Mercedes-Benz Reviews 558

I’ve driven Mercedes Benz exclusively for 41 years. I purchased a new GLS 580 GLS on 6/30/2025, it was at the dealership multiple times and declared unrepairable so on 10/10/2025 I purchased a 2026 GLS 580 .
Upon delivery I had an issue with the transmission. I took it multiple times (4) to both dealerships in my area and was told every time that the transmission was acting as it should. Upon the 5th time taken in I was told that it needed a new gear box from Mercedes in Germany. After another week without my vehicle, I got a call from the dealership stating that when they drained the transmission fluid, they found metal chips and declared that the vehicle needed a full transmission replacement. I was without the vehicle for 12 days on this visit, and upon picking up my vehicle with in two blocks, the seatbelt alarm went off and would not stop.
Two days later it went back to the dealership where I was told that I needed a new seatbelt for the third seat. After waiting for the part several more days, I was called again by the dealership that it was not the seatbelt but rather a faulty wiring that came from the factory defective.
In addition to these issues, this 2026 vehicle has had the vehicle in twice for the same issue as the 2025 engine light and there is no repair available for this issue.
I reached out to the Huntsville Mercedes Benz dealership and kept them informed each and every time I tried to get this vehicle repaired.
This dealership is TOTALLY UNTRUSTWORTHY as I have purchased vehicles from multiple dealerships over the years and this experience with my salesman and general manager were hands down the absolute worst experience of my 41 years. I would NEVER RECOMMEND Mercedes Benz of Huntsville to any honest customer seeking honest dealings.
In addition Mercedes Benz Corporate has lied to me, delayed a response for a significant period and ultimately stated that they are not doing anything to resolve my issue!
41 years of dedication to a brand is completely disregarded in spite of the overwhelming facts that are prevalent.
The 2025 GLS 580 and the 2026 580 GLS are the 5th and 6th of this GLS that I have owned.
The 2025 and 2026 models are in no way a representation of a quality vehicle that I have ever owned previously.
Don’t walk, RUN from purchasing either of these models as they are unrepresentative of a high end vehicle.
Again I would reiterate the dissatisfaction with the general manager and salesman at the Huntsville dealership.

Overpriced, Overhyped, and Underwhelming, I was sold a faulty vehicle

Honestly, this Mercedes has been nothing but a disappointment. For a brand that constantly brags about luxury and engineering, the reality is shockingly poor. The interior looks flashy at first, but once you actually live with it, you start noticing cheap plastics, rattles, and questionable build quality everywhere. It feels more like a dressed-up economy car than a premium vehicle.

The technology is another headache. The infotainment system is slow, confusing, and clearly designed to look impressive rather than actually work well. Simple tasks become frustrating, and it’s honestly distracting while driving. Not what you’d expect from a so-called luxury brand. 🙄

Reliability has also been a joke. Multiple trips to the dealership for small issues shouldn’t happen on a car at this price point. Add in the ridiculously high service costs, and it just feels like you’re constantly paying for the badge rather than getting real value. 💸

There are far better cars out there for less money without the headaches.

Bottom line: All style, very little substance. Save your money and avoid the frustration. 🚫

I went on Thursday March 26 to test drive with Vince was great, he showed us the different cars, the sales rep was very knowledgeable, they answered all our questions.
We were approved on Monday and picked up the car on Tuesday afternoon.
Everything went smoothly! Wayne Hui the sales rep and Joslyn the Tech guy are both knowledgeable & helpful.

Terrible customer service, car is in at Mercedes lakeside for the past 3 weeks. Cant get hold of anyone there on the phone. Very rude staff.

This is the Story "I'm shocked to receive a £48 charge for early contract cancellation, especially after being a loyal customer for over 20 years. I cancelled the service plan as I'd fully paid off my Mercedes-Benz (£22,750) and downsized due to job loss.

I feel disappointed and humiliated by this unexpected demand. Given the circumstances, I request you reconsider this charge.

I will pay if needed, but this experience ensures I'll never purchase from Mercedes-Benz again and will share my experience with family and friends."

Mercedes,benz customer services very same as the garage i made the purchase of my cla250+ amg line disgraceful ie verification of my concerns issues with the vehicle on collection backed up by another mercedes garage written report verification of faults by Cadimar mercedes benz,jerez,and customer services mercedes obviously after collusion with fervial sevilla washed thier hands of my major issues and proven official report from the other mercedes garage jerez,I will never ever again deal with mercedes benz whose reputation is in the dirt as,far as I am concerned I have in the past dealt with bmw,audi,Honda in my opinion every bit more professional in dealing with issues,MB Cowboys thieves and fervial sevilla vaqueros thieves liars devious not honest in any way my rating is a big ZERO

I have been a Mercedes-Benz lover and owner of most models over the years. I worked for MB dealerships and for MBUK for several years until the early 2000's. My hubby and I currently own an SLK, as I have always loved these cars since the launch when I worked for MBUK. It recently failed its MOT due to a subframe corrosion/cracking issue that MB is aware of and has previously recalled and carried out repairs on several vehicles with this fault. They extended the warranty as a result of this fault. However, they are only now prepared to pay for half the cost of repair for our car, which is now 10 years old. This is still a bill for a considerable amount of money. They have admitted the manufacturing fault, and there is plenty of evidence online detailing this issue. I am just writing this as I feel totally let down by a brand I have been a true believer in for many years. When I worked for the brand, it was drilled into me that the customer is the most important person and that nothing beats a Mercedes-Benz for quality, reliabily and prestige. I feel those days are now diluted with poor customer service, disappointing build quality, and disrespect for MB owners. In my day, it didn't matter if a customer had a 20-year-old MB or a 20-minute-old MB; every customer was equal and treated with the utmost care and respect. Disappointing Mercedes-Benz! I can not believe I am now finding myself looking to other brands that, quite frankly, are knocking you off the top spot!

A third party drove into the back of my 2015 C Class requiring a replacement rear bumper. Other party insurance company put me in touch with their authorised repairer who ordered part through Mercedes franchise in Belfast. That was at start of Jan 26 and still waiting with no date for delivery. Contacted Mercedes UK and submitted a complaint and received a glib response stating car was not purchased by the Belfast franchise nor serviced by them and as such no entitlement to a loan vehicle. These 3 facts were introduced with no connection to the complaint, were never raised by me as a relevant issue and were thrown in to conflate the actual complaint issue. Car was bought at the franchises sister showroom, is serviced at a local Mercedes authorised garage and a loan car was never requested. The comment regarding the repairer is also irrelevant unless they would provide a bumper quicker if the franchise was conducting the repairs? They then went on to say I may get an update in May, not the bumper but an update. They also state that the car is 12 years old but don’t state what the relevance to this is as I was the one that told them the year of manufacture. They then finish by saying the part availability is outside of their control! Well then who’s control is it within? Who’s control should it be within? Let me think! Mercedes? Well it seems not in this case. Correspondence finishes by saying they are closing the complaint.

Absolutely awful first time experience buying a Mercedes. After all the initial trouble I had..see other review. I discovered Mercedes Benz Southend had sold me the car with a damaged washer reservoir. 3 months later, numerous emails and phone calls to MB HQ. And the Advocacy team in Holland( who you can't call and are Absolutely useless). The Advocacy team tell me," We can't reach a decision going forward. So you repair it and ring MB Southend to get compensated."
Why do you think I'm going through you to sort it out! Anyway I would advise anyone to buy elsewhere. If you want a Mercedes, fine. Just don't but from a MB garage. Go somewhere else. Or if you want my advice and want a german car. Buy an Audi, everything is cheaper. Servicing, parts etc.
And the garages aren't franchises like MB which I've now found out. Which Causes all kinds of problems with warranties going forward. What a nightmare.

Subject: Urgent Safety Concern Regarding Mercedes CLA 250+ EV – Case 21003121

For the attention of Jonathan Lipman, CEO

Good afternoon Jonathan,

I am writing to you directly because I have experienced an extremely serious and potentially life‑threatening issue with my new Mercedes CLA 250+ EV (85kW), and the response from Mercedes‑Benz UK so far has been deeply concerning.

I appreciate this may sound dramatic, but what occurred was nothing short of a near‑death experience. Please allow me to explain.

I have been a loyal Mercedes owner for many years, and my family also drive and enjoy Mercedes vehicles. Recently, due to my company moving to a salary‑sacrifice scheme, I leased the CLA 250+ EV through Tusker. The vehicle is just over a month old and has covered approximately 3,200 miles.

However, I have now experienced two extremely dangerous incidents, both occurring without any driver input from me:

Incident 1 – M11 Motorway
While travelling at approximately 65–70mph in the middle lane of the M11, the car suddenly:

Activated the hazard lights
Applied the brakes
Pulled sharply toward the hard shoulder
This manoeuvre would have driven me directly into HGVs travelling in the inside lane. The explanation given afterwards was that I “had not moved the steering wheel”. On a motorway, which is largely straight, this is hardly unusual.

Incident 2 – Full Emergency Stop
A few days later, on my commute, the vehicle performed a full emergency stop, bringing the car to a complete halt on an open road.
This happened again on my return journey, this time with a Ford Transit van behind me. How the driver avoided hitting me, I genuinely do not know.

In both cases, I was effectively a passenger in a vehicle making its own decisions.

Mercedes Cambridge Response
The car was recovered to Mercedes Cambridge, where diagnostics and a software update were carried out. When I collected the vehicle, I asked two simple questions:

What caused these incidents?
I was told diagnostics were completed and software updated, but no cause was identified.

Can you guarantee this will not happen again?
I was told no, there are no guarantees.

This leaves me driving a vehicle that could, at any moment, decide to brake or swerve without warning. I do not feel comfortable allowing my wife to drive it, which is clearly unacceptable.

Case Handling – Deeply Troubling
Case 21003121 was opened and then closed without any resolution or explanation. I had to chase this myself, only to be told the case had been closed.
Given the seriousness of what occurred, I find it astonishing that Mercedes would close a case involving:

A brand‑new vehicle
Multiple uncommanded emergency interventions
A clear risk to life
This is not only unsettling but suggests a worrying lack of urgency around a potentially systemic safety issue.

What I Am Requesting
I am asking for:

A full investigation into these incidents
A clear explanation of how a new Mercedes vehicle can behave in such a dangerous manner
Confirmation of what steps Mercedes will take to ensure this does not happen again
Clarification on why my case was closed without resolution
These advanced safety systems are designed to prevent accidents, not cause them. At present, I have no confidence in the safety of this vehicle, and I believe Mercedes should treat this matter with the seriousness it deserves

I wish I had read the reviews sooner.
Ive owned many used mercedes, but this time I decided to buy brand new and I expected a level of aftercare service to come with that. The service is appalling, worse than anything ive experienced. They call me and email me constantly to sell me products but not one phone call or email response regarding the fault on my BRAND NEW CAR. I need another new car also, but I wont be buying mercedes again.

I spoke to an agent tried multiple times to explain the issue . he could not understand. even getting the correct spelling of my name after repeating it over 5 times was a struggle. Then came the vin number . total time on phone was 45 minutes now. He said he will call me back in a day after checking with his superiors. Calls me 2 days later with absolutely no help. He was clueless of the automotive industry.after 30 minutes of wasted time he now tells me he cant find my vin number lol . i realized i was talking to a totally incompetent individual. Not sure how he even got the job. Is this the hiring standards benz sets for customer service lol what a joke. Before you decide to buy a Mercedes benz after watching an excellent crafted commercial on tv. Call their customer service.

After a service at Stevenage Mercedes, the engine light came on. I called the RAC who told me that the dealer didn't plug the EGR valve in correctly. I contacted the Service manager about this and he denied everything and said it wasn't them? Then on another service the technician damaged my antifreeze cap, it was over tightened and stuck, then it started to leak. That's the last time I went back, they can't even do a simple job. They also kept me waiting for ages and spent most of their time talking to each other than looking after their customers. I complained to head office, see if they get their act together! Very Poor!

Mercedes EQB - turned on and locked itself while I picked up kids from daycare. The key wouldn’t let me in. When I called customer service and explained I’m alone with 4 kids, they stated they couldn’t help as it wasn’t within their policy. The lady on the phone was extremely rude.

Fantastic service from Mercedes-Benz of Northampton. Keith Parrott
was brilliant - professional, friendly, and kept us informed throughout. He even sent a detailed video showing how good the car was, which gave us great confidence.
We didn't even have to take the car in ourselves as it was collected for us - truly above and beyond service. Highly recommend, and we'll definitely be back!

Big thank you to Sarah at Thurrock Van Centre...very polite and useful

Mercedes Benz Dealership Stevenage. I bought my car from them 10yrs ago and had service plan with them since it came out of warranty. The car used to be collected and dropped of, there customer service matched what you expect from a premium car brand. November 2025 car had a red engine diagnostics light come on as the car would not start, booked the car in for inspection. Never heard from them about collecting car so I had to call them at 5pm, and was told car was not ready as only went into workshop at 4pm and this type of diagnostic need time to look at it, this had massive impact on me having to re arrange things. Collected car following day later afternoon and they said nothing wrong with car, 2 months later same thing happened called the breakdown service, they came out and said it was the battery that needed replacing !!! Feb 2026 car booked in for service and mot, no longer collect and drop off. Called them at 4pm to see when can collect car and told won’t be ready as due to age and amg needed a new oil filter, this was a Friday night !! Made them give a courtesy car and spoke to the business manager about appalling customer service AGAIN. Monday call them at 2pm as not heard from them and they said car ready, get there get car asked if everything done including new windscreen wipers, told yes. Drive away starts raining turn wipers on and they had not been replaced, so have to drive back and was told no they had not been replaced. No one knows what they are doing, no planning in the workshop, no phone calls from service dept and the business manager who we complained to on Friday night just sat in his office on the Monday when I went back to say I have just had to drive back for wipers to be done..

I have a Sprinter Van and it is outstanding. On 50,000 miles and other than the usual throttle body issue (easy to diagnose and fix) no problems.
Dealers are very effective too.

Brand New Mercedes-Benz EQB 250+ Failed on Day One – No Support, No Courtesy Car, Salary Still Deducted

I ordered a brand-new Mercedes-Benz EQB 250+ in November 2025, delivered on 30 January 2026. On the very first day of driving, after approximately 70 miles, the fully charged battery (showing around 320 miles of range) completely drained without warning.

The vehicle became totally inoperable. I could not change gear, the doors locked, and a message appeared stating:
“Consult workshop without changing the transmission position.”

The car has been with the Mercedes dealer since the second day after delivery. Despite this:

Salary deductions have continued.

No courtesy vehicle has been provided.

Communication from both NHS Fleet and Athlon Mobility Lease Ltd has been poor and unsupportive.

There has been no urgency shown despite clear safety concerns.

I issued a formal 14-day notice to both parties requesting rejection of the vehicle. I received no meaningful response. After informing NHS Payroll about the ongoing salary deductions for a vehicle I cannot use, I then received what felt like a threatening letter from NHS Fleet customer service stating that I cannot reject the vehicle, even if faulty.

They stated that because the scheme is administered through my employer, it is considered an unregulated arrangement by the Financial Conduct Authority (FCA) and therefore does not fall under the Consumer Rights Act 2015 or FCA protections.

To summarise:

• A brand-new vehicle failed dangerously on day one.
• The fault has been verified and the vehicle has remained at the dealer since.
• I have had no courtesy car.
• My salary continues to be deducted.
• My formal notice has been dismissed.
• I have been told I have no consumer protection rights.

This experience has been deeply stressful and completely unacceptable. For a scheme designed to support NHS staff, the lack of accountability, empathy, and practical support is shocking.

I would strongly urge NHS Fleet and Athlon Mobility Lease Ltd to review both their safety procedures and their treatment of customers.
