Engine And Engine Cooling Problems of Lexus RX - part 1

When removing foot from gas pedal the rpm shoot up to almost 4k instead of switching to ev mode or dropping to 1k rpm’s. This has scared my wife causing her to slam on brakes as she thought throttle was stuck since the rpm’s shot up. This is dangerous. It doesn’t happen all the time and Lexus did duplicate it but said was normal.

3 months before the accident the power steering light came on twice and went off. The day of the accident the brake light came on when I started the car that day. It disappeared when I was put in drive. I was entering onto the highway to merge with the traffic. Another car waiting for the light to turn green so he could enter also. My car didn’t stop because my brakes failed and the collision avoidance system didn’t work either. No sounds nor warnings. I have photos of the message that was displayed on the dashboard. Tried sending photos but it didn’t work.

The contact owns a 2025 Lexus Rx350h. The contact stated that while coming to a stop, the brake pedal and accelerator pedal were both depressed simultaneously. The contact stated that there was a loud sound coming from the engine compartment. There was no warning light illuminated. The contact forcefully depressed the brake pedal to stop the vehicle. The vehicle was towed to the dealer but was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 119.

When we purchased this car in June 2024 it did not have an engine revving issue. The engine, electrical or transmission maybe all of them have serious safety issues! when driving and you let off the gas pedal the engine starts revving very loudly, it scares the heck out of you because you don't know if you can stop! I have a serious mechanical background, there is always the possibility of the transmission not disengaging and forcing the car not to stop! this issue is very dangerous and scary! we get very nervous driving a car we paid almost 70k for! yes reported to the dealer mungenast Lexus of st. Louis, yes they have duplicated the issues. After keeping our car now on two different occasions for weeks at a time they went to Lexus engineers who are now trying to say its normal! if so, why didn't it start doing the revving until there were thousands of miles on the car! this is a cover up! not been inspected by the manufacturer yet, they only spoke with them. No reason for police or insurance yet. No, there has never been a check engine light appear. The only other thing the car did, after the first time of it revving like this it died when we were pulling out in traffic, it didn't die it actually shut off! this has only happened the one time, it shutting off, can it do it again you bet! these cars are dangerous, I hope nobody has to die to prove this!.

1. Engine timing cover leaking 2. Oil could leak out emptying which could cause the engine to stop working at any given time 3. Problem has been confirmed by hennessy Lexus dealership in duluth, GA but they will not fix it. 4. Vehicle has been inspected by the dealership 5. No signs, I found out from the dealership after taking it in for an oil change.

From what I have been reading on that year and model, there seems to be major issues with the invertors. Like many I was driving on the highway and the vehicle just quits. This put me and many others in a very dangerous situation and I could have been hit at high rates of speed. If as many people are having these issues, then Lexus needs to step up and recall this part before someone gets killed.

Timing cover gasket leak. Apparently this is very common problem with 2016 Lexus Rx 350 due to a bad design by Lexus. Lexus is quoting ~7000 to fix.

When I start to coast to come to a stop the engine will rev, even though the energy flow screen shows the gas engine is disengaged and running only on ev. The engine will rev, even with me using the brake. But the ev light is off and the rpms are rising. Eventually the ev light will come on and the gas engine will cut off and the vehicle will switch to ev mode. My mpg has dropped to 36. 2, so something is not right. When I was at the dealer for my 10k service, they told me this was the car "shedding" the extra energy, but the battery was not fully charged, so I'm perplexed and frustrated.

Vvt-I oil line failure. Limited service campaign ended in Dec 2021. No notice sent, no repairs suggested at the dealership within the eligible period. Vvt-I failed and engine lost all oil in minutes while driving, coating the front passenger brake caliper and rendering the breaking dangerously difficult on the passenger side on the highway.

When I was driving down the road there have been times that I smelled smoke and was concerned my car was on fire. I checked the oil and inspected around my car, and didn't find the source. Today when I took my car in for service I found out the source of the smoke has been for the past 4 months. There is engine oil leaking from the timing cover that I was informed by my Lexus dealership today would cost $7,000 (approximate) to fix. I researched online and found that all vehicles with this particular engine are known to have this problem, and it is fairly common. Leaking oil can be a fire hazard, and it seems unacceptable that Lexus/Toyota let this issue continue without addressing it with a recall. Thanks for your time, and I have also sent a similar letter to Lexus also to let them know of my concern.

Below is the email that I sent to both the manufacturer and the dealership: I hope your christmas eve was better than mine. My son and I were driving up to the poconos christmas eve to go skiing and I noticed the sonar detection light come on. When we were driving back from the poconos, the transmission would not catch around the second or third gear. The rpms would shoot up. The dash / warning lights lit up. I pulled over to the side of the road and I called Lexus dealership, service center, and road side assistance. However, due to the fact that it was christmas eve, the offices were closed. I managed to make it to my parent’s home, but it was a very dangerous ride on rt. 80. The odometer stated that we were going 50 mph, but we were crawling and the rpms were 4000. The rpms at rest were always over 1000. Additionally at times, the gear would not shift into second or third and/or bottom out. Obviously the transmission is beyond malfunctioning. Below are pictures including: 1. ) check your engine: a malfunction in the electric control of the engine, throttle or automatic transmission has been detected. . . 2. ) a malfunction in the intelligent clearance, sonar system has been detected 3. ) traction control turned off 4. ) secondary collision break system malfunction, 5. ) system malfunction 6. ) drive-start control malfunction. The vehicle has just over 3000 miles. I am beyond distraught. My phone number is (908) 625-9277. However, I think it's best if we communicate through email at this point. I planned a family ski trip to killington, vt for the new year. I would like to request a loaner vehicle so I can salvage this holiday. I look forward to hearing from you and your service department.

The power steering and hybrid system failed and vehicle completely stopped in middle of busy freeway with no prior warnings or issues before. The safety of my son and I, and others around me during the abrupt stop of the engine. I could not move out of way. The vehicle has been serviced for this exact issue during a recall campaign lasting from 2011 to 2014. Ten years later and it is still happening! there were no warning lamps or messages or symptoms prior to this failure. It just passed vehicle inspections for the year.

For some unknown reason the car will suddenly display multiple warning lights, check engine, service needed, traction control off/inactive then the car will go into reduced engine power mode which prevents acceleration and causes the car to feel like it’s going to stall or shut off. This has happened several times on major high speed highways causing other cars to slam on their breaks, drive recklessly to avoid my failing car. My daughter has been in the car several times when this happened and it took everything in my power to not collide with another vehicle. We have taken the car to the Lexus dealership every time and they have tried to fix the car over a dozen times but it keeps happening. They don’t seem to know the issue or cause, trying several different solutions. How can a car manufacturer not know what is wrong with their own car not how to fix it? what am I supposed to do, just keep driving it and pray an accident never happens? there is no warning when this happens and no way to keep the car from swiftly decelerating or keep the car from using “minimal engine power” which I’m to,d is to protect the engine but I’m more worried about us. The date below is for the most recent incident.

The the vvi oil line failed in April of 2024. Contacted Lexus corporate via phone and problem was never resolved. Fast forward to November 2024 and after paying to have vvi oil line replaced the motor failed on the highway. Mechanic said complete engine failure. This car was a certified used Lexus and they failed to replace the vvi during the certification process! prior to buying this used car from an individual I called hendricks Lexus 6935 w frontage rd, merriam, KS 66203 and spoke to service advisor willie who said if you have any problems with that vehicle bring it in and Lexus is making good on the hybrid vehicles. After purchase I went to hendricks 9300 NW prairie view rd, kansas city, mo 64153 multiple times for parts and service history. I spoke to parts manager, service manager and several others and not one person informed me of the problem and immediate need for concern! how did this car get certified prior to the previos owner buying the vehicle “certified”? I bought this car with the understanding that it had been completely certified and given the 6 year additional warranty to the owner I purchased it from, although they were still considerably below the miles guaranteed with the certification. How did Lexus allow this vehicle to pass the certification without replacing a $100 part that could result in catastrophic failure. This car was sold at a premium because of the certification, yet a part that had been reconfigured and identified as contributing to a catastrophic failure as early as 2012 was left on the vehicle!.

Engine cut out suddenly while driving 45 mph, followed by battery light, check engine light, and power steering light forcing hazardous emergency stop. Engine would no longer crank, and car had to be towed to nearest Lexus certified repair facility. Technician scanned the system and found four codes: p0335, p1603, p1604, p1605. After bore-scoping front three cylinders, technician tried to turn motor by hand and was unable to. The motor turned in reverse, but not forward. Technician removed oil pan to find pieces of valve spring broken and pieces of the piston rings and piston fragments from one of the rear three cylinders. Motor will need to be replaced or completely rebuilt after only 133,458 miles and regular servicing.

I pulled onto a 4 lane divided highway and the car immediately went into limp mode, meaning the car would not go more than 1 mph even with the gas pedal to the floor. I could not accelerate thus my safety was in danger, and I was almost hit by a tractor trailer truck. I pulled over to the side of road as best I could, then shut the engine off and restarted the engine. This apparently re-set some sort of engine control and then the car accelerated normally. The dealer applied an ecu update #24lc03. When I researched this update, it was stated that this was not an actual recall, I wondered how that could that be since I was nearly involved in a fatal accident, and surely there are other similar Lexus owners at the same risk . That I was. The wording of the update described exactly what happened to me. In my opinion this information is too important to shoved under the rug and not made into an actual recall. A life could be saved. Thank you for looking into this.

The vehicle hesitates off a full stop such as at a red light. The automatic start stop feature is turned off manually, but car hesitates off the stop creating an unsafe condition if making a left turn where there is no left traffic arrow turn signal and cars are coming in the opposite direction or when entering a moving lane. The hesitation is enough to prevent you from entering or crossing moving traffic unless you wait for all traffic to be gone. This only happens when it is hot outside. When it is cool and air temperature is lower this does not occur and the car operates as normal. Has happened since new and dealer cannot look into it because there are no failure codes appearing on the car's system.

It has the same engine failure problem as the recall for 2022 and 2023 vehicles. The engine just stalls when it wants with no check engine light or error codes. Then restarts just fine when put in park. Lexus repair could not even find a issue. Have documents to prove it.

My car has an oil leak from the timing chain cover gasket that was discovered by an independent mechanic at 37,465 miles. The dealer confirmed the leak on June 14, 2024 during a recall replacement of the fuel pump. The repair is very expensive and the car is no longer under warranty. This is the second occurrence of this same issue. The first occurred in April 2021 at 24,192 miles and was repaired by the dealer under warranty. There were no warning lamps or messages of the problem but there was oil on the ground where I park. The car is available for inspection. An internet search confirms that this is a known and common problem with the Lexus Rx350 (and specifically the 2017 model) for many owners with some occurring more than once as in my case.

Timing chain cover oil leak is a wellknown issue for Lexus/Toyota v6 engine for more than a decade. The company is still reluctant to provide a long term solution. This 2016 Lexus Rx350 f sport was first discovered timing cover oil leak at 49166 miles and was resealed on Jan. 27, 2021. One year later, on Jan. 13, 2022, valve cover gasket oil leak was found at 57608 miles. Two months later, on Mar 16, 2022, timing cover oil leak was discovered again at 58821 miles. Then two months later, on may 16, 2022, oil leak was discovered again at 59864 miles. [all above was repaired by thompson Lexus in doylestown, PA under Lexus powertrain warranty. ] now, two years and 15000 miles later, the car is currently developing the same oil leak again at 76500 miles. The car is out of warranty, the repair will cost $7000. Toyota/Lexus should provide a lonterm sustainable solution for this problem instead of advising repairshop to merely reseal the cover, which will eventually leak again.

Codes p219c & p0301 have continuously came on , these lights mil have made the vehicle go from awd to 2 wheel drive while in motion. 4/25/2024 vehicle was taken to bay ridge Lexus. In brooklyn NY. They over looked this issue and stated it was something else. This has been confirmed via multiple diagnostics machines. Lexus of edison has also decided not to cover this repair under warranty . The danger of going from 4 wheel drive into 2 wheel drive while in motion is extremely dangerous . These warning lights/mil once activated has also caused the vehicles sonar to fail cause a serious safety issue. My vehicle is available to be inspected as needed.

The contact owns a 2023 Lexus Rx350. The contact stated that on three occasions while driving at various speeds, the vehicle lost motive power for approximately 20 seconds, and then accelerated as needed. There were no warning lights illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 4,200.

My 2011 Lexus Rx350 was running fine as I ran errands for groceries and other items around town one day. Then, out of the blue, I realized that after returning home and parking in my garage, there was a trail of oil in my driveway, leading to my vehicle. I looked under the engine area and noticed a pool of oil. I had a certified mobile mechanic come to my home and provide a diagnosis. This diagnosis was that a hole had formed in the rubber engine oil cooler line, and drained nearly all the oil in my engine. He mentioned that one more mile and I could have had total engine failure. He proceeded to replace it with a new genuine Lexus, all metal oil cooler line. I contacted Lexus about this incident, but they provided no compensation for this occurrence, even though there was a short 4-year technical service bulletin they issued barely a year after production, that called out this was indeed a flaw in their design. After doing some research, I see this is a very common issue, with many in the past most recent years having this very issue. Yet, Lexus has not recalled this, nor reimbursed those that have suffered from this manufacture defect. I am really hoping that something can be done by NHTSA and/or Lexus to resolve this issue that I am certain is still plaguing thousands of Lexus owners on the road, and putting our and those around us' safety at risk. Surely, a part that obviously and very consistently degrades over the course of 5+ years so often, needs to be addressed and recalled for the sake of safety and integrity.

I have purchased a new Lexus Rx 350 2024 from south county Lexus in mission viejo in March 2024. Upon completion of the purchase, I was informed that I get only one key for the car as there is a shortage of the keys. I was told that it will take a few months to get a 2nd key. Now it is June 6, 2024. I called the Lexus dealership as well as corporate office. I was informed that I probably will get the key in August 2024. I find it absolutely unacceptable. It creates a safety hazard when a 2nd key is not available.

First, we are a victim of fraud and scam and are distressed since day one and loss of thousands of dollars. After searching and reviews, we bought a 2015 Lexus Rx350 for family use from a seller who had owned this vehicle for over five years but the seller never disclosed and represented in the sale of this vehicle that it was rebuilt and had engine front cover timing gasket leak! they said it was clean title and didn’t have any issues. Plus the blind spot sensors had issues. The same day these problems were recovered after we bought it and from the same first day we tried to return the vehicle and used all other option legally from day one till now to resolve it with the seller, but they didn’t want to resolve neither return it or fix the problems with vehicle but they kept denying. Vehicle been sitting in parking lot since the first day of bought and never able to register and it’s been over 8 months. Also found out, these year models like mine 2015 Rx350 timing cover leak were common problem back then. I’m desperately asking to issue a fix remedy by Lexus or Toyota therefore, please help with this. . Thanks in advance!.

While driving car came to an abrupt stop and stalled. (abs) had to engage brake to restart car. Noticed abnormal shifting while driving in nc mountains.

The transmission to oil cooler hose erupted!! oil was sprayed everywhere along highways. Destroying environment this is an environmental safety issue. As well as a vehicle killer. It is a well documented problem with Toyota and Lexus vehicles. Just google it. Many have been recalled. This is a serious design flaw. The government needs to address this. Every mechanic is stunned at how ridiculous it was to use rubber instead of metal. Toyota/ Lexus needs to recall all vehicles snd repair this. And reimburse those who already fixed them or lost their vehicles. One mechanic said this could result in vehicle fires I realize my vehicle is old. But this is an ongoing issue with multiple years involved. Thank you.

Safety concern: engine timing cover oil leak. Blind spot warning malfunction.

My car has 171,000 miles on it and I have a blown head gasket. This vehicle has only been driven by myself and was purchased brand new.

I am writing to you regarding the vehicle safety which I became aware of  recently but there was no solution provided. If this happened to me, it can happen to anyone driving the same model and needs to be addressed as soon as possible before the fatality occurs as this is danger to the public. I was driving a vehicle on [xxx] after just picking it up from service (serviced at ray catena Lexus on [xxx] for 15,000 miles service and oil change) at the rate of speed approximately 65 mph. All of sudden the vehicle started making noises, transmission shifted from auto to lower manual gear and I was barely able to keep control of the vehicle. Luckily, I was able to pull over safely, turned it off, gave it some break and turned back on. Vehicle seemed to be operational and since I was close to the amtrak train in washington DC, I have decided to take the train as intended to florida along with a vehicle. Upon arrival in florida, I was able to take the vehicle to the dealership jm Lexus on [xxx]. I explained the problem and they checked the vehicle and released it to me shortly saying that there was nothing wrong. This dealership charged me $141. 92. As I just left the dealership and got on the highway, the vehicle started to act up again. I was only able to take it back to the same dealership on [xxx], the mechanics did another check on the vehicle and discovered that the spiral cable had an oily residue on it and that was the reason for the electronic issue I was having, but that cable was not covered by the warranty and I was quoted $1,800. 00 to get it fixed. Which is odd considering that not only did I buy out of this vehicle a few weeks prior but the vehicle was just serviced on [xxx] (with odometer reading at 12,728 miles)  never giving any issues prior. After having a back and forth conversation, they dropped the price to nearly $1,000. 00 but being concerned for my and my spouses safety, I had no choice but to pay.   information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

During a routine maintenance at the Lexus dealer where vehicle was purchased, we were told that there was a potential oil leak from ("potentially") the engine where the block, cylinder head, and timing cover components meet. The quote we got for the repair is $18,781. 52 as a good portion of the car needs to be disassembled to access the motor. This issue was only brought up after the warranty expired. The Toyota 2gr-fks 3. 5l v-6 engine in this vehicle is known to leak in this area due to the gasket mating surfaces in the area mentioned above not sealing completely requiring silicone rtv caulk to be installed during engine assembly. If this is not done correctly leaks occur. Lexus refuses to make good on this saying the car is out of warranty. Ironically, after receiving the quote from the dealer for the repair, we received an offer to extend the warranty - available only after this $18k repair was completed.

While vehicle was being driven into the garage the vehicle suddenly accelerated on it own without driver pushing on gas pedal. Vehicles automatic emergency braking did not engage. Vehicle then struck steel shelving and wooden cupboards causing considerable damage to vehicle. The body shop where the vehicle was taken for repair experienced the same surging phenomena when they moved the vehicle. There were no system warning lamps visible prior to the episode. The vehicle has not been inspected by Lexus.

October 20, '23 our recent dead stop! whistle blower! did you know that when the alternator goes out on a Lexus, that the car draws down energy from the battery to keep the car going? that's only for about a mile or so, then the car shuts down! you can't steer and the engine stops running and you have no power as you come to a dead stop, whether on the freeway, or one lane mountain pass road, where we would have been later. What would we have done? scary! luckily, our Lexus stalled on a city street nearing our on-ramp to the freeway. (needing to be towed. ) Lexus has a serious engineering-defective-design-flaw that probably is responsible for accidents. Thanks, doug. Pass it on pleas!.

Dear manager: I have this 2006 Lexus Rx400h which has check vsc system and check hybrid system problems. When I was driving on the highway, the cruise control button is unable to turn on, when at speed of 65 mph it will suddenly stall in the middle of the road and the ready light will be off and the vehicle has to be stopped by the emergency lane which is really dangerous. I have searched online and found out there were many complains about this issue and Lexus issued a recall for this type of car and the dealer can change the inverter and icm free of charge. This recall link is as follows: https://static. Nhtsa. Gov/odi/rcl/2011/rconl-11v342-6633. Pdf so tonight I am sending this message to see if you can help me to solve this problem.
