The fully electric BMW i4 Gran Coupe was launched in the U.S. in 2022 to much applause and highly complimentary media reviews. The 2023 model has followed in its footsteps with only very minor changes and reportedly no waning of interest. But the first model already has five recalls and the second, three. Complaints are also mounting up. 2023 owners are reporting unintended acceleration problems, issues with the cell monitoring circuit module, and CarPlay malfunctions that give the i4 erroneous navigation instructions that increase the risk of an accident.

Most Common Problems with the 2023 BMW i4
The most common problem 2023 BMW i4 owners are reporting to the National Highway Traffic Administration (NHTSA) relates to the wireless Apple CarPlay app. The problem is that it affects location and navigation information, which can be dangerous. There is one complaint about a faulty cell monitoring circuit module, which is serious. Unintended acceleration is also a reported problem.
The only components and systems that owners of the 2023 BMW i4 Gran Coupe name are vehicle speed control and the electrical system. All the CarPlay complaints are listed as unknown or other problems.
And then there are the recalls.
2023 BMW i4 Recalls
There are already 3 recalls for the 2023 BMW i4. Of these, 2 increase the risk of injury and the other increases the risk of a crash. These are also in place for the 2022 model that has 5 recalls. One that doesn’t apply to the 2023 model relates to the high voltage battery. It is an urgent recall that relates to a fire risk and warns owners not to drive the vehicle until the battery has been replaced. The other relates to the central information display that may not display warning messages and/or warning lights that contain critical safety information.
NHTSA Campaign Number 22V944000 involves the recall of 14,086 BMWs, some of which are 2023 i4 eDrive35, eDrive40, and i4 M50s.
The problem is that the high voltage battery electronic control unit (ECU) software may cause an interruption of electrical power. If this happens, the risk of a crash increases.
NHTSA Campaign Number 23V118000 affects only 120 vehicles including i4 eDrive40 and i4 M50s. The problem here is that if there was a service visit, a replacement electronic control unit may have been installed with incorrect programming. The warning is that this can cause the automatic door locking function to fail to lock the doors as intended. This can result in the doors opening if the i4 crashes, which increases the risk of injury.
The third recall affects 3,431 BMWs including 2023 i4 eDrive40s. During vehicle start-up, the artificial sound generator control unit may experience a fault and it won’t generate the external pedestrian warning sound. If pedestrians aren’t aware of approaching vehicles, they could get hurt. The NHTSA maintains that these vehicles don’t comply with the requirements of Federal Motor Vehicle Safety Standard number 141, Minimum Sound Requirements for Hybrid and Electric Vehicles.
Apple CarPlay Problems
Since this is the most complained about problem, let’s look at it first.
The problem, as all complainants state, is that “the on-board GPS sends incorrect information to Apple CarPlay devices, including both location and dead reckoning. This means that any application on the phone, including SOS and 911 calls, sends inaccurate location information when this is occurring. It is intermittent but acknowledged by BMW as an issue.”
He also points out that even though the CarPlay specifications point to Apple, “all GNSS information comes from the car to the phone,” so “this is 100% a BMW issue.” According to this complaint, this also happens with Android Auto. “There are also reports of this impacting the location BMW thinks the car has, including the My BMW app, which may also impact BMW’s emergency services.”
An owner from Washington adds that when the navigation keeps rerouting, this can be distracting to drivers. “It can also disorient the driver if they are driving in an area which is not familiar to them.”
What Happens if You Get the Wrong Data
An owner from California has thought this one through. “In some situations, the car sends the wrong GPS data to CarPlay, and then all the mapping applications in CarPlay (and on your phone) have the wrong location. When this happens, the car is shown way off course, and the navigation app starts giving you rerouting instructions to get you back on course. Of course, these instructions are nonsensical and the locations are sometimes comical — we live near a body of water, and the car is often shown driving through the water. This can only be corrected by rebooting the car’s iDrive system or by disconnecting your phone completely from the car.”
If you get the wrong navigation instructions, these can confuse you and potentially lead to an accident.
“But more importantly, the car is giving your phone the incorrect geo-location. This means that when you look at any map on your phone it shows you are in the wrong location.” He points out that all modern iPhones have an SOS feature.
“If your car crashes, it will call 911 and relay your location. However, it will send the ‘wrong’ location because it only knows what the car is telling it. This problem has been seen in several different BMW models; most often with cars that have iDrive 8. Based on BMW owner community forums, BMW dealers were made aware of the problem as long ago as June 2022. BMW USA has acknowledged the problem, and if pressed will say ‘we are working on a resolution’ but refuse to give a timeframe for a fix. In the meantime, they say ‘don’t use CarPlay maps’. But of course that doesn’t address the phone GPS / SOS issue.”
There is no doubt that this is a big worry for 2023 BMW i4 owners.
Faulty Cell Monitoring Circuit Module
The i4’s high-voltage battery consists of four modules with 72 cells each, and three 12-cell modules. But when it doesn’t work, the owner has a problem. An owner from Georgia complained to the NHTSA because the 2023 BMW i4 wouldn’t start.
He states that the message on the dash read “stop auto train failure contact roadside assistance.” He did what he thought was the right thing and called his car salesman first. The salesman “told me I had to contact roadside assistance myself.” but roadside assistance wasn’t able to diagnose or correct the problem and they called a tow truck. The car was towed to a dealership that day and “has been on the lot ever since. After many consultations with the BMW people in Germany, the analysis was that the cell monitoring circuit module needed to be replaced and the replacement part is scheduled to arrive mid-march, 2023.”
Unintended Acceleration Problems
Complaining to the NHTSA under Vehicle Speed Control problems, an owner from California states that while turning into a parking space, “the vehicle experienced sudden unintended acceleration and crashed into a post and then into a wall. No warning lights were illuminated.“ Fortunately nobody was hurt in the crash. The contact stated that there were no injuries sustained. A police report was not filed. The failure mileage was 2,098 and the owner hadn’t had the i4 checked out by the local dealer or a local dealer at the time of the complaint.
What if your 2023 BMW i4 is a Lemon?
Could your BMW i4 be lemon? If it is, chances are you’ve had recurring problems that affect the use of your super-new electric vehicle. It is probably also affecting its resale value. If so, it means that you may have bought a lemon. But you don’t have to live with it.
