Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Issues exist with the navigation screen/unit. Climate control is run exclusively through this unit, and when the unit fails, there is no way to control the climate in the car. With this said, the windows can fog up and impair visibility. This is a common issue with these vehicles.”
NHTSA complaint #11040893, filed 2017-10, 145,000 miles“The car like many push button start cars requires that you step on the brake pedal when starting, but the car will not start sometimes and/or requires a lot of force on the brake pedal to start the car which is apparently due to the brake booster going bad. This has been happening intermittently over the course of the year or about 9000 miles. …”
NHTSA complaint #10554667, filed 2013-12, 48,000 miles“Vehicle was stationary and sat overnight. Upon starting car srs light came on and was diagnosed with trouble code DTC 1861 that resulted in a knee squib malfunction due to a wiring harness issue. This requires a new wiring harness that will cost over $2500. Lexus knows this is an issue as they have issued a TSB for it but refuses to issue a recall or do it as a goodwill service. This is a major safety issue especially due to Lexus realizing there is an issue but refusing to step up and correct the issue.”
NHTSA complaint #11072463, filed 2018-02, 141,000 miles“There is a known issue with the vehicle wiring harness for the 2006-2008 wiring harness resulting in a fault with the airbags. Lexus has issued a technical service information bulletin for this issue (l-sb-0167-08) however no recalls have been issued. This fault causes the airbags to fail and not deploy in the event of an accident. .....updated 12/03/15 updated 8/23/2017”
