2018 BMW X3 Complaints

While reversing heard a clanking noise (like a heavy wrench falling off from few feet). Came out and checked and found a broken piece of suspension coil spring near the front left wheel. Checked the inner portion of the coil with hand and felt uneven surface on the lower part of the coil similar to the unevenness on the broken part. Remaining coil is still hard to move and seems to be in place. Car is only 6 yrs old and driven for less than 35k miles. Asked around with local shops and they say with this age and miles it should not crack like this and could be a quality issue. No rust is visible and remaining part of coil looks intact. Please check photo as well.

The contact owns a 2018 BMW X3. The contact stated while his wife was driving 65 MPH, a message advising to stop driving was displayed, and the vehicle simultaneously shifted into neutral(N) independently. The vehicle stalled in the middle of the highway and failed to respond while depressing the accelerator pedal. The message advising to drive with caution was displayed after several minutes, and the contact was able to continue driving upon depressing the accelerator pedal. The vehicle was taken to an unknown dealer to be diagnosed. The vehicle was not diagnosed or repaired. The vehicle was then towed to the local dealer, where it was diagnosed that coolant was leaking from a hose. Additionally, the dealer informed the contact that excessive engine temperature could have damaged the cylinder head and the rod bearings. The dealer recommended replacing the engine. The vehicle was not repaired. The contact stated that his son-in-law then towed the vehicle to another facility, where the vehicle was diagnosed by a mechanic; however, no engine failure or coolant leak were found. The contact related the failure to an unknown recall. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 152,942.

2018 BMW X3 M40i - after the car was washed in a car wash, the tailgate started opening and closing on its own. Would open all the way up, wait a few seconds then close all the way down and lock itself. It happened about 20 times until it stopped on its own. This started immediately after the car was parked in the garage. Did not happen while driving. The button on the remote control was not pressed at all. The tailgate would beep and flash the taillights when opening and closing.

The oil filter housing, which is made of plastic, cracked while the vehicle was running on the highway, leading to sudden loss of the all the coolant and engine overheating.

Something is wrong with the BMW OEM windshields with HUD. I have had to completely replace 3 in 5 years. In between replacements have had Safeliite try and fill pits in it. My last windshield lasted 21 days before cracking on the side at the very edge. I was driving and the road construction had very uneven lane heights so the car was higher on the passenger side. All of the sudden I heard a crack. The was not rock or debris that hit the windshield. There have been lots of complaints about the BMW windshields with HUD especially the X series SUV’s. People are saying softer glass. All I know is this is dangerous and BMW is up charging for replacement windshields if you don’t have insurance or a warranty. The cost is in the thousands for the replacement. I’ve never had a car that had such issues with the windshield being damaged so easily and or faulty glass. My last windshield replacement was 6/29/23, cracked 7/20/23

The trunk on the vehicle can be opened while on the freeway. If you bump the trunk open switch or key fob button the trunk will open even when the car is in motion leading to personal belongings being thrown all over the road. This is a massive issue that should have been caught and fixed immediately.

I am writing to report a potential safety problem with my 2018 BMW X3, VIN: (provide VIN here if available), that was purchased in May 2018 and has covered 36,000 miles since then. The vehicle has always been garaged and well-maintained. A few weeks ago, I experienced a critical malfunction with the vehicle's moonroof. I opened it normally, but it failed to close afterwards. I should note that this was merely the 4th or 5th time I have ever operated the moonroof since the car was purchased. As of now, the moonroof remains in the open position unable to close it even manually. With summer on the horizon, the interior of the car is exposed to direct sunlight and increasing temperatures. This situation raises significant concerns for my family, particularly the potential health risks to my 7-year-old daughter due to prolonged exposure to excessive heat and sunlight. Upon experiencing this issue, I contacted the service department for troubleshooting. The technicians diagnosed the issue as a problem with the interior sunshade motor, an electrical issue that necessitates a labor-intensive process to fix, including the removal of the vehicle's headliner. Subsequently, I reached out to BMW North America, seeking support and resolution for this significant malfunction. To my disappointment, they declined to acknowledge the problem or offer any assistance towards remediation. This response was unexpected and unsatisfactory, considering the potential health risks and safety concerns the malfunctioning moonroof poses to occupants of the vehicle. I respectfully request your department to investigate this matter and take appropriate action to protect the safety and wellbeing of consumers who may be dealing with similar issues. This may well represent a widespread manufacturing defect that could affect numerous vehicles of the same make and model, thereby posing substantial risks to a large number of people. Thank you for your attention to this matter. The contact stated that the manufacturer initially told them that th

First Failure 3/22- Vehicle makes clanking/rattling of metal sound when going over bumps. Sound is felt near driver caliper and rattles. Can be felt in steering. 4/22 Vehicle is taken to BMW for inspection; needed to come back as they couldn't figure it out. 5/22 Vehicle sound is replicated by BMW dealer service center. I have not received any warning messages or lights prior. Current lights that stay lit longer than usual are the assisted driving and the hazard. This has been since the power failure however. Vehicle has been out of service for a collective 150+ days this year. No remedy to to issue. 11/22 Car broke down again on the highway; extreme shaking, bouncing, loose and uncontrolled steering. 12/22 Car back in service and immediate rattle under front driver's side, loose steering and wobbly tires. Electrical failure, no start and all dash lights glowing. (possible battery issue). 1/23 Car is back to BMW for further inspection. No information yet I believe safety and others is at risk because there have been two times that I was driving and the car felt that is was not controllable. The BMW service center has had it in their garage 5 occasions without remedy. One certified mechanic has been unable to diagnose as well. Parts repaired: Struts, Guides, Swing Arm/Sway, Both front lower control arms, tires and drivers side CV axle.

The contact owns a 2018 BMW X3. The contact stated that while driving at various speeds, the forward collision avoidance feature would be active without incident. The contact stated that both the warning chime would sound and a red alert warning light would appear on the instrument panel during the failure. The contact also stated that while driving at 35 MPH, the vehicle came to an abrupt stop as the forward avoidance collision feature activated. The contact stated that both vehicles were more than a vehicle's distance apart and that the feature should not have been activated. The dealer was notified about the failure and informed her that they were aware of the matter; the contact was then given an appointment for a diagnostic. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was unknown. The contact stated that the failure mileage was 13,600.

* Components: Per dealership, Heat exchanger (metal) and oil filter housing (plastic), oil filter housing supports the heat exchanger, vehicle inspected by dealership and available for further inspection. *Vehicle unexpectedly overheated while driving on interstate risking the safety of driver/passengers and others. Dealer's (manufacturer) technician stated that the heat from the metal exchanger warped the plastic oil filter housing causing coolant to leak from heat exchanger, thus not allowing coolant to circulate to engine (leaking out) and causing vehicle to overheat. Metal warping (or potentially melting) plastic seems hazardous *Dealer's technician (manufacturer) inspected and identified the problem and quoted a cost of $3,140.80 to repair (this is seemingly a manufacturer's design flaw). Vehicle's warning system displayed an alert that coolant level was low while driving on interstate and recommended adding coolant soon. Driver pulled over within 5 min of warning light and added coolant. Within 5 min of driving away, Vehicle's onboard warning system displayed warning that vehicle coolant was low and engine temperature was elevated but it was safe to drive a low speed and consult nearest dealership, 2 min afterwards, vehicle alerted driver that engine overheated and to stop vehicle and contact nearest dealership. Vehicle towed to nearest dealership.
