2018 BMW X1 Engine Problems

“On May 20, 2026 We were in Mt Dora, FL We were approaching a red light. Cars were stopped in front of us and cars were beside me and behind me. As I slowed down the car just stalled out. It completely turned off while I was in drive. I immediately tried to start it. Then I put my foot on the brake and put it in park and turned on my hazard lights. I waited about 3 minutes and started it up. It was so scary because we could have been hit from behind.”

“The contact owns a 2018 BMW X1. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. Additionally, the vehicle shuddered significantly upon depressing the brake pedal. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the evaporative emission control circuit had failed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 63,000.”

“Car does not idle when first starts. Shifting into reverse causes car to nearly stall. To avoid this, I have to touch the accelerator with extra pressure which causes the car to jerk uncontrollably backwards. This is a known fault on X1 BMW’s. BMW requires $300-500 to complete a software update with no guarantee this will correct the problem. The software update was completed once before in 2019 and the problem persists. They are asking for another payment for another update with no guarantee.”

“Car began to make a loud humming noise from the engine compartment and the car went stiff. The check engine light came on and when taken to have the light looked at, it showed a faulty thermostat.”

“There is an issue with the X1 series of BMWs where the system shuts down after a cold start. This car displays alerts on the dashboard, and BMW service has confirmed that there are two firmware updates available to fix the issues. However, instead of providing the updates at no charge, they are asking for almost $1,000 for the firmware update. Forum discussions indicate that this issue causes the engine to stop after a cold start, which is extremely challenging, especially when leaving a garage into oncoming traffic, as the car just shuts off. …”
