Which Avalon years have the most problems?
Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Overwhelmingly positive sentiment regarding long-term reliability, comfort, and value, particularly for used examples. The Avalon is consistently praised as a durable, spacious, and smooth-riding sedan capable of exceeding 200,000 and even 400,000 miles with r
Transmission shifting behavior/concerns (2019+ models): Reports of sluggish acceleration, RPM flaring to 1500-2000 before shifting, delayed or non-smooth shifts, and owner concerns about long-term reliability of the UA80 8-speed automatic. Frequency: recurrent.
Electrical system failure (Hybrid models): Isolated but severe incidents of complete dashboard warning light illumination and system failure, leading to lengthy repair times and part delays. Frequency: isolated.
Oil consumption (Older 4-cylinder Toyota engines referenced, not Avalon-specific): Mentioned as a known issue for some Toyota models, but not specifically cited for the Avalon's V6. Frequency: N/A for Avalon V6.
Rodent damage to wiring: Knock sensor wire damage due to soy-based wire insulation attracting rodents, causing rough shifting and limp mode. Frequency: isolated.
Known maintenance items for older generations (e.g., 2007 model): Timing cover oil leaks, rack and pinion seal failure, VVTI oil cooler line failure, and transmission case sealant failure. Frequency: isolated (specific to detailed owner report).
