The contact owns a 2012 Lexus ES350. The contact stated while driving approximately 65 MPH, the key was detected, and trunk open warning lights illuminated. Additionally, the doors would lock and unlock independently. The vehicle was taken to a local dealer where it was diagnosed with needing the trunk latch replaced. The vehicle was not repaired. The manufacturer was informed of the failure and agreed to cover the cost of the partial repair. The failure mileage was approximately 55,000. The VIN was not available.

All 4 doors stopped locking by key fob, inside switches or exterior door handle switches or when putting the transmission in gear. No click is heard when trying to lock doors but clicking is heard when hitting the unlock switches. Doors will unlock electronically/ electrically when they are manually locked from inside the vehicle. A previous report indicated a similar problem that a dealer diagnosed as all of the door locks needed replaced, which makes no sense that the could all fail mechanically at the same time. The problem appears electrical in nature and is dangerous since doors can't be locked when the car is in motion or in a safety situation where locking the doors could prevent intruder entry.

The horn quit working. Found it works only when the steering wheel is turned close to end of clockwise and counterclockwise direction. Deemed safety hazard since no horn sound to alert pedestians, bicyclists and other drivers of danger. Wasn't covered under warranty and cost $690 to replace steering wheel clock spring.

Takata recall and electrical failures. Lexus recalled vehicle in Jan 2017 warning that no one should sit in front seat for duration. No provision for a replacement vehicle was mentioned. It has been 10 months of not being able to use front seat. They say the parts will be available in December. Our vehicle is also getting my wife stranded. We have gone through 3 batteries in 3 years. Lexus refuses to fix it. Please reference attached recall letter. I was not able to attach the complete set of docs with detailed description due to file size.

I had a 2012 Lexus ES 350 and had problems with it. The first problem occurred when I was parking. I was angle parking and had my foot on the brake when the car jumped into a brick wall. Four air bags exploded in my face and rendered me unconscious. I was taken to the hospital in an ambulance. I could hardly walk and my legs were extremely swollen and I had many other bruises. The second incident was that the passenger seat of the car went on fire and burnt the seat. I feel I should not have to pay the final excess wear and tear bill of $829.50. In fact I believe I should be reimbursed for the last payment of $455 since the car was not in my possession. I had returned it to wilde Lexus of sarasota on March 16, 2015 as I was extremely concerned about the safety of the vehicle.

The contact owns a 2012 Lexus ES350. The contact stated the person driving saw smoke starting to emit from under the passenger seat, after the seat heater was activated. The vehicle was taken to the dealer. The technician found a small burn hole on the left side of the driver seat. The manufacturer was notified of the failure. The failure mileage was 15,200. Updated 2/24/15 Lexus informed the consumer, the burn hold was not located near the seat heater grid or where the electrical wiring was located and therefore, they would not cover the repairs.

On the passenger side dashboard next to temperature control switch, dashboard vinyl is melting, it has bubble and one bubble was broken to make a hole. I noticed it on April 1, 2014. When I changed the cabin air filter on March,31 in glove compartment, I didn't see it. I brought my car to new country Lexus and described the issue hoping that their technician may see issue with temperature control resistance may causing wiring to heat that is causing vinyl to melt. But they didn't see it that way, instead they are saying that I might have dropped a chemical on it, I swore to them I didn't use any chemical and I don't have any passenger except my wife. I don't want to fix the vinyl until I fix what caused it. But, unfortunately Lexus dealerships trained technician didn't see anything causing it from the inside the dashboard. By taking second opinion from outside repair shop, he mentioned the temperature control resistance may be heating up the wire that might have caused the vinyl to melt. I feel that this is a real issue and it may cause a fire. I have opened a case with Lexus corporate and a case manage promised to call me by April 4, 2014. Updated 04/17/14
