Lexus built the LX570 to last. But no vehicle is perfect, and this one has its flaws—expensive flaws. Owners assume these SUVs are bulletproof until a check engine light flickers on, coolant leaks, or a hidden oil leak turns into a $5,000 repair.
Would you know if your timing chain was about to fail? Would you catch an oil leak before it destroys your engine? Most drivers don’t. By the time they bring it in, the damage is done.
At Fremont Foreign Auto, we specialize in keeping LX570s running smoothly in Union City, Fremont, and beyond. Here are the five biggest problems we see—and what you can do to avoid costly repairs.
Timing Chain Stretch – A Silent Engine Killer
The LX570’s 5.7L V8 relies on perfect timing. If the chain stretches, it throws everything off. Fuel economy plummets. Power drops. The check engine light turns on. Ignore it, and you’ll be replacing more than a chain—you’ll be looking at a complete engine failure.
This is most common in 2008-2015 models. Once the chain stretches past its limits, you’re facing a $3,000+ repair bill if caught early. If you wait too long, it can total the engine.
At Fremont Foreign Auto, we use dealer-level diagnostics to catch early signs of chain stretch. We replace worn tensioners, adjust the timing, and install OEM-grade replacement chains designed for durability.
Waiting too long? That’s not an option.
Valley Plate And Cam Tower Oil Leaks – Hidden Damage Waiting To Happen
Most oil leaks leave a puddle under your car. This one doesn’t. The LX570’s valley plate and cam tower seals fail in 2008-2015 models, and the oil pools inside your engine bay. You won’t see it. You won’t smell it. But over time, it depletes oil levels, causes overheating, and destroys internal components.
Once the damage is done, repairs cost upwards of $5,000. The smarter move is to catch it early.
At Fremont Foreign Auto, we remove the intake manifold, track the leak, and install upgraded gaskets. We don’t just stop the problem—we prevent it from coming back.
Cooling System Failures – Overheating Means Game Over
LX570 owners assume overheating won’t happen—until it does. Radiator cracks, thermostat malfunctions, and failing water pumps are common in 2016-2019 models, and once overheating starts, it’s a countdown to engine destruction.
One instance of overheating can lead to warped heads, blown head gaskets, and a repair bill over $10,000. We’ve seen it happen.
At Fremont Foreign Auto, we pressure-test the entire cooling system, replacing failing components before they cause serious damage. We use high-performance OEM radiators, thermostats, and pumps to ensure your engine stays cool.
Waiting for a warning light—by then, it’s too late.
Starter Motor Failure – When Your Lexus Won’t Start
Push the button. Nothing happens. That’s how starter motor failure begins. It starts with slow cranking, then an occasional misfire. Eventually, your LX570 won’t start at all.
We see this often in 2010-2013 models. It can leave you stranded at the worst possible time.
At Fremont Foreign Auto, we don’t just swap out the starter. We check relays, wiring, and the battery system to ensure the fix lasts. We use high-quality replacements that restore reliability.
If your LX570 hesitates to start, don’t ignore it. Get ahead of the problem before it gets worse.
Heated Seat And Bluetooth Failures – Small Issues, Big Frustrations
The LX570 is built for comfort. But when heated seats stop working and Bluetooth connection issues make hands-free calls a nightmare, that comfort disappears.
We see this across 2016+ models. Heated seats fail due to wiring breakdowns, and Bluetooth malfunctions happen due to outdated software or hardware failures.
At Fremont Foreign Auto, we fix these tech issues with precision diagnostics and software updates. If necessary, we replace faulty wiring and modules, restoring your Lexus to its luxury status.
Don’t settle for a broken system. Fix it and enjoy your LX570 the way it was meant to be.
