangerous and may result in severe injury or death for the driver and other motorists. And therefore, it must be dealt with immediately. The honda dealer said that there is nothing wrong, but only checked the vehicles cpu. This is insufficient because, as indicated above, the cpu will not register an issue in idle mode or when the problem isn't actually happening.
