2007 Lexus Rx350. Consumer writes in regards to vehicle massive oil leak. On Tuesday January 20, 2015, while driving, the consumer noticed the rear windshield wasn't clear. When she activated the windshield cleaner, all it did was smear. She repeated the process three times, with the same results. Then, she noticed a burning smell. Upon proceeding through a traffic light, she heard an engine noise and was loosing acceleration power. The consumer decided to have the vehicle towed. When the tow truck driver pushed the vehicle out of the parking space, there was a huge puddle of oil where the vehicle had been parked. Then she noticed, the entire back, from the top to bottom was covered in oil. That is why the windshield fluid kept smearing . Once at the dealer, the consumer showed them the notification she received regarding the oil leak. However, the dealer stated the problem she experienced was not the problem that was covered. It was a different hose which had developed a hole causing the massive oil leak. The oil cooler pipe was replaced.

Driving on the highway my wife noticed a film on the back window as we were headed from onalaska WI to eau claire WI about 20 miles from eau claire the oil lamp started to flicker then came on solid. We also heard a flapping sound. We were not sure what was going on we stopped at a kwik trip gas station and checked the oil dip stick and noticed no oil. Also checked the back of the car had oil film purchased 4 quarts of oil and drove to the nearest quick lube they discovered a serious leak coming from a small hose off the oil filter area I am concerned we may have engine damage. Why were we not notified by Lexus?? thanks.

The engine makes a noise like a sloppy piston or a rod knocking. The car is a 2010 Lexus Rx350 with 69,000 miles. What is interesting here IA the fact that the issue was discussed with the service group on a recent confrence call but the staff was told to keep it quiet. Is Toyota playing the games again?.

2008 Lexus Rx350 engine noise started making noise at about 23,000 miles. The dealer said it was normal. Took it back in for the 30,000 mile check up and told them that it was getting louder. They checked it out again and said that it might be the mechanical fuel pump,but that was normal. This is starting to sound like a diesel and is getting a little embarrassing to drive around sounding this way. If this is normal, this will be my first and last Lexus. . . .
