Despite maintaining the vehicle according to the recommended schedule, I have encountered ongoing performance issues (electrical, rear shocks, fan motor etc.) that are not in line with the standard of quality I expect from a brand of your reputation. Window not going down all the way on the driver side. Radio not working but was fixed. These issues have caused inconvenience and concern regarding the reliability of the vehicle. To address my concerns, I spoke with a Mercedes-Benz representative who informed me that, due to the problems I’ve experienced, I may be eligible for either an extended warranty or a credit toward the purchase of a new vehicle. After careful consideration, I opted for the extended warranty. However, I was later informed that this option had not been approved—despite it initially being presented as available. This contradiction is both confusing and frustrating, and it has significantly diminished my confidence in the customer service process.

According to a MB USA representative, the warning light instructing me not to drive over 50 miles per hour was related to my suspension. In addition to the warning light, I have repeatedly expressed my concerns about a loud creaking noise coming from the wheel area while driving, turning the corner, pulling in and out of driveway, etc. However, South Bay Mercedes is never able to duplicate the noise or identity the warning. I have also contacted MB USA on multiple occasions and they confirmed that I have three (3) open cases, but refuse to provide me with the case number and fail to respond as stated during each call. The suspension warning light has been coming on, intermittently, a few months after I purchased the vehicle and South Bay Mercedes only suggested a tire change and service appointments while blatantly disregarding the problem. Now I am getting a warning light that states, Service Required Do Not Shift Gears Visit Dealer. I have had this car less than a year as it was purchased brand new, and South Bay Mercedes/MB USA have been giving me the runaround for months; only corresponding to schedule upcoming service appointments. I have since changed my front tires, but continue to get warning messages. I have repeatedly expressed concerns about my safety and never received a response from MB USA.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2022 Mercedes-benz GLB verdict →
