What owners say about the engine
Verbatim from NHTSA complaints, newest first
“The contact owns a 2013 BMW X3. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power with the check engine warning light and drivetrain warning light illuminated. The vehicle failed to restart and was towed to the dealer. The dealer diagnosed that the positive battery terminal motherboard had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was later towed to an independent mechanic, where it was diagnosed that the engine had failed and needed to be replaced. The vehicle was not repaired. The dealer was not contacted again. The manufacturer was made aware of the failure. The approximate failure mileage was 106,000.”
“BMW knows there is a problem with the 2013 x3 timing chain. I have continuously had my BMW serviced at there shops. Never once when my car was in for service did they mention the issue or proactively check. My vehicle now has the issue per the dealership snd indicated it is approximately a 20k repair which they included a new engine. I also followed BMWs recommendation to have the oil changed 1year or when miles were hit per their change program. Just has the oil changed in November and at the end of December now timing chain issues. Again multiple times this issue could have been identified and proactively fixed while under warrenty. Also has issues where the material on the glove box peeled off. BMW is also aware of this issue. Poor design and quality on these models/engine. Thank goodness i was not on the expressway when drivabilty issuev occurred!!!”
“While driving my 2013 BMW X3 xDrive28i under normal conditions, a “drivetrain malfunction” warning suddenly appeared, immediately followed by a “low oil pressure” warning. Within seconds, the engine lost all power and shut off completely while the vehicle was in motion. I had to coast and steer the car off the roadway and push it to safety with the help of others. My safety and the safety of other drivers were at risk due to the sudden and complete loss of propulsion in active traffic. An independent BMW-trained service center confirmed that the engine suffered catastrophic internal damage caused by failure of the timing chain system. This timing chain defect is well documented in BMW’s N20 engines and is the subject of a class action lawsuit. The vehicle is now completely undriveable and remains at the repair facility. Engine replacement is the only option and is estimated between $12,000–$15,000, far exceeding the value of the vehicle. The failed engine and vehicle are available for inspection upon request. The problem has been reproduced and confirmed by an independent BMW specialist. BMW has not yet inspected the vehicle, although I did call and report to…”
“I own a 2013 BMW X3 equipped with the N20 engine. After approximately 17 months of ownership and only around 11,000 miles of normal driving, the vehicle suffered a sudden and complete engine failure without warning. The independent diagnostic determined the failure was due to a timing chain and oil pump drive chain defect, which is a well-documented issue in BMW N20 engines. This defect has been acknowledged by BMW through Technical Service Bulletin SI B11 03 17 and the national class action settlement Bang v. BMW of North America. The defect causes premature wear and eventual breakage of the timing chain components, resulting in catastrophic engine damage. My vehicle is now inoperable, and the cost to repair exceeds $7,500 — far more than the vehicle’s value. There were no prior warning lights, noises, or messages. This sudden engine failure creates a safety risk, as the vehicle could lose power unexpectedly while driving. No authorized BMW dealer had ever performed timing chain replacement on this vehicle, and the issue was not disclosed at the time of sale. I am filing this complaint so NHTSA is aware of the widespread nature and serious safety implications of this defect.”
“The contact owns a 2013 BMW X3. The contact stated that while operating the vehicle, there was smoke coming from under the hood of the vehicle, and there was oil leaking from the engine compartment. The vehicle was taken to the local dealer who diagnosed the vehicle and determined that the engine gasket was faulty and needed to be replaced. Additionally, the contact was informed that the subframe of the vehicle was rusted. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 134,000.”
“Purchased a used bmw x3 2013 about 2 years ago in may of 2023 since the beginning it was smoking and almost caught fire. I did open a case with the dealers commission / dmv to go after the mom and pop seller. But it was unfounded thankfully. It was at the dmv facility for a few months. Once it was unfounded in January of 2024 we immediately had it towed from the dmv inspections to bmw in Warwick . Where we were at first told it was a $5000 fix ( book value was only $9000 which we had paid $8000) then told it was a $7000 fix ended up being a $12,750 fix I was mortified but already too far in to do anything we were assured once the car came back it would have no lights on the dash and everything would be fixed and under warranty if anything did go wrong needless to say it took us months to come up w the $ that car sat there till may of 2024 as they was about 1/3 of my salary for the whole year . Needless to say we were paying monthly which was ok’d by the dealership . Once my wife went to pick it up immediately all lights were still on dash all same code service rep wasn’t there that day had to bring it back the next day for them to tell us it was something else…”
