FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The active brake assist front radar sensor is defective. Mercedes Benz USA has failed to provide the part for repair even through the vehicle is only a few years old. They claim the parts on back order until April 2024, which is totally unacceptable. Several Mercedes Benz dealerships in the United States do have the part but refuse to release it to other dealerships.

VISIBILITY/WIPER, STRUCTURE:BODY
2015 AMG GLA-45. Sunroof violently broke, opening from front (normal is back) and sticking up 3-4 inches. Luckily this happened in our garage not moving, while simply pushing Close Sunroof button. If this had happened on the highway, it could have ripped off and killed somebody. Dealer says common problem, as soon as I brought the car in they said “sunroof warranty job” but the car is actually out of warranty. MB Natick Mass dealer is charging $3000 to replace motor, track, hinges, wind deflector. Can’t be closed manually even by dealer so car useless for two weeks while waiting for MB Corporate to review case for recall or complimentary repair due to liability. Today they refused to cover the repair cost or add car to recall list. NHTSA should know this car has ~26,000 miles on it and we’ve only opened/closed the sunroof perhaps ten times since buying it new. The sunroof assembly is obviously defective from the factory and was a “timebomb.” If it broke on the highway, lifting up from the front, it could have flown off and caused an accident and/or killed somebody behind us. Scary.

TIRES:TREAD/BELT, TIRES, TIRES:SIDEWALL
I have a zero point dmv clean record!! Tires are dysfunctional poorly made235/55 R18 The front tires are ready to blow out and look /feel very unsafe to drive no blow out yet - however last 6 months many people have noticed POOR TRACTION & asked if the car tires need air. No air WAS NEEDED!! Continental offered 40% off for replacement tires. This is unacceptable ! These are not industry safe and continental stated there’s no mileage warranty! Who gets all new tires at 26,500 miles. I’m a mom going to the grocery store and the mall! My brand new 2021 leased Car now has approx. 26,500 miles . Bought October 2020! Front tires are near bald. Back tires are nearly worn as well. Car was in & serviced at Mercedes’ where point inspections prove NO ALIGNMENT ISSUES 04/2022 and prior service dates tires were rotated 4 times and all service schedules were completed! Assumptions were made that I didn’t rotate tires as exscuse for POORLY MADE an outlet for UNSAFE TIRES. I live in a mild climate, Nor Cal and went to the snow one time. No car accidents, no beach salt climate. Also the Car is parked IN A covered garage area no excessive temps ON THE tires. No off roading. I have never seen a car tire wear like this. Colors been brown murky also continues alwaysneeds polish !!It’s not the Industry standard. It drives choppy also and reflects no air needed! For a Run flat expensive tire there’s no reason why it’s such a piece of junk. I’m middle aged and not a teenage driver this should of lasted ! Bought my car brand new nearly 50 grand Mercedes 2021! This is my 6th Mercedes’ and second leased Mercedes’ I’ve owned Escalade, 2 bmws, fiat, sabb, ml500 Mercedes’ , cla250 lease before this one that 2018 I got 40,000 miles only changed 2 tires due too moderate driving.

AIR BAGS
On December 4th 2021, while driving my airbags deployed without warning or notice. On a normal day at this time I would be traveling on the highway. The impact of the airport was so intense it stunned me and I thought another vehicle made impact. The chemicals of the airbag got al over my clothes, skin, and the interior. The steering column was sent to Germany for review and it was determined it was a technical issue that was not my fault However, in a different circumstance this could have caused a severe problem fatal collision woth another vehicle or object if I was traveling at a greater rate of speed. At the time of deployment I was traveling under 20mph. I did notice a warning lamp just a couple of hours prior to its deployment and called Mercedes to schedule a service to look into it. Approx 3 hours later the airbag deployed. The components in the steering wheel flew out causing damage to the interior of the vehicle and if it made contact with me could have cut me as well. I had discomfort from the chemical as a result of it getting all over my clothes, hair and skin. I was bruised and mentally impacted. I drive with the fear an airbag can deploy at any time in any vehicle I'm traveling in and cause me or my daughter bodily harm, damage or death

POWER TRAIN
I was parked in a lot and turned the ignition on and selected "DRIVE" but when I started to pull away the vehicle went backwards instead of forwards (as though "REVERSE" had been selected). I switched back to PARK, then selected DRIVE again and the vehicle once again went backwards. I then turned the engine off altogether and restarted it and this seemed to clear up the problem as now the vehicle went forwards when in DRIVE. No damage, or injuries, but of course very concerning from a safety point of view which is why I am reporting this. Mercedes did check the vehicle out the next day and could not locate any problem.

UNKNOWN OR OTHER
Plastic shoes broke on moonroof causing moonroof to be inoperable. Shoes are very fragile and difficult to replace. Many users have this problem. Broken shoes do not allow car to be driven with moonroof open as roof may fly upward and detach from vehicle. Moonroof lubrication is supposed to be part of maintenance schedule, which I have religiously adhered to, but dealership either ignored this maintenance step, or shoes broke anyway. Very expensive repair requires dropping of headliner. Please issue a safety recall.

Sunroof shoes have deteriorated and panoramic roof has become loose off the rails. This is a highly disturbing erosion putting drivers and other vehicles on the road in danger. I have found hundreds of reported cases of the same issue with no recall in place.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
I was driving the car at about 70 mph on an interstate highway during "rush hour" traffic when the Electronic Stabilization icon flashed on the dashboard screen and the car began to decelerate. I pressed on the accelerator pedal but the car continued to coast. A second or two later the dashboard screen flashed a warning stating something like "Brake assist activated" and the vehicle began to aggressively brake. I was in the middle lane of the interstate with vehicles around me travelling at 65 to 75 miles per hour and I could see a car rapidly approaching me from behind. It was apparent to me that my vehicle was going to come to a rapid stop in the middle of a busy interstate highway and that I was going to be struck from behind by one or more cars travelling at a high rate of speed. I did not think that I would survive such an impact and checked the right hand lane and noted no vehicles. Since all I could do with the car at that point was steer, I pulled my car into the right hand lane, attempting to avoid an inevitable high speed rear end collision. Unfortunately by that time my vehicle was still braking and travelling at a relatively low speed and was struck in the right rear area by another vehicle that was travelling at a much higher speed. Fortunately no one was injured in this crash, but there was extensive damage to both vehicles. I had not previously experienced this type of malfunction of the emergency collision avoidance system but on reviewing Mercedes Benz owners' blogs it is clear that this is not an isolated occurrence. I note that the owners of other car manufacturers have also experienced issues similar to mine, although most of them occurred in less dangerous situations and did not result in a crash. I believe that this "safety" system is flawed and placed my life, and the lives of others, in grave danger, much like the Boeing 737 Max issue, and that a recall and investigation is needed to prevent fatalities resulting from their malfunction.

Faulty Panoramic Sunroof. I took the car to the dealer service to have the sunroof checked since it won't close all the way that the guide rails jammed and faulty. It is too expensive to get it fixed after taking to Mercedes. I haven't owned the vehicle very long and only used the sunroof maybe once or twice and it stopped working. This should be a recall and I shouldn't have to pay to fix it. I am worried that it might come off while driving, for now it is sealed with wrap.
