2018 Bmw 3 SERIES PHEV - Ratings, Complaints and Recalls

"at around 65k miles multiple plastic engine coolant connectors and hoses crack and fail. 5 locations at the same time! coolant pump leaks. i went to an independent repair shop for a second opinion and repairs for $2,400 so far. cheaper than the bmw service department. there was a recall done 2 years ago for 1 hose i believe. the entire cooling system should be recalled. we could be stranded somewhere in a bad situation and the engine could be destroyed if overheated. awful and bad design."

"my oil filter housing failed at about 53,000 miles. while driving to work i got a low coolant warning and pulled over to see coolant dumping out of my car. the low coolant warning only comes on when the expansion tank is almost completely empty which can lead to oil and coolant mixing and overheating which will lead to premature engine damage without any early warning signs. i’ve read through forums and everyone on there has their oil filter housing fail at the same time, (around 50-60k miles). this is a huge issue in the community and bmw wants to charge almost 3,500 to replace it with their “revised part”. the housing has been revised 3 times now and so the manufacturer should replace these failed designs with the new revised ones. there’s already been a recall on the b48 engine for the plastic cooling line that leads into the head of the engine and it looks like the oil filter housing is the next biggest common failure. i tried to upload a screenshot from the service center at bmw with the quote and failure but it’s not working on my mobile."

"the radiator failed due to rocks flying through the grill and smashing the radiator causing coolant to flow out of the radiator which could cause deadly issues if a car has no coolant while operating. bmw knows this is an issue and refuses to warranty/recall the parts. they know its an issue because after 12/17 every 340i came with a rock guard to protect the radiator but every car before that was just left to be victim of a potentially deadly situation including mine (manufactured 10/17). bmw refuses to acknowledge the problem but the addition of the rock guard to cars after 12/17 should be enough evidence to show they knew it was an issue. now all 2016-2018 m sport f30 chassis built before 12/7 are susceptible to this deadly situation and bmw refuses to cover for any damages even though they know it's a serious issue and they won't even cover the rock guard"

"unknown - i returned from a work related trip out of the country, started my vehicle and coolant was pouring everywhere. bmw stated there's a recall coming out but have not seen one since the repair in april which was over a thousand usd."

"on the way home from purchasing this vehicle as a cpo at the bmw dealer, a loud engine knock developed. made an appointment at the bmw dealer to check it, and on the way there, it lost power & engine malfunction warning lights illuminated. had to pull off highway, fearing car would stop running altogether. diagnosis was failed rod bearings, with lots of metal shavings in the oil filter. mileage was 36,500 miles."

"returning from a local grocery store i drove into our garage and shut off the engine. immediately i heard a loud pop from the engine compartment, like from a firecracker, and i saw black smoke coming from the hood and from the left wheel well. i immediately tried to restart the car to drive out of the garage. nothing worked so i pushed the car out of the garage by hand and released the hood latch. by now the hood's external safety latch was so hot i could not release it. with the hood closed, i was unable to extinguish the engine fire using a 15 lb co2 and a 5 lb abc extinguisher. the city fire department also were unable to extinguish the fire until they sawed the hood in half. the 2 1/2 year old car was a total loss. a expert from bmw of north america inspected the car reporting that was too much damage to determine the fire's cause. bmw na called to report the result not their investigation and say that no written report was available, only the verbal verbal fonecon."
