The vehicle was driven by my [redacted] daughter and at @ 6 pm on [redacted] the engine was making a noise and that the car was starting to slow down and stall,so she called me. She pulled over and shut the car off and then all the dashboard lights started to blink really fast. The car started to smoke from the engine, she got out and called 911. 911 said they would send a tow truck. within a few minutes sparks were coming from underneath the engine and then the fire started. she called 911 and myself again to report the car was on fire. Thank God she was away from the car. The tow co. arrived first, then first responders, then myself. The highway was shut down to put out the fire. Our daughter was hysterical and the car is a total loss. We waited until the car fire was extinguished. The first responders offered medical attention, but she just wanted to go home. …
Vehicle started making loud banging noises. Took to local independent mechanic. He said the engine rod bearing is bad and vehicle is unsafe to drive and could cause an accident if completely fails while driving. The car is available at my house. Called Honda of Bartlesville when engine light initially came on with code for engine problem and when I showed up, the one I talked to on phone acted like I never called about it then hid in the back room and wouldn't come out. The car was 150 miles from end of warranty. To drive it there it was over warranty, and this was discussed on phone call. The car was inspected by local mechanic. The first sign was around 50K miles and periodically come on. The dealership wouldn't do anything about it and ignored it when I discussed it. Car now has about 100 miles and is sitting in my driveway as I try to figure out what to do with it. …
Teenage daughter was driving in rush hour traffic and the car seemed at have stalled out. She pulled over on the shoulder and manually turned off the car. When she tried re-starting it, it would not start. Electrical came on, but no power to the engine. Something then seemed to have overheated because when fire department was called, they extinguished something that had melted the plastic covering underneath the car. Fire department called due to smoke. No flames seen. We believe the smoke was from the melted plastic under car from something (a fluid) that was leaking. Insurance was called, car was towed to a Honda repair shop and then towed to a local Honda dealership. They say engine seized and is locked up and will not re-start. Other noted repair needed they say is torque converter. No other problems with this vehicle in the past. One of the best cars we have owned. …
