Around the middle of the month of January of 2022, I discovered that my 2016 Lexus RX350 has massive oil leak from timing chain cover. Thompson Lexus dealership confirmed this oil leak. This leak not just happened, but it has happened long ago at least 6 months prior to the time that I discovered based on old oil dirty debris deposits and paints popped out and rusted caused by prolong oil on the frame. The reason that did not detect the oil leak right away was that I have almost not used the car at all for the past two years due to Covid situation. Second, I have parked my car on my lawn, so that could not see oil drops. Third, I put my trust on Lexus and Toyota products, so I have not inspected for oil leak periodically. This oil leak has soaked many parts of the engine, frame, electrical connections, and possibly other moving parts such pulleys and belts. This can potentially create smoke or fire hazard and belt and pulley slippery which can lead to accidents. At the time of the oil leak, my car was under 54,000 miles and under 6 years, so it was still under powertrain warranty with is 6 years and 70,000 miles. I have contacted Lexus several times regarding this matter. I told them about location of the oil leak and when oil started leaking, my car was still under powertrain warranty but Lexus refused to pay for the timing cover repair. After doing research on RX350 from timing chain cover, I have found out that a lot of Lexus RX350 has developed oil leak from timing chain cover since year 2009 or 2010 model to 2016 year model. Some RX350 developed timing chain cover oil leak from a few thousand miles of first use to 38,000 miles. Lexus was aware of the problem, but completely ignored and failed address the problem and issue a recall.

Auto bright head light system deactivates/reactivates indiscriminately, most frequently a few minutes after departing in the morning (still dark). Lack of proper bright light control while driving at night greatly reduces visibility making this a safety issue. I have provided video evidence to Lexus dealer demonstrating the problem who consulted with corporate Lexus; Lexus claims that they found my vehicle to be within Lexus specifications and has refused to further investigate nor repair. Information posted on the internet by numerous Lexus rx-350 owners reported the same problem - one suggesting that proper cleaning of the camera lens fixed the problem; I provided the evidence to Lexus and Lexus refused to attempt this solution. Following is Lexus guest experience center response; dear mr.: thank you for contacting the Lexus guest experience center.

This car experienced an unintended acceleration at the top of my driveway while being put into park. The car took off and hit the center posts of the two car garage and only stopped because it was caught on the supports in the foundation. We had experienced this sudden unintended acceleration several times during the first year we own the car when we were getting onto the highway. We did report it when we brought the car in for a service, they were aware of the complaint but at that time there was no remedy for the computer slash transmission issue. I was parking the car at the top of the driveway, my foot was going on to the break and the car unintentionally accelerated and flew through the air into the center post of a 2 car garage. I luckily was not physically injured but was emotionally distraught. It took down both garage doors and the center pillar all of which had to be rebuilt and replaced.

The contact owns a 2016 Lexus RX350. While driving various speeds, the vehicle jerked without warning. The vehicle was taken to Lexus of las vegas (6600 w. sahara ave, las vegas, nv, 702-942-6600), but the technician was unable to duplicate the failure. The failure recurred and the vehicle was taken back to the same dealer. The manufacturer was made aware of the failures and referenced tsb number: L-sb-0109-17 to the dealer. The technician resettled the transmission according to the tsb instructions. The vehicle was repaired. The failure mileage was approximately 500.

The transmission has three settings. In any of them, start up often results in erratic shifting, rough acceleration and sometimes abrupt lurching forward. This has resulted in alarming shifting and acceleration. The shifting from one gear to the nexr is not smooth nor contributes to safe start-up in my opinion - and I am over 80 and have driven many cars and trucks - worst shifting in my experience and is dangerous. Dealer says is normal.

Car has hesitation when driving. Car rated for unleaded not premium and should have not to drive car in sport mode all the time

- New Braunfels, TX, USA

When I try to accelerate from a stop, a loud groan can be heard from somewhere in the powertrain. There is also a vibration which appears to be coming from the transmission area of the vehicle. In addition, when travelling at highways speeds, during the acceleration process, a delay occurs from the time I step on the gas peddle until the vehicle accelerates. The hesitation is approximately 1-2 seconds.

I was at a stop light the car all of a sudden would no longer accelerate yet the car was in drive. I took it to the dealership and they can not replicate and so I am still driving the vehicle. Hoping it will not happen while driving.
