I parked the vehicle in a parking lot. I walked away and it immediately started smoking. Shortly after that, flames appeared coming from the hood. Shortly after that, the entire vehicle was engulfed in flames.

I brought my car in for routine service and was told I needed a rear main seal. I had the car inspected when I purchased it appx 13k miles ago because I saw online there was a lot of people having this issue with their vehicles. It’s a known manufacturer defect. At that time there was no issue. Now at 40k miles it began to leak. This is round about the mileage most people have experienced this issue. A car with 40k miles shouldn’t have a defect like this that could cause the vehicles oil to leak out the seal and destroy the motor. I believe MBUSA should be replacing all of these seals on all of the affected vehicles. A consumer shouldnt be charged $6500 at 40k miles to repair a seal that is failing on so many vehicles.

I was driving about 30 mph and getting on to the highway. Once I got on a beep came on from the car and every single warning light came on the car. Check engine all warnings including emergency brake collision warning the list goes on and on. I immediately got off the highway and once I got to a complete stop the car was barely accelerating. I wasn’t able to shift gears from drive I was stuck in drive. Couldn’t park the car reverse or anything. I had to turn the car off. The car didn’t turn on and then after 5 minutes it turned back on. This is 1 week after me receiving the car back for the same issue. This was the 2nd occurrence of this and when I dropped it off at the dealer they had it for 2 weeks and they “fixed” the issue. There is obviously something wrong with the car and has several problems.

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 2019 Mercedes-benz E-class Wagon verdict →
