“I PURCHASED A USED 2007 LEXUS RX350 FOR MY 16 YEAR OLD DAUGHTER. IT HAD A LITTLE OVER 100K MILES. EVERYTHING WORKED PERFECTLY, NO COMPLAINTS WHATSOEVER. UNTIL, MY SON BORROWED IT, AND WHILE HE WAS DRIVING IT, HE SAID IT QUIT. HE LOST ALL POWER STEERING, SO HE PULLED OVER. WE CALLED A TOW TRUCK TO TOW IT TO A MECHANIC. WHEN THE MECHANIC CALLED ME, HE SAID THE OIL COOLING LINE BUSTED, WHICH MADE THE OIL PUMP EMPTY THE ENGINE'S OIL. HE SAID IT WOULD NEED A WHOLE NEW ENGINE. HE SAID THE CAR IS WORTH NOTHING. I PAID $9K FOR THIS CAR A YEAR AGO, AND NOW IT IS NOT WORTH $100. THE MECHANIC SAID THIS IS A KNOWN PROBLEM FOR TOYOTA/LEXUS, BUT THERE WAS NO RECALL. TO ME - THIS IS UNACCEPTABLE. IN MY OPINION, SINCE TOYOTA KNEW OF THIS PROBLEM, BUT DIDN'T RECALL IT, THEY EITHER NEED TO COVER THE COST OF A NEW ENGINE, OR BUY THE CAR BACK FROM ME. I AM VERY UPSET OVER THIS.”

“I saw on the internet while I was looking for new mats this year my Lexus RX 350, 2007, vin [XXX] was recalled for the dashboard until May 2017. During 2013 through 2018; my husband left me for my friend; both my sons were shot in different cities; one in Nashville, and one in Denver Colorado. The one in Nashville, was shot 10 times by his roommate who forgot he had a roommate. Fortunately, he turned around so his laptop in his backpack got the bullet which would have killed him. He was left with a dominant disabled arm. He had just come back from Las Vegas working with Jason Aldean as a cameraman and saw the bloody massacre from the shooters. My oldest lives in Denver. He was shot and killed by the police on a domestic call. They overreacted. My ex-husband would not let me come to the funeral or visit the son in Nashville when he was hurt. I was not able to focus on anything else during that time. When I saw the recall on the Internet this year, I called and requested a reprieve. I was turned down. I wrote a letter to Lexus. Again I was turned down. I am [XXX] and [XXX]. I’m still driving my Lexus 2007 and plan to the rest of my life. I didn’t see the mail…”

“Electrical system malfunction began (to my best calculation & recollection) in summer 2021 with the first of four battery malfunctions in one year. Each time, AAA discovered low battery response and recommended battery replacement. This time around, battery was replaced about two weeks prior, due to battery failure/AAA reporting would not accept charge. THE NEW BATTERY FAILED (8/3) and the starter broke while attempting to charge. Mechanic repaired starter and battery accepted the charge. No problem, right? Wrong. This driver drove about 30 miles and while driving, the electrical system shut down altogether. With I believe ALL WARNING LIGHTS LIGHTING UP, extremely dangerous situation. NO BREAKING, NO STEERING, NO WARNING. Fortunately, it occurred in a suburban residential area as opposed to the highway. SECOND tow to my mechanic and now, after a full week, no diagnosis, though the car has been running in the shop. This is an intermittent problem. I suspect the alternator.”
Air bags
28 reports4 crashes
“The contact owns a 2007 Lexus RX350. The contact stated that over time she noticed that the dashboard was cracking and separating. The contact was concerned due to the proximity of the passenger’s side air bag housing and the crack in the dashboard. The contact was also concerned about an inadvertent deployment without the vehicle being involved in a crash. The local dealer was contacted and informed of the failure but offered no assistance. The vehicle was not repaired. The manufacturer was not contacted or informed of the failure. The approximate failure mileage was 113,000.”

“ON SEPTEMBER 18,2019 @~12PM WHILE PARKING MY 2007 LEXUS RX 350 DRIVING AT VERY LOW SPEED <5 MPH THE VEHICLE SUDDENLY ACCELERATED HOPPED A CURB AND I WENT INTO THE ROAD. THANKFULLY I DIDN'T CRASH OR HIT ANYONE. MILEAGE AT TIME WAS 52549. I READ ON HERE OTHER PEOPLE HAD SIMILAR ISSUES. I DIDN'T SEE ANY RECALLS FOR THIS PROBLEM ON MY VEHICLE. MY FLOOR MATS ARE NO WHERE NEED THE GAS PEDAL. THE MATS ARE LOCKED IN PLACE BY THE PIN. THEY DON'T MOVE. I PLAN TO TAKE THE CAR TO LEXUS DEALERSHIP. THEY MUST BE AWARE OF THIS ISSUE.”
Electrical system
20 reports
“Put key into ignition port and heard and felt a klunk. Key was then freely moving and connecting to nothing inside the ignition chamber. So vehicle would not turn over at all. Had towed to town closer to home. And Currently having towed to mechanic shop for further evaluation. The only symptom the car was having previously was a mysterious scratching sound coming from what sounded like the right side of the hood near the firewall. Took to mechanic and he drove the car and heard the sound but could not pin point it, said nothing was scrubbing the fan or anything else he could see. And to bring it back if it got worse. Never did we think it was the starter nor the ignition chamber. The only way to know now....is to replace it and see if that noise is still there. There were no other warnings. The danger in this is being stranded. Still needs to be evaluated by mechanic.”
