Engine

2.0L Turbocharged Inline-4 (B48)

• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher than expected oil consumption, requiring more frequent top-ups between oil changes. Symptoms include the “Check Engine Oil” light illuminating, a noticeable decrease in oil level on the dipstick, and potentially blue smoke from the exhaust.
  • Solution: Regular oil level checks and timely top-ups are recommended. If consumption is excessive (more than 1 quart per 1,000 miles), a dealer inspection is necessary to determine the cause. It could be related to valve stem seals or piston rings.
  • Estimated Cost to Fix: Inspection is usually free, but the repairs could be expensive if it requires a full engine rebuild ($3,000-$8,000+ depending on the shop).
  • Recalls: None Found

Transmission

8-Speed Automatic (Aisin)

• Rough Shifting/Hesitation
  • Description/Symptoms: Some owners have reported occasional rough shifts, particularly when cold or during certain driving conditions. There may also be a noticeable hesitation or delay when shifting between gears.
  • Solution: A software update of the transmission control module (TCM) can sometimes resolve these issues. In more severe cases, a valve body replacement or transmission rebuild may be necessary.
  • Estimated Cost to Fix: Software update ($100-$300), valve body replacement ($1,500-$3,000+), transmission rebuild ($4,000-$8,000+).
  • Recalls: None Found

Suspension

• Harsh Ride Quality
  • Description/Symptoms: The M235i’s suspension, while designed for sporty handling, can be perceived as harsh, especially on rough roads. This is often mentioned as a downside in reviews and owner forums.
  • Solution: There is no definitive fix for this, as it is a characteristic of the car’s suspension design. Some owners have experimented with aftermarket springs or dampers to improve ride comfort.
  • Estimated Cost to Fix: Aftermarket springs/dampers ($500 - $2,000+ plus installation).
  • Recalls: None Found

Electrical

• Infotainment System Glitches
  • Description/Symptoms: Some owners have reported occasional glitches with the iDrive infotainment system, including screen freezes, unresponsive controls, and Bluetooth connectivity issues.
  • Solution: Restarting the iDrive system (usually by holding down the volume knob) can often resolve temporary glitches. Software updates are also periodically released to address bugs.
  • Estimated Cost to Fix: Software updates are usually covered under warranty or can be performed by a dealer for a small fee (around $100-$200).
  • Recalls: None Found
• Malfunctioning Sensors
  • Description/Symptoms: Some owners have reported issues with sensors such as the tire pressure monitoring system (TPMS) sensors, parking sensors, or the adaptive cruise control sensors. This can result in warning lights, inaccurate readings, or system malfunctions.
  • Solution: Diagnostic testing is required to identify the faulty sensor. Replacement is typically necessary.
  • Estimated Cost to Fix: TPMS sensor replacement ($100-$300 per sensor), parking sensor replacement ($200-$500 per sensor), adaptive cruise control sensor ($500-$1,500+).
