Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists.

NHTSA ID 11634062 · filed Jan 4, 2025

I took my car to my mechanic for an oil change, and they noticed an oil leak at the timing chain cover, which could pose a safety risk, including a potential engine fire. They informed me this is a known issue on Toyota and Lexus vehicles with the 3.5-liter V6 engine. To confirm, I brought the car to a Lexus dealership, and they verified the same problem.

I've owned my 2014 Lexus IS 250 for over 10 years. I've almost always kept my car covered in a garage at work and at home, and I've never had a problem with the dashboard until now. Just last month (October 2025), my dashboard started melting and getting extremely shiny and sticky during the day - so much so that I can't see out my front windshield because of the glare from the shiny dashboard, making it very dangerous to drive. After my car is out of the sun for a while (like my garage), the dashboard eventually cools down and is no longer shiny or sticky. It has a cloudy, smudged look. However, once I start driving again during the day, the sticky, melting, and shiny dashboard returns. I've tried calling Lexus Corporate to assist with this serious safety issue, but they refuse to help, claiming my car wasn't part of the sticky, melting dashboard campaign. I am extremely disappointed with Lexus Corporate, as my family and I have been very loyal Toyota / Lexus customers for over 35 years. I've taken my car to my local Lexus dealer for inspection, who has confirmed the issue and provided me a quote to replace the dashboard for over $2,400. I hope Lexus Corporate would reconsider and do the right thing by replacing my faulty, dangerous dashboard.
