Component or system that failed/malfunctioned N63 4.4L twin-turbo V8 engine – excessive oil consumption (1 quart every 300–400 miles) caused by failed valve-stem seals and leaking turbocharger coolant feed/return lines. Parts are still on the vehicle and available for inspection. How was your safety or the safety of others put at risk? Sudden loss of engine oil can lead to catastrophic engine failure, bearing damage, or fire. Leaking coolant onto hot turbochargers creates risk and sudden coolant loss/overheating while driving. Has the problem been reproduced or confirmed by a dealer/independent service center? Yes – confirmed by Paul Miller BMW Wayne, NJ on June 30, 2025 (invoice #524818).

The primary component that has malfunctioned is the engine's valve stem seals, which are available for inspection upon request. This defect has led to excessive oil consumption, which has now escalated to a critical safety issue. The vehicle is emitting a huge amount of thick smoke from the exhaust with a strong smell of burnt oil, and multiple engine warning lights are illuminated. I have stopped driving the vehicle, as the excessive smoke creates a significant visibility hazard for myself and others, and the underlying issue presents a risk of sudden engine failure. The problem has not been formally confirmed by a dealer, as the General Manager at BMW of Rockville dismissed the repair as not "worth fixing." It is important to note that BMW has been aware of this N63 engine issue and created a Customer Care Package (CCP) to address it, yet I was never notified, despite regular service at authorized centers. The vehicle has not been inspected for this specific safety concern by the manufacturer or others. The initial symptom was excessive oil consumption, which has been ongoing for some time and has now worsened to the current safety-critical state.

1) The power steering completely failed without any warning as a result of the serpentine belt failing catastrophically. 2) The failure happened in rush hour traffic right as the light turned green to turn left on an extremely busy intersection. I couldn’t turn the wheel and was a few inches from a head on collision with several large trucks which were also turning to the opposite direction. 3) The service center explained that this issue is the most common that they see on bmws with the same engine. They alleged that BMW used a faulty power steering bolt that would leak fluid onto the belt, eventually leading to catastrophic engine failure due to the shredded belt being sucked into the crankshaft seal. 4) Yes. 5) The steering was heavy but the bmw dealer assured me the vehicle was in excellent shape just a few weeks prior to this incident.

Car was purchased in July of 2017. Extended warranty was purchased. Dealership says they do not have that in their records. A letter was sent to our address regarding extended coverage, but had another person's name on it. Regardless, the engine developed excessive oil leaks, and led to complete engine failure. Dealer says it would be several thousand dollars to look at it. Research indicates that this model vehicle had excessive oil leaks, but we were not apprised of this, or any of the recalls when purchased. Also, the seals were not holding oil. Dealer sold the car without disclosing of any of these defects. Further, I believe there may have been a recall on the engine, but BMW tells us that this engine is not in the recall. Additional research conforms that this is a standard practice for BMW. I can be reached any time at [XXX], or [XXX].

As I was exiting a public Starbucks parking lot near my home with my foot on the brake slowly releasing it (as I had a car in front and behind me) my 2013 BWM X5 accelerated on it's own. I quickly glanced at the pedals thinking I might have stepped on the accelerator instead of the brake, but no. My foot was on the brake. I stomped on the brake as hard as I could while the vehicle was jerking and stalling. The car in front of me exited the parking lot and luckily I didn't crash into it. This kept going for about a minute it was as if I had been stepping on the accelerator and brake at the same time. I tried turning off the vehicle, but nothing happened. Finally, after about a minute (or maybe a little more) the engine turned off and the car stopped moving. There was an ATM the right of me with a few people making line. They offered to help me push the vehicle out of the way as I was blocking a very tight parking lot exit, but I was unable to put the car on neutral, drive or anything. I was in shock and very scared of what had just happened. I had my car towed to the nearest auto repair shop where I explained the situation the the auto repair people. I was advised to call BWM as the repair shop was unwilling to give me a diagnosis due to the nature of the incident. I called BMW of North America, reported the incident and after about 2 weeks BWM had my vehicle towed to BMW of San Diego where an investigation was going to be done. After 3-4 weeks I received the results. Since the engine did not start they could not find the cause of what made the vehicle accelerate on it's own in such a way. They did have other irrelevant findings like an after market oil filter and debris in the oil. The final report was that the engine had to be replaced. I asked for an estimate from BMW and they came back with $20,993.50 (which is more than what I paid for the car). Even if I was to replace the engine, I don't trust the car anymore. BMW of San Diego is holding my car as a courtesy.

Engine failed because the crankshaft got so hot it fused the crankshaft and the bearings causing the complete failure and replacement of the engine. Bmw has had numerous claims of engine failures in the x5 but they will not do anything to repair the vehicle. The engine only had 84k miles and then without warning, no oil leaks, no hot engine red lights, nothing at all to speak of in the middle of travel, the engine completely shut off and I have to do everything to get to the shoulder of the road. The bmw dealership in bay shore ny had the vehicle for three weeks and really didn't open the engine up to find the cause. After bmwusa said they would do nothing to resolve their latent defect in the engine obviously metal parts which we came to the conclusion were inferior, I had the engine taken out by a certified trained a mechanic. He stated he has never see a meltdown of parts which welded together from the extreme heat of the engine. No leak were detected for either coolant or oil yet the engine seized simply for the fact, the metal used internally is inferior. For the price you paid for the "ultimate driving machine", bmwusa needs to step up and be honest above the problems that have plagued their engines and their cooling system. I have spend over $15,000 to get this vehicle repaired and bmwusa should reimburse me because of it's known history. I have owned bmws since 1992 and the vehicles lasted passed 175k miles. To have a major engine fail at 84k speaks volumes to the lack of integrity for the engine. Bmw is using steel and metal that have significant strength problems as documented by all the complaints I have read above. To have the engine seized like this is the middle of traffic endangered me and my passengers and totally unconscionable.*dt

After 65,00 miles while driving the engine locked up and will not run. The car did not have an oil leak or excessive consumption, but heavy black soot was emitted from the tail pipes enough that has turned the rear tailpipe surround black. I had bmw dealer look at this twice and they found it to be normal. A new engine is 23,000
