2010 LEXUS RX Complaints

The Power steering had started to feel hard and squeaking some time ago. I was driving day before yesterday and I noticed a few times that the steering was very difficult to turn which could have been dangerous. While doing some research I found that this has happened to some RX models. I went to the dealer and they told me that there is no recall for this issue and any fix would be out of pocket.

Water leakage problem in the trunk area causing water buildup on and around the spare tire. A rust issue and potential electric short circuit issue.

We were 2 hours into a 9 hour drive when I noticed smoke in the rear view mirror. I continued to drive as I thought it may have been coming from another vehicle. I drove to the nearest gas station (about 3 mi) and pulled in. Upon exiting the vehicle, we found the back window and the entire back of the SUV covered in oil. There were no warning lights and no engine noises. We checked the oil and it was so low that it did not register on the dip stick. We added 2 quarts of oil which then registered on the tip of the dip stick. We then added another quart of oil and drove to a nearby service station (1/2 mi). The mechanic could not diagnose the problem since he couldn't put it on his lift (it was occupied by another vehicle). He contacted two other service stations in the area and found one less than a mile away that had a lift open. We added 2 more quarts of oil and drove to the next service station. The mechanic put the vehicle on the lift and quickly found the problem - a pin hole in the oil line. He was able to find a replacement part (not the original part as it had been discontinued) and get us up and running the same day. We were very fortunate that I noticed the smoke - if I had not noticed it and continued to drive (we were 10 minutes from driving over a bridge tunnel) it could have been catastrophic. We finished the 7 additional hours of driving that day and after being gone for a week, have now returned home (another 9 hours). The mechanic told me the part had been recalled, but when I searched this sight, I found lots of similar reports - but no recall. Coincidentally, I had had the oil changed 4 days before beginning this trip. It is surprising that there are so many reports of this incident, but no recall by Lexus.

Driving along normally, started seeing a flashing "low oil pressure warning". Within seconds, engine started revving uncontrollably and would not make power. Was able to coast into a parking lot. On dipstick inspection, engine had lost ALL engine oil and entire car was covered in oil. Suspect that oil spilled out at some point on the road- danger to other cars. Vehicle was towed to local dealer, diagnosed as a blown oil cooler pipe, causes all engine oil to spray out in seconds. This is a known problem, addressed in Lexus Technical Service Bulletin L-SB-0154-11 and a recalled part in Canada, but not in the US. Factory part is a rubber oil line that deteriorates and bursts, Lexus has an upgraded medal line available. Service invoice can be updated once service completed if needed.

the rubber oil cooler hose busted/exploded on 6/03/2021 on the way home from vacation 2 hours away from home late at night with my 2 children. there were no warning lights etc. all of a sudden it started making this horrible sound, i stopped on side of rode to everything covered in oil. had to get the vehicle towed to home. the engine and all under hood was covered in oil. i see tons and tons of complaints on this issue but no recalls. i would think this is very dangerous. shouldn’t this be replaced for free and /or reimbursement. spoke with ballet lexus roswell. they were familiar with this problem but no reimbursement offered therefore vehicle is still sitting in garage undeliverable.

Oil cooler line, rubber elbow potential failure. No notice letter from Lexus received warning of their TSB: POL.14.02 (NHTSA#: 10056509). Voluntary extended warranty coverage is expired now and no support from Lexus offered. Rubber elbow cannot be simply replaced as the newly desigend replacement is a metal elbow. Entire assembly must be replaced. Extremely expensive. Unacceptable for a flaw to endanger the engine, and possibly to cause a fire with oil spray onto a hot engine/exhaust.

Oil cooler high pressure line, rubber elbow, pin hole oil leak/spray. TSB: POL.14.02 (NHTSA: 10056509). Leaked oil out with check engine light/low oil pressure warning just as I arrived home. Line of oil in driveway. Diagnosed leak from this rubber elbow. One quart of oil left in oil pan. After review of NHTSA website (and many, many Google hits) found this to be a well known problen by Lexus. No recall ever issued. I never received written notice from Lexus, and dealership that vehicle has been to many times never mentioned anything. Lexus denies any extended warranty at this time. Absolutely unacceptable.

The contact owns a 2010 LEXUS RX350. The contact stated while driving 65 mph, she saw light white smoke floating through the air which she initially assumed came from the vehicle ahead of her. As she exited the highway and came to a stop, the low oil pressure warning light illuminated with an abnormal knocking sound coming from the engine. The contact pulled over and called her brother for assistance. Upon inspection, the contact's brother discovered that there was no oil in the vehicle, even though the vehicle had received an oil change five days prior. The contact called the local dealer who offered to tow the vehicle to the dealer to be inspected. The contact declined the tow, and instead had the vehicle towed to Lexus of Pleasanton (4345 Rosewood Dr, Pleasanton, CA 94588) where the mechanic discovered that the engine oil cooler pipe was fractured. The contact discovered an unknown recall on the vehicle. The manufacturer was notified of the failure. The contact was informed that the Vin was not under recall or warranty. The vehicle was not repaired. The failure mileage was approximately 199,000.

The hybrid transmission failed at 146k and the light went on. When we took it to the dealership, they said that there was metal bits. The owner of the vehicle when into the dealership asking the dealership to set tire pressures and inspect floor mats for proper installation, they performed an inspection and inflated the tires. The owner went in and stated that the check hybrid system warning light is on. Oil pump range/performance. NOTE: no road test performed. Possible additional work needed. Transmission oil pump inoperable due to metal in fluid shorting the pump. The dealership took a fluid sample. They had found lots of metal particles present in the fluid. They recommend replacing the transmission, oil pump, cooler, cooler hoses, and clamps, flush the metal lines.

MY OIL COOLER LINE BUSTED AND DID NOT KNOW TILL I GOT HOME THANK GOD THE ENGINE DID NOT SEIZE. COME TO FIND OUT THE LINE IS MADE OF RUBBER AND NOT METAL. I UNDERSTAND LEXUS IS AWARE BUT THEY ARE NOT CALLING FOR A RECALL. I TH8NK THEY SHOULD PAY FOR WORK PERFORMED
