2021 BMW X5 Electrical Problems

The drivetrain warning light came on shortly after I started the vehicle. I noticed acceleration issues both while driving on side streets and on the freeway. I took the X5 45e into the repair center the day after the notice came on especially given the experience on the freeway, which happened during rush hour traffic. Upon inspection, I was told the starter was beginning to fail and that while there had been a recall on starters on many other BMW models, it did not include the X5 45e. BMW advised I replace the starter immediately due to safety, which cost $2,600. Two weeks later, the same drivetrain light has come on and the X5 is back at the service center for diagnosis.

2021 BMW X5 xDrive45e PHEV, built October 2020 by BMW AG (Germany). In-service Oct 28, 2021. Vehicle intermittently shows "Drivetrain Malfunction — you can continue driving" warning. DME scan reveals 5 fault codes, all for the conventional 12V pinion starter: 21A50A — Pinion starter: timeout occurred several times in succession 21A511 — Pinion starter: timeout 21611A — Pinion starter: starting torque could not be built up; high counter torque and/or undervoltage 216119 — Pinion starter: line break in starter control (KL50/KL30) 216115 — Pinion starter: attempt to start with blocked starter detected 21A50A and 216115 are protected memory codes that cannot be cleared by standard OBD-II tools. The main 12V AGM battery was replaced and registered; codes continue to recur. This signature matches the B58 pinion starter defect addressed in NHTSA Recall 24V-576 (Aug 2024) and 25V644 (Nov 2025, physical starter replacement). The vehicle's German manufacture date falls inside the production windows of KBA recalls 15630R, 15632R, and 15633R — all covering X5 G05 for short-circuit and fire risk from starter relay corrosion or inadequate mounting. BMW AG has issued an ADAC advisory not to leave affected vehicles running unattended after starting. BMW NA Customer Relations was contacted. Initial verbal response: U.S. recalls don't apply because the xDrive45e PHEV uses a different starter than non-hybrid B58 vehicles. However, codes 216115 and 216119 only exist on vehicles equipped with a conventional pinion starter — confirming this vehicle has the same component. The subsequent written denial pivoted to warranty expiration without addressing the technical or recall-scope questions. Filing so the field record reflects this defect signature for future U.S. recall scope expansion analysis.

A drivetrain malfunction warning, chassis warning, auto level suspension was locked, and check engine light was on while driving on the freeway. We made it home safely and parked the BMW X5 45e inside the garage. I plugged in my charger and was not able to charge. Went to start on electric mode/hybrid mode but was not able to turn on. Then I switched to sport mode via gas and engine started but stuttered, and was unable to switch gears from parking to reverse or to forward. Engine continued to shut studded and then engine and electrical completely shut down. I will contact BMW Riverside on Monday.

Similar to the incident described in [XXX] , BMW has refused to assist with repairs related to defective vehicle cupholders, causing the headunit wiring to short out and fail. This also causes any number of safety items to become unavailable as well. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In the middle of a busy intersection, the car just completely shut down. The car only had ~35,000 miles on the odometer and has been serviced only by BMW. It turned out that the water pump broke, which led to downstream impact on additional surrounding systems. BMW X5’s up to model year 2019 had recalls due to faulty water pumps. From an independent search online, it appears there are many owners of 2021 BMWs who have experienced water pump failures like I did. This could have led to a major safety incident as my husband nearly avoided an accident. If this had occurred suddenly on a highway, for example, that could have resulted in a multi-car accident as the car very suddenly died and came to a stop.

The starter for my 2021 bmw x5 recently went bad and had to be replaced. The defect with the starter ruined my battery as well. Leading up to the starter not working, I received warning messages that the car could not be driven. The BMW representative at United BMW (Alpharetta, GA) stated the starter issue seemed to be a problem as many were needing to be replaced. I am submitting this information because of the recent recall related to the 2020 model staters. It seems it should be investigated whether the 2021s also have problems.

Good Morning, I was driving down the road at around 60 mph in my car. Abruptly my car had simultaneous warning lights about 12 of them. More importantly, I lost my power steering and brake by wire putting all of our lives at risk. The speedometer , air bags, restraint systems all failed and went out. The car wouldn't turn off on the side of the road and after about 5 minutes I was able to get it off and called BmW assist for a tow. Since it was night and raining I and waiting for a tow truck was dangerous I attempted to restart my car and get successfully got it to the nearest exit. All the warning lights were off. About 15 minutes later on the limp home the same thing happened with all the fault codes so my family decided to Uber home. I took the car to BMW Rockville and they did diagnostics and we're not able to replicate the problem. They returned my car back to me the same day with no repairs. I'm concerned. There was no indication or warning lights before the electrical failure. It was completely out of the blue.

While driving about 60 mph on a freeway, the vehicle rapidly flashed several "advanced driver system failure" messages, lost all power and came to a stop. It was not possible to prevent the vehicle from rapidly decelerating even by depressing the accelerator all the way to the floor. The vehicle rapidly decelerated, forcing other drivers behind to swerve to avoid a crash.

Previously reported that the BMW X5e, Plug in hybrid, shuts itself off once the driver's door is opened leaving anybody in the car at risk of serious health problems or even death! A menu selection option should disable this unsafe practice but it does not work. As if there is a software glitch. Other models, the X3e stays on when the driver's door is opened. I've previously reported this item but now my father has injured himself recently. After a medical appointment and retrieving his medications my father was in the car in unsafe and deadly heat and attempted to exit the vehicle due to the car shutting itself off and he fell and hurt himself. The manufacturer has been contacted several times and at times they say this should not be happening but the dealers are saying that is how the vehicle is designed. I also have videos of the other models not shutting off for review. PLEASE FIX THIS ITEM!
