Open the full vehicle complaint log (all categories)I was driving on the freeway and my engine lost power and all the lights on my dashboard went haywire. I tried to get off the freeway but with the loss of power made it extremely difficult and dangerous. I thought I was going to get into an accident since my car slowed down so abruptly. I had to limp my way across traffic which was very scary. The car was jerking and shaking. I finally got to the side of the freeway and the car did not want to continue so I called for a tow truck and waited on the side of a busy highway. The tow truck brought my car to the Honda dealership which diagnosed the problem immediately as a blown head gasket. They said it was a known problem and the mechanic knew what to look for. They fixed the head gasket and I have my car back. My car only has 92k miles and I don’t think the head gasket should fail this early in the vehicles life. I properly maintain my engine with routine oil changes. There is no reason the engine should break down like this. I feel that there is a defect in Honda’s head gasket.
Mid October 2023, we driving on the freeway and the car started to slow down on its own. We could not accelerate to match the speed of cars around us or to get the speed limits in a 55 to 65 zone, making it dangerous for us and others to continue driving on the freeway at extremely slow/low speeds. We towed it the dealership, who said it was defective spark plugs. This car was only 4 years old with extremely low millage and the spark plugs should've last a lot longer. They changed the spark plugs under warranty. Late November 2024, we were getting off the freeway and the check engine light came on but there were no service codes. Everything was running normally except for the engine was making a loud noise. We parked at a shopping center and approximately 30 minutes later, restarted the car and all these messages and icons appeared for: Vehicle stability assistant system problem, Hill start assistant problem, ACC, Collision Mitigation breaking system problem, Road departure mitigation system problem, Emissions system problem, TPMS, Brake system problem, Electric power steering system problem. Towed it dealership and after an hour of diagnostics testing, they said it’s the spark plugs again! Just a little over a year and 2 out of 4 spark plugs are bad again. This is not right. We hardly drive this car and it’s only a little over a year since the spark plugs were replaced and a little over 5 years since we got the car brand new. Spark plugs are supposed to last 10 years or 100,000 miles and we’re not close to either. This time they said it's not covered under warranty and is over $800.
