Recently reported ENGINE problems on 2007 Lexus RX 350

The oil cooling line in my well maintained 2007 rx 350 blew apart without warning, causing all oil to be lost from the engine and catastrophic engine damage totaling thousands of dollars were it to be repaired. this is apparently a very common, well known issue in the 2007 era rx 350 due to lexus' choice to use a rubber cooling line. this occurred with no warning whatsoever.

On my drive to work this am my engine started making a loud noise, i lost almost all of my oil in less than a mile. my oil cooler pipe busted. no warning or anything. left me stranded on the roadside. if i would have drove it any further it would have costed me an engine. the oil light flashed on and off and my car sounded like a tractor. no warning.

Tl* 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.

Lost engine oil driving 20 minutes to work. lexus dealer advised there is a common problem with the oil cooler line, there is a campaign within 10 years of first use. they won't replace it unless leaking; otherwise you are allowed to drive until the line blows causing catastrophic engine damage. a $60 part ends up being an engine replacement; nevermind the potential danger of an engine freeze at 65 miles an hour.

I purchased a used 2007 lexus rx 350 from carmax in september of 2014. the car has been at the lexus dealership 4 times already for rattle in back of car, ignition switch replacement, oxygen sensor replacement and 80,000 mile service. this month (august 2016) the care began to make a rattle just after starting the engine. upon contacting my local lexus dealership, i was told that the sound i am hearing is the vvt gear which will need replacing. the estimate given to me was $4k. what makes this even more interesting is that my husband owns a 2009 toyota highlander. his vehicle makes the exact same noise upon starting the engine. he too was told that he needed the vvt gear replaced for a cost of $6k which was only the labor portion. after reading complaints with the 2007 lexus rx 350 and knowing that lexus issued a recall on certain 2008 lexus models for this very issue tells me that a new recall should be made before someone is injured or death occurs. very disappointed in lexus.

Tl* the contact owns a 2007 lexus rx350. while driving approximately 5 mph, the low oil warning indicator illuminated and the vehicle was no longer operable. the vehicle was towed to the lexus dealer where it was diagnosed that, due to the wrong engine oil cooling hose being installed, the part exploded and the motor needed to be replaced. the manufacturer was notified. the failure mileage was approximately 124,000.

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. http://forums.edmunds.com/discussion/7588/lexus/rx-350/lexus-rx-350-rattles http://us.lexusownersclub.com/forums/topic/67986-2010-rx-350-has-noisy-interior-rattles/ http://community.cartalk.com/discussion/2117891/rx-350-lexus-rattling-noise see photo. http://www.clublexus.com/forums/rx-second-generation/337671-annoying-clattering-noise-above-left-ear-of-driver.html

2007 lexus rx350. consumer writes in regards to vehicle massive oil leak. *smd 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. *jb

As i was driving to work at night i noticed to engine got very loud, i pulled over noticed bluish-white smoke coming from engine, engine oil light finally came on. got out the car noticed a stream of oil behind the car. my car was still under extended warranty at this time. i immediately turned the car off when i seen the smoke. i left the car there. i contacted the lexus dealer of mt kisco which refused to come and get the car so i had the car towed at my expense, to their dealer. received a phone from dealer that day that the car was fixed, representative would not tell me what was wrong with my car only that it was covered under warranty and was rude! i found out later the next day the oil cooler line leaked out which i found out on this site this has been a problem with the rx350. and they kept telling me the engine was not damaged. received the car back, engine was not right, now the lower part of the engine had to be replaced! received the car again ,within a week noticed a sound coming from the engine, dealer picked car again and they put in a camshaft! before this incident, i never had a problem with this car, it was the best car i ever had, now, it is a nightmare! at this present time, the car is leaking again!! it looks like oil! *tr

Tl* the contact owns a 2007 lexus rx350. the contact stated that while driving 55 mph, the vehicle started making a loud noise from the engine compartment. the vehicle was taken to the dealer. the technician diagnosed that the vti oil hose had melted and the engine needed to be replaced. the manufacturer was made aware of the failure. the vehicle was not repaired. the failure and current mileage was 68,000.

Lost power on highway my rx350 (2007) lost power going 65 mph on a highway, and began to slow down quickly. with a truck on one side and another barreling down my behind, i tried to accelerate but the vehicle began to shudder and shake violently! by some miracle, i managed to swerve to the shoulder across 2 lanes, and avoided getting hit by inches! got the vehicle to the lexus dealer and they found out that it was a premature ignition coil failure - the vehicle has only about 42000 mi on it. asked lexus corporate to: 1) do a full investigation so as to prevent similar life threatening safety failures, and 2) reimburse the cost of repair at a minimum lexus customer service responded with a verbal offer to bear 10% of the cost of repair - and no promise of any investigation! talk about adding insult to injury. we'd undergone a traumatic event, almost losing our lives - my wife had started screaming on the side of the highway and would not get back into the vehicle! i refused, of course, and paid the entire (and substantial) bill myself. i'd like all readers to be aware of the power failure and be especially careful out on the highway. also be aware that the lexus promise of perfection seems to be mainly lip service nowadays - safety apparently is not in their definition of 'perfection'. to see such a serious incident being treated so trivially was totally at odds with the lexus mission and the lexus promise to its drivers. *tr

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).

Check engine light came on and vsc off came on while driving. vehicles vibrate violent shortly after. was diagnosed by lexus technician that ignition coil #6 has failed. *tr

I own a 2007 lexus rx350. when starting my car, a grinding sound is heard coming from the engine every 1 out of 7 or 8 times. the performed a diagnostic test, and the dealer advised that the camshaft tower would need replacing. apparently this is a common problem with the year, make, and model. the failure mileage was 89,000. lexus said they woulc cover parts but not labor, labor is 2/3 of the cost (total estimate $3800). apparently the car is unsafe to drive as is. *tr

Check engine light came on and vsc off came on while driving. this is the second tine in 2 months. vehicles vibrate violent shortly after. was diagnosed by qualify technician that ignition coil #6 has failed. this is similar to previous check engine light on problem 2 months ago when ignition coil #4 failed. *tr
