There are 8 owner-reported fuel system complaints for the 2015 Mercedes-Benz CLA-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
They had recall of this part which is valve in all other models except for this one. My vehicle failed VEIP test due to faulty valve and required assistance from the dealer but they refused to provide solutions and asked to pay $2700 and $230 diagnosis fee when we already had code which showed which part and which is recalled in all other Mercedes vehicles with 150000 milage warranty. We cannot just replace valve they are forcing to replace whole assembly causing problems for many owners like me. My vehicle has only 36k milage. If same valve is faulty which creates environmental hazard that should be recalled in all models from same manufacturer Instead of forcing ripping customers with high cost and environmental risk.
Car smell like fuel possibly fuel injectors or fuel line… recall on 2016-2021 models but 2015 having same issue Blind spot assist says inoperative Mercedes changed sensors multiple times still says inoperative

Same part had been recalled from all other models but not my model. It's the same part being used across Mercedes and they won't sale the valve and force customers like me there are thousands other to spent $2700 plus to replace whole system. Should have been recalled since it's same valve that may be using across all vehicles. Failed the emission test which is a big problem they should have addressed.
On September 7th, 2023 while I was on the fastest lane driving to work in the morning on I 10 fwy, the car shut down without any prior warning. Couldn't even put it in neutral. Called 911 and a cop called the towing service to take the car out of the fwy. Mercedes Benz Ontario dealer diagnostics says it's due to a fuel pump failure. I see a same issue recall, but not for my model. Mercedes should check if my model sold also has a similar fuel pump failure issue. It's very dangerous to stop without any warning.
The factory fuel rubber inlet hose going to the high pressure fuel pump leaks in cold weather conditions. Multiple dealerships and online forums are aware of this fuel leak but a recall has not been issued to have the hose and clamp replaced.
