ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
I bought my vehicle into Mercedes Benz for a recall related to water collection in spare tire well which can cause a fuel pump control malfunction, NHTSA recall # 22V955. A few days ago, my vehicle could not start and I found water in my spare tire well. My OBD scanner tells me it is related to the fuel pump. I informed Mercedes Benz and they would not fix it. Obviously the work performed did not correct the recall. I'm writing here hoping I can get connected to the right channel to get this resolved as my vehicle is currently unusable. Thanks.

LANE DEPARTURE: BLIND SPOT DETECTION, EXTERIOR LIGHTING, ELECTRICAL SYSTEM
I was driving from Florida to my home in Washington, DC on September 4th, 2023 on I-95. Somewhere in South Carolina, a message appeared on my display that said the blind spot assistant was disabled. Soon thereafter, my turn signals quit functioning. At first chance, I pulled over and turned the car off hoping it was some kind of computer reset. That worked but only for an hour or so. I made it home ok but not having turn signals was very dangerous and very concerning. I took the car to a local DC Mercedes mechanic who ran a diagnostic but nothing came up because the systems were functioning at the time. He took the car for a drive and they stopped working for him. He said take it to a dealer. I have an appointment for next week. I also have searched for this problem on social and it is definitely a problem with other owners. The part is nearly $700 and it is a big job to pull the steering wheel and replace this. I think this is a serious flaw and consumers should not be burdened with non-working turn signals. I think it might be a design flaw in their switch. Please look into this if you think as I do. Thank you.

ENGINE
CUANDO ENCIENDO MI GUAGUA HACE UN RUIDO MUY FUERTE Y SE SIENTE COMO SI SE VA A APAGAR. EL MOTOR SE PUEDE ROMPER EN CUALQUIER MOMENTO. SI SE HA LLEVADO A DIFERENTES TALLERES PARA CONFIRMAR EL RUIDO Y ME REFIEREN QUE SON MAS DE 80 GUAGUAS QUE HAN VISITADO SU TALLER CON EL MISMO PROBLEMA. NO PRESENTA NINGUNA ADVERTENCIA CUANDO APARECIO POR PRIMERA VEZ. EN EL TALLER ME DICEN QUE SE DEBE CAMBIAR EL MOTOR POR QUE SON LOS MOTOR STROKER Y ESO PUEDE CAUSAR UN FEO ACCIDENTE. WHEN I TURN ON MY BUS IT MAKES A VERY LOUD NOISE AND IT FEELS LIKE IT'S GOING TO TURN OFF. THE ENGINE CAN BREAK AT ANY TIME. IF IT HAS BEEN TAKEN TO DIFFERENT WORKSHOPS TO CONFIRM THE NOISE AND THEY TELL ME THAT THERE ARE MORE THAN 80 BUSES THAT HAVE VISITED THEIR WORKSHOP WITH THE SAME PROBLEM. IT DOES NOT PRESENT ANY WARNING WHEN IT FIRST APPEARED. IN THE WORKSHOP THEY TELL ME THAT THE ENGINE MUST BE CHANGED BECAUSE THEY ARE THE STROKER ENGINES AND THAT CAN CAUSE AN UGLY ACCIDENT.

ELECTRICAL SYSTEM
Turn signals stop working after driving a mile or so. If possible, I turn the car off and on. Turn signals work but fail again within a few miles. Hazard light work even when the turn signals fail. I’ve read this is a common issue searching the internet. Definitely a safety concern

SERVICE BRAKES
Previously submitted to webmaster and recorded under Request # [XXX] I experienced catastrophic brake failure while driving the vehicle. As you see above all recalls have been completed and the vehicle has never been in an accident to my knowledge. I stopped the vehicle without incident or damage and had it towed to a repair shop. They determined that both rear brake lines were corroded and replaced them. I didn't think a catastrophic failure was possible in a vehicle with a dual brake system, but apparently that is not the case in this vehicle. How many similar cases have been reported? Do I have recourse to the manufacturer as it surely seems like a failure of the OEM part The vehicle has 101,000 miles on it and is in excellent condition. I am concerned that this type of catastrophic brake failure will be fatal to someone in the near future. I was lucky and was only traveling at about 5mph and was able to stop the vehicle on the curb.

SUSPENSION
In April 2023, while performing a rear brake service both right and left suspension springs were found with deteriorated suspension spring coating, corrosion and breakage of the coil springs. Suspension spring failure poses a safety hazard and risk of damage to other suspension components. It is unclear when exactly the springs broke but when the vehicle was inspected in Feb of 2022 there was no mention of spring breakage. The date of incident is the date I discovered the spring breaks. I only took a pic of the one spring but both were confirmed broken. MB dealership confirmed breakage. Communication with Mercedes Benz was not successful.

FUEL/PROPULSION SYSTEM, EXTERIOR LIGHTING
Due to water in the spare wheel well, (Recall ID:22V955) our fuel module and fuel pump went out. While driving in traffic on I-5 our car stalled then stopped which put us at risk of a crash.The first time (July 2022) It was repaired by Cooper's Auto Repair), After the 2nd time it failed again in Aug 2022, once again as we were driving, our mechanic at (Boyle's Foreign Car Repair) Aug 2022 & Dec 2022 (replace) decided to do an inspection of the whole car to see why this was happening, upon inspection he found water in the spare wheel well, He pulled out the plug to stop accumulation. 2 months later (Feb 2023 )we received the recall letter. In the letter it states that MBUSA would reimburse repairs performed prior to the recall. MBUSA is now refusing to reimburse for replacement but also refusing to find and fix where the water in entering. We reside in a very wet part of the country and see this as a continuing issue. There also is condensation in the back tail lights, which was not there until this issue started occurring. The car was previously in S Cal so there was no issue with water accumulation until it was moved to the rainy Pacific NW. We are fearful of using this car during very wet times as we do not know if this (failure of pump/module) will occur as well as condensation and water being in the back tail lights possibly resulting in the car stopping during it being driven. Therefore putting our lives in potential danger of an accident.
