| Engine And Engine Cooling problems |
I was driving home after picking my son up from school and out of no where the vehicle temperature was in the red and a message popped up stating that vehicle coolant needed to be replenished but that continued driving of the vehicle was ok. It was not ok at all! the car started smoking and we were left stranded on the side of the road. I’ve read numerous blogs showing that the same thing has happened to other people and that there have even been recalls on other BMW’s in regards to the engine coolant system.
The contact's wife owns a 2018 BMW 530i. The contact stated that while driving at various speeds, the check engine warning light illuminated. The contact refilled the coolant reservoir, and the warning light turned off; however, the check engine light soon returned. The vehicle was towed to a dealer where a diagnostic test discovered that coolant and freon had leaked from the turbo lines, causing damages to the oil housing and water pump. The dealer provided the contact with an estimate for the repair. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 105,000.
The oil filter housing has a plastic coolant passage that cracked. That lead to a complete loss of coolant, leaving my teenage daughter stranded. The problem seems pretty wide spread on these cars and happens right around the end of the warranty period. It could have been a more than $2500 repair. I ended up fixing it myself for a little less.
The contact owns a 2018 BMW 530i. The contact stated that while driving at various speeds, a coolant level message was displayed on the instrument panel. The vehicle was taken to a dealer where a diagnostic test determined that there was a coolant leak inside the engine. The contact was informed that the vehicle was covered under warranty and that an undisclosed part inside the coolant system was replaced. The contact stated that one week after the repair, the message returned, and the contact was informed that the upper coolant hose was defective. The contact was informed that the vehicle was no longer covered under warranty and the contact paid for the repair. After the second repair, the contact stated that the failure retuned and there was coolant leaking from the vehicle. The manufacturer was notified of the failure and referred the contact back to the dealer. The vehicle was not repaired. The failure mileage was approximately 64,000.
I have been smelling a vinegar smell in my vehicle for 1 week upon turning on the air conditioner. At the end of one week I have been having several health issues and I am concerned that this is mold, mildew, or another toxic chemical. I live in las vegas where temperatures have reached 3 digits and I am unable to use my air conditioner due to this horrible smell. I ended up in the hospital this week and no one knows what the issue could be. I am concerned that it’s from breathing in toxins from my car.
Engine suddenly lost most of power, causing risks of losing control. Diagnosis suggests a bug in digital motor electronics (dme) unit. Per TSB si b12 08 18, the correction is to update software. This should be a recall to make sure drivers don't experience sudden engine malfunction during driving.
