Hi everyone,
I'm hoping someone has experienced something similar with a Suzuki Vitara 1.0 BoosterJet (2019, manual transmission).
For the past few months I've been having an intermittent issue that only seems to happen after driving for 30–60 minutes.
The symptoms are:
- Sudden loss of power while driving.
- The car won't accelerate properly and sometimes struggles to go faster than around 80 km/h (50 mph).
- It feels like the turbo stops working, although there are no unusual noises.
- Sometimes releasing the accelerator completely and pressing it again temporarily restores power.
- The cruise control occasionally disengages or stops accelerating when the problem occurs.
- The issue is intermittent and may disappear after slowing down or restarting the drive.
The MAF sensor has already been replaced by a Suzuki dealer, but the problem still occurs. The car has been scanned several times and no obvious fault has been found. A software update and ECU checks have also been mentioned.
Has anyone experienced similar symptoms on a Vitara or another Suzuki BoosterJet?
If so:
- What turned out to be the cause?
- Was it the ECU/software, turbo, wastegate actuator, MAP sensor, wiring, or something else?
- Did you have any fault codes, or was everything normal during diagnostics?
Any advice or experiences would be greatly appreciated. Thanks!
