Four problems related to car stall have been reported for the 2007 Lexus RX350. The most recently reported issues are listed below.
The contact owns a 2007 Lexus Rx350. While driving 45 mph, the vehicle stalled without warning and was towed to an independent mechanic. The vehicle was towed to a local dealer (metro Lexus, 13600 brookpark rd, cleveland, OH 44135) where it was diagnosed that the cooling pipe needed to be replaced. The vehicle was not repaired. The manufacturer was notified and opened case number: 1801240854. The failure mileage was 129,827.
While sitting at a stop at engine idle, the check oil indicator light flashed followed by a short rough idle. The vehicle was pulled over and parked and a phone call made to the local Lexus dealer. It was advised to have the vehicle towed to the dealership due to the nature of the warning. The vehicle was towed to the dealer ship. Upon inspection by the service department at the Lexus dealership, the oil cooler hose had exploded causing a loss of engine oil. At the writing of this note, information was shared that indicated a newer version of the oil cooler hose would need to be installed. Any potential damage to the engine would have to be accessed after the replacement of the hose and clean-up of the under carriage of the vehicle and insulation surrounding the underside of the car was completed. After researching this topic, we are hopeful Lexus will share in the expense of this repair since it has been documented that similar failures have occurred.
The car completely halted while driving on a city road. The steering locked and the car completely stopped in the middle of the road. The manufacturer inspected the car. During inspection they found a/c compressor locked up causing vehicle to stall under load. Once the a/c system is activated, vehicle will stall out. They also confirmed that this could happen while the vehicle is in motion on a highway going 60 mph and if it did, it would stall the car and lock up the vehicle just like it did in the first incident. It seems completely unreadable to stall a vehicle in motion for some confirm/convenience feature like a/c. I feel this is a fundamental engineering problem with the way the car is designed. I would like to ensure this is declared as an issue with the design of Lexus vehicles and there is a trigger to disconnect ac under such circumstances where ac can stall a car in motion.
This complaint is regarding the vvt-I oil hose on a 2007 Lexus Rx350. Either the current rubber hose or the "improved" rubber hose with Lexus service campaign (9lh) doesn't address the safety concern about this hose. This hose routes a high pressure flow of hot engine oil outside the engine block. Rubber deteriorates over time and miles and can unexpectedly break or rupture causing engine oil to rapidly drain from the engine. Despite denials by Toyota/Lexus, this is in fact a safety issue because ruptured oil lines can and have cause accidents and fires when seized engines and/or oil soaked tires and/or brake pads cause loss of vehicle control and/or motorists to become stranded (possibly out of cell phone range). I have contacted Lexus to put the correct fix of all metal oil line which it began installing in Toyota/Lexus vehicles manufactured during April 2008 and Lexus refused to do so. I strong urge NHTSA to initiate an investigation on this issue due to the safety concern.
