Does the 2019 Honda Accord still have the 1.5T oil dilution problem?

Yes. The 2019 Accord 1.5T retains the oil dilution issue documented in the 2018 model. Honda issued additional software calibration updates, but the problem persists in cold climates. Owners should have oil tested for fuel contamination.

What is the most common failure on a 2019 Honda Accord?

CVT transmission shudder and failure is the most expensive common complaint, costing $3,500–$5,200 to repair. A/C compressor failure and electrical sensor issues are the next most common.

Has the 2019 Honda Accord factory warranty expired?

Yes. The 3-year/36,000-mile bumper-to-bumper warranty expired by 2022 and the 5-year/60,000-mile powertrain warranty expires by 2024 for most 2019 Accords. Owners should consider extended warranty coverage now.

Is the 2019 Honda Accord a good car to keep long-term?

Yes — the 2019 Accord is a refined second year of the 10th generation with resolved early production issues. With an extended warranty in place, it can be reliably driven to 200,000 miles with manageable costs.

2019 Honda Accord Extended Warranty: What 2019 Owners Need to Know

2019 Honda Accord Extended Warranty: Common Issues, Repair Costs, and Coverage

The 2019 Honda Accord continues the 10th-generation platform with the 1.5T and 2.0T engines. Honda issued software updates to address the 1.5T oil dilution concern that appeared in 2018 models, but the underlying cold-weather risk remains on some vehicles. At current mileage, 2019 Accord owners should be aware of CVT reliability, A/C system wear, and electrical component failures.

Key Takeaways

1. 1.5T oil dilution risk reduced but not eliminated — verify Honda software update was applied
2. CVT longevity: shudder, hunting, or hesitation can indicate early CVT degradation
3. A/C compressor and expansion valve failures: $1,200–$2,200 average
4. Infotainment system issues: touchscreen and Honda Sensing calibration faults are reported
5. Factory bumper-to-bumper warranty has expired; powertrain coverage may be nearing end
6. Deluxe or New Car Coverage recommended to cover electrical and A/C systems alongside powertrain

Frequently Asked Questions

Is the 2019 Honda Accord 1.5T still affected by oil dilution?

Honda issued updates for the 2019 model year to reduce oil dilution risk, but owners in cold climates who take frequent short trips should still monitor oil quality. Confirm with a dealer that your vehicle received the latest calibration update.

What transmission does the 2019 Accord use?

The 1.5T uses a CVT (continuously variable transmission), while the 2.0T uses a 10-speed automatic. The 10-speed automatic is generally more durable but more expensive to repair at $4,000–$6,500.

More Resources

The 2019 Honda Accord is the second model year of Honda's 10th generation, and in many ways a more polished version of the 2018 redesign. Honda addressed some early production concerns, but the 1.5T oil dilution issue and CVT concerns carried forward. By 2026, a 2019 Accord is 7 years old with approximately 85,000–115,000 miles — right at the inflection point where major repairs become statistically probable.

Quick Answer

The 2019 Honda Accord is a refined 10th-gen model, but the 1.5T oil dilution issue and CVT transmission problems ($3,500–$5,200) persist. Factory powertrain warranty is expiring or has recently expired. Now is an important time for 2019 Accord owners to secure extended warranty coverage. Athena offers plans with a $100 deductible.

Key Takeaways

1The 2019 Accord's 1.5T oil dilution issue persists despite Honda's software updates — cold-climate owners are most affected.
2CVT transmission shudder and failure remain the most expensive potential repair ($3,500–$5,200).
3Factory powertrain warranty is expiring or recently expired for most 2019 Accord owners.
4At 85,000–115,000 miles, the 2019 Accord is entering its highest-risk repair window.
5A/C compressor and Honda Sensing sensors are additional common failure points.

2019 Honda Accord: 10th Generation, Refined

For the 2019 model year, Honda carried over the 10th-generation platform with minor refinements — upgraded Honda Sensing standard features, improved infotainment responsiveness, and some suspension tuning adjustments. The powertrain lineup remained the same: 1.5T with CVT or 2.0T with 10-speed automatic.

The 2019 Accord received strong reliability ratings in early surveys, but the 1.5T oil dilution concern that emerged with the 2018 redesign was not eliminated in the 2019 model year. Honda's software fix mitigated but did not resolve the underlying issue in cold climates. Additionally, as 2019 Accords accumulate mileage, CVT wear is becoming increasingly common.

Known Issues Specific to 2019 Honda Accords

1.5T Oil Dilution (Ongoing)

The 2019 Honda Accord 1.5T carries the same oil dilution risk as the 2018 model. In cold climates — particularly states with sustained below-freezing temperatures — fuel can enter the crankcase and dilute oil. Honda's TSB-19-025 calibration update reduces frequency but does not eliminate the issue.

Long-term oil dilution causes:

Accelerated engine bearing wear
Cylinder wall scoring
Turbocharger bearing degradation (from thin, diluted oil)

Engine rebuild or replacement costs range from $3,000 to $7,000+ depending on the extent of damage.

Consumer Reports noted the 2019 Accord's 1.5T received below-average engine reliability scores in owner surveys, driven primarily by oil dilution complaints. The 2.0T scored significantly better for engine reliability in the same surveys.

CVT Transmission Shudder

The 2019 Accord 1.5T CVT experiences shudder during light acceleration — typically between 15–40 mph — related to belt slip and clutch pack wear. Honda's CVT fluid update resolves shudder in many cases early in the vehicle's life, but at 80,000+ miles, mechanical CVT wear requires more invasive repairs. Full CVT replacement costs $3,500 to $5,200.

A/C Compressor Failure

The 2019 Accord's A/C compressor is a common failure point shared with other 10th-gen Accords. Compressor replacement costs $900 to $1,500. If the compressor seizes and sends aluminum shavings through the A/C system, total repair including condenser replacement and system flush can reach $1,800 to $2,400.

Honda Sensing Radar and Camera Malfunctions

The 2019 Accord's collision mitigation braking and adaptive cruise control radar (mounted behind the front grille) can malfunction due to calibration drift, physical damage, or internal failure. Radar replacement costs $1,200 to $2,500. Camera replacements run $400–$900 plus recalibration.

An ongoing class-action lawsuit (Whitaker v. American Honda Motor Company), filed in the Northern District of California, alleges Honda knew of the 1.5T CVT's shudder defect prior to the 2018 redesign launch. The suit covers 2018-2021 Accord CVT models, including the 2019. Honda has not issued a formal CVT recall, but TSBs with revised fluid specifications and software updates have been issued and remain available at no charge while the powertrain warranty is active for affected vehicles.

Factory Warranty Status for 2019 Honda Accords

3-year/36,000-mile bumper-to-bumper — expired by 2022
5-year/60,000-mile powertrain — expiring or expired by 2024
8-year/150,000-mile emissions warranty (limited)

Most 2019 Accord owners are now fully outside factory powertrain coverage. This is a critical window to secure extended warranty protection before a major failure occurs.

Typical Repair Costs for a 2019 Accord at Current Mileage

CVT replacement (1.5T): $3,500–$5,200
10-speed automatic rebuild (2.0T): $2,800–$5,500
Engine internal repair (oil dilution damage): $3,000–$7,000+
Turbocharger replacement: $1,800–$3,000
A/C compressor + system: $900–$2,400
Honda Sensing radar: $1,200–$2,500

Recommended Coverage Tier for 2019 Honda Accord

Deluxe Coverage — Covers CVT, engine internals, turbocharger, A/C, electrical, steering, and suspension. The best all-around option for 2019 Accord owners facing the post-factory-warranty gap.
New Car Coverage — Near-complete protection including ADAS sensors. Strongly recommended for 1.5T owners who have documented oil dilution history.
