Which issues does the Lexus ES 350 have?
Here are some of the most typical Lexus ES 350 issues, especially for the problematic model years, 2007 in particular. Although these are the most frequent difficulties, that does not imply that they are widespread.
Melting Dashboard
Similar to other 2007 Lexus vehicles, this one has some difficulties with the dashboard and other inside plastics. The plastic on the dash of the 2007 Lexus ES 350 can actively melt in the sun, which is one of the car’s worst issues and a major reason why 2007 is one of the Lexus ES 2007 years to stay away from.
It’s problematic for a number of reasons. One reason is because a melted dashboard is unsightly. Additionally, it may impair the performance of any dash-mounted equipment, such as your car’s airbags and interior electronics.
Additionally, melting plastics can create harmful VOCs that could harm consumers and contribute to the situation.
GPS Failures
Another frequent complaint about the Lexus ES 350 is that the GPS stops working, but thankfully this problem is not as serious as the melting dashboard. Early iterations of the GPS system had a few problems, however more recent models have fewer faults with the technology.
Oil Leaks
Additionally, there have been occasional allegations of excessive or unexpected oil leaks in the Lexus ES 350, particularly in older generations. Unfortunately, oil leaks and oil consumption are only some of the issues with the ES 350’s engine. More newer models don’t appear to have as many issues.
Miscellaneous Engine Problems
Avoid the Lexus ES 350 model years because they have a number of other engine difficulties, such as gasket and seal issues, ticking and banging noises, and other internal engine problems.
These issues range in severity and root reasons; some don’t significantly affect customers, while others call for expensive, urgent fixes.

Windows Opening On Their Own
This final common issue is a problem, but it’s not as big of a problem as some of the other problems we’ve spoken about. In specifically the early years, the Lexus ES 350’s windows and moonroof occasionally opened by themselves.
Most of the time, even after mistakenly opening, the windows and moonroof can still be closed. Nevertheless, depending on the weather outside, the traffic situation, and how shocked the drivers are when the windows open on their own, this could pose a safety issue.
