The contact owns a 2008 Lexus RX350. While starting the vehicle, the contact heard a grinding noise under the hood. The noise was only present for a few seconds, especially in cold weather. The manufacturer was notified of the failure and informed the contact that the camshaft sensors were failing. The vehicle was not repaired. The failure mileage was unknown.

While driving on city street in madison wi, severe oil loss due to hose to oil cooler. Part was changed by manufacturer from rubber hose to metal. This tells me they know it is a problem. Dealership in madison wi says they get this repair weekly.

Following a routine oil change at my Lexus dealer, the car exhibited an oil leakage while driving on the highway. The car's engine began smoking, a burning smell was noticeable, and the rear windshield was covered in oil. The view through the rearview windshield was not visible. The car engine made some strange noises and it was difficult to drive the vehicle. Residual engine damage is possible, and an accident was luckily avoided. The dealer claimed that there was a recall on the vehicle for this problem, and that they would extend the warranty of the vehicle and replace the oil cooler. Some research online yielded some conflicting information. Many different customers have experience this problem, but no recall was ever issued. T.S.B. pol-14-02 (NHTSA number 10056509) was issued in July 2014 to fix this dangerous defect that puts drivers at risk, when a recall may have been warranted. We were never notified by Lexus or the dealer that this was a potential issue. Thousands of Toyota and Lexus owners may have faced or will face a similar risk in the near future.

While driving my 2008 Lexus RX350 at 35 mph in heavy traffic, the vehicle suddenly stalled leaving me without power steering or brakes. I was able to stop the vehicle but was stuck in the traffic lane with heavy traffic. Fearing that I would be hit by oncoming traffic I called 911 for support while the tow vehicle was dispatched. I was unable to leave the vehicle safely until police arrived 20 minutes later, due to the position of the vehicle and the traffic. The local Lexus dealer has contacted me to let me know that the issue was a broken valve spring caused the engine to seize while running. I am concerned that this condition may be somewhat of a known issue with Lexus as I have seen that they had problems with valve springs breaking in this engine.

While driving to work heard a funny noise and oil light begin to blink. Found out engine oil cooling tube burst and leaked all the oil out and has caused motor damage. Lexus send a warranty enhancement letter just a few weeks before describing a problem with the tube and that they would inspect and repair. Waiting on Lexus customer care to assist. So far only 25%. looks like a class action lawsuit may entail.

We have complained about a noise upon starting the car for the past year when having the vehicle serviced. This was the first service visit where dealer was able to pinpoint the code and they came back with the cam shaft variable valve timing (vvt) gear issue. The repair estimate was $6830. I found your recall dated September 4, 2013 # 13V395000 for vvt on Lexus GS350, IS350 and is350C models for the same model year and find it suspicious as the same engine is used. I am wondering if other rx 350S have the same issue and the recall should actually be expanded to include the RX350 model. At this point, the dealer says they need to tear the vehicle down to accurately assess if it is the bolts or another issue but the expense is very high. I also was wondering what the range of miles were on the recalled vehicles? thank you for looking into this.

RX 350

  • 65,000 miles
At 65,000 miles vehicle had a major breakdown. Serpentine belt ruptured causing fire and smoke inside the engine compartment and both inside the cabin and outside. Gas pedal became inoperative and vehicle had to be towed to a repair facility. As further determined the cause of the belt rupture is the A/C compressor freezing stuck. Repair is extremely costly. Parts alone are close to $1500. Lexus is not willing to help in any way and all of the maintenance per the maintenance booklet is performed and on time. Additionally the maintenance booklet does not require any work other than filters, oil changes until 100,000 at which time only spark plugs are mostly due to be replaced. A/C compressor should not have gone out at 65,000 miles on a 2008 Lexus.
