2015 Kia Pro Ceed Engine Issues: Symptoms Point to Possible Lambda Sensor Failure

Hey there! Totally understand where you're coming from. Had a similar issue with my 2018 Kia Rio a while back. Black smoke, decreased acceleration, you name it. Took it to my mechanic who suspected it was a dirty lambda sensor, just like you. In my case it turned out to be the ceramic inside the lambda, it was clogged up bad. Because of this, the sensor couldn't get an accurate read on the car's air/fuel ratio, which meant my engine was running rich (hence the smoke and heavy fuel use). Getting it fixed wasn't really an astronomically huge task, but the mechanic had to remove the sensor from the exhaust system to clean it which took some time. It was more of a time consuming task than a complicated one. And yeah, I'd say it was quite serious, mainly because an impaired lambda sensor could lead to other problems like damaging the catalytic convertor and it also wrecks havoc on the car's fuel efficiency. So, I'd recommend getting your car checked out as soon as you can. That lambda sensor is more vital than most people realize! Best of luck!

Hey there! Many thanks for sharing your experience - sounds pretty similar to what my Pro Ceed’s going through. It’s a relief to hear the fix wasn’t overly complex. Do you remember roughly what they charged you for that job? And has your ride been running smooth ever since, or has anything else popped up along the way? Fingers crossed it's been clear skies for you! Cheers!

Howdy! Happy to help! After my mechanic worked some magic to clear out that mucky ceramic inside the Lambda sensor, I had to part with around 375€. It might sound a bit steep, but as I said, it was more about the time taken to get the job done than the complexity of it. And yes, I've got to say it's been smooth sailing ever since. My trusty Kia Rio's back to its old self, and hasn't shown any of those worrisome signs since the sensor's been fixed. Just go ahead and get the check-up done asap. Fingers crossed it's the same issue and not something more serious. Well, good luck! Take care!

Heyya! This is really helpful. A bit pricey, but it sounds like it's worth it to get the ol' Pro Ceed back on track. I'll definitely take your advice and get the check-up done on priority. Warning signs like these can't be ignored for long, can they? Fingers crossed my car’s issue turns out as 'simple' as yours! Thanks again for taking the time to share, it’s much appreciated. Good to know your Rio is giving you a smooth ride since the fix. Hoping for the same outcome! Take it easy!
