Mercedes Panoramic Sunroof Problems

Mercedes Benz recalled approximately 750,000 vehicles from 2001 through 2011 due to defective sunroof glass that could suddenly detach. According to the recall notice, the bonding between the sunroof glass panel was too weak to hold it in place.

The sliding roof frame on specific Mercedes Benz models doesn’t meet quality specifications and can come out easily. If the glass panel separates, it causes a risk of injury or death to occupants or others on the road.

If your Mercedes Benz has sunroof problems and is not on the list for a recall and free repair, you could be in for a rough ride. Typically, manufacturer defects re-occur frequently and require expensive parts that are difficult to find.

California lemon laws are designed to protect consumers who buy a problematic vehicle—known as lemons. A California lemon law attorney can determine whether you are eligible and help you pursue compensation from the manufacturer.

Registered NHTSA Complaints

2007 Mercedes-Benz E-Class NHTSA ID: 11310144

The affected consumer owned a Mercedes-Benz 350, with the incident occurring in 2019. While seated, the driver pressed the sunroof button to open the glass panel, but instead, the glass panel collapsed inwards.

The driver took the vehicle to a Mercedes-Benz dealer in Mississippi, where it was diagnosed and repaired. The vehicle developed the sunroof problem after clocking a mileage of 31,941.

2009 Mercedes-Benz E-Class Wagon NHTSA ID 11326021

The affected owner noted an abnormal sound that was coming from the sunroof. In addition, the sunroof glass panel allowed air into the vehicle despite being closed. Upon contacting the authorized, the dealer informed the complainant that the replacement part for the recall repair was unavailable.

The car developed sunroof problems at 150,000 miles in May 2019.

2007 Mercedes-Benz C-Class 4DR RWD/AWD NHTSA ID: 11439016

The contact was driving at 60 mph when the sunroof exploded and became partially open. At first, it rattled and then shook violently before exploding.

The incident occurred in November 2021, after the July 2020 recall. With that in mind,  the consumer felt the manufacturer should have included the model in the recall list. Upon reporting to the dealer, the consumer was informed that the recall couldn’t apply because it was an explosion.

2005 Mercedes- Benz C-Class NHTSA ID: 11434051

The affected owner reported that water entered through the sunroof and damaged the car computer. After taking the car to an authorized dealer for repair, they were denied service.

Moreover, the manufacturer had exceeded the reasonable time for repair recall. 

2008 Mercedes-Benz E-Class 550 NHTSA ID 11387190

The incident occurred in January 2021 in Bethany, CT. While driving at regular speed, the sunroof detached without notice. Although the dealer repaired the damaged sunroof, the complainant was charged— despite being covered by VIN.

In addition, the manufacturer exceeded the reasonable time for repair recall.

2008 Mercedes-Benz CLK Class NHTSA ID 11325411

While driving at regular speeds, the affected driver heard a strange rattling from the sunroof before it came off. After reporting the issue to the dealer, the complainant didn’t receive help because the recall repair wasn’t available.

The sunroof failed when the vehicle had clocked 40,000 miles. Interestingly, the manufacturer advised the contact to avoid driving the vehicle before the dealer completed the repair.

Recalled Mercedes-Benz Vehicles

At least 79 Mercedes-Benz models are affected by the sunroof recall. These models include C-Class, wagons, CLS-Class, E-Class sedans, coupes, and CLK-Class.

Examples of affected vehicles include:

  • Mercedes-Benz C280 2006-2007
  • Mercedes-Benz C55  2005-2006
  • Mercedes-Benz CLS550 2007-2011
  • Mercedes-Benz CLK500 2003-2006
  • Mercedes-Benz E350 2006-2009

A point to note: Mercedes-Benz models C-Class, CLS-Class, E-class, and CLK Class manufactured in 1999 to 2010 are not on the recall list. Even so, they may be subjected to a recall if their sunroofs have been repaired between 2001 and 2011.

Description

The movable glass panel(sunroof) may separate from the vehicle and become a road hazard. According to the recall report, the vehicles with the defective sunroof were installed with a sliding roof frame that easily deteriorated and came out.

Remedy

The recall commenced in July 2020. Mercedes-Benz USA, LLC is obliged to notify the affected owners. On the other hand, authorized dealers will inspect glass bonding and replace the sunroof— if necessary— free of charge.

Common Hazards of Having a Defective Sunroof

Easy Access By Intruders

Generally, a sunroof increases the risk of your car being broken as the upper glass panel provides quick access. Therefore, a defective sunroof that’s shuttered or weak increases the risk of a break-in.

Causes Water Leakage

A defective sunroof accelerates water leakage into your car. The common causes include worn-out seal rubbers or clogged drain tubes. A functional drain tube is vital in directing water away from the sunroof. 

The water may leak into the cabin if it becomes clogged with dirt or debris. Unfortunately, water leakage may cause extensive damage to the car’s electrical or computer system.

Damages Car Interiors

When your sunroof comes off, it causes the car to heat up, initiating significant damage to your cabin. Unfortunately,  high temperatures degrade the appearance and durability of leather or plastic seats.

Protection of New and Used Mercedes Buyers Under Lemon Laws

Under California lemon laws, if a manufacturer or a dealer doesn’t repair a serious warranty defect after a ‘’reasonable’’ number of attempts, they must either:

  • Replace the vehicle
  • Refund its purchase price 

California Lemon Law Presumption

A dealer or manufacturer must refund or compensate for a defect or condition that significantly impairs the vehicle’s value, use, and safety. More importantly, the law of presumption applies if the dealer doesn’t find a solution.

The California Lemon law of presumption uses the following guidelines to determine whether a manufacturer or dealer has fulfilled a ‘’reasonable’’ number of repair attempts:

  • The manufacturer or dealer hasn’t fixed the problem after four or more attempts
  • The defect could cause death or bodily injury, and the dealer or manufacturer has made two unsuccessful repair attempts
  • The vehicle has been in the repair shop for more than 30 days, not necessarily in a row, for defects covered by the warranty.

Consult an Experienced California Lemon Law Attorney

Despite spending top dollar to acquire a luxury Mercedes-Benz, it can turn problematic. In addition to the risk of the sunroof glass panel coming off, you might regularly incur additional expenses like car rental charges when the car is in the repair shop.

It’s, therefore, essential to partner with an experienced lemon law attorney from LemonLaw123 to pursue a replacement or refund.

    "Pleased with the Service"

    Happy to hear from you. I was very pleased with the service you provided. I couldn’t be happier. The timing was excellent. I retired June 1st and didn’t really need the car anymore. I didn’t go out and buy another car. I decided to hang on to my money for a while.

    "Beyond Satisfied"

    I am beyond satisfied. After being told that I did not have a case by other attorneys, I was referred to Ms. Campbell and I am so glad I called her. During the initial consultation, Ms. Campbell was very thorough and answered all of my concerns. She assured me that this was not an overnight fix, however, it took less than three (3) months to resolve. Ms. Campbell was available every step of the way. I rarely called or emailed her because she always kept me in the loop. Every case is different but I am glad mine was quick and painless. I would recommend LemonLaw123 to anyone without any reservations. I could not have asked for better representation. Thank you!!!!
