McLaren GTS Common Problems & Reliability
The newest grand tourer in McLaren's range. As a very recent model, public discussion is limited so far, but the reports that do exist point to wastegate/TCU-related faults and long dealer turnaround times.
Frequently asked questions
What's the wastegate/TCU issue reported on some new GTS cars?
At least one detailed owner account describes a nearly new GTS spending months in an official service centre for a wastegate/turbo control unit (TCU) related fault, compounded by parts delays and communication problems. As a very new model, it's too early to know how widespread this is, but it underlines the value of having an independent second opinion available if dealer turnaround stalls.
What should a new GTS owner do if service turnaround is slow?
For complex faults like wastegate/TCU issues, getting an independent diagnostic opinion in parallel with a dealer claim can help confirm the fault and, in some cases, speed up resolution — particularly for owners in Europe who don't want to be solely dependent on one service centre's queue.
Need a proper diagnosis, not a guess?
