2015 BMW M4

The ABS module, which controls the brake drying feature, is malfunctioning. This BMW feature is designed to lightly pulse the brakes when the windshield wipers are active to wipe water off the rotors for better braking performance. The intervention is supposed to be imperceptible. Instead, the system intermittently applies hard, sudden brake pressure while the windshield wipers are operating. This causes abrupt, strong deceleration that feels like the brakes are slamming on by themselves. The problem occurs in wet conditions when wipers are on. It has happened multiple times and has nearly caused rear-end collisions or loss of control on multiple occasions. This unexpected hard braking at speed in wet conditions creates a significant risk of rear-end collision, loss of vehicle control, or accident, especially on highways or in traffic. The only workaround is to drive without wipers in the rain, which is also dangerous due to reduced visibility. I have not yet brought the car into the dealership to have it inspected but I do intend on getting that done within the week. There are no warning lights or messages to suggest there even is a problem.

The instrument cluster display no longer functions. Unable to see odometer. Unable to see any vehicle warnings such as fuel warnings, airbag warnings, adas warnings. If I am unable to utilize the instrument cluster display it puts myself and others in harms way as if there is an issue with the vehicle or a warning, I would be unaware as there is no way for that information to reach me. The issue has been confirmed with a code of : B7f694 The display back lighting has failed. BMW states this out of their warranty/workmanship coverage. Leading up to the display failure, the display would cut in and out.

The BMW OEM intercooler/charge air cooler is a known faulty equipment issue within this generation of cars/engine (S55 Engine, F80, F82, F87 chassis) and I have thousands of people within the community that were affected and willing to attest to this. This issue is a safety risk as having the intercooler leak coolant into the combustion chambers this will be a catastrophically damage the engine. As I've mentioned this problem has been confirmed by dealers and independent service centers, and I have thousands of people in the willing to attest to this being a very common issue in this generation of cars. There is usually supposed to be a service warning/check engine light that comes up on the car when there is a coolant leak, I received nothing. The symptoms I've experienced are as the following: My radiator fans kept coming on after drives, I had to physically check that coolant was in fact leaking and the reservoir being bone dry within days, I scanned my vehicle for codes and of course the coolant leak code came back.

I TOOK MY CAR IN FOR SERVICE ON MARCH 10, 2020 FOR SERVICING. DURING THE TIME THEY HAD MY CAR, THEY REPLACED MY FRONT AND REAR BRAKE PADS, COMPLETED THE INSPECTION, AND GAVE ME THE CAR BACK AFTER A COUPLE DAYS. ON APRIL 10, 2020, I TOOK MY CAR INTO SERVICE AGAIN AS I WAS HAVING DRIVE TRAIN MALFUNCTIONS CONSTANTLY. SEVERAL WEEKS OF BEING IN THE SHOP, BMW SERVICE TECHNICIANS FOUND THAT COOLING FLUIDS HAD LEAKED FROM MY TOP MOUNTED INTERCOOLER, INTO THE INTAKE MANIFOLD AND THROUGH THE INTAKE VALVES, AND DIRECTLY INTO THE ENGINE OF MY VEHICLE. SINCE THE ENGINE NOW NEEDED TO BE REPLACED, BMW OF FREMONT RECOMMENDED AND REQUESTED FOR AN ENGINE REPLACEMENT BUT BMW HAD REJECTED IT AND STATED THAT THEY FOUND SOME 'TUNE' IN THE VEHICLE. I PURCHASED AN EXTENDED WARRANTY AND MAINTENANCE PLAN FROM BMW DIRECTLY THAT IS STILL ACTIVE. MY ENGINE REPLACEMENT SHOULD BE COVERED UNDER WARRANTY BUT BMW IS NOT ADHERING TO THAT WARRANTY. AFTER COUNTLESS CALLS AND EMAILS BEING SENT BACK AND FORTH BETWEEN ME AND BMW, NEW INFORMATION AROSE STATING THAT BMW FOUND THAT THE 'TUNE' FOUND IN MY VEHICLE WAS MERELY A VALVE CONTROLLER FOR MY EXHAUST SYSTEM. BMW OF FREMONT CLEARLY MENTIONED TO BMW THAT THIS LEAK IS NOT CAUSED BY OR EVEN REMOTELY CORRELATED TO THE VALVE CONTROLLER, AND THAT THIS ISSUE IS MECHANICAL, NOT SOFTWARE RELATED. CLEARLY, THIS HAS NOTHING TO DO WITH THE MAJOR ISSUE AT HAND, WHICH IS THE LEAKING INTERCOOLER CAUSING MY ENGINE TO FAIL. IT IS A MAJOR SAFETY ISSUE FOR MY CAR TO BE RUN WITHOUT THE ENGINE REPLACEMENT, AS THE CAR NOW HAS A MUCH HIGHER CHANCE OF BEING HYDRO-LOCKED. MY CAR HAS NOW BEEN AT BMW OF FREMONT FOR THE PAST TWO MONTHS. I'M STILL PAYING MY MONTHLY DUES FOR THE VEHICLE DILIGENTLY EVEN THOUGH BMW HAS CAUSED THIS MANY ISSUES. *TR

The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle “discharged battery” complaints.

With the vehicle is on a lift and the front struts are in the extended position, there may be a cracking and orclicking type noise when turning the steering wheel left/right. See attached video V31 01 24. The sound can reoccur when the vehicle is lowered, and the wheels are once again under load. The noise might also be heard for a short time while driving.

Functional noises (squealing/honking) when braking shortly before the vehicle comes to a stop. CAUSE Material-

After programming the head unit (HU-H2), activating the FSC (German word Freischaltcode) Enabling Codes repeatedly fails.

Upon opening and closing the tailgate, a creaking/groaning sound can be heard from tailgate actuator.

Exterior rear lights do not work.
