I'm experiencing several issues with my 2014 Honda Odyssey: -The radiator fan often stays on after the car is turned off. -I have to press the shut down button 3 times before the car completely shuts off, which is concerning. -After driving for only 20 minutes , the engine temperature spikes to the max which is limiting my ability to get places safely. -The sliding doors only work when the car is off and sometimes even then it won't open after trying 3/5 times. These issues are ongoing never stops, The overheating and fan behavior feel unsafe so we just use the car for very short drives(5mins max). I'm worried about potential engine damage or failure while driving. The sliding doors also pose a safety concern, especially with kids.
>At about 95,000 miles the vehicle engine is making a loud rattling noise until it warms up to operating temperature. > At about 105,000 miles the vans battery starting dying frequently. The battery was replaced and 8 months later it died again. Replaced the battery again and one night the battery light came on along with several of the display warnings flashing and the car made it one mile home before dying and not turning on again. Had a mobile mechanic take a look and they think oil leaking has damaged the alternator. Problem has not been fixed and the vehicle is inoperable.
My van has 2 automatic sliding doors, 1 on each side. The cables for both doors have now broken. So neither automatic door works anymore. This is clearly a common problem. And it's a safety issue for those of us with small children and pitched driveways, where the doors can now slide and trap our children. I can't believe a recall hasn't been issued for this
. We were driving on a freeway in rural Minnesota at around 70 mph when the tire pressure monitor lit up. There were no warning lights before that.We started to slow down and suddenly the dashboard lit up with multiple warning lights and the engine stuttered and quit. Fortunately we were going downhill and managed to coast onto an exit (without benefit of power steering or power brakes) and coasted onto the ramp shoulder. After we stopped, the battery seemed to have power; the starter motor would begin to operate but it would stop in less than a second, the car would not restart and the dashboard showed warnings about the ESC and ABS in addition to other warnings. When a tow truck finally arrived, we described the symptoms and the tow truck driver instantly said "It's the alternator". …
My door came ajar while driving down the road!!! When the dash temperature reads above 96 degrees, the electronics of the rear-sliding doors will not operate. This has occurred since the van was 3.5 month old. The local service dept cannot recreate the issue, and no error code displays on the dash. My baby has been trapped in the backseat, because I cannot open the door. During the hot temps, the door will not open manually. The doors are completely stuck! Once I drive around and the van cools, the electronics/sliding doors operate just fine. This is a huge safety concern. This occurs when the van is parked, because being stationary in the sun allows it to get hotter. Even with it's only 93 outside, the dash May read 101 after sitting in the parking lot for a few hours. Last week, I tried to open it around 3 pm. It would not budge. …
At different times since the purchase of the vehicle in August 2013 the audio system is completely lost. After 1 1/2 years of discussing this with the service department of the local Honda dealership I was finally informed that Honda has an issue with the audio system and paring to the iphones. I since have deleted my phone from the system and no longer leave the blue tooth on but still lose the entire audio system from time to time. The car must be turned off and restarted. Also at times the front collision warning will go off when you have no one around you. I believe it is all tied together. Although this is not a safety issue I feel I have no where else to turn. After contact American Honda and being assigned a case manager all she could tell me was to get a different cell phone. …
I was driving 70mph on an interstate. The battery light came on. There was no immediate change in vehicle performance and there were no odors present so I continued driving for several minutes towards the next exit. About .5mi away from the exit, the ABS, FCW, LDW, and brake lights came on, the air conditioner and console turned off, and the automatic transmission disengaged. This prevented the vehicle from being able to accelerate. The entire vehicle essentially lost power. The local dealer diagnosed the issue as an oil leak in the spool valve that then destroyed the alternator and fried the battery. The manufacturer (Honda) recenty issued TSB 20-023 detailing the problem and repair procedure, but it was limited to the source of the leak, not any of the other components that were damaged. …
I own a 2014 Honda odysey, and the driver door sometimes come open by itself when I am driving. Other times I cannot get in to the vehicle, because I cannot unlock the doors to get into the vehicle, not even using the regular key. When I parked my vehicle, and if by any chance I am able to lock the vehicle doors, then a few minutes later the driver door come open (not unlock) by itself. I cannot leave anything inside the vehicle, because anyone can just get in. Yesterday, 20 March 2017, after I parked my vehicle I was trying to get out and I could not, because I could not unlock the driver door. A very scary feeling. I had to jump to the back of the vehicle and got out opening the back door. The remote/switch sometimes will lock and unlock all the doors, and the hatch, but will not the driver side door. …
