What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
On august 29, 2017, while driving to arizona from california, the radiator cap failed causing the engine to overheat. I was stranded 90 miles north of the nearest town in 110-degree heat with substandard cell phone service. This overheating caused substantial engine damage which made the vehicle inoperable.
When starting my car, I noticed the smell of gasoline while sitting in the driver's seat. I knew something was obviously wrong. I took my car to the nearest auto shop where they troubleshot the gasoline leak to a fuel pressure pulsation damper on the fuel rail of the engine.
I rolled over to side of street, while noticing smoke coming from engine compartment on passenger side. Opened hood and saw a fire by engine wall. I had a couple of bottles of water with me. I pored water on fire and after one minute distinguested the fire.
My vehicle has been diagnosed with a faulty abs actuator. This has made braking hard, sometimes unresponsive, and disables the abs. I took it to the lexus dealership where this was confirmed and I was quoted over $4,000 to repair this issue.
