2019 Toyota Avalon Reliability Report

Owners report several issues with the 2019 Toyota Avalon, particularly concerning the vehicle's electronic systems and air quality. A recurring problem involves the Bird's Eye system and backup camera, which display a "black screen" when reversing or using the forward camera, especially under adverse weather conditions like snow or rain. Additionally, multiple owners describe malfunction alerts for the blind spot monitoring and cross-traffic alert systems, often occurring in cold or wet conditions, with no resolution from dealerships. Another common complaint is a persistent, unpleasant odor from the air ducts when the AC is set to recycle cabin air, noted around 35,000 miles. These issues, particularly those affecting visibility and vehicle alerts, may have safety implications, as they compromise driver awareness and response capabilities.

Owners of the 2019 Toyota Avalon frequently report issues related to a fuel system recall, with multiple complaints indicating delays in recall repairs due to parts unavailability. Common symptoms described include vehicle stalling without warning and rough running at various speeds, sometimes accompanied by the check engine light. These issues are reported at mileage ranges from 10,000 to 40,000 miles. While no crashes or fires are mentioned, the stalling and hesitation while driving could pose safety risks. Used car buyers should be aware of these potential issues and check the recall status and repair completion for this model year.

Owners of the 2019 Toyota Avalon frequently report issues with the vehicle's headlights, specifically noting inadequate illumination when driving in low light or total darkness. Complaints describe the low beam headlights as failing to project far enough to detect pedestrians or parked vehicles, especially on uneven roads, with one owner mentioning a projection limited to approximately 1.5 car lengths. Another common issue involves headlight discoloration, impairing nighttime visibility. These problems are noted at mileages as low as 4,500 and up to 14,000 miles. Safety implications are evident as owners express concerns about reduced visibility, which could pose a risk while driving at night.

Owners of the 2019 Toyota Avalon report issues related to the blind spot monitor and rear cross traffic alert systems. Complaints frequently mention malfunction alerts for these systems, with specific references to error codes C1AB4 and C1AB5. Some owners indicate that the sensors are not positioned correctly, leading to persistent problems. A service bulletin exists for this issue, but owners report mixed experiences with dealership support, with some being required to pay for repairs out of pocket. These issues are reported without specific mileage ranges, and no direct safety incidents such as crashes or loss of control are mentioned in the complaints.

Owners of the 2019 Toyota Avalon report issues with the vehicle's adaptive cruise control system. Commonly described symptoms include the cruise control failing to disengage when the brake pedal is pressed, and the car braking suddenly and unexpectedly while driving with the adaptive cruise control engaged. These incidents occur both on highways and city streets. One owner reports a collision with a truck due to the system's failure to disengage, while another mentions multiple instances of unexpected braking. There is no specific mileage range reported, but the incidents are noted over a span of three years. These issues may have safety implications, including potential collisions or loss of vehicle control.

Owners of the 2019 Toyota Avalon report issues with the suspension, specifically noting problems with vehicle stability while driving. Complaints frequently mention the car rolling or feeling unstable when cornering on uneven or bumpy roads, with one owner attributing improved performance to replacing the original tires. Another common issue described is the vehicle wandering or drifting on freeway surfaces, even after a wheel alignment check confirmed alignment was within specifications. These stability issues are noted at low mileage, as one complaint involves a new vehicle. While no crashes or loss of control are reported, the described wandering and rolling could potentially impact safety.

Owners report two distinct engine-related issues with the 2019 Toyota Avalon. One complaint describes excessive oil consumption in a newly purchased Avalon XLE with a V6 engine, requiring the addition of two quarts of oil by 2,000 miles and triggering a "low oil" light at 3,100 miles. Another issue involves the hybrid model's keyless ignition system, where the car can remain silently on when parked, potentially leading the engine to start unexpectedly to recharge the battery, posing a risk of carbon monoxide buildup in enclosed spaces like garages. Safety implications are noted in the hybrid model, with the potential for carbon monoxide exposure due to the engine starting without warning, and the lack of an immediate software fix for existing vehicles.
