2019 Alfa Romeo Giulia

For 2019 the 2.2 diesel gained AdBlue and Euro 6d compliance with 160PS and 190PS outputs, and an 8.8-inch screen with Apple CarPlay and Android Auto became standard. These updates make the diesel Giulia a cleaner ULEZ proposition.

  • •2.2 JTDM-2 diesels updated to Euro 6d with AdBlue and 160PS/190PS outputs
  • •8.8-inch infotainment with Apple CarPlay and Android Auto fitted as standard
  • •Quadrifoglio gained port injection as part of its engine update
  • •All UK cars kept the ZF eight-speed automatic; no manual was offered

All Known Issues

Relay Failure & Random Limp Mode

SeriousElectrics & Electronics

A bank of six micro-relays located behind the front-right (passenger side) wheel well liner is a major failure point. Sticking relays for the starter or auxiliary water pump can cause "no-crank" scenarios, parasitic battery drain, or random "limp mode" where the car loses power.

Est. Repair Cost: £50–£150 (Proactive replacement)
Warning Signs:

Random limp mode, No-start/No-crank, High-pitched whine after shutdown, Sluggish acceleration in Dynamic mode

What to Inspect:
  • Check if the relays (Mopar 6106093AA or updated 68530205AA) have been replaced
  • Listen for noises from the passenger wheel well area after the car is off

Parasitic Battery Drain & AGM Upgrade

ModerateElectrics & Electronics

The Giulia is extremely sensitive to voltage. Factory EFB batteries often struggle, leading to "ghost" faults. Many owners upgrade to a larger H8 (LN5) AGM battery (95Ah) to solve these issues. Parasitic drain can also be caused by the USB hub or BCM staying awake.

Est. Repair Cost: £250–£600
Warning Signs:

"Start-Stop Unavailable" message, Random EML/Airbag warnings at start-up, Keyless entry failure, Dead battery after 3-4 days of no use

What to Inspect:
  • Age/type of battery (Upgrade to AGM is recommended)
  • Check if USB ports stay lit after car is locked
  • BCM software update status

Suspension Bushing & Alignment Issues

ModerateSuspension & Chassis

Front lower control arm bushings wear prematurely, and the aggressive factory "Ackermann" steering geometry causes significant tyre scrubbing on full lock. This is often misinterpreted as a mechanical fault but leads to rapid inner tyre wear.

Est. Repair Cost: £350–£800
Warning Signs:

Tyre "skipping" on full lock, Heavy inner tyre wear, Squeaking/creaking over speed bumps

What to Inspect:
  • Inner edges of front tyres
  • Listen for suspension knocks on test drive
  • Service history for specialized 4-wheel alignment

Buying Tips for 2019 Alfa Romeo Giulia

  • Scan for emissions codes and check the AdBlue range reading
  • Ask for evidence of the 2019 software update and any Quadrifoglio injector work
  • Check the tyre brands; mismatched budget rubber hides alignment neglect
