Top 2 Causes Why A Hybrid Vehicle Won’t Start
The most common problems that cause your Hybrid Mercedes-Benz not to start. This guide discusses the top 2 causes why a hybrid vehicle won’t start.
Why does my vehicle not start?
One reason why your vehicle is not starting is because the hybrid system is malfunctioning. Many units on the Mercedes-Benz Hybrid are connected to the high voltage or hybrid system, so if one unit in the high voltage (HV) system is not working, the whole HV network will fail, and the engine won’t start.
For example, if you have a bad AC compressor connected to the hybrid system, the vehicle will not start because the system is not working correctly.
Parking your vehicle for a long time can wear out the battery, preventing the car from starting. In this case, the hybrid battery will show a 15% charge or below and will need to be recharged or replaced.

The two most common problems with Hybrid Systems
- Power Electronic Module Failure
- High Voltage Hybrid Battery Failure
Almost all hybrid vehicles that refuse to start are diagnosed with a faulty power electronic module, which is not a cheap or easy fix. Hybrid Battery replacements can cost around $15,000, and Power Electronic Module replacements can cost between $10,000 and $12,000.
Diagnose and Repair Hybrid Vehicle
- Diagnose the vehicle using an advanced scanner – Scanning the vehicle will tell you why the vehicle is not starting, which will help you ease the work.
- Find a reliable shop – Before you take your vehicle in for repairs, contact the shop because many mechanics do not know how to repair a Hybrid or High-Voltage vehicle.
- Hybrid Vehicles are high-voltage— For complicated and dangerous repairs, it is better to let someone who knows how to work with high-voltage vehicles do the work rather than do it yourself because the high voltage is dangerous and deadly.
Hybrid Vehicles are great cars, but not all mechanics know how to work on these cars properly when it comes to complicated repairs. We have tutorials on our website that walk you through how to replace some parts, but be careful! You are working around high voltage. Always wear the proper protective gear, and you must know that when working with high voltage.
For all repairs and errors, we recommend investing in the YOUCANIC Full System Scanner, which can read and clear fault codes through every car’s control module, including hybrid vehicles.
High voltage can cause injuries or death, and that is one of the reasons why many mechanics and repair shops will turn you down and tell you that they don’t want to work on hybrid systems. If you decide to work on hybrid vehicles, you must get training first on handling high-voltage electric vehicles.
