2017 BMW 330I Unknown Or Other Problems

2 low coolant warnings within 4 months ended up being an oil filter housing failure, leading to oil and coolant mixing and leaking. This failure could have lead to catastrophic engine damage. An ASE certified shop is doing the repair for around $2,950.

In October of 2023. I notice low coolant notification came on screen. checked coolant saw it was low. Added Coolants. 3 days later same notification. Took vehicle to Shop who stated the coolant cap seal was broken, so I had them replace the coolant cap. 3 days later the same Low coolant light came back. Every few days I had to put coolant in my vehicle. I went through 2 bottles of coolant. Over the Christmas holiday Dec/2023. I dropped my vehicle off at a shop. The oil filter housing and cooler gaskets was bad. BMW replaced this piece from a metal part with a plastic piece. This is my only vehicle and I had to pay for this expensive repair so I could get back and forth to work. Prior to me having the repair done, when I was trying to figure out the problem. I noticed a lot of online information of the same issues for 2017 BMW 330I. THe shop . did the repair told me he had done about 10 of these repairs for the same Year/Make and Model.,the past few months. I had to pay $2,637.20 for this repair. There is clearly a notable problem with coolant leaks. I make sure I have vehicle serviced when the notifications come on the screen and have documentation to show this. Please look into this issues.

out of nowhere with only 1 day warning car requested coolant refill. After refill within 10 minutes car engine ran hot and completely stopped on the expressway. I’ve read hundreds of reviews online and youtube where this exact same thing has happened to others with this same car.

I received a warning on the dashboard that the tires needed inflating and that I should not drive the car over 80 miles per hour. When this happened the communication system on the car failed. I could not use the telephone or the direction feature. I do not know if other parts of the car also failed. When the tires were re inflated, these other features returned. This has happened twice. (In addition the tires needed reinflating on one or two other times.) BMW offers a courtesy service to reinflate the tires so that they don't maintain a record of the problem and they are unable to add a note to their service record to document the problem.

IN MARCH 2022 I WAS DRIVING HOME FROM WORK AND I NOTICED SMOKE COMING FROM UNDER MY HOOD. I WAS ABLE TO MAKE IT TO A MECHANICAL SHOP CLOSE BY. I WAS INFORMED THAT QUICK RELEASE COUPLING OF THE VENTILATION LINE O FTHE CYLINDER HEAD HAD TO BE REPLACED. BMW PART # 17129845173. AS A RESULT OF THIS MALFUNCTION ALL OF THE COOLANT DRAINED FROM THE CAR WHICH CAUSED THE OVERHEATING. IN AUGUST OF 2022 I RECEIVED A LETTER FROM BMW USA THAT STATED "DURING A RECENT QUALITY ANALYSIS IT HAS BEEN DETERMINED THAT THE QUICK RELEASE COUPLING OF THE VENTILATION LINE O FTHE CYLINDER HEAD COULD BREAK RESULTING IN COOLANT LOSS. THE LETTER SAID U SHOLD BRING IT TO MY LOCAL BMW DEALERSHIP TO BE REPLACED FREE OF CHARGE. I BROUGHT IT TO THE DEALER AND THEY REPLACED IT WITH BMW PART # 17129845173 (SAME EXACT PART NUMBER). I ASKED IF I COULD BE REIMBURSED SINCE THIS IS WHAT HAPPENED TO MY CAR. THE SALES ASSOCIATE SAID I HAVE TO GO THOROUGH BMW AMERICA WHO SAID, YES THIS IS THE EXACT SAME PART AND THE CURRENT PROBLEM IS WHAT HAPPENED TO YOU IN MARCH BUT THEY WOULD NOT REIMBURSE ME FOR THE ALMOST 800.00 I PAID TO GET IT FIXED BEFORE I RECEIVED THE RECALL LETTER. THE BMW REPRESENTATIVE THEN PROCEED TO TELL ME " ma’am, let me remind you that you drive a luxury vehicle so next time you have a problem I would suggest pulling over on the side of the road and towing it to a dealer”. I Informed this representative that I was thinking of my safety. I am a single female, in the dark, with my car smoking on the highway and my first instinct was not to pull over on the side of the highway, wait for a tow truck, then find my own ride home from a far away BMW dealership. I HAVE ALL DOCUMENTATION THAT INCLUDES THE INITIAL WORK, THE RECALL LETTER FROM BMW AND THE WORK DONE AT THE BMW DEALERSHIP SHOWING THAT IT WAS THE EXACT SAME PROBLEM. I AM SEEKING REIMBURSEMENT OF THE ORIGINAL WORK AS THIS WAS A KNOWN PROBLEM AND WAS ALERTED BY BMW INDICATING THAT THIS COULD HAPPEN TO VEHICLE AND NEEDD TO BE FIXED.

When I was driving on suburban roads with speed limit of 45 mph, I received a waring from my vehicle saying "engine high temperature, drive moderately". After sometime, it said "engine overheated stop carefully". During the first warning, I felt loss of acceleration power and during the second warning I felt completely no power in acceleration that too when I was yielding for a left turn which was life threatening, luckily the oncoming traffic slowed down. Otherwise I would have ended up in life threatening crash. During both warnings, I checked the engine temperature gauge in the instrument cluster and the engine temperature was not even 50% of the maximum temperature in the gauge. After the warning, I slowly made it to a nearby parking lot and opened the hood and did not physically feel any excessive heat for an engine not to function. I regularly service my vehicle and my vehicle is not due for any kind of service for the next 2000 mile as per the onboard vehicle status. The next day I started the vehicle to help it to climb the tow truck ramp and at that time, for the very first time I received a warning saying engine coolant is very low. I have never received this warning since I have owned the car until then. I have two concerns, 1. The temperature gauge did not show a high temperature, only 24 hours after the electronic engine high heat notification, the low coolant warning came in which is weird and my vehicle isn't due for any service. 2. None of the above should result in a sudden loss of acceleration power which could have resulted in a fatal crash in my case. I'm a mechanical engineer with a strong background in automotive occupant safety (airbags/seatbelts) and that's why I see this a very serious incident that needs to be looked into so that it doesn't occur for anyone else in the future.

We had a 2017 bmw 330i x-drive. It had approximately 67000 miles. The car stalled while driving about 6 times. The first time was in 3/2021. The diagnostics were for a faulty high pressure fuel pump. We replaced the HPFP. It stalled again while driving. The diagnostics were for a faulty low pressure fuel pump. We replaced this. The car then stalled while driving 2 more times. The car stalled again in 10/2021, and we towed it to the dealer, who diagnosed a problem with the electric fuel pump control unit., which the dealer replaced. We brought the car home for one day, and we had the same problem again. We brought the car back to the BMW dealer, who diagnosed a problem with the VANOS system. The BMW Peabody dealer directed us to BMW corporate for evaluation of available warranties and rebates given the nature of the problem (VANOS) being warranted under the California SULEV emissions standards and the fact that they dealer had diagnosed a separate problem the day before. We sent the diagnostics and the SULEV warranty info to Sean, as everyone at BMW seemed unaware of its existence and who was responsible for following it. He took weeks “looking into it,” and the dealer repaired the VANOS during this time without a final answer from corporate. A car stopping while driving is clearly dangerous to the occupants and surrounding vehicles. BMW did not honor the SULEV warranty, which clearly covers the VANOS and the fuel pumps until 70000 miles. The car was traded to BMW Peabody, as we no longer felt safe driving it. We do not know if the replacement of the VANOS fixed the problem.

Damaged heat exchanger from debris/rocks getting through grill of car. Now A/C SYSTEM IS BLOWING WARM AIR, IT WILL BLOW COOL FOR A VERY SHORT PERIOD AND THEN GET VERY HOT and car overheats. BMW dealer says the radiator needs replaced and will cost $1600. BMWs after 2017 are now manufactured with a mesh grill covering/rock guard to prevent these issues. This should be covered under my warranty and is not.

DRIVING ON THE HIGHWAY AT APPROXIMATELY 60 MPH. SUNROOF AND SHADE WERE BOTH CLOSED. I WAS ACCELERATING SLOWLY. HEARD A SUDDEN, VERY LOUD POP AND GLASS BEGAN TO ENTER THROUGH THE SHADE VENTING AREA. A LARGE PORTION OF GLASS (PROBABLY 1/3 - 1/2) DISLODGED FROM THE AREA, SCRAPED THE BACK OF THE CAR AND LAUNCHED ONTO THE HIGHWAY BEHIND ME. THIS COULD HAVE EASILY CAUSED A MAJOR ACCIDENT FOR MYSELF AND OTHERS BEHIND ME, MUCH LIKE ICE WOULD IF RELEASED FROM THE HOOD OF A MOVING CA.. I WAS ABLE TO PULL OVER AND EVALUATE THE DAMAGE. THE SUNROOF APPEARED TO HAVE BUCKLED AND BLOWN OUT, AS THE SHARDS OF GLASS WERE POINTED OUTWARD FROM THE CAR. DEALERSHIP CLAIMS IT IS AN INSURANCE CLAIM AND NOT UNDER WARRANTY, DESPITE HAVING PURCHASED THE CAR CPO JUST OVER ONE MONTH AGO.

I WAS DRIVING ON A FREE WAY DURING RUSH HOUR WHEN I HEARD AN EXPLOSION. I PULLED OVER AND DISCOVERED THE MOON ROOF TO THE CAR HAD SHATTERED AND CREATED A VERTICAL PROTRUSION FROM THE WINDOW. THE TEMPERATURE THAT AFTERNOON WAS 109 AND I HAD DRIVEN FROM AN ALTITUDE OF 7,000 FEET TO 1,200 FEET. THERE WAS ALSO A SIGNIFICANT DROP IN TEMPERATURE FROM THE HIGHER ELEVATION. A HIGHWAY PATROL OFFICER STOPPED TO OFFER ASSISTANCE AND NOTED HE HAD WORKED IN DEALERSHIP AND THE PROBLEM WAS COMMON. AFTER HAVING THE CAR TOWED TO THE DEALERSHIP WHERE I HAD PURCHASED IT LESS THAN A WEEK EARLIER, THE SERVICE REPRESENTATIVE SAID A ROCK HAD HIT THE CAR AND I SHOULD CONTACT MY INSURANCE COMPANY. THE SERVICE REP INFORMED ME IT WAS IT WAS NOT A WARRANTY ISSUE WITHOUT EXAMINING THE CAR. I SHARED WHAT THE DPS OFFICER SAID AND THE SERVICE REP JUST SHOOK HIS HEAD. THE CAR IS A PREOWNED CERTIFIED VEHICLE.
