A few months after I realised that there is a squeaky noise from the right rear when I go over bumps

I have had a similar issue with my 2017 RX450h F-sport. It passed a recent MOT but the creaking noise was still there on the rear right hand side when I went over raised traffic control ramps. My local Lexus garage checked it out and replaced (yesterday) both L and R training arms, bolts and bushes as both were reportedly showing signs of wear. It has cured the problem. 

The main issue however is that the bushes are not covered under the Lexus relax warranty and Lexus do not supply the bushes only so you have to buy the whole inclusive arm. I complained bitterly but the best my local garage could do was to reduce the labour costs as much as possible. I still had a bill for £1,100. Lexus turned down a warranty claim despite requests to reconsider from the garage service manager. The car has 54,000 miles, I have had 4 Lexus SUVs over the past 15 years and have never encountered this before.

Apologies for typo error

The service report should have read

 “Requires both rear trailing arms with all securing bolts bushes worn and creaking”.

Apparently, just for info, in case your knowledge is as limited as mine, they are the pieces of the suspension system that connects the vehicle's axle to its chassis. The bushes are rubber or polyurethane components that act as cushions and reduce friction between the suspension parts.

Parts cost £697.01

The service report stated “Requires both rear trading arms with all securing bolts bushes worn and creaking”. I had reported the rear right side making a creaking noise when going over a traffic ramp. 

Under the Lexus Relax Suspension section it lists “Front and Rear Springs; Torsion Bars; Track Rods; Stub Axle; Cross Members; Sub frames; Wheel Bearings (limited up to 160,000km); Hubs; Shims; Lock Nuts;”

Sunroof update. Just heard from Lexus Belfast that the total cost of the pan sunroof will be covered by Lexus (5k+). Thank you Paul. Unfortunately the suspension will not as they deem it to be wear and tear despite the recent MOT success. 

No update from the dealer as yet, they have put in a request to Lexus to cover the defects 

Ref the suspension issue, my car 2017 RX450 F-Sport with 50,000+ miles passed the Government run MOT test 2 weeks ago so I was surprised to hear that both rear suspension arms required replacing.

Thanks Colin and Nigel I am waiting on my local dealership to query this repair/replacement with Lexus as I do get the car serviced regularly with Lexus. Fingers crossed.

Speaking of warranty would the replacement of both suspension rear trailing arms with all securing bolts be covered as they were worn and creaking

I have been informed that the whole pan roof has to be replaced at a parts cost of nearly 5K and then labour costs on top. Does anyone know if a seal can be bought separately?

Can you replace the rubber seals around a panoramic sunroof on a 2017 RX450 F-Sport?
