A major safety concern arose when Toyota discovered the steering lock bar cracks, leading to a recall of 373,000 vehicles.
These models face multiple safety concerns, including power steering pump failures, worn steering racks, and rust issues in the steering shaft components. The lack of grease fittings makes the steering system particularly vulnerable to water damage and corrosion. If you’re considering these model years, be aware that repair costs typically range from $700-$950, and some owners report persistent issues even after repairs. Regular inspection of steering components is vital to maintain safe operation.
Critical Engine Problems to Watch For
Several critical engine problems plague specific Avalon model years, with the 2006 version standing out as particularly problematic due to catastrophic oil loss issues. You’ll need to watch for complete engine oil loss that occurs without warning lights, typically around 59,000 miles, leading to costly $2,000 repairs.
Ignition misfires affect multiple generations from 1995-2010 and 2012, causing engine jerking and hesitation. While faulty ignition coils are often the culprit, you’ll also need to check for malfunctioning control modules and fuel injectors. Like the steering column defects found in early Toyota Venza models, these issues require careful attention during pre-purchase inspections. The 2014 model presents another serious concern with sudden unintended acceleration, where RPMs spike dramatically from idle. Early 2000s models suffer from manifold melting and potential sludge formation, though engine replacements due to sludge remain relatively rare. Similar to Honda CR-V models from 2007-2011, excessive oil consumption can be a significant issue requiring close monitoring and frequent oil level checks.
Transmission Troubles in 2011-2014 Models
When shopping for a used Avalon, you’ll want to steer clear of the 2011-2014 models due to their widespread transmission problems. These years frequently exhibit transmission hesitation, particularly when shifting from second to third gear at low speeds. The issues typically worsen after 100,000 miles, with owners reporting daily occurrences of hard shifting.
Much like the costly repairs seen in 2013 Altima transmissions, these problems often require expensive fixes once warranties expire. A significant concern is the torque converter shudder, causing violent shaking at 20-40 mph when releasing the accelerator. While Toyota released software updates to address this issue, many vehicles still experience problems. Even more troubling are reports of sudden unintended acceleration, with RPMs jumping dramatically without driver input. Regular fluid changes haven’t proven effective in preventing these transmission failures, and complete transmission replacement is often necessary. Similar to the Nissan Rogue’s CVT transmission failures, these issues often lead to expensive repair costs for owners.
Interior Quality and Material Concerns
Beyond transmission issues, interior quality presents another compelling reason to avoid certain Avalon model years. You’ll want to skip the 2005-2008 models due to widespread dashboard cracking, deteriorating trim pieces, and poor design ergonomics. The cup holder design and poorly placed steering controls create frustrating usability issues.
The fourth-generation Avalons (2013-2018) also deserve scrutiny for their interior material durability problems. These models suffer from sticky surfaces, low-quality leather upholstery that deteriorates quickly, and cheap-feeling plastic components. Post-2011 models continue this trend with peeling headliners, brittle plastics, and synthetic leather that cracks prematurely. While these issues might seem cosmetic, they greatly impact the car’s long-term value and your ownership experience.
