A cheap, spacious crossover with a genuinely alarming brake-booster problem — buy it for the price, not the peace of mind.

Every documented failure, earliest first

Ordered by the mileage the problem typically appears. VERY HIGH confidence means it's tied to a documented NHTSA recall, and 2 of these are rated Critical.

20k–60k mi● Critical$400–$900VERY HIGH
Brake vacuum/booster pump failure causing hard, unassisted brake pedal — subject of NHTSA complaints and a related recall campaign
How to catch it: Confirm the electric brake booster pump recall/campaign was performed at a dealer before buying; if the pedal ever feels hard, pull over immediately and get it towed, don't drive it home.
Source: documented (NHTSA recall)
30k–80k mi● Plan$300–$1,800HIGH
1.5T engine oil consumption, PCV valve failure, and turbo coking on early build engines
How to catch it: Check oil level religiously every fill-up and keep every oil change receipt — GM has quietly extended warranty coverage on documented oil-consumption cases.
Source: owner-reported (24 NHTSA complaints)
40k–90k mi● Critical$0–$2,500VERY HIGH
9-speed automatic hard shifts, hesitation, and TCM (transmission control module) failures tied to a software/hardware recall
How to catch it: Verify the TCM recall/reflash was completed on the VIN via the NHTSA recall lookup before purchase — this is a known catastrophic-feeling failure mode.
Source: documented (NHTSA recall)
50k–100k mi● Watch$0–$1,000VERY HIGH
Right front intermediate driveshaft failure (AWD models) per recall — can cause sudden loss of drive or noise
How to catch it: AWD buyers must confirm the driveshaft recall was completed; listen for clunking on acceleration during test drive.
Source: documented (NHTSA recall)
60k–120k mi● Plan$1,000–$2,200MODERATE
Timing chain stretch/tensioner noise on 1.5T engines from cold-start oil starvation history
How to catch it: Listen for a rattle on cold startup lasting more than 1-2 seconds — that's your warning to inspect the tensioner before it lets go.
Source: multi-source pattern (AI synthesis)
80k–130k mi● WatchvariesVERY HIGH
Front door window glass improperly tempered per recall — can shatter unexpectedly
How to catch it: Confirm recall completion — this is a free fix, no reason it should still be outstanding on a used unit.
Source: documented (NHTSA recall)
