EXTERIOR LIGHTING, STEERING, VISIBILITY/WIPER
2020 Mercedes-Benz Sprinter. When the right turn signal is activated and the steering wheel is turned right, the windshield wipers activate unexpectedly. Diagnostic codes B230015 and B230615 are stored, indicating windshield wiper switch and wipe/wash malfunction. Concern appears related to the steering column multifunction switch/module. This affects driver visibility and steering-column control functions during turning/signaling.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, EQUIPMENT:RECREATIONAL VEHICLE/TRAILER
Following Jayco and Entegra instructions, I delivered my coach to Blue Compass RV. It has now been more than SIX MONTHS out of service. Jayco Pre-Authorization has denied the required battery replacement and referred me to the battery manufacturer, even though Entegra bulletins and recall procedures identify and correct the conditions that caused the damage. Completed Recall and TSB Work Approved by Entegra and Jayco · 22-075 (TSB) A/C Electrical Connection Instructions, September 2022. Replaces WAGO connectors. · 22-076 (TSB) Firefly Terminator G4 Tap Connector, September 2022. Corrects communication errors within the lithium battery network. · 23-101 (TSB) Front Spotlight Electrical Update, April 2023, revised September 2023. Mitigates spotlight over current that can affect Firefly. Adds harness, relay, and software. · 23-120 (TSB) Renogy Inverter Settings, November 2023. Updates parameters; requires Battery Type = LF16 and custom set points. · 23-123 (TSB) Alternator Fuse Replacement, December 2023. Replaces 300 A MRBF with 200 A MRBF. Confirms alternator charging 30 to 100 A on Samkoon. · 24-015 (TSB) Renogy Battery Firmware Update, September 2024. Updates BMS to v137.4.5 to address alternator not charging the battery. Includes state-of-charge calibration. · 24V-160 / 2024-141 (Recall) Renogy Lithium Battery Firmware Update, May 2024, revised August 2024. Recall firmware to v137.4.4. Inspection identifies stuck contactors and requires battery replacement when found. Service bulletins 23-120, 23-123, and 24-015 show that the system ran with outdated inverter and alternator settings, an oversized alternator fuse, and battery firmware that interfered with proper charging. These factors accelerate cell imbalance and degradation. Only after Entegra-approved updates were applied did the full extent of battery degradation become evident. Replacing the battery earlier would have risked repeat failure.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION
I had the same issues as identified in a current recall entitled: Model 907 Sprinter. Model Year 2019-2022 Update Instrument Cluster Software. In my case the instrument cluster remained non-functional upon vehicle start-up exactly like the recall with an added problem of the ignition push button would not shut off the vehicle. I was left with a vehicle I could not shut off without an operational instrument cluster. While my model year and model number match this recall, for some reason my VIN number was not included in the recall so the dealer will not upgrade the software and fix this problem. The scope of this recall must be corrected to include my VIN number.

POWER TRAIN, SERVICE BRAKES
CRITICAL SAFETY CONCERN: Vehicle shifts into NEUTRAL during normal start sequence, could roll over passengers. Component of concern: Electronic "Wiper" stalk shifter is easily shifted into NEUTRAL during normal start sequence. Problem encountered several times in our 2021 Mercedes Sprinter- the stalk shifter is located directly in front of the "START/STOP" ignition button. To start the vehicle, you must: 1) Press and hold the brake 2) Reach under the shifter and press the "START/STOP" button The problem is pressing the brake is also the "safety interlock" for shifting out of PARK. The breakout force on the shifter stalk is VERY LOW, causing it to be inadvertently shifted into NEUTRAL during a normal start sequence. This is a safety concern, because often we will start the vehicle, and then exit the drivers seat to load passengers (small children and/or wheelchair users). The vehicle does not give any indication (no physical movement of the shifter) of shifting out of park- other than white letter on mid-dash indicator going from "P" to "N". The vehicle could easily be shifted into NEUTRAL and run over passengers during the loading operations.

The ABS front wheel sensor became inoperable after 27K. This disables several onboard systems that assist in vehicle control, including blind spot detection, and collision warning systems. Looking at the sensor - it completely separated at the connector by the wheel hub. The surrounding area showed no signs of unusual trauma or deterioration.

UNKNOWN OR OTHER, STEERING, SERVICE BRAKES
I am writing to formally raise a critical safety concern regarding the performance and behavior of the Crosswind Assist system in my 2020 Mercedes-Benz Sprinter 3500, upfitted by Airstream as a B-Class RV. This vehicle, identified by VIN [XXX] , exhibited behavior that I believe constitutes a significant and potentially dangerous flaw in its integrated driver-assistance programming. During a westbound trip from Minnesota to Nevada—traversing high-wind corridors in South Dakota, Wyoming, and Utah—the Crosswind Assist system activated on multiple occasions while overtaking large trucks during gusty wind conditions. The system appeared to override driver input by abruptly applying the brakes and modulating throttle response. On one particular occasion, this intervention forced our vehicle laterally toward a semi-truck in the adjacent lane while simultaneously initiating a hard brake event. This caused not only a near side-impact collision but also a chain reaction behind us, as trailing vehicles panic-braked, narrowly avoiding a rear-end collision. This level of autonomous intervention, especially under highway-speed wind shear, presents what I consider a severe safety risk to occupants and other motorists. No reasonable amount of driver anticipation, route planning, or wind-speed awareness could have prevented the unintended and forceful application of braking and steering commands we experienced. Upon referring to the owner’s manual and engaging in discussions on several Airstream and Sprinter-owner forums, I discovered that other owners have experienced similar incidents. Some users referenced the ability to disable the system through authorized Mercedes-Benz diagnostic software. Based on this information, I scheduled a service appointment at Mercedes-Benz of Farmington, Utah on March 17, service invoice [XXX].

UNKNOWN OR OTHER, STEERING, LANE DEPARTURE: ASSIST
My vehicle is activating “crosswind assist” and applying the brakes automatically, unilaterally, and abruptly while traveling at speeds over 40 mph on the highway, even when conditions are NOT windy. It seems that the sensor is overactive in detecting wind. I have taken it to the Mercedes dealer and they have stated they found no problems with the ESP sensors and state that the vehicle is responding to perceived wind conditions/instability normally and as it should. However, this was NOT like this for the first two years I drove the vehicle. It is DANGEROUS and not normal and the unilateral application of the brakes while I’m going 60 or 70 miles an hour on the highway forces my vehicle out of the lane and into parallel traffic lanes! The unilateral braking is sometimes so severe that my vehicle fishtails and feels like it is going to roll over into an adjacent lane or off the highway. This is going to cause a major accident to me and fellow drivers. Since the problem started six months ago and has steadily worsened, I have been advised to upgrade the suspension and install an “swaybar” and also to change the tires to make the vehicle more stable. I have done both. Neither has helped at all. I don’t know what to do or where to take it. It seems like deactivating the crosswind assist would be helpful in determining if the sensors are too sensitive or defective and whether it drives safely without them. But there is no way to deactivate that system. I have owned my vehicle for three years and for the first 2 1/2 years it drove perfectly, without this issue ever happening. My vehicle has not been in any collision and has had no damage, so I do not know where this came from. It seems like an electrical or sensor issue that has arised and neither a sprinter specialist mechanic nor the Mercedes-Benz dealership with a sprinter technician have been able to figure out what is wrong and how to fix it. This is URGENT and I need help or there will be a catastrophe.

VISIBILITY:WINDSHIELD
Purchased CPO certified Mercedes-Benz 2021 Sprinter Rv Van that was sold to me by Mercedes-Benz of S. Orlando Florida with illegal window and windshield tint and when I complained they stated it’s buyer’s responsibility to pay for removing once it’s sold. It’s a safety hazard as it was extremely difficult to see at night. Police pulled us over for it, but kindly told us to remove it for our safety. The same answer was stated for the significant rust on the roof as buyer had opportunity to view before purchase…..not typical to climb up the roof for seniors. Seems to be a pattern of sales practices that’s deceptive, passing the cost to buyers, rather than to have it corrected before CPO certification.

UNKNOWN OR OTHER, VEHICLE SPEED CONTROL:ACCELERATOR PEDAL
My van has periodic lack of acceleration or dead pedal. There are no warnings that this will occur. This shows itself when trying to advance from a stopped position. When I push the accelerator the van either does not move at all or barely crawls forward. This can last 15-45 seconds. There are no RPMs from the engine. Once the pedal starts to respond, the issue will resolve. The problem is you need to get to that point where the engine can make rated power. Once you put in in drive, and if you're able to idle away from the parking spot, you may find that when you need power to move up a hill or through an intersection, it just isn't there. You can't wait a minute with your foot to the floor when you're in the middle of an intersection. sometimes it will slowly accelerate. This has caused multiple situations where I thought I was going to die due to being out in cross traffic and failing to be able to move. It happens both in reverse and forward. It happens even though I have warmed up the engine for 5 minutes or more. It seems to happen more at altitude but has also happened at sea level. It doesn't seem to matter if the outdoor temperature is warm or cold. The dealer can not detect a problem. I have read many accounts of this happening on MBZ forums. This must be a known issue with MBZ yet they have failed to solve it. Some think it is a sensor initiation issue after a cold soak. Someone is going to die because of this problem if MBZ is not forced to fix it.

STRUCTURE:BODY, UNKNOWN OR OTHER
We purchased a 2021 mb sprinter Van, modified up fitted as a RV with 15842 miles from MBSO Orlando on June 26th 2024. In Idaho on the freeway we were pulled over for illegal tint and while we were not ticketed after reviewing the purchase agreement. He warned us to be careful driving especially at night as it was could be very hard to see and it was certified. It harder to see for me as I have some degree of stigmatization with my eye sight as I am [XXX] which is to be expected. After arriving back in Seattle area where we live and found significant rust on the roof of the van and given an estimate for $16500 by certified mb body shop, I emailed the service manager about the rust and illegal tint that was not disclosed, he basically dismissed it…..stating that I had opportunity to view it and it’s buyer responsibility once it’s sold. The failed to respond adequately as to why they certified CPO the 2021 Van, which was misleading to consumers. This is a serious breach of trust for we were expecting a van had passed safety and structural inspection thoroughly by a brand name known for quality and integrity. Now I am faced with additional expenses which we are unable to bear. Please help us as we relied on CPO inspections to avoid unnecessary expenses on our limited income and now we are trapped in a situation we did not expect. Regards, [XXX] [XXX] [XXX] PS. Dark illegal tint and rust on van after a little over 2 months. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The side door will not open. Either the cable part of the mechanism gets stretched or the rubber tensioners need adjustment or the plastic cable hub becomes detached to the point where neither the interior passengers or someone outside can let the passengers out. Videos discussing this issue have over 29,000 views and there are numerous posts on forums looking for answers. Regardless of cause, when passengers can not get out, it is a safety issue.
