Owner-reported complaints naming the engine system, filed with NHTSA
Data refreshed
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components. Every record below is an owner-reported complaint about the 2024 Honda Accord submitted to NHTSA — not a confirmed defect, not a recall and not a manufacturer bulletin. 10 reports on file name it.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

The engine vibrates/shutters when switching from electric to gas. It almost feels like the engine is going to fall out. I’ve taken it to two different Honda dealerships multiple times and since they can’t duplicate the issue while it’s there then they say there’s nothing they can do. The oil also looks and smells like gas.
The contact owns a 2024 Honda Accord. The contact stated that while driving 50 MPH, the instrument cluster lights illuminated. The message “Emissions System Power Reduced – See Dealer” was displayed. An unknown transmission message was displayed. The engine was not working properly. The message "Pull Over and Turn off Vehicle" was displayed. The contact pulled over for 10 minutes, restarted the vehicle, and continued to drive to the residence. The local dealer was contacted, and a service appointment was scheduled. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.
I am formally reporting a catastrophic engine failure involving the 1.5L turbocharged engine in the current-generation Honda Accord. As a professional high-mileage driver, I am exposing a severe design defect that poses immediate safety risks. While driving on the highway, the vehicle suddenly exhibited severe engine shuddering, a sudden loss of acceleration, and a dashboard overheating warning. A certified Honda dealership inspection revealed a severe head gasket failure, confirming that engine coolant is actively leaking into cylinders 1 and 3, causing critical engine misfires. This is an inherent manufacturing defect, not normal wear. The engine runs under extremely high thermal pressures, and the factory head bolts fail to maintain a proper seal, allowing coolant to breach the combustion chamber. The safety implications are critical. A sudden loss of power and engine stalling at highway speeds forces drivers into high-risk emergency situations, drastically increasing the likelihood of collisions. Furthermore, the constant loss of coolant leads to sudden engine overheating, creating a severe fire hazard. This exact issue plagued the previous 10th-generation Accord, and it is now clear that Honda failed to implement a permanent engineering fix for the current generation. Representatives from Honda Corporate have explicitly acknowledged to me that a manufacturer recall for this exact engine defect is currently under internal consideration. Because high-mileage vehicles reach the structural threshold of this component much faster than the average consumer, this case represents an early warning sign of a widespread, recurring failure. NHTSA must initiate an immediate safety defect investigation into the current Honda 1.5T engine powertrain to prevent catastrophic highway accidents and protect the public.
This vehicle is on its 3rd set of injectors within a year. It is a known problem that Honda knows they keep replacing them but they keep going out causing a misfire
Yesterday, January 30, 2026 as I was driving (approximately 30mph) my car seized, came to a stop, dashboard lit up with multitude of words/symbols. After approximately 15 seconds I was able to use the gas pedal and the car drove. My safety was at risk, this sudden stop jolted me hard. If there was another vehicle behind me I would have been hit. The warning messages were so quick and cleared away with seconds that I cannot recall. I drove to my local dealer and the battery cables were checked and ok. I scheduled an appt for Monday Feb. 2nd as this was Friday. On January 21st this local dealer replaced my battery, after months of "computer glitches" that were never resolved with two dealers and 4 dead batteries.
UNKNOWN I was not advised or informed of any recall
Within 48 hours of taking possession, the vehicle suffered a blown head gasket, a catastrophic mechanical failure that constitutes a pre-existing latent defect—a serious condition that existed prior to the sale but was not disclosed to me. This defect renders the vehicle unsafe, inoperable, and unfit for its intended use. Claims that I did not purchase the optional 2-day cooling-off period or that the vehicle is covered under a manufacturer warranty are legally irrelevant. Under California Civil Code §§ 1791.1 & 1792 (Implied Warranty of Merchantability), a dealer is obligated to sell a vehicle that: 1.Is safe and operable at the time of sale 2.Is fit for ordinary driving purposes 3.Does not contain major latent defects that make the vehicle unsafe, inoperable, or unusable immediately after purchase The presence of a pre-existing latent defect is a direct violation of these provisions. The manufacturer warranty does not excuse the sale of a vehicle with a defect that existed at the time of purchase. I am therefore demanding, without delay: 1.Immediate rescission of the sales contract by Raceway Nissan 2.Full refund of all funds paid, including deposits and trade-in credits 3.Coordination with Valley Strong Credit Union to fully rewind the auto loan, including principal, interest, fees, and any other charges 4.Confirmation that I will have no financial obligations related to this purchase once the rescission is completed
My car started shaking like it didn’t want to go. My engine light came on. Then it showed road departure mitigation system problem, collision mitigation system problem, adaptive. Those control problem, and emissions system problem then says engine is not functioning properly.
