BMW M340I recalls

13 recalls covering model years 2020, 2021, 2022. To check whether your vehicle is affected, look up your 17-character VIN at nhtsa.gov/recalls — a recall may apply only to some vehicles of a given year.

BMW X5, X6, X7 and sedans risk starter motor fire critical

Reported 2024-08-01 · Campaign 24V576000 · Model years: 2020

If the starter motor fails, repeatedly trying to start the engine can push too much electricity through it and make it overheat. A starter that gets that hot can set fire to nearby flammable parts in the engine compartment. The risk builds up when you keep cranking a car that will not start. A dealer will update the vehicle's software free of charge so the starter cannot be overloaded this way. BMW mailed owner letters on September 27, 2024.

BMW M340i and M440i seat belt warning chime may fail low

Reported 2023-08-16 · Campaign 23V584000 · Model years: 2020, 2021, 2022

The software in the radio and audio control unit may not sound the chime that reminds the driver to buckle up. Without that reminder, a driver could pull away unbelted and not notice. Federal safety rules require this warning, so these cars do not currently meet the standard. Nothing else about the car is affected, and the seat belts and airbags themselves still work normally. A dealer will reload the software on that unit.

BMW 3 Series, X3 and X4 seat frames poorly welded high

Reported 2023-03-29 · Campaign 23V211000 · Model years: 2020, 2021

The metal frame of a seat may not have been welded properly to the rails it sits on — the rails are what bolt the seat to the floor and let it slide. A badly welded frame may not hold a person in place in a crash, so you could be hurt more badly in a crash. Dealers will replace the seat frame and the seat back free of charge.

BMW and Toyota Supra lose power brake assist high

Reported 2021-08-02 · Campaign 21V598000 · Model years: 2020

In certain BMW cars and the Toyota Supra, a software error in the engine computer can cut off the power assist for your brakes when the engine starts. The brakes still work mechanically, but without the boost you're used to, so the pedal will feel much harder to push and you'll need to press far more firmly to slow down. BMW dealers will reprogram the engine software at no cost to you.

BMW, MINI, Toyota Supra passenger seat belt retractor fault medium

Reported 2021-07-21 · Campaign 21V554000 · Model years: 2021

The passenger seat belt has a locking mode that clamps the belt tight so it cannot loosen. On these cars that lock can switch off too early, before the belt has pulled all the way in. The belt then may not hold as it should in a crash, raising the chance of injury. The dealer will inspect the belts and retractors and replace them if needed, at no cost.

BMW 3 Series and M3 seat belt bolts loose high

Reported 2021-04-28 · Campaign 21V298000 · Model years: 2021

On these BMW 330i, 330e, M340i, and M3 cars, the bolt that holds a front seat belt to the body of the car was not tightened enough at the factory. A loose bolt means the seat belt may not hold you in place properly if you are in a crash. Nothing looks or feels wrong from the driver's seat, so you cannot spot this yourself, and an occupant could be injured more seriously in a collision.

BMW Cars and SUVs: Backup Camera Image May Fail medium

Reported 2021-02-19 · Campaign 21V096000 · Model years: 2020, 2021

When you shift into Reverse on these BMW cars and SUVs, the backup camera may not work properly. Part of the picture can be blocked, or the screen may stay dark and show no image at all. Backup cameras are required so you can see people, pets and objects directly behind the vehicle. If you rely only on the screen while backing up, you could hit something or someone you cannot see. A dealer will check the camera software and update it if needed, at no cost.

BMW 48-Volt Battery Connection May Overheat and Cause Fire critical

Reported 2020-12-09 · Campaign 20V761000 · Model years: 2021

These BMWs have a 48-volt battery that works with a starter-generator, a combined starter and charging unit. The connection between that battery and the starter-generator may not have been put together correctly at the factory. A poorly assembled connection resists the flow of electricity and can heat up, and that heat can lead to a fire. Your dealer will inspect the connection and replace it if it is not right, at no cost to you.

BMW and Toyota Supra steering tie rod can break high

Reported 2020-06-15 · Campaign 20V355000 · Model years: 2020

A tie rod is part of the linkage that turns the front wheels when you steer. On these cars, driving in hot weather or on rough roads can damage a tie rod, and a damaged one can crack all the way through. If that happens, the car may not steer or handle the way you expect, which could cause a crash. BMW and Toyota dealers replace the steering tie rods free of charge, and have been doing so since August 2020.

BMW X3, X4 and 3-Series seat belt sensor fault medium

Reported 2020-03-19 · Campaign 20V164000 · Model years: 2020

Sensors inside the front seat belt buckles may wrongly read a buckled-up person as unbuckled. The car uses that signal to decide how the front airbags and the seat belt tighteners should fire in a crash. With the wrong information, those safety devices may not go off the way they are supposed to. Dealers will inspect the driver and front passenger buckles and replace them if they find a problem.

BMW M340i trunk release may not open from inside medium

Reported 2019-10-23 · Campaign 19V755000 · Model years: 2020

Every new car sold in the U.S. must have a release inside the trunk so that anyone shut in there can push the lid open from the inside. On some of these BMW 3 Series cars, including the M340i, that release cable was not installed correctly at the factory, so pulling it may not open the trunk. Someone closed inside — most likely a child playing — might not be able to get out. A dealer will check the cable and install it properly.

BMW and Toyota Supra backup camera picture can vanish low

Reported 2019-09-27 · Campaign 19V684000 · Model years: 2020

On these BMW, Rolls-Royce and Toyota Supra vehicles, the camera and screen settings can be changed so the rear view picture no longer appears. The vehicle then remembers that setting, so the next time you shift into reverse the picture is still missing and you cannot see what is directly behind you. Federal rules require that image to appear, so these vehicles do not meet the standard. Dealers correct it with a free software update to the camera system.

BMW M340i rear center headrest may fold in crash medium

Reported 2019-08-14 · Campaign 19V600000 · Model years: 2020

Only two of these cars are affected by this recall. The headrest in the middle of the back seat was not welded together properly when it was built. Because of that bad weld, it can fold forward if the car is hit from behind. A headrest is meant to stay upright and support a passenger's head and neck in a rear-end crash, so someone riding in the middle of the back seat could be hurt worse. Dealers will replace it.
