I've had my Diesel 14 Cruze for about 10K miles. It has never come up with any messages about regen. Suddenly the turbo stopped working and a message came on that said reduced power. It's still under the bumper to bumper warranty. I took it into a dealer and they said the particulate filter is clogged and it needed to go into regen. They are telling me they could';t find anything wrong so they are charging me $320 to put it through regen. If there wasn't a problem, why didn't it go through regen? What's the point of a factory warranty?

Anyone else have this issue?

Normally you never see a message about Regen, I assure you it must have done passive Regen to get to 10 k miles. What it sounds like is you got caught in the pre-regen glitch. It has been noted on this forum that if the pre-regen is interrupted you get the full DPF and reduced power at next start up, as you describe. This requires a dealer initiated manual regeneration, but should absolutely be covered under warranty. Some have installed a device called Scan Gauge 2 that has been set up for the Diesel Cruze and it will warn of when the car is approaching Regen or when it's in progress, no installed gauge by GM clearly indicates this, but a drop in MPG is an indicator, also, if you have the engine cooling fan on when you shut off the car, chances are you were in Regen when the car was shut off. Apparently GM and other OEMs think owners are not interested or too incompetent to handle information on Regen, in other markets there is a dash warning light to indicate when it's doing a regen.
I use Ultragage, but it doesn't directly monitor regen, but manifold pressure and exhaust gas temperature gives it away so I can know from that.

Agree with the previous post, get to a different dealer and tell GM customer assistance about your situation. That dealer seems to be setting you up for a rip off.

One other thing, other than Scan Gauge or another monitor, a brief cool down idle before you shut off the car may also prevent re occurrence, I have my wife doing this for her car, she is not interested in monitoring temperatures and pressures, since I do, I've found a 30 to 45 second idle greatly lowers exhaust temp and I think it prevents the pre-regen interruption glitch, though it has not yet happened to me.

Cruze Diesel problems

My 14 Cruze Diesel is in the shop right now. The 'reduced engine power" warning came on. The dealer is telling me the diesel particulate filter is clogged and I have to pay $320 for them to do a manual regen to clean it even though the car is supposed to do it on it's own. I'm still under warranty and have to pay $320 to fix the car????? I called customer service and without even talking to the dealership they were already getting me ready to hear no. They said they will have the dealership call me back. Who approved warranty claims? GM, not the dealer. Now the finger pointing is going to start.

Did the dealer say WHY they are expecting you to pay for a manual regen? I don't think you should have to find another dealer to honor warranty service. That's letting them off the hook.

Send a PM to GM customer care here on this forum. They are wonderful to work with and should help straighten your issue out.

This dealer shouldn't be in business if they are not going to honor a warranty claim without a gun to their head, I would complain and request another dealer and have a positive experience, I would also go out to social media and leaves some unpleasant reviews of your experience, this is utter non sense, you didn't do anything wrong.

I called GM customer service and she was already getting me ready to hear a no. "If the dealer is telling you it's not a warranty item then, we may not be able to help you". Last I checked, the dealership isn't the final word on warranty coverage. Waiting on a response back. I had dropped the car off at a car wash, and the error came on when I started it. It may have started a regen while it was being driven through the wash and was shut off in the middle.

The dealer has me by the balls because I had to authorize the regen so they could diag it. They said it would be covered I they found a problem. No authorization=no diag

The reason you are likely being charged is that they feel it's your fault it's plugged. Owning a diesel is a good thing, but like any newer car there are little issue's that follow. In order for the emissions devices to work correctly on a modern diesel the exhaust gas temp has to be high enough. I see a lot of people on here who post with almost the thought they their car is special and has a calibration where only there car does this. The regen on your car runs by itself on a program without a light coming on the dash. You'll know because your fuel mileage will drop on the highway for a bit or in the city because the fan will be running on kill when you wouldn't normally expect it to. If you don't drive enough to let the car go through it's regen as it's factory set up to be it will plug the DPF. That isn't GM's fault. This same problem for example has been a problem for the Dodge 3.0L V6 diesel. This is one of the reasons modern diesels can be a problem even for the big boy diesels that are used for daily driving and not working hard. If you want to stick with the wonderful diesel in your Cruze you need to work with it which means to at least once a month take it for an extended drive and in fact ring it out a couple times if possible. Running it hard create's more particles, but the heat build up will help it burn off much quicker. Low EGT's also are a killer for the O2 sensor's. My wife's car is often used for short trips around town and I make sure at a minimum it makes it up to proper temp before I kill it as well as let it idle for a minute or so extra if I've ran it hard. Because short trips aren't uncommon for it I take it out at least once a month for a 20 minute or longer drive with a few full boost runs and have never had one O2 sensor code and never one single issue with the DPF. In the future electric DPF's will fix this issue with burn off times of a few minutes. Until then we have to deal with what is there. Removing the DPF btw isn't the solution either. No need to make for a dirty diesel when it's not needed.

If all else fails, put it on a credit card and then immediately challenge the charge as a warranty repair that should have been charged to GM, not you. The bumper to bumper warranty covers ALL items and normal operations except wear items. Regens are part of the normal operations of the car and they are out of the control of the owner.

Also, the call center for GM customer service sucks. Our Chevy Customer Care reps here seem to be much better at getting dealerships to own up to their obligations.

This won't fly in a court. The car is sold to consumers and there is nothing in the owners manual about not doing a lot of short stop & go driving where the engine and exhaust systems don't reach operating temperatures will cause problems. This issue actually needs to be reported to both the EPA and NHTSA as a failure of the emissions system.

crazy talk, they built the car....theres no raisin to not inform the driver that more driving is needed to complete the burn....thats why that msg is programmed...many have said they got no such msg, or got the msg and seconds later limp mode.

thats entirely gms fault.

Hello maypearl,

We're sorry to hear you're having such a tough time with your Cruze. We would be happy to touch base with the involved dealership for clarification and review your situation in greater depth. We're available via private message and would need your VIN, mileage, contact information, and preferred dealer to get started.

Thank you,

Jasmine

You both bring up the key point. Manufactures are going to have to start training customers how these work and how they are going to need to be cared for. GM, Ford, and Dodge are all running into this and VW didn't simply because well... Even on the 2500 and 3500 series trucks the DPF is a big problem if you buy it because you simply wanted the big truck and don't work it enough to burn off the DPF and keep it clean. In court it would fall on the manufacture if a customer wanted to take it that far. The question would come down to if it is the manufacture's job to teach you this or your responsibility to learn it on your own. It should be explained with a paper signed off after the training. Diesels are great for their mileage, but need the equipment to make them run clean enough to make it worth it. Even the EU is learning this and slowly working toward matching our emissions standards. This same problem happened with the hybrid's. They do not get great mileage unless you drive them a specific way. Instead of training they put gauges in them to let you know when you're not doing it right. If they did that with these cars every odd customer would be in there talking about their DPF percentage and burn based on knowledge they've learned online by asking those who also don't actually know but are more than willing to spill on.

There is a video on youtube of a Colorado diesel owner complaining that his truck went into limp mode after he ignored all the warnings for days about needing a regen. He calls the truck a lemon, reality is this is exactly how modern diesel work and dealerships and salesman really need to make sure people are not driving tons of short trips and understand how the emissions systems work before they sell one.

while a good idea go figure work was 10miles from me and i did that for a full year and not one emissions issue .but yes not as simple as gassers fill and drive forget about it.

In my case, I have a 50 mile one way commute to work. Plenty of time for a regen. I've never seen a message about a regen.

the car doesnt know how long youre gonna drive it.

the regen couldve been needed at the 48 mile mark of your drive....2 miles isnt enough time.

but thats not that point.

you werent warned that you needed to keep driving as explained in the owners manual.

youre allowed to drive this car in the city, itll just regen more....sposed to be engineered to deal with that.
