2017 Peugeot 3008 2017 automatic 3008 allure - every so often, the car begins to shudder and slow down.

If fault not there when testing , hard to fix ,You really need to get it scanned for any stored fault codes with Peugeot diagnostics and take it from there , dependent on findings . Other option is to contact Peugeot dealership and check if it's a known fault and any software updates available to rectify this fault .

Thank you - I'll try and get in touch with a dealership.

Hi did you get to the bottom of your issue? I have the same problem at the moment and have the same issue with it coming and going

Hi, my local garage plugged it into their machine and it showed as a mass air sensor might need replacing. This was done however, the original problem prevailed so it wasn't that and that was quite expensive. I recently took it to a dealership and a number of other jobs arose including an 'alternator belt kit'. This too didn't quote as cheap but I've told them I'll have it done. We are just waiting for the part to come in and book it in. Ask me in a couple of weeks, I may have a better answer for you. In the mean time, I have found that when the car starts to struggle, using the minus paddle to drop a gear seems to help. Now, when it happens, I change to the Manual setting and use the paddles for the rest of my journey and usually, when it comes to the next journey, the issue has gone. Hope this helps

Hi, I will check in in a couple of weeks with you if that's ok as what you describe is exactly the same as mine -
if I drop to a lower gear and have more revs on, it runs better, also if I park up and let the engine go cold - come out the next day or so it is usually fine again.
For information - I took mine to a adblue specialist as I had a adblue fault appear around the time I started to get the issue, I had the adblue system programmed out so the car doesn't use it or recognise it is fitted anymore but this didn't cure the problem either

Hi, yes, please do check in again; I'll gladly share any info as it's quite frustrating and I was feeling as though nobody would understand and that I'd been ripped off. As it happens, the dealership hasn't yet called to say the part is in and ready to be fixed. It's been a while now so I'm going to call them tomorrow and check they haven't forgot about me.

Speak soon

Did you get sorted Darren?

Hi, not as yet. The Liverpool Peugeot (Stelantis) could only fit me in on the 20th September :( I'll know more after then so please get in touch. The other week, I drove to Stanstead airport and back without an issue; smooth as anything. Last week, on a local trip, it started to have the shakes but when it does, I just change over to Manual mode and use the padels. That seems to do the job and then I find that the next time I start the car up for another journey, the problem has gone so continue with automatic. It's like the gear it's in when it starts to shake is too high for the speed.
Keep in touch.

Are you fixed now Darren?

No update so far

Hi, sorry Mark. Stellantis fixed what they described as an Alternator Kit which included a new belt etc; all close on £700.. Unfortunately, on the second day whilst going down the motorway 65-70, the car presented with the usual problem, i.e. started to struggle and start shuddering. Usin the remedy above, I used the paddle to drop a gear and this did the trick up to it automatically changing to 6 again and the shuddering began once more. I kept dropping down and it eventually stopped. I felt so disappointed but then I've had over a week of fair mileage without any issue whatsoever until yesterday when it did it again. Again, dropping down a pedal seemed to solve it and then the next time I used the car, it was back to normal and has remained so thus far.
It remains a mystery to me. The car has now had a timing bely long before it's due. I informed Stellantis there was still a problem when they gave me a courtesy call and despite being promised that the service manager would be in touch, they haven't as yet.
Sorry not to have been able to suggest a cause and solution - I'll have to save up for their next advice! Will let you know.

Hi there, I have the same issue. Just wondering if you got it fixed and if so, what was the problem? Many thanks

Been no update since last post (3 months ago)

Hi, no the problem still persists. I still knock down a gear with the pedals as a quick fix. I'm booked into the delership next week but, I know what's going to happen; they'll plug it into their system and the issue won't appear. They'll take it for a drive and the issue won't happen. Should they surprise me and find the issue though, I'll post the outcome.

Thank you Darren

I have the same fault on my 2017. Loses power and shudders and have to drop a gear and rev more clears after a while. But can go few hundred miles no issue. About to contact about a repair myself. Please let us know how you get on! :)

Hi again. Update on the car.
I went to the dealership again who introduced me to their 'master technician'. We went for a drive down the motorway but, as predicted, the issue didn't arise unlike the day before. He told me not to worry about that as going off the descriptions I'd given, he had an idea of what he was going to investigate.
On return for collection, I was given the bad news that the mechanic believed the problem was 'exhaust valves' on the engine. The good news was that they could be replaced, the bad news being they are expensive and that the estimated labour was 15 hours at £150 per hour plus vat.
Had a chat with my everyday mechanic who confirmed it was a big job and too big for him. Also, should I have it all done, there was still no solid guarantee that was the issue.
It's due a service which, I'm going to let my local mechanic do. He's going to apply some special stuff that's good for sorting sticky valves. Fingers crossed for that but should it 'judder' again after, I'm going to have to change car.
Hope this helps others with their experiences. I'm happy to keep the link open and let people know if this anti-sticking valve potion does the job and I'll also get the name of it.
Regards

Darren

It Happened to mine Peugeot 3008 2011 reg nearly 1 and half month ago. i was stopped at motorway as car was losing power and i was unable to accelerate, however engine was still running. I started driving slowly and tried to not accelerate too much and try to change gears so wont have to accelerate and then keep driving at 50 speed. whenever that happened then engine light and traction control showed up together. my car was shacking as well during the start and when running as well but not too much. went to machnice next morning and ironically he said he this is engine misfiring and mightbneed to replace coil or injector. each injector will cost £250. i dropped the car for him and after a day he called me and informed me doesnt look like coil or anjector as they have detached and tested and issue is with fly wheel. i asked if thats regarding to shaking then how come car was losing power during accelaration in motorway. he said he is not getting any reading for that now. he asked me for an amountv of 500 pounds for the flywheel part only and 250 labour if i wanna proceed otherwise 60 pounds for diaganosuitics. i didnt feel statisfied and got impression car will require more money and not reliable. long story short. Fo few days car was losing power during accelateion and if i would driving while changing gear then it was driving without losing power. there are no lights showing and car hasnt lost power after few days of happening this. sorry for long story as i felt needed to highly these issues which might be related with each other incase. booked appointment for another mechanice. car is not losing power but i can reach 70 but looks fragile and unpredictable

Thanks, Azhar
I'm still tolerating mine. Just done the usual today after going a month without issue (longest period ever). A friend of a friend told me to try putting it into manual and at 3rd gear, run it at 50mph on a long stretch of road for about 10 mins. I was beginning to believe this might have cured it! When it happened today though, I found a stretch and did 50 on a manual 3rd gear. I was back to running normal after a few mile. The saga continues!

Not worth spending that money on car of that year . Especially when the mechanic is saying one thing is causing it and changing the story for another guess that in all probability may not even fix the fault .
