2017 BMW 3 Series Engine Problems

The contact owns a 2017 BMW 320i. The contact stated that while his son was driving 35 MPH after an oil change was performed on the vehicle, the message "Engine Temperature High. Drive Moderately to Cool Engine. Consult Service Center" was displayed. The vehicle was towed to the same independent mechanic, where an unknown diagnosis was made. The vehicle was not repaired. The vehicle was towed to the dealer, where it was diagnosed that the water pump electrical connector and wiring were corroded, fractured and needed to be replaced. The vehicle was not repaired. The vehicle was then towed to another dealer, where it was diagnosed that the water pump and the electrical connector needed to be replaced. The contact related the failure to an unknown recall. The manufacturer was notified of the failure. No further information was available. The failure mileage was approximately 94,000.

My BMW has had multiple repairs (3 incidents - 2 times repaired by BMW and 1 time repaired by a national mechanic garage) to the coolant system since I purchased it in 2018. BMW have verified the leaking coolant as well as the independent garage. Currently, the coolant system has another on going issue where it is still leaking and it's still unable to be fixed. This coolant issue has had catastrophic failures at times and more recently it has thrown a major engine overheating warning that has impacted the safety of my wife, kids and I as well as other individuals on the road as I have had to pull over quickly and turn the car off to allow the engine to cool down. I've had to drive the car at a reduce speed and acceleration which has frustrated many drivers causing them to over take me dangerously. Additionally, I've burnt my hand from opening the coolant expansion tank to add coolant on multiple occasions.

I noticed coolant leaking from under the vehicle. The message to add coolant was displayed. The vehicle was taken to an independent mechanic where the engine was inspected, and was notified of stains of coolant coming from the head gasket. The contact was informed that the head gasket needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. I believe this is failure is related to NHTSA Campaign Number: Recall 18V755000, October ,24 2018, My car has only 73000 Miles

The contact owns a 2017 BMW 330I. The contact stated while driving at an undisclosed speed, the low coolant warning light illuminated. The vehicle was taken to an independent mechanic, who determined that the vehicle was consuming and excessive amount of coolant. The contact stated that the coolant reservoir was empty after being refilled the previous morning. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 18V755000 (Engine and Engine Cooling); the VIN was included, and the vehicle was already repaired under the recall. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was unknown.

Oil filter housing and or oil cooler failed. Leaking internally and externally. May cause fluid to leak on to hot engine and cause potential fire or short circuit wiring.

UNKNOWN, it has problems with stalling and starting up could be issues with the internal drive system that I’ve seen other types of similar models of bmw having these recall issues as well. When starting up after fueling up it over exerts the engine trying to start up. You kind of have to rev it to start it up. And driving it after that it has trouble keeping a solid drive.

The vehicle had a recall on the engine coolant valve line which was taken care of by BMW dealership on November 1, 2024. In less than a month later, an issue has been noted of coolant leak which caused the engine to overheat causing a safety issue on the road while driving my kids to school. The service manager advised that the issue is not part of the open recall that was already done on November 1st. How can a recall for the same concern of coolant leak and engine over heat cover only one hose where the issue could be related to another hose connection?

On yesterday i went to the Bmw dealership for service. once i got there i reported that i been smelling a burning smell coming from underneath the hood. well the technician can back and reported i have 3 leaks. i was told i needed to replaced EG58 Gasket oil Filter housing, EN17 cylinder head cover Gasket. i need to know if my 2017 Bmw 320i have a Recall on this matter. i believe in 2022 from what i read today.

This is my second BMW 3 series. Both of my BMW 3 series have flaws in cooling system. Within 7-year of purchase, it has more than 7 leaking issues. In 2019, it has water pump issue In 2020 it has evaporative emissions vent purge valve issue In 2022, it has cooling system hoses leaks In 2023, it has cylinder head leak In 2024, it has coolant leaks, oil filter leaks, and front struts leaks. All these are related to a failed cooling system and overheating engine.

Persistent Low coolant warning issue, Coolant leak was discovered to be coming from Oil filter housing. This is a $3000 repair on something that should last at least as long as the engine. If there are others with this problem, Then maybe a recall is due. Dealer is repairing now at my expense.

BMW B48 engine. Coolant started leaking and the engine overheated. Unbeknownst to me caus the bottom of the car is covered. I had a mechanic look at it. Found the leak coming from the "oil filter housing unit". When he removed it it was broken at one of the 6 ports inside with the pieces missing presumably fell into the interior of the engine. BMW manufactured these units out of a composite material and not aluminum I assume to save costs and weight. This composite material has failed in many of their engines including the mini cooper. When I looked on line googling it I was shocked at how wide spread it was. It's a costly repair about 2000-2500 for parts and labor. This composite material is also used in their failing water pumps all the failing coolant hose connectors and more I believe.

Coolant Leak from oil filter housing caused a major repair. The Car has about 109,000 miles. Parked it after work on a Thursday went to drive it to a family dinner Friday, i turned the car on and immediately get a low coolant light. I drove 2 miles down the road, Suddenly the coolant started pouring out and the coolant light comes on again, i return home and have to take my girlfriends car. On the invoice it states, “entire oil filter housing part was replaced”, the plastic used to seal in the coolant had either been destroyed or broken off, not a gasket but a piece from the oil filter housing part. The dealer charged $4500 for the repairs, which they said were “optional” but the engine couldn’t hold coolant. This item is not on the recommended service list, as it’s not an item listed for “wear and tear” However the B48/58 engines are so new that finding enough over 100K miles is not easy to replicate the issue, although message boards have recently discovered this issue occurring with more regularity. Please investigate and help consumers who potentially could be left stranded by this defect.

In November of 2023 I was driving my vehicle on the highway when my vehicle's control panel notified me the engine was over heating and I needed to stop driving the vehicle immediately. All the engine coolant had leaked from my vehicle. I had to pull over on the highway and have my vehicle towed. My mechanic identified the problem as the coolant vent line and made the repair. Total cost was $2,052.16 including the tow. A few months later a message from BMW came up on my vehicle's computer display saying there was an "Important recall or campaign", a service action for the exact repair I paid $2,052.16. They now refuse to reimburse me because it is not labeled a "recall". This issue is widespread and needs to be labeled a recall for consumers. A known defect since 2022 that I was never notified prior to the incident and now they refuse to reimburse me for a know defect in their product. I believe this violates my rights under federal consumer protection laws. Please help the consumers and force BMW to label this safety issue a recall and stop hiding behind their euphemisms

The plastic oil filter housing assembly developed a crack as we all should know heat and plastic do not do well with each other. Cause my coolant at first to slowly leaked and never gave me a warning of low coolant. Driving 60+ mph then all of a sudden cars goes into limp mode so the person behind me lucky swerved to the left to avoid hitting me. So filled up coolant and same thing happens again about a week later. No visible leaks no dashboard warning of low coolant levels. So I fill up and go. Mind you my engine is already overheating when it tells me on dashboard while going into limp mode at the same time so continuously overheating engine seems to cause more problems water pumps starts leaking and pipes start developing holes. Safety comes into play while driving down a highway when car goes into limp mode causing the driving that’s not paying attention ram into you. Quite a few safety concerns. Never had a chance or opportunity to pull over to self diagnose, car goes into limp mode with no warning. There are several thousands of this reporting the same with oil filter housing assembly. As I am writing this my mechanic is in the process of taking the part off and replacing it with a metal one. This first happened around thanksgiving 2023 and progressively got worse with each week

Coolant Leak caused a major repair. The Car has about 90,000 miles. Suddenly the coolant started pouring out. As you see in the attached invoice, entire heat exchanger, water pump, and other several parts were to be replaced. The dealer first estimated the repairs at $5,400 and they agreed to do it at warranty price rates. However, we believe other BMW models have had similar recalls for Coolant leak and suspect same on this model too. Please investigate and help consumers who are ending up paying exorbitant amounts to service shops. BMW may be hiding this problem from NTSB to avoid recalls by agreeing to repair at vehicle warranty rates.

The contact owns a 2017 BMW 320I. The contact stated that while starting the vehicle, the contact stated that there was white smoke coming from the exhaust tip. The contact related the failure to Technical Service Bulletin: SI B11 11 16 (N20 Engine Oil Feed Line to The Turbo Charger). The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 87,000.

My BMW had a pinhole in the radiator caused by driving on the highway and being impacted by a small foreign object. Apparently a foreign object (rock?) impacted the radiator creating a tiny leak. BMW repaired the vehicle (new radiator) and installed a "Rock Guard" without discussing this new Guard with me. Rock Guard Part # 17-11-8-185-042. This $1,900 repair is a known defect in the design which is why BMW adds the Rock Guard when replacing radiators. After the repair, research indicates this is a common issue for this model car. Loss of coolant could have resulted in an overheated engine leading to vehicle damage or possible failure of the engine while driving. There were not any warnings provided by the vehicle's systems due to the loss of coolant from the pinhole in the radiator. The symptom that lead to the discovery was the air conditioning system stopped cooling. The loss of the ability to cool the engine stops the AC from working. Taking the car in for service for the AC is what lead to the discovery of the leak in the radiator.
