The 2022 CT5 is still relatively new, but early pattern failures on the 2.0T engine are causing catastrophic damage at surprisingly low miles, while the 3.0TT has proven far more reliable. Transmission and cooling issues are emerging as secondary concerns.
Symptoms: Sudden loss of power with metallic knocking/rattling from engine bay, Check engine light with multiple misfire codes, Oil consumption between changes (1+ quart per 1,000 mi), Metal shavings visible in oil during changes
Fix: Complete engine rebuild or short-block replacement required. GM has extended warranty coverage on some VINs but not all. Typical repair involves 18-24 hours labor for short block R&R plus machining if salvaging heads. Root cause appears to be piston ring land failure leading to oil starvation and bearing damage.
Estimated cost: $8,500-14,000
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Transmission fluid puddles under vehicle (bright red fluid), Harsh or delayed shifting when transmission runs hot, Transmission temperature warning on dash, Fluid level drops requiring frequent top-offs
Fix: External cooler lines crack at crimp connections or corrode through at brackets. Replacement involves 2-3 hours labor for line set plus system flush and refill with Dexron ULV fluid. Inspect all hard lines and rubber sections — often multiple leak points develop simultaneously.
Estimated cost: $600-1,200
Transmission Mount Failure (10-Speed)
Occasional · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive vibration at idle in gear, Visible transmission sag on driver side when inspected on lift, Harsh engagement during aggressive acceleration
Fix: The driver-side transmission mount tears at the rubber isolator, allowing excessive movement. Requires subframe support and 3-4 hours labor to replace. Use OEM mount only — aftermarket versions fail faster. Check engine mounts at same time as they often follow.
Estimated cost: $500-800
Fuel Filter Clogging (Premature)
Occasional · medium severity
Typical onset: 25,000-50,000 mi
Symptoms: Intermittent loss of power under load, especially uphill, Extended cranking before engine starts, Rough idle or hesitation during acceleration, Check engine light with fuel pressure codes (P0087)
Fix: In-tank fuel filter clogs prematurely, likely due to contamination from ethanol-blend fuels degrading tank liner material. Requires tank drop and sender unit replacement (filter non-serviceable separately). 4-5 hours labor. Recommend fuel system cleaner treatment at every oil change as preventive.
Estimated cost: $800-1,400
Curtain Airbag Deployment Fault (Recall-Related)
Rare · high severity
Symptoms: Airbag warning light illuminated on dash, Side curtain airbags may not deploy in side-impact crash, No physical symptoms visible to driver
Fix: NHTSA recall for side curtain airbag inflator mounting bracket defect. Dealer-only repair involving bracket replacement and system reset. 2-3 hours labor, covered under recall at no cost. Check VIN against open recalls before purchase.
Estimated cost: $0 (recall repair)
Lighting Control Module Software Glitch
Occasional · low severity
Symptoms: Exterior lights (headlights, taillights) flash or flicker randomly, Auto high-beam function stops working, Daytime running lights fail to illuminate, Dashboard warning for exterior lighting malfunction
Fix: Software bug in lighting control module causes erratic operation. Covered under recall — requires dealer reflash, takes 1 hour. Some units need hardware replacement if reflash fails (module located behind glove box, 2 hours labor).
Estimated cost: $0-600
Owner tips
On 2.0T engines: religiously check oil level every 500 miles and use only Dexos1 Gen 3 oil — consumption above 1 qt per 3,000 mi is your early warning
Change transmission fluid at 50,000 mi even though GM says 'lifetime' — the 10-speed is sensitive to degraded fluid
Run Top Tier fuel exclusively and add fuel system cleaner every 5,000 miles to combat filter clogging
Verify all recalls completed before purchase — use NHTSA VIN lookup tool
Buy the 3.0TT V6 version without hesitation, avoid the 2.0T like the plague unless it has documented proof of short-block replacement under warranty.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence: DRLs that do not deactivate as intended may result in a glare, reducing visibility, and increasing the risk of a crash.
Remedy: The body control module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters were mailed January 23, 2023. Owners may contact GMC customer service at 1-888-988-7267, Chevrolet customer service at 1-800-222-1020, or Cadillac customer service at 1-800-458-8006. GM's number for this recall is N222386380.
