Driving a Toyota Avalon? Listen up. These luxurious sedans, while reliable, aren’t immune to problems. At Fremont Foreign Auto, we’ve seen it all. Our Fremont shop serves Milpitas and nearby areas, specializing in Asian vehicles like your Avalon. We’re here to break down the seven most common issues these cars face.
Did you know the Toyota Avalon shares its platform with the Lexus ES? This luxury DNA contributes to its smooth ride but also means some repairs can be more complex. Let’s dive into the problems you might encounter and how to fix them.
Oil Consumption Woes
2005-2009 Avalons are notorious oil guzzlers. Why? Faulty piston rings. They don’t seal properly, letting oil sneak into the combustion chamber. Blue exhaust smoke? That’s your cue. You might be adding a quart every 1,000 miles.
The fix isn’t cheap. Engine rebuild time. New piston rings, rod bearings, maybe even pistons. Toyota extended warranties for some affected vehicles. Regular synthetic oil changes help, but won’t solve it entirely.
Transmission Troubles
Shift and shudder. That’s what 2005-2007 Avalon owners with U660E transmissions often experience. The culprits? Worn solenoids or a degraded valve body. These parts control fluid flow. When they fail, shifting gets unpredictable.
Diagnosis is key. Solutions range from replacing solenoids to a full transmission rebuild. Don’t skimp on transmission fluid changes. Prevention is cheaper than cure.
Steering Rack Leaks
Power steering giving you grief? 2000-2004 Avalons often develop steering rack leaks. Cracked seals let power steering fluid escape. You’ll notice increased steering effort and maybe a pink puddle under your car.
The fix usually involves installing a remanufactured steering rack. It’s labor-intensive and requires precise alignment. Quality parts are crucial for a lasting repair.
Oxygen Sensor Failures
Check engine light on? Rough idle? Poor fuel economy? Blame the oxygen sensors. High-mileage Avalons, especially those over 100,000 miles, are prone to this issue.
These sensors measure exhaust oxygen levels. When they fail, your engine runs inefficiently. Replacement is straightforward but requires specific diagnostic equipment. We often recommend replacing sensors in pairs.
Water Pump Problems
Early 2000s Avalons can suffer from water pump failures. This part circulates coolant. When it fails, overheating follows quickly. Listen for a high-pitched whine from the engine bay.
Replacing the water pump is moderately complex. While we’re in there, we often recommend changing the timing belt too. Two birds, one stone.
VSC and ABS Glitches
2005-2012 Avalon owners, watch your dashboard. Vehicle Stability Control (VSC) and Anti-lock Braking System (ABS) warnings are common. Causes vary from faulty wheel speed sensors to ABS pump issues.
Diagnosing these problems requires specialized equipment. Fixes range from sensor replacement to overhauling the ABS unit. Don’t ignore these warnings. They affect your safety.
Sunroof Drainage Dilemma
Water in your Avalon? Check the sunroof. Drain tubes can clog or disconnect, leading to interior leaks. You might notice damp carpets or water stains on the headliner.
Fixing this involves cleaning or replacing the drain tubes. Regular sunroof maintenance can prevent these soggy situations.
