In July 2022 I was a few miles from my home when the cluster starting showing warning lights. It started scrolling inoperative power brakes, inoperative steering and inoperative parking. Also the cluster was completely lit up. I turned the car around and put it in my garage. This is where the issues really started. The car would not go into park or turn off. I sat with my foot on the brake for 30 minutes trying to continue turning the car off or put in park. I finally had my wife take the key and walk 1/8 mile away before the care would turn off. I had the car flat bedded to Mercedes of Cherry Hill. They had the car for several days. They called me and asked if the car was flooded or hit. I told them no to either. I explained how the car is garage kept. I was talking to my mechanic who services the car and started telling him the story. Before I could say anything he asked me if they asked me if the car was flooded? I said how did you know that? He told me that he has several customers with similar issues with the wiring harness in the front bumper. He told me that it's a bad design where water gets in and burns the harness out. The scary issue is the car not turning off or going into park. If my wife who drives the car was by her self had this issue what would she do?

A driver in my household was driving at normal speeds and smelled smoke in the cabin. She pulled over immediately to the nearest gas station. In that short time, there were FLAMES coming from the center console area. She ran inside to get employees with fire extinguisher. The fire was put out and police/fire department were called. The car was un-drivable, and my insurance declared it as a total loss (it would cost more to repair than the current blue book value). I had a similar problem previously with a Mercedes 2014 CLA250. That was a smaller fire, but melted the console area. I will be submitting a report for that one as well, even though it happened several years ago. After that incident we went back and forth with MB corporate and ultimately took it to dealer and ended up trading in for this one. Both fires were electrical fires from wires underneath the center console.

STRUCTURE:BODY, VISIBILITY:SUN/MOON ROOF ASSEMBLY
Panoramic sunroof slider shoes failing, being cracked and stuck in the railing, causing a sunroof malfunction. The main concern of danger is that during closing the sunroof, with a lack of support glass bangs down coming in contact with some metal parts, risk of being shattered and cause injury to passengers. In my specific car, somehow all 4 shoe sliders failed on a car with less than 50,000 miles. While researching, the issue is raised by many other owners and appears to be a wide spread systemic flaw. https://www.glaowners.com/threads/shoe-on-rail-of-panoramic-sunroof-broke.26716/page-5

ELECTRICAL SYSTEM
My backup camera doesn’t work at least half the time. The screen is completely black when I start the car, and the radio doesn’t even come on until I’ve been driving for about 15 minutes. The car does not charge either of my phones even with the cord provided by Mercedes that links to the screen. I depend on that for navigation, and the screen remains black. Since the phone won’t charge either, it runs out of charge quickly when trying to use it by itself for navigation.

Transmission problem. On several occasions while driving, the car has lurched to a stop because gear changed suddenly from Drive to Park. At other times, the engine revvs and slows when it suddenly switches from Drive to "M1." After stopping, it goes back to "D" on its own. Serious safety issue, as I can get rear ended in traffic, or cause an accident for stopping without notice. I have one photo of the sudden transmission switch to M1 (today). Car has been towed to Mercedes service department; no other inspection yet. No warning lamps. Only that it is happening more frequently.

STRUCTURE:BODY
While driving the vehicle on the highway the front panel immediately in front of the panoramic roof was ripped off. The glue holding the panel in place was defective and is a known issue that currently has a recall out issued by Mercedes Benz. However the vin of our vehicle does not fall under the recall per my conversation with a MB rep. Mercedes Benz knows that this is a problem and will not add this vehicle to the recall. The glue holding the panel down is known to become weakened due to sun exposure. No lights on the dash are associated with this issue. The panel could have ripped off and hit a vehicle traveling behind us and caused an accident.

On a few occasions, the car shifted into neutral on its own after being in the drive gear. This is quite dangerous and unsafe. There are no warning lights or indications. I noticed this problem a few months ago and it has happened a handful of times. I have don’t extensive research on similar problems and have only found forums with other gla drivers experiencing the same problems. There is no recall that I can find regarding this issue. The dealer is also unaware of this issue.

I consider this issue a SERIOUS SAFETY ISSUE that could be LIFE-THREATENING and all Mercedes-Benz service departments should be alerted to the problem. Mercedes-Benz should issue a revised, more user-friendly label so independent tire shops will not misread the label and over-inflate customers' tires. The tire inflation specifications provided for this vehicle, located both on the B-pillar and gas filler flap, are configured poorly and lead techs, both at Mercedes service departments and independent tire shops, to grossly over-inflate the tires. Please see the attached photo of the gas filler flap sticker on our AMG GLA 45. Our car has 20" tires and the techs incorrectly read the tire inflation pressures as 42 psi front / 46 psi rear. These are the correct pressures for a fully loaded vehicle, a situation that we seldom see. This represents over-inflation of 8 psi (22%) front and 13 psi (39%) rear, creating the potential for blowouts, compromised handling, and loss of control. Technicians read the label as 19" tires receiving the day-to-day tire pressures and 20" tires receiving fully loaded pressures creating a life-threatening safety issue. I have tried to address this problem with W.I. Simonson in Santa Monica, trying to contact our service rep, their tire "guru", and the GM. I've left two voicemails for each of them and have received no response whatsoever. I tried to alert Mercedes-Benz North America (800/367-6372) with the following results: 1) Called 15 August 2022, explained the problem and receiving case #2-31456230028, was told that a rep would contact me within 48 hours. 2) Called 23 August 2022, was told that a rep had tried my wife's number once. She has no record of a call. 3) Called 11 September 2022, provided the case number and after 40 minutes the call was dropped. 4) Called back immediately on 11 September 2022, provided the case number and after 27 minutes the call was dropped. I am available anytime if you have questions.

POWER TRAIN, VEHICLE SPEED CONTROL
Upon start, got a "reverse not possible" warning. Tried to drive home, but shifting was very erratic and car slowed dramatically between shifts. On several occasions, cars behind me had to swerve to avoid me. And, if I would have had to reverse out of danger, I would have been in serious trouble. After too many close calls, I stopped to arrange a tow. When I returned to the car to move it, the problem went away. I am afraid to put my family in this car.

P052E-71 The valve for crankcase ventilation has a malfunction. The actuator is blocked. Was initially intermittent but seems to be getting worse. Dealer quoted ~2k to repair, which seems astronomical for a PCV valve. Common problem with these engines.

POWER TRAIN
Summary: Transmission automatically shifts out of drive into neutral. Loss of ability to accelerate when transmission shifts to neutral. No preemptive warnings from the vehicle prior to incident. After transmission shifts to neutral, warning displaying, "Do not shift, bring vehicle for service" appears on multifunction display. Same safety issue as described in NHTSA recall #: 21V-033. Sequence of events: When driving on the highway, transmission automatically shifted from drive to neutral, resulting in a loss of power. Was able to coast to side of highway safely, but could have resulted in an accident with multiple vehicles on busy highway. The vehicle was towed to a Mercedes Benz dealership where the dealership inspected the vehicle and diagnosed the problem as low main battery voltage preventing proper communication among the powertrain control modules. Battery was replaced by dealership as recommended but problem still persists. The issue is reproducible and occurs every time after about 20-30 minutes of normal driving. Additional Details: - Transmission/transmission control module failure while vehicle was in motion. Vehicle is available for inspection upon request. Problem is reproducible and occurs after approximately 20-30 minutes of normal driving. - Sudden and unexpected loss of ability to accelerate significantly increases the risk of a crash. - The vehicle was inspected and diagnosed by Mercedes Benz of Owings Mills in Owing Mills, MD. However, the problem was misdiagnosed by the dealership. - No warnings or messages displayed in the vehicle prior to each occurrence. However, vehicle displays warning message after each occurrence. - Have been in contact with Mercedes Benz USA in regards to this issue, but they have declined to assist with recalling the vehicle.

STRUCTURE:BODY, STEERING, SUSPENSION
I was involved in an auto accident on 3/1/22 I no longer have confidence or feel safe driving the 2019 Mercedes GLA250 after having a minor" accident and repairs totaling $15,008.53. The steering wheel locked and the left tire was knocked out of place. According to Mercedes, repairs were required to the suspension system, new struts, new knuckles, steering gear. I am terrified to continue driving the GLA250 model and am anxious and fearful off having another accident which could very well result in a fatality. The first estimate for repairs totaled $5,385, followed by a second estimate of $13,776 and then a third estimate of $15,008.53.

UNKNOWN OR OTHER, LANE DEPARTURE: WARNING
I bought this car at end of June, dealership never disclosed information that car had an active recall… I looked it up on NHTSA and sure enough I need a SIM card for emergency service, the site says it will be done over the air wave , I brought it to the Delray Beach Fla dealership who told me they couldn’t update it and had no idea when and how this recall will be handled. I have called the Nhtsa # every day for 2 weeks, no one ever answers the phone, I have left numerous messages, but no call backs, please advise me when and how this recall will be done ? I have the Nhtsa app and there is no information from anyone anywhere , very inconvenient for me to leave car at dealership for 5 hours and have them tell me not only that they can’t fix the recall but they have no idea when or how it will be done.. The website states that if it cannot be done via airwave that the dealership will update but no one seems to have an answer??? So I just spent 35,000 on a car that I can’t use for the purpose I purchased it for and no answer, please advise when and how this recall will be handled.
