Check engine light came on on highway. Within a few miles, the hood began to smoke, so immediately pulled over. Towed to mechanic and was told water pump failure caused engine to overheat. Engine is destroyed.

While driving in my neighborhood, I heard a noise. 1-3 minutes later, the oil light came on. I went straight to the dealer (a mile away), despite the owner's manual indicating no urgency. They said my oil cooler line blew, leaked out all my oil and destroyed my engine within minutes. I came to find out later that this catastrophic, engine-destroying oil line rupture is a known defect to Lexus (like the vvt line) but for some reason was never recalled despite it being just as catastrophic/dangerous. Lexus chose to use a cheaper rubber hose instead of a metal pipe when the rubber hose can't take those high temps and will blow. 100% likelihood this will happen'just a matter of when. I researched it and there are millions of Toyota and Lexus cars affected by this problem'every single '07-'11 Rx 350 plus many Toyota. Lexus was made aware of the defect but chose not to fix it. Except in Canada, there was a mandatory recall and this part was replaced. For some highly suspicious reason, this didn't happen here. Why" it's dangerous enough to recall in Canada, but not the us" instead of recalling, us Lexus issued an insufficient 36 month warranty to replace it, but only if it blew during this time. If it didn't leak within that time, you're screwed. Lexus messed up its VIN tracking system, so people were not made aware of this warranty. For those who were, the issue was downplayed as simply an 'oil seep' instead of an oil line explosion which destroys the engine. Customers were not told at the dealership. We should have been alerted to the defect so we could fix it proactively and spare us the death of a car with only 90K miles. Google this problem to see the thousands of posts/complaints on Toyota/Lexus websites. There needs to be a mandatory recall and/or reimbursement for those whose engines were destroyed by Lexus' known defect. Please take action! please.

When I drive at above 60 mph, there is a rattling sound. I took it to the dealership and they are unable to pinpoint the issue even after removing the roofrack, the roof insulation and tightening all the bolts. I have found numerous postings online but Lexus still refuses to let us know the issue. Please help! it is very concerning that a loose part might cause major accident or event death. forums.edmunds.com/discussion/7588/Lexus/rx-350/Lexus-rx-350-rattles us.lexusownersclub.com/forums/topic/67986-2010-rx-350-has-noisy-interior-rattles/ community.cartalk.com/discussion/2117891/rx-350-Lexus-rattling-noise see photo. www.clublexus.com/forums/rx-second-generation/337671-annoying-clattering-noise-above-left-ear-of-driver.html

Shortly after buying the vehicle used (one previous owner), upon cold start a loud rattling noise could be heard coming from the engine area for about 30 seconds. Took to a Toyota/Lexus dealership for routine oil change, vehicle inspection, and asked the technicians to also address the noise. We were told that they couldn't reproduce it, and that it shouldn't be a problem. Driving down the freeway in greater milwaukee, the car stopped functioning. After visiting a local mechanic, then later resorting to a Lexus dealership, found that the vvt bolts had fractured. All of this is exactly as outlined in NHTSA campaign 13V395000. Now we have a dead luxury SUV due to an engineering problem, but Lexus will not provide any resolution to their known problem, even with physical evidence (photos, and failed parts still in hand).

Our vehicle has always been serviced at the local Lexus dealership and maintained in excellent condition. Without warning, on 3/5/14, as we were exiting the freeway, we smelled a slight burning odor. The oil light then flashed intermittently. We immediately took the vehicle to the Lexus dealership. We were informed there was only 1 quart out of 6 quarts of oil remaining. The rubber oil cooler lines had exploded, but we were assured there was no damage to the engine. The cost of repair was $400+. 1 week later, we heard a clicking sound from the engine. The dealership asked if we could make an appointment 5 days later. We insisted it be inspected that day. 3 days later we heard back that the engine had significant damage as a result of the rubber oil cooler lines exploding, and that it would cost $2,800 to diagnose, and between $3,800 to $5,800 to repair. We filed a claim with Lexus customer service due to the low miles on the vehicle, even though we were technically out of warranty. The dealership apparently told Lexus corporate that the vehicle would actually cost $12,000 to $14,000 to repair. The best Lexus corporate offered was reimbursement for the replacement of the rubber oil cooler lines. This is concerning for a number of reasons. Upon doing some research online, these particular oil lines made of steel and rubber have failed for dozens upon dozens of Lexus/Toyota customers. A very similarly designed rubber oil line for the vvt-I has already been quietly recalled by Lexus. Lexus no longer uses these materials for oil lines. We expected our vehicle to last well into 200,000 miles, but this was simply unacceptable. In the end, since we could not pay for the ridiculous repairs, we essentially were forced to trade it in for cash from the Lexus dealership. Please make Lexus/Toyota do a recall on these parts before someone is hurt or killed.

RX 350 6-cyl

  • Automatic transmission
  • 128,800 miles
Transmission started to slip on my Lexus rx 2007 AWD while accelerating from 20 mph. Engine revs but the car cannot speed up. Traffic backed up behind me. Fortunately, the incident happened close to our house. I could slowly reach home. I had it towed to the dealership where it was determined that the transmission need to be replaced. I always go to the same dealership for regular maintenance. I have all service records up to date. I had the automatic transmission flush done at 108,000 miles. Since then, I researched several online forums for similar issue pertaining to V6.

Now I recently had engine failure one month after transmission failure. To make matters worse, I was informed that my transmission is leaking. This problem was discovered after engine failure and replacement transmission.
