The vehicle has been maintained consistently.  Starting in early October 2026, the vehicle began shaking violently under acceleration while the engine was cold, including when accelerating at highway speed and climbing hills. The shaking lasted for roughly the first 15 minutes of every drive. No check engine light or diagnostic trouble codes appeared.  In mid-October 2026, a Honda dealership diagnosed coolant leaking past the cylinder head gasket into the combustion chamber and quoted approximately $5,000 for the repair. Replacement parts are on backorder with no estimated arrival date.  Violent shaking during highway acceleration is a safety concern, and continued coolant leakage into the cylinders can cause further engine damage.  In August 2026, American Honda extended head gasket warranty coverage to 10 years or 150,000 miles on 2018–2022 Accord 1.5T and hybrid models for the same condition: coolant entering the combustion chamber and causing misfires. The 2.0L turbo engine was excluded. A pending class action (Alcantara et al. v. American Honda, consolidated with Bissell v. American Honda, S.D. Cal.) alleges head gasket failure in Honda's 1.5L and 2.0L turbocharged engines.  I ask that NHTSA investigate head gasket failures in 2018–2022 Accords with the 2.0L turbo engine, and whether this engine should be included in Honda's remedy.","products":[{"type":"Vehicle","productYear":"2018","productMake":"HONDA","productModel":"ACCORD","manufacturer":"Honda (American Honda Motor Co.)"}]}]}
