problem #5

Jun 132016

RX 350

  • 136,000 miles


After my previous complaint of experiencing transmission shudders, the car became progressively worse. I had it taken to the local dealer, where they informed me that the transmission had failed. This car has only 136,000 miles, which is not many for the quality usually associated with the Lexus brand. They claim to have no reason for the failure, but are charging me almost $5,700 to replace it. I asked Lexus corporate to assist me with this repair, due to the known transmission issues on many Rx models, but they declined. The vehicle almost died on me in the middle of the highway on several occasions while experiencing these transmission shudders, which could have led to a bad accident. I think this is ridiculous and shows poor quality in their manufacturing.

After having to replace brake calipers, a broken key, and the engine oil cooling pipe (warranty) in the last year, my rx 350 is having transmission shudders with 136K miles. This is ridiculous for a car with the Lexus name and price. The car is hesitating during shifting causing issues while driving. I have not had to replace the transmission yet, but with the reviews for some older models, I fear this is coming soon. I am very disappointed to pay this much money for a quality car that is supposed to last 250K+ miles, and having so many problems with just 136K miles on it. It does not live up to the Lexus quality reputation!

The transmission completely failed while I was driving on the freeway. This was very dangerous and caused a safety hazard. The transmission had to be replaced. The power steering rack had to also be replaced. It's ridiculous that these failures occurred before 120,000 miles.

We have complained about a noise upon starting the car for the past year when having the vehicle serviced. This was the first service visit where dealer was able to pinpoint the code and they came back with the cam shaft variable valve timing (vvt) gear issue. The repair estimate was $6830. I found your recall dated September 4, 2013 # 13V395000 for vvt on Lexus GS350, IS350 and is350C models for the same model year and find it suspicious as the same engine is used. I am wondering if other rx 350S have the same issue and the recall should actually be expanded to include the RX350 model. At this point, the dealer says they need to tear the vehicle down to accurately assess if it is the bolts or another issue but the expense is very high. I also was wondering what the range of miles were on the recalled vehicles? thank you for looking into this.

RX 350

  • 65,000 miles
At 65,000 miles vehicle had a major breakdown. Serpentine belt ruptured causing fire and smoke inside the engine compartment and both inside the cabin and outside. Gas pedal became inoperative and vehicle had to be towed to a repair facility. As further determined the cause of the belt rupture is the A/C compressor freezing stuck. Repair is extremely costly. Parts alone are close to $1500. Lexus is not willing to help in any way and all of the maintenance per the maintenance booklet is performed and on time. Additionally the maintenance booklet does not require any work other than filters, oil changes until 100,000 at which time only spark plugs are mostly due to be replaced. A/C compressor should not have gone out at 65,000 miles on a 2008 Lexus.
