Owning a BMW i8, especially a used one, can present a range of issues due to the car's complex hybrid technology and luxury features. Here’s a rundown of common problems you might encounter with a BMW i8, particularly a cheaper, older model:
Common Issues with the BMW i8
Battery and Electrical Problems:
High-Voltage Battery Degradation: The i8's high-voltage battery can degrade over time, leading to reduced electric range and performance. Replacing this battery can be extremely costly.
12V Battery Issues: The auxiliary 12V battery is known to fail, causing various electrical problems and potentially leaving the car unable to start.
Charging Problems: Some owners report issues with the car not charging properly, whether at home or at public stations.
Engine and Hybrid System:
Engine Mounts: The i8's engine mounts can wear out prematurely, leading to increased vibrations and noise.
Hybrid System Errors: Faults in the hybrid system can trigger warning lights and affect the car's performance. Diagnosing and fixing these issues often requires specialized knowledge and equipment.
Turbocharger Issues: Problems with the turbocharger, such as leaks or failures, can occur, especially in older models with high mileage.
Transmission and Drivetrain:
Transmission Faults: Issues with the transmission, including rough shifting and slipping, have been reported by some owners.
Drivetrain Noise: Unusual noises from the drivetrain, such as whining or clunking, can indicate wear and tear or more serious issues.
Suspension and Steering:
Suspension Wear: Components like the control arms, bushings, and struts can wear out, leading to poor handling and increased road noise.
Steering Rack Problems: Some i8s have experienced issues with the steering rack, resulting in a lack of responsiveness or unusual noises when turning.

Interior and Comfort:
Electronic Glitches: The i8's sophisticated electronics, including the infotainment system and digital displays, can be prone to glitches and failures.
Climate Control Issues: Problems with the climate control system, such as failing air conditioning compressors or heater malfunctions, have been noted.
Seat Comfort: The sporty seats, while supportive, can become uncomfortable on longer journeys, and some users report issues with the seat adjustment mechanisms.
Body and Exterior:
Door Mechanisms: The i8's scissor doors, while stylish, can develop issues with the hinges and latches, leading to difficulties in opening and closing them.
Water Leaks: Some owners have reported water ingress issues, particularly around the door seals and windows, which can lead to interior damage.
Specific Owner Experiences
Reliability Concerns: Many owners of older BMW i8s have reported reliability issues that arise from the car’s complex hybrid system and high-tech features. Regular maintenance and timely repairs are crucial to keep the car running smoothly.
Cost of Repairs: Due to its exotic nature and advanced technology, repair costs for the BMW i8 can be significantly higher than for more conventional vehicles. Parts availability and the need for specialized labor further drive up costs.
Summary
While the BMW i8 is an impressive and innovative sports car, owning a cheaper, older model comes with its share of challenges. Potential buyers should be aware of the high maintenance and repair costs associated with the vehicle, as well as the common issues outlined above. Proper maintenance and purchasing from a reputable seller with a comprehensive service history can help mitigate some of these problems. Ev BMW Database.
