“Hello everyone -- I have 06 Lexus gs300. I had a rebuilt transmission, new valve six solenoids. Because I had harsh on the 2 to 1 downshift. That didn't fixed the problem, and they told me about the ecu the new computer will cost me $1550 on top of the $2200 I had to pay for the transmission and labor too. Their should be a recall notice. How can we alert Lexus of this problem and shift the cost to them for their repairs?”

“My vehicle head light flickers on and off. When it flickers out, if you turn the light switch off and on, it turns the light back on. The light may stay on or flicker back out without knowing. I had the light bulb replaced, costing $275.00 thinking that was the issue. Weeks later, I was notified by a random person the same light was out. Again, turning the switch on and off, allowed the light to turn on, but later flickering out and on. …”

“Car wouldn’t start. Had it diagnosed and found out my fuel pressure sensor had melted and was leaking fuel had it replaced bug still smell gas in and around car. Car was under recalm for same issue years back and was serviced at the dealership. So I don’t see how im liable for repairs if it was a problem when the car came off the assembly line”

NHTSA complaint #11443431, filed 2021-12

“This is extremely dangerous. My headlights keep going out. I've replaced the lamps and this wont fix the problem. I cant believe Lexus is letting this continue with such a major safety issue of having non working headlights. They go on and off at all times. I've got kids and im terrified to drive any time close to night fall with them in the car. I notice they are on then 5 minutes later they flicker off. I turn the switch on and off and they stay on for a bit then turn off again. This is a major safety issue and it looks like its affecting many of us. …”
