Good Afternoon!

I am curious if any of you have experienced vibrations at between 60-65 mph that can be felt in the vehicle and steering wheel? I also get vibrations during faster than normal accelerations from a dead stop or while still moving. I have taken this in to be evaluated. However, their solution was to floor it to 70mph+ on a busy road (35mph Speed Limit zone) and say that they could barely feel anything. They went on the blame some mud in my rim and very begrudgingly agreed to rebalance my tires. It did next to nothing. I went home and checked the tire pressures. They were off still. I resolved that issue, and although the vibrations are not as bad, they still exist. My 2014 Chevy Volt rides smoother at these speeds and acceleration. Thoughts?

Got an XC40 Recharge in January. Immediately started having vibration poster mentioned between 65-75 mph. Thought it was maybe the lane control or something else, but as I did 95% of my driving in a city <45 mph it was more of an occasional nuisance. Finally, took it in to the dealer to check out and they were at first surprised by report but immediately within putting it up on the lift saw that all 4 axles were bent. You can see the technician video here - volvo-bent-axles.mp4

The Volvo tech said HQ is aware of this problem, but so far no fix has been provided yet.

This is starting to sound like recall territory but they need to identify the manufacturing problem and get replacement parts first.

Looks like the Technical Journal article posted eariler in this thread was updated to TJ36424.1.1-2023-04-12 from TJ36424.1.0-2023-01-10. Car is going back in next week for another minor issue and they have told me that they will do a test drive with a "Master Tech" and I to demonstrate the issue.

I wonder how many other's paid for a subscription and learned that other than the update on the name THERE IS NO CHANGE!:

"Please start by following TJ 32161 to first exclude that the vibrations do not emanate from the wheels or
wheel alignment.
If the issue still occurs after the above has been ruled out, do not replace any parts or perform further
diagnosis. Analysis is ongoing to understand this concern.
This TJ will be updated when more information becomes available"

Has anyone written a concise description of the vibration in TJ 36424.1.0? We might be dealing with multiple issues. Below is an update to my previous report on freeway NVH:

My P8 with 1,500km (firmware v2.8, P Zero elect tyres) definitely has a rhythmic pulsing vibration (NVH) starting at about 105km/hr. It's worse on some smooth roads and when the tyres are warm which leads me to believe that a fundamental harmonic of the tyres/suspension is incident with the harmonic from the drive train as you can feel the motors pulsing and surging - I presume this is a coded drivetrain power optimisation? Maybe software updates can fix that, but the tyre NVH probably nothing that can be done other than changing brands.

Does it only happen at 110 kph, or does it just get increasingly louder as you approach 110 kph?

It starts at about 105km/hr and peaks past our legal speed limit.

Greg S said:
I plan to change to a different tyre (probably a Michelin EV tyre with the foam noise suppression ring) when these Pirelli P Zeros wear out.

That sounds like an exceedingly good idea.

I was looking through my Volvo emails for technical report numbers and noticed that my service centre quoted TJ36424 to me on 23rd November which precedes the earlier publication date by a couple of weeks.

The master tech has logged a separate technical report for each of the three XC40s I've taken in, but as of yesterday there's still no response from Volvo on TJ36424.

I'm not expecting anything to come of the complaint Care by Volvo raised for me (I haven't even seen what they've written in it). So, my next step is to find a twin MY 24 demo and take it for a test drive on the motorway.

Please post the results of the MY 24 test drive. I'm certain that the new twin configuration will fix the vibrations.

TJ 36424.1.0 dated 2022-12-13 seems to be current. At least that was the information (or lack thereof) given to me last week by technician when I complained of drivetrain vibration. Volvo’s recommendation is ‘do nothing’. At least it can be cited as a “known problem”.

I've been told the earliest I can test drive a MY 24 is September 😞.

Understandable. We were told test drive mid October, delivery November as of todsy

Not really, I told Volvo I was happy to travel to a dealer that had a MY 24 demonstrator first (they do exist according to the reviews, but not sure if they are just pre-production) but they could only manage to redirect me to my local dealer who isn't getting one until September because they need to clear their MY 23 stock first.

Maybe the RHD build slots aren't scheduled until August, but dealers somewhere must be getting delivery of the units being assembled now.

I'm due to take delivery of a MY 24 plus in October, so doesn't leave much time to cancel if necessary.

my dealer gave me the opportunity to swap to an EX30 from out C40 twin my24 ultimate that's on order.

Luckily we already have a xc40 twin with no noticeable problems

Did they have any pricing info on the EX30 yet?

Was told it will vary between 41k and 55k euros depending on battery size and if it’s rwd or awd. I have a meeting with them this week to see the specs.

Our ultimate xc40/c40 are at 67k for the rwd and 77k euros for awd (for comparison’s sake)

You are lucky. I would love mine without the vibration issue. I just can't get past it.

Hello everyone, I took my car in today to have the vibration checked out (Volvo service were kind enough to slip me in between two scheduled appointments). They ended up changing the right rear tire, after checking the balance and road force, and citing a "large road force variation". More specifically they "noticed the right rear having a large offset as per TJ 36580" (which I assume is specific to Pirelli Scorpion tires). Worth noting: they did not cite TJ 36424.

I took the car out tonight for a test drive, and optimistically, I want to say it's a bit better. There is still some occasional vibrating, but I would say it's not as consistent as before - it happens occasionally on strong acceleration, and also on coasting (always with OPD turned on). So... I'll still need to test it out for a while, but I'd say it's better.

I had no vibrations with stock wheels/tires on C40. I replaced them with aftermarket wheels and tires with regular balancing and noticed a slight vibration between 60-65 mph. It's not enough to bother me, but if it were worse, I'd try road force balancing. That makes me believe the wheels/tires can cause the vibration issue, at least in my case.

Took the car in again to resolve the seat issue (needed a part ordered) got a lot of pushback from the service advisor including "We have never seen that" type of response. Multiple emails CC'ing the Service Manager and the GM of the dealership citing the relevant TJ's and the fact that a simple search show up a significant number of folks worldwide having the issue, I get this from them: "Just got word the other day from my manager and a few other employees that have the all electric cars and did confirm with them there is a bit of vibration whilst driving but seems to be common at this time, He said best we can do is re balance all the wheels and wait for Volvo to come out with a better long term fix. " I am making sure to get all my encounters documented in case I need to pull the trigger on Code § 1793.22(e)(2).) , California Lemon Law. Too bad because I love this car. I will wait a bit to see if they come up with a fix before escalating.

Cheers.

Glad to hear that you are documenting everything. I don't know about California but the general US Lemon Law stated that four (4) trips in for the same issue is the trigger. I'd gladly go that route but the dealer is holding the paperwork for the second trip and states that the ticket is still open, and waiting for Volvo corporate to come up with a fix. It's been more than six months since the initial TJ listing with no fix and five months that I've had the problem. I'm going to take it somewhere other than the Volvo dealer and ask that they just look at the front end. I've seen a video of someone's wobbly axle but who knows how that happened. I know that I haven't hit a pothole or curb with mine.

Because this issue can mask tire, wheel, and various other issues it is a safety problem. The longer it continues without a fix from Volvo the more that I am convinced that they have change the front drive train on MY24, not just to improve mileage but to correct this engineering mistake. The question is what is Volvo willing to do for the many of us who have what "seems to be common at this time"?

I specifically asked them (in writing)to close the inital work order and open a second. IMHO failure to do that would look like they are stalling for a fix or gaming the system. I made 2 trips 3 weeks apart for the same issue. . Not a lawer, but that might look like bad faith on the part of the dealership. Constructively that is 2 attempts. On the safety aspect I feel that the steering wheel vibration closely emulates the lane keeping aid. Thinking I am getting those spurious warnings forces me to turn it off.

That axle video was interesting but that car was up on a rack with the suspension at full extention. The observable runout might just be a function of the axle's angle to the CV joints. Have to take them off and run them between centers to properly measure. Getting an XC40 loaner tommorow, anybody want to bet on it having the same issue?

Cheers.

Picked up the 2023 XC40 Plus loaner this morning. Suprise,suprise it has the same issue. Talking with the SA he mentioned that the Service Managers C40 has the issue also. They are going to force balance the wheels per the TJ but not holding out much hope that is the resolution. I understand they have to follow the steps in the TJ.

Cheers.
