Recall 17V114 affects 307,629 2015-2017 Mercedes-Benz vehicles across multiple models for an overheating starter current limiter. Repair is free at any franchised Mercedes-Benz dealer.
Mercedes-Benz is recalling 307,629 2015-2017 C300, CLA250, and GLC300 vehicles because repeated starting attempts can overheat the starting current limiter when the engine or transmission will not turn over. If the limiter overheats, nearby components can melt and raise the risk of a fire; the Mercedes-Benz dealer repair will be free once available.

What's wrong?
The starting current limiter in affected 2015-2017 Mercedes-Benz vehicles is part of the starter electrical circuit. Its job is to manage the heavy electrical draw used when the starter motor turns the engine during a normal start. When the engine and transmission can turn freely, the limiter works within its intended current range.
The problem starts when engine or transmission damage prevents the starter from turning the engine over. If the driver keeps trying to start the vehicle, the starter motor keeps asking for high electrical current while it is blocked. That overloads the starting current limiter, and the limiter can overheat because it was not designed for that extreme condition.
There is no warning sign before failure. The vehicle fails to start, but that no-start condition does not give a separate warning that the starting current limiter is overheating.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
An overheated starting current limiter can melt nearby components and increase the risk of a fire. There is no listed warning sign before overheating, so confirm whether your VIN is included and arrange service before routine driving. Repair will be free at any franchised Mercedes-Benz dealer once available.
What should I do?
- Check your VIN to confirm your 2015-2017 Mercedes-Benz C450, C300, CLA250, AMG CLA45, GLC300, E300, E400, AMG E43, Gla 250, or C350E is included in this recall.
- Use the Mercedes-Benz owner letter if you have it; the notice was mailed after August 31, 2017.
- Contact Mercedes-Benz customer service at 1-800-367-6372 with questions and reference recall number 17V114 when you call.
- Ask a franchised Mercedes-Benz dealer about the free starter electrical-line fuse repair that prevents the starting current limiter from overheating.
- Avoid repeated start attempts if the engine or transmission will not turn over, since repeated starter use is tied to the overheating risk.
What happens at the repair
Mercedes-Benz lists the dealer fix as installing an additional fuse in the electrical line to the starter. Once the repair is available for your VIN, a Mercedes-Benz technician adds that fuse to help protect the starter circuit from overheating after repeated start attempts, and parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the New Vehicle Limited Warranty, not through a separate reimbursement program, because the involved vehicles remain under that warranty. Ask the service desk how warranty coverage applies if you have related repair paperwork.

Frequently asked questions
What is recall 17V114?
Recall 17V114 covers 307,629 2015-2017 Mercedes-Benz vehicles with a starting current limiter that can overheat after repeated starter attempts when the engine or transmission does not turn over. Mercedes-Benz dealers install an additional fuse in the starter electrical line for free.
What should I do if my 2015-2017 Mercedes-Benz C450, C300, CLA250, AMG CLA45, GLC300, E300, E400, AMG E43, Gla 250, or C350E is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 17V114. If it is, contact a franchised Mercedes-Benz dealer and reference recall number 17V114 or Mercedes-Benz recall number 2017080002. The dealer remedy is an added fuse in the starter electrical line.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Mercedes-Benz says dealers will install the additional starter-line fuse free of charge. The free repair applies at franchised Mercedes-Benz dealers.
Is it safe to drive my Mercedes-Benz before this repair?
The stated risk is fire if the starting current limiter overheats and nearby components melt. If the engine or transmission does not turn over, avoid repeated starter attempts and call a Mercedes-Benz dealer for guidance before moving the vehicle.
What if I bought my Mercedes-Benz used?
The free recall repair still applies. Recalls follow the VIN, not the first owner, so a used vehicle is still eligible when its VIN is included. Check your VIN, then contact a franchised Mercedes-Benz dealer with recall number 17V114.
