The Honda Accord is a benchmark for reliable midsize sedans - the K-series 4-cylinder is legendary. But the 1.5T turbo (2018+) introduced new issues, and certain years had transmission concerns. Here is what to expect.
The 2018-2020 1.5T turbo models have documented oil dilution complaints, especially in cold climates. The 2013-2017 K24 4-cylinder is the gold standard for reliability.
The 1.5L turbo engine can mix gasoline into the oil, especially on short trips in cold weather. Honda issued software updates and warranty extensions. Watch oil level - if it rises, that is fuel dilution.
Run free diagnosis →The 5-speed automatic behind the J-series V6 has a known failure pattern - harsh shifts, slipping, and outright failure between 80-120K miles. A class action covered some early years.
View P0700 Diagnosis →The CVT in the 1.5T can shudder under light acceleration. Most issues are resolved with fluid changes and software updates, but neglected fluid leads to premature wear.
Run free diagnosis →V6 Accords from this era are known for power steering pump failures - loud whining, especially on cold starts, and eventual leaks.
Run free diagnosis →The starter motor on the 9th-gen Accord is a common failure point around 80-100K miles. You will hear a single click or nothing when turning the key.
Run free diagnosis →The AC compressor clutch and condenser have an above-average failure rate on the 10th-gen Accord, often around 40-70K miles.

2003 (V6 transmission issues), 2008 (V6 transmission), 2018-2020 (1.5T oil dilution complaints - especially in cold climates)
2013-2017 K24 4-cylinder - arguably the most bulletproof Accord ever. 2021+ models have largely resolved the 1.5T oil dilution issue.
Routine maintenance averages $450-750/year. Expect one transmission service, one AC repair, and ignition components over 200K miles. Total non-routine: $3,500-6,000.

Yes, with caveats. The 2013-2017 K24 4-cylinder Accord is one of the best used cars under $20K. Avoid the 2018-2020 1.5T unless you can confirm Honda has performed the oil dilution software update and the car lives in a warm climate.
The 2015-2017 Accord with the 2.4L K24 engine is considered the most reliable. It avoids the 1.5T issues and uses Honda's most refined naturally aspirated 4-cylinder.
On the 1.5T (2018+): oil dilution and AC compressor failures. On older V6 models (2003-2008): automatic transmission failure. The K24 4-cylinder has very few common issues.
It is improving. Early models (2018-2020) had documented oil dilution issues, especially in cold climates. Honda extended warranties and pushed software updates. 2021+ models have far fewer complaints.
A K24-powered Accord (2013-2017 especially) routinely reaches 250,000+ miles with regular maintenance. The 1.5T is too new for full lifespan data, but well-maintained examples are running strong past 150K.
