2022 Honda Accord engine problems

“Vehicle: 2022 Honda Accord Hybrid Sport (VIN: [XXX]) Dealer: Rauli Auto Import LLC (Paterson, NJ, License [XXX]) Odometer at Sale: 141,836 miles Description of Severe Safety Defect and Resulting Accident: On October 16, 2026, this 2022 Honda Accord Hybrid was purchased from a used car dealership. The vehicle was delivered to the consumer with severe, pre-existing, and undisclosed braking system defects that made the vehicle an immediate safety hazard on public roads. On [XXX], just days after taking delivery, the vehicle was brought to an independent, licensed mechanic (Mega Auto Diagnostic Inc., Invoice [XXX]) due to severe handling and braking concerns. Following a certified inspection, the licensed technician officially documented catastrophic pre-existing safety failures on the vehicle. The mechanic certified that the vehicle had an active engine leak, completely failed front brakes, and completely worn-down rear brakes and rotors. The dealership sold the vehicle in a hazardous condition without performing mandatory safety inspections. Days after the mechanic's diagnosis, while attempting to park the vehicle, the pre-existing braking system failure caused a…”

“The head gasket failed in the engine. Coolant leaked into the cylinder head causing the engine to overheat and put the driver at danger to immediate vehicle failure while driving. The problem was confirmed by the dealer. The vehicle has only been inspected by the dealership. There were warning lamps that indicated engine overheating.”

“The car suddenly started to miss fire and lose power. This puts the driver and others in dangerous situations. If it happens when pulling out into traffic and the car misfired it could cause a serious crash. Honda service diagnosed that a blown head gasket causes coolant to leak into the cylinders, leading to engine misfires and a sudden loss of motive power at highway speeds. This issue is well documented on 2016 to 2022 honda Accords. There are many documented cases of this exact premature failure. Honda is aware of this issue and has awarded some owners goodwill repair when outside of warranty. There is currently ongoing litigation because of the 10s of thousands of head gasket failures. My car has 75k miles and went out of warranty at 60k miles. My goodwill request was denied by local regional Honda Rep but I elevated the request to corporate Honda and currently waiting on their response.”

“I am writing to file a complaint regarding a serious issue with my Honda vehicle involving the turbocharger system. The turbocharger appears to be failing, causing a significant reduction in vehicle speed and performance while driving. During operation, the vehicle suddenly loses power and acceleration, making it difficult and potentially unsafe to maintain normal traffic speeds. At the same time, multiple warning lights illuminate on the dashboard, indicating possible engine and system malfunctions. This issue creates a serious safety concern for both myself and other drivers, as the vehicle may unexpectedly slow down while traveling on highways or busy roadways. The condition has negatively impacted the reliability and dependability of my vehicle. I am requesting that Honda investigate this matter promptly and provide assistance in diagnosing and correcting the issue. If this problem is related to a known defect, recall, service bulletin, or warranty extension, I would appreciate being informed immediately.”

“I am submitting this complaint regarding an apparent head gasket failure involving my 2022 Honda Accord Sport 1.5T equipped with Honda's 1.5-liter turbocharged engine. At approximately 143,000 miles, I began experiencing coolant loss without any visible external leak. I also noticed rough operation and shaking during startup. Concerned about the symptoms, I consulted a Honda specialist who advised that the vehicle is exhibiting signs consistent with a failing head gasket and will likely require head gasket replacement. This vehicle has been meticulously maintained and serviced throughout ownership. I retain maintenance records and have taken exceptional care of the vehicle. There has been no abuse, neglect, overheating event, or failure to maintain the vehicle. Through my research, I have found numerous reports from owners of Honda vehicles equipped with the 1.5-liter turbocharged engine describing similar symptoms, including coolant loss, startup misfires, rough cold starts, coolant intrusion into cylinders, and premature head gasket failures. The consistency of these reports suggests a possible design or manufacturing defect affecting the durability of the…”

“While driving my vehicle suddenly would not accelerate above 20 mph and warning lights all over the dash lit up (check engine, abs brake system, adaptive cruise control, vehicle stability, power steering, hill assist, and brake hold). I took it for a diagnostic, it gave a code for cylinder 3 misfire. I got a tune up the next day along with a fuel system cleaning just to be safe. After about 35 miles of driving I had the same issue 2 days after the tune up, this time no warning lights. I took it back to the shop and this time the spark plug in cylinder 4 was bad. I believe I am at the beginning of what many others have complained about with these same symptoms. This problem makes operation of my vehicle unsafe and uncertain, at any time this issue can kick in and now you are limping along at 20 mph while cars zoom all around you. While trying to get the vehicle to the shop I created traffic buildups and was almost hit multiple times due to the vehicles diminished acceleration.”
