Mine was fixed last July when they adjusted the strut and locating block. Unfortunatley its come back again. I have shoved the yellow duster back in position and it's going back in to be looked at on Thursday along with another annoying rattle from the region of the passenger side A-pillar.

I bet the that the majority of C-HR suffer from these rattles. The problem being that many owners in their pensioner years cant hear them. My parents 75 and 79 can't hear any of the rattles I can and I'm 48. I seriously would get rid of a car with a rattle / unknown noise it drives me to distraction. I know I should just turn the radio up but I just can't. Never mind in another 20 years when my hearing starts to go I won't need to worry about it in whatever car, probably electric, I am driving then :lol:

At just over 4000 miles, the rattle from the rear has got the the point where it's really annoying.

Not the number plate as that's screwed & taped.

Will mention the rear suspension & hatch strut.

Do you have any news regarding this?

I'm sorry but not had chance to take it in yet. It's the wife's car so trying to work out the timing isn't easy (and she hates going to garages).

The first time did they replace the strut or just adjusted? If just the second i wonder how :?:

 

[DuncanM]

They apparently only adjusted the rubber locating block. They did it again last week and the sound has gone, but I expect it will come back in a few months !

Thank you for the clarification.

 

[toyotachrdude]

Sounds to me that adding mass to the rubber locating block solves the problem. Must be too much movement between the boot door and the block over time the rubber wears down.

A stupid design fault by the sounds of it, and one I'm sure Toyota will (not) fix!

 

[BILL_HYBRID]

I have bought a facelift C-HR,which has this tapping sound from new (3 months old).
I have tried several things with the rubber block, but with no result.
The sound ruins the whole driving experience.
Toyota should find a solution,as it seems that it's not an isolated problem.

 

[Karmalakas]

But there is a solution. Check earlier replies in this topic. Eg. https://www.chrforums.uk/viewtopic.php?p=9599#p9599

 

[BILL_HYBRID]

I have tried every single of the above mentioned solutions.Nothing works.
I think Toyota should offer a revised part,as it's a known problem that the existing rubber blocks cannot handle the moving of the heavy tailgate.

 

[Karmalakas]

What rubber blocks? Did you read about the strut?

Mate,I have read about the strut,but I don't think it can be adjusted.Only the rubber blocks can manage the movement of the tailgate.I believe that's the cause of the tapping sound problem.
To be honest,coming from a BMW,I find the build quality (not the material's quality) and the soundproofing of the C-HR poor. It's a shame because the C-HR Hybrid is the most technologically advanced car in its segment.It seems that we can't have it all...

Correct. I have the 2 liter 2020 model, same problem, very annoying and the rattling is difficult to locate. It's a bad coupling between the tailgate and the rubber blocks, that causes a lateral moving /vibration of the tailgate. I've put a thin rubber layer under the right tailgate rubber block (+ some grease) because the rattling in my case was coming mainly from the right side. Problem solved.
I think the flaw appears after some time, so isn't detected during the factory checks. Generally speaking I've noticed a good quality on the Toyota coupling of parts but yes, this is a bad flaw considering the car's class.

 

[BILL_HYBRID]

I have found the exactly same solution.I have put some layers of thick double sided tape under the right rubber block.The tapping sound is not completely gone,but is has been reduced a lot.

 

[Angusan]

The tapping noise completely disappears when the tailgate is well stopped by the rubber blocks. I'd put some grease on the rubber (vertical side) and if necessary the left block too can be thickened.

I took my CHR to garage after only 100 miles, they found loose wire behind rear door panel, was OK for a few hundred miles then started again. Took everything out of boot including parcel shelf, rear boot cover, polystyrene former that holds jack etc and small access panels from rear door panel but not cured. Even rode in back of boot for several miles to try to locate noise. Short of stripping whole back end out cant think of next option as dealer not happy I brought car back and did not want to spend time on free fault finding session.

I had this knocking issue on my 2001 Avenisis and tried everything to suppress it. Looks like the design is flawed or tailgate set is key to eliminating.
I've noticed my C-HR tailgate is under flush to bumper. This may be due to this issue. I've Re-adjusted striker to gain a flush between lamps and no rattle noticed yet.
Tailgate can have a Manufacturing tolerance of +/- 1.5mm so if at smaller extreme, may end up with no contact to buffers.
Try adjusting striker down a little and see if that eliminates any rattle.

 

[Stephengreen]

Had our new orange edition delivered on 30.6.20. It took me 100 miles to get to the bottom of a constant rattling from the rear of the car. It literally drove me nuts and ruined the driving, and ownership experience of the car. Tried the parcel shelf, gas struts, seat belts, dropped rear seats all to no avail. Turned out to be the fuse cover next to the battery in the boot well. It was very loose even though attached properly and the sound transfering down the metal cage and transmitting and amplifying through the boot well. I lined the inside of the lid with velcro so it was a tight fit and hey presto problem solved.

 

[adn1962]

Problem is, not all cars produced are tested for squeaks and rattles. Prototypes will be, however, parts are subject to variation in manufacture and processing at plant.
Manufacturers ( not all ) only audit sample. Some luxury car manufacturers road test all their cars over improvised road conditions listening for these issues. Toyota will be one of those who only audit due to volumes produced.
Make sure you report this to customer care team so they can feed it back to designers and build plant.

 

[Toooldforthis]

I have had my 2nd C-HR for 3 weeks, 200 miles, and have finally managed to identify the same problem that others are experiencing from the tailgate. Should have searched this forum first. Currently trying different adjustment/padding options to resolve this very annoying issue, which, as daft as it sounds, does detract from the enjoyment of driving this great car.

 

[JayB40]

Just picked up my new 2.0 Excel yesterday and I'm experiencing the same knocking noise coming from the rear, not nice when my old one didn't do the same thing. Guess I will have to check all the usual suspect places and also the fuse cover as above to see if that fixes the issue, if not then a trip to the dealer again. Already having to get them to turn on the Road Sign Assist as it isn't switched on and is greyed out on the Vehicle settings, really annoying when you expect these to be already active.
