2010 Lexus RX450H HYBRID - Ratings, Complaints and Recalls

"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."

"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 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."

"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."

"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"

"oil cooller line exploded,engine lost half of oil,repair cost over $400."

"i was driving on 275 highway in tampa, fl, and i got these messages on eco, "motor oil and pressure low" and check engine the mechanic advised to check with the dealer. please advice. thanks"

"tl* the contact owns a 2010 lexus rx 350. the contact stated that while driving at 65 mph, the oil pressure warning light illuminated. the contact pulled off to the side of the road and checked the oil. there was no oil in the vehicle. the contact took the vehicle to an independent mechanic where it was discovered that the oil coolant line fractured. the vehicle was repaired and returned to the contact. after picking up the vehicle, while driving 45 mph, there was an abnormal sound coming from the vehicle. the contact stated that the vehicle started to drive roughly. the vehicle was towed back to the independent mechanic to be diagnosed. the vehicle was diagnosed with engine failure. the vehicle was not repaired. the dealer nor the manufacturer had been notified of the failure. the failure mileage was approximately 160,000."

"while driving under 30 mph. lights came on from the dashlights came on prompting low fuel pressure. shortly after, weird noise coming from engine pulled over to check under the hood. seen a lot of oil lost. had the car towed to lexus dealership and identified that it was hte engine oil cooler pipe. this was a known problem with toyota/lexus. was told that there was a campaign to address the issue but is expired by 10 weeks. :("

"the vvt-i oil line on my lexus rx350 burst while driving on a highway. it was a very large leak which covered the ground, engine, and undercarriage. the low engine oil message and engine oil pressure warnings came on when it happened. complete loss of oil and no visible oil on the dip stick. after looking online and talking with the mechanic this is a known defect with the part though i don't see any recall for it."
